`task_sources::store::with_connection` re-ran the full schema DDL (2 `CREATE TABLE` + 1 `CREATE INDEX`) plus both `add_column_if_missing` migration probes on *every* call. Each probe prepares and runs `PRAGMA table_info(...)` and scans the table's columns, so this was pure fixed overhead ahead of the real query — and the periodic-poll fetch loop hits it three times per task (`is_ingested`, `get_card_id`, `mark_ingested`), on top of every other store op. Gate the DDL + migrations behind a per-path "already initialized" set so they run once per process per database file. This is the same accepted `flows::store` R-m8 gating and the companion `cron::store` change; the `task_sources` store was itself derived from `cron`'s `with_connection` idiom, so all three now share it. Every call still opens its own fresh `Connection` (`Connection` is `!Sync`); only the redundant schema work is elided. - `INITIALIZED_SCHEMAS: OnceLock<Mutex<HashSet<PathBuf>>>` keyed by db path (not a bare flag) so each test's per-`TempDir` workspace still initializes. - `ensure_schema_initialized` does a "trust, but verify" indexed `sqlite_master` lookup on a cache hit, so a database deleted or replaced at runtime self-heals instead of wedging at `no such table`. - The open-time pragmas are unchanged: `busy_timeout` and `journal_mode = WAL` stay in `with_connection`, and `foreign_keys = ON` moves *out* of the gated DDL into `with_connection` so it still runs on every open — the `ingested_tasks ON DELETE CASCADE` FK stays enforced. WAL is persistent in the db file but is kept with the other open-time pragmas to keep the connection setup byte-identical (idempotent per open). New `schema_reinitializes_when_the_database_file_is_deleted_at_runtime` test pins the verify-on-hit self-heal branch (WAL sidecars removed too).

Addresses the CodeRabbit (Major) and Codex (P2) review on tinyhumansai#5709. 1. Complete-schema validation. The cache-hit verify probed only for the `task_sources` table via `sqlite_master`, so a database replaced at runtime with an older/partial schema (that table present but missing `ingested_tasks` or a migrated column) was trusted and later failed on the incomplete schema. Replace the single-table probe with a `PRAGMA user_version` check: `init_schema` now stamps `TASK_SOURCES_SCHEMA_VERSION` after a full, successful migration, and a cache hit is honoured only when the on-disk version matches. Any deleted (fresh file => version 0) or drifted database re-runs the idempotent `init_schema`, restoring the pre-gating self-heal for column drift as well as a missing table. 2. Atomic per-path init. The `INITIALIZED_SCHEMAS` guard was released before `init_schema`, so two first callers for the same path could both run the DDL. Hold the guard across the verify + `init_schema` + insert so initialization happens exactly once per process per database file. On a cache hit the critical section is a single `PRAGMA user_version` read. New `older_on_disk_schema_under_a_cached_path_is_remigrated` test drops a migrated column and clears the version stamp under a cached path, then asserts the next store op re-migrates rather than failing `no such column`.

Mirrors the verified sibling change on tinyhumansai#5708. The process-global INITIALIZED_SCHEMAS mutex was held across the PRAGMA user_version read and init_schema, so every with_connection call took the lock on the hot path and independent db paths serialized during init. The on-disk user_version is already authoritative (init_schema stamps it only after a full migration), so read it lock-free first and return on a match — the common already-initialized case never touches the mutex. Only a version mismatch takes the lock, re-reads under it (double-check), and runs the DDL, so initialization stays atomic per path and migrated columns are still validated via the version gate (both earlier fixes preserved). INITIALIZED_SCHEMAS no longer gates the DDL; it is kept purely as a diagnostic marker so the "deleted/replaced at runtime" warning fires only for a path this process already initialized, not on every fresh-boot init (version 0). Both regression tests still pass (deletion self-heal + older-on-disk schema re-migration); 13/13 integrations::task_sources::store green.

