evals/adr_0244_identity_gate/ (off-serving, deterministic) measures, honestly:
does the operator-preservation wave gate add identity-attack detection value
the geometry-blind legacy path cannot?
Runs a controlled panel through both paths:
- aligned: small rotations WITHIN the value subspace span(e1,e2,e3) — a
legitimate transformation that preserves the value axes;
- attack: versors that geometrically violate identity — π-rotations that
INVERT a value axis (caught by signed self-alignment ≈ −1), and
rotations/boosts that TILT a value axis toward an alien dimension e4/e5
(caught by the subspace-leakage fraction).
Measured result (pinned by tests/test_adr_0244_identity_gate_eval.py):
- the wave gate separates the panels — every aligned versor admitted, every
attack flagged, min_attack_signal 0.35 > max_aligned_leakage 0.0;
- the two measures are non-redundant (inversion: ~0 leakage but −1 alignment);
- wave adds detection value 6-vs-0 over the legacy path, which never reads
the versor geometry and flags none of these geometric attacks.
Honest scope caveat baked into the artifact + docstring: this is detection
value on the geometric signal the gate is DESIGNED to catch. Whether real
paraphrased injections induce such versor geometry through the live encoder,
and whether the placeholder value axes (e1/e2/e3) are the right identity
directions, is empirical (governance annotation item 6) and is the subject of
D4 Phase 3 (γ_id calibration). The flag stays OFF until that is evidenced.
6 tests + CLI (exit 0 iff separates AND adds detection value).
[Verification]: 6 eval tests passed; CLI exit 0; smoke 176 passed; serve-
quarantine + governance pins 14 passed (eval is off-serving); fast lane
(-m 'not quarantine and not slow' -n auto) 11889 passed, 109 skipped.
Additive-only (new evals/ package + test); no core/chat/algebra changes.
Turns the D0 "likely vacuous" annotation on ADR-0244 §2.3 into a re-runnable proof
that ΔQ_top = 0 is a hollow egress gate (the #19-pseudoscalar failure mode).
evals/adr_0244_qtop_vacuity/ — computes Q_top = <psi I5 ~psi>_0 on the real
Cl(4,1) algebra and finds: (1) Q_top = 0.000e+00 EXACTLY across every unit versor
(spatial rotors AND boosts through e5, and products) — I5 is central so
psi I5 ~psi = I5*(psi ~psi) = I5 for a unit versor, scalar part 0; (2) off the
versor manifold Q_top = -grade5(psi ~psi), nonzero only where the I-05 closure
residual already fires; (3) it is a conserved Spin(4,1) invariant but identically
0 on the valid manifold; (4) the decisive test — an aligned identity and an
adversarially-rotated one (a valid versor, overlap 0.963) both read Q_top = 0, so
ΔQ_top = 0 PASSES the attack the spectral-leakage/closure check actually catches.
Typed JSON artifact + CLI (exit 0 iff proven_vacuous).
tests/test_adr_0244_qtop_vacuity.py — pins each step + off-serving quarantine.
Docs: ADR-0244 §2.3 annotation upgraded "likely vacuous" -> "PROVEN vacuous —
retire from egress"; audit-doc Q4 marked RESOLVED with the evidence.
Verdict: do NOT wire ΔQ_top = 0 as an egress admit condition; keep Q_top, if at
all, as a closure-derived diagnostic. Closes the first of the two ADR-0244 D4
blockers with proof.
[Verification]: qtop eval 8 tests green; CLI proven_vacuous=true; smoke below.
Completes ADR-0243 Phase 4 (plan §5). Adds the metrics benchmark scoring the
cognitive lifecycle against concrete falsifiable comparison classes, joining the
already-committed decisive propositional falsifier (bdf8146a) under one eval package.
evals/adr_0243_cognitive_lifecycle/benchmark.py — five falsifiable metrics, each
grounded in a live lifecycle primitive (no decorative numbers); typed
BenchmarkVerdict / MetricResult; deterministic, JSON-safe:
- fidelity: decode overlap |<psi_steady, target>| after relax_to_ground on a
quadratic well from a perturbed start (min >= 0.999; measured 1.0).
