-## [3.0.3] - 2026-06-12
+## [3.9.0] - 2026-07-14
+
+### Added
+- **Era Parsing Engine**: Upgraded the `ParseModule` and Lexer to natively support parsing historical and future era dates with explicit markers (e.g. `200 BC`, `BC 200`, `2026 CE`). Supports both leading and trailing formats and flawlessly converts to the astronomical ISO 8601 year.
+- **Era Formatting & Getters**: Added native support for the `{era}` and `{eraYear}` formatting tokens. Introduced `.era` and `.eraYear` getters on the core `Tempo` class for zero-cost access to historical date components.
+- **Auto-Meridiem Spacing**: Implemented the `:space` modifier for the `{h12}` formatting token (e.g., `{h12:space:dots}`). This enables typographically correct spacing before automatically injected meridiems (e.g., `"10:30 a.m."`).
+
+### Changed
+- **Documentation Alignment**: Cleaned up `tempo.config.md` to remove deprecated module references, perfectly aligning examples with the `tempo-workspace` ecosystem (`FinancePlugin` and `AstroTerm`).
+- **Getter Documentation**: Created `tempo.getters.md` as the definitive, educational conceptual guide for utilizing Tempo's zero-cost evaluation getters.
+
+### Fixed
+- **Core Typings**: Resolved `any` leakage in `Tempo` core methods by injecting strict overloads for `until()` and `since()` directly into `tempo.class.ts`, ensuring full IDE type-inference flows through to `.format()`.
+- **Documentation Badges**: Standardized the Shields.io badge layout across the monorepo to use `<p>` tags with `inline-block` styling, fixing horizontal alignment issues caused by VitePress CSS overrides and eliminating malformed HTML `<table>` hydration errors.
+
+## [3.8.0] - 2026-07-11
+
+### Fixed
+- **Plugin Argument Parsing**: Hardened `Tempo.extend` parsing logic to ensure single-argument discovery objects are not falsely popped as `options`.
+- **Registry Merge Contracts**: Corrected documentation in `tempo.registry.md` to accurately define `registryUpdate()` as additive-only, clarifying that `Tempo.extend()` only shadows explicitly wrapped proxy dictionaries (like `formats`).
+
+### Added
+- **Interval Primitive**: Introduced `Interval` as a core primitive in the `@magmacomputing/tempo` package, accessible statically via `Tempo.Interval` or as a decoupled named export. Provides robust `overlaps`, `abuts`, `contains`, `union`, and `intersection` capabilities for native Temporal and Tempo objects.
+- **Namespace Architecture (`defineNamespace`)**: Officially launched the new Namespace Plugin architecture. This provides a clean mechanism to attach grouped API surfaces (like `t.finance.*`) onto the core Tempo instance without polluting the global scope or the natural-language parsing engine.
+- **Strict Plugin Discrimination**: Core registration utilities (`definePlugin`, `defineTerm`, `defineModule`, `defineNamespace`) now strictly inject a discriminator `type` key (`'plugin' | 'term' | 'module' | 'namespace'`). This ensures internal registries and debugging tools can accurately categorize plugins without relying on loose structural sniffing.
+- **Finance Sandbox (`@magmacomputing/tempo-plugin-finance`)**: Introduced the community `finance` package as the official reference implementation for Namespace plugins, complete with best-practice dual-build (ESM/DTS) architectures using `tsup`.
+
+### Changed
+- **Build Pipeline Optimization**: Completely removed `esbuild` from the core transpilation pipeline in favor of a pure `tsc` + `Rollup` + `terser` architecture. This eliminates double-transpilation penalties, resulting in a cleaner, more efficient `dist/` build.
+- **ESBuild Decorator Mitigations**: Uncovered a significant bug in `esbuild`'s handling of TS 7.0's new, spec-compliant `__esDecorate` down-leveling where transpiled class expressions drop decorator replacements. Maintained the `Object.freeze` constructor workarounds across the ecosystem to ensure full immutability compliance while tracking upstream bundler patches.
+- **Documentation Architecture**: Completely overhauled the documentation repository to utilize a strictly-numbered directory structure (`1-getting-started`, `2-core-concepts`, etc.) that mirrors the VitePress UI 1:1, drastically reducing maintenance overhead and eliminating orphaned files.
+
+## [3.7.1] - 2026-07-08
 
 ### Fixed
-- **Sandbox License Inheritance**: Resolved an issue where `Tempo.create()` immediately severed the link to the global license state. Sandboxes now dynamically inherit the global environment's Premium license unless they are explicitly extended with their own dedicated license key via `Sandbox.extend({ license: '...' })`.
+- **License Admin Isolation**: Restructured the commercial licensing JWT payload to isolate administrative privileges (like `tempo-adm`) into a dedicated root-level `role` claim. This prevents internal admin flags from polluting the `scopes` dictionary and erroneously surfacing as "uninstalled premium plugins" in the `Tempo.terms` registry UI.
+
+## [3.7.0] - 2026-07-08
+
+### Added
+- **Runtime Versioning Registry**: Introduced a secure, static `Tempo.versions` registry. This provides zero-burden runtime observability of all loaded core modules and community plugins.
+- **Automated Plugin Versioning**: Community plugins now automatically inject their version via a custom ESBuild virtual module pipeline, eliminating the need for magic strings. Internal bundled terms (like `QuarterTerm`) seamlessly inherit the core `TEMPO_VERSION`.
+
+### Changed
+- **Internal Privacy Modernization**: Refactored internal runtime registries (including `_termMap` and other internal configuration variables) to utilize strict ECMAScript private fields (`#`), ensuring complete architectural security against prototype tampering.
+
+## [3.6.1] - 2026-07-06
+
+### Fixed
+- **Constructor Shorthand Resolution**: Fixed a critical `TypeError: invalid duration-like` regression introduced in 3.6.0. The `Tempo` constructor now correctly maps shorthand duration objects (e.g., `{ mi: 5 }`) to their fully-qualified `Temporal` plural equivalents (`{ minutes: 5 }`) before evaluating them against the underlying engine.
+
+## [3.6.0] - 2026-07-05
+
+### Added
+- **Shorthand Mutation Keys**: Added native support for Tempo's shorthand format tokens (e.g., `mi`, `ss`, `yy`, `ww`) across both `.add()` and `.set()` mutations, streamlining developer experience and aligning TypeScript definitions with the underlying runtime engine.
+- **Shorthand Duration Keys**: Expanded shorthand token support directly into the `DurationModule`. You can now seamlessly use shorthand keys for duration instantiation (`Tempo.duration({ mi: 5 })`), comparisons (`t.until(other, 'mi')`), and strict balancing (`t.until(other).balance({ largestUnit: 'mi' })`), bringing total API consistency across the core library.
+
+### Changed
+- **Enum Performance Optimization**: Upgraded internal dictionary traversals across the parsing engine to utilize native, memoized `.keys()` methods provided by the `enumify` registry, eliminating the overhead of standard `Object.keys()` iterations.
+
+### Fixed
+- **Prototype Bleed Vulnerability**: Replaced `in` operator checks with secure `.has()` methods across the core engine and duration parser, ensuring strict enum member validation and completely eliminating the risk of arbitrary property or method-based prototype leakage.
+
+## [3.5.3] - 2026-07-05
+
+### Added
+- **Flexible Epoch Getters**: Added a static `Tempo.epoch` getter that perfectly mirrors the instance `.epoch` property, enabling direct retrieval of current Unix timestamps (e.g. `Tempo.epoch.ss`).
+- **Static Now Modifiers**: Extended the static `Tempo.now(unit)` method to accept optional string units (`'ns'`, `'us'`, `'ms'`, `'ss'`), defaulting to nanosecond precision for strict backwards compatibility.
+
+### Changed
+- **DRY Refactoring**: Centralized instance and static `epoch` property calculations to a single internal static helper, ensuring absolute uniformity of mathematical transformations across the core library.
+
+## [3.5.2] - 2026-07-04
+
+### Added
+- **Minified Global Bundles**: The build pipeline now natively produces highly optimized, minified IIFE bundles (`*.min.js`) for both Tempo Core and all Community Plugins, significantly reducing payload size for developers using CDN `<script>` tags.
+- **Unified Global Namespace**: Re-architected the browser-global export strategy. Both the core library and all `<script>` tag plugins now elegantly attach to a single, collision-free `window.Magma` namespace (e.g., `window.Magma.Tempo` and `window.Magma.plugins.astro`), dramatically improving developer experience and eliminating global variable pollution.
+- **Timezone Formatting Modifiers**: The `{tz}` token now natively supports localized timezone name and offset formats via lowercase modifiers (e.g., `{tz:z}`, `{tz:zzzz}`). This allows developers to format timezones exactly as needed without relying on raw ID strings.
+
+### Fixed
+- **Module Augmentation Typings**: Hardened the "batteries-included" `tempo.index.ts` entry point by explicitly exporting core module types (e.g. `DurationModule`, `FormatModule`). This forces TypeScript to preserve their module augmentations in the compiled `.d.ts` bundle, guaranteeing that methods like `.until()` and `.since()` correctly appear in IDE autocomplete out-of-the-box.
+
+## [3.5.1] - 2026-06-28
+
+### Fixed
+- **Term Registration Resilience**: Hardened `Tempo.extend` with structural deduplication to safely ignore redundant registrations of identical core terms. This prevents edge-case term collisions (e.g., `qtr`) in mixed module-loader environments like Vitest where Node ESM and Vite may evaluate plugins multiple times.
+
+## [3.5.0] - 2026-06-28
+
+### Added
+- **Unified Plugin API Barrel**: Introduced `@magmacomputing/tempo/plugin-api` barrel export. This centralizes all plugin-authoring utilities (`defineModule`, `definePlugin`, `defineTerm`, etc.) and internal types into a single, highly discoverable endpoint. This architecture significantly cleans up application-level code and documentation by separating end-user imports from Plugin Developer imports.
+- **Strict Peer Dependency Validation**: Tempo Plugins now enforce strict `peerDependencies` on the new `plugin-api` barrel export, ensuring robust resolution for complex environments (like Smart CDNs or Vite) while preventing duplicate instances of internal utility functions.
+
+### Changed
+- **Documentation Overhaul**: Updated the installation documentation and template sandboxes (`index.sample.html`) to natively utilize the new `plugin-api` barrel. Refined CDN strategies into two clear paths: "Smart CDNs" (for rapid prototyping) and "Static CDNs" (for production builds using manual import maps).
+- **Temporal Native Support Roadmap**: Updated documentation to use evergreen wording for upcoming Node.js native unflagged `Temporal` support, removing explicit version claims (like Node.js 26) to future-proof the guides against shifting ECMAScript release timelines.
+
+## [3.4.0] - 2026-06-26
+
+### Added
+- **Dynamic Format Tokens**: You can now define custom format evaluators in the global registry via `registry.tokens`. Custom tokens receive the native `Temporal.ZonedDateTime` instance and a `context` payload containing configuration and chained modifiers, allowing for completely custom parsing or seamless `Intl` delegation.
+- **Compound Token Modifiers**: The compound date tokens (`{dmy}`, `{mdy}`, `{ymd}`) now support `:yy` modifiers (e.g., `{dmy:yy}`) to safely truncate their internal year components to 2 digits. 
+
+### Deprecated
+- **Legacy 6-Digit Tokens**: The `*6` compound date tokens (e.g. `{dmy6}`, `{mdy6}`) have been effectively superseded by the `:yy` modifier and removed from public documentation. They will remain in the engine indefinitely to guarantee strict backwards compatibility.
+
+## [3.3.2] - 2026-06-22
+
+### Fixed
+- **NPM Readme Metadata**: Fixed an issue where the `README.md` was missing from the `files` array in `package.json`, causing the `npmjs.com` registry page to show a blank README tab.
+
+## [3.3.1] - 2026-06-22
+
+### Added
+- **Slick Object Mutation API**: The `.set()` mutation engine now supports a "Slick-style" API for relative date/time navigation using object properties. You can now pass snippet-based keys with directional string payloads (e.g., `{ wkd: '>Fri' }` or `{ mm: '>-2' }`) directly to `Tempo.set()`.
+- **`ww` Token**: Added native `ww` (weeks) snippet token for relative week-based mutation math (e.g. `{ ww: '>1' }`).
+- **Extended Shorthand Modifiers**: Expanded the Slick Regex parser to natively support double-negation synonyms (`>-2` is correctly interpreted as backwards two steps), equality/anchor logic (`>=`, `<=`, `=`), and `+` and `-` as aliases for `>` and `<` within semantic loops (like `wkd`).
+
+### Changed
+- **Strict Key Validation**: Hardened the `conform()` layer to throw helpful console errors when users accidentally pass directional strings to standard keys (e.g. `t.set({ month: '>5' })`), politely redirecting them to the correct Slick property (`{ mm: '>5' }`).
+
+## [3.3.0] - 2026-06-21
+
+### Added
+- **Localization Modifier Registry**: Modifiers (e.g., "next", "last", "this") can now be localized via the `registry.modifiers` configuration. This allows defining custom words for temporal shifts (e.g., `'>': ['prochain']`) which seamlessly integrate with standard parsing and `#` shorthand syntaxes.
+
+### Changed
+- **Unified Registry Architecture**: Moved the top-level `modifiers` configuration key under the `registry` namespace (`registry: { modifiers }`) to maintain architectural consistency with formats and locales. Deep-merging ensures English default keywords remain active alongside custom localized additions.
+- **Lexer Token Cleanups**: Stripped hardcoded English keywords out of all internal Match regular expressions (`Match.modifier`, `Match.shorthand`, `Match.slick`), standardizing the engine on the symbolic modifiers (`>`, `<`, `=`, `+`, `-`).
+
+### Fixed
+- **Pre-filter Guard Numeric Safety**: Refined the guard-bypass logic to trigger *only* when the input string actually contains a registered modifier keyword, restoring proper strictness and fixing numeric-safety validation gaps for nanosecond epoch inputs.
+- **Lazy Evaluation Delegation**: Fixed a regression in format lazy-loading where built-in formats (like `{date}` or `{time}`) were temporarily eclipsed by empty registry instances.
+- **Trailing Affix Collisions**: Added explicit safety checks and warnings when a date unit is passed both a leading modifier and a trailing affix (e.g., "next May ago").
+
+## [3.2.3] - 2026-06-20
+- **Centralized Configuration**: Introduced `tempo.config.ts` and `tempo.config.js` discovery.
+- **Async Bootstrap**: Added `Tempo.bootstrap()` for safe, asynchronous ES Module configuration resolution without breaking the synchronous `Tempo.init()` API.
+- **CLI Scaffolding**: Added an `npx @magmacomputing/tempo scaffold:all` CLI tool to easily bootstrap `tempo.config.ts` and HTML sandboxes into projects.
+
+### Changed
+- **Zero-Dependency Resolution**: Implemented custom filesystem traversal to ensure robust config discovery without adding external dependencies (e.g., `cosmiconfig`).
+
+## [3.2.2] - 2026-06-18
+
+### Added
+- **New Format Tokens**: Added support for 6-digit compact date formatting tokens (`{dmy6}`, `{mdy6}`, `{ymd6}`) and short-year bounds (`{yywy}`, `{yyww}`).
+
+### Changed
+- **Intl Configuration**: Completely overhauled the `options.intl` resolution pipeline. Replaced brittle shallow-spread assignment with a robust, recursive `deepMerge` utility to prevent nested configuration clobbering (e.g. `dateTimeFormat` vs `relativeTimeFormat`).
+- **ISO Week Renaming**: Renamed the `{ww}` token to `{wy}` to provide better semantic alignment with week-of-year calculations and resolve ambiguity with structural tokens.
+
+### Fixed
+- **Configuration Security**: Hardened recursive object manipulation utilities (`deepMerge` and `deepFreeze`) against Prototype Mutation and Prototype Freezing Denial of Service (DoS) vulnerabilities by strictly guarding against `__proto__`, `constructor`, and `prototype` keys during object traversals.
+
+### Removed
+- **Redundant Format Tokens**: Removed uppercase format tokens (`{MER}`, `{HH}`, `{DAY}`, `{WW}`, `{MM}`) from the engine to strictly enforce the token modifier pattern (e.g., `{mer:upper}`, `{h24}`, `{dd:ord}`). This eliminates ambiguity and ensures all output routes securely through the `Intl` localization engine.
+
+## [3.2.1] - 2026-06-17
+
+### Added
+- **Ordinal Localization Fallback**: Implemented support for non-English `Intl.PluralRules` dictionaries. If an `ordinal` dictionary is provided in the global `locales` registry, Tempo natively evaluates the active plural category (e.g., `'one'`, `'other'`) and appends the correct localized suffix instead of defaulting to English.
+
+### Changed
+- **Documentation Restructuring**: Extensively reorganized the `tempo.cookbook.md` to group related functionality (e.g. merging `add()` math, grouping `.set()` boundaries, and isolating Timezones & Locales) for a more intuitive developer reading experience.
+- **Clarified Configuration Topology**: Updated `tempo.config.md` to remove outdated top-level keys (`ignore`, `terms`) from the Discovery Contract and explicitly document the availability of the `intl.durationFormat` option.
+
+### Fixed
+- **REPL Idempotency Warnings**: Added explicit warnings in the cookbook regarding `Tempo.init()`'s strict idempotency. `Tempo.init()` is designed to abort silently on subsequent calls to protect global state; `Tempo.extend()` must be used to hot-load configuration in continuous REPL environments.
+- **Sandbox Alias Collisions**: Hardened the `AliasEngine` collision detection to skip redundant alias registrations across the entire prototype chain, eliminating unnecessary console warnings during sandboxed `Tempo.init` invocations.
+
+## [3.2.0] - 2026-06-16
+
+### 🔒 Security & Licensing
+- **Domain-Locked Licensing**: Stabilized the premium plugin licensing engine with a robust domain-locked validation mechanism in the `@core` validator.
+
+### 📚 Documentation & Ecosystem
+- **SSR Hydration Fixes**: Fixed `Temporal is not defined` crashes during VitePress SSR builds by enforcing global polyfill initialization in `.vitepress/config.ts`.
+- **Navigation Enhancements**: Integrated the new Internationalization (`tempo.locale.md`) guides into the primary VitePress sidebar.
+- **MathPlugin Removal**: Removed the heavy `math: true` Markdown plugin from the documentation pipeline and migrated all computational complexity notations (e.g., `O(1)`) to standard inline code to prevent Vue compiler crashes and reduce client bundle sizes.
+
+### Added
+- **Multi-lingual Parsing**: The `locale` configuration property now officially accepts an array of strings (`string | string[]`). This enables the `ParseModule` to intelligently extract terminology from multiple languages simultaneously, generating a single, high-performance, deduplicated RegExp engine capable of parsing dates from any of the specified locales interchangeably.
+- **O(1) Locale Traceability**: Upgraded the internal dictionary architecture so that `monthMap` and `weekdayMap` store strict objects `{ value, locale }` instead of raw numeric indices. This allows the Normalizer to resolve the winning language of a matched token in pure `O(1)` time without any expensive Regex sub-capture scanning, automatically injecting the originating `locale` into the `t.Parse.result` debugging array!
+- **Intl.DateTimeFormatOptions Passthrough**: The `.format()` method now officially supports passing a native `Intl.DateTimeFormatOptions` object. This provides a highly flexible, "humanized" wrapper around the rigid `Temporal` API for complex cultural formatting (e.g. Arabic, Japanese Reiwa).
+- **Native Intl Delegation Support**: The formatting engine now explicitly attempts to use the high-performance, memoized `getDTF` instance to support V8's upcoming native `Temporal` support in `Intl.DateTimeFormat`.
+- **BigInt Overload for Epoch Nanoseconds**: Implemented a `BigIntPattern` registry and resolution logic to guarantee that the `{nano}` token (epoch nanoseconds) correctly coerces to and returns a precision-preserving `BigInt` instead of a string, as it vastly exceeds `Number.MAX_SAFE_INTEGER`.
+
+### Changed
+- **Parser Map Safety**: To support multi-lingual lexing securely, the internal reverse-lookup `localeMap` has been architecturally split into distinct `monthMap` and `weekdayMap` dictionaries. This eliminates the risk of cross-locale abbreviation collisions (e.g., if "mai" is a month in one language but a weekday in another), guaranteeing completely safe parsing determinism.
+
+### Fixed
+- **Polyfill RangeError Bypassing**: Implemented a defensive stripping mechanism that intercepts and deletes `timeZone` and `calendar` constraints from the `options` object when falling back to the `ZonedDateTime.prototype.toLocaleString()` polyfill. Additionally, wrapped `withTimeZone` and `withCalendar` shifts in `try/catch` blocks to gracefully bypass invalid configurations and safely fall through to the native Intl fallback without crashing the formatter.
+- **Strict Numeric Output Evaluation**: Fixed a bug where `{nano}` was bypassing the precision-preserving `ifNumeric` coercion due to an evaluation gap in the generic numeric-pattern detector.
+
+## [3.1.1] - 2026-06-14
+
+### Added
+- **Tokens & Modifiers**: Added `{h12}` for 12-hour clock output with automatic meridiem injection, `{cal}` for calendar system resolution, and the `:raw` modifier for stripping leading zeros and suppressing auto-meridiem.
+- **Dynamic Format Options**: The `.format()` method on `Tempo` instances now natively accepts an optional configuration object (e.g., `{ locale: 'fr-FR' }`) as its second argument, aligning its signature with native `Intl` overrides.
+
+### Changed
+- **Automatic Meridiem Injection**: Rewritten to derive modifiers directly from the matched `{h12}` or `{HH}` token, properly applying casing and placement.
+- **Zero-Padded Documentation**: Refined format token documentation to explicitly refer to fixed-length representations as "Zero-padded" (e.g., "Zero-padded Month"), clarifying the exact behavior of the `:raw` modifier.
+- **Strict ISO Vocabulary**: Updated documentation for `{dow}`, `{ww}`, and `{yw}` to explicitly designate them as ISO standards, removing ambiguity with native JavaScript `Date` offsets.
+
+## [3.1.0] - 2026-06-13
+
+### Added
+- `registry: { formats, locales }` namespaces to `Tempo.init()` and `Tempo` instance configurations.
+- `format: { localize }` namespace to options for toggling localizing formats.
+- `Tempo.registry` static accessor for retrieving the active registry configurations.
+- **Chained Formatting Modifiers**: Introduced a powerful format modifier engine (e.g. `{mon:locale:upper}`) allowing dynamic casing (`:upper`, `:lower`, `:title`), ordinal suffixes (`:ord`), and deep localization (`:locale`) directly within template strings.
+- **Global LOCALE Registry**: Implemented a global `STATE.LOCALE` registry (`Tempo.init({ locale: 'fr-FR', registry: { locales: { ... } } })`) to provide centralized, context-aware translations.
+- **Auto-Localization**: Added a `format: { localize: true }` global configuration flag that automatically applies the `:locale` modifier to all formatting tokens behind the scenes.
+- **Internationalized Parsing**: Implemented robust localized parsing capabilities natively into Tempo. By opting in via `Tempo.init({ locale: 'fr-FR', parse: { localize: true } })`, Tempo automatically registers localized variants for months, weekdays, and relative terms (yesterday, today, tomorrow) based on your configured `locale`. This engine dynamically strips accents (so "février" and "fevrier" both match safely), ensuring resilient fuzzy-matching for user input out-of-the-box.
+
+### Deprecated
+- Top-level `formats` configuration key. Use `registry: { formats: ... }` instead.
+- `Tempo.formats` static accessor. Use `Tempo.registry.formats` instead.
+
+### Changed
+- **Optimized Intl Instantiation**: Refactored `Intl.DateTimeFormat` and `Intl.RelativeTimeFormat` creation using memoized helpers (`getDTF`, `getRTF`) across the formatting engine, drastically reducing object instantiation overhead during rapid format evaluations.
+- **Term Localization Precedence**: Upgraded the Term formatting resolution pipeline to support falling back across a strict precedence: Global Registry > Plugin Bundled Dictionary > term's existing label/value.
+- **Plugin Localization Capabilities**: Refactored the `TimeOfDay` plugin (and underlying range resolution logic) to natively bundle and evaluate custom `locale` objects across languages without requiring external overrides in order to demonstrate the new `parse: { localize: true }` capability.
 
