Closes the CMB ladder with a docs-only lockfile. No behavior change.
- New docs/analysis/combined-rate-capability-ledger-2026-06-08.md: the frozen
R4 v1 claim, supported solved grid, solver/reader boundaries, the three
proposal-allowed deferrals, router/contemplation integration, the
domain-precedence adjudication (named, with proof cases cmb-11/15/12·13·14),
a prominent non-claims list, and the verification lanes. Every cited number
re-confirmed against the lanes: gold 19/19 (6/5/8), solver 6/0/5, reader
11/0/8 -> answers 6/0/13; the 7 R4 test files 93 passed.
- Updates comprehension-organ-capability-ledger-2026-06-08.md to fold R4 in as a
fourth organ: organ block, 4-organ router + cmb_* namespacing, a named
domain-precedence section, R4 lane rows, and a reframed deferred/next that
points the next frontier at served-surface epistemology (not more comprehension).
Honest accounting: 1 pre-existing red (test_findings_reset_between_turns) is red
on clean origin/main and imports nothing from R4 — unrelated.
Off-serving unchanged (sealed); no generate.derivation / core.reliability_gate.
Consolidation/true-up after #646-#648. Records the off-serving comprehension
system as one ledger: R1 relational arithmetic, R2 finite-integer constraints,
R3 explicit single-rate + exact minute/hour conversion, the router/contemplation/
proposal loop, the proposal-review reporter, idle_tick read-only visibility, and
the standing router-organ-hygiene invariant. Pins the whole-system lane state
(answer_wrong==0 everywhere) and the off-serving import-disjointness guarantee.
Also fixes a documentation-integrity defect the R2 batch introduced: the R2 ADR
took number 0211, which collided with ADR-0211 (Conformal Falsification Bench,
2026-06-06 — earlier, test-pinned, depended on by ADR-0216). The conformal ADR
keeps 0211; the R2 ADR is renumbered to the next free number 0217. Ratified
decision content unchanged; only the identifier and references move.
