Username change gate — Railspike debug log

2026-10-16T12:41:42Z — Step 1

Debug mode: enabled (new workflow; project-root .railspike_debug_on file present).

Necessary/useful instructions

  • docs/railspike/docs/workflow/step1_solution_assessment.md, Structure: preserving the Original Query verbatim and adding Understood Intent made it possible to note that "two ways" lists three items without silently rewriting the request. Retain.

  • docs/railspike/RAILSPIKE.md, Debug Mode: marker-presence rule resolved the mode without asking. Retain.

Redundant/unnecessary instructions

  • docs/railspike/RAILSPIKE.md, How to Use This Chain and Key Rules repeat the approval-gate and instruction-reprint rules also stated in the Step 1 file. Consolidate into one authoritative location.

Inapplicable instructions

  • Guardrail "no implementation details" sits in tension with naming registry/endpoints needed to make the options distinguishable; kept to the minimum.

Uncertain assessments

  • Whether the "≤1 page" limit holds once the Understood Intent and open decisions are included; assessed as borderline.

2026-10-16T13:04:44Z — Step 2

Debug mode: enabled, inherited from Step 1 and recorded in Step 2.

Necessary/useful instructions

  • docs/railspike/docs/workflow/step2_feature_description.md, Shared component inventory: enumerating every activity consumer (page, Forte, RSS, detail, manifest, SQLite catalog) exposed how widely a new activity kind reaches. Retain.

  • docs/railspike/docs/workflow/step2_feature_description.md, Risks with earliest validation: led to naming the real local record as the rebuild test case. Retain.

Redundant/unnecessary instructions

  • No supported findings.

Inapplicable instructions

  • Documentation-only scope fields: work type is an application change.

Uncertain assessments

  • The one-page limit is tight once the inventory spans many activity surfaces; assessed as borderline.

2026-10-16T13:05:52Z — Step 3

Debug mode: enabled, inherited from Step 2 and recorded in Step 3.

Necessary/useful instructions

  • docs/railspike/docs/workflow/step3_development_plan_after.md, stage-sizing check: caught that one stage spanned six activity surfaces and led to splitting it. Retain.

  • docs/railspike/docs/workflow/step3_development_plan_do.md, Key Risks with High risk prefixes: forced the rollback and flag-off relabelling risks to the top. Retain.

Redundant/unnecessary instructions

  • Before/do/after phase files repeat the debug-state and uncommitted-docs rules already in RAILSPIKE.md. Consolidate.

Inapplicable instructions

  • Documentation-only completion-contract variant.

Uncertain assessments

  • The one-page limit is not realistic for a seven-stage plan with full stage fields; the plan runs longer than one page.

2026-10-16T14:13:21Z — Step 4

Debug mode: enabled, inherited from Step 3 and recorded in the Step 4 summary.

Necessary/useful instructions

  • docs/railspike/docs/workflow/step4_implementation_do.md, Stage Boundary Protocol: running verification and committing per stage localized the two real defects (SQLite text-versus-integer binding in Stage 6; the key-generation test flake in Stage 4) to single commits. Retain.

  • docs/railspike/docs/workflow/step4_implementation_before.md, Planning Docs Commit Gate: separating the plans commit kept the research report and todo.txt out of it until their stage. Retain.

  • docs/railspike/RAILSPIKE.md, organization rule: moving the plans into one folder and fixing the report link was mechanical and prevented a dangling relative link. Retain.

Redundant/unnecessary instructions

  • The Step 4 before/do/after files and RAILSPIKE.md each restate the commit-cadence and no-amend rules. Consolidate into one location with references.

Inapplicable instructions

  • Documentation-only verification variants and deployment/migration dependency checks (no deployment in scope; the flag ships off).

Uncertain assessments

  • "Log-only handoff commit" versus finalizing the Step 4 summary: the summary was finalized in the last stage commit, so the handoff commit touches only this log; unclear whether a final summary note belongs in the handoff commit.

  • The planned eight-stage ceiling and "about one hour per stage" were met in count, but Stage 5 and Stage 6 each took longer than a one-hour estimate because of the number of activity consumers.
