2026-10-25T22:41:57Z — Step 1

Necessary/useful instructions

Source: docs/railspike/docs/workflow/step1_solution_assessment.md — compare alternatives and stop before Step 2. Observation: Distinguished a bounded contention fix from cache lifecycle work and cosmetic-only recovery; the production cause remains explicitly unconfirmed. Suggestion: Retain comparison and approval boundary.

Source: docs/railspike/RAILSPIKE.md — Experimental Effort Estimation. Observation: Recorded prior diagnostic exposure, verified frozen R1 hashes, and retained separate whole-cycle alternative estimates under standing enrollment. Suggestion: Retain exposure and non-additivity requirements.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Source: docs/railspike/RAILSPIKE.md — Step 4 commit cadence. Observation: This request produces Step 1 only; no branch, implementation or commit is due. Suggestion: Retain as a later-step requirement.

Uncertain assessments

Source: docs/railspike/docs/workflow/step1_solution_assessment.md — one-page limit. Observation: Required navigation and study snapshots add length to an otherwise concise three-option assessment; rendered page count depends on the viewer. Suggestion: Clarify whether study metadata is outside the comparison page budget.

2026-10-26T00:28:58Z — Step 1 revision

Necessary/useful instructions

Source: docs/railspike/docs/workflow/step1_solution_assessment.md — Review and revision. Observation: User selection of B revised recommendation and recovery scope without advancing to Step 2; Original Query retained. Suggestion: Retain distinction between selecting an option and approving a step.

Source: docs/railspike/RAILSPIKE.md — Experimental Effort Estimation. Observation: Preserved v1/A 0.45 and recorded v2/B 0.90 with user-directed scope change, same baseline and verified R1 sources. Suggestion: Retain append-only estimate history.

Redundant/unnecessary instructions

No supported findings.

Uncertain assessments

Prior page-budget observation remains unchanged; no new finding.

2026-10-26T00:35:42Z — Step 2

Necessary/useful instructions

Source: docs/railspike/docs/workflow/step2_feature_description.md — Known user or environment / Completion boundary. Observation: Separated local route/browser acceptance from qdb.us recovery, whose lock holder remains unidentified; specified unaided retry and matching-artifact recovery. Suggestion: Retain named-environment evidence requirement.

Source: docs/railspike/docs/workflow/step2_feature_description.md — Shared component inventory / Risks. Observation: Captured shared delivery cleanup and importer compatibility, plus stale-archive and active-transfer risks before implementation planning. Suggestion: Retain explicit shared-surface and early-risk review.

Redundant/unnecessary instructions

No supported findings.

Uncertain assessments

The prior one-page budget concern persists with mandatory study metadata and named-environment requirements; no new recommendation.

2026-10-26T00:57:42Z — Step 3

Necessary/useful instructions

Source: docs/railspike/docs/workflow/step3_development_plan_do.md — Key Risks and canonical contracts. Observation: Made stale-content admission and current send/shutdown deletion explicit prerequisites; planned protected delivery before cleanup. Suggestion: Retain risk dependencies and shared-contract inventory.

Source: docs/railspike/docs/workflow/step3_development_plan_after.md — stage estimates and handoff gate. Observation: Six stable stages have original work estimates, shared acceptance ownership and a separately judged cycle total; implementation remains gated. Suggestion: Retain non-additivity and approval requirements.

Redundant/unnecessary instructions

No supported findings.

Uncertain assessments

Source: Step 3 Do/After — one-page limit and mandatory per-stage fields. Observation: Six stages with required risk, contract, estimate and verification fields exceed a conventional printed page. Kept each stage compact rather than dropping mandatory safety/verification details. Suggestion: Define the page budget excluding required study metadata or permit a stage-proportional limit.

Source: Step 3 Do — approximate one-hour stage sizing. Observation: Stages isolate contracts and outcomes, but timing cannot be established before implementation; oversized stages require splitting before dependent work. Suggestion: Retain explicit sizing review without representing projections as measured duration.

2026-10-26 — Step 4 completed-step report

State: Debug enabled; six stages locally complete; production/maintainer acceptance pending. Commits: Planning 3256d774; S1 7c4a5e91; S2 84f14eee; S3 cf7cb4e1; S4 58c57cd3; S5 f9fd15b8; S6 94a55e68. Seven commits satisfy planning-plus-six-stages cadence; summary introduced only after planning commit. This report is the separate log-only handoff commit. Verification: Final targeted run 33/34 with identical baseline filename-test failure reproduced in isolated starting-revision archive; final strengthened checks 3/3; real HTTP/browser acceptance passed. Navigation links and diff whitespace passed. No dependency/manifest/lock/vendor or todo.txt changes; clean worktree before this log addition. Deployment, qdb.us process ownership/recovery, full suite and physical devices unverified. Study: R1/P2, v2/Option B, original baseline and estimates retained. Projected 0.90; separate retrospective 0.95, no labor measurement or maintainer acceptance invented.

Necessary/useful instructions

Source: docs/workflow/step4_implementation_do.md — stage boundary protocol. Observation: Separate commits preserved freshness, protected delivery, bounded coordination, response semantics, storage recovery and acceptance. Test fixture lock inheritance and old 409 assertions were corrected before advancing. Suggestion: Retain verification-plus-summary commit gates.

Source: docs/workflow/step4_implementation_after.md — final verification checklist, items 5–7. Observation: Prevented local reuse/performance results from being presented as qdb.us recovery and required reproducing the legacy filename-test failure rather than claiming a green suite. Suggestion: Retain environment-specific evidence and explicit baseline-failure reporting.

Source: RAILSPIKE.md — experimental effort estimation. Observation: Preserved stage originals and separately recorded acceptance corrections as retrospective scope, without adding stage scores or treating runtime benchmarks as effort measurements. Suggestion: Retain scope/exposure/non-additivity rules.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Source: docs/workflow/step4_implementation_before.md — eligible existing-branch reuse. Observation: New feature branch created; no branch reuse was requested or needed. Suggestion: Retain conditional rule for follow-up cycles.

Uncertain assessments

Source: docs/workflow/step3_development_plan_do.md — approximate stage sizing. Observation: Lifecycle and acceptance required more than the alternative 50-line guideline; stages remained distinct tested outcomes. Reliable active-work timing is unavailable, so no hour-limit compliance measurement is claimed. Suggestion: Clarify the relationship between approximate line-count and outcome-based stage sizing.
