Make the hash-floor gate deterministic (V-718)

Owner explicitly requested direct commits to master. Keep startup cost benchmarked without turning ambient race/coverage load into a correctness failure; record live reminder proof, stale-task reconciliation, and the temporary delegation quota caveat.

+## 2026-08-15 — authoritative-state continuation
+
+The continuation began by treating the checked-out tree and external task state
+as authoritative. `master` was clean, identical to `origin/master`, and already
+contained the V-717 and V-687 branch merges. Their interrupted worker messages
+were therefore not used as evidence of missing work.
+
+### Live reminder catch-up closes V-570 and V-715
+
+The rebuilt stack loaded the resident Qwen model, multilingual ONNX embedder,
+and routing heads. On its first eligible tick it phrased the three overdue
+reminders once as one catch-up message. Disabled ntfy left one durable failed
+attempt for delivery group `reminder #83`; ordered fallback then left exactly
+one successful Telegram attempt for the same group. All originals became
+`fired`. Four later ticks produced no second phrase, send, pending attempt, or
+unknown attempt. `/`, `/reminders`, and `/notifications` each returned HTTP 200
+with a server-generated request ID. This supplies the live evidence that was
+still missing in the 2026-08-13 entry; V-715 and the stale-open V-570 are closed.
+
+The first HTTP repro command also exposed a zsh test-harness trap: `path` is a
+special array tied to `PATH`, so using it as a loop variable removed command
+lookup inside the loop. The corrected probe used `probe_path` and `wget
+--no-proxy`; the deployed web process had not crashed.
+
+### Stale-open task reconciliation
+
+The open Vikunja list was read with `done: false` and compared with the current
+tree before choosing work. V-397 already described itself as done and merged;
+V-557 is present as `ea0eb16` plus the forced missing-slot dialogue contract;
+V-570 is covered by the live catch-up proof above. Those three records were
+closed rather than reimplemented. V-651 remains open: its nil-sink and reminder
+spin halves landed with V-715, but the first failed severity-4 Telegram send is
+still not represented in the repeat-until-ack stream.
+
+### Stable hash-floor performance evidence [V-718]
+
+`TestPersonalBoundaryHashFloorLatency` coupled correctness to ambient machine
+load while running a numeric training loop under race and coverage
+instrumentation. It is now a deterministic fit-and-score test that also proves
+the 1024-dimensional head was built. Elapsed time remains observable through
+`BenchmarkPersonalBoundaryHashFloorFitAndScore`, where three one-iteration runs
+on this host measured 75.1 ms, 76.8 ms and 81.4 ms without making those host
+figures a CI pass condition.
+
+The exact race-plus-coverage focused test passed in 9.445s. `make test` then
+passed on its first run: formatting, vet, CW2 configuration tests, and every
+internal and command package under race plus coverage; `cmd/mavend` completed
+in 205.712s. This closes V-718 without raising a brittle timeout.
+
+### Delegation availability
+
+All three available subagent slots were filled: clarification exhaustion,
+durable nudge identity, and a read-only live deployment probe. The first two
+left complete merges on `master`; all three later reported the same shared
+Codex usage limit, with capacity unavailable until 2026-08-20. Work continues
+serially. The temporary constraint and revisit trigger are recorded at
+`docs/caveats/workers.md#agent-quota` under the V-714 completion umbrella.
