# 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_architecture_review.md).
- `SESSION_GENERATOR_V1_SCIENTIFIC_REVIEW=PASS` for the final policy delta:
[bounded scientific review](session_generator_v1_scientific_delta_review.md).
- [Canonical policy](../../catalog/session-generation-policy-v1.json) is frozen
for implementation; [domain semantics](../domain/session_generation.md)
incorporates both decisions. The policy remains separately frozen and the
full tranche has passed.
- [Originating review](session_generator_v1_scientific_review.md) 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explicitly superseded.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](session_generator_v1_final_review.md). 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.
