glm-5.3-flash c3a0c54df0 tests: review 003 Findings 2-3 — pre-release dispositions ...

Finding 2(a) landed: a one-shot cfg(test) generation-top LISTEN-pause
seam on the pg forwarder (listen_pause in seam.rs) lets the LISTEN-window
death test kill the fresh reconnect generation's backend before its
snapshot LISTEN — the LISTEN then fails honestly (57P01 terminating) and
the production fall-through arm (listen_ok == false) runs unmodified.
The harness test pins the honest mid-reconnect transient, full recovery
(wake, re-issue recovery of the refused mid-gap registration), and the
exactly-one-wake differentiator; a server-less unit pin covers the flag.
Finding 2(b) + the defensive arms stay parked with the code-read as pin,
recorded in the task file with current line refs.

Finding 3 landed: the rollback_fault seam (commit-fault mechanics) feeds
SQLITE_FULL-shaped errors into both ROLLBACK failure drop paths —
SqliteTxHandle::drop and the cancelled op's ConnLease::drop — exercised
in one test (phases: open-handle drop; single-poll-then-drop mid-op
cancellation), pinning slot replenish via reopen, no ghosts, and the
store staying usable.

Contract-suite rows (task suite-opts-backoff-rows): the backoff-curve equivalence row and the deferred enqueue-opts clock legs. backoff_curve_equivalence — the equal-jitter exponential pinned as the range, not a jitter label (ADR-010 §3): claim → retry(err, None) cycles on a backoff_base_s = 2 queue land the ranges [1,2], [2,4], [4,8] across attempts 1–3, each computed delay read back through get_job's resolved run_at minus a clock read taken before the retry — the lower bound race-free (the retry's internal clock read cannot precede the suite's, so the observed value over-reads the delay, never under-reads) and the upper bound carrying a one-second straddle tolerance for the integer-second stamp crossing a wall second; identical bounds on both engines is the equivalence pin (ADR-012 §2, the row body shared). The explicit-delay override legs ride the same row: retry(err, Some(5)) honored verbatim ([5, 6] under the same straddle tolerance) and retry(err, Some(0)) resolving ready-now per the boundary-total rule (ADR-023 §2), claimed within a bounded wait. enqueue_opts_resolution extended in place with the wave-5 legs its deferral note named — the run_at-alone literal leg (a future run_at is the row's ready time verbatim, a deterministic equality with no clock read involved; a past run_at stores the literal too and is claimable now through the run_at <= now predicate within a bounded wait, the run_at-ASC ordering making the observation unambiguous among the row's other legs) and the neither-field leg (ready at the enqueue instant, abs_diff(now) <= 5 tolerance-bounded proximity, never a tight timing assert); the deferral note replaced by the completion statement, ADR-023 §2 stamp accumulated per the convention (ADR-020 §1 governs the resolutions). Cap-leg disposition recorded in Notes for the review gate: the 1-hour cap is not suite-pinnable (capped attempts need minute-scale waits) and stays pinned engine-side on both engines' unit tests per the wave-3/4 reviews. Ready-now waits are bounded claim_one poll loops (deadline asserts only, sequential single-store drive), with the one draft defect the finding surfaced (a re-claim after the bounded wait consumed nothing; the helper returns the claimed handle) noted. Wired into both engines' suite targets (SQLite tokio test, pg harness_row!), 25 rows per column up from 24. Verified: SQLite column green server-less (25/25 suite, 189 lib), pg column green vs harness (postgres/poc@:15432 — 25/25 suite, 121 lib + 9 schema), 3 solo re-runs of each new/extended row per engine (determinism), server-less pg skips cleanly via the reachability gate, cargo test -p alkstore-sqlite -p alkstore-postgres green, clippy -D warnings, fmt clean