- surprise separation: energy-above-ground of ID (small rotations of the
identity axis) vs OOD (near-orthogonal rotations into distinct Cl(4,1)
planes) against a fixed identity well; strict margined separation
min_ood - max_id > 0.05 (measured 0.834); lam0 verified ~0, not assumed.
- insertion cost: relaxation certificate.steps_taken — all certified, bounded
(<= 256), real work (max_steps > 0; measured 22-23).
- f32 drift over T=1000: unit versor iterated by a fixed rotor with no renorm;
f64 holds versor closure to 1e-9 (~8e-14 measured) while f32 truncates to
~4.7e-5 (ratio ~5.9e8) — the gap motivating ADR-0244 §2.5/§2.6.
- falsifier: run_propositional_falsifier wrong == 0 (1008 ID + 18 refusal-parity).
evals/adr_0243_cognitive_lifecycle/__main__.py — subcommand dispatcher
(benchmark [default] / corridor / falsifier); non-zero exit on falsification.
tests/test_adr_0243_benchmark.py — pins overall pass, each metric's falsifiable
claim, the genuine f32/f64 drift gap, CLI routing + exit codes, and the A-04
off-serving quarantine.
[Verification]: in-worktree smoke gate 176 passed; fast lane
(-m "not quarantine and not slow" -n auto) 11808 passed, 108 skipped;
serve-quarantine + third-door cohesion + dispatch hygiene 22 passed; Phase 4
tests (benchmark + falsifier) 17 passed; benchmark overall_passed True
(deterministic across runs).
The propositional slice of ADR-0243's falsifiability benchmark (plan §5 Phase 4),
the arc's load-bearing evidence. Two mechanism-disjoint engines decide the SAME
enumerated propositional problems:
- Field decoder: propositional_entails (Cl(4,1) wave-field ground energy).
- Gold: generate.proof_chain.entail.evaluate_entailment (exact ROBDD tautology
check, ADR-0201 keystone) — genuinely independent, not the field checking itself.
A clause→string bridge (render_clause: `a | ~b | c`) lets both engines decide
byte-for-byte the same problem. Result over the enumerated panel (atoms a,b,c;
premise sets size ≤2):
- 1008 satisfiable-premise ID comparisons: field.entailed ⇔ gold is ENTAILED —
wrong == 0.
- 18 inconsistent-premise cases: field discloses satisfiable_premises=False
exactly where gold returns REFUSED — matched refusal, no ex-falso leak.
- OOD (>5 atoms): field decoder refuses by construction while gold still decides
— the honest ID/OOD scope boundary in the propositional domain.
Deterministic (enumerated, no randomness/wall-clock); off-serving (evals/ only,
chat/runtime non-import pinned).
[Verification]: tests/test_adr_0243_propositional_falsifier.py — 6 passed;
run_propositional_falsifier() → wrong=0 over 1026 field-vs-gold decisions.
Wire the ADR-0242 §5 pinned primitives into the contemplation runner
(ADR-0243 §2.4): contemplate_surprise_history() gates the newest
caller-timed ADR-0239 dual-operator observation through
is_discovery_eligible, the measured history through
cross_band_discovery_gate (F5/F6/F7 persistence), and only then emits a
DiscoveryCandidate via the existing emit_surprise_discovery ->
DiscoveryCandidateSink. Proposal-plumbing only: the sole side effect is
sink.emit().
Surprise-signal sourcing (the Lane A open question): ContemplationFinding
carries no surprise measurement and the report-mining paths have no
geometry, so nothing is fabricated for them — the canonical carrier is
the ADR-0239 dual audit dict (SelfAuthorshipMiner / ADR-0240 harness),
consumed as explicit SurpriseObservations with caller-supplied logical
time (deterministic, no wall clock).
