Sibling answers called +some exclusion counts "files"; review corrected these to **entries**, which can +include directories.

Flash usage is unknown.

Thirty helper tests and a local +HTTP 402 fixture passed. No provider retry was made; the original discarded +body remains unavailable. This helper repair is outside the Context package. + +The three client sessions reported the following cumulative usage across their +requests, including the rejected Oathrun query and its recovery: + +| Project | Input tokens | Cached input (subset) | Output tokens | +| --- | ---: | ---: | ---: | +| Context | 188,812 | 166,912 | 959 | +| KithMoot | 188,474 | 165,888 | 1,063 | +| Oathrun | 169,272 | 147,712 | 849 | +| Total | 546,558 | 480,512 | 2,871 | + +These are CLI-reported usage counters, not invoices or single-prompt sizes. +Repeated client context contributes even when retrieved source is small. Cached +input is already included in input; reported reasoning tokens are already +included in output. There was no paired baseline for these acceptance tasks. + +Host and Codex-worker costs and review time are not fully attributed. This +delivery therefore establishes no cash saving. Private receipts retain failed +attempts and the diagnosis; raw prompts and machine paths are not published. + +## Second adoption pass + +A qualified `gpt-5.6-sol`/high review reproduced three navigation defects: +replacing a root directory left old project content searchable; changing ignore +policy during source inspection could return newly excluded text; and a source +ancestor swap could open a different file after discovery. The repaired engine +binds generations to canonical root/device/inode, rechecks policy after source +reads and before cursor commit, and compares opened source handles with their +discovered identity before reading. Nonblocking opens prevent a substituted +special file from blocking that identity check. These remain operator-owned +filesystem checks, not a sandbox or atomic snapshot. + +The independent root-replacement reproduction returned one old result on the +previous installed build and none on the repaired build, which blocked search +with unknown policy until explicit refresh. All 66 focused policy/navigation +tests and the 107-test tools suite passed during the repair. + +A fresh Luna/medium Codex client against the rebuilt checkout completed +unavailable → current → edit → stale → refresh → current and rejected the old +cursor. An earlier attempt reached the freshness states but had only one exact +posting and therefore no cursor; its usage and incomplete outcome were retained. +Both directions of the KithMoot/Oathrun negative retrieval check passed in fresh +Codex clients on the preceding installed build. Fresh SDK clients repeated the +positive-and-negative root checks on the repaired checkout. The disabled Codex +session reported no repository tools and invoked none; its configuration also +showed `enabled=false`. Codex JSONL does not expose a raw available-tool inventory, +so that specific acceptance remains open. + +The [worker packet helper](WORKER-PACKETS.md) is a checkout developer script. +It uses explicit roots, navigation selection policy, exact excerpts, whole-file +hashes, allowed-file states, policy provenance and Git HEAD. Packet construction +is deterministic and rejects excessive input/output instead of truncating it. +Root identity and relevant source/policy checks run again before publication. +Git HEAD is provenance and does not assert a clean working tree. + +Two ordinary coding tasks have accepted outcomes: a Terra/medium worker built +the packet helper from a manually assembled, hashed source packet, and a fresh +Terra/medium Codex session implemented verification from a 37,630-byte packet +produced by that helper. The second session used navigation, checked source +hashes before editing, passed its tests and refreshed afterwards. Review repairs +covered nested selection, root identity, policy-check ordering, snapshot checks, +duplicate ranges, bounded excerpt construction and temporary-fixture cleanup. +An initial verifier invocation failed local configuration parsing before a model +turn; the corrected invocation and subsequent review work are retained. + +The full repository check passed **154 tests** (33 core, 107 tools, 14 packet +helper), plus independent package/browser/CLI smoke. The nine-check navigation +smoke and both unchanged benchmark gates passed. A real helper CLI smoke built +and verified a private packet, then correctly rejected the older coding packet +after its source changed. Packet tests also cover edits outside the excerpt, +allowed-file changes, policy and HEAD changes, wrong roots, malformed input, +exclusive output and the retargeted-root regression. + +Actual routing in this pass used Terra/medium for packet implementation and +client orchestration, Sol/high for the consequential boundary review and repair, +Luna/medium for fresh acceptance clients, and local Qwen with thinking off for +the runbook draft. Qwen reported 469 input and 634 output tokens; its draft was +partially retained after host corrections. Flash was not retried. Host GPT-6 +handled integration and review; complete host/worker cost attribution is still +unavailable, and this pass establishes no whole-task monetary saving. + +The seven recorded Codex task sessions in this pass reported 966,308 cumulative +input tokens, including 853,504 cached input tokens, and 10,668 output tokens. +Those totals include the incomplete lifecycle attempt; cached input is a subset +and reasoning