+"""gen_voicebox_truth.py — freeze/replay truth for the voicebox literal-100%
+residue (dichotomy wave #2479, final lane).
+
+Freeze mode (default): drives the LIVE Python oracle (src/rune/voicebox.py)
+and records effect rows into src/go/voicebox/truth.json:
+
+  * legacy surface (handle_hook, PLUGIN manifest) — regenerated from the
+    live module attributes so the whole file is generator-owned.
+  * _run — argv law ([VENV] + args) + the default kwargs ({}) via a
+    subprocess.run capture.
+  * push-to-talk — the nested talk() closures (start_recording,
+    stop_recording, _transcribe_and_type, on_press, on_release) driven
+    through a pynput rig: fake keyboard.Key sentinels + a Listener that
+    captures the real closures, so every case exercises the oracle's own
+    nested functions over the oracle's own `recording` dict. Device IO
+    (NamedTemporaryFile, arecord Popen, faster_whisper, xdotool, stderr)
+    is patched at the oracle's module globals; temp files are REAL files
+    (fixed per-case roots) so os.path.exists/getsize/unlink run unpatched
+    — only the absolute root is normalized to TMP/ in the frozen rows.
+
+Replay mode (--replay <path>): re-runs the same scenarios against the
+frozen file (regen byte-stability gate; the Go battery replays the same
+rows via VB_TRUTH_PATH for live parity).
+
+Determinism laws: fixed temp roots (no mkstemp randomness), per-case
+counters reset, no clocks (the module is clock-free), stderr captured per
+case. The oracle's import-time venv re-exec is guarded (the dedicated
+venv must not exist — freeze halts loudly if it does).

+//   - start_recording sets active=true BEFORE the temp/spawn, so a failure
+//     leaves the partially-mutated state the oracle leaves.
+//   - stop_recording clears tmp BEFORE the size probe; the elif-wav unlink
+//     swallows errors (OSError → pass); size gate is >4000, strictly.

+//     xdotool runs check=True — its failure lands in the SAME except arm
+//     as a whisper failure ("transcribe error: …"), and finally ALWAYS

+# voicebox — literal-100% residue verification summary (rune-wave-f2)
+
+Module: voicebox (GO). Oracle: src/rune/voicebox.py (164L, 11 fns, was 5/11).
+Residue ported name-preserving (exact snake names, tool_protocol gaps.go law):
+_run, start_recording, stop_recording, _transcribe_and_type, on_press,
+on_release — the talk() nested closures, pure control logic 1:1, device IO
+(arecord Popen, faster-whisper, xdotool, NamedTemporaryFile, unlink, stderr)
+behind the voiceboxSeams injectable; the pynput listener loop stays facade.
+
+## Changes
+- src/go/voicebox/gaps.go — the six ports + seams + recording twin.
+- src/go/voicebox/main.go — replay loop extracted (runReplay/loadCases);
+  new ops: run, push2talk, talk_banner.
+- src/go/voicebox/battery_gaps.go — fake-seam harness mirroring the
+  generator rig; replays the frozen effect rows.
+- src/go/voicebox/main_test.go — TestTruthReplay (VB_TRUTH_PATH override),
+  TestRunArgvLaw, TestPush2TalkGuardLaws.
+- src/go/voicebox/truth.json — REGENERATED generator-owned (21 cases: 7
+  legacy incl. talk_banner, 3 _run, 11 push2talk).
+- scripts/gen_voicebox_truth.py — freeze/replay generator (pynput/tempfile/
+  subprocess/faster_whisper rig; real temp files; TMP/ + REPO_ROOT
+  normalization; venv re-exec guard).
+
+## Verification (all in this checkout)
+- Freeze: frozen 21 cases; regen x2 BYTE-IDENTICAL; --replay mode 21/21
+  stable (verification/vb-freeze-verify.txt, vb-freeze.log,
+  vb-replay-stability.log). Shared-harness --verify N/A: op-format rig
+  truth (regen-stability + live battery are the freeze gates, project_
+  registry precedent).
+- Go battery: TestTruthReplay/TestRunArgvLaw/TestPush2TalkGuardLaws PASS
+  (vb-gotest.log rc=0); gofmt clean (vb-gofmt), go vet clean (vb-govet),
+  go build clean (vb-gobuild); binary replay: PARITY OK 21 cases.
+- Live parity 100%: fresh oracle regen → /tmp/vb_live_truth.json (byte-
+  identical to frozen) → battery green against it (vb-parity.log).
+  Divergence found+fixed en route: Go calledProcessError dropped the
+  quotes around the python list repr — battery caught it (case 19), fixed
+  to "Command '[…]' returned non-zero exit status N.".
+- Python both pins: adjacent pytest has no voicebox importer (plugin
+  surface — task_gate precedent); gates = canary + battery. Canary
+  verbose: ✓ Import voicebox BOTH pins (vb-canary-{live,pin}.log; the 3
+  remaining canary failures are sibling .so contracts — witness/
+  claim_audit cognition_core+evidence_provenance — identical both pins,
+  unrelated). Adjacent suite test_p1_03_memory_selection.py (exercises
+  warm_neuron_store via the selector): 67 passed/1 skipped BOTH pins
+  (vb-pytest-adjacent{,-pin}.log) after building memory_scoring +
+  memory_retrieval .so in this worktree (retired-oracle stubs recurse
+  without them — worktree artifact, not a regression; main checkout
+  passes with its prebuilt .so's).
+- Audit delta: voicebox 5/11 → 11/11 (missing list empty).
+
+## Divergences (documented, not bugs)
+- handleHook empty-event validation improvement (pre-existing, pinned by
+  hook_empty_oracle).
+- stop_recording stats the wav ONCE (fileState seam); the oracle's
+  exists-then-getsize TOCTOU window is unreachable single-threaded.
+- on_press/on_release suppression is recover()-based (oracle: except →
+  logger.debug, silent unconfigured).
