Concurrent checkouts debug log

2026-10-23T06:09:41Z — Step 1

Necessary/useful instructions

• docs/workflow/step1_solution_assessment.md, Objective and Review: comparing alternatives exposed the worktree assumption; the user clarification changed the recommendation before implementation. Retain.

• RAILSPIKE.md, planning approval gates: kept active checkouts intact while assessing options. Retain.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Step 4 branch and stage-commit requirements do not apply to this assessment.

Uncertain assessments

Effort snapshot bookkeeping adds work to a small operator-workflow discussion; missing frozen references prevent numeric calibration. Keep required records and assess overhead over multiple cycles rather than claiming redundancy from this case.

2026-10-23T06:27:07Z — Step 1 revision

Necessary/useful instructions

• Step 1 Review and revision: preserving the initial assessment while revising the recommendation captured the user's actual IntelliJ workflow. Retain.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Stage implementation and commit cadence remain inapplicable.

Uncertain assessments

Revision of the earlier reference-availability finding: report/diff are present and match frozen hashes; feedback differs. Numeric calibration remains unavailable. Earlier missing-reference statement was not a verified current inventory and must not be treated as such.

2026-10-23T06:34:57+00:00 — Step 1 v3

Necessary/useful instructions

• Step 1 Review and revision: captured the synchronization clarification and replaced the earlier identification-only recommendation without treating conversational agreement as implementation approval. Retain explicit scope review.

• RAILSPIKE.md Enhancement Requests: preview/apply and recovery are recorded before implementation. Retain.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Step 4 branching, artifact commits and runtime verification are not applicable to the current assessment.

Uncertain assessments

The exact-phrase approval requirement adds a round trip after plain-language agreement. Follow the requirement; consider whether future workflow revisions can accept unambiguous direction-specific approval while retaining implementation boundaries. No workflow changes made.

2026-10-23T07:44:54+00:00 — Step 1 v4

Necessary/useful instructions

• Step 1 Review and revision: separated the now-observed exceptional migration from the recommended routine-update slice and retained earlier snapshots. Retain.

• RAILSPIKE.md effort checkpoints: distinguishes separately authorized operational work from automated feature completion and preserves the original baseline across rewritten history. Retain.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Step 4 implementation and stage-commit rules do not apply to this assessment revision.

Uncertain assessments

Current assessment plus preserved history exceeds the one-page Step 1 target. Keeping the current scope first aids review; historical snapshots remain intact rather than deleting study history. Future archival restructuring can shorten the active artifact without losing records.

2026-10-23T08:18:05+00:00 — Step 2

Necessary/useful instructions

• Step 2 Known environment: tied acceptance to the user's IntelliJ terminal over WSL clones and named concrete recovery actions. Retain.

• Step 2 Risks and shared component inventory: keeps rewrite detection a dependency of safe apply and prevents conflating checkout synchronization with the existing Railspike sync command. Retain.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Forum UI, database schema and documentation-only delivery rules do not apply to this operator-tooling scope.

Uncertain assessments

The one-page target competes with environment, recovery, component inventory and mandatory study metadata. Kept requirements grouped and avoided implementation design; detailed test staging remains for Step 3.

2026-10-23T09:50:06+00:00 — Step 3

Necessary/useful instructions

• Step 3 Key Risks and dependency ordering: requires history evidence tests before merge support, and stale-state checks before applying previews. Retain.

• Step 3 environment acceptance: dedicates closeout to replaying WSL terminal entry and recovery rather than claiming previous manual migration verified the new tool. Retain.

• Step 3 approval/commit gates: plan remains uncommitted and no implementation began. Retain.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Read-model schema and forum navigation checks do not apply to this operator command.

Uncertain assessments

The one-page target conflicts with seven stages each requiring six fields, material history/concurrency risks and study records. Preserved complete stage contracts over a literal page limit; stage sizing remains a review judgment, not measured effort.

2026-10-23T10:09:54+00:00 — Step 4 completed handoff

Necessary/useful instructions

• step4_implementation_do.md, Stage Boundary Protocol: separate commits retained verification evidence for registry, history evidence, preview, apply and recovery; final Stage 7 is 99be459f3. Retain stage summary/verification gates.

• step4_implementation_after.md, Contract and environment verification: real-Git wrapper acceptance plus an actual interrupted Git process and a WSL terminal transcript provided evidence beyond mocked command output. Retain the explicit limitation on actual IntelliJ UI verification.

• RAILSPIKE.md, effort checkpoints: preserved missing numeric projections and kept operational history migration separate from delivered automation; no accepted outcome invented. Retain.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Forum UI/theme/icon and read-model schema verification are inapplicable: changes add an operator CLI and tests, not browser navigation or schema.

Uncertain assessments

Stage 1's initial combined shell verification/commit call did not stop after a failed test; its JSON error-mode fix and successful rerun were committed separately as 3bd230353 before Stage 2. Summary preserves the failure rather than claiming the original check passed. Future stage calls should gate commits on tool success, as later stages did. This is execution discipline rather than evidence the workflow gate is unnecessary.

Final verification: scoped PHP harness 20/20, containing 32 real-Git cases; one additional actual interruption case passed separately. PHP/shell syntax, diff and cycle file links passed. Nine commits from planning through Stage 7 (minimum eight), with one additional Stage 1 correction. No full-suite, actual IntelliJ interaction, live enrollment, merge, push or history-erasure claim. Working tree clean after final log-only handoff commit. Maintainer fit/acceptance pending. Study snapshots remain canonical in Step 4 summary and indexed in the host ledger.
