Two predicates over artifacts with a real grammar were each defeated by successive
spellings and withdrawn in favour of pinning the artifact whole: #887's shell parse
(nine defects from one mechanism, then seven more against a partial match of
web/vite.config.ts) and #891's lexical rule over the hook preamble (five spellings).
Both incidents carry a record; neither is resolvable by topic before round three, which
is what this class-level record adds.
Decides the two questions #901 left open:
- DEFAULT, not remedy. A shape-matcher's failure is a false GREEN, so the defeat that
would trigger a remedy policy is found by a reviewer or an incident and never by the
guard: "not defeated yet" measures who has looked. Rejected: write the matcher and
pin after the first defeat — it also understates its bill, since a withdrawal costs
the rounds spent AND the proofs calibrated against the narrow clause.
- The exception argument carries FOUR things: the grammar and its parser; the input
space as a closed enumeration with the reason it is closed; the fail direction
measured as a declared, executed mutation; and what it buys priced in a cost the pin
charges. Rejected: a numeric "survives N spellings" bar (measures the reviewer's
imagination) and a reviewer sign-off bar (depends on the signal that arrives late).
Records both riders (a pin assumes it pins the artifact that still DECIDES; widening a
clause turns a survived-clause canary into a tautology) and states the threshold as the
moment the NEXT spelling is found by the reviewer rather than the author.
docs/README.md's guard-convention task-signal row points at the record; catalog
regenerated; 59 prose lines, under the 60-line advisory ceiling.
