Rebuild thread-label stall — Railspike debug log

2026-10-13 03:07:02 UTC — Step 1

Debug mode: enabled by the user's explicit request, recorded in the Step 1 artifact.

Necessary/useful instructions

• docs/railspike/docs/workflow/step1_solution_assessment.md, Structure: comparing options and recording a recommendation separated progress-only remediation from batching and broader optimization. Retain; these are materially different scopes.

• docs/railspike/RAILSPIKE.md, Repository Boundary and Planning Artifacts: placed this assessment and log in the host project's docs/plans/, outside the vendored workflow. Retain to avoid modifying the upstream subtree.

• docs/railspike/RAILSPIKE.md, Railspike Debug Mode / Durable state and recovery: the explicit enable request resolved state without clarification; the artifact records it for later steps. Retain.

• docs/railspike/docs/workflow/step1_solution_assessment.md, Next: the Step 1 boundary kept this task to investigation and assessment, with no implementation, commits, or production rebuild. Retain.

Redundant/unnecessary instructions

• docs/railspike/RAILSPIKE.md, How to Use This Chain item 2 and Key Rules instruction to reprint: printing the entire Step 1 instruction file added substantial conversation output before a short assessment; the file had already been read and is linkable. Consider replacing the full reprint with a source link and brief statement of the active step. The reprint was performed as required.

Inapplicable instructions

• docs/railspike/RAILSPIKE.md, Step 4 commit cadence and organization gate: no Step 3 approval or implementation exists in this cycle. Leave both new files uncommitted in docs/plans/; apply organization and commits at their prescribed later gate.

Uncertain assessments

• The Step 1 one-page limit favors brevity, but source evidence is needed to distinguish a confirmed progress gap from a suspected production bottleneck. A short evidence section supports that distinction; rendered page length was not measured. Consider explicitly allowing a compact evidence/uncertainty section for diagnostic assessments.

2026-10-13 03:13:27 UTC — Step 1 Revision

This entry supplements the initial report and supersedes its label-only scope assessment. Debug mode remains enabled.

Necessary/useful instructions

• docs/railspike/docs/workflow/step1_solution_assessment.md, Review and revision: the user's additional symptom expanded the current assessment without implying approval or advancing to Step 2. Preserving Original Query and adding Revised scope retained both requests. Retain.

• docs/railspike/RAILSPIKE.md, scope and vertical-slice rules: distinguished the three matching source-history patterns from broader algorithmic candidates; the recommendation includes observable rebuild completion and recovery. Retain to keep discovery from becoming an unbounded implementation plan.

• docs/railspike/RAILSPIKE.md, Persistent debug log: appended this revision without rewriting the earlier evidence. Retain.

Redundant/unnecessary instructions

No new supported findings; the original report's instruction-reprint observation remains applicable.

Uncertain assessments

• The one-page guidance becomes harder to meet when a requested cross-phase audit must distinguish confirmed repeated operations from unmeasured performance. The revised assessment uses compact grouped findings; retain brevity but clarify how diagnostic inventories should fit without losing uncertainty or scope boundaries.

2026-10-13 04:42:49 UTC — Step 2

Debug mode: enabled, inherited from approved Step 1. User approval authorized this feature description; application work and commits remain deferred.

Necessary/useful instructions

• docs/railspike/docs/workflow/step2_feature_description.md, Structure / Completion boundary: made candidate validation, promotion, snapshot readiness, and recovery explicit rather than ending the feature at faster indexing. Retain.

• Same file, Risks and Success criteria: separated measurable history-query reduction from an unsupported production speedup promise; specified earliest validation and mitigation for provenance and reporting risks. Retain.

• Same file, Shared component inventory: identified the CLI and existing optional reporting path as the surfaces to extend, preserving forum/API/offline consumers. Retain with applicability-based detail.

• docs/railspike/RAILSPIKE.md, Debug Mode and Commit discipline: inherited durable state, appended this report, and left planning artifacts uncommitted. Retain.

Redundant/unnecessary instructions

• docs/railspike/RAILSPIKE.md, instruction-reprint rule: again required printing a full workflow file before a concise deliverable, duplicating the accessible linked source. Consider a link plus brief active-step statement; the required reprint was performed.

Inapplicable instructions

• Step 2's documentation-only scope requirements do not apply: this description explicitly plans an application change, although the current deliverable is a planning document.