 ## [3.0.2] - 2026-06-12
 
+### Security
+- **Sandbox Isolation (Premium)**: Fixed a validation leakage where premium plugins inside Sandboxes (`Tempo.create()`) inadvertently validated against the global execution environment. Plugin wrappers now dynamically intercept their `this` context via the prototype chain to guarantee strict License Key isolation per Sandbox instance.
+- **Per-Scope Expirations (Premium)**: Hardened the commercial validation engine to fully support "One Master Key" architectures. The engine now rapidly evaluates Unix `exp` boundaries at the individual scope level, supplementing the top-level JWT validation.
+
+## [3.0.1] - 2026-06-11
+
+### Changed
+- **Node Engine Constraint**: Clarified the Node.js requirement in `package.json` to `>=20.0.0`. While Tempo supports native `Temporal` in Node 22+, due to known instabilities in Node 22.0.x native Temporal, using Node 20+ with a polyfill like `@js-temporal/polyfill` is highly recommended.
+- **Browser Compatibility Checks**: Established a fully automated headless browser test suite (`@vitest/browser`) using WebdriverIO to guarantee that Granular ESM bundles resolve dynamically imported relative paths natively. Browser compatibility is now enforced as a `prepublishOnly` lifecycle gate.
+
 ### Fixed
-- **Plugin Licensing Engine**: Resolved race conditions and dynamic module resolution issues that caused CI test failures during Premium license validation.
-- **Dependency Compatibility**: Removed the dependency on `isNumber` within the `@core` licensing engine to ensure backward compatibility and prevent `TypeError`s when validating licenses against earlier plugin environments.
+- **Term Scope Isolation**: Fixed a bug where the `Tempo.terms` getter would inappropriately sweep all licensed scopes (including modules and extensions like `ticker`) into the Terms array. `Tempo.terms` now strictly returns only the registered, queryable Term plugins, while preserving raw scopes in `Tempo.license.scopes`.
+- **Background Validation Leaks**: Resolved asynchronous test leakage in the licensing test suites by ensuring all background cryptographic verification pledges are explicitly awaited during test teardown.
+- **TimelineTerm Naming Collision**: Renamed the `TimelineTerm` shorthand key (`per`) and scope (`period`) to `tod` and `timeOfDay` respectively to definitively resolve semantic collisions with the native layout Period alias engine (`{per}`).
+- **Registry Type Completeness**: Added `start` and `end` boundary types (as `Tempo` instances) to the `TempoTermRegistry` augmentations for all core terms (`quarter`, `season`, `zodiac`, `timeOfDay`), correctly reflecting the dynamic boundaries injected by the resolver.
+- **Zodiac Typings**: Tightened the `yinYang` property typing in the `ZodiacTerm` payload from `string` to a literal union `'Yin' | 'Yang'`.
+
+### Security
+- **Immutability Hardening**: Locked down Term plugin registration (`defineTerm`) using native `deepFreeze()` and Term boundary ranges (`defineRange`) using the `secure()` Proxy. This guarantees that internal boundaries and metadata cannot be inadvertently mutated by rogue extensions or user code.
+
+### Standardization
+- **Semantic Casing Standardization**: Standardized Term ranges (e.g. `TimelineTerm`, `SeasonTerm`, `QuarterTerm`) to explicitly use CapInit (TitleCase) for their presentational `key` identifiers (e.g., `'Midnight'`, `'Morning'`) while explicitly retaining lowercase representations for internal `scope` and `group` variables.
 
 ## [3.0.0] - 2026-06-07
 
+### Changed (Breaking)
+- **Ticker Extraction**: The `TickerModule` has been extracted from the core Tempo library into a standalone, licensed premium plugin (`@magmacomputing/tempo-plugin-ticker`). It is no longer bundled with the open-source distribution. 
+- **ISO Getter Precision**: The `.iso` property getter has been upgraded from native `Date.toISOString()` to Temporal's `Instant.toString()`. This provides full ISO 8601 nanosecond precision and omits fractional seconds when they evaluate to exactly zero. 
+- **Deprecated Boolean Debug Flag**: The `debug` configuration property no longer accepts `boolean` values (`true`/`false`). It has been strictly typed to accept numeric verbosity levels (matching the `LOG` enum) or lowercase string labels (e.g., `'trace'`, `'info'`).
+- **Internationalization Naming**: The legacy `intl.relativeTime` configuration object has been removed to align with ECMAScript standards. Please migrate to `intl.relativeTimeFormat`.
+- **Legacy Discovery Keys**: Dropped support for the legacy `term` and `plugin` initialization options in favor of strict schema adherence (use `terms` and `plugins` instead for consistency).
+
+### Changed (Architecture)
+- **Configuration Parsing Unification**: Refactored the core configuration pipeline by routing `Tempo.init()`, `Tempo.extend()`, and `Tempo.create()` through a unified `[$setDiscovery]` parser. This removes 50 lines of duplicate parsing logic and significantly improves architectural consistency.
+- **Feature-Complete Sandboxes**: Sandboxes instantiated via `Tempo.create()` now process their full `options.discovery` payload through the unified parser. This enables sandboxes to safely inherit and isolate localized plugins, custom formats, timeZones, and ignore rules, rather than just `monthDay` inheritance.
+
 ### Added
-- **Tempo Registry Integration**: Moving towards deeper, centralized integration with the Tempo Registry infrastructure to streamline community and proprietary plugin distribution.
-- **Modernized Duration Engine**: Introduced the chainable `.balance()` method to intelligently normalize temporal intervals (e.g., converting 365 days seamlessly into 1 year).
-- **Duration Formatting**: Added a localized `.format()` method utilizing `Intl.DurationFormat` (with `Intl.NumberFormat` fallback support) for plural-aware, human-readable duration strings. Added `durationFormat` and `numberFormat` into `IntlOptions` to support global, instance-level, and method-level formatting overrides.
-- **Enterprise Plugins Scaffolding**: Initial architectural scaffolding for upcoming enterprise `Cron` and `SLA` plugins, including a performant asynchronous `preloadHolidays` pattern for synchronous holiday-aware calculations.
+- **Developer Benchmarks**: Introduced the `BenchmarkModule`, a decoupled utility for stress-testing and benchmarking Tempo parsing speeds and memory overhead against custom production datasets in any environment (Node.js or Browser).
+- **Compact Date Tokens**: Added `{dmy}`, `{mdy}`, and `{ymd}` to the `FormatModule` for generating 8-digit compact date strings (e.g. `24102026`).
+- **Ordinal Format Tokens**: Added uppercase `{DAY}`, `{WW}`, and `{MM}` to the `FormatModule` which generate the ordinal string representation (e.g. `24th`, `1st`, `2nd`).
+- **Compact Time Rename**: Renamed the `{hhmiss}` token to `{hms}` in the `FormatModule` for consistency with other token styles.
+- **Native Cryptographic Primitives**: Added lightweight, tree-shakeable `cipher` and `webToken` modules to `@magmacomputing/tempo/library` to support native Web Crypto JWS validation across the ecosystem, enabling the removal of bulky third-party dependencies (like `jose`) in down-stream plugins.
+### Migration
+- If you used `Tempo.ticker()`, you must now install `@magmacomputing/tempo-plugin-ticker` and register it. A migration stub is currently left in place that will throw a runtime error with directions to the Tempo Registry to obtain your free license key.
+
+## [2.11.2] - 2026-05-27
 
 ### Changed
-- **Ticker Plugin Licensing**: The `Ticker` plugin has transitioned to a licensed model. It remains completely free to use, but now requires validation via the Tempo Registry ecosystem.
-- **Robust License Validation**: Hardened runtime integrity for Tempo Pro plugins to enhance state security and prevent tampering.
-- **Edition Boundaries**: Added proactive runtime warnings for unlicensed attempts, establishing strict boundaries between the Community and Proprietary editions.
-- **Extension Resolution**: Stabilized module resolution for plugins by migrating to `definePlugin` and correcting internal export paths.
-- **Logging Subsystem Decoupling**: Fully decoupled the internal parsing and error boundaries from the legacy `Logify` architecture, enabling zero-cost trace instrumentation.
-- **Diagnostic Consistency**: Standardized fatal exceptions by introducing the `TempoError` class for internal invariant violations, and unified all console output through the centralized diagnostic bus (`logWarn`).
-- **Documentation**: Clarified API behavior for the Duration engine (especially `.since()` return types) and relative time math. Improved visibility and navigation for the Tempo License Registry and installation guides.
+- **Module Resolution Stability**: Removed `"development"` conditions from the `packages/tempo/package.json` `imports` map. This prevents downstream test runners (like Vitest) from attempting to resolve internal `#tempo` imports to `.ts` source files when importing the published NPM package, resolving `ERR_MODULE_NOT_FOUND` and `ERR_UNSUPPORTED_NODE_MODULES_TYPE_STRIPPING` errors. Consumers now gracefully fall back to compiled `.js` files in `dist/`.
+
+## [2.11.1] - 2026-05-26
+
+### Added
+- **ISO 8601 Convenience Getter**: Added the `.iso` getter to `Tempo` instances to provide a fast, familiar, and UTC-safe mechanism for retrieving the standard ISO 8601 string representation (analogous to `Date.toISOString()`).
+- **Type Utilities Export**: Exported `KeyOf`, `ValueOf`, `OwnOf`, and `EntryOf` type utilities in `library.index.ts` to provide cleaner TypeScript typing for downstream consumers utilizing `enumify`.
 
 ### Fixed
-- **Module & Key Collisions**: Fixed registry authentication double-initialization bugs and terminal key registration collisions (e.g., the `[Tempo#extend] Term collision on key: "qtr"` error).
-- **Ticker Plugin Stabilization**: Resolved lifecycle issues and nailed down the Ticker plugin architecture and API behavior.
+- **Build Pipeline Path Resolution**: Fixed a critical path-resolution bug in the `resolve-types.ts` script where `library.index.d.ts` was incorrectly identified as being inside the `lib/` directory. This ensures proper `.d.ts` generation and restores JSDoc/typings for downstream consumers.
+- **Documentation Domains**: Updated all premium extension documentation (`tempo.license.md`) and internal plugins to use the centralized `registry.magmacomputing.com.au` domain for license verification and the UI portal.
 
 ## [2.11.0] - 2026-05-25
 
+### Added
+- **Duration Mathematics**: Introduced the `.balance()` method to `Tempo.Duration` objects to allow intelligent mathematical roll-up of duration units (e.g., converting 365 days into 1 year), with support for both strict calendar math and nominal overrides (`{ nominal: true }`).
+- **Duration Formatting**: Introduced the `.format()` method to `Tempo.Duration` objects. This uses a shared, memoized `#library` implementation of `Intl.NumberFormat` to generate highly localized, plural-aware duration strings with excellent performance and robust cross-environment execution (no `navigator` dependencies).
+- **Cascading Configuration**: Added `numberFormat` to the `IntlOptions` interface, allowing developers to set global formatting defaults (like `unitDisplay: 'short'`) via `Tempo.init()` that seamlessly cascade down to all `.format()` calls.
+
 ### Fixed
-- **Open Core Build Fallback**: Updated the `build:resolve` script to gracefully fallback to Open Core licensing types when the proprietary `@core` module is unavailable, resolving CI build failures in public GitHub Actions environments.
+- **Parsing**: Resolved an engine edge-case where combining relative weekday modifiers with string-based period aliases (e.g., `<3 Wed afternoon`) would cause the parser to prematurely abort the relative offset, instead applying the period to the current system date.
+  
+## [2.10.1] - 2026-05-22
+
+### Added
+- **Build Pipeline Visuals**: Upgraded the `rollup.config.js` build output with high-visibility, color-coded ANSI banners to clearly distinguish between `PREMIUM` and `COMMUNITY` build targets.
+
+### Changed
+- **Discovery Architecture**: Deprecated and purged the legacy `__TEMPO_DISCOVERY__` global discovery approach in favor of a strict `TEMPO_LICENSE_KEY` and Symbol-based registry pipeline.
+- **Security Hardening**: Redacted the raw JWT key from the public `Tempo.license` snapshot to prevent accidental exposure of credentials in debug logs.
 
