Garry TanandClaude Opus 4.7 9e17d0076a feat(schema): migration v93 take_domain_assignments (v0.41 T1)
Adds the JOIN table backing per-pack calibration domain aggregation
in the v0.41 lens-packs wave. Replaces the originally-planned scalar
`takes.domain` column after codex outside-voice review caught that
one take can legitimately belong to multiple domains (a take about
"Sequoia's investment in Anthropic" lands in deal_success AND
market_call), and that scalar attribution bakes today's pack→domain
mapping into permanent fact.

Schema: composite PK (take_id, domain) for idempotent re-assignment,
FK CASCADE so deleting a take cascades assignments, confidence CHECK
in [0,1], idx_take_domain_assignments_domain for the aggregator JOIN
direction. RLS guard matches takes/synthesis_evidence pattern (enable
when running as BYPASSRLS role). PGLite parity via sqlFor.pglite.

Backward-compat: pre-existing takes carry no assignments; aggregator
LEFT JOIN skips them gracefully. No backfill required at migration
time — propose_takes (T10) populates new rows; greenfield assignment
of historical takes is a v0.42 follow-up.

R-MIG IRON-RULE regression at test/migrations-v93.test.ts pins 12
contracts: existence/name, LATEST_VERSION advance, table queryable
after initSchema, column shape, composite PK rejects duplicate
(take_id, domain), multi-domain assignment permitted, FK ON DELETE
CASCADE, CHECK rejects out-of-range confidence, index presence,
aggregator JOIN direction returns per-domain counts, sql/sqlFor.pglite
parity grep, backward-compat LEFT JOIN handles unassigned takes.

Plan: ~/.claude/plans/system-instruction-you-are-working-toasty-milner.md
First of 13 sequencing tasks in v0.41 lens packs + epistemology
unification wave (decisions D9-B → T1-B per codex challenge).
