Robert Allan JamesandClaude Sonnet 5 825ab078f1 POST coverage cluster 3/4: inference-engine accessors (proof-covered, previously untested) ...

New module (inference_words_test.c, Module 26) covers exactly the 8
words proof/COVERAGE.md marks proof-covered in inference_words.c (out
of 20 registered): the 5 output accessors (INFER-WINDOW@/DECAY@/
VARIANCE@/FIT@/EARLY-EXIT@), INFER-RUN (populates what they read), and
Q.VARIANCE/INFER-DECAY-SLOPE/INFER-WINDOW-WIDTH (array-based
primitives, using HERE as multi-cell scratch memory). Deliberately not
the L8 Jacquard or Bayesian-posterior words in the same file -- not
proof-covered, out of this cluster's scope.

Caught and fixed a contract-selection mistake before booting: copied
CONTRACT_PHYSICS_TRANSPARENT from the Q48.16 cluster without checking
whether it fit. It doesn't -- these words are specifically about
reading physics state (dictionary heat, rolling window), so asserting
A4' transparency on them would test an invariant they deliberately
don't have. Switched to CONTRACT_NONE with an explanatory comment.

Boot-verified: zero warnings, all 9 suite entries pass, FINAL TEST
SUMMARY 1031->1040 total / 993->1002 passed (+9 exactly), 0 failed,
contract checks (A4'/A1) still report "all passed" -- confirms the
CONTRACT_NONE fix actually avoided the violation, not just silenced it.

Cluster 4 of 4 (final one) left: physics freeze/diagnostic, 5 words.
Full writeup in FABRIC-2.md Section J.