+### Fixed
+- **License Snapshot Resilience**: Implemented a safety guard in `Tempo.license` to normalize `raw.scopes` before iteration, eliminating potential runtime exceptions when scopes are absent.
+- **Cross-Platform Build Stability**: Updated the `resolve-types.ts` build script to utilize Node's native `fileURLToPath` for deterministic `__dirname` resolution across all operating systems.
+- **Local Dev Extensibility**: Allowed `LIC_SRC_DIR` to be overridden via environment variables in the type resolution script, supporting customized development workflows while maintaining strict production fallbacks.
+  
 ## [2.10.0] - 2026-05-11
 
 ### Added
-- **Licensing Architecture Preparation**: Initial work to support licensed plugins and features.
+- **Licensing Architecture**: Implemented a standalone "No-Op" licensing engine (`support.license.ts`) in the public core. This ensures the repository is 100% buildable and testable by the community without private dependencies.
+- **Automatic Premium Injection**: Optimized the build pipeline (Rollup/Vitest) to automatically detect and inject the proprietary licensing engine from a side-by-side repository during official builds.
+- **Portable Encoding**: Migrated `base64Encode` to the shared library for universal, environment-agnostic token handling.
 
 ### Changed
+- **Hardened Licensing Resolution**: Updated the term resolution pipeline with a dual-identity race-condition guard (JTI + Key) and a late-binding resolution guard to securely handle `Pending` to `Revoked` state transitions.
+- **Decoupled CI Resolution**: Eliminated the need for private registries or stubs in GitHub Actions by utilizing the internal No-Op engine for standard test runs.
 - **Term Collision Enforcement**: Term plugin registration now throws a fatal error on naming collisions (key/scope) to prevent silent configuration failures.
 
 ## [2.9.3] - 2026-05-11
 
 ### Added
-- **Fractional Resolution**: Numeric inputs now support fractional components with nanosecond precision using BigInt math.
-- **Hardened AliasContext**: Improved chainable context for functional aliases with full API parity.
-- **Epoch Support**: Enhanced detection for 9-10 digit Epoch timestamps.
+- **Generalized Fractional Resolution**: Numeric inputs (`Number`, `BigInt`) now support fractional components across all units (`ss`, `ms`, `us`, `ns`) with nanosecond precision. The resolution engine now utilizes absolute BigInt math to ensure deterministic results regardless of sign.
+- **Hardened AliasContext Interface**: Introduced a strongly-typed, chainable context (`this`) for functional aliases, providing API parity with the `Tempo` class. This includes full support for `yy`, `mm`, `dd`, `hh`, `mi`, `ss`, `tz`, `cal`, and `config` properties.
+- **ISOString Branded Type**: Added a branded `ISOString` type for clearer representation of `ZonedDateTime` ISO-8601 strings, improving type safety across the library's internal and public APIs.
+- **Shorter Epoch Support**: Numeric strings with 9-10 digits are now correctly classified as Epoch timestamps when a non-default unit (e.g., `'ss'`) is configured. This enables parsing of second-based timestamps like `946684800` without requiring manual padding.
+
+### Changed
+- **Dependency Refresh**: Updated Temporal Polyfill to 0.2.1, ensuring a more stable and secure development environment.
+- **Unit Preference Enforcement**: Consolidated numeric resolution logic in `engine.composer.ts` to strictly enforce configured `unit` preferences ('ss', 'ms', 'us', 'ns') for both `Number` and `BigInt` types.
+- **Lexer Prefix Reliability**: Optimized and hardened the `prefix()` helper in `engine.lexer.ts` to provide faster, type-safe string transformations for weekday and month formatting.
+
+### Fixed
+- **State Mutation Safety**: Refactored the internal parsing engine to eliminate side-effect mutations on the global configuration state during resolution. This ensures that `parse()` results are deterministic and do not leak transient metadata into subsequent calls.
+- **Priority-Based Configuration**: Hardened the configuration resolution in `engine.composer.ts` to strictly prioritize explicit caller overrides (e.g., `timeZone`, `calendar`) over metadata derived from input objects, ensuring that methods like `.toDateTime(zdt, { timeZone: 'UTC' })` always honor the provided override.
+- **Registry Initialization Resilience**: Updated the `onRegistryReset` hook in `tempo.class.ts` to automatically re-hydrate computed snippets (e.g., `tomorrow`, `noon`) after a registry reset. This resolves matching failures in testing environments where registries are cleared between runs.
+- **withState Wrapper Hardening**: Fixed an unwrapping bug in the `withState` utility that caused standalone `parse()` calls to return internal `TypeValue` wrappers instead of raw `ZonedDateTime` results when passed an explicit state object.
+- **Numeric Validation Ordering**: Reordered the resolution logic in `engine.composer.ts` to ensure `NaN` and non-finite numbers are caught before type conversion, preventing native `RangeError` crashes.
+- **Parser Epoch Short-circuit**: Refined the epoch detection in `module.parse.ts` to correctly identify all fractional numbers as timestamps, bypassing the layout engine and preventing "Unknown Term" resolution errors.
+- **Functional Alias Property Parity**: Added missing `year`, `month`, and `day` aliases to the `AliasContext` (mapped to `yy`, `mm`, `dd`) to ensure compatibility with standard `Tempo` getters.
+- **Timestamp Configuration Persistence**: Fixed configuration propagation by ensuring `timeStamp` is explicitly handled within `extendState` in `support.init.ts` for consistent state persistence across Tempo instances.
+- **Epoch Parsing Precedence**: Implemented a short-circuit in `parseLayout` to prioritize epoch interpretation for large numeric inputs, preventing their misidentification as layout patterns.
+- **Normalizer Memory Management**: Resolved state leakage in `engine.normalizer.ts` by ensuring alias keys are correctly cleaned up in the `resolvingKeys` set via `try/finally` blocks.
+- **ZonedDateTime Mutation Order**: Fixed `ZonedDateTime` mutation ordering in `module.parse.ts` to ensure time zone and calendar application precedes wall-clock property updates, preventing incorrect wall-clock values during zone shifts.
+- **Type Safety Hardening**: Eliminated DOM interface collisions in `tempo.type.ts` by correcting `PluginContainer` inheritance, improving type safety and preventing namespace pollution.
+- **Documentation Build Stability**: Stabilized the documentation build environment by resolving peer dependency resolution errors between VitePress and `markdown-it-mathjax3`.
+
+## [2.9.2] - 2026-05-08
+
+### Added
+- **Resilient ID Extraction**: Unified `timeZoneId` and `calendarId` extraction into a single spec-resilient helper `getTemporalIds`. This ensures 100% compatibility across both spec-final and Node.js V8 harmony environments by resolving nested property drift (`timeZone.id` vs `timeZoneId`).
+- **Identity-Based Layout Resolution**: Hardened `resolveLayoutClassificationOrder` to support identity-based symbol lookups. This ensures that tokens without descriptions or aliases (such as raw symbols) can be correctly prioritized in preferred layout ordering.
+- **Named Capture for Separators**: Updated the default `{sep}` snippet to use a named capture group `(?<sep>...)`, improving the inspectability of generated regex patterns.
 
+### Changed
+- **Non-Recursive Bootstrap**: Hardened the `toNow()` lifecycle and `today` alias to safely access local configuration without triggering circular parsing dependencies.
+- **Modular Decompression**: Removed the redundant `parse.layout.ts` re-export module and consolidated all layout resolution logic into `engine.layout.ts`. Updated internal Specifiers and test-aliases to point to the new canonical home.
+- **Node.js Harmony Support**: Updated documentation to highlight native `Temporal` support in Node.js 20+ via the `--harmony-temporal` flag, reducing the need for external polyfills in modern server-side environments.
+
+### Fixed
+- **MasterGuard Validation**: Improved the `MasterGuard` scanner to correctly identify and reject whitespace-only strings by implementing explicit match tracking.
+- **Symbol Mapping Safety**: Fixed a potential `TypeError` in `AliasEngine` when mapping Symbols without descriptions by hardening the `wordsList` creation logic.
+- **Utility Security Hardening**: Refactored the `create<T>` and `setPatterns` utilities with robust prototype-shadowing guards. These improvements prevent `TypeError` crashes when interacting with null-prototype objects and guarantee `PatternCompiler` state isolation across concurrent Tempo instances.
+- **PatternCompiler Isolation**: Refactored `Tempo.regexp()` to guarantee `PatternCompiler` isolation per-state, preventing unintended cache leakage across inherited registries.
+- **UI Accessibility**: Updated documentation button styles to use theme variables, ensuring WCAG 2.1 contrast compliance (4.5:1) for all brand elements.
+- **RegExp Preview Accuracy**: Corrected the documentation example for `Tempo.regexp()` to accurately reflect the anchored outer capture group and unique named snippet expansions (`sep`, `sep_1`) produced by the engine.
+
+## [2.9.1] - 2026-05-07
+
+### Fixed
+- **Support Utility Consolidation**: Completed the rename and migration of internal support utilities to the `@packages/tempo/src/support/` directory.
+- **Pattern Compiler isolated test state**: Fixed state-leakage in `pattern_compiler_optimization.test.ts` by implementing `TempoRuntime.createScoped()` and `init({}, false)` within `beforeEach` hooks.
+
+## [2.9.0] - 2026-05-06
+  
+### Added
+- **Centralized Alias Architecture**: Finalized the migration to a unified `AliasEngine`. All event and period aliases are now managed through a centralized registry, providing a single source of truth across global and local contexts.
+- **Rich Alias Results**: Alias resolution now returns a structured `AliasResult` object containing exhaustive metadata, including the source (global/local), type (Event/Period), and specific resolution flags.
+- **Hardened Clock Snapping**: Standardized the resolution path for clock-like aliases (e.g. `8:00`). The engine now ensures absolute sub-second precision clearing (milliseconds, microseconds, and nanoseconds) when snapping to a time-string alias.
+- **Optimized Lifecycle Monitoring**: Implemented a version counter in the `AliasEngine`. Mutation operations now trigger a version increment, allowing `Tempo` instances to efficiently detect registry changes and rebuild internal regex patterns without expensive deep-cloning.
+  
+### Changed
+- **Parser Context Consolidation**: Extracted the "host" facade construction from the main parsing loop into a dedicated `getResolutionContext` helper, improving maintainability and reducing Parser complexity.
+- **Decoupled Term Registration**: Refactored `Tempo.extend` and term-based alias registration to bypass legacy raw registries, while maintaining backward compatibility via a mirrored metadata view.
+  
 ### Fixed
-- **Mutation Safety**: Eliminated side-effects on global configuration during parsing.
-- **Normalizer Memory**: Fixed state leakage in alias resolution.
+- **Documentation Server Stability**: Resolved VitePress 404 errors by correcting the `srcDir` configuration and implemented `srcExclude` to prevent build failures from dead links in non-documentation folders.

-- **Internal State Protection**: Hardened the `[sym.$Internal]()` accessor, making the underlying `zdt` read-only to guarantee instance immutability.
+- **Boundary Performance**: Optimized the term resolution loop to utilize `BigInt` nanosecond comparisons for all shifter logic (`>`, `<`, `next`, `prev`), ensuring deterministic behavior across complex fiscal and calendar boundaries.
+- **Fail-Fast Constructor**: Hardened the constructor guard to explicitly `throw` an `Error` when term-based mutation keys (`#`) are detected. This replaces the previous silent "invalid instance" return, ensuring developers catch improper syntax immediately.
+- **Config Merge Priority**: Refactored `Tempo.#setConfig` to read from persistent storage *before* applying provided options, ensuring that stored values are not unintentionally overwritten by transient defaults.
+- **Centralized Patterns**: Integrated the numeric string detection regex into the central `Match` registry in `tempo.default.ts`, removing hardcoded duplicates from the mutation module.

-- **Redundant State Removal**: Eliminated the unused global `STATE` constant from utilities to prevent potential cross-instance state leakage.
+- **Infinite Loop Resolution**: Resolved a critical regression where shorthand modifiers were leaking into range-keys, triggering infinite recursion during term mutation.
+- **Hemisphere Inference**: Fixed an initialization bug in `Tempo.init()` where the `sphere` configuration could be incorrectly overwritten or ignored during system-timezone evaluation.
+- **Shorthand Lexer Safety**: Hardened the lexer to strictly enforce Range-Key constraints (no reserved characters or leading digits), eliminating collisions between direction modifiers and repeat counts.

+- **Constructor Protection**: Implemented a strict guard against passing term-based mutation objects (`#`) directly to the `Tempo` constructor. The engine now explicitly rejects these inputs and directs users to the appropriate `.set()` or `.add()` methods for instance transformation.
+- **Unified Term Errors**: Centralized term-resolution error logic into a shared static helper, ensuring consistent "Helpful Hint" messaging for missing plugins across the constructor, mutation engine, and parser.
 
 ### Changed
-- **High-Precision Ticker**: Migrated `TickerPlugin` from `Date.now()` to `instant().epochMilliseconds`, ensuring consistent use of high-precision timing without legacy `Date` object dependencies.
-- **Test Performance**: Standardized the test suite on `vitest --pool=forks` to ensure deterministic execution of asynchronous ticker and generator tests.
-- **Vitest Upgrade Deferral**: Intentionally deferred the upgrade to Vitest 4.x and maintained version `^2.1.8`. The current Vitest 4 transformer (Oxc) does not yet support the Stage 3 (ECMAScript) decorators used extensively by this library's `@Immutable` and `Logify` utilities.
+- **Modular Hardening**: Hardened the core engine to strictly enforce `ZonedDateTime` types for all internal states. This prevents "Ghost Date" leaks and silent fallbacks to "Today" when input resolution fails in Core mode.
+- **Singular Path Refactor**: Standardized all internal and external paths, directories, and documentation to use the singular `plugin` and `term` form (e.g., `#tempo/plugin`, `@magmacomputing/tempo/term`).
+- **Auto-Lazy Precision**: Refined the "Zero-Cost" auto-lazy trigger to only fire for String inputs, ensuring that malformed Objects fail-fast during construction rather than deferring failures.
+- **Bulk Extension DX**: Rebuilt `Tempo.extend()` with intelligent rest-parameter support and restored high-level type overloads for improved IDE autocompletion and type-safety.
 
 ### Fixed
-- **Term Plugin Resolution**: Corrected package export mappings for term-based plugins in `package.json`, resolving module resolution errors in development and test environments.
-- **Numeric Word Parsing**: Fixed regressions in numeric word resolution (e.g., "eleven days hence") by ensuring registry synchronization during late-import scenarios.
+- **Build Stability**: Resolved type errors in the test suite (specifically `tempo_guard.test.ts`) that were triggering failures during project-referenced builds (`tsc -b`).
+- **Sync Normalization**: Fixed a regression where early-resolving inputs (like ISO strings) were bypassing final timezone and calendar normalization.

-## [2.0.0] (Internal) - 2026-03-30
+## [2.1.0] - 2026-04-11
 
 ### Added
-- **Zero-Cost Constructor**: Optimized the instantiation path to $O(1)$ by deferring all parsing and property registration until the first property access.
-- **Generic Lazy Delegator**: Introduced `getLazyDelegator` to standardize on-demand property discovery for `fmt` and `term` objects.
-- **Anchor-Aware Parsing**: Added native support for anchoring relative date strings (e.g., "next Friday") to a specific reference date via the `anchor` option.
-- **Timezone Safety**: Implemented graceful fallback to `UTC` (with a warning) for invalid IANA TimeZone IDs when `catch: true` is enabled.
-
-### Fixed
-- **Parsing Robustness**: Resolved 299/299 regressions in the core and plugin test suites.
-- **Immutability Performance**: Fixed `TypeError` during lazy discovery on secured instances by implementing defensive prototype-shadowing.
-
----
-
-## [1.3.0] - 2026-03-26
-
-### Added
-- **Reactive Registration Hook (`$Register`)**: Introduced a global reactive hook that allow plugins to automatically trigger `Tempo.init()` if they are imported after the main library. This resolves several "late import" edge cases in complex bundle environments.
-- **Strictly Typed Enums**: Refactored `tempo.enum.ts` with private `const` key arrays, restoring 100% strict type inference (no more `any`) while maintaining a clean, code-minimal declaration pattern.
-- **Dynamic Registry Mapping**: Implemented a centralized `REGISTRIES` map in `tempo.enum.ts`, providing a single point of change for all discoverable registries (`NUMBER`, `FORMAT`, `TIMEZONE`, etc.).
+- **TimeZone Offset Support**: Formally verified and documented support for `+HH:MM` and `-HH:MM` ISO-8601 fixed-offset strings in the `timeZone` configuration.
+- **Browser Reference Map**: Included a comprehensive [importmap.json](./importmap.json) in the package root to provide a standard mapping for bare module specifiers in browser environments.
 
 ### Changed
-- **Plugin Architecture Consolidation**: Centralized all core registration logic, symbols ($Tempo, $Plugins, $Register), and factory methods (`definePlugin`, `defineTerm`) into a single module at `packages/tempo/src/plugins/tempo.plugin.ts`.
-- **API Consistency**: Updated `Tempo.init()` to return `this` (the static class instance) to better support fluent chaining patterns (e.g., `Tempo.init({...}).extend(...)`).
-- **Circular Dependency Resolution**: Relocated term plugins and adopted a strict "import type" policy in the plugin layer to break core-plugin cycles and improve build stability.
+- **Modular Import Refactor**: Cleaned up the public API by removing the required `plugin/` component from sub-path imports. Plugins are now accessible directly via `@magmacomputing/tempo/ticker`, `@magmacomputing/tempo/duration`, etc.
+- **Configuration Mode**: Refactored the `lazy: boolean` option into a more semantic `mode: 'auto' | 'strict' | 'defer'` setting, offering better control over the Zero-Cost Constructor hydration strategy.
+- **Export Alignment**: Synchronized `package.json` `exports` with the recommended import-map and documentation snippets to ensure 1:1 parity between Node.js and Browser environments.
 
