WS-002 closes the review findings: sealed-handoff transition matrix, append-only audit events (unused delete APIs removed), dedicated v2 fixture, and an interrupted v3-to-v4 migration test proving transactional rollback and recovery. WS-003 adds a capability-reporting ProviderSessionAdapter with Codex and Claude implementations that preserve current CLI start/resume behavior, reject cross-provider fork, report unsupported operations honestly, sequence events monotonically, and stop idempotently. WS-004's minimum slice adds ReviewAuthorityService and a deterministic, lease-serialized, idempotent ProjectBridge with machine-local content screening, plus a boundary-aware recording path now wired into the AppModel preflight flow, and a full fake-adapter Claude-to-Codex-and-back round-trip test. swift test --disable-sandbox: 164 executed, 1 intentional live-provider skip, 0 failures.

A continuity project grants no filesystem authority; + workspace approval remains a separate explicit boundary. +2. **Opaque local identity.** Continuity rows reference only local UUIDs + (`conversationID` or `externalSessionID`, exactly one per link, enforced in + the model, in DDL CHECK constraints, and by reference validation). Raw + provider session identifiers, provider paths, and transcript bodies never + enter serializable continuity models. +3. **Provider separation and handoff-not-fork.** Provider identity lives on + the linked session records, never coalesced across providers. + Cross-provider movement is expressed exclusively as `ContinuityHandoff` + between session links. Fork remains a same-provider operation of the + provider adapter layer (WS-003) and is rejected across providers there. +4. **Append-only audit.** `ContinuityEvent` is immutable (all stored + properties are constants; the store exposes insert and read only). Sync + history advances by revision; corrections supersede rather than rewrite. +5. **Sealed handoffs.** A handoff is editable in `draft` and `ready`. Once + `acknowledged` it is sealed: title, summary, destination, and creation time + are frozen and the only legal transition is to `superseded`. A `superseded` + handoff is terminal and fully frozen. Acknowledgment is only reachable from + `ready` (store-enforced transition matrix). +6. **Bounded canonical text.** Every continuity text field is NFC-normalized, + trimmed, control-character-free, and byte-bounded (name 512 B, title 512 B, + summary 16 KiB, event detail 4 KiB), mirrored by DDL CHECK constraints. + Continuity fields are deliberately single-line; multi-line portable context + belongs to the separately validated 32 KiB continuity capsule. +7. **One writer, read-only review.** Writer ownership is a store-level CAS + lease (`ContinuityWriterLease` for sync transactions, + `ContinuityWorkstreamWriterLease` per workstream) with bounded duration + (1–300 s), monotonic revisions, expiry, and a fail-closed reconciliation + marker that survives reopen and clears only with digest-validated audit + evidence. Reviewer permission produces no writer transaction + (lease-gate-enforced and view-model-enforced). + +## Review findings routed to WS-002 + +The independent audit accepted the model layer and identified two +store-enforcement gaps, both closed under WS-002 ownership: + +- `upsertContinuityHandoff` previously allowed rewriting an `acknowledged` or + `superseded` handoff and moving state backwards; a transition matrix now + enforces seal semantics. +- Unused `deleteContinuityEvent` and `deleteContinuityHandoff` APIs + contradicted the append-only decision and were removed. Project and + session-link deletion remain as explicit owner data-management operations + whose cascades are covered by foreign-key tests; narrowing them further is a + WS-012 acceptance question. + +## Consequences + +- Model invariants are characterized in + `Tests/CommandCenterCoreTests/ContinuityModelsTests.swift`; persistence, + migration, seal, and lease behavior in the WS-002 store suites. +- Handoff supersession requires creating a successor handoff rather than + editing history, which the UI must surface as lineage (WS-005). +- The capsule codec, preflight, and lease gate consume this contract + unchanged; WS-004 bridge work builds on immutable session-link tips plus the + workstream lease and must not introduce any bypass of the seal or lease + rules.

Adds a provider non-affiliation statement and marks PROJECT_HANDOFF.md and .claude/orchestration/ as intentionally local-only working artifacts so the public docs carry no dangling references.

Do not apply Anthropic's orange, +Poppins, and Lora brand system to this provider-neutral product. Avoid purple +AI gradients, brains, robots, sparkles, cyberpunk terminal green, literal yarn +balls, and decorative knots. + +## SEO and launch language + +Use the distinctive product name for navigation and the category terms in +descriptive copy. Initial keyword themes: + +- local coding-agent workspace; +- Claude Code and Codex session manager; +- coding-agent handoff; +- cross-agent context; +- local-first coding-agent history; +- verified agent continuity; and +- native macOS coding-agent workspace. + +Suggested homepage title: + +> Threadbraid — Local continuity for coding agents on macOS + +Suggested meta description: + +> Find, resume, and hand off Claude Code and Codex work from one native Mac +> workspace, with verified local context and explicit permissions. + +Do not force `Threadbraid` into copy repeatedly. Pair it with descriptive +category language until the name earns navigational search demand. + +## Brand review gates + +Before shipping public copy: + +1. Distinguish verified current behavior from roadmap behavior. +2. Substantiate privacy, performance, and compatibility claims with current + evidence. +3. Avoid `only`, `best`, `fastest`, `fully private`, or similar unsupported + superlatives. +4. Use provider names descriptively and include a non-affiliation statement. +5. Confirm trademark, domain, package, repository, and App Store identities. +6. Review the final mark for similarity to existing software and provider + identities. + +## Decision required + +Owner acceptance of **Threadbraid by Openly Useful** turns this recommendation +into a rename plan. Until then, Local Command Center remains the engineering +working title and all public-brand changes are proposals.
