Independent review of cae1d32 returned two blocking findings and one stale
rationale. Both blocking findings are in requirements revision D itself wrote,
and both are revision D's own closing lesson turned back on it.
1. Row 8's new generator test had no name, so nothing consumed it. Gate 6
named only m41 and m41b; §6 item 2d asks for shrink evidence. Omitting the
test entirely would still compile, satisfy all four all() loops, and pass
every named gate.
Named invariant_21_negative_generator_breaks_staff_to_group_only, with its
three assertions spelled out: exactly one violation and it is
StaffGroupMembershipAgreement, the witness naming the S->G ids, and the
G->S direction asserted satisfied. Added to gate 6 and to new §6 item 2e.
This is revision D's own lesson unapplied to itself: it closed by
distinguishing a rule with no consumer from a rule with no observer, then
wrote a requirement with neither. An unnamed artifact cannot be gated,
because every gate here names what it checks.
2. Gate 6 demanded runtime evidence the prescribed tests cannot emit. It said
to quote check_invariants' full return and witness ids, but these are
assert!-style tests in m40's shape and cargo test prints ok, not local
values. Obeying it literally would need unpinned --nocapture
instrumentation added purely to produce a report, or source inference
presented as observation.
Evidence model now chosen explicitly: quote the SOURCE assertions plus the
pass verdict. A passing exact-set assertion IS the observation -- the
assertion text says what was checked, the verdict says it held. This
follows S27's gate 6c, which quotes a struct definition rather than
grepping for it: a quoted source construct is read, not inferred. It also
adds no code to epiphany-core written solely for a report.
The requirement was right and the mechanism was borrowed from gates that
run commands and read stdout. A gate must name evidence the prescribed
artifact actually produces; otherwise execution improvises, and improvised
instrumentation is unpinned scope arriving through the report.
3. Gate 4's rationale still said row 11 is "conditional," which revision D
changed to decided-unused. A fourth site under pin 10a said "carrying it
conditionally costs nothing" -- found by sweep. Both updated. The subset
rule itself is unaffected; only its rationale needed the current term.
Still DRAFT, still unratified. No implementation work has begun.