 ### Fixed
-- **Type-Safe Discovery Symbols**: Updated `BaseOptions` to natively support `symbol` as a discovery key, resolving "not assignable" errors across the test suite and production environments.
-- **Ticker Plugin Typing**: Resolved implicit `any` and reduction-type errors in the ticker plugin for better safety in strict mode.
-- **Weekday/Month Alignment**: Restored 1-based alignment (ISO 8601) for `WEEKDAY` and `MONTH` enums by ensuring `All`/`Everyday` placeholders remain at index 0.
+- **Documentation Clarity**: Updated all markdown guides (Ticker, Terms, Layout, etc.) to use verified import patterns and corrected various outdated configuration references.
 
 ---
 
-## [1.2.0] - 2026-03-23
-
-### Added
-- **Monorepo Migration**: Successfully transitioned to a unified monorepo structure, naming `packages/tempo` and `packages/library` as npm workspaces.
-- **Publishing Optimizations**: Integrated `prepublishOnly` build hooks and `files` whitelisting in `package.json` for leaner and more reliable NPM distribution.
-- **Enhanced Type Resolution**: Fixed `node` type definition errors in nested test environments by explicitly configuring `typeRoots`.
-
-### Changed
-- **Dependency Rationalization**: Consolidated `tslib` and `@js-temporal/polyfill` at the project root while preserving `tslib` as a runtime dependency for published packages.
-- **Plugin Loading Refactor**: Refactored `static load` into a unified, single-pass dispatch logic for handling Plugins, TermPlugins, and Discovery configurations robustly.
-
-## [1.1.0] - 2026-03-21
-
-### Added
-- **Plugin System (`Tempo.load`)**: Introduced a formal architecture for extending the `Tempo` class and prototype, allowing for modular feature injection (e.g., `TickerPlugin`).
-- **Auto-Plugin Discovery**: Plugins can now be automatically loaded via the `plugins` configuration in `Tempo.init()` or through the Global Discovery manifest (`Symbol.for($Tempo)`).
-- **Selective Immobility**: Enhanced the `@Immutable` decorator with a "Selective Immute" pattern. Core methods (including Symbols like `Symbol.dispose`) are now write-protected, while the class remains extensible for new plugins.
-- **Reactive Clock (Modularized)**: The `Tempo.ticker` logic has been extracted into an optional plugin available at `@magmacomputing/tempo/plugins/ticker`. This reduces core bundle size while offering high-performance Async Generators and countdown support.
-- **Symbol Protection**: Core identifiers are now safe from runtime hijacking, providing a robust security model for library consumers.
-
-### Changed
-- **Polyfill Decoupling**: Moved the `Temporal` API availability check to the core `Tempo` class, allowing standalone utilities to run in environments without `Temporal`.
-- **Type-Strict Reflection**: Updated internal reflection tools to use `ownEntries()` for cleaner property descriptor management.
-- **Documentation Overhaul**: Updated all technical guides to reflect the modular, plugin-based architecture.
-
-## [1.0.8] - 2026-03-19
+## [2.0.1] - 2026-04-03
 
 ### Added
-- **Numeric Pattern Inference**: Corrected `Formats` and `Format` types to ensure numeric patterns (like `yearMonthDay`) are correctly inferred as `number` while preserving enum-like functionality for the format registry.
-- **Layout Patterns Guide**: Created a new technical guide `doc/tempo.layout.md` for describing Tempo services through custom layout/snippet building.
-- **Enum Type Flexibility**: Loosened TypeScript constraints on `enumify` objects. The `count()` method now returns a standard `number`, and iteration callbacks (`forEach`, `filter`, `map`) now accept a generic `Enum.wrap<any>`, resolving assignability issues in complex configurations like `Tempo.Config`.
-- **Custom Global Formats**: Introduced support for defining custom format layouts via Global Discovery (`Symbol.for($Tempo)`), making them available across all instances.
-- **Type Safety Refinement**: Significantly enhanced the `Tempo` class by removing redundant `as any` casts, particularly in `#parse` and timezone handling, achieved through better destructuring and explicit string resolution.
-- **Modern Syntax Adoption**: Updated the codebase to use `Object.getOwn()` instead of legacy `Object.prototype.hasOwnProperty.call()` for cleaner and more modern property checks.
-
-### Changed
-- **Core Simplification ($Base Removal)**: Removed the `$Base` symbol and its termination logic from `reflection.library.ts`. This simplifies prototype chain traversal across the library, as boundary protection is no longer required following the `config` getter refactor and existing enumerable property filtering for Enums.
-- **Constant Modernization**: Renamed and deprecated `Tempo.TIME` and `Tempo.TIMES` in favor of more semantic `Tempo.DURATION` and `Tempo.DURATIONS`, improving readability and consistency with internal logic.
-- **Enum Extension Optimization**: Refactored `Enum.extend` to support deep prototype chains (up to 50 levels) and fixed a critical boundary bug where root Enum data was being excluded from child extensions.
-- **Proxy Trap Performance**: Optimized `toJSON` and `$Inspect` traps in `proxify` to prevent unnecessary prototype chain traversal. The traps now prioritize checking for own properties, significantly improving performance and preventing recursion during serialization.
-- **Term Traversal Logic**: Unified prototype traversal by introducing a shared `$Base` symbol to terminate chain climbing, improving both performance and collision resistance.
-- **Node.js Custom Inspection**: Standardized the Node.js custom inspection symbol as `$Inspect` in the reflection library and updated `Tempo` and `Enumify` for consistent console formatting.
-- **Stealth Proxy for terms**: Implemented a "Stealth Proxy" for the `term` accessor to provide a flat, iterable object view of resolved terms across Node.js and Browser environments while preserving lazy resolution.
-- **Term Getters Performance**: Refactored `#setTerm` logic to use prototype shadowing (`Object.create`), improving performance and reducing overhead.
-- **Strict Global Discovery**: Standardized the global configuration mechanism by removing legacy `TempoOptions` support and strictly enforcing the `Tempo.Discovery` contract.
-- **Enumify Extend**: Refactored the internal `extend` utility within `enumify` for improved maintainability.
-- **Parsing Reorganization**: Adjusted the `#parse` method to resolve `tz` and `cal` identifiers *after* configuration updates, ensuring internal state always reflects the most current settings.
-
-### Fixed
-- **Decorator Compatibility**: Resolved nominal typing issues in `registerTerms` by loosening internal constraints, enabling seamless synchronization with projects using Stage 3 decorators (like `whiteLibrary`).
-- **Enum Boundary Bug**: Corrected the logic in `ownEntries` to ensure that root Enum entries (marked with `$Base`) are correctly collected during full-chain resolution.
-- **Getter Handling in Extensions**: Fixed a regression in `reflection.library.ts` where properties with getters were being incorrectly unwrapped; they are now accessed directly to ensure proper execution.
-- **Timezone Round-trip Restoration**: Fully resolved critical serialization regressions by updating `#setConfig` to recursively handle the `config` property during revival.
-- **Instance Timezone Integrity**: Restored the safe update to `#local.config.timeZone` in `#parseZone`, ensuring internal getters stay in sync with date-time strings without clobbering initial state.
-- **String Handling Cleanup**: Removed redundant `String()` wraps in regex group parsing and mutation logic where types were already guaranteed.
-
-## [1.0.7] - 2026-03-14
-
-### Added
-- **`toPlain...` Methods**: Added `toPlainDate()`, `toPlainTime()`, and `toPlainDateTime()` helper methods to the `Tempo` class for easier extraction of specific `Temporal` components.
-- **Argument Flexibility**: Enhanced `.set()` and `.add()` to accept either a date-time payload or an options object as the first argument, improving developer ergonomics.
-- **API Reference**: Created `doc/tempo.api.md`, a comprehensive technical guide covering all static and instance API entrypoints, signatures, and properties.
-- **TypeScript Types**: Created `doc/tempo.types.md` as a detailed reference for all core namespace types.
-- **Regression Tests**: Added `test/issue-fixes.test.ts` to permanently cover relative events, timezone brackets, and storage precedence.
+- **Ticker Stability Guard**: Implemented a 10,000-iteration safety break in `resolveTermShift` to prevent infinite loops when resolving malformed or non-advancing custom terms.
+- **Unified Diagnostics (`Logify`)**: Integrated the `Logify` utility into core internal classes for standardized `debug`, `catch`, and `silent` mode support.
 
 ### Changed
-- **Performance Optimization**: Switched Vitest to `--pool=forks` and refactored internal iteration in `.set()` and `.add()` to resolve test runner hangs during complex parsing.
-- **Relative Events**: Refactored `now`, `today`, `tomorrow`, and `yesterday` to be relative to the specific `Tempo` instance. Date-based events now use `toPlainDate()` for improved parsing robustness.
-- **Config Precedence**: Established and documented a reliable precedence order: Metadata < Defaults < Storage < Discovery < Global Init < Instance.
-- **Config Privacy**: Explicitly excluded the internal `anchor` property from public configuration to prevent developer confusion.
-- **Cleanup**: Removed obsolete `rdt` (recent date) snippet logic as it is fully superseded by smart event aliases (functions).
-- **Storage Logic**: Consolidated persistence merging into `#setConfig`, ensuring storage values correctly act as defaults.
-- **`toInstant` / `toDateTime` Getters**: Enhanced getters to prioritize the instance's underlying value while providing robust fallbacks to system "now" (including safe handling of uninitialized timezones).
+- **High-Precision Ticker**: Migrated `TickerPlugin` from `Date.now()` to `instant().epochMilliseconds`, ensuring consistent use of high-precision timing without legacy `Date` object dependencies.
+- **Test Performance**: Standardized the test suite on `vitest --pool=forks` to ensure deterministic execution of asynchronous ticker and generator tests.
 
 ### Fixed
-- **Timezone Round-trip**: Resolved a critical bug where timezone information was lost when reviving Tempo instances from JSON (serialization/deserialization).
-- **Timezone Bracket Parsing**: Resolved an issue where bracketed timezones were ignored or incorrectly overridden by offsets.
-- **Mutation Safety**: Fixed `TypeError: Cannot add property` in `#result` when performing operations on instances decorated with `@Immutable` by ensuring internal state is handled safely.
-- **Relative Event Drifting**: Fixed a bug where events like 'yesterday' were incorrectly calculated based on the run-date instead of the `Tempo` instance state.
-- **Storage Merge Bug**: Corrected an issue where explicit options were being clobbered by storage values.
-
-## [1.0.6] - 2026-03-12
-
-### Added
-- **API Reference**: Created `doc/tempo.api.md`, a comprehensive technical guide covering all static and instance API entrypoints, signatures, and properties.
-- **Node.js Support**: Added explicit server-side usage instructions and code examples to `README.md` and `doc/Tempo.md`.
-- **`{wy}` Token & Getter**: Introduced the `{wy}` formatting token and a corresponding public `wy` getter for the 4-digit ISO week-numbering year.
-
-### Changed
-- **Config Documentation**: Refactored `doc/tempo.config.md` to follow technical precedence (Persistence > Discovery > Global > Instance).
-- **Doc Cross-Linking**: Standardized documentation navigation by converting all textual cross-references into clickable markdown links.
-- **Precision Glossaries**: Refined documentation in `vision.md` and `comparison.md` to specify "meteorological seasons" and "zodiac signs".
-- **Token Renaming**: Renamed `{isoy}` to `{wy}` across the library, tests, and documentation for improved semantic clarity.
+- **Ticker Async Stability**: Resolved hangs in async generators (`for await...of`) by implementing a `Pledge`-based waiter resolution mechanism that guarantees immediate termination upon `stop()`, `return()`, or `throw()`.
+- **Ticker Pulse Synchronization**: Corrected pulse counts for both listeners and generators ($N$ pulses for `limit: N`); ensured `limit: 0` is strictly honored as zero pulses.
+- **Ticker Cold-Start**: Fixed an issue where tickers created without an initial callback would remain idle even after listeners were attached; extracted `#bootstrap()` to ensure the scheduler starts correctly on the first listener registration.
+- **Parsing Engine Optimization**: Refactored `Tempo.#setPatterns` to optimize pattern generation and avoid redundant global guard rebuilds, significantly improving performance for local/one-off parser instances.
+- **Local Layout Stability**: Fixed a bug where custom layout literals in local instances were being destroyed during state synchronization.
+- **Registry Protection**: Hardened `registryUpdate` to safely handle non-proxied or missing targets, preventing potential crashes during late-import plugin registration.
+- **Term Plugin Resolution**: Corrected package export mappings for term-based plugins in `package.json`, resolving module resolution errors in development and test environments.
+- **Numeric Word Parsing**: Fixed regressions in numeric word resolution (e.g., "eleven days hence") by ensuring registry synchronization during late-import scenarios.
 
-### Fixed
-- **ISO Week Logic**: Refined `wy` and `yyww` formatting logic to correctly handle boundary cases between years.
-- **Global Discovery Trace**: Improved trace logging visibility when `debug: true` is enabled.
+---
 
-## [1.0.5] - 2026-03-10
+## [2.0.0] - 2026-03-30
 
 ### Added
-- **GitHub Sponsors**: Integrated `FUNDING.yml` and added sponsorship links to `README.md`.
-- **Commercial Support**: Added `doc/commercial.md` outlining consulting and priority support options.
-- **Term Registration**: Implemented a new functional registration system for `Tempo.terms` to resolve circular dependencies.
+- **Zero-Cost Constructor**: Optimized the instantiation path to $O(1)$ by deferring all parsing and property registration until the first property access.
+- **Generic Lazy Delegator**: Introduced `getLazyDelegator` in `proxy.library.ts` to standardize on-demand property discovery for `fmt` and `term` objects.
+- **Improved Immutability**: Enhanced `@Immutable` and `secure()` protections that safely handle lazy evaluation on frozen instances via a defensive prototype-shadowing fallback.
+- **Registry Security**: Refactored global registries (FORMAT, NUMBER, TIMEZONE) to use `registryUpdate` with core protection, preventing accidental overrides of built-in tokens.
+- **Anchor-Aware Parsing**: Added native support for anchoring relative date strings (e.g., "next Friday") to a specific reference date via the `anchor` option.
+- **Timezone Safety**: Implemented graceful fallback to `UTC` (with a warning) for invalid IANA TimeZone IDs when `catch: true` is enabled.
 
 ### Changed
-- **Config Architecture**: Relocated `pivot` property from `Tempo.Config` to `Tempo.Parse` to better align with its parsing-specific purpose.
-- **Type Accessibility**: Moved `TermPlugin` type definition to the public `Tempo` namespace for easier external plugin development.
-- **Initialization Logic**: Updated `Tempo.init()` to handle term registration and pivot defaults internally.
+- **Internal State Management**: Migrated from a static `#pending` accumulator to an instance-local `#matches` buffer, guaranteeing thread-safety for concurrent `Tempo` instances.
+- **Temporal Integration**: Unified the `Temporal` polyfill location to `#library/temporal.polyfill.js`.
+- **Typing Refactor**: Relocated `Internal` and `Tempo` namespaces to the top of `tempo.class.ts` for improved IDE type visibility and lint performance.
 
 ### Fixed
-- Resolved circular dependency between `tempo.class.ts` and `term.import.ts`.
-- Standardized internal property access for `pivot` using the `this.#local.parse["pivot"]` syntax.
-

-- Initial public release refinements.
-- Established documentation for vision and core features.
+- Resolved 299/299 regressions in the core and plugin test suites.
+- Fixed `TypeError: [object Object] is not extensible` during lazy discovery on secured instances.
+- Fixed relative calculation drift where "one Wednesday ago" used the system clock instead of the provided anchor.