This mirrors the exact change CodeRabbit verified on #5708 ("the original hot-path serialization finding is addressed; a path-specific lock registry is not required" — #5708 (comment)). Framing honestly: this is a code-clarity / correctness-of-locking change, not a measured speedup — the real win of the PR (DDL batch + metadata scans → one header read per call) is unchanged. |

🟡 Changes recommended
The new user_version check treats newer on-disk versions as a mismatch and can stamp the schema version downward, which is a correctness/compatibility bug on downgrade scenarios.

Pull request overview
This PR improves the Rust core’s task_sources SQLite store performance by avoiding repeated schema initialization work on every store operation, while preserving the “self-heal” behavior when the DB is deleted/replaced at runtime.
Changes:
- Added a per-db-path, process-wide schema initialization gate using
PRAGMA user_version, so DDL + additive migrations run only when needed. - Kept per-connection pragmas (
busy_timeout,journal_mode=WAL,foreign_keys=ON) applied on every connection open. - Added regression tests covering runtime DB deletion self-heal and “older schema swapped under cached path” re-migration.

Mirrors the verified sibling change on tinyhumansai#5708 (and tinyhumansai#5709). The process-global INITIALIZED_SCHEMAS mutex was held across the PRAGMA user_version read and init_schema, so every with_connection call took the lock — and in flows that runs once per node per live run via upsert_flow_run_step, not just at open, so the hot-path serialization is the most reachable of the three stores. The on-disk user_version is already authoritative (init_schema stamps it only after a full migration), so read it lock-free first and return on a match — the common already-initialized case never touches the mutex. Only a version mismatch takes the lock, re-reads under it (double-check), and runs the DDL, so initialization stays atomic per path and migrated columns are still validated via the version gate (both preserved). INITIALIZED_SCHEMAS no longer gates the DDL; it is kept purely as a diagnostic marker so the "deleted/replaced at runtime" warning fires only for a path this process already initialized, not on every fresh-boot init (version 0). All flows::store regression tests still pass (deletion self-heal, older-on-disk re-migration, per-path independence, fresh-init idempotence); 47/47 green. Claude-Session: https://claude.ai/code/session_01ACB4Ugi5pJMQqoCbZnVo6f
The is_current() check used == which treated a database created by a newer binary (on-disk user_version > expected) as needing re-initialization, unnecessarily re-running DDL and downgrading the version stamp. Fixes to >= TASK_SOURCES_SCHEMA_VERSION, matching the idiom in security/approval/store.rs, so a higher on-disk version is treated as already-initialized and left alone.

