Rings 2 and 3 of the ADR-0246 preflight §9, built exactly as the brief bounds
them. ADR-0247 + ADR-0248 both **Proposed** — no self-Accept.
Ring 2 (core/ports/residual_protocol.py — ADR-0247):
the 7-stage shared control grammar: witness -> typed residual decomposition
-> permitted operator selection -> bounded operation or abstention ->
re-certification -> action decision -> append-only replay record.
Port-agnostic (no registry, no unified scheduler — §7 non-goal #2 honored);
v1 operators are ZERO-BOUND only (nonzero fails closed — no-silent-correction
doctrine); unaccounted residual fails closed; re-certification RAISES on
witness drift during a zero-bound pass; replay chain is append-only,
full-SHA-256 content-addressed, tamper-evident (verify_replay_chain).
NOTE: named core/ports/ because core/protocol/ is the existing CTP v0 wire
format (collision checked before naming).
Ring 2 adapters (core/ports/adapters.py): IdentityPort (ADR-0246 grade-1
geometry; typed channels travel IN the witness so decompose is a pure
re-shaping, no hidden state; admit = evaluate_admission, single source of
truth) + PrecisionPort (ADR-0244 §2.5 cast transport; ServingState subjects)
— two genuinely non-identical native geometries + a synthetic third port
proving grammar agnosticism.
Ring 3 (core/ports/integrity_handoff.py — ADR-0248):
the coordination seam ('Integrity coordinates handoffs; it does not replace
content-bearing cognition'): fuses Ring-2 port decisions + existing
EpistemicState/NormativeClearance into content-free proceed/hedge/abstain
(conjunctive, strongest-restriction-wins; fail-closed on missing/invalid
evidence; binds replay-chain tip digest; handoff itself content-addressed).
Weak epistemic standing hedges (mirrors hedge doctrine) — only integrity
violations silence a turn. OBSERVE-ONLY: no serve consumer yet; that is a
future flag-gated unit. Remaining Ring-3 programme honestly listed open
(world-model, governed-learning consumption, discourse widening).
Both pure/deterministic/off-serving (A-04 pinned); brief §0a/§9 updated.
[Verification]: uv run core test --suite smoke -q => 176 passed; Ring 2/3 +
ADR-0246 suites + D4 gate surfaces => 125 passed (28 new Ring-2/3 pins);

Opus 4.8 audit of Fable's slice-1 scaffold + authorized hardening (Step 2).
Stacked on feat/adr-0246-slice1-scaffold. Not a PR, not merged, no status flip.
AUDIT (Step 1) — VERDICT PASS. Re-derived A(F)/d_orth/d_stab/typed channels from
§3.1/3.2/3.6 independently: BIT-EXACT vs impl (0.00e+00). Confirmed in code (not
just comments): H_id={I} locked (singleton hardcoded, no enlargement path); path
composes lawful only, refused=break marker, never raw, never soft-I; no §7 scope
creep; serve byte-identity. Finding F1 (doc, not bug): composition uses the raw
CERTIFIED action (required for §6.2 accumulation, else A_path≡I detects nothing) —
now documented for ADR ratification.
HARDENING (Step 2):
§3.7 pure surface (identity_action.py): AdmissionPolicy (calibrated flag),
evaluate_admission (admit-or-abstain, no corrector); CERTIFIED_GAMMA_ID pinned
== identity._WAVE_LEAKAGE_BOUND; all other bounds UNCERTIFIED placeholders.
§3.7 SERVE WIRING (Steps 2.1/2.2): new default-off flag identity_action_surface
(config); threaded chat/runtime -> check -> _wave_field_score; refusal folds
into flagged -> existing would_violate/conjugate_correct abstains; IdentityScore
gains action_surface_active/d_orth/d_stab (legacy defaults). Flag-off is
byte-identical (D4 gate surfaces green unchanged; smoke 176 post-wiring).
§6.3 DISCRIMINATION REPORT (evals/adr_0246_discrimination) — HONEST numbers:
benign pass 0.00, false refusal 1.00, adversarial detect 1.00, control pass
1.00; d_stab AUC 0.375 (95% CI [0.15,0.62]) — BELOW chance. Benign cognition
sits ~18x farther from the frame (mean d_stab 27.8) than the attacks (1.55).
The gate refuses everything and does NOT discriminate; must stay off; usable
separation needs the §11 grounding work, not threshold tuning. Claims language
enforced: 'lawfulness relative to the declared frozen frame', NOT 'semantic
inalienability'.
Ledger raw-sneak hardening test (Step 2.3): mixed lawful/refused sequence must
equal the lawful sub-product, fails if raw sneaks into A_path_lawful.
Handoff to Sonnet: §4.1 per-turn record, path-ledger serve integration, ADR-0246
body + acceptance packet (Proposed, no self-Accept), §11 grounding-feasibility.
[Verification]: uv run core test --suite smoke -q => 176 passed (post-wiring);
ADR-0246 suites 80 passed; egress wiring + D4 gate surfaces 47 passed
(byte-identity); §6.1/6.2 eval 14/14; discrimination report numbers above.
See docs/audit/adr-0246-slice1-opus-audit-and-hardening.md + run log.
BOUNDED AUTONOMOUS SCAFFOLD DRAFT (Fable 5) — not a PR, not merged, no status
flip, no main push. For Opus 4.8 + Shay audit before anything proceeds toward main.
Stacked on the verified §3-primitives + §3.4/3.5-ledger stack (reuse, not re-derive;
all descend from main @ 04d67ca5).
Adds (directive steps 3-4):
+ evals/adr_0246_geometric_suite/ runnable §6.1 synthetic geometric suite
(identity, pi-inversion, 90deg-permutation, mild drift, alien tilt e14,
boost e15, near-singular Gram, malformed F) + §6.2 path/holonomy suite
(lawful sequence, small-rotation session accumulation, interleaved refuse,
pack-change hard break, raw!=lawful forensic). 14/14 cases pass.
+ tests/test_adr_0246_geometric_suite.py pins every case + explicit §6.1 pins
(pi-inversion s=-1, 90deg s=0, near-singular Gram error, malformed-F error)
+ identity_manifold.py: MalformedVersorError + _validate_versor guard on
induced_action / typed_residual_energy (§6.1 fail-closed on malformed F)
+ docs/handoff/adr-0246-slice1-scaffold-notes.md placeholder list, §5-§7
uncertainties, constraint-compliance record, explicit Opus/human TODOs
+ docs/audit/artifacts/adr-0246-slice1-scaffold-runlog.txt actual run output
Constraints honored: H_id={I} only; no soft-projection of unlawful A; path
composes lawful actions only (never raw product); no C_id corrector; chat/runtime,
flags, D4 gate wiring untouched (A-04 quarantine pinned); no discrimination report,
no ADR body, no claims language (deferred TODO: Opus/human); D4 plan not modified.
epsilon_turn/epsilon_session are UNCERTIFIED PLACEHOLDERS, never baked into a
module default (PathBudget is caller-supplied) — flagged in notes + run log.
[Verification]: uv run core test --suite smoke -q => 176 passed;
python -m evals.adr_0246_geometric_suite => 14/14 all_passed;
ADR-0246 suites + adjacent D4 identity surfaces => 114 passed (see run log).
