Legacy backup compatibility — Railspike debug log

2026-10-20 — Step 1

UTC date: 2026-10-20. Exact report time was not captured.

Necessary/useful instructions

  • Source: docs/railspike/docs/workflow/step1_solution_assessment.md, Objective and Deliverable. Comparing reuse of the legacy loader with timestamp-independent scanning exposed a validation-boundary decision before implementation. Retain this comparison requirement.

  • Source: docs/railspike/RAILSPIKE.md, Commit discipline. The assessment remains uncommitted and application code is unchanged; retain the explicit distinction between diagnosis and implementation authorization.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

  • Source: docs/railspike/RAILSPIKE.md, Experimental Effort Estimation. This cycle was not selected for the study; no estimates were generated.

Uncertain assessments

  • Source: docs/railspike/docs/workflow/step1_solution_assessment.md, Next. Approval adds a handoff to a bug investigation that has a small local reproduction, but choosing the backup validation boundary warrants review. Insufficient evidence to recommend changing the gate.

2026-10-20T22:35:00Z — Step 2

Necessary/useful instructions

  • Source: docs/railspike/docs/workflow/step2_feature_description.md, Known user or environment. Requiring the named environment distinguishes local regression coverage from proof that zenmemes.com and the user's WSL import have recovered. Retain this explicit evidence boundary.

  • Source: the same file, Risks and Shared component inventory. These requirements keep legacy date provenance, image integrity, and bounded error handling visible before implementation planning; retain them.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

  • Source: the same file, documentation-only delivery scope. This is application work, so the documentation-only runtime prohibition does not apply.

Uncertain assessments

  • Source: the same file, Deliverable and Structure. The one-page target competes with named-environment recovery, full shared-surface inventory, and risk mitigation detail; the artifact remains concise, but printed pagination was not verified. No process change is proposed from this single case.

2026-10-20T22:40:21Z — Step 3

Necessary/useful instructions

  • Source: docs/railspike/docs/workflow/step3_development_plan_do.md, Key Risks and early validation. Inspecting the legacy loader before planning exposed its filesystem-date fallback; the plan explicitly restricts that fallback for backup use while preserving other callers. Retain risk-first planning.

  • Source: the same file, known-environment acceptance requirement. Stage 4 retains the named source/WSL replay and manual handoff rather than substituting local HTTP passes. Retain the evidence distinction.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

  • Source: the same file, documentation-only scope. Runtime changes were approved in Step 2, so documentation-only restrictions do not apply.

Uncertain assessments

  • Source: docs/railspike/docs/workflow/step3_development_plan_after.md, stage sizing and one-page checklist. Four stages separate compatibility, diagnostics, HTTP acceptance, and operations; test fixture work may require splitting a stage. Printed page count was not verified. Preserve explicit stage sizing review before implementation rather than claiming measured duration.

2026-10-20T22:53:03Z — Step 4

Necessary/useful instructions

  • Source: docs/railspike/docs/workflow/step4_implementation_do.md, Stage Boundary Protocol. The planning commit and four stage commits each preserve their verification and summary boundary. This made the local fix, regression proof, and operator handoff reviewable separately; retain the protocol.

  • Source: docs/railspike/docs/workflow/step4_implementation_after.md, Final Verification Checklist 7. Reporting baseline failures and named-user evidence separately prevented 1372 passing tests from being represented as a green full suite or live incident recovery. Retain the explicit evidence requirements.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

  • Source: docs/railspike/RAILSPIKE.md, Experimental Effort Estimation. This cycle was not selected; no scoring or ledger updates were performed.

Uncertain assessments

  • Source: docs/railspike/docs/workflow/step3_development_plan_do.md, stage sizing. Stage 1 and Stage 3 test changes exceeded the approximate line target while remaining focused on their approved outcome. Line count alone was a poor indicator of fixture complexity; the one-hour sizing target and stage scope remained useful. Consider clarifying that fixture/test lines do not independently demand splitting a releasable slice.

  • Source: docs/railspike/docs/workflow/step4_implementation_after.md, log-only handoff commit. This report uses the required separate commit after the four implementation stages; its benefit relative to a final-stage report is not established from one cycle. No workflow change is proposed here.
