Unified removal format — Railspike debug log

2026-10-29T00:03:48Z — Step 1

Necessary/useful instructions

  • docs/railspike/docs/workflow/step1_solution_assessment.md, options and recommendation: comparing a shared format with the narrower F02 conversion made the additional retraction compatibility and verification scope explicit. Retain.

  • docs/railspike/RAILSPIKE.md, Experimental Effort Estimation: preserving the earlier exposed screening estimate separately avoids presenting changed scope as a measurement or overwriting history. Retain.

Redundant/unnecessary instructions

No supported findings.

Uncertain assessments

  • The 0.75 projection remains provisional until same-post operation transitions and interrupted writes are specified. This is application-scope uncertainty, not evidence that the workflow instructions need changing.

2026-10-29T00:13:16Z — Step 2

Necessary/useful instructions

  • docs/railspike/docs/workflow/step2_feature_description.md, completion boundary and shared component inventory: required ordinary retraction/deletion/repair outcomes and recovery rather than declaring a codec-only change complete. Retain.

  • Same source, risks before Step 3: surfaces same-post evidence precedence and unsupported pending journals before selecting storage/write mechanics. Retain.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

  • Same source, named user/environment condition: no particular deployed instance or user was named for implementation. No production acceptance or deployment was invented.

— Codex · 2026-10-29 UTC

2026-10-29 UTC — Step 3

Necessary/useful instructions

  • docs/railspike/docs/workflow/step3_development_plan_do.md, Key Risks and stage dependencies: exposed array-union precedence and pending-journal replay as prerequisites to switching writers; retain early-risk resolution.

  • Same source, extended stage estimates: identifies shared acceptance as S7's responsibility while retaining a separately judged whole-cycle revision. Retain.

Redundant/unnecessary instructions

No supported findings.

Uncertain assessments

  • Step 3's one-page limit and required per-stage fields compete for space in seven-stage integration plans. This plan favors the required verification/risk fields over a literal printed-page limit. Clarify the intended compactness measure or permit a concise summary plus stage detail. No implementation authority is inferred from that formatting choice.

— Codex · 2026-10-29 UTC

2026-10-29 UTC — Scope v2 revision, Steps 1–3

Necessary/useful instructions

  • RAILSPIKE.md, scope protection and effort snapshot history: retain original scores while documenting the user's explicit removal of old-format compatibility. This distinguishes reduced scope from a claim of measured efficiency; retain.

Redundant/unnecessary instructions

No supported findings.

Uncertain assessments

  • No additional approval of the narrowing is needed: the user directly instructed it. Step 3 implementation approval remains pending. The revision removes legacy recovery obligations rather than adding another compatibility layer.

2026-10-29 UTC — Step 4 completed handoff

Necessary/useful instructions

  • Step 4 Do, stage-boundary verification and scoped commits: separated codec, interpretation, two writer paths, archive wiring and maintenance before final acceptance. The stronger normal-flow recovery test exposed a staged-deletion retry bug that component format checks did not catch. Retain the ordinary-flow completion contract.

  • Experimental Effort Estimation, original versus retrospective assessments: preserved the user-approved compatibility reduction and recorded final recovery correction separately from the 0.70 projection. Retain.

  • Step 4 Before, planning commit gate: commit 5143ab6f contains only organized approved plans/debug history/index; the summary begins in S1. Retain.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

  • Deployment and external-user recovery: excluded by the approved completion contract. No production deployment, old-data migration or physical-device acceptance was inferred.

Uncertain assessments

  • Seven stages completed with required normal-flow evidence; whether 0.75 retrospective scope comfortably fit remains the maintainer's judgment, not an automatically accepted study outcome.

  • Earlier stage-sizing/page-length concerns remain recorded; no instruction changes were made during this cycle.
