From b6649848a6329bd788637ab286bd32d6c1016d6d Mon Sep 17 00:00:00 2001 From: Shay Date: Sun, 17 May 2026 15:51:59 -0700 Subject: [PATCH] =?UTF-8?q?feat(adr-0024):=20Phase=205=20=E2=80=94=20strat?= =?UTF-8?q?ified=20mechanism-isolation=20across=205=20failure-mode=20famil?= =?UTF-8?q?ies?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Authors a 20-case corpus stratified across five geometric failure-mode families and a separate 10-case benign corpus for the EXHAUSTION_CEILING lane: A. near_forbidden_correct_endpoint (6 cases, gaps 0.002 to 0.55) B. near_equal_admissible (5 cases, diffs ≤ 0.01) C. no_admissible_path (3 cases, honest refusal) D. multi_step_admissibility (3 chained cases) E. heterogeneous_relation (3 chained cases, blade-switching) phase5_runner runs each case under BOTH threshold and ADR-0026 margin modes and reports per-family pass_rate, refusal_rate, and (for Family A) rejection_traced_rate + boundary_overridden_rate. Headline: pass_rate_threshold = 1.00 (20/20) pass_rate_margin = 1.00 (20/20) mechanism_isolated = true (both modes, all five families) replay determinism = byte-identical across 3 reruns Family C refuses with RefusalReason.INNER_LOOP_EXHAUSTION in both modes (load-bearing evidence for ADR-0024 Phase 2 typed refusals). Family B refuses under margin mode (validates ADR-0026 δ=0.4 gate). Benign inner-loop corpus for EXHAUSTION_CEILING ≤ 0.05 gate: boundary_only: exhaustion 0.00, pass 1.00 null_control: exhaustion 0.00, pass 1.00 inner_loop_t0: exhaustion 0.00, pass 1.00 inner_loop_tpos: exhaustion 0.00, pass 1.00 (threshold 0.25) Geometric finding documented while authoring the benign corpus: 23 of 85 pack tokens have negative self-cga_inner under Cl(4,1). Tokens with self-score ≤ 0 cannot serve as single-token expected endpoints in threshold mode — the algebra's Lorentzian signature forbids this geometrically. Phase 5 benign corpus draws expected endpoints from the 62-token positive-self-score subset. This is consistent with Phase 4 characterization: no static threshold delivers separation_quality ≥ 0.8 — the margin lane survives because margin compares differences, not absolute scores.

That is a binary signal: it cannot tell us *which kind* of +failure-mode the mechanism handles cleanly versus where the gate +behaves accidentally. Phase 5 stratifies the corpus across five +geometric failure families so each lane reports its own pass rate, +refusal rate, and rejection-traced rate. + +The stratification also de-risks ADR-0026's δ = 0.4 choice: if a +family surfaces blade-gaps below 0.4 that *should* admit, the corpus +will show a margin-mode refusal in that family, and we report the +architectural finding rather than patching δ per family. + +## Families + +| Family | Geometric construction | Threshold-mode expectation | Margin-mode expectation | +|---|---|---|---| +| **A. near_forbidden_correct_endpoint** | expected blade-score > forbidden by a small margin (0.002 to 0.55) | admit expected | admit if gap ≥ δ=0.4, else refuse | +| **B. near_equal_admissible** | two admissible candidates within ≤ 0.01 blade-score | admit either (tie-break stable) | refuse (diff < δ) | +| **C. no_admissible_path** | both candidates score ≤ 0 against blade | honest refusal (INNER_LOOP_EXHAUSTION) | honest refusal (INNER_LOOP_EXHAUSTION) | +| **D. multi_step_admissibility** | chain of two Family-A configurations | each step admits expected | margin-mode handles each step on its own δ test | +| **E. heterogeneous_relation** | chain with *different blades* at each step | each step admits under its own blade | each step admits under its own blade | + +## Headline numbers + +| metric | threshold mode | margin mode (δ=0.4) | +|---|---|---| +| overall pass_rate (20 cases) | **1.00** | **1.00** | +| mechanism_isolated | true | true | + +Per-family pass_rate is 1.00 for both modes across all five families. + +## Mechanism-evidence detail (Family A) + +Within Family A (6 cases) we additionally surface two diagnostic rates: + +| diagnostic | rate | +|---|---| +| `rejection_traced_rate_threshold` | 0.50 | +| `boundary_overridden_rate_threshold` | 0.50 | + +Reading: in three of six near-forbidden cases the boundary already +prefers the expected token (so the inner-loop never *had* to reject +the forbidden — selection just succeeded). In the other three, the +boundary picks the forbidden, the inner-loop *does* reject it, and +the rejection is visible in the trace. Both halves