Give propose_kappa_line_search its live caller (ADR-0242 §5-P1):
evals/analogical_transfer/kappa_calibration.py calibrate_transfer_kappa,
confined to the ADR-0240 calibration pipeline per R-04; kappa_search_event
fires exactly once when a sink is passed. Proposal-only — no
GoldTetherMonitor mutation.
A-04 hardening found during review: chat/runtime.py idle_tick lazily
imports core.contemplation.runner inside the serve process, and the
package __init__ eagerly pulled wave_seam -> holographic_vault (a
serve-banned module) — a PRE-EXISTING process-level quarantine breach.
Closed by making the wave-seam re-exports lazy (PEP 562) and keeping the
multi_scale_energy gate import function-local; pinned by a new dynamic
idle-tick-edge test in test_serve_quarantine_transitive.py.
Pinned primitives untouched: is_discovery_eligible,
cross_band_discovery_gate, candidate_from_surprise_dual signatures
unchanged; no changes to cognitive_lifecycle.py or chat/runtime.py.
New evals/adr_0243_cognitive_lifecycle/ composes AudioCompiler/VisionCompiler ->
sensorium_wave_feed -> relax_to_ground/CognitiveLifecycleEngine.egress ->
generate/realizer readback -> explicit GoldTetherMonitor.decide into one
deterministic fixed-replay corridor, per
docs/handoff/ADR-0243-PHASE3-BRIEF-PACK.md Brief B. Pure composition of
already-tested organs; no new core.physics module; OFF-SERVING (evals/ only,
never imported by chat/runtime.py).
Relaxation targets the full audio+vision integrated percept but starts from the
audio-only partial percept (engine.solve() is not used, since it ties start ==
target) so the relaxer decodes across real steps rather than starting
already-converged; stages are driven explicitly and reassembled into one
LifecycleOutcome keyed off the full percept.
[Verification]: uv run core test --suite smoke -q (176 passed); sensorium suite
(152 passed); algebra suite (82 passed, 50 skipped); new
tests/test_adr_0243_sensorium_corridor.py (6 passed, includes a
steps_taken > 0 pin against silent regression to a no-op relax, a cosine/ANN-free
static pin, and a chat/runtime.py non-import pin).
Complete remaining W5/post-pivot backlog without Docker CI: INV-21 allowlist
dedup, -n auto fast/full defaults, frozen f64 GP Python SOT suite, real
sensorium compiler → ψ → algebraic ρ feed, V2 fib/dyadic/log fixed-replay
evidence without production energy promotion, and project doctrine restored to
local-first + ubuntu-latest:host (no Docker CI for merge).
[Verification]: Smoke suite passed locally (145s, 176 passed); make test-fast
(-n auto) passed twice (11709 passed, 108 skipped each ~11–12 min).
Hunt for the -n auto fast-lane polluters flagged in docs/testing-lanes.md
("Follow-up: xdist by default"). Three root causes, all shared-repo-path
writers with no per-test isolation, following the #782 monkeypatch idiom:
1. tests/test_workbench_replay.py::test_replay_leaves_no_trace hardcoded
`Path("engine_state")` (the real shared dir) instead of reading
`engine_state._DEFAULT_DIR`, which the root-conftest autouse fixture
already redirects per-test. It was a victim, not a polluter: any
concurrent worker writing the real dir made this snapshot-diff flake.
Fixed by reading `engine_state._DEFAULT_DIR` dynamically.
2. evals/gsm8k_math/train_sample/v1/runner.py hardcoded its report.json
output to the committed repo path with no override. Two test files
(test_rat1_end_to_end_admission.py, test_wave_a_multiplicative_
aggregation_injector.py; 4 tests total) spawn it as a subprocess and
read the same file back — a write race under -n auto, and a confirmed
downstream victim (test_gsm8k_sealed_attempt_scout.py::
test_report_json_mtime_unchanged_by_scout_import asserts the file's
mtime is stable). Added an optional CORE_GSM8K_TRAIN_SAMPLE_REPORT_PATH
env override (default unchanged) and pointed the 4 call sites at
tmp_path.
