Sibling of D209 (A1 raw-byte union-alias class). chrToPatrol writes
act_init.padding[0x13] (union byte 0x4c) = -1, which is act_patrol.lastvisible60
on N64. act_patrol starts with a patrol_path* that widens 4->8 on x86-64, so
0x4c now lands in waydata and lastvisible60 (@0x50) stays uninitialised. The
patrol 'haven't seen the player recently' gate (chraction.c:~9347) then reads
garbage on the first ticks after entering PATROL.
Fix: write the named field under #ifdef PORT; N64 line verbatim under #else.
ABI/pointer-width only, no game-logic change.
Found by the post-D209 A1 sweep; the only new instance (act_anim/act_dead
padding aliases are pointer-free -> layout-stable).
Build clean; bunker1 + facility verify PASS (both patrol-heavy), no crash.
findings D210 + porting-notes A1 + findings-index regen.
Root cause of the "doesn't recover after the alarm stops" half of the user's
D207 report (distinct bug from D207's voice-pool question).
struct field bondview.h:200 `s32 field_A48` is used as a SECOND
ALSoundState* sound-handle slot for the player's double-buffered per-hand
fire sound (gunfire.c:3186-3200). sndPlaySfx stores the new state through
`&field_A48` as an 8-byte `pendingState->link.next = nextState`; as s32 that
write tears into the adjacent field_A4C (the auto-fire cadence timer, rewritten
every frame). After enough double-buffered fire cycles field_A48 holds a value
that is neither 0 nor a valid pointer, so the `else if (field_A48 == 0)`
re-arm gate never fires again and no further player gunshot is issued.
Evidence: user Bunker audiotrace.log — silenced-PP7 idx-46 sndPlaySfx requests
stop dead at log line 18930/25086 while all other SFX continue; the player-gun
slot 0x70076630 is then caught holding a torn value 0x000001db00000000
(field_A48=0 + field_A4C=0x1db read as one word).
Fix (D3x ABI/layout, #ifdef PORT): declare field_A48 as ALSoundState* under
PORT, s32 verbatim under #else. hands[] is runtime-only state (g_CurrentPlayer),
never ROM-serialized, and all downstream fields are accessed by member name —
widening 4 bytes is layout-safe. The (struct ALSoundState *) casts at the use
sites become no-ops and stay for a minimal diff.
Build clean (gunfire.c + full link). Runtime verification owed: replay the
Bunker firefight, confirm idx-46 requests continue for its full duration.

D205: CLOSED (M-78). User re-tested explosion->scream on Bunker after the
PR #28 merge — the explosion SFX is correct by ear now. All four D205
symptoms were D206 (the +1 bank-slot alias); the "scream" was a coincident
guard death-yelp (faithful N64 behaviour). M-74's pan audit already ruled
out a presentation-layer bug.
D207: re-add ONLY the [D207-DROP] trace line (not the reverted last-resort
LOOPED-preemption pass) at both sndDisposeSound no-voice sites in snd.c,
gated on GE_AUDIOTRACE, logging state/prio/flags/count=N/max — so a user
capture on the real failing level is decisive between (a) heavy-level 8/8
starvation, (b) a leak on an alarm-stop path, (c) perceptual. Static
re-check noted in findings D207: ALARM3 slot 162 sampleVolume=80 (below
gunfire), keyMax=8 => not RETRIGGER => continuous-loop by design on N64 too.
findings-index.csv regenerated.

User by-ear A/B vs N64 confirms D206: armour pickup, unarmed melee whiff
and silenced PP7 all correct. D202's silenced-PPK 'slap' was D206 (SFX
bank index +1) — CLOSED; M-65/M-66b ownerless-loop mitigations stay.
D205 narrows to symptom (2) explosion->scream only. D207 (alarm klaxon)
acceptable in play per user; voice-starvation hypothesis didn't hold up
(M-77b), no fix shipped, GE_FORCEALARM probe kept for follow-up.
Regenerated findings-index.csv.
The D117 findings.md addenda in the prior commit changed D117's status
text without regenerating findings-index.csv, and the new GE_DETERM_TRACE
env var wasn't yet mentioned in GE-ENV-PROBES.md -- both fail their
--check gate in CI's validate job. Caught by a real CI run, not predicted.

Static/tooling slice of docs/dev/notes/AGENTIC-SPEEDUPS-PLAN.md — no build or
runtime environment needed to verify any of it.
- Step 6 / N7: add a VERIFY: line to the investigation-brief template
(docs/dev-process.md) and the CLAUDE.md dispatch-preflight checklist — the
brief must now name the exact probe/verify invocation that proves the task
done, or state that runtime verification is impossible here.
- Step 4 / N2: tools_pc/README.md — indexes the ~60 scripts with a
living vs artifact marker so closed-finding artifacts can be archived.
- Step 4 / R8: tools_pc/gen_findings_index.py -> docs/dev/findings-index.csv
(label, bucket, one_liner, status_raw) — grep-before-you-read aid for the
~200 KB finding log. Heuristic parser of the §F/§H tables.
- Step 4 / R9: tools_pc/gen_env_probes.py — re-greps live getenv("GE_*")
sites and reports NEW/GONE drift vs docs/dev/GE-ENV-PROBES.md (keeps the
curated prose, only checks the site map). Doc reconciled: 7 new probes
added, GE_D54 kept as a tombstone.
- CI: validate job now runs both generators with --check.
Step 1 / N1 (HANDOFF preflight) applied in the local-only docs/HANDOFF.md.
Step 2 (verify.sh) and the HANDOFF/HANDOFF-ARCHIVE trim are left for a
session with a build environment.