are honest: +ADR-0024 does not promise rejection in every Family-A case; it +promises that *when* boundary diverges from blade-aligned ranking, +the inner-loop overrides it with rejection visible in the trace. + +This is the kind of granular evidence that Phase 3's single +mechanism-isolation flag cannot surface. + +## Family C — refusal contract + +All three Family C cases refuse in both modes with +`RefusalReason.INNER_LOOP_EXHAUSTION`. This is the load-bearing +evidence for ADR-0024 Phase 2's typed-refusal pipeline: when the +admissibility region contains no positive-scoring candidate, the +honest path is exhaustion, not silent boundary fallback. + +## Family B — margin gate is doing real work + +All five Family B cases admit under threshold mode and refuse under +margin mode. Without ADR-0026 (margin), the corpus would silently +accept a near-tie selection; with it, the runtime surfaces the +ambiguity via honest refusal instead of an arbitrary tie-break. + +## δ=0.4 falsifiability check + +δ=0.4 was chosen in ADR-0026 from the minimum Phase 3 v2 margin +(0.456). Phase 5 adds 15 single-step cases plus 5 chain cases +covering blade-gaps from 0.002 to 0.55. No case surfaces a blade-gap +below δ that *should* admit (i.e., the corpus does not falsify the +δ choice). Cases A-001 to A-004 have gaps below δ and they all +refuse under margin mode — which is the *intended* behavior under +ADR-0026, not a counterexample. + +If a future PR adds a case with blade-gap < 0.4 where margin-mode +refusal is the *wrong* behavior, that finding must be reported in +this document as a δ-falsification rather than patched per-case. + +## Replay determinism + +`tests/test_phase5_corpus.py::TestReplayDeterminism::test_margin_mode_three_run_byte_identity` +runs the lane three times and asserts per-case selection identity +across all three runs. All 20 cases pass — Phase 5 preserves the +ADR-0024 deterministic-replay invariant under both threshold and +margin modes, single-step and chained. + +## Benign inner-loop corpus (EXHAUSTION_CEILING lane) + +`evals/forward_semantic_control/public/inner_loop_benign/cases.jsonl` +(10 cases) is the benign single-step corpus the +`EXHAUSTION_CEILING = 0.05` gate in `inner_loop_runner.py` was +designed against. Result on this corpus +(`results/phase5_benign_inner_loop_report.json`): + +| condition | exhaustion_rate | pass_rate | gate | +|---|---|---|---| +| boundary_only | 0.0000 | 1.00 | OK | +| null_control | 0.0000 | 1.00 | OK | +| inner_loop_t0 | 0.0000 | 1.00 | OK | +| inner_loop_tpos (t=0.25) | 0.0000 | 1.00 | OK | + +### Geometric finding surfaced while authoring this corpus + +Cl(4,1) is Lorentzian — 23 of 85 pack tokens have **negative** self +`cga_inner` (most negative: `mean = -2.01`, `verify = -1.33`, +`context = -1.15`, `corrects = -0.74`). This means a single-token +admissibility region with `chain_tokens = [tok]` can geometrically +forbid its own answer: if `cga_inner(versor(tok), versor(tok)) < 0`, +threshold-mode inner-loop refuses even with `threshold = 0`. + +The Phase 5 benign corpus draws its 10 expected endpoints from the +62-token subset with `self-cga_inner > 0.25`. Tokens like +`correction`, `verify`, `context`, `mean`, etc. cannot serve as +single-token expected endpoints under static thresholding — they +need either a different region shape (multi-token chain whose outer +product realigns the blade) or the ADR-0026 ranked-with-margin +mode, where the ranking metric is robust to per-token sign quirks. + +This finding is consistent with the Phase 4 characterization result +that no static threshold delivers `separation_quality ≥ 0.8` across +v1+v2 — the algebra's signature itself resists static thresholds in +the general case. The δ=0.4 margin lane survives because margin +compares score *differences*, not absolute scores. + +## What this does *not* prove + +* Rotor-side admissibility (ADR-0025) is exercised in `tests/test_rotor_admissibility.py` + but Phase 5's region construction does not set `frame_versor`, so + this corpus does not exercise the rotor-admissibility gate. A + future Phase 5.1 may add a sixth family for frame-cone refusals. +* The benign corpus is intentionally narrow (single-token regions + drawn from positive-self-score tokens). Broader benign corpora + with multi-token outer-product blades remain an open question — + Phase 5 does not claim that static thresholds work *generically*, + only that they work on this curated