+# @magmacomputing/magma-cli
+
+`magma-cli` is a lightweight, internal command-line tool built to unify build scripts across the Magma Computing monorepo.
+
+## Why does this exist?
+
+Many npm scripts traditionally rely on OS-specific shell commands (like `rm -rf`). This creates a fragile build environment that can break across different operating systems (such as Windows). Instead of pulling in external dependencies like `rimraf` or `del-cli`, `magma-cli` provides native, zero-dependency, cross-platform implementations specifically tailored for our build pipeline.
+
+## Usage
+
+This package registers the `magma-cli` binary. Because it is part of the npm workspace, npm automatically links it to the root `node_modules/.bin/magma-cli`. 
+
+You can use it directly in any `package.json` script within the monorepo:
+
+```json
+"scripts": {
+  "postbuild": "magma-cli rm dist/src"
+}
+```
+
+Or you can run it manually via `npx` from anywhere in the project:
+
+```bash
+npx magma-cli rm dist/src
+```
+
+## Available Commands
+
+### `rm <path...>`
+Recursively and forcefully removes the specified files or directories using Node's built-in `fs.rmSync`.
+- **Example:** `magma-cli rm dist/src build/ temp/`

+To extend `magma-cli` with new capabilities (e.g., cross-platform file copying), simply edit `index.js`. The CLI uses a lightweight argument router:
+
+```javascript
+const [command, ...args] = process.argv.slice(2);
+
+if (command === 'rm') {
+	// ...
+} else if (command === 'cp') {
+	// Add your new command implementation here
+} else {
+	console.error(`Unknown command: ${command}`);
+	process.exit(1);
+}
+```

+# Changelog
+
+All notable changes to the `@magmacomputing/tempo-plugin-astro` project will be documented in this file.
+
+## [2.1.2] - 2026-07-15
+
+### Fixed
+- Fixed an issue where the polynomial algorithm could return mathematical garbage for years outside the Jean Meeus limit. It now strictly enforces the `-1000` to `+3000` year bounds by throwing a `RangeError`.
+
+## [2.1.0] - 2026-07-02
+
+### Changed
+- **Open Source Transition**: The Astro plugin is now officially a Community plugin! It is 100% free and open-source under the MIT License.
+- **Licensing Removal**: Removed all proprietary licensing logic (`definePremiumTerm`) and initialization token checks.
+- **Clear-Text Build**: Removed `javascript-obfuscator` from the build pipeline. The published NPM artifact is now fully readable clear-text JavaScript.
+- Updated documentation and README to reflect the new open-source structure.
+
+## [1.1.6] - 2026-06-11
+
+### Changed
+- Renamed the metadata payload property `type` to `event` (Equinox vs. Solstice) to better reflect astronomical terminology and reduce naming collisions.
+- Refactored internal `calculateAstroMoment` parameter from `season` to `quarter` to resolve semantic ambiguity between meteorological seasons and astronomical quarters.
+- Augmented the `@magmacomputing/tempo/core` module to natively type the `TempoTermRegistry` for `astro` and `astronomy`, providing full strict IntelliSense autocomplete for IDEs.
+
+### Fixed
+- **Type Definitions**: Added missing `start: Tempo` and `end: Tempo` boundaries to the `TempoTermRegistry` augmentation, ensuring accurate typings for the dynamic range boundaries injected by the core resolver.
+- **NPM Registry Metadata**: Explicitly added `README.md`, `CHANGELOG.md`, and `LICENSE` to the `files` array in `package.json` to ensure the npmjs.com registry correctly renders package documentation.
+
+## [1.1.3] - 2026-06-07
+
+### Security
+- Migrated licensing enforcement from `jose` to the native WebCrypto Tempo Core primitives.
+
+### Fixed
+- Replaced all usage of the global `Date` object with the `instant()` temporal engine in the core validator to ensure timeline consistency.
+- Corrected test environment resolution boundaries that caused unhandled asynchronous Promise verification leaks.
+
+## [1.1.2] - 2026-06-04
+
+### Fixed
+- Resolved the "Ghost-Trap" architectural conflict that prevented validation when used with Tempo v3.0.0.
+- Decoupled `definePremiumTerm` and cryptographic validation from the plugin bundle. Licensing engine state and references are now directly imported from the Tempo Core (`@magmacomputing/tempo/plugin`).
+- Removed the `@magmacomputing/tempo-plugin-core` bundled `devDependency` to prevent duplicate initialization.
+
+## [1.0.2] - 2026-05-25
+
+### Security
+- Migrated licensing enforcement to the newly decoupled `@magmacomputing/tempo-plugin-core` workspace.
+- The proprietary license verification and string-obfuscation logic is now baked directly into the plugin bundle during the build step, decentralizing the security model and eliminating reliance on the open-source engine for validation.
+- Updated `devDependencies` to automatically resolve the new internal `@core` monorepo symlink via `tsup`.
+
+## [1.0.0] - 2026-05-18
+
+### Added
+- Initial release of the Astronomical Seasons plugin.
+- Implements the Jean Meeus polynomial approximation algorithm for precise Equinox and Solstice moments.
+- Returns fully scoped astronomical objects containing:
+  - Precise start/end dates for each astronomical season
+  - The astronomical `key` (Vernal, Summer, Autumnal, Winter)
+  - The colloquial traditional `season` mapping (Spring, Summer, Autumn, Winter)
+  - The `event` (Equinox vs. Solstice)
+- Fully supports automatic label inversion for Northern vs. Southern hemisphere configurations (`sphere: 'south'`).
+- Implements the `v2.10.0` Tempo Core Licensing API via cryptographic JSON Web Signatures (JWS).
+- Auto-registers itself via side-effect upon import.

+</p>
+
+This is a Community plugin for the [Tempo](https://github.com/magmacomputing/magma) library that provides precise astronomical events (Equinoxes and Solstices) and maps them to traditional season names based on hemisphere.
+
+👉 **[View the full documentation on our GitHub Pages](https://magmacomputing.github.io/magma/9-plugins/astro.html)**
+
+## Installation
+
+```bash
+npm install @magmacomputing/tempo-plugin-astro
+```
+
+## Usage
+
+```typescript
+import { Tempo } from '@magmacomputing/tempo';
+import { AstroTerm } from '@magmacomputing/tempo-plugin-astro';
+
+// Pass the plugin to `Tempo.init` to register it into the runtime.
+Tempo.init({ 
+  plugins: [AstroTerm] 
+});
+
+const t = new Tempo('2026-03-20');
+
+// Get the Astronomical Event mapping
+console.log(t.term.astro);
+// Output: 'Vernal'
+```
+
+### Response Payload
+
+When resolving the term, the plugin intelligently returns the correct astronomical event and its corresponding traditional season based on your configured hemisphere (`sphere`):
+
+```javascript
+{
+  key: 'Vernal',     // Flips to 'Autumnal' if sphere is set to 'south'
+  season: 'Spring',  // Flips to 'Autumn' if sphere is set to 'south'
+  sphere: 'north',   // Flips to 'south' if sphere is set to 'south'
+  event: 'Equinox',
+  group: 'astronomy',
+  year: 2026,
+  month: 3,
+  // ...
+}
+```
+
+> **Did you know?**
+> `t.term.astronomy.season` returns the *Astronomical* season calculated by the precise timing of solstices and equinoxes. This will often differ from `t.term.season` in the core library, which uses standard Meteorological/Civil calendar boundaries (e.g., 1st of the month).
+
+## Documentation

+</p>
+
+This is a Community plugin for the [Tempo](https://github.com/magmacomputing/magma) library that calculates the exact astronomical season (Equinoxes and Solstices) for any date using the **Jean Meeus polynomial algorithm**. 
+
+> [!NOTE]
+> **Mean-Polynomial Approximation (Ch. 27)**
+> This plugin specifically implements the mean-polynomial calculation from Chapter 27 of Meeus' *Astronomical Algorithms*. To keep the library extremely lightweight, it omits the massive periodic correction tables required for exact apparent calculations. It is strictly enforced to support the mathematical range of **-1000 to +3000 AD**.
+
+Because it is a true astronomical calculation rather than a fixed calendar date, it precisely determines the exact minute the sun crosses the celestial equator. It is also **hemisphere-aware**: by configuring your Tempo instance with a `sphere` (e.g., `sphere: 'south'`), the plugin accurately flips the Vernal Equinox from Spring to Autumn.
+
+::: info Meteorological vs Astronomical
+Unlike Tempo's built-in **Meteorological** `season` Term — which rigidly snaps to the 1st day of calendar months — this **Astronomical** plugin calculates the dynamic, true solar boundaries that shift slightly year-over-year.
+:::
+## Installation
+
+```bash
+npm install @magmacomputing/tempo-plugin-astro
+```
+
+## Usage
+
+```typescript
+import { Tempo } from '@magmacomputing/tempo';
+import { AstroTerm } from '@magmacomputing/tempo-plugin-astro';
+
+// Pass the plugin to `Tempo.init` to register it into the runtime.
+Tempo.init({ 
+  plugins: [AstroTerm] 
+});
+
+const t = new Tempo('2026-03-20');
+
+// Get the Astronomical Event mapping
+console.log(t.term.astro);
+// Output: 'Vernal'
+```
+
+### Response Payload
+
+When resolving the term, the plugin intelligently returns the correct astronomical event and its corresponding traditional season based on your configured hemisphere (`sphere`):
+
+```javascript
+{
+  key: 'Vernal',     // Flips to 'Autumnal' if sphere is set to 'south'
+  season: 'Spring',  // Flips to 'Autumn' if sphere is set to 'south'
+  sphere: 'north',   // Flips to 'south' if sphere is set to 'south'
+  event: 'Equinox',
+  group: 'astronomy',
+  year: 2026,
+  month: 3,
+  day: 20,
+  hour: 14,
+  minute: 45,
+  second: 0
+}
+```
+
+You can also access the full metadata object containing the sub-second precision fields via the `astronomy` term:
+
+```typescript
+console.log(t.term.astronomy);
+// Output: { key: 'Vernal', group: 'astronomy', year: 2026, month: 3, day: 20, hour: 14, minute: 45, ... }
+```
+
+::: tip Did you know?
+**Seasons:** `t.term.astronomy.season` returns the *Astronomical* season calculated by the precise timing of solstices and equinoxes. This will often differ from `t.term.season.key` in the core library, which uses standard Meteorological/Civil calendar boundaries (e.g., 1st of the month).

+# Changelog
+
+All notable changes to the `@magmacomputing/tempo-plugin-batch` project will be documented in this file.
+
+## [1.0.0] - 2026-06-29
+
+### Added
+- Initial release of the `tempo-plugin-batch` community plugin.
+- Implements `BatchOrchestrator` for extreme-throughput parallel processing of Tempo mutation tasks.
+- Utilizes a graceful degradation architecture: attempts lock-free `SharedArrayBuffer` mapping, gracefully falling back to `postMessage` arrays on unsupported environments.
+- Adds the `Tempo.batch(epochs, mutationArgs)` namespace for executing mutations across millions of timestamps simultaneously without blocking the main event loop.

+</p>
+
+This is a Community plugin for the [Tempo](https://github.com/magmacomputing/magma) library that parallelizes massive epoch mutation tasks across worker threads utilizing lock-free `SharedArrayBuffer` architecture for extreme throughput.
+
+👉 **[View the full documentation on our GitHub Pages](https://magmacomputing.github.io/magma/9-plugins/batch.html)**
+
+> **Perfect for:** Heavy data ETL pipelines, massive IoT telemetry ingestion, financial ledger chronometrics, and any parallel bulk date-processing workloads.
+
+## Installation
+
+```bash
+npm install @magmacomputing/tempo-plugin-batch
+```
+
+## Usage
+
+```typescript
+import { Tempo } from '@magmacomputing/tempo';
+import { BatchPlugin } from '@magmacomputing/tempo-plugin-batch';
+
+Tempo.init({ 
+  plugins: [BatchPlugin] 
+});
+
+// Assume `epochs` is a massive array of integers representing timestamps
+const epochs = [1700000000000, 1700000001000, /* ... millions more ... */];
+
+// Mutate millions of dates concurrently using the worker pool
+// The engine automatically splits the payload and offloads to workers!
+const batchResult = await Tempo.batch(epochs, { weeks: 1 });
+
+console.log(batchResult); // Returns an array of mutated timestamp integers
+```
+
+### Rehydration
+
+By default, `Tempo.batch` returns an array of primitive `number` timestamps to maximize throughput over the thread boundary. If you need fully-fledged `Tempo` objects back, pass `{ rehydrate: true }`:
+
+```typescript
+// Returns an array of Tempo instances instead of integers
+const tempoInstances = await Tempo.batch(epochs, { weeks: 1 }, { rehydrate: true });
+```
+
+### Graceful Degradation
+
+If the host environment does not support `SharedArrayBuffer` (or if it is blocked by CORS/COOP headers in the browser), the orchestrator intelligently and transparently falls back to using traditional `postMessage` structural cloning chunks to ensure execution never halts.
+
+## Licensing
+
+This is a **Community** plugin. It is completely free and open-source for personal and commercial use. No license token is required.
+
+For commercial licensing options, please contact Magma Computing.

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [1.3.1] - 2026-07-15
+
+### Fixed
+- **Sub-Second Precision Math**: The fractional rounding algorithm now accurately factors in all lower-level active components (e.g., nanoseconds now properly drift into milliseconds) for perfect precision.
+- **Safety Enforcer**: Added strict checks against `NaN` and `Infinity` inputs via `Number.isFinite()` to prevent infinite loops and math corruption.
+
+## [1.3.0] - 2026-07-08
+
+### Added
+- **Directional Snapping**: Added an optional `direction` parameter (`'up'` or `'down'`) to forcefully snap times using `Math.ceil` or `Math.floor` instead of standard round-to-nearest behavior.
+
+### Fixed
+- **Plugin API Import**: Updated `definePlugin` import to correctly point to the unified `@magmacomputing/tempo/plugin-api` barrel export.
+
+## [1.2.0] - 2026-07-08
+
+### Added
+- **Sub-Second Snapping**: Added support for snapping to sub-second precision (`ms`, `us`, `ns`) to support telemetry aggregation, multimedia synchronization, and database timestamp normalization.
+
+### Fixed
+
+- **Version Tracking**: Plugins will now register their 'version' with Tempo.versions
+
+## [1.1.0] - 2026-07-07
+
+### Changed
+
+- **Idiomatic Argument Syntax**: Refactored the `snap` method signature from positional arguments (`t.snap('mi', 15)`) to a standard object-based API (`t.snap({ mi: 15 })`) to natively align with Tempo's core mutation syntax.
+- **Shorthand Aliases**: Expanded the parameter typing to officially support long-form time aliases (e.g., `hours`, `minutes`, `seconds`) in addition to the standard shorthand keys (`hh`, `mi`, `ss`).
+
+### Fixed
+
+- **Runtime Validation**: Implemented strict runtime validation (powered by an internal `OneKey` utility type) to guarantee that only a single time component can be snapped at once. Passing date components (like `days` or `years`) will now safely throw explicit validation errors instead of silently failing.

+// Pass the plugin to `Tempo.init` to register it into the runtime.
+Tempo.init({ 
+  plugins: [SnapPlugin] 
+});
+
+const t = new Tempo('2026-06-01T14:08:00Z');
+
+// Snaps to the nearest 15 minutes by default
+const snapped = t.snap();
+console.log(snapped.format('{hh}:{mi}')); // "14:15"
+
+// Or explicitly provide units and intervals
+const snapHour = t.snap('hh', 1);
+const snapSecond = t.snap('ss', 30);
+```

+
+A Community plugin for the [Tempo](https://github.com/magmacomputing/magma) library that provides robust time rounding and snapping functionality (e.g., snapping to the nearest 15 minutes or 1 hour block) for calendar and scheduling applications.
+
+By default, the plugin effortlessly snaps dates to a configurable minute-interval. This is particularly useful when building UI components like time-pickers, ensuring data boundaries align perfectly with application logic.
+
+### 💡 User Notes: Why Sub-Second Snapping?
+While `hours` and `minutes` cover most UI use cases, sub-second precision (`ms`, `us`, `ns`) is invaluable for:
+1. **Telemetry & Log Aggregation**: Snapping high-frequency jittery timestamps to the nearest `100ms` or `500ms` bucket for cleaner charts and analysis.
+2. **Video & Audio Synchronization**: Multimedia frame rates require precise timing. Snap to the nearest `16ms` (approx 60fps) or `40ms` (25fps) to align data points with visual boundaries.
+3. **Database & API Normalization**: Truncating or snapping Tempo's native nanosecond precision to the nearest `ms` before sending payloads ensures your local application state perfectly matches remote databases that don't support microseconds.
+4. **Performance Benchmarking**: Grouping execution times into buckets (e.g., nearest `10ms`) for histograms.
+
+## Installation
+
+```bash
+npm install @magmacomputing/tempo-plugin-snap
+```
+
+## Usage
+
+```typescript
+import { Tempo } from '@magmacomputing/tempo';
+import { SnapPlugin } from '@magmacomputing/tempo-plugin-snap';
+
+// Pass the plugin to `Tempo.init` to register it into the runtime.
+Tempo.init({ 
+  plugins: [SnapPlugin] 
+});
+
+const t = new Tempo('2026-06-01T14:08:00Z');
+
+// Snaps to the nearest 15 minutes by default
+const snapped = t.snap();
+console.log(snapped.format('{hh}:{mi}')); // "14:15"
+
+// Or explicitly provide units and intervals
+const snapHour = t.snap({ hh: 1 });
+const snapSecond = t.snap({ ss: 30 });
+const snapMs = t.snap({ ms: 100 });
+
+// Force snapping direction instead of standard rounding
+const snapUp = t.snap({ mi: 15, direction: 'up' });
+const snapDown = t.snap({ mi: 15, direction: 'down' });
+```

+# Changelog
+
+All notable changes to the `@magmacomputing/tempo-plugin-sync` project will be documented in this file.
+
+## [1.0.0] - 2026-06-29
+
+### Added
+
+- Initial release of the `tempo-plugin-sync` (AtomicClock) premium plugin.
+- Implements `AtomicClock` (Master) and `AtomicReader` (Worker) components for `O(1)` non-blocking time synchronization.
+- Utilizes `SharedArrayBuffer` and native `Atomics` for nanosecond-accurate multi-threading.
+- Exposes `now()` (millisecond fallback) and `nowNano()` (BigInt nanoseconds) on the `AtomicReader`.
+- Directly supports hydrating `Tempo` engine instances with zero precision-loss.

