Private-message idle synchronization — debug log

2026-10-29 UTC — Step 1

Necessary/useful instructions

• Source: step1_solution_assessment.md, Original Query and Understood Intent. Contribution: retained the user's one-check clarification and unused-account gate together; avoided interpreting the first question as requiring a single round trip for cryptographic recovery. Suggestion: retain.

• Source: docs/concepts.md, Planning. Contribution: separates a derived history-eligibility gate from membership or browser-local usage and keeps missing inventory entries proposed until implementation. Suggestion: retain.

• Source: RAILSPIKE.md, effort intake/exposure. Contribution: records source exposure from the preceding conversation rather than claiming an uninformed initial estimate. Suggestion: retain.

Redundant/unnecessary instructions

• No supported findings.

Uncertain assessments

• Source: Step 1 Deliverable one-page target alongside required study/concept fields. Observation: required metadata expands this assessment beyond a conventional printed page despite two concise options. Suggestion: clarify whether metadata is excluded from the target.

Verification: Compared the client batch/acknowledgment loop, account/sender work service, sync store, unread service and existing sender privacy requirements. Confirmed no relevant concept inventory entry exists and verified frozen R1 hashes. No runtime, production or implementation checks claimed. Planning remains uncommitted; Step 2 requires approval.

2026-10-29T20:17:46Z — Step 2

Necessary/useful instructions

• Source: step2_feature_description.md, Known user or environment. Contribution: production network acceptance is distinguished from local browser evidence, with ordinary entry and unaided retry specified. Suggestion: retain.

• Source: step2_feature_description.md, Risks and shared component inventory. Contribution: makes false-idle starvation and sender privacy constraints explicit and reuses existing unread/retry surfaces. Suggestion: retain.

Redundant/unnecessary instructions

• No supported findings.

Uncertain assessments

• Source: step2_feature_description.md, one-page deliverable. Required recovery, surface inventory, concepts and study metadata exceed a conventional printed page; retained concise sections to preserve reviewable requirements. Suggestion: distinguish narrative target from required metadata.

Verification: Restored approved Option A and debug/study state, inspected the actual shared unread coordinator, reverified three frozen R1 source hashes and checked document whitespace. No runtime or production checks claimed. Step 2 only; no application changes or commits.

2026-10-29 UTC — Step 3

Necessary/useful instructions

• Source: step3_development_plan_do.md, Key Risks and dependent work. Contribution: donor privacy and invalid-contribution recovery are verified before suppression and combined browser integration. Suggestion: retain.

• Source: step3_development_plan_after.md, known environment evidence. Contribution: production replay stays explicit and pending until authorized deployment rather than being inferred from local tests. Suggestion: retain.

Redundant/unnecessary instructions

• No supported findings.

Uncertain assessments

• Source: Step 3 one-page target and mandatory per-stage fields. Six small stages with risk, estimate and verification fields exceed one printed page. Suggestion: treat compact reviewability as the target when mandatory metadata exceeds a page.

Verification: User-requested origin/main fast-forward to e614fbd9b completed; append-only ledger conflict resolved retaining upstream and cycle entries. Inspected existing work/cursor, sender contribution and browser scheduling contracts; planning document whitespace and conflict-marker checks performed. No runtime tests or application edits. Debug and extended estimates remain enabled. Approval required before implementation.

2026-10-29 UTC — Step 4 completed

Necessary/useful instructions

• Source: step4_implementation_do.md, Stage Boundary Protocol. Contribution: preserved separate eligibility, donor evidence, combined discovery, browser, acceptance and documentation commits with contemporaneous evidence. Suggestion: retain.

• Source: step4_implementation_after.md, evidence boundaries. Contribution: the broader conversation-list failure was reproduced against untouched main instead of being labeled a new defect or silently counted as passing; production replay stays pending. Suggestion: retain.

• Source: docs/concepts.md, Implementation and verification. Contribution: records history eligibility as derived scheduling state and distinguishes supplied donor access from verified recipient readability. Suggestion: retain.

Redundant/unnecessary instructions

• No supported findings.

Uncertain assessments

• Source: step3_development_plan_do.md, roughly 50 lines per stage. Integration tests and recovery evidence exceed the line heuristic while each stage retains a bounded coherent outcome. Suggestion: treat changed-line count as a warning rather than an acceptance criterion.

Verification: Seven required commits present, including planning before summary and one per six stages; closeout commit 5ef9a1b35. Focused and browser results/omissions recorded in summary. Scoped documentation links and whitespace verified; no dependency/schema delta, merge, push or deployment. Debug mode remains enabled. This report is the separate log-only handoff commit required after the final stage.
