feat: ratify independent-gold invariant (INV-25) + SHA-pin deductive lane
INV-25 makes the GSM8K lesson structural: no capability claim is valid unless its gold is computed by a procedure sharing no code with the system under test. Three meaningfully-failing checks (proven able to fail): 25a oracle imports no SUT module (AST); 25b every committed deductive gold is reproduced by the independent oracle AND matched by the engine; 25c an unsound engine disagrees on committed cases. SHA-pin the deductive lane (deductive_logic_v1, dev+holdout+external 716/716, wrong=0, refused=0) via a deterministic --report writer + run_as_module (the lane dir's local generate.py shadows the package in script mode) + CLAIMS regen. Fix drift the review surfaced: contract.md + pivot doc claimed an 8,000/7,340 fuzz and an 'external mirror' -> corrected to the real gated 3,000-case fuzz (2,796 definite) and 'hand-authored, NOT a published-benchmark mirror'; pivot doc GSM8K holdout 0->5 (all 5 are R1 reconstruction; composer scored 0). Validated: smoke 78, deductive 23, proof 29, invariants 44, lane-sha+claims 9.

# INV-25 Independent gold — a promotable-capability lane scores against an
|
||||
# oracle that shares NO code with the system under test (SUT)
|
||||
# ===========================================================================
|
||||
#
|
||||
# Claim (the GSM8K post-mortem made structural, docs/analysis/
|
||||
# pivot-to-deductive-logic-2026-06-04.md §"the GSM8K lesson"):
|
||||
#
|
||||
# No capability claim is valid unless the gold it is measured against is
|
||||
# computed by a procedure INDEPENDENT of the engine that produced the
|
||||
# answer. A "gold" that shares code with the engine only proves the engine
|
||||
# agrees with itself — exactly the blind spot that let the GSM8K composer
|
||||
# serve 87 wrong held-out answers it could not tell from its 2 right ones.
|
||||
#
|
||||
# The deductive-logic lane is the first lane to earn a real correct number
|
||||
# (holdout 500/500, wrong=0), and it earns it honestly because its gold is an
|
||||
# independent truth-table oracle (evals/deductive_logic/oracle.py): a separate
|
||||
# tokenizer + recursive-descent parser + brute-force 2^k model enumeration
|
||||
# that imports NONE of the ROBDD engine under test. This invariant ratifies
|
||||
# that independence as a structural, meaningfully-failing property:
|
||||
#
|
||||
# 25a (structural). Each registered oracle module imports none of its SUT's
|
||||
# modules. Fails the moment an oracle is "simplified" to reuse the
|
||||
# engine — the single change that would turn independent gold into
|
||||
# self-agreement.
|
||||
# 25b (behavioral). Every committed deductive case's gold is reproduced by
|
||||
# the independent oracle AND matched by the engine: engine == oracle ==
|
||||
# committed gold. This is the anti-overfit firewall — it fails if any
|
||||
# committed gold were ever engine-derived and diverged from the oracle.
|
||||
# 25c (non-vacuity). An unsound engine (entailed<->refuted flipped) is shown
|
||||
# to disagree with the oracle on committed cases, proving 25b can fail.
|
||||
#
|
||||
# A new lane that claims a promotable/checkable capability MUST register its
|
||||
# (oracle, SUT) pair here. The CI failure is the prompt to do so.
