SESSION_GENERATOR_V1 — active implementation record

Date: 2026-09-10. Baseline: fd955315ccc9bb835a13eb94d206f1e01d893dfb (feat(training): complete training knowledge v1). Status: COMPLETED RECORD — SESSION_GENERATOR_V1=PASS. User authorization includes autonomous implementation, the approved additive Android migration, new V3 exchange, validation and all required reviews. No commit, push, staging, destructive Git or installed-app/data reset is allowed.

Settled gates — do not restart research

• ADVISOR_DECISION=PASS, including a bounded representation clarification: architecture decision.
• SESSION_GENERATOR_V1_SCIENTIFIC_REVIEW=PASS for the final policy delta: bounded scientific review.
• Canonical policy is frozen for implementation; domain semantics incorporates both decisions. The policy remains separately frozen and the full tranche has passed.
• Originating review is historical proposal evidence. Its 50%-MAX acceptance and numeric fallback tests are explicitly superseded. No MAX-derived numeric target or rounding is allowed.

Numeric load uses the newest qualifying same-exercise/exact-equipment external actual-dose occurrence within inclusive 28 days, with at least proposed count of positive finite actual weights at repetitions >= target. Use the minimum qualifying actual weight unchanged; otherwise absent. Legacy actual-only none/zero-rest/null-target history can qualify only with exact known compatible external equipment. It is not rewritten. Assistance and unknown context remain excluded. Generated absent-weight plans use planned mode none, independently of the equipment's resistance-context metadata.

Defaults, ranges, warning thresholds, scoring, coverage, and duration remain those of the retained scientific proposal. Count performed work only, grouped zones deduplicated with primary precedence, exact timestamp parsing, explicit malformed-time failure, no measured-recovery claim.

Architecture and implementation state

Desktop schema remains v11. Android v10 -> v11 adds the six planning columns only to completed/draft occurrences, with truthful none/0/NULL defaults. V3 session snapshots own targets atomically with ordinary occurrence data: trainlog-mobile-export-v3.json and trainlog-pc-mobile-export-v3.json. V1/V2 remain readable; V3 presence prevents fallback after failure. A legacy same-ID replay against nondefault local planning metadata conflicts explicitly. Preview is read-only. Accept creates the normal Android singleton draft only if absent; an existing draft conflicts without mutation. Desktop uses its normal in-memory session entry/editor/insertion path.

The persistence/V3 worker completed its bounded implementation and recorded /tmp/trainlog-session-generator-v1/persistence-v3-handoff.md: Kotlin SessionExercisePlan, schema migration, normal plan preservation, producer and consumer V3, transport precedence, truthful structural fixtures and shared cross-platform wire fixture. Initial validation passed 35 Android repository/ migration tests, assembleDebug, five affected Python suites, and sync_direction. This is an intermediate worker result, not an independent engineering PASS.

The C/Kotlin engines, strict policy derivation/loading, streaming history, owned bounded C inputs, full named scoring/coverage, dose edits, Android repository and editable preview, normal-draft acceptance and TUI flow are implemented. Independent validation passed Meson 45/45, focused ASan/UBSan 4/4, Android 73 tests with zero failures/errors and one external real-v9 fixture skip, public C17 headers, validators and deterministic regeneration. The new structural Android v10 migration test ran and passed without a skip. The bounded engineering delta review passed.

Exactly one deep final review ran and found three blocking gaps, retained in the final review. Its ONE bounded repair chain is complete. V3-only exact timestamp validation is repaired on both import/export implementations; focused tests prove rejection before mutation, supported grammar admission and malformed-present-V3 precedence over valid V2 through the actual Android inbox directory boundary. Handoff: /tmp/trainlog-session-generator-v1/v3-time-repair-handoff.md.

The worker session_generator_full_parity_repair now owns full normalized shared golden outputs and both C/Kotlin assertions, including score/coverage and identity/equipment anchor ties. Production policy and engines remain outside this test repair unless a demonstrated divergence requires repair. Current documentation includes the bounded active-V3/rest-zero correction. No separate generated-session history is authorized.

Completion record

Exactly one deep final audit initially found three repairable gaps. Its one authorized bounded repair chain closed V3 timestamp admission/publication, complete shared 16-case C/Kotlin parity, and current V3 documentation. The bounded repair review returned BOUNDED_FINAL_REPAIR_REVIEW=PASS; no second broad final review ran. The final matrix passed Meson 45/45, named ASan/UBSan 4/4, Android 75 with zero failures/errors and one unavailable external-v9 fixture skip, validators, strict headers, deterministic regeneration and APK asset comparisons. The structural Android v10 planning migration executed and passed. This record has no outstanding executable work; the parent may perform its final normal checks and evidence capture.

Protection and retained evidence

Ticket evidence root: /tmp/trainlog-session-generator-v1/. Original four proposals: original-proposal/ beneath that root. Baseline tracked hashes: baseline-tracked-hashes.json. Baseline real desktop read-only preservation: baseline-preservation.json. Desktop schema v11, integrity ok, no FK violations; 3 sessions, 31 occurrences, 28 performed sets, 19 MAX results, 6 continuous rows, 23 exercises, 3 custom equipment definitions, 32 exercise-zone rows, 23 zone-sync rows and 1 body observation. Compare the same logical-dump hashing method after implementation. No real user DB, installed Android application, keystore, sync history, Git index, commit or remote has been modified by this tranche.

The prior session's advisor thread-limit blocker was cleared in this session: advisor, bounded anatomy review and two implementation workers launched. There is no current infrastructure blocker. The exposed lifecycle interface has no close-agent tool; completed review agents were collected and interrupted using the only available lifecycle action. No role substitution was used.