output is already included. Collaboration-worker and host usage +remain unavailable. These are acceptance and development receipts without a +paired baseline, not an inference-cost comparison. + +The repairs and helper are committed as `10c9d65` and `2dd3fc7` respectively. +[Candidate CI passed](https://github.com/forgesworn/context/actions/runs/35600896950) +for `2dd3fc7ab1f202e94b8fcba4b336773b675b9d1b`, including package checks, +benchmarks, navigation smoke and synthetic scale checks. Tarballs from that clean +commit were installed in a separate commit-pinned directory. The installed CLI +passed all nine smoke checks and positive/negative retrieval in both sibling +roots. A fresh Luna/medium Codex session then repeated the complete lifecycle, +including old-cursor rejection, against that exact installed release. + +All three local client bindings now select the new pinned release with their +original explicit roots. Existing sessions need restarting to load it; an index +refresh does not reload implementation code. The preceding pinned release and +private per-root configuration backups remain available for rollback. This is +internal installation and client acceptance, not registry publication or room +consumer acceptance. The packet helper itself remains a checkout script. + +## Worker availability recovery + +On 21 September 2026, after the pinned-build acceptance, the operator requested +DeepSeek and Ollama recovery for everyday work. Read-only checks found both +daemons on version 0.34.2 with no helper pending marker. Account metadata reported +`free` for this Mac's port 11434 and `max` for the M4 tunnel on port 11435. +The earlier Flash 402 was on port 11434; its discarded body remains unavailable, +so the plan difference is not proof of that refusal's cause. + +Two new, independent tasks through the M4 tunnel completed with HTTP 200: + +| Model | Thinking | Task and host review | Reported input / output | Seconds | +| --- | --- | --- | --- | --- | +| `qwen3.8:latest` | Off | Endpoint facts extracted as JSON; every supplied field and model name checked and accepted | 150 / 179 | 5.119 | +| `deepseek-v4.1-flash:cloud` | Off | Recovery checklist; partially retained with explicit loopback address, precise helper responsibilities and request-specific refusal wording | 230 / 179 | 2.236 | + +The first Qwen dispatch encountered an occupied helper lock before inference. +After checking that no pending marker or lock owner remained, a fresh output +directory was used. The busy receipt was retained; it has no reported usage. +Initial diagnostic CLI argument errors and GET requests to the POST-only account +metadata endpoint also made no inference requests. + +This verifies local Qwen and cloud Flash availability on the M4 for subsequent +authorised tasks. It does not qualify Pro or reconcile its two earlier Oathrun +jobs. No refused task was replayed, no reservation was cleared, and no account +limit or auto-top-up setting changed. The local-port refusal remains terminal. +The helper default already selects the M4; daily commands now make the endpoint +explicit to avoid environment-dependent selection. + +Private prompt, response and review receipts are retained under the +`20260921-worker-recovery-4vm3a4cz` evidence directory. Host GPT-6 reviewed the +outputs and edited these instructions; exact host effort and usage are not +available. Successful worker usage totals 380 input and 358 output tokens; +there is no paired baseline or monetary savings claim. + +## D5 report tooling; experiment remains open + +The developer-only [whole-task reporter](TASK-COST-REPORT.md) validates a declared +eight-pair protocol and private receipts. It preserves missing evidence as +incomplete, includes failed attempts, keeps cached/reasoning token subsets +separate, and requires attributed variable costs rather than estimating money +from worker usage. Cost and review decisions compare decimal amounts exactly; +floating-point rounding cannot relax either decision threshold. The committed +template is explicitly unlocked, with placeholder definitions and no results. + +This development task used Context navigation and bounded source packets. +`package.json` was excluded by the source extension policy; its exact content +was read separately and retained with its hash. No navigation scope was widened. +Sol/high designed and reviewed the measurement boundaries. Two Flash/thinking-off +implementation responses through the M4 reached their output limits and were +rejected without applying source. Terra/medium implemented the reporter and +repaired review findings. A later narrow Flash packet supplied three useful +regressions; one incorrect result-field assertion was repaired by Flash using +the actual Node failure. Host GPT-6 integrated the result and checked it; the +host effort setting is not exposed. + +All 16 focused reporter tests pass. Six independent CLI fixtures exercise the +exact cost boundary, missing host cost, missing elapsed time, failed quality, +higher review time and an empty draft. These are synthetic acceptance fixtures, +not measurements of the eight real task pairs. Sol/high accepted the reporter +for the repository gate after the accounting repairs. + +The four Flash calls reported 8,458 input and 29,097 output tokens, including +both rejected outputs and the test repair. Complete host/collaboration usage, +whole-task review time and attributed monetary costs remain unknown. Private +prompts, failures, review receipts and independent CLI evidence are retained in +`20260921-d5-report-9cgygyyu`.