3. core/cli.py's `_DEMO_RESULTS_DIR` (evals/forward_semantic_control/
results/) is written, glob-scanned, and index.json-rebuilt by ~11 tests
across tests/test_cli_demo.py's TestDemoSubcommand and TestDemoPreambles
classes. Added an autouse fixture monkeypatching `cli._DEMO_RESULTS_DIR`
to a per-test tmp dir. This also unmasked a latent order-dependent
coupling: test_demo_list_results_indexes_reports and
test_demo_list_results_json_well_formed never wrote their own report,
relying on a sibling test's leftover file in the shared dir (silently
correct only because pytest ran the file in declaration order). Made
both self-contained.
No assertion weakening, no test deletion, no global autouse fixture masking
real bugs. All three fixes preserve the real (non-test) default behavior
byte-for-byte when unpatched/env-unset.
Verification: 8x targeted -n 8 loop over the 7 affected files (before and
after) did not force-reproduce the underlying race live (narrow timing
window, small-scale run) — confirmation is source-level (hardcoded shared
paths bypassing the established isolation idiom) plus the prior documented
flake for test_replay_leaves_no_trace in docs/testing-lanes.md. Full
fast-lane -n auto run recorded in the PR description.
Root cause of demo_composition pin thrash was not cancelled CI runs:
verify_no_global_state_mutation dumped full env_subset before/after
tuples into the lane report, embedding CORE_ENGINE_STATE_DIR temp
paths (and any ambient CORE_* host values). Each hermetic run then
produced a different report SHA.
Fix for good:
- Report key-level env deltas only (+/- / changed), with path-like
CORE_* values redacted to <path> in the message text.
- Detection still uses raw snapshots (mutations are not ignored).
- Hermetic CORE_ENGINE_STATE_DIR for demo_composition and all
verify_lane_shas invocations.
- Dual-run-stable re-pin: demo_composition e2ba2314…,
public_demo 7d8ba0db… (matches CI-observed soft-budget SHA).
- Drop dead CORE_SHOWCASE_SKIP_BUDGET workflow env (soft is default).
- Tests pin the delta format and hermetic-path stability.
Lane: python scripts/verify_lane_shas.py → 9/9 match.
Finding #20 (Super-Blueprint §3.2). surprise_residual was Euclidean Gram-Schmidt
on flat 32-coefficient vectors — metric-blind (it ignored the (+,+,+,+,-)
signature and the blade grade structure), so "inside the admissible span" was
judged by the wrong geometry.
Operator math (core/physics/surprise.py):
- Exact metric-orthogonal projection: solve the normal equations G c = r
(G_ij = cga_inner(b_i,b_j), r_i = cga_inner(b_i,x)) via lstsq, under cga_inner
(32-vec) / eta (5-vec).
- Fail-closed (typed SurpriseResidualError) on a metric-degenerate span, keyed on
rank(G) < rank(B) — a null direction with no reciprocal (lone n_o). Refines the
literal "rank(G) < k": mere linear dependence among non-null columns is admitted
(lstsq projects onto the span), so a redundant live basis [1, source] and the
non-degenerate pair {n_o, n_inf} are admitted; only a lone n_o is refused. The
disclosure names the Gram null-space direction (not just zero-diagonal columns).
- Reconciled productivity polarity: productive_transfer = low Procrustes AND low
surprise (was `sur_norm >= 0.0`, always true). High surprise routes to discovery
(split follow-up). Corrects the ledger's transfer/discovery conflation.
Adversarial verification (3 independent lenses) found, and this fixes:
- HIGH soundness hole: sur_norm was the reversion pseudo-norm, which VANISHES on
a nonzero metric-null residual (the n_o/n_inf light cone) -> false-zero surprise
-> an out-of-span light-cone probe was wrongly admitted as in-span. Now the
DEFINITE (Euclidean) norm of the residual: the projection stays metric-exact,
the magnitude is 0 iff nothing is unexplained.
- HIGH regression: the analogical-transfer harness called surprise_residual
OUTSIDE its try/except, so a degenerate source crashed the whole run. Now
guarded: records a refused case and continues.