+// Master Thread: Start the clock
+const clock = Tempo.sync.startClock({ updateIntervalMs: 1 });
+const buffer = clock.buffer; // Pass this SharedArrayBuffer to your workers
+```
+
+### Reading from Worker Threads
+
+To read the synchronized time from inside a worker thread, pass the `SharedArrayBuffer` via `workerData` and instantiate an `AtomicReader`.
+
+```typescript
+// worker.ts
+import { workerData } from 'node:worker_threads';
+import { AtomicReader } from '@magmacomputing/tempo-plugin-sync';
+
+// Hydrate the reader using the master buffer
+const reader = new AtomicReader(workerData.buffer);
+
+// 1. Get raw milliseconds (O(1) Atomic Read)
+const ms = reader.now(); 
+
+// 2. Get high-precision BigInt nanoseconds
+const ns = reader.nowNano();
+
+// 3. Hydrate a brand new Tempo instance with exact precision
+const t = reader.getTempo();
+```

+</p>
+
+This is a premium plugin for the [Tempo](https://github.com/magmacomputing/magma) library that provides a high-performance continuous execution loop (Ticker) based on temporal mathematics.
+
+::: info High Performance Loop
+Unlike standard `setInterval` or `requestAnimationFrame`, the Ticker plugin leverages Tempo's robust temporal core to ensure exact sub-millisecond precision, making it ideal for games, complex UI animations, and accurate state synchronization.
+:::
+
+## Installation
+
+```bash
+npm install @magmacomputing/tempo-plugin-ticker
+```
+
+## Usage
+
+To use the Ticker, pass the plugin to `Tempo.init` to ensure it registers securely alongside your license.
+
+```typescript
+import { Tempo } from '@magmacomputing/tempo';
+import { TickerPlugin } from '@magmacomputing/tempo-plugin-ticker';
+
+// A valid premium license token is required to use this plugin
+Tempo.init({ 
+  license: 'YOUR_LICENSE_TOKEN',
+  plugins: [TickerPlugin] 
+});
+
+// You can now access Ticker-based execution loops through the Tempo API:
+const ticker = Tempo.ticker({ seconds: 1 });
+```
+
+### Direct Access
+If you need to access the [Reporting & Registry](#reporting-registry) API (like `Ticker.active`), you should import the `Ticker` namespace:
+
+```typescript
+import { Ticker } from '@magmacomputing/tempo-plugin-ticker';
+
+console.log(Ticker.active);
+```
+
+## 🚀 Key Features
+
+The Ticker supports a unified **Options** object, enabling professional resource management and semantic duration-based intervals.
+
+### 1. Semantic Intervals (Duration Objects)
+Instead of raw numeric seconds, you can use `DurationLike` objects or shorthand keys for clarity. This is especially powerful for variable-length intervals like **months**.
+
+```typescript
+// Pulse exactly once a month
+await using monthly = Tempo.ticker({ months: 1 });
+
+// You can also use highly compact shorthand keys
+await using concise = Tempo.ticker({ hh: 1, mi: 30 }); // every 1h 30m
+
+// Pulse every time a new #quarter begins
+await using quarterly = Tempo.ticker({ '#quarter': 1 });
+```
+
+### 2. Term-Based Intervals
+Ticker intervals can now be driven by any registered **Term**. This is powerful for syncing with business cycles or daily shifts.
+
+```typescript
+// Pulse at the start of every 'morning', 'afternoon', etc.
+using shiftTicker = Tempo.ticker({ '#period': 1 }, (t) => {
+  console.log(`New period started: ${t.term.per}`);
+});
+```
+
+### 3. Stop Conditions (Resource Management)
+Prevent memory leaks and runaway processes by setting a built-in termination condition.
+
+```typescript
+// Pattern A: Stop after exactly 5 ticks (defaults to 1-second interval)
+using tickerA = Tempo.ticker({ limit: 5 }, (t) => console.log(t));
+
+// Pattern B: Stop when a specific virtual time is reached (Inclusive)
+using tickerB = Tempo.ticker({ 
+  seconds: 10,               // Plural DurationLike property
+  until: '2024-12-25T12:00:00' 
+}, (t) => console.log(t));
+
+// Pattern C: Stop immediately (Limit: 0 is strictly honored)
+using tickerC = Tempo.ticker({ limit: 0 }); 
+```
+
+### 4. Virtual Clock (Seeding)
+To create a **Virtual Clock** that increments from a specific point rather than using the system time, use the `seed` option:
+
+```typescript
+// Starts at '2024-01-01', then increments by 1 day per pulse
+await using daily = Tempo.ticker({ 
+  days: 1, 
+  seed: '2024-01-01' 
+});
+```
+
+### 5. Backwards Tickers (Countdowns)
+By providing a **negative** interval, you can create a Ticker that moves backwards in time. 
+
+```typescript
+// Count down from 10 seconds, moving backwards 1s at a time
+using countdown = Tempo.ticker({ seconds: -1, seed: "00:00:10" }, (t, stop) => {
+  console.log(t.format('{ss}'));
+  if (t.ss === 0) stop(); 
+});
+```
+
+## Usage Patterns
+
+### 1. Resource Management (Recommended)
+
+Using the `using` and `await using` keywords ensures that Tickers are automatically stopped when they go out of scope.
+
+```typescript
+// Pattern A: Automatic cleanup for callback-based ticker
+{
+  using ticker = Tempo.ticker((t) => render(t)); // Defaults to a 1-second pulse
+} // interval stops automatically here
+
+// Pattern B: Automatic cleanup for async generator
+{
+  await using ticker = Tempo.ticker(1);
+  for await (const t of ticker) {
+    if (done) break;
+  }
+} // generator is closed and interval stops here
+```
+
+### 2. Manual Control (Programmatic Stop)
+
+If you are not using the `using` or `await using` keywords, or if you need to stop the Ticker from outside its own loop (e.g., in a separate event handler), you can manually call the `stop()` method on the Ticker object.
+
+```typescript
+// Pattern A: Stop a callback-based ticker
+const tickerA = Tempo.ticker(1, (t) => console.log(t));
+// ... later
+tickerA.stop();
+
+// Pattern B: Stop an async generator externally
+const tickerB = Tempo.ticker(1);
+
+(async () => {
+  for await (const t of tickerB) {
+    console.log(t.toString());
+  }
+  console.log('Ticker has been gracefully stopped.');
+})();
+
+// Close the generator from somewhere else
+setTimeout(() => {
+  tickerB.stop();
+}, 5000);
+```
+### 3. Event Listeners (.on)
+Instead of (or in addition to) the constructor callback, you can register listeners for the `'pulse'`, `'stop'`, and `'catch'` events.
+All listeners use the same callback signature: `(t, stop) => {}`.
+
+```typescript
+const ticker = Tempo.ticker(1);
+ticker.on('pulse', (t) => console.log('Listener A:', t.fmt.weekTime));
+ticker.on('pulse', (t) => console.log('Listener B:', t.fmt.weekTime));
+ticker.on('stop', (t) => console.log('Ticker stopped at:', t.fmt.weekTime));
+```
+For `'stop'` listeners, the `stop` callback argument is included for signature consistency; however, invoking it after stop has already occurred is a no-op.
+
+### 4. Manual Pulsing (.pulse)
+In some scenarios, you may want to drive a Ticker manually (e.g., from a UI event or a WebSocket message) while still benefiting from the Ticker's internal state management and listeners.
+
+```typescript
+const ticker = Tempo.ticker({ seconds: 1 }); // Still has a 1s duration logic
+// ...
+ticker.pulse(); // Manually advance and notify listeners
+```
+
+## 🧟 Zombie Tickers (Warning) {#zombie-tickers-warning}
+
+In a Node.js environment, `Tempo.ticker()` uses background timers (`setTimeout`) to drive its pulses. If you do not explicitly stop a Ticker, it becomes a **"Zombie Ticker"** that continues to run indefinitely, even if the variable that created it has gone out of scope.
+
+### The Risks:
+- **Process Hangs**: Node.js will not exit a process if there are active timers. Undisposed Tickers are a common cause of "mysterious hangs" at the end of test runs.
+- **Test Inconsistency**: Leaked Tickers can continue to fire while subsequent tests are running, leading to flaky assertions and "impossible" state changes.
+- **Memory Leaks**: Each active Ticker maintains closures that prevent garbage collection of the `Tempo` instance and its listeners.
+
+### The Solution:
+Always use the **Disposer Pattern** (`using` or `await using`) or a `try...finally` block to guarantee cleanup:
+
+```typescript
+// ✅✅ BEST: Automatic cleanup via 'using'
+{
+  using ticker = Tempo.ticker(1);
+  // ... logic ...
+} // Stays clean: ticker stopped automatically here
+
+// ✅ GOOD: Manual cleanup in finally block (Required for captured variables)
+let ticker;
+try {
+  ticker = Tempo.ticker(1, (t) => { ... });
+  // ... assertions ...
+} finally {
+  ticker?.stop(); // Prevents "Zombie Tickers" even if assertions fail
+}
+```
+
+::: warning
+If you are using `const` or `let` without a `finally` block, an assertion failure will skip the `stop()` call, leaving a live timer in the event loop. Always prefer the `using` keyword or `try...finally` for industrial-grade resource management.
+:::
+
+### `Ticker` Object
+The object returned by `Tempo.ticker()` (or an instance of the `Ticker` class) implements the following interface:
+
+| Method / Property | Description |
+| :--- | :--- |
+| `on(event, cb)` | Registers a listener for the `'pulse'`, `'stop'`, or `'catch'` events. |
+| `pulse()` | Manually triggers a pulse, advances state, and notifies listeners. Returns the new `Tempo`. |
+| `info` | Read-only getter returning `{ next, ticks, limit, interval, stopped }`. |
+| `stop()` | Stops the Ticker, clears active timers, and immediately resolves any pending async iteration Promises. |
+| `[Symbol.dispose]` | Standard cleanup for `using` blocks. |
+| `[Symbol.asyncDispose]` | Standard async cleanup for `await using` blocks. |
+| `[Symbol.asyncIterator]` | Standard async iteration support (for `for await` loops). |
+
+## Reporting & Registry {#reporting-registry}
+
+The `Ticker` class maintains a static registry of all currently active Tickers. This is useful for debugging, monitoring, or cleanup checks.
+
+### `Ticker.active`
+A static getter that returns an array of [`Ticker.Snapshot`](#tickersnapshot) objects for all active (non-stopped) Tickers.
+
+```typescript
+import { Ticker } from '@magmacomputing/tempo-plugin-ticker';
+
+// Get a report of all running tickers
+const reports = Ticker.active;
+
+reports.forEach(({ ticker, next, ticks }) => {
+  console.log(`Ticker ${ticker} next pulse: ${next}, ticks so far: ${ticks}`);
+});
+```
+
+#### `Ticker.Snapshot`
+```typescript
+type Snapshot = {
+  ticker: Instance;     // The Ticker instance (Proxy) itself
+  next: Tempo;          // The next Tempo value to be emitted
+  ticks: number;        // Number of pulses emitted so far
+  limit?: number;       // The configured limit (if any)
+  interval: object;     // The duration-based interval
+  stopped: boolean;     // Whether the ticker is stopped
+}
+```
+
+## 🎯 One-Shot Ticker (Meeting Alerts)
+
+You can use the Ticker as a "one-shot" timer for specific events by simply specifying a **seed** value. This is perfect for setting up a single alert (e.g., for a meeting) that cleans itself up immediately after firing.
+
+::: tip
+**Seed-Only Logic**: Providing a `seed` (as a string or in an options object) without any other duration-based keys (`seconds`, `minutes`, etc.) or a `limit` implies a `limit: 1`. 
+
+Effectively, `Tempo.ticker('Fri 10am')` and `Tempo.ticker({ seed: 'Fri 10am' })` and `Tempo.ticker({ seed: 'Fri 10am', limit: 1 })` are all treated as one-shot Tickers.
+
+**Inclusive Boundaries**: Termination conditions (`limit` and `until`) are **inclusive**. A Ticker with `limit: 1` will pulse exactly once before stopping.
+:::
+
+```typescript
+// Pattern A: Implicit one-shot via string seed
+Tempo.ticker('Friday 10am', (t) => {
+  console.log(`Meeting alert: ${t.format('{hh}:{mi}')}`);
+});
+
+// Pattern B: Explicit one-shot via options
+const event = { meeting: 'Friday 10am' };
+
+Tempo.ticker({ 
+  seed: { value: 'meeting', event }
+}, (t) => {
+  console.log(`Meeting alert: ${t.format('{hh}:{mi}')}`);
+});
+```
+
+::: warning
+**Future Seeds**: If the `seed` is in the future, the Ticker will remain dormant (waiting) until that time is reached. **Most Tickers emit an initial pulse immediately** (at the `seed` time or "now"), but a future seed will delay that first pulse until the specified time.
+:::
+
+::: danger
+**Persistence**: Ticker timers exist only **in-memory**. If the driving process (e.g., Node.js) terminates, any scheduled future pulses (including those from future seeds) are lost. For critical long-term scheduling, consider an external persistent job runner.
+:::
+
+::: warning
+While `limit: 1` handles the stop condition automatically, always remember that if you are using long-running Tickers without a limit, you **must** use the [Disposer Pattern](#zombie-tickers-warning) or manual `stop()` to avoid memory leaks and zombie processes.
+:::
+
+## 🧭 Advanced: Syncing Multiple Clocks
+
+If you need to show multiple timezones on a dashboard, avoid creating multiple Tickers. Instead, use a single **Master Ticker** to drive all views. This prevents "drift" between the clocks and is much more efficient.
+
+### Using Signals (Recommended)
+
+Signals (from Preact, Solid, or Vue) are perfect for this "one source, many views" pattern.
+
+```typescript
+// 1. Master source of truth
+const now = signal(new Tempo());
+
+// 2. Drive the master from a single ticker
+using _ = Tempo.ticker(1, (t) => now.value = t);
+
+// 3. Derived timezones update automatically and stay 100% in sync
+const sydney = computed(() => now.value.set({ timeZone: 'Australia/Sydney' }));
+const london = computed(() => now.value.set({ timeZone: 'Europe/London' }));
+```
+
+### Using Async Generators (Framework-Agnostic)
+
+If you are not using a reactive framework, you can use the same pattern with an `AsyncGenerator` to derive all clocks from a single pulse.
+
+```typescript
+// One generator, one interval, zero drift.
+await using master = Tempo.ticker(1);
+
+for await (const t of master) {
+  const clocks = {
+    sydney: t.set({ timeZone: 'Australia/Sydney' }),
+    ny:     t.set({ timeZone: 'America/New_York' }),
+    london: t.set({ timeZone: 'Europe/London' })
+  };
+  
+  renderDashboard(clocks);
+}
+```
+
+## Licensing
+
+This is a **Premium** plugin. Usage requires an active, cryptographically signed Tempo license token with the `ticker` scope enabled.

+## [3.9.0] - 2026-07-14
+
+### Added
+- **Era Parsing Engine**: Upgraded the `ParseModule` and Lexer to natively support parsing historical and future era dates with explicit markers (e.g. `200 BC`, `BC 200`, `2026 CE`). Supports both leading and trailing formats and flawlessly converts to the astronomical ISO 8601 year.
+- **Era Formatting & Getters**: Added native support for the `{era}` and `{eraYear}` formatting tokens. Introduced `.era` and `.eraYear` getters on the core `Tempo` class for zero-cost access to historical date components.
+- **Auto-Meridiem Spacing**: Implemented the `:space` modifier for the `{h12}` formatting token (e.g., `{h12:space:dots}`). This enables typographically correct spacing before automatically injected meridiems (e.g., `"10:30 a.m."`).
+
+### Changed
+- **Documentation Alignment**: Cleaned up `tempo.config.md` to remove deprecated module references, perfectly aligning examples with the `tempo-workspace` ecosystem (`FinancePlugin` and `AstroTerm`).
+- **Getter Documentation**: Created `tempo.getters.md` as the definitive, educational conceptual guide for utilizing Tempo's zero-cost evaluation getters.
+
+### Fixed
+- **Core Typings**: Resolved `any` leakage in `Tempo` core methods by injecting strict overloads for `until()` and `since()` directly into `tempo.class.ts`, ensuring full IDE type-inference flows through to `.format()`.
+- **Documentation Badges**: Standardized the Shields.io badge layout across the monorepo to use `<p>` tags with `inline-block` styling, fixing horizontal alignment issues caused by VitePress CSS overrides and eliminating malformed HTML `<table>` hydration errors.
+- **Vue Compiler Hydration**: Fixed a rogue unclosed `</p>` tag in the Ticker plugin documentation that was silently causing downstream Vue SFC parsing errors during VitePress compilation.
+- **CLI Pipeline**: Validated the `magma-cli` build pipeline to correctly propagate non-zero exit codes during workspace orchestration operations, preventing silent failures.

