Filed ahead of execution so the contract is under version control before any
agent touches it. This session already learned the other way round: the G3b
contract sat untracked past a "clean" gate, because git diff --check cannot see
a file that never reached the index, which is why this contract's own section 5
mandates git diff --cached --check instead.
The rung it scopes is diagnostic. Invariant 20 has nine non-success paths, not
the three P13-S18 records; only three are abstentions. Two are delegated to
invariant 10, two are vacuous, one is inapplicable, one is P13-S19. The rung
builds an 18-cell outcome matrix, classifies every path, corrects the ledger and
two drifted citations in the G3b contract, and files P13-S23 for the capability
everything defers to. No behaviour change: the gate requires
check_measure_meter_consistency's executable body to stay byte-identical, and a
finding that suggests changing which graphs violate invariant 20 stops the rung
rather than being implemented in it.
Six review rounds are recorded in the pins as corrections, not smoothed away.
Successive drafts scoped the residue at five paths then nine; called the
Measure-end claim false, then misattributed, before landing on conditionally
false; conflated two distinct WallClock shapes whose clauses fail differently;
and scoped P13-S23 twice too narrowly, the second time excluding B5 -- comparable
pairs that yield no delta -- which is a third of what it is filed to own.
Baseline 1541/0 confirmed at f33673d. The commits since cc49533 are spikes/-only,
a separate workspace, so the root count is unmoved and the section 0 readings
stand.
