Account key approval safety — Railspike debug log

2026-10-16 20:01:21 UTC — Step 4 completed handoff

Debug mode: enabled. This report covers the observed Stage 6 resumption and the final artifact/history checks; it does not reconstruct unobserved earlier conversations.

Necessary/useful instructions

• Source: RAILSPIKE.md, Durable state and recovery; step4_implementation_do.md, Execution Rules. The existing summary preserved enabled debug state and clearly identified unfinished Stage 6, allowing interrupted work to resume without recreating the plan. Retain this recovery requirement.

• Source: step4_implementation_do.md, Stage Boundary Protocol. Recording verification and changes in the same stage commit produced an auditable Stage 6 result (e48ac882) alongside the existing five stage commits. Retain stage-scoped summary and commit requirements.

• Source: step4_implementation_after.md, Final Verification Checklist, items 4–5. Checking end-to-end recovery and deployment scope prompted isolated repeated rebuild/static/status/audit verification while preserving production authorization boundaries. Retain the contract and environment checks.

Redundant/unnecessary instructions

• Source: RAILSPIKE.md, How to Use This Chain and Key Rules; Step 4 phase files. Repeated navigation, reprint, and commit-cadence directions add reading overhead on resumption despite the already completed branch/planning setup. Consolidate the shared requirements and provide a concise resumption entry point while retaining gates.

Inapplicable instructions

• Source: step4_implementation_before.md, Planning Docs Commit Gate. Creating a new feature branch and planning commit was inapplicable to this resumption: the existing branch, planning commit febc1e03, and stage history already established that state. Verified existing evidence instead of repeating setup.

• Source: step4_implementation_do.md, documentation-only verification. This approved slice includes source, tests, browser flows, and documentation, so the documentation-only boundary did not apply.

Uncertain assessments

• Source: RAILSPIKE.md, explicit step approval gates. Earlier approval messages are outside the available resumed conversation. The committed approved planning artifacts, five implementation stages, and the user's explicit request to continue interrupted work support resuming Stage 6; this report cannot independently attest to the original approval wording. Consider recording approval provenance in the durable workflow state for future resumptions.
