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).