Uncertain assessments

• Step 2 asks for risk mitigation “before Step 3” while deferring implementation planning and verification. This artifact states the validation and mitigation obligations without claiming they have run. Clarify whether the phrase requires completed empirical checks or documented mitigations at this planning gate.

2026-10-13 04:53:54 UTC — Step 3

Debug mode: enabled, inherited from approved Step 2. No implementation, branch creation, or commits performed.

Necessary/useful instructions

• docs/railspike/docs/workflow/step3_development_plan_do.md, Completion Contract and Key Risks: explicitly tied release to normal CLI completion, data parity, candidate protection, and snapshot retry behavior. Retain; reporting changes can otherwise obscure failures.

• Same file, stage dependencies and verification: placed baseline capture before edits and provenance checks before extending batching; each stage has an explicit verification/commit boundary. Retain.

• docs/railspike/docs/workflow/step3_development_plan_after.md, checklist: prompted a concision pass to 583 whitespace-delimited words and verification of all six required fields in five stages. Retain the field audit.

• docs/railspike/RAILSPIKE.md, commit discipline: approval of Step 2 authorized planning, while implementation and planning commits remain behind Step 3 approval. Retain.

Redundant/unnecessary instructions

• The three Step 3 phase files and RAILSPIKE.md repeat state restoration, reprinting, and approval boundaries. This step required three instruction reprints before delivering one plan. Consider consolidating conversation reprints to one linked step summary while retaining phase checks; all required phase reprints were performed.

Inapplicable instructions

• Planned database/function-signature updates are unnecessary: existing optional reporters and helper contracts cover the proposed work. The plan states that signatures and schema remain unchanged rather than inventing new interfaces.

Uncertain assessments

• The one-page requirement has no page-size/rendering definition and competes with six required fields per stage. The final artifact is compact at 583 words but physical pagination was not verified. Clarify a word budget or prioritize complete risk/verification fields over rendered page count.

• About one hour per stage is an estimate, not measured feasibility; fixture and failure-path complexity may require splitting a stage before implementation. The plan records that obligation and remains below the eight-stage/day ceiling.

2026-10-13 05:14:21 UTC — Step 4

Debug mode: enabled, inherited into the implementation summary. This is the single completed Step 4 report; stage evidence lives in the summary.

Necessary/useful instructions

• docs/railspike/docs/workflow/step4_implementation_before.md, Planning Docs Commit Gate: produced 686d8766 containing only approved plans, the preserved debug log, and organization/index changes, before summary or code creation. Retain; the boundary is directly auditable.

• docs/railspike/docs/workflow/step4_implementation_do.md, Stage Boundary Protocol: each of the five stage commits includes its summary update and verification evidence. The provenance stage caught a real merge-resolution mismatch before batching expanded to other families. Retain.

• docs/railspike/docs/workflow/step4_implementation_after.md, normal-flow/recovery verification: drove actual ./v3 rebuild coverage and validation, sidecar, lock-timeout, and post-promotion snapshot failure checks. Retain; direct builder timing alone would not establish delivery.

• docs/railspike/RAILSPIKE.md, Persistent debug log: allowed this final log-only handoff commit without rewriting stage history. Retain.

Redundant/unnecessary instructions

• RAILSPIKE.md and the Step 4 phase files, instruction-reprint requirements: three more full workflow reprints added conversation volume while source links, stage updates, and the persistent summary already made the active process reviewable. Consider one linked step summary instead; required reprints were performed.

Inapplicable instructions

• Documentation-only scope clauses and database-migration verification do not apply: this is an application change with no schema changes. Production deployment is explicitly outside the approved scope.

Uncertain assessments

• The final verification gate does not specify how to distinguish pre-existing suite failures from feature failures or how to handle an environment change after a completed run. Nine failures were reproduced on pre-change code; the one feature-related stale-output assertion was corrected and its targeted run passed. The summary records the non-green repository-wide release gate and PHP disappearing before the requested clean rerun. Clarify evidence requirements for this case rather than implying either unqualified success or authorization to fix unrelated features.

• The Stage 3 one-hour/line-count estimates understated source-line churn from consistently wrapping existing loops, but the stage remained one coherent behavior change with parity checks and a separate commit. Consider sizing by verification scope and dependencies rather than line count for instrumentation work.