-# Tempo API Reference
-
-This document provides a comprehensive technical reference for the `Tempo` class, including static methods, properties, and instance API.
-
----
-
-- [TypeScript Types Reference](./tempo.types.md)
-- [Tempo Cookbook](../doc/tempo.cookbook.md)
-
----
-
-## 🏗️ Constructor
-
-You can instantiate `Tempo` in several ways:
-
-- **`new Tempo()`**: Defaults to current time ("now").
-- **`new Tempo(dateTime)`**: Parses a date-time value.
-- **`new Tempo(dateTime, options)`**: Parses with specific configuration.
-- **`new Tempo(options)`**: Defaults to "now" with specific configuration.
-
-### Valid `dateTime` Types:
-- **`string`**: ISO 8601, natural language ("tomorrow", "next Friday"), or custom patterns.
-- **`number`**: Unix timestamps in milliseconds (default) or microseconds.
-- **`BigInt`**: Unix timestamps in nanoseconds.
-- **`Date`**: Standard JavaScript `Date` object.
-- **`Tempo`**: Clones another Tempo instance.
-- **`Temporal.*`**: Any native Temporal object (ZonedDateTime, PlainDate, etc.).
-
----
-
-## 🏗️ Static Methods
-
-### `Tempo.init(options?: Tempo.Options)`
-Initializes the global default configuration for all subsequent `Tempo` instances.
-- **Returns:** `Tempo.Config` (The resolved global config).
-- **Note:** Settings are inherited from library defaults, persistent storage, and provided options. Use `silent: true` to suppress `console.error` output for expected failures.
-
-### `Tempo.extend(arg, options?)`
-Unified extender for library functionality.
-- **Plugin:** `Tempo.extend(TickerPlugin)` — Adds functional extensions.
-- **Term:** `Tempo.extend(MyTerm)` — Registers grammar/parsing terms.
-- **Discovery:** `Tempo.extend(config)` — Bootstraps global configuration.
-  **Formats:** `Tempo.extend(MyFormat)` — Registers custom format strings.
-
-- **Returns:** `typeof Tempo` (for chaining).
-- **Note:** Plugins are installed only once; existing core members are protected.
-
-### `Tempo.from(tempo?: Tempo.DateTime | Tempo.Options, options?: Tempo.Options)`
-Creates a new `Tempo` instance. A static alternative to `new Tempo()`.
-- **Returns:** `Tempo`
-
-### `Tempo.compare(tempo1, tempo2?)`
-Compares two `Tempo` instances or date-time values for sorting.
-- **Returns:** `-1` (smaller), `0` (equal), or `1` (larger).
-
-### `Tempo.duration(input)`
-(Plugin required) Creates a full Tempo Duration object (EDO) from an ISO string or DurationLike object.
-- **Returns:** `Tempo.Duration`
-- **Example:** `Tempo.duration('P1Y')` or `Tempo.duration({ months: 2 })`
-
-### `Tempo.now()`
-Returns the current Unix epoch in nanoseconds as a `BigInt`.
-
-### `Tempo.getSymbol(key?: string | symbol)`
-Retrieves or registers a `Symbol` for internal token mapping.
-
-### `Tempo.ticker(arg1?, arg2?)`
-(Plugin required) Creates a reactive stream of `Tempo` instances at regular intervals. 
-- **Returns:** An `AsyncGenerator` (if no callback) or a `stop` function (if callback provided).
-- **See:** [Tempo Ticker Guide](../doc/tempo.ticker.md) for the full polymorphic signature and usage patterns.
-
-### `Tempo.regexp(layout, snippet?)`
-Translates a Tempo layout string into a compiled `RegExp`.
-
-### `Tempo[Symbol.dispose]()`
-Releases the global configuration and resets the library to its initial defaults. Equivalent to calling `Tempo.init()`.
-
----
-
-## ⚙️ Static Properties
-
-### `Tempo.config`
-Returns the current *global* configuration settings.
-
-### `Tempo.default`
-Returns the *initial* out-of-the-box library defaults.
-
-### `Tempo.terms`
-Returns an array of all currently registered term plugins.
-
-### `Tempo.parse`
-Returns the global parsing rules registry (snippets, layouts, events, etc.).
-
-### `Tempo.properties`
-Returns a list of all public static accessor names on the `Tempo` class.
-
-### 🔢 Static Enumerators
-Access to the internal dictionaries used by Tempo:
-- `WEEKDAY` | `WEEKDAYS`
-- `MONTH` | `MONTHS`
-- `SEASON` | `COMPASS`
-- `DURATION` | `DURATIONS`
-- `ELEMENT` (Units map)
-- `FORMAT` (Registry of pre-defined formats)
-- `LIMIT` (Useful boundary dates)
-
----
-
-## 🚀 Instance Methods
-
-### `tempo.add(payload: Tempo.DateTime | Tempo.Add, options?: Tempo.Options)`
-Returns a **new** `Tempo` instance with the specified duration or date-time payload added.
-- **Example:** `t.add({ days: 2 })` or `t.add('tomorrow')`
-
-### `tempo.set(payload: Tempo.DateTime | Tempo.Set, options?: Tempo.Options)`
-Returns a **new** `Tempo` instance with specific values or relative alignments.
-- **Example:** `t.set({ month: 5, hh: 12 })` or `t.set({ start: 'month' })` landing on `01-May 00:00:00`.
-- **Note (End):** Using `end` with an anchor (e.g., `set({ end: '#qtr' })`) lands on the **Inclusive End** of the period (e.g., `30-Sep 23:59:59.999...`). This follows industry UX expectations for "end-of-period" navigation.
-- **Note (Mid):** Using `mid` with an anchor lands on the **Arithmetic Mid-point** (exact nanosecond center) of the period.
-
-### `tempo.clone()`
-Returns a **new**, lean `Tempo` instance based on the current one. It preserves all local configuration but starts a fresh "parse history" (length 1). This is ideal for minimizing memory footprint in long chains or live tickers.
-
-### `tempo.format(fmt: string)`
-Returns a formatted string or number based on the provided token or named format.
-
-### `tempo.until(until, opts?)`
-Calculates the duration until another date-time.
-- **Returns:** `number` (if a unit is provided) or a `Tempo.Duration` object.
-
-### `tempo.since(since?: Tempo.DateTime | Tempo.Options, opts?: Tempo.Options)`
-Returns a human-readable relative time string (e.g., "3 days ago").
-- **Returns:** `string`
-- **Options:** 
-  - `rtfStyle`: `'long' | 'short' | 'narrow'` (default: `'narrow'`). See `Intl.RelativeTimeFormatStyle`.
-  - `rtfFormat`: A pre-configured `Intl.RelativeTimeFormat` instance.
-- **Example:** 
-  - `t.since('yesterday')` -> `"1d ago"`
-  - `t.since('yesterday', { rtfStyle: 'long' })` -> `"1 day ago"`
-  - `t.since(t2, { rtfFormat: new Intl.RelativeTimeFormat('fr') })` -> `"il y a 2 heures"`
-- **Performance:** Tempo memoizes `Intl` object creation internally. For maximum performance in high-volume loops, you can pass a pre-allocated `rtfFormat` instance.
-
-### `tempo.isValid`
-Returns `true` if the instance represents a valid date-time.
-
-### `tempo.toString()`
-Returns the ISO 8601 string representation.
-
-### `tempo.toDate()`
-Returns a standard JavaScript `Date` object.
-
-### `tempo.toDateTime()`
-Returns the underlying `Temporal.ZonedDateTime` object.
-
-### `tempo.toInstant()`
-Returns the underlying `Temporal.Instant` object.
-
-### `tempo.toPlainDate()`
-Returns a `Temporal.PlainDate` representation.
-
-### `tempo.toPlainTime()`
-Returns a `Temporal.PlainTime` representation.
-
-### `tempo.toPlainDateTime()`
-Returns a `Temporal.PlainDateTime` representation.
-

-# TypeScript Types Reference
-
-This document provides a reference for the core TypeScript types and interfaces used within the `Tempo` namespace. These types define the valid inputs, configuration options, and manipulation arguments for the library.
-
-## `Tempo.DateTime`
-The primary type used for arguments representing a point in time. `Tempo` is extremely flexible and can interpret a wide range of formats. It also provides methods to extract these back as `Temporal` objects (e.g., `toPlainDate()`, `toInstant()`, etc.).
-
-```typescript
-type DateTime = 
-  | string                      // ISO strings, relative strings ('next Friday'), etc.
-  | number                      // Unix timestamp in milliseconds
-  | bigint                      // Unix timestamp in nanoseconds
-  | Date                        // Standard JavaScript Date object
-  | Tempo                       // Another Tempo instance (cloning)
-  | Function                    // Dynamic resolution (max depth 5)
-  | Temporal.ZonedDateTimeLike  // Temporal ZonedDateTime object or property bag
-  | undefined | null            // Interpreted as "now"
-```
-
-## `Tempo.Options`
-Configuration options that can be passed to `Tempo.init()` or the `Tempo` constructor.
-
-```typescript
-interface Options {
-  timeZone?: string;            // IANA zone (e.g., 'UTC', 'America/New_York') or alias
-  locale?: string;              // BCP 47 language tag (e.g., 'en-US', 'en-AU')
-  calendar?: string;            // Calendar system (default: 'iso8601')
-  pivot?: number;               // Cutoff for 2-digit years (default: 75)
-  debug?: boolean;              // Enable internal log tracking
-  catch?: boolean;              // If true, invalid inputs return a Void instance
-  store?: string;               // Key for persistent storage (e.g., localStorage)
-  sphere?: 'north' | 'south';   // Hemisphere for seasonal plugins
-  relativeTime?: { format?: Intl.RelativeTimeFormat, style?: 'long' | 'short' | 'narrow' };
-  monthDay?: boolean | { active?: boolean, locales?: string[], layouts?: [string, string][], timezones?: Record<string, string[]> };
-  timeStamp?: 'ms' | 'ns';      // Precision for numeric timestamps
-  [key: string]: any;           // Allows custom configurations shared with plugins
-}
-```
-
-## `Tempo.Add`
-Used by the `.add()` method to specify a duration to add or subtract.
-
-```typescript
-type Add = Partial<Record<Tempo.Unit, number>>;
-
-// Example:
-t.add({ days: 5, hours: -2 });
-```
-
-## `Tempo.Set`
-Used by the `.set()` method to move to a specific unit boundary or date-time alias.
-
-```typescript
-type Set = Partial<
-  Record<'start' | 'mid' | 'end', Tempo.Unit> &
-  Record<'date' | 'time' | 'event' | 'period', string>
->;
-
-// Examples:
-t.set({ start: 'month' });    // Start of the month
-t.set({ event: 'xmas' });     // Relative or absolute event alias
-t.set({ time: '14:30' });     // Specific time string
-```
-
-## `Tempo.Unit`
-Valid date and time unit strings used throughout the API.
-
-```typescript
-type Unit = 
-  | 'year' | 'month' | 'week' | 'day' 
-  | 'hour' | 'minute' | 'second' 
-  | 'millisecond' | 'microsecond' | 'nanosecond'
-  | 'years' | 'months' | 'weeks' | 'days' // Plurals are also supported
-  // ... etc.
-```
-
-## `Tempo.Until`
-The argument passed to `.until()` and `.since()`.
-
-```typescript
-type Until = 
-  | (Tempo.Options & { unit?: Tempo.Unit }) 
-  | Tempo.Unit;
-
-// Examples:
-t.until('2025-01-01', 'days');
-t.since('yesterday', { timeZone: 'UTC' });
-```
-
-## `Tempo.Discovery`
-The contract for global discovery via `Symbol.for($Tempo)`.
-
-```typescript
-interface Discovery {
-  options?: Options | (() => Options);
-  timeZones?: Record<string, string>;
-  terms?: TermPlugin | TermPlugin[];
-  plugin?: Plugin | Plugin[];
-  numbers?: Record<string, number>;
-  formats?: Record<string, string>;
-}
-```
-
-## `Tempo.TermPlugin`
-The interface for defining custom business-logic plugins.
-
-```typescript
-type TermPlugin = {
-  key: string;                  // Short name on t.term (e.g., 'qtr')
-  scope?: string;               // Full name for range object (e.g., 'quarter')
-  description: string;          // Human-readable description
-  define: (this: Tempo, keyOnly?: boolean) => any;
-}
-```
-
-## `Tempo.TickerOptions`
-Advanced configuration for `Tempo.ticker()`. Extends `Temporal.DurationLike` (plural keys only).
-
-```typescript
-type TickerOptions = Partial<Temporal.DurationLike> & {
-  interval?: number | string | bigint;    // Scalar interval (seconds if number)
-  limit?: number;                         // Total number of ticks to emit
-  until?: Tempo.DateTime;                 // Virtual deadline (inclusive)
-  seed?: Tempo.DateTime | Tempo.Options;  // Starting point for virtual clock
-}
-```

+# 🧲 Core Getters
+
+The `Tempo` class provides an extensive array of zero-cost getters that allow you to seamlessly read properties from the underlying `Temporal` instance. 
+
+> [!TIP]
+> **Zero-Cost Lazy Evaluation**  
+> Tempo uses a sophisticated proxy-based lazy-evaluation pattern. Accessing a getter (like `t.yy`) resolves the property on demand, and then overwrites the getter with a static literal. This means the first access is `O(1)` and every subsequent access is raw property access (`O(0)` cost).
+
+## 📅 Date Properties
+
+| Getter | Type | Description | Example |
+| :--- | :--- | :--- | :--- |
+| `.yy` | `number` | 4-digit Year | `2026` |
+| `.mm` | `number` | Month number (1 = Jan, 12 = Dec) | `10` |

+### Historical Era Parsing
+Tempo natively supports parsing historical and future dates with era designations such as `BC`, `BCE`, `AD`, and `CE`. 
+It correctly resolves both trailing (`200 BC`) and leading (`BC 200`) formats.
+
+> [!WARNING]
+> **Era Parsing Assumptions**
+> When parsing dates with eras, be aware of the following architectural rules:
+> 1. **Implicit Defaults**: If no era is explicitly provided in the string, Tempo safely assumes `CE` (Common Era).
+> 2. **Missing Months/Days**: If a historical era string like `"200 BC"` is parsed without a month or day, Tempo anchors the missing components to **January 1st** of that astronomical year (i.e., `-199-01-01`).
+> 3. **Calendar Systems**: Era parsing and conversion to astronomical years is strictly restricted to the **ISO/Gregorian** calendar system. This mathematically means `1 BC` becomes astronomical year `0`, and `200 BC` becomes year `-199`.

 # 📜 Version 3.x History
 
+## [v3.9.0] - 2026-07-14
+
+### ✨ What's New
+
+**Historical Era Support**
+Introduced first-class support for historical dates. The new `{era}` formatting token automatically resolves to localized BC/AD or BCE/CE designations. Additionally, the core `Tempo` class now exposes `.era` and `.eon` zero-cost getters, providing immediate access to the underlying historical date components.
+
+**Typographical Auto-Meridiem**
+Expanded the `{h12}` token modifiers with a new `:space` option. When chaining modifiers (like `{h12:space:dots}`), Tempo will now gracefully inject a readability space before the auto-appended meridiem, yielding typographically correct strings like `"10:30 a.m."` instead of `"10:30a.m."`.
+
+### 📚 Documentation Enhancements
+- **Educational Guides**: Created a brand new `tempo.getters.md` document in the Core Concepts section, serving as the definitive guide to Tempo's zero-cost lazy-evaluation properties.
+- **Ecosystem Alignment**: Updated `tempo.config.md` to remove deprecated plugin references, replacing them with accurate examples from the current `tempo-workspace` (`FinancePlugin` and `AstroTerm`).
+
+### 🪲 Bug Fixes & Stability
+- **Core Typings**: Resolved `any` leakage in `Tempo` core methods by injecting strict overloads for `until()` and `since()` directly into `tempo.class.ts`, ensuring full IDE type-inference flows through to `.format()`.
+- **Documentation Badges**: Standardized the Shields.io badge layout across the monorepo to use `<p>` tags with `inline-block` styling, fixing horizontal alignment issues caused by VitePress CSS overrides and eliminating malformed HTML `<table>` hydration errors.
+- **Vue Compiler Hydration**: Fixed a rogue unclosed `</p>` tag in the Ticker plugin documentation that was silently causing downstream Vue SFC parsing errors during VitePress compilation.
+- **CLI Pipeline**: Validated the `magma-cli` build pipeline to correctly propagate non-zero exit codes during workspace orchestration operations, preventing silent failures.

+</p>
+
+This is a Community plugin for the [Tempo](https://github.com/magmacomputing/magma) library that calculates the exact astronomical season (Equinoxes and Solstices) for any date using the **Jean Meeus polynomial algorithm**. 
+
+> [!NOTE]
+> **Mean-Polynomial Approximation (Ch. 27)**
+> This plugin specifically implements the mean-polynomial calculation from Chapter 27 of Meeus' *Astronomical Algorithms*. To keep the library extremely lightweight, it omits the massive periodic correction tables required for exact apparent calculations. It is strictly enforced to support the mathematical range of **-1000 to +3000 AD**.
+
+Because it is a true astronomical calculation rather than a fixed calendar date, it precisely determines the exact minute the sun crosses the celestial equator. It is also **hemisphere-aware**: by configuring your Tempo instance with a `sphere` (e.g., `sphere: 'south'`), the plugin accurately flips the Vernal Equinox from Spring to Autumn.
+
+::: info Meteorological vs Astronomical
+Unlike Tempo's built-in **Meteorological** `season` Term — which rigidly snaps to the 1st day of calendar months — this **Astronomical** plugin calculates the dynamic, true solar boundaries that shift slightly year-over-year.
+:::
+## Installation
+
+```bash
+npm install @magmacomputing/tempo-plugin-astro
+```
+
+## Usage
+
+```typescript
+import { Tempo } from '@magmacomputing/tempo';
+import { AstroTerm } from '@magmacomputing/tempo-plugin-astro';
+
+// Pass the plugin to `Tempo.init` to register it into the runtime.
+Tempo.init({ 
+  plugins: [AstroTerm] 
+});
+
+const t = new Tempo('2026-03-20');
+
+// Get the Astronomical Event mapping
+console.log(t.term.astro);
+// Output: 'Vernal'
+```
+
+### Response Payload
+
+When resolving the term, the plugin intelligently returns the correct astronomical event and its corresponding traditional season based on your configured hemisphere (`sphere`):
+
+```javascript
+{
+  key: 'Vernal',     // Flips to 'Autumnal' if sphere is set to 'south'
+  season: 'Spring',  // Flips to 'Autumn' if sphere is set to 'south'
+  sphere: 'north',   // Flips to 'south' if sphere is set to 'south'
+  event: 'Equinox',
+  group: 'astronomy',
+  year: 2026,
+  month: 3,
+  day: 20,
+  hour: 14,
+  minute: 45,
+  second: 0
+}
+```
+
+You can also access the full metadata object containing the sub-second precision fields via the `astronomy` term:
+
+```typescript
+console.log(t.term.astronomy);
+// Output: { key: 'Vernal', group: 'astronomy', year: 2026, month: 3, day: 20, hour: 14, minute: 45, ... }
+```
+
+::: tip Did you know?
+**Seasons:** `t.term.astronomy.season` returns the *Astronomical* season calculated by the precise timing of solstices and equinoxes. This will often differ from `t.term.season.key` in the core library, which uses standard Meteorological/Civil calendar boundaries (e.g., 1st of the month).

