Adds --factstream HA soak mode driving real jstart/jfinish/jfail worker-fact
traffic against a live 3-node cluster, killing the primary mid-stream and
asserting zero committed-state divergence and zero phantom fact reactions.
Building this scenario surfaced bug-1416: persist_recover()'s boot-time
apply-correctness verification can race the live apply pump and the standby
live-replication apply path, both of which mutate the same last_applied_lsn/
job-table state the verification re-reads live -- producing a false
APPLY_DIVERGENT that permanently fences an otherwise-healthy node. Fixed with
a new persist_t.recovery_complete gate that defers only the in-memory apply
(never the durability write or replication ACK) while a recovery pass is in
flight, closed from the earliest safe point in myapp_run() so an election-
retry candidate can't apply live traffic before persist_recover() ever runs.
Round-2 adversarial review independently verified the ACK/durability paths
stay ungated, reproduced the myapp.c fix as load-bearing via revert-and-
reproduce, and confirmed real-divergence detection still fires. Live 3-node
factstream soak: 2/2 rounds PASS, zero APPLY_DIVERGENT across 5 recover
calls. controller_unit_test: zero new failures across 23 groups.
buglog.json had two broken auto-detection hook signatures polluting it:
- 207 entries "Missing error handling in X" / fix "Added try/catch block"
(nonsensical on .md/.capnp files, and C has no try/catch — never a real
applied fix)
- 452 entries with a literally-empty template ("Significant refactor of "
with no subject ever filled in) / fix "Rewrote N->M lines"
Removed both (659 total). Also merged 24 legitimate duplicate bug IDs
(re-logged/updated entries sharing an ID) into single entries — kept the
most recent content as primary, unioned tags/related_bugs, summed
occurrences — and stripped noise tags ('auto-detected', 'refactor') that
had leaked onto real entries from a since-merged junk duplicate. Net:
1406 -> 721 entries, verified zero remaining duplicate IDs and zero
remaining junk signatures.
.gitignore: added patterns for the scratch soak-run logs and codegraph.html
this session generated at repo root (already deleted from the tree), and
fixed the ucai-formatter-cache.local.json pattern to match its nested
occurrences (.claude/skills/*/.claude/, src/*/.claude/) instead of only the
repo-root one.

Green integration proof: 4 facts driven during total quorum loss append
RETAIN with rc 0 in <1000ms (vs 5000ms timeout — wrongly-applied WAIT
tripwire), pending with retained-depth=4 logged, present exactly once
on disk (real WAL header scan); reconnect + one covering ACK commits
the suffix with current_lsn unchanged (no redelivery). Completes the
bug-396 fix evidence (umbrella Req 2.8). Census 495/495.
4 green pins: handle_jobdispatch replies receipt-only with zero WAL
appends through a real 2-alloc dispatch cycle (notify outcomes intact,
reply-precedes-processing); set/clr_preason and do_update_op rusage
stay receipt-style with RETAIN-pending fact appends ACK-committed.
Umbrella Reply-Ordering Contract cited per pin. DISCOVERY bug-451
(reviewer-verified): RUSAGE hook va_list type confusion — 4-byte OOB
read + garbage state in WAL_JOB_RUSAGE payloads; fix deferred to 7.1.
Census 488; zero failures.
9 new cases (8-16): block-until-majority, deadline timeout, standalone
fast path, zero-ACK regression, n_vcpus-relative cap with floor, ACK
progress at saturation, gate as blocking predicate (NOT_READY is
admission-cap-only per corrected contract). Main-thread-only assertions
after joins; 16 tests / 9 RED failures; baseline unchanged.
Replace no-send stub with real WAL entry transmission via
xce_wal_batch_req_raw. For each non-catch-up registered standby,
serialize the entry header+payload into a wal_catchup_entry_t
and enqueue. Keep the MAX_PENDING_ACKS eviction guard.
5 new tests: no-standbys, one-standby-send, skip-catch-up,
evict-overloaded, send-failure-continues. Controller suite green.

Appended "Gap Analysis — Validation Pass (2026-06-09)" to each spec's
research.md with requirement-to-asset maps, status tags, and effort/risk.
Key outcomes:
- ha-repl-hardening: REOPENED with task series 7.1-7.7 — replication
payload data plane is missing (snapshot chunks and WAL catch-up ship
header-only; standbys converge on LSN without holding entity state)
- worker-join-refactor, resval-id-decoupling: marked implemented
(all criteria re-verified, full test suite green)
- buglog: 335/336 (scheduler dequeue, open), 337/338/339 (fixed in
previous commit); cerebrum Decision Log corrected (term-only vote
deny was recorded as intentional but was a regression)
