feat(tests): the conformance suite's fleet column — the exact-count fleet sweep outcomes under concurrency, green against the harness server (wave 6)
- tests/conformance/fleet_column.rs (cfg feature = "postgres"; the consolidation pieces cfg the postgres+pg-lo pair): the fleet-validity rows, the joint entry+pin tx rows (both-or-neither over an independent connection; the dedup re-put's upsert-renew; the second instance's re-put composing a second row — protection by row; the pg-lo consolidation round-trip byte-exact over the shared instance), the TTL/renewal rows (the guard's TTL/3 cadence through the short test TTL; the never-resurrect semantics through the facade; the paused holder's expiry boundary with the delete-then-recover backstop), and the exact-count fleet sweep rows — the wave's gate, INV-4's engine-gated fleet form: the two-instance exact-count shape, the lease contention row (SweeperLock as report data, nothing deleted), the cross-instance arbitration row (GcRefuse until the foreign row's expiry), the race across the window delay closed by the row, the maintenance step's exact reap, and the fleet liveness verb row (the schema-ownership rule asserted; the deregistration correction flow); the kv-only rejection row mirrored verbatim against the fleet kv-only factory - three fleet factories after the postgres column's registry pattern extended to the fleet shape — one minted schema, two Store instances over it, each its own owner id (the pin rows compose by owner); the dual-tier instances carry private local roots riding FleetSharedMedia::asserted; the consolidation factory follows the pg-lo column's LO-isolation corollary (a TrackedDb::new constructor added to pg_lo_column.rs for the private janitor field); teardown drops exactly the minted schemas — idempotent, owned, panicking-row-safe, structurally exercised - the SKIP posture rides the postgres column's reachability probe: server-less runs skip cleanly, acceptance is green against pglo-poc (:15432) under --features postgres with the consolidation rows under --all-features; the test tuning is the window delay 0 and the short test pin TTL (the fleet constructors' parameter) — ordering rides the tunings or the manual-expiry instrument, no sleep-based race assertions - README amended: the fleet rows table (§Columns beyond the reference set), §Column plan (the fleet column is the wave-6 gate's host), §Current state — six columns - task suite-column-fleet completed (Notes + Summary recorded, including the recorded deviations: the structural predicate shapes reach no fleet constructor; the cross-instance mismatch leg is unexercisable on the one-instance harness server — the probe's errors-closed posture asserted instead) Verification: cargo test (default) green; cargo test --features postgres green server-less (skipping) and green against the harness server; cargo test --all-features green against the server (125 conformance + 226 library tests); cargo clippy --all-targets -- -D warnings and cargo fmt --check green on the default, postgres, and all-features variants |

docs(tasks): decompose wave 6 — the fleet GC mechanism, the architecture's most intricate state machine under concurrency
- store-fleet-construction: the fleet: true declaration slotting into the fleet-capable constructors (the recorded non-event), the composite fleet-validity predicate enforced at the constructor (kv=postgres AND pg-lo-same-instance OR local-on-declared-shared- media OR kv-only re-routing), the TTL/owner-id fleet state, the same-instance probe design point - engine-pg-lo-joint: the pg-lo joint contribution — staged-put mechanics (512 KiB knee, CAS, transactional LO creation) into the store-held PgJointTx, the wave-5 deferred API-shape design point - store-fleet-put: the joint entry+pin tx driver (amendment A1's drop discipline lands here — its recorded owner), the pin guard's TTL/3 renewal form, the dedup upsert-renewal, pin-first/ publish-second for large=local, the consolidation one-tx put - store-fleet-sweep: the SQL sweep lease (ADR-013 §2 semantics), SQL-level delete arbitration on the direct + window-execution paths, the expired-pin reaping clause (the seam as the named home for fleet-clause growth), the fleet liveness registration verb, the two-domain arbitration composition - suite-column-fleet: the fleet column — two-instance factories over one schema, the exact-count fleet sweep rows (the wave's gate), lease contention, cross-instance arbitration, TTL/renewal rows, the fleet-validity predicate rows - review-wave-6: the fleet gate per the plan, plus a standing code-smell/hygiene block — cargo doc --no-deps asserted clean (the twice-bitten PGLO-1 rustdoc private-link class), the allow(dead_code) scope notes audited against their remainder, stale wave-6 forward references, and task-Summary-vs-diff correctness Harness server cited in every server-touching task: dockerized pglo-poc (postgres:16-alpine) on :15432, db blobs, postgres/poc (verified live 2026-10-12); env-driven ALKBLOBS_PG_* settings, clean server-less skips, acceptance requires green against the server. Dependency graph validated: two parallel roots (construction, pg-lo joint), put merging them, sweep parallel to put, the fleet column merging, the review gate last; no cycles. |