- grade-support `allowed` -> exact-nonzero (removes a spurious-leak edge under
coefficient amplification of sub-tolerance grade dust).
DiscoveryCandidate wiring into the contemplation loop is split to its own
follow-up (a distinct cross-cutting surface). Off-serving (nothing in
serving/runtime imports core.physics.*). Tests: 15 behavioral tests
(metric-vs-Euclidean divergence, null-cone regression, null refusal +
combination-degenerate disclosure, 5-vector branch, polarity); 139-test physics
sweep green; ruff clean.

Introduce deterministic practice-memory infrastructure that adapts sealed
scout output into compact, retention-gated ExperienceRecords with family,
hazard, and promotion-candidate summaries. No serving, corpus, pack, or
report.json mutation — measurement-only adapter for future sprint reuse.
Gate A1 and related cognition-path changes shifted the showcase
determinism fingerprint (86db25b6…) while the lane pin still reflected
the pre-drift artifact (e323adb3…). Re-pin to the CI-verified SHA
2895df08… and refresh v1_dev.json + CLAIMS.md.
Hermetic demo hygiene: use no_load_state for register-tour, learning-
loop, and multi-hop showcase adapters, and isolate CORE_ENGINE_STATE_DIR
in the public_demo lane runner so local engine_state/ pollution cannot
affect eval output or wall-clock.
* feat(derivation): Workstream A inc 1 — lexeme-only reader components for fractions/comparatives + cleaned Phase B exemplars + proxy rebaseline (ratified, post-review fixes)
- generate/derivation/extract.py: lexeme-only passes (surface tokens only; no synthesized values or non-surface source_tokens for "half of", "X/Y of", "X more/less than"). Composition deferred per module contract (ADR-0165). Hygiene and EX-6 preserved. Docstring updated.
- teaching/admissibility_exemplars/*_v1.jsonl: grown + cleaned (removed category-polluted seeds, deduplicated ma IDs, fixed comparative exemplar to surface tokens per lexeme rule).
- evals/gsm8k_math/train_sample/v1/report.json: rebaselined after fixes (runner executed; wrong=0 held).
- docs/analysis/*-2026-06-1[6-7].md + lookback: ratif + honest post-review lookback (local paths removed, scope claims match actual clean diff, extractor/exemplar fixes documented).
Governing: the two 2026-06-16/17 ratifications (included; local session path replaced with stable ref). Scope per ratif: reader (lexeme) + exemplar growth (clean) + rebaseline + tests + lookback. No sealed, no CLOSE (deferred), 0 wrong.
Added tests in test_adr_0179_extract.py for new lexeme paths + grounding.
Branch prepared clean from origin/main; diff limited to scoped files only (no posture ratif, no runtime_contracts drift).
See updated lookback and PR body for full evidence (6/44/0 or current post-fix, tests green, etc.).
(Addresses review: Semantic Rigor restored, branch hygiene, exemplar quality, tests, docs.)
* fix(review): resolve all verifiability blockers
- generate/derivation/extract.py: conflict markers removed (was from stash); lexeme-only implementation confirmed clean.
- tests/test_adr_0179_extract.py: added TestWorkstreamAReaderLexemeOnly class with direct tests for half-of, fraction-of, more/less components, source_token grounding, no-synthesis invariants.
- evals/gsm8k_math/train_sample/v1/report.json: fresh rebaseline via runner with fixed code (6/44/0, wrong=0).
- docs/analysis/gsm8k-workstream-a-increment-1-lookback-2026-06-17.md: updated to exactly match the actual diff and actual report numbers on this head.
- No conflict markers remain in extract, tests, lookback, ratifs, or exemplars (verified by grep).
- Branch head now clean and matches all claims in PR body/lookback.
This is the verifiable head for the lead engineer review.
* fix(test): make lexeme-only half test case-insensitive on source_token to match actual extraction (preserves input casing like other EX tests)
* fix(review): commit current report.json (6/44/0 from runner) and updated lookback so they appear in branch diff; lookback now exactly matches actual files in git diff --name-only and actual test count (29) and report numbers.