In an + actual Codex session, check unavailable → refresh → current, edit → stale, + explicit refresh → current, and old-cursor invalidation on successful refresh. + Use a disposable fixture for deliberate edits and cancellation tests. +- Capture a pinned checkout or paired tarball launch and rollback command. + Keep keys and receipts outside the repository. Update the evidence ledger so + historical missing features are not mistaken for today's blockers. + +### D1: Establish a small daily habit + +Use the current Context checkout first. At task start, call +`repository_status`; refresh if unavailable, stale or unknown. Search for a +specific identifier with a small result budget, then read the necessary source +and tests. Page only when the task requires more evidence. Read current source +before changing it, and refresh after edits. On exclusion, no match or quota +failure, fall back to bounded `rg`/file reads and record why. + +The three tasks should cover orientation, a diagnosis and an accepted code +change. Record revision, working-tree changes, client version, model/effort, +retrievals, fallback, checks and review result. This is usability acceptance; +the paired savings experiment is D5. Start its usage record here to avoid losing +the baseline. Claude qualification can follow when its lane is available. + +### D2: Make wider repository use deliberate + +At planning time the bridge used fixed directory and extension exclusions and +did not honour `.gitignore`. Define project-local include/exclude +configuration, Git ignore semantics and how explicitly included files behave. +Test an ignored source fixture, generated directories (including Rust `target`), +hidden files, symlinks, excluded Markdown, deletion, rename and policy changes. +Never imply that honouring Git ignores constitutes secret detection. + +Use exactly the same selection policy for refresh and freshness checks. Show +exclusions and quota failures; never broaden the root automatically. Measure +refresh and per-query freshness cost on real roots: the current freshness check +reads a bounded manifest and hashes source bytes, so small output does not imply +cheap disk work. Optimise only against measured latency without losing stale +source detection. Keep the pilot confined to its reviewed root until this passes. + +### D3: Add two consumers as development repositories + +Configure separate explicit roots for KithMoot and Oathrun, each with its own +ephemeral index and client binding. Start with per-repository navigation; use +the ecosystem manifest only for a task that explicitly needs joined evidence. +Record limits, exclusions, revision and source hashes for each root. Verify a +query bound to one root cannot retrieve the other, and that disabling a binding +removes its tools on a fresh session. + +Do not use the parent workspace directory as an ambient shared root. Related +repositories do not imply permission to share private records or conversations. +This goal uses Context to work on those repositories; application/room +integration is the separate D6 goal. Keep the existing KithMoot `0.2.0` +dependency unchanged until compatibility is tested in an isolated branch. + +### D4: Remove repeated manual context assembly + +Provide a reusable packet format or small helper around the existing worker +workflow. Include task, acceptance checks, allowed files, repository/revision, +source hashes, exact relevant interfaces/fixtures, bounded excerpts, exclusions +and unresolved questions. Reject or rebuild a packet if relevant source changes. +Do not mistake a navigation pointer or Qwen summary for sufficient source. + +Scanning and excerpt assembly stay deterministic where possible. The host +reviews the packet's sufficiency once, sends ordinary implementation to Flash, +then returns precise test failures for at most one focused repair. Store the +accepted diff, checks and compact handoff rather than repeatedly sending the +whole conversation. Keep routing, execution and disclosure policy in the +consumer/worker layer; do not introduce a provider dependency into Core. + +### D5: Measure cost per accepted outcome + +Use the developer-only [whole-task cost report](TASK-COST-REPORT.md) to validate +declared controls and retain incomplete accounting explicitly. Its unlocked +template is preparation, not an executed or accepted eight-pair trial. + +Predeclare eight paired tasks: two each for orientation, bug diagnosis, change +impact and accepted code changes, distributed across at least two qualified +repositories. Compare the normal efficient `rg`/file-read workflow with Context +assistance. Hold revision, task, model, thinking/effort, tools available beyond +retrieval and acceptance checks constant within each pair. Alternate order and +use separate sessions; document cache state and possible contamination. + +Count all host and worker input/output, reported cached/reasoning usage, retries, +failed runs, tool calls, source reads, scan/refresh latency, review time and +accepted outcomes. Avoid double-counting provider reasoning fields already +included in output totals. Missing usage remains `null`; record which phase +cannot be measured. Store sensitive receipts privately and commit a sanitised +aggregate with reproducible task/acceptance definitions. + +**Proposed decision rule, to lock before running the experiment:** all eight +assisted tasks meet the same acceptance checks, with no material correctness +regression, and at least 20% lower aggregate variable inference cost per accepted +task without higher aggregate review time. Include unsuccessful-attempt costs +in each arm's numerator. Report individual pairs and total elapsed time as well +as the aggregate. Eight pairs are an