feat(linkedin-studio): RE-R2a — item→store capture bridge + publishedAt persistence (schema v1→v2, lossless migrate) [skip-docs]
Closes the research-engine capture loop RE-R1 deferred:
- itemToInput(item, capturedAt): pure envelope→TrendInput bridge in item.ts —
injects capturedAt, carries publishedAt verbatim; no id, no re-validate
- publishedAt persisted: TrendRecord/TrendInput gain it; addTrend conditional-spread,
first-sight kept on re-capture (no back-fill). SCHEMA_VERSION 1→2 with a lossless
forward migrate-on-load: Math.max(onDisk, current) + numeric-typeof coercion
(string/NaN/absent → current; non-array trends coercion preserved verbatim)
- `capture` CLI: stdin raw item|batch → normalize → bridge → addTrend → saveStore once;
tally {added,duplicates,merged,errors} from AddResult; content-invalid → errors[],
exit 2 only on bad stdin; --json summary
- wiring: trend-spotter.md Step 4.5 N×`add` → one normalizing `capture` batch; README
add/capture framing corrected; test-runner Section 16h (capture wiring, unconditional)
+ floors bumped (trends 62→79, ASSERT 87→90)
TDD: 17 new tests (12 genuinely-RED logic-RED + 5 regression guards), tsc clean,
gate 105/0/0. No version bump (additive, v0.5.2 dev).
