ACCEPTANCE 5, and it needed a real test rather than a weakened claim.
`listview_acceptance` says in its own header that the references panel
"needs a live LSP and is validated manually / via the m4 harness", so it
does not exercise `*references*` at all; the m4 hover test asserts
content PRESENCE, not exact output. Neither would notice a flat consumer
silently gaining an indent column — the regression a tree extension can
introduce. So the coverage is written against the real entry points
through the fake language server.
`*references*` is pinned EXACTLY: the row is the location string and
nothing else. `*lsp*` formats its own two-space indentation, so
"starts with a space" is not a violation there; what must hold is that
the primitive reproduces the consumer's text verbatim, matched as a
WHOLE LINE — a substring would still be found inside a further-indented
copy of itself. Volatile parts (pid, elapsed) are deliberately excluded,
the same normalization reasoning the CI registry uses.
THE FIRST BITE PASSED, AND THAