Absent retraction snapshot debug log

2026-10-23T18:16:27Z Step 1

Debug enabled by the project marker; implementation unapproved.

Necessary/useful instructions

• docs/workflow/step1_solution_assessment.md, Structure and Guardrails: comparing approaches separated safe handling of absent targets from historical repair and partial publication. Retain the comparison and approval gate.

• RAILSPIKE.md, Experimental Effort Estimation: prior inspection exposure and unavailable frozen references are explicit, avoiding an invented prospective estimate. Retain these constraints.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• RAILSPIKE.md, Planning Artifacts: branch creation, plan moves and stage commits await Step 3 approval. Preserve the gate; current planning files stay uncommitted.

Uncertain assessments

• Frozen R1 report/diff sources are absent at the recorded location. Numeric projection remains unavailable; no substitute reference was introduced.

2026-10-23 Step 1 revision for snapshot publication

Necessary/useful instructions

• Step 1 review and revision preserves the original query while recording the user's correction separately. Scope v2 and renamed artifact references now address offline snapshot publication.

• Study continuity preserves the original cycle ID and scope v1 history despite the filename change.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• The usual uncommitted Steps 1–3 rule is overridden for this documentation handoff by the user's explicit request to commit for later work on dev. This is not step approval or implementation authorization.

2026-10-23T19:20:50Z Step 1 scoring revision

Necessary/useful instructions

• RAILSPIKE.md, Experimental Effort Estimation: restoring host-ledger state revealed exact recovered R1 snapshots; matching all hashes enables new ratings while preserving historical unavailable checkpoints. Retain reference verification and dated revision rules.

• Step 1 Review and revision: option scoring stays within the current assessment; it does not authorize Step 2. Retain the approval boundary.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• Step 4 branch and stage-commit requirements remain inapplicable to this assessment revision.

Uncertain assessments

• Scores are exposed single-rater scope judgments based on existing assessment evidence; detailed planning may revise them. No new runtime verification was performed.

2026-10-23T19:25:12Z Step 1 scope v3 revision

Necessary/useful instructions

• Step 1 Review and revision and RAILSPIKE.md, Enhancement Requests: recorded the rejection of abort-on-reappearance and updated the current option without advancing to Step 2. Retain scope/approval separation.

• Experimental Effort Estimation: retained v2 0.85 separately from provisional v3 0.70 and preserved the stable cycle ID. Retain revision history and verification-inclusive scoring.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• Step 4 implementation and commit cadence do not apply to this unapproved assessment revision.

Uncertain assessments

• Same-build exclusion may require more coordination than anticipated, especially for update snapshots retaining older base content. Detailed planning must validate the provisional scope reduction; runtime behavior has not been verified.

2026-10-23T19:37:36Z Step 2 handoff

Necessary/useful instructions

• Step 2 Completion boundary and Shared component inventory: linked direct/queued entry to actual offline base/update consumption and existing shared publication consumers. Retain these requirements to prevent guard-only acceptance.

• Step 2 Risks: surfaced earlier-base leakage before implementation planning; retain early validation gates.

• Experimental Effort Estimation: reaffirmed v3 0.70 without overwriting earlier unavailable or v2 scores. Retain checkpoint continuity.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• Documentation-only delivery restrictions do not apply to this application-change scope; no implementation is authorized yet.

Uncertain assessments

• Build-local exclusion and earlier-base removal have not been implemented or exercised. Step 3 must validate feasibility before dependent stages; 0.70 remains provisional.

2026-10-23T19:43:15Z Step 3 handoff

Necessary/useful instructions

• Step 3 Key Risks and Completion Contract: inspection exposed thread-bounded update replacement, making explicit stale-base exclusion necessary. Retain normal-consumer acceptance and early risk gates.

• Before/Do/After phase sequence and approval boundary: planning was completed without application edits, branching or commits. Retain implementation gate.

• Effort checkpoint rules preserve scope v3 and earlier 0.85/0.70 records separately.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• Documentation-only boundary is inapplicable; this is application work. Production deployment/live retries remain excluded.

Uncertain assessments

• Static inspection establishes the update gap, not runtime feasibility. Stage 1 validation and Stage 3 consumption checks must resolve safety before dependents; stage sizing/0.70 remains an exposed estimate.

2026-10-23T20:17:54Z Step 4 completed handoff

Debug mode: enabled, inherited from approved Step 3. Planning fd4fa3839; stages 622adaf59, 5c7b6a3a0, 63ef804bf, 6012d8a65, 6aff8c726. Branch feat/absent-retraction-snapshot; no merge/push/deployment/live repair/task retry. Scope v3, stable study ID/R1/P2 and exposed single rater preserved; 0.70 projection and separate 0.80 retrospective assessment recorded in summary/ledger, maintainer acceptance pending.

Necessary/useful instructions

• step4_implementation_before.md, Planning Docs Commit Gate: plans were organized with repaired navigation/index, committed before the summary or runtime changes; preserved a reviewable approved boundary. Retain the gate.

• step4_implementation_do.md, Stage Boundary Protocol: each of five stages has scoped verification and a summary-bearing commit before the next stage. Retain traceability; final correction to rootless post Likes is covered by real browser assertions.

• step4_implementation_after.md, Final Verification Checklist: full-suite results are explicitly incomplete (75 passes before interruption) rather than inferred from 57 focused cases/16 browser scenarios. Final reader correction was verified separately after the frozen full-suite copy was created. Retain this distinction.

• RAILSPIKE.md, Experimental Effort Estimation: preserves historical unavailable checkpoints and scope v2 0.85/v3 0.70 separately; final 0.80 is retrospective and not measured labor or acceptance. Retain score semantics.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• Documentation-only scope and core read-model migration checks are inapplicable: this is an application change to portable snapshot metadata and PHP-side filtering with unchanged core queries/schema. Deployment, physical-device and installed-client upgrade verification are outside local implementation acceptance. No navigation destination/icon changes occurred.

Uncertain assessments

• Changing host documentation during a full static-publication regression triggered its intentional fingerprint guard. A frozen bounded-doc fixture then passed both shared import/static recovery tests; an immutable full-tree attempt passed 75 cases, including full-corpus legacy bootstrap, before deliberate interruption in a long import test. These results do not establish full-suite success or a baseline failure. Consider documenting an immutable-copy test setup before workflows with concurrent plan edits and guarded document publication.

• Installed service-worker upgrades and production deployment remain unverified; portable version-5 exclusions require updated reader assets. Required local CLI/configured-worker, source safety/reappearance, stale-base/dependent-expansion and rendered-reader recovery were verified. No claim of maintainer comfortable-fit acceptance is made.
