EM-XCT-09 R2 audit
Scope

Cumulative static read: full R1 non-upstream bodies plus the ten R2 deltas (classification_review.py, model-spec.md, spec.json two patches, tests/invariants/reports, adoption-limits.md, bindings/native-v3.md, research.md). Unchanged R1 bytes treated as still in force. Not reviewed: four upstream hash-only files, composer/skill implementation, live execution, hashes.

R1 judgments stay historical: this auditor ACCEPT WITH LIMITS (missed Claude B1 and the cache bypass). R2 is a new candidate.

Verdict: ACCEPT WITH LIMITS

R2 closes the two reproduced defects without a new false-accept in the stated dialect. No production, publication, or host authority is granted.

Closure of original defects

B1 (conflicting same-coordinate captures). Snapshot walk now keys

(kind, scheme, version) for releases and (kind, id, revision|version) for assignment/profile/crosswalk, and requires encode(payload) identity. Distinct capture envelopes with equal payloads remain allowed. The Claude counterexample—two complete scheme/version captures, one retired/nonselectable A vs active A, then a 1:1 approved mapping—now raises Invalid / Conflicting source payloads for one coordinate before candidate selection. Same rule covers profile meaning, assignment state, and crosswalk completeness (test_other_same_coordinate_payload_conflicts_are_rejected as written). This is packet-internal consistency only, not source authentication.

Cached ancestry bypass. R1 returned a compiled node after only len(stack)<8. Because _assess compiles baseProfile first, a 9-profile chain (base=chain[-2], target=chain[-1]) cached an 8-deep ancestor and accepted the ninth. R2 adds len(stack)+len(cached['ancestry'])<=8. Written bound: 8 conforms, 9 Invalid / deep profile ancestry. Uncached linear walk still refuses the 9th via len(stack)<8.

min>32. Schema still allows min≤256; runtime sets ready=False and PROFILE-CAPACITY / unsupported when min>32, including profile-only. Written: 32 conforms, 33 unsupported. max>32 alone is still usable.

Also present and aligned with the revised spec: duplicate selected crosswalk IDs refused; selected predecessor with a captured correction emits SOURCE-REVISION-CONTEXT notice without changing host selection; proposed emits PROPOSED-ASSIGNMENT notice and cannot become a migration candidate; concept interval miss is outside-valid-time on assignment detail; review() schema-checks the assessment and combined {packet,assessment} (1MiB encode) before return, so a fitting packet can still be refused if the full replay value would overflow—no truncation.

Regressions / new blockers

None identified in the delta. Unchanged fixtures still match the three example dispositions. effects remains []. Chain-request and metamodel-migration still refuse. inspect_snapshot still replays and returns authorized=false. Native IDs still derive from the assessment, not the classified subject. validate_native_fact still does not validate a separate object record (now stated in bindings/native-v3.md).

Nonblocking
validate_selection(..., new=True) is still unused; new-use activity remains the migration eligibility path.
Eligibility strings stay coarse (not-allowed / inactive-or-not-selectable).
Notices do not change the top-level fold (conforms-to-local-profile can still accompany proposed-state or a captured successor).
inspect_snapshot / native_records remain callable without review()’s live grant (documented trusted caller).
Schema min/max 256 vs runtime min>32 overlay is intentional, not a silent pass.
Limits

Static delta audit only. Author reports of 60 tests and 3 synthetic native Dimensions were not re-executed; digests were not recomputed. Excluded toolchain bytes unseen. Completeness, sourceDigest, and host approvals remain custody declarations. Same deferred surface as R1: no IAM, live assignment, reasoner, existing-Dimension migration, or standards certification.
