Review finding (P2): docs/active-work.md and docs/agent-handoff.md both
still said "PR not yet open". This file's own rule is that an open PR
gets a lane recording its state — "When a PR is opened, give it a lane",
written after #171 drifted 153 commits while invisible here. Both now
carry PR #209, its six commits, and the first CI run.
That run is worth recording rather than merely citing, because it
discharges the one risk the framing could not close locally. ALL 14
CHECKS GREEN, including both new jobs (Test (crdt) 12m20s, M10 Perf
Gates (crdt) 5m40s) and the macOS/luajit leg that is the documented
flake surface. This was the first time in the project's history that
any of these tests executed in CI.
ACCEPTANCE 8 HOLDS AGAINST THE REAL RUN. Test (crdt) reported 3,717
passed / 0 failed / 30 ignored: the 3,746 all-targets census (with
basedpyright NOT skipped, as it is locally) plus one doc test, less the
30 ignored. The job demonstrably compiled and ran the crdt corpus rather
than reporting green over nothing — which was the whole point of writing
that criterion while the local sweep was already green.
A trap for the next reader is recorded with it: DO NOT SUBTRACT THE TWO
JOBS' TOTALS. Test (ubuntu/luajit) reports 3,485 and Test (crdt) 3,747,
a difference of 262 rather than 279, because the jobs run different
SETS — the non-crdt job adds pmacs-protocol's 17 tests. The dark count
is the all-targets comparison, 3,746 - 3,467. The wrong number looks
entirely plausible.
Chasing that discrepancy found a real gap, and one this lane's own tool
could never have surfaced: PMACS-PROTOCOL HAS ITS OWN `crdt` FEATURE.
It gates no tests, so a per-test census reports 17 either way and scores
the crate as unaffected — but it changes `cfg!(feature = "crdt")`
EXPRESSIONS inside InstanceCapabilities::default and
FrontendCapabilities::default, so those same 17 tests exercise different
runtime values under it. CI had only ever run the non-crdt ones. Closed
with an explicit `-p pmacs-protocol --all-targets --features crdt` step,
verified 17/17.
The blind spot is structural, not an omission, so it is documented at
the tool rather than fixed in it: scripts/feature-census censuses the
workspace DEFAULT MEMBER, because that is what a bare
`cargo test --all-targets` builds. Sibling crates are invisible to it no
matter what configs are passed. The durable lesson: A FEATURE CAN MATTER
TO A CRATE A PER-TEST CENSUS SCORES AS UNAFFECTED. Check siblings by
hand.
Verified: ci.yml parses at 10 jobs, script syntax clean, fmt,
diff-check, and the new protocol step green locally.
