Feature plan: Step 1 · Step 2 · Step 3 · Step 4

Debug mode: enabled Effort study: railspike-effort / v3/agent_response_text — ledger Extended estimates: enabled

Cycle estimate: 0.70

Execution entry

Approved Step 3 received. Branch feature/agent-response-text; planning commit 36abf44c. Scope v2/A, baseline 9005e87611b82e2304c0be52505d994674dc4efa, R1/P2; Codex single exposed rater. 2026-10-29 UTC entry projection 0.70 reaffirmed before implementation. S1–S5/v1 stage-work originals 0.15/0.15/0.12/0.15/0.15, non-additive; S5 owns shared acceptance. No measured labor. Prior intake/v1 0.65 retained. Zero dependencies planned; no production mutation, actual legacy removal or deployment.

Stage 1 - Compatible canonical metadata

Original estimate: 0.15 Retrospective stage-work assessment: 0.15

• Changes: Named header codec, isolated legacy canonical decoder, shared validation independent of machine JSON/storage, post parser wiring, format contract and touched concept entries. Generic duplicate handling reused; old empty-header/extra-field interpretation preserved. Writers switch in S2.

• Verification: php tests/run.php AgentResponseMetadataTest CanonicalRecordParsersTest: 50/50. Old/new normalized metadata and source hash equivalence, retained historical input bytes, malformed/mixed/unknown/duplicate declarations, ordinary/empty legacy metadata checked.

• Notes: No stage estimate revision or dependency/schema delta. Actual signed publication verification follows in S2.

Stage 2 - Signed generation and expansion

Original estimate: 0.15 Retrospective stage-work assessment: 0.15

• Changes: Shared reply writer emits named headers before signing. Added actual request/fulfillment coverage for new signed generation and expansion of a signed historical initial.

• Verification: Five focused WriteApiSmokeTest methods (readable signed legacy expansion, request/publication/rebuild, provenance/replay, changed/hidden source rejection, failure/retry/source race): 5/5 passed. Verified both detached signatures; legacy record and signature remain byte-identical after expansion and replay. Existing soft-reset test covers interrupted commit recovery.

• Notes: Initial test run caught a missing qualified class name in the writer; corrected before passing. No estimate revision, dependencies, schema or publication policy changes.

— Codex · 2026-10-29 UTC

Stage 3 - Rebuild, transfer and offline compatibility

Original estimate: 0.12 Retrospective stage-work assessment: 0.15

• Changes: Added four signed old/new initial-expansion combinations through full rebuild, source view, content export, real CLI import, imported presentation and offline snapshot; clarified canonical and read-model specs. Existing consumers need no production changes.

• Verification: Three focused WriteApiSmokeTest methods (readable transfer, legacy transfer matrix, cache/offline visibility): 3/3 passed. Incremental metadata equals rebuilt/imported/offline metadata; exported/imported record and signature bytes match. Existing offline visibility check rejects changed versions.

• Notes: Content-download archive wrapper is repository/; existing content-import interface accepts records/ or local_repository/records/. Test uses the established extraction/repack procedure, preserving record bytes. Direct download-wrapper import is outside this format change. Retrospective reflects the transfer fixture work; original estimate retained, no prospective revision. No dependencies or schema change.

Stage 4 - Retirement inspection and removal proof

Original estimate: 0.15 Retrospective stage-work assessment: 0.15

• Changes: Read-only format-readiness scanner/CLI, default named text and explicit JSON, top-level/subcommand help, dependency listing and future removal guide. Existing bounded canonical reads; two content-hash inventories conservatively detect observable change. No initialization/rebuild/conversion.

• Verification: php tests/run.php AgentResponseFormatReadinessTest: 3/3. Actual CLI exit 0/1/2, output parity, no file-content writes, dated/flat paths, mixed headers, missing directory, symlink, duplicate ID and injected concurrent addition checked. Fresh PHP process blocks the legacy adapter while normal new generation/expansion, signing, rebuild, export/import child process and offline export pass; old input explicitly fails. PHP lint/help and diff checks pass.