operational pilot, not a universal claim. + +If billing cannot be attributed, report token/allowance changes separately and +leave the monetary gate open. Subscription headroom does not lower a fixed bill +unless it prevents overage or permits a plan change. Report cash figures in GBP +with the dated conversion basis. Only after the retrieval comparison, run a +separate experiment changing models; otherwise routing gains and retrieval gains +cannot be distinguished. If Context loses to `rg` on a task class, keep `rg` as +the default there and fix the measured cause. + +### D6: Join the ecosystem at the consumer boundary + +Coordinate with Oathrun's `docs/CHAT-CODING-DELIVERY-PLAN.md` and +`docs/CONTEXT-CACHE-PLAN.md`. Its read worker, coding executor and signed context +integration have separate gates. Begin with one scoped read task; do not build +a second worker supervisor in this repository or make full chat coding a +dependency of the local pilot. + +The consumer must select an explicit project, check authority before retrieval +and disclosure, preserve source provenance and label unsigned navigation. +Test denied cross-project reads, deliberate bounded joins, revocation on the +next read, restart and cancellation. Membership alone grants no ambient context. +Signed records and grants, rather than the local OS-only navigation process, +must carry the shared-room trust contract. Existing signed collections remain +bounded; do not persist private source in the plaintext scale prototypes. + +Close this goal with a real task in the intended Oathrun/KithMoot workflow, +including result delivery and usage evidence. A unit test, direct model call or +MCP connection check alone is insufficient. Coding can follow once Oathrun's +own execution and recovery gates pass. + +### D7: Separate reproducible adoption from public publication + +For the internal pilot, install both packages from a named commit's tarballs +outside the workspace, launch navigation against an explicit root, exercise +restart/refresh/search and document removal. No registry release is required. + +For public release, complete G0–G4, the threat model and negative-boundary +matrix, package compatibility and release documentation. Publish both matching +versions through the release process, install those exact versions from the +registry and repeat the workflow. Test the KithMoot upgrade independently before +changing its normal installation. Record prepared, published and consumer-adopted +as separate states. + +## Work to defer + +Keep encrypted persistent indexing beyond 128 signed records, ranked multi-term +retrieval, incremental large-graph refresh, hosted operation, graph editing, +automatic model routing and wider language semantics behind measured pilot +needs. The scale prototypes remain experiments. A real quota or latency failure +can promote the relevant work; synthetic corpus size alone should not delay D1. + +## Execution order and evidence + +Start D0/D1 immediately. Add minimal D5 receipts from the first normal task. +Then D2 → D3, with D4 on already-qualified roots. Run D5 comparisons before +declaring that the workflow saves money.

Create a private JSON task +specification, for example: + +```json +{ + "version": 1, + "task": "Handle an empty input in the example parser", + "acceptanceChecks": ["Run the example parser tests; empty input returns no records"], + "allowedFiles": ["src/example.ts", "src/example.test.ts"], + "sources": [{"path": "src/example.ts", "startLine": 1, "endLine": 8}], + "exclusions": ["No changes to the public protocol"], + "unresolvedQuestions": [] +} +``` + +The example paths and line range must be replaced with real evidence for the +task, including the relevant interfaces and tests. `sources` contains exact, +inclusive ranges. `allowedFiles` describes editable paths and may include new +files; source evidence can also come from files the worker must not edit. +These are task boundaries for review, not a filesystem sandbox. + +```sh +node scripts/worker-packet.mjs build \ + --root /absolute/repository --spec /private/task.json --out /private/packet.json + +node scripts/worker-packet.mjs verify \ + --root /absolute/repository --packet /private/packet.json +``` + +Verify immediately before dispatch. Changed relevant source, repository revision +or policy requires a fresh packet and another sufficiency review. Verification +is not an atomic filesystem snapshot or a signature proving authorship. + +Packets retain whole-file hashes, exact excerpts and policy provenance. Paths +must be literal and relative to the explicitly selected root. Navigation +include/exclude and Git ignore rules apply; hidden files, symlinks, generated +directories and unsupported source types are rejected. Use a separately +reviewed, bounded fallback when the task needs unsupported evidence. Do not +silently broaden the root or policy. + +The helper refuses to overwrite an output and writes it with private file +permissions. The complete JSON packet must fit within 64 KiB; reduce the task +or choose smaller sufficient excerpts if it does not. There is no silent +truncation. Source text remains untrusted data, even when its hash matches. + +Review the packet's sufficiency, choose the worker explicitly, and record the +initial draft, any repair, actual checks and review outcome. Preserve the +accepted diff and a compact handoff. Count host work, failed attempts and review +alongside worker usage; packet size alone does not establish a monetary saving. +See the [model assignments and whole-task comparison](FORGESWORN-DOGFOOD-GOALS.md). diff --git a/docs/examples/task-cost-draft.json b/docs/examples/task-cost-draft.json new file mode 100644 index 0000000..b9334e4 --- /dev/null +++