Summary
task_sources::store'swith_connectionre-ran the full schema DDL + both column migrations on every single query — the identical un-gated pattern PR perf(cron): run store schema DDL once per process, not per query #5708 proposed forcron::store, and the same idiom all three stores inherited from their sharedwith_connectionorigin.CREATE TABLE+ 1CREATE INDEX) and bothadd_column_if_missingprobes now run once per process per database file, gated behindPRAGMA user_version(on-disk schema authority) with a lock-free fast path. Every call still gets its own fresh connection.busy_timeout,journal_mode = WAL,foreign_keys = ON) are unchanged on every open; the self-healing on a deleted/replaced DB is preserved by a verify-on-hit and pinned by a new regression test.Review updates (post-open)
CodeRabbit (Major) and Codex (P2) reviewed the first commit; both are addressed in
44c19911c, and the design now supersedes the originalflows::storeprecedent rather than merely mirroring it (note:flows::storeno longer has per-op DDL gating in this repo — its schema init moved totinyflows-sqliteupstream;cron::store(#5708) is a sibling proposal, still open):init_schemastampsPRAGMA user_version = TASK_SOURCES_SCHEMA_VERSIONafter a full migration, and a hit is honoured only when the on-disk version is at least the expected version — so a runtime-replaced older/partial DB (missingingested_tasksor a migrated column likecard_id/assigned_executor) is re-migrated, not trusted then failed on the incomplete schema.684433d227): the comparison uses>=rather than==, treating a DB created by a newer binary (higheruser_version) as already-initialized rather than unnecessarily re-running DDL and downgrading the stamp. Matches the repo's idiom insecurity/approval/store.rs.INITIALIZED_SCHEMASguard is now held across the verify +init_schema+ insert, so two first callers for the same path can't both run the DDL. The fast path is lock-free — the mutex is taken only on a version mismatch, with a double-check under the lock.older_on_disk_schema_under_a_cached_path_is_remigratedtest pins the column-drift case (dropsassigned_executor, resetsuser_version, asserts re-migration).On the
flows::storeprecedent: the originalflows::storegating (single-tablesqlite_masterprobe + lock released beforeinit_schema) no longer exists onmain—flows::storewas reduced to a directory-substitution shim when the schema migrated totinyflows-sqliteupstream. Both gaps this PR fixed (complete-schema validation, atomic-per-path init) are therefore now resolved forflowsas part of that extraction rather than by an in-repo follow-up.Known tradeoff:
TASK_SOURCES_SCHEMA_VERSIONmust be bumped whenever a table/migration is added toinit_schema(documented on the const). A future migration added without bumping it would silently skip drift-detection for older DBs. The alternative — enumerating expected columns on each hit — carries the same discipline with more surface, souser_versionis the right call.Problem
Every store op funnels through
with_connection, and before this change each call paid, as pure fixed overhead before its one real query:Connection::open(kept — unavoidable,Connectionis!Sync),execute_batchof the DDL (2CREATE TABLE, 1CREATE INDEX),add_column_if_missingcalls, each preparing and runningPRAGMA table_info(...)and scanning the table's columns.None of it was gated. This is worse than a per-op tax: the periodic-poll fetch loop (
task_sources::pipeline) callsis_ingested,get_card_id, andmark_ingestedper task, so a fetch of N tasks paid the full DDL+migration setup 3N times — on top of every RPC-drivenlist_sources/get_source/add_source.Solution
Introduce per-process, per-path schema initialization gating via
PRAGMA user_version(the repo's established idiom, already used bysecurity/approval/store.rs):INITIALIZED_SCHEMAS: OnceLock<Mutex<HashSet<PathBuf>>>— keyed by db path (not a bare flag) so each test's per-TempDirworkspace still initializes. Used only as a diagnostic marker for runtime DB replacement detection; the on-disk version check is lock-free and the authority.init_schema(conn)— the DDL batch + the 2 migrations, split out ofwith_connection.ensure_schema_initialized(conn, db_path)— lock-free fast path returns immediately whenuser_version >= TASK_SOURCES_SCHEMA_VERSION; on a version mismatch it serializes init under the mutex with a double-check verify, runsinit_schema, stamps the version, and marks the path.Correctness — the connection setup is byte-identical. The three open-time pragmas still run on every open:
busy_timeoutandjournal_mode = WALstay inwith_connectionexactly as before, andforeign_keys = ONwas moved out of the gated DDL batch and intowith_connection(it is per-connection — not persisted in the db file — so it must run every open for theingested_tasks ON DELETE CASCADEFK to stay enforced).journal_mode = WALis persistent and could be gated too, but is left with the other open-time pragmas to keep the connection setup identical and the diff minimal; it is idempotent per open.Not extracting a shared helper across the three stores is intentional and matches the existing convention:
flows::store'sadd_column_if_missingdoc already states it is "kept per-domain rather than shared — each store owns its own connection helper and this is a handful of lines."Impact
integrationsfamily is always-compiled, no feature gate). No wire, schema, or config change; no migration.PRAGMA table_infoscans from every store op after the first per process, replaced by a single database-header read (PRAGMA user_version) — most impactful inside the per-task fetch loop, which paid it 3× per task. "Remove redundant repeated work on a recurring path," not a hot-loop micro-opt.Submission Checklist
schema_reinitializes_when_the_database_file_is_deleted_at_runtimeregression pins the verify-on-hit self-heal branch (the one path the gate could regress; WAL sidecars removed too);older_on_disk_schema_under_a_cached_path_is_remigratedpins the column-drift re-migration case.

cron::storefix is perf(cron): run store schema DDL once per process, not per query #5708 (same pattern). This PR is the deferred follow-up noted there; it touches onlytask_sources/store.rsand does not overlap my open fix(task-sources): don't prune board cards on a truncated (full-page) fetch #5521 (which istask_sources/pipeline.rs).AI Authored PR Metadata (required for Codex/Linear PRs)
