Review/ratification pass over the 6-phase afferent environment-falsification
roadmap (rebased onto D-inclusive main). The roadmap validated green: smoke (90),
architectural invariants (56), the full sensorium suite, all phase tests, and the
four eval lanes (environment-falsification / event-vision / vision / sensorimotor)
report failed:0. A five-lens adversarial review found the efferent gate
fail-closed (default-deny, conjunctive safety∧ethics∧tool_scope, refuses before
the decoder, hash-only traces, no real decoder, no overclaim), the afferent
Phases 1-5 read-only (runtime import-guards + frozen dataclasses), and the
expected-artifact obligations deterministic + meaningfully-failing. Two
reconciliations from that review:
1. Witness-log importer trust boundary (sensorium/logs/importer.py). The offline
JSONL importer now rejects malformed input with a deterministic ValueError
instead of a raw JSONDecodeError/KeyError, names the 1-based line on a bad
JSON line, rejects non-object records and non-integer ticks, and size-caps the
file (8 MiB) so an oversized log is refused rather than read whole. The trust
boundary is now stated in the module + function docstrings. Behavior for VALID
logs is byte-identical (the environment-falsification lane hashes are
unchanged). New rejection-path tests added.
2. ADR-0198 reconciliation. The §3 verdict-enforcing GATE mechanism
(VerdictEnforcingEfferentGate + MotorActionIntent) has now landed, so the
Implementation Status is amended to say so — while being explicit that the §3
lowering itself (deriving verdicts from the ADR-0029/0033/0036/0037 governance
packs), the motor decoder (every adapter is decoder=None), and ratification by
the dedicated motor governance ADR (now drafted as ADR-0216, Proposed) all
remain deferred. No physical motor decode is authorized.
Disjoint from the GSM8K serving path and from Step D (generate/determine|realize,
chat/runtime, core/config) — clean rebase, no overlap.
DefaultEfferentGate is a capability/shape pre-filter only; it does not
lower decoded actions into safety/ethics pack verdicts (ADR-0198 §3 /
§1.2 Gap B). ModalityRegistry.decode/decode_batch now refuse fail-closed
any emission through a gate whose enforces_action_verdicts is False,
unless an explicit allow_unverified_efferent sandbox opt-in is set.
A real motor decoder thus cannot emit through the capability-only gate;
the §3 verdict-lowering gate must be built and installed first. No
production caller of the decode path exists today, so this closes the
latent hazard before a motor decoder makes it load-bearing. Adds two
falsifiable tests (fail-closed refusal; verdict-enforcing gate allowed).
Disjoint from the GSM8K serving path.
Implements ADR-0181 PR-6 (eval-plan §4): teachers label or align; they never
define the substrate and never fold embeddings into the versor path.
- sensorium/audio/teachers.py:
- TeacherHint: typed, versioned, checksummed annotation (no raw embeddings).
- AudioTeacher protocol (pure on the signal).
- attach_teacher_hints: the ONLY admission path — appends content.* anchors to
the IR's content_anchors (immutable, recomputes ir_sha256). content.* is not
an operator key, so compile_events skips it: versor + projection_sha256 stay
byte-identical; only the ir leg of the merge_key moves (evidence recorded).
- KNOWN_TEACHER_LANES (whisper/nemo/clap/encodec): declared + gated behind
optional extras; load_teacher import-guards and fails loudly (never a silent
fallback). StubTranscriptTeacher is the deterministic reference instance.
- parser.py: extract _ir_payload + ir_sha256_of (DRY single source of truth for
ir_sha256; byte-identical to parse() output — regression-guarded).
- pyproject.toml: audio-whisper/nemo/clap/encodec optional extras (never
runtime-required).
16 failable proof tests in tests/test_audio_teachers.py. Load-bearing:
test_teacher_hint_does_not_change_versor. Mutation-verified — giving a teacher
anchor an operator event_type (folding it into the versor) fails the
versor-invariance proof; reverted, all pass.
Additive only (ADR-0013): no core layer touched. Audio suite 57/57; eval-gate
ir_sha256 pins unchanged by the parser refactor; architectural invariants 40/40.
Real model adapters are deferred until extras+weights are present; this PR ships
the policy, the typed-hint contract, and the shadow-only guarantee.
Add ManifoldState (N,32) versor field over graph edges, GraphDiffusionOperator
with damped convergence via construction_seed_versor closure, deterministic
hash-to-versor stub, and run_pulse.py end-to-end script proving injection →
propagation → vault recall → token output. 24 new tests, zero regressions
on architectural invariants.
