Thread-like Activity — Railspike debug log

2026-10-23 — Step 1 handoff

Necessary/useful instructions

• docs/railspike/docs/workflow/step1_solution_assessment.md, Options and vertical-slice recommendation: compares per-contribution activity, a summary feed and the existing commit workaround, while retaining the user's ordinary Like-to-Activity outcome. Retain the comparison requirement.

• Same file, Original Query/Understood Intent: preserves the user's cancellation of committing remaining files and explicitly names the diagnosed thread/action. Retain the distinction between the request and contextual interpretation.

• docs/railspike/RAILSPIKE.md, Experimental Effort Estimation: discloses pre-intake diagnostic exposure and missing frozen sources instead of inventing a numeric rating. Retain reference identity and checkpoint history requirements.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• Step 4 branch/commit gates do not apply: these drafts remain uncommitted on the existing branch. Approval of the prior cleanup implementation does not approve this new cycle.

Uncertain assessments

• Distinct-action identity versus recovery/replay deduplication needs Step 2 inspection; the assessment requires preserving current write eligibility rather than silently broadening vote permissions.

• Frozen R1 report/diff remain unavailable. Numeric projections are unavailable, not zero; no new reference set is introduced.

2026-10-23 — Step 2 handoff

Necessary/useful instructions

• docs/railspike/docs/workflow/step2_feature_description.md, Known user or environment: names the exact local later-like failure and requires an isolated reproduction plus read-only confirmation, not mutation of the user's content during tests. Retain the normal-entry and recovery requirement.

• Same file, Shared component inventory and Enhancement Requests: keeps classic/Forte/feed consumers aligned and separates the broader repository checklist, unlike controls and duplicate-guard bug from the approved likes-reporting slice. Retain explicit scope boundaries.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• Step 3 and implementation/commit rules remain pending Step 2 approval. No application edits, test execution or new branch are authorized at this handoff.

Uncertain assessments

• Historical source-commit attribution differs between the current incremental and rebuild paths; Step 3 must resolve that within the existing evidence contract rather than assigning older likes to the newest write.

• Numeric projection remains unavailable pending exact frozen R1 recovery; prior checkpoint limitations remain intact.

2026-10-23 — Step 3 handoff

Necessary/useful instructions

• docs/railspike/docs/workflow/step3_development_plan_do.md, Completion Contract and known-environment acceptance: the final stage must replay the reported local two-like case in isolation and verify actual Like-to-Activity discovery; normal startup must repair existing derived state. Retain these requirements.

• Same file, stage dependencies and material risks: historical commit attribution is resolved before browser/startup closeout, and Activity identity is separated from scoring deduplication. Retain explicit evidence/parity gates.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• Step 4 branching and organization remain pending Approved Step 3. No application changes, commits or new tests were made for this planning handoff.

Uncertain assessments

• Four one-hour stage targets are planning bounds, not measured work or an independent numeric estimate; discoveries require revision before dependent implementation.

• Frozen R1 sources remain missing, so the numeric total remains unavailable rather than assigning a replacement reference or reconstructing past estimates.

2026-10-23 UTC — Step 4 completed handoff

Necessary/useful instructions

• docs/railspike/docs/workflow/step4_implementation_before.md and step4_implementation_do.md, planning organization/commit gate and stage commit cadence: planning ab24d158 contains only Steps 1–3, existing debug history and index organization; the summary begins in Stage 1. Stages 540777f2, 375fed9e, 3ef2401c, a7b79a45 each include their summary update. Final review confirmed the minimum planning-plus-stage count and no unrelated drafts in commits. Retain these reviewable boundaries.

• step4_implementation_do.md, Completion Contract/known-environment acceptance: an isolated copy of the exact local repository proved baseline one-event versus corrected two-event recovery, unchanged scoring and original-record hash. Signed-button browser tests separately verified actual normal entry, source bytes/signature, classic/Forte Activity and RSS rather than relying only on SQL. Retain the distinction between fixture checks and user-condition evidence.

• step4_implementation_after.md, verification/omission reporting: focused PHP checks (29 tests plus the extended missing-history regression), real-browser phone/desktop/theme/empty/retry coverage, syntax, links and commit gates are recorded separately from unverified live deployment, physical devices and full-suite verification. PHP GD remains absent; preceding-cycle baseline image failures were not misreported as a current full-suite run. Retain explicit evidence boundaries.

• docs/railspike/RAILSPIKE.md, Experimental Effort Estimation/checkpoints: entry reaffirmed unavailable numeric projection; closeout separately records retrospective scope and pending maintainer fit. R1/P2, exposed rater and missing earlier checkpoints remain unchanged. Only this cycle's ledger section was staged; unrelated unpin planning stays in the working copy. Retain stable identity and scoped ledger rules.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• New navigation/icon and UI copy-cleanup requirements: no controls, navigation destinations or product copy changed. Shared Activity rendering was still verified because row derivation changed.

• Production deployment, physical-device acceptance and new authorization roles are outside the approved local implementation; no original canonical records or live read model were changed as a test fixture.

• Independent/sub-agent study ratings: no delegation requested or performed; a single exposed rater is recorded.

Uncertain assessments

• Frozen R1 calibration sources remain unavailable; numeric projected/retrospective scores cannot be recovered from stage count, elapsed time or patch size. Maintainer fit and acceptance remain pending.

• Rapid repeated navigation of one browser page intermittently aborted theme matrix navigation. Fresh pages per matrix case, actual viewport/theme assertions and full page loads resolved the harness instability; final complete signed-browser and shared-reader runs passed. This was not counted as an application regression or evidence of deployment behavior.

Final review and handoff state

Planning and four summary-bearing stage commits verified, with documentation-only clarification 6bf1b5c5 accurately distinguishing Stage 1 normal writes from Stage 4 signed-browser coverage. Feature link/path checks and whitespace checks passed. Debug mode restored as enabled from the summary; this separate commit contains only the completed-step report. Original unrelated unpin ledger draft, repository-coverage backlog, .test_self_approval and concurrent todo.txt change are preserved outside the cycle's commits. Branch is feat/thread-like-activity; merge/deployment not performed. Prior branch-push preference is carried forward to origin publication of this reviewable branch.