• Notes: Stop writers for an atomic operational snapshot; two passes cannot detect reverted transient changes. History/archives always unknown. Adapter removal remains unauthorized. Estimates unchanged prospectively; no dependencies or schema changes.

Stage 5 - Acceptance and closeout

Original estimate: 0.15 Retrospective stage-work assessment: 0.15

• Changes: Extended existing browser fixture to inspect raw source and offline rendering at both widths; distinguished complete-but-invalid inspection from unreadable/incomplete coverage. Added unreadable/oversized/missing-dependency regressions. Updated checklist, navigation, references and study closeout.

• Verification: 90/90 focused PHP checks across AgentResponseMetadataTest, AgentResponseFormatReadinessTest, CanonicalRecordParsersTest, AgentReplyGenerationTest, AgentReplyCommandTest, PublicOfflineSnapshotBuilderTest, OfflineSnapshotThreadPresentationTest and 13 relevant WriteApiSmokeTest methods. After scanner review, its expanded four tests pass 4/4 (overlap, not 94 distinct tests). These cover real request/fulfillment, signed initial/expansion, permissions, stored-draft recovery, retry/replay, stale/hidden sources, all four representation combinations, full/incremental projection and actual CLI import/offline export.

• Browser: node tests/browser/scripture_expansion.cjs passes thread and post at 375/1280 pixels; source and offline at both widths. Checked request/progress, safe content, keyboard disclosure, stored results, overflow after expansion, no offline generation controls, schema upgrade and unavailable-source updates. The fixture is produced by actual generation/expansion; browser APIs are intercepted. Initial added source check incorrectly served raw text as HTML and applied app-layout assertions; corrected to the route's text/plain contract. Native raw-text viewer wrapping is browser-controlled.

• Notes: No UI markup, copy, icon or theme changes. Default fixture theme only; no all-theme, physical-device, live-provider quality, full-suite or deployment claim. Zero added/updated third-party components, manifests or locks; no read-model schema/query change. Touched concept entries match implementation and source paths. No todo.txt changes. Estimates unchanged prospectively.

Study closeout and release limits

Cycle estimate: 0.70 (entry reaffirmed; no in-cycle revision) Retrospective whole-cycle scope assessment: 0.75

Scope v2/A, original baseline, R1/P2 and single exposed Codex rater retained; frozen reference hashes reverified. The separate retrospective reflects signed transfer matrix and removal-proof verification work; original intake/v1 0.65 and all projected/stage values remain preserved. S1–S5 original/retrospective values: 0.15/0.15, 0.15/0.15, 0.12/0.15, 0.15/0.15, 0.15/0.15 (non-additive). Measured labor remains unknown; maintainer acceptance/fit pending, no accepted-count increment. No new enhancement or scope change during execution.

F05 is technically complete locally. Planning 36abf44c; stages 1–4 af2ea2a5, c3a58ee2, f24b6eff, 4890dc6d; this closeout accompanies stage 5. No merge/push, production mutation, historical conversion or actual reader retirement. Readiness requires quiescent input for a reliable snapshot and does not inspect history or external archives. The checklist now has 5 complete / 11 open; F04 is next among canonical conversions and requires a separate cycle.

Documentation check: New/changed cycle links resolve and checklist counts are 5/11. The ledger contains one pre-existing unrelated broken link to thread_unpin_web_ui_step1_solution_assessment.md (present at baseline); left unchanged. Whitespace and dependency-file inventory checks pass.

Merge verification

2026-10-29 UTC: User authorized merge and push. Integrated with origin/main 3c404b30; overlapping additions in the plan index and effort ledger were combined, preserving both cycles' entries. Code merged without conflicts. Combined-tree verification passed: 61/61 focused parser/readiness/signed-generation/transfer/ expansion/retry checks, plus Chromium thread/post/source/offline at 375/1280 pixels. No full-suite or deployment claim. Earlier local-only release limits are historical; legacy-reader retirement and production conversion remain outside this merge.