+This is a Community plugin for the [Tempo](https://github.com/magmacomputing/magma) library that parallelizes massive epoch mutation tasks across worker threads utilizing lock-free `SharedArrayBuffer` architecture for extreme throughput.
+
+::: tip Perfect For
+Heavy data ETL pipelines, massive IoT telemetry ingestion, financial ledger chronometrics, and any parallel bulk date-processing workloads.
+:::
+
+## Installation
+
+```bash
+npm install @magmacomputing/tempo-plugin-batch
+```
+
+## Usage
+
+```typescript
+import { Tempo } from '@magmacomputing/tempo';
+import { BatchPlugin } from '@magmacomputing/tempo-plugin-batch';
+
+Tempo.init({ 
+  plugins: [BatchPlugin] 
+});
+
+// Assume `epochs` is a massive array of integers representing timestamps
+const epochs = [1700000000000, 1700000001000, /* ... millions more ... */];
+
+// Mutate millions of dates concurrently using the worker pool
+// The engine automatically splits the payload and offloads to workers!
+const batchResult = await Tempo.batch(epochs, { weeks: 1 });
+
+console.log(batchResult); // Returns an array of mutated timestamp integers
+```
+
+### Rehydration
+
+By default, `Tempo.batch` returns an array of primitive `number` timestamps to maximize throughput over the thread boundary. If you need fully-fledged `Tempo` objects back, pass `{ rehydrate: true }`:
+
+```typescript
+// Returns an array of Tempo instances instead of integers
+const tempoInstances = await Tempo.batch(epochs, { weeks: 1 }, { rehydrate: true });
+```
+
+### Graceful Degradation
+
+If the host environment does not support `SharedArrayBuffer` (or if it is blocked by CORS/COOP headers in the browser), the orchestrator intelligently and transparently falls back to using traditional `postMessage` structural cloning chunks to ensure execution never halts.

+
+A Community plugin for the [Tempo](https://github.com/magmacomputing/magma) library that provides robust time rounding and snapping functionality (e.g., snapping to the nearest 15 minutes or 1 hour block) for calendar and scheduling applications.
+
+By default, the plugin effortlessly snaps dates to a configurable minute-interval. This is particularly useful when building UI components like time-pickers, ensuring data boundaries align perfectly with application logic.
+
+### 💡 User Notes: Why Sub-Second Snapping?
+While `hours` and `minutes` cover most UI use cases, sub-second precision (`ms`, `us`, `ns`) is invaluable for:
+1. **Telemetry & Log Aggregation**: Snapping high-frequency jittery timestamps to the nearest `100ms` or `500ms` bucket for cleaner charts and analysis.
+2. **Video & Audio Synchronization**: Multimedia frame rates require precise timing. Snap to the nearest `16ms` (approx 60fps) or `40ms` (25fps) to align data points with visual boundaries.
+3. **Database & API Normalization**: Truncating or snapping Tempo's native nanosecond precision to the nearest `ms` before sending payloads ensures your local application state perfectly matches remote databases that don't support microseconds.
+4. **Performance Benchmarking**: Grouping execution times into buckets (e.g., nearest `10ms`) for histograms.
+
+## Installation
+
+```bash
+npm install @magmacomputing/tempo-plugin-snap
+```
+
+## Usage
+
+```typescript
+import { Tempo } from '@magmacomputing/tempo';
+import { SnapPlugin } from '@magmacomputing/tempo-plugin-snap';
+
+// Pass the plugin to `Tempo.init` to register it into the runtime.
+Tempo.init({ 
+  plugins: [SnapPlugin] 
+});
+
+const t = new Tempo('2026-06-01T14:08:00Z');
+
+// Snaps to the nearest 15 minutes by default
+const snapped = t.snap();
+console.log(snapped.format('{hh}:{mi}')); // "14:15"
+
+// Or explicitly provide units and intervals
+const snapHour = t.snap({ hh: 1 });
+const snapSecond = t.snap({ ss: 30 });
+const snapMs = t.snap({ ms: 100 });
+
+// Force snapping direction instead of standard rounding
+const snapUp = t.snap({ mi: 15, direction: 'up' });
+const snapDown = t.snap({ mi: 15, direction: 'down' });

+const buffer = clock.buffer; // Pass this SharedArrayBuffer to your workers
+```
+
+### Reading from Worker Threads
+
+To read the synchronized time from inside a worker thread, pass the `SharedArrayBuffer` via `workerData` and instantiate an `AtomicReader`.
+
+```typescript
+// worker.ts
+import { workerData } from 'node:worker_threads';
+import { AtomicReader } from '@magmacomputing/tempo-plugin-sync';
+
+// Hydrate the reader using the master buffer
+const reader = new AtomicReader(workerData.buffer);
+
+// 1. Get raw milliseconds (O(1) Atomic Read)
+const ms = reader.now(); 
+
+// 2. Get high-precision BigInt nanoseconds
+const ns = reader.nowNano();
+
+// 3. Hydrate a brand new Tempo instance with exact precision
+const t = reader.getTempo();
+```

+</p>
+
+This is a premium plugin for the [Tempo](https://github.com/magmacomputing/magma) library that provides a high-performance continuous execution loop (Ticker) based on temporal mathematics.
+
+::: info High Performance Loop
+Unlike standard `setInterval` or `requestAnimationFrame`, the Ticker plugin leverages Tempo's robust temporal core to ensure exact sub-millisecond precision, making it ideal for games, complex UI animations, and accurate state synchronization.
+:::
+
+## Installation
+
+```bash
+npm install @magmacomputing/tempo-plugin-ticker
+```
+
+## Usage
+
+To use the Ticker, pass the plugin to `Tempo.init` to ensure it registers securely alongside your license.
+
+```typescript
+import { Tempo } from '@magmacomputing/tempo';
+import { TickerPlugin } from '@magmacomputing/tempo-plugin-ticker';
+
+// A valid premium license token is required to use this plugin
+Tempo.init({ 
+  license: 'YOUR_LICENSE_TOKEN',
+  plugins: [TickerPlugin] 
+});
+
+// You can now access Ticker-based execution loops through the Tempo API:
+const ticker = Tempo.ticker({ seconds: 1 });
+```
+
+### Direct Access
+If you need to access the [Reporting & Registry](#reporting-registry) API (like `Ticker.active`), you should import the `Ticker` namespace:
+
+```typescript
+import { Ticker } from '@magmacomputing/tempo-plugin-ticker';
+
+console.log(Ticker.active);
+```
+
+## 🚀 Key Features
+
+The Ticker supports a unified **Options** object, enabling professional resource management and semantic duration-based intervals.
+
+### 1. Semantic Intervals (Duration Objects)
+Instead of raw numeric seconds, you can use `DurationLike` objects or shorthand keys for clarity. This is especially powerful for variable-length intervals like **months**.
+
+```typescript
+// Pulse exactly once a month
+await using monthly = Tempo.ticker({ months: 1 });
+
+// You can also use highly compact shorthand keys
+await using concise = Tempo.ticker({ hh: 1, mi: 30 }); // every 1h 30m
+
+// Pulse every time a new #quarter begins
+await using quarterly = Tempo.ticker({ '#quarter': 1 });
+```
+
+### 2. Term-Based Intervals
+Ticker intervals can now be driven by any registered **Term**. This is powerful for syncing with business cycles or daily shifts.
+
+```typescript
+// Pulse at the start of every 'morning', 'afternoon', etc.
+using shiftTicker = Tempo.ticker({ '#period': 1 }, (t) => {
+  console.log(`New period started: ${t.term.per}`);
+});
+```
+
+### 3. Stop Conditions (Resource Management)
+Prevent memory leaks and runaway processes by setting a built-in termination condition.
+
+```typescript
+// Pattern A: Stop after exactly 5 ticks (defaults to 1-second interval)
+using tickerA = Tempo.ticker({ limit: 5 }, (t) => console.log(t));
+
+// Pattern B: Stop when a specific virtual time is reached (Inclusive)
+using tickerB = Tempo.ticker({ 
+  seconds: 10,               // Plural DurationLike property
+  until: '2024-12-25T12:00:00' 
+}, (t) => console.log(t));
+
+// Pattern C: Stop immediately (Limit: 0 is strictly honored)
+using tickerC = Tempo.ticker({ limit: 0 }); 
+```
+
+### 4. Virtual Clock (Seeding)
+To create a **Virtual Clock** that increments from a specific point rather than using the system time, use the `seed` option:
+
+```typescript
+// Starts at '2024-01-01', then increments by 1 day per pulse
+await using daily = Tempo.ticker({ 
+  days: 1, 
+  seed: '2024-01-01' 
+});
+```
+
+### 5. Backwards Tickers (Countdowns)
+By providing a **negative** interval, you can create a Ticker that moves backwards in time. 
+
+```typescript
+// Count down from 10 seconds, moving backwards 1s at a time
+using countdown = Tempo.ticker({ seconds: -1, seed: "00:00:10" }, (t, stop) => {
+  console.log(t.format('{ss}'));
+  if (t.ss === 0) stop(); 
+});
+```
+
+## Usage Patterns
+
+### 1. Resource Management (Recommended)
+
+Using the `using` and `await using` keywords ensures that Tickers are automatically stopped when they go out of scope.
+
+```typescript
+// Pattern A: Automatic cleanup for callback-based ticker
+{
+  using ticker = Tempo.ticker((t) => render(t)); // Defaults to a 1-second pulse
+} // interval stops automatically here
+
+// Pattern B: Automatic cleanup for async generator
+{
+  await using ticker = Tempo.ticker(1);
+  for await (const t of ticker) {
+    if (done) break;
+  }
+} // generator is closed and interval stops here
+```
+
+### 2. Manual Control (Programmatic Stop)
+
+If you are not using the `using` or `await using` keywords, or if you need to stop the Ticker from outside its own loop (e.g., in a separate event handler), you can manually call the `stop()` method on the Ticker object.
+
+```typescript
+// Pattern A: Stop a callback-based ticker
+const tickerA = Tempo.ticker(1, (t) => console.log(t));
+// ... later
+tickerA.stop();
+
+// Pattern B: Stop an async generator externally
+const tickerB = Tempo.ticker(1);
+
+(async () => {
+  for await (const t of tickerB) {
+    console.log(t.toString());
+  }
+  console.log('Ticker has been gracefully stopped.');
+})();
+
+// Close the generator from somewhere else
+setTimeout(() => {
+  tickerB.stop();
+}, 5000);
+```
+### 3. Event Listeners (.on)
+Instead of (or in addition to) the constructor callback, you can register listeners for the `'pulse'`, `'stop'`, and `'catch'` events.
+All listeners use the same callback signature: `(t, stop) => {}`.
+
+```typescript
+const ticker = Tempo.ticker(1);
+ticker.on('pulse', (t) => console.log('Listener A:', t.fmt.weekTime));
+ticker.on('pulse', (t) => console.log('Listener B:', t.fmt.weekTime));
+ticker.on('stop', (t) => console.log('Ticker stopped at:', t.fmt.weekTime));
+```
+For `'stop'` listeners, the `stop` callback argument is included for signature consistency; however, invoking it after stop has already occurred is a no-op.
+
+### 4. Manual Pulsing (.pulse)
+In some scenarios, you may want to drive a Ticker manually (e.g., from a UI event or a WebSocket message) while still benefiting from the Ticker's internal state management and listeners.
+
+```typescript
+const ticker = Tempo.ticker({ seconds: 1 }); // Still has a 1s duration logic
+// ...
+ticker.pulse(); // Manually advance and notify listeners
+```
+
+## 🧟 Zombie Tickers (Warning) {#zombie-tickers-warning}
+
+In a Node.js environment, `Tempo.ticker()` uses background timers (`setTimeout`) to drive its pulses. If you do not explicitly stop a Ticker, it becomes a **"Zombie Ticker"** that continues to run indefinitely, even if the variable that created it has gone out of scope.
+
+### The Risks:
+- **Process Hangs**: Node.js will not exit a process if there are active timers. Undisposed Tickers are a common cause of "mysterious hangs" at the end of test runs.
+- **Test Inconsistency**: Leaked Tickers can continue to fire while subsequent tests are running, leading to flaky assertions and "impossible" state changes.
+- **Memory Leaks**: Each active Ticker maintains closures that prevent garbage collection of the `Tempo` instance and its listeners.
+
+### The Solution:
+Always use the **Disposer Pattern** (`using` or `await using`) or a `try...finally` block to guarantee cleanup:
+
+```typescript
+// ✅✅ BEST: Automatic cleanup via 'using'
+{
+  using ticker = Tempo.ticker(1);
+  // ... logic ...
+} // Stays clean: ticker stopped automatically here
+
+// ✅ GOOD: Manual cleanup in finally block (Required for captured variables)
+let ticker;
+try {
+  ticker = Tempo.ticker(1, (t) => { ... });
+  // ... assertions ...
+} finally {
+  ticker?.stop(); // Prevents "Zombie Tickers" even if assertions fail
+}
+```
+
+::: warning
+If you are using `const` or `let` without a `finally` block, an assertion failure will skip the `stop()` call, leaving a live timer in the event loop. Always prefer the `using` keyword or `try...finally` for industrial-grade resource management.
+:::
+
+### `Ticker` Object
+The object returned by `Tempo.ticker()` (or an instance of the `Ticker` class) implements the following interface:
+
+| Method / Property | Description |
+| :--- | :--- |
+| `on(event, cb)` | Registers a listener for the `'pulse'`, `'stop'`, or `'catch'` events. |
+| `pulse()` | Manually triggers a pulse, advances state, and notifies listeners. Returns the new `Tempo`. |
+| `info` | Read-only getter returning `{ next, ticks, limit, interval, stopped }`. |
+| `stop()` | Stops the Ticker, clears active timers, and immediately resolves any pending async iteration Promises. |
+| `[Symbol.dispose]` | Standard cleanup for `using` blocks. |
+| `[Symbol.asyncDispose]` | Standard async cleanup for `await using` blocks. |
+| `[Symbol.asyncIterator]` | Standard async iteration support (for `for await` loops). |
+
+## Reporting & Registry {#reporting-registry}
+
+The `Ticker` class maintains a static registry of all currently active Tickers. This is useful for debugging, monitoring, or cleanup checks.
+
+### `Ticker.active`
+A static getter that returns an array of [`Ticker.Snapshot`](#tickersnapshot) objects for all active (non-stopped) Tickers.
+
+```typescript
+import { Ticker } from '@magmacomputing/tempo-plugin-ticker';
+
+// Get a report of all running tickers
+const reports = Ticker.active;
+
+reports.forEach(({ ticker, next, ticks }) => {
+  console.log(`Ticker ${ticker} next pulse: ${next}, ticks so far: ${ticks}`);
+});
+```
+
+#### `Ticker.Snapshot`
+```typescript
+type Snapshot = {
+  ticker: Instance;     // The Ticker instance (Proxy) itself
+  next: Tempo;          // The next Tempo value to be emitted
+  ticks: number;        // Number of pulses emitted so far
+  limit?: number;       // The configured limit (if any)
+  interval: object;     // The duration-based interval
+  stopped: boolean;     // Whether the ticker is stopped
+}
+```
+
+## 🎯 One-Shot Ticker (Meeting Alerts)
+
+You can use the Ticker as a "one-shot" timer for specific events by simply specifying a **seed** value. This is perfect for setting up a single alert (e.g., for a meeting) that cleans itself up immediately after firing.
+
+::: tip
+**Seed-Only Logic**: Providing a `seed` (as a string or in an options object) without any other duration-based keys (`seconds`, `minutes`, etc.) or a `limit` implies a `limit: 1`. 
+
+Effectively, `Tempo.ticker('Fri 10am')` and `Tempo.ticker({ seed: 'Fri 10am' })` and `Tempo.ticker({ seed: 'Fri 10am', limit: 1 })` are all treated as one-shot Tickers.
+
+**Inclusive Boundaries**: Termination conditions (`limit` and `until`) are **inclusive**. A Ticker with `limit: 1` will pulse exactly once before stopping.
+:::
+
+```typescript
+// Pattern A: Implicit one-shot via string seed
+Tempo.ticker('Friday 10am', (t) => {
+  console.log(`Meeting alert: ${t.format('{hh}:{mi}')}`);
+});
+
+// Pattern B: Explicit one-shot via options
+const event = { meeting: 'Friday 10am' };
+
+Tempo.ticker({ 
+  seed: { value: 'meeting', event }
+}, (t) => {
+  console.log(`Meeting alert: ${t.format('{hh}:{mi}')}`);
+});
+```
+
+::: warning
+**Future Seeds**: If the `seed` is in the future, the Ticker will remain dormant (waiting) until that time is reached. **Most Tickers emit an initial pulse immediately** (at the `seed` time or "now"), but a future seed will delay that first pulse until the specified time.
+:::
+
+::: danger
+**Persistence**: Ticker timers exist only **in-memory**. If the driving process (e.g., Node.js) terminates, any scheduled future pulses (including those from future seeds) are lost. For critical long-term scheduling, consider an external persistent job runner.
+:::
+
+::: warning
+While `limit: 1` handles the stop condition automatically, always remember that if you are using long-running Tickers without a limit, you **must** use the [Disposer Pattern](#zombie-tickers-warning) or manual `stop()` to avoid memory leaks and zombie processes.
+:::
+
+## 🧭 Advanced: Syncing Multiple Clocks
+
+If you need to show multiple timezones on a dashboard, avoid creating multiple Tickers. Instead, use a single **Master Ticker** to drive all views. This prevents "drift" between the clocks and is much more efficient.
+
+### Using Signals (Recommended)
+
+Signals (from Preact, Solid, or Vue) are perfect for this "one source, many views" pattern.
+
+```typescript
+// 1. Master source of truth
+const now = signal(new Tempo());
+
+// 2. Drive the master from a single ticker
+using _ = Tempo.ticker(1, (t) => now.value = t);
+
+// 3. Derived timezones update automatically and stay 100% in sync
+const sydney = computed(() => now.value.set({ timeZone: 'Australia/Sydney' }));
+const london = computed(() => now.value.set({ timeZone: 'Europe/London' }));
+```
+
+### Using Async Generators (Framework-Agnostic)
+
+If you are not using a reactive framework, you can use the same pattern with an `AsyncGenerator` to derive all clocks from a single pulse.
+
+```typescript
+// One generator, one interval, zero drift.
+await using master = Tempo.ticker(1);
+
+for await (const t of master) {
+  const clocks = {
+    sydney: t.set({ timeZone: 'Australia/Sydney' }),
+    ny:     t.set({ timeZone: 'America/New_York' }),
+    london: t.set({ timeZone: 'Europe/London' })
+  };
+  
+  renderDashboard(clocks);
+}
+```
+
+## Licensing
