0.69.0 (2026-09-16)

⚠ BREAKING CHANGES

db: SessionKanjiResult no longer accepts isCorrect, overridden, responseTime, or mcqCorrect, and sessionResult no longer has totalPoints/maxPossiblePoints columns. The DDL drop itself rides in Task 13's single hygiene migration, not this commit.

db: session-recording backfill — frame-echo tagging, D2 wipe, outcome backfill, activity heal
grader: captureDrawSample mutation + rejection wiring on all three draw surfaces
grader: draw duration + input type + rejection capture payload + grader_error telemetry
learn: frame echoes carry kind/frame_number/outcome + draw duration
review: recorder integration + responseTimeMs + scheduledDueAt threading
srs: session-recorder module — outcome model, first-resolution echoes
surfaces: completed pages + grid read the outcome model

Bug Fixes

db: guard outcome backfill against gap-window new-format rows
db: positive dimension discriminator for echo tagging + rating-accurate override comment
db: TZ-independent timestamp conversions + typed challenge results read
final-review seam fixes — tail-batch tagging guard, timestamptz completion, helper unification (spec v1.0.6)
grader: reset input-type capture per frame on the persistent Learn canvas
learn: first-attempt batch recording via session-recorder + stale storage clear
progress: tick study activity at three server write choke points
quiz: SET-not-ADD stage scoring + recorder payloads (accuracy can no longer exceed 100)
review: make the due contract type-visible through ReviewFrame
srs: late self-override upgrades the stored echo (spec §2 regardless-of-when)

⚠ BREAKING CHANGES

db: SessionKanjiResult no longer accepts isCorrect, overridden, responseTime, or mcqCorrect, and sessionResult no longer has totalPoints/maxPossiblePoints columns. The DDL drop itself rides in Task 13's single hygiene migration, not this commit.

grader: captureDrawSample mutation + rejection wiring on all three draw surfaces
grader: draw duration + input type + rejection capture payload + grader_error telemetry
learn: frame echoes carry kind/frame_number/outcome + draw duration
review: recorder integration + responseTimeMs + scheduledDueAt threading

db: guard outcome backfill against gap-window new-format rows
db: positive dimension discriminator for echo tagging + rating-accurate override comment
db: TZ-independent timestamp conversions + typed challenge results read

grader: reset input-type capture per frame on the persistent Learn canvas
learn: first-attempt batch recording via session-recorder + stale storage clear
progress: tick study activity at three server write choke points
