71542e61 fixed only half of H-13 and asserted a premise that is false. This
replaces it, and records why, because the failure mode is the one this arc
exists to catch.
WHAT WAS WRONG. The refcount rested on "seeding and eviction walk the same
source list, so the counts balance." They do not. The call site's arms are
MUTUALLY EXCLUSIVE (pipeline.py §10b): a proposal is seeded when SPECULATIVE or
released when COHERENT, never both. So a release never balances a claim the
same proposal made, and a COHERENT proposal ALWAYS releases claims it never
held. Refcounting therefore repaired only the sub-case where both proposals had
been taught speculatively. The ordinary case — an unreviewed `wisdom`, then a
separate correction about `practical wisdom` that passes review on its own turn
— still stripped the marker. Measured against the landed refcount:
`sibling marked? False`.
The first attempt's tests passed because their helpers split tokens themselves,
mirroring a call pattern production no longer used — tests written to the fix
instead of to the defect. That is the same "asserted past the evidence" failure
diagnosed in two external assessments earlier today, committed here one commit
later, and catchable by reading fifteen lines at the call site.
WHAT IS CORRECT. _speculative_subjects maps token -> SET OF CLAIMING SUBJECTS.
A token is evicted exactly when the subject that actually claimed it is
reviewed; discarding an absent claimant is a no-op, so a neighbour's marker
survives. Token derivation moved out of the call site into
_speculative_index_tokens, because ownership is what the call site cannot see —
doing the split out there made every token its own claimant, which was the bug.
Tests rewritten to call the cache exactly as §10b does. The lead pin
(test_coherent_proposal_does_not_unmark_an_unrelated_subject) was confirmed to
FAIL against the refcount design before this landed, so it discriminates rather
than merely passing. 13 pins green; the 8 pre-existing lifecycle pins unchanged.
SUITE MEMBERSHIP, resolved rather than deferred. The file pinning this behavior
sat in NO curated suite, reachable only through `full` — which is why the
regression was invisible (G-7's mechanism, on the pin that would have caught
it). Registered now in BOTH TEST_SUITES["smoke"] and smoke.yml, per the #136
precedent that an unregistered pin runs nowhere. Verified the local/CI delta is
unchanged at exactly ten files (local 24, CI 14, CI-only 0), so this is
compatible with all three R-14 options and settles none of them; PR-4 still
owns the standing ten.
Cleanup as found: three unambiguously dead imports removed from pipeline.py
(hashlib, RatificationOutcome, RatifiedIntent). ruff 4 -> 1; the survivor is a
pre-existing structural E402, left alone.
Ratification note unchanged: this changes served surfaces — markers appear on
turns where they previously vanished. Direction is toward disclosure and it
restores ADR-0021 §Articulation's stated intent rather than extending it.