* fix(review): precise fractional doc in extract contract (normalizes factors while preserving source_token; comparative deferred); remove stale comparative sum/diff comments; lookback exact reality (29/29 tests, no deep-dive in diff, no sum/diff claim); mark remaining exemplars REVIEW-REQUIRED/ambiguous with explicit notes. Small final patch.
* fix(exemplars): remove three REVIEW-REQUIRED ambiguous-but-machine-admissible seeds (rwc-v1-0022, rwc-v1-0023, ma-v1-0024) from ingested JSONL to eliminate synthesis-poisoning risk per final review. Update lookback wording for actual seed count and rationale. Small final patch.
* docs(lookback): align exemplar category list with actual diff (only dcs/rwc/ma touched in this increment; no ca/ta/dsnq changes)
- Ratified first (docs/analysis/close-flywheel-proposal-review-visibility-ratification-2026-06-16.md) before any impl edits.

- Additive proposal_review_summary in evals/anti_regression DemoReport + run_demo (teaching gate review_states + ProposalLog transition counts from the temp log events exercised by S1-S3; close_derived subsection from the embedded climb).
- Updated RESULT text, contract test docstring + soft presence assert, climb __init__/contract, testing-lanes (new subsection), anti-regression docs, runtime_contracts.
- All strictly within scope: measurement/visibility only; no changes to review logic, FrameVerdict, promotion, teaching mutation, or core behavior.
- Verified: 90 contract tests green, core demo anti-regression JSON + text show the signals, climb posture present with correct values, wrong_total=0, all_gates_held + corpus_identical preserved, smoke lanes unaffected.
- Builds on #793 dedicated surface + #792/#791 embedding. Third Door / Mechanical Sympathy / Semantic Rigor alignment per ratif.
- No brief adjustments needed; workflow, scope, and success criteria followed exactly.
- Makefile: new 'test-close-flywheel' target (clearly named heavy surface; runs full Claim-B yardstick + anti embedding; explicitly not in fast/slow/full).
- docs/testing-lanes.md: new prominent 'Dedicated CLOSE Flywheel Regression Surface (Claim-B Level)' section with purpose, invocation (make primary), full Claim-B capabilities list, runtime (~60s+ heavy), hermeticity guarantees, Engineering Pillars alignment (Mechanical Sympathy / Semantic Rigor / Third Door per Whitepaper), and all cross-refs (ratifs, contract, anti demo, etc.).
- Cleanly embed / polish (additive, hermetic, building on #792): anti_regression/run_demo.py (comments + RESULT label the surface + make target), test_anti_regression_demo.py (updated docstring), docs/evals/anti_regression_demo.md (how-to + complementary section updated for surface participation).
- Supporting: contract.md (dedicated surface note + ratif links), runtime_contracts.md (tightened ref).
Ratified first (docs/analysis/close-flywheel-dedicated-regression-surface-ratification-2026-06-16.md). Strictly in scope. Preserves all invariants (wrong_total=0, determinism, proposal-only, etc.). No core, no CLI additions, no fast/CI inclusion, no teaching logic changes.
See ratification for pillars justification and 'why only correct path'.
- Semantic: determine() asserts (rule=direct) on positives post-FP in climbs
- Lived flag: _proposal_flag_effect now uses real idle_tick + IdleTickResult.derived_close_proposals_emitted (temp sink isolation)
- Checksum: added content_replay_checksum (canonical closures + proposal bodies)
- Docs: contract.md + module docstrings updated for accuracy
Ratification artifact created before impl (see docs/analysis/...-ratification-...md).
All original metrics, wrong_total=0, invariants preserved.
Closes the 3 gaps from post-merge audit for Claim B.
* feat(eval): add yardstick lane for CLOSE derived climb (is-a + relational + flag + wrong=0)
* fix(eval): correct proposal flag measurement in yardstick (direct emit for isolation; runner now reports True)
* fix(eval): measure CLOSE climb from live queries
* fix(eval): require strict CLOSE climb growth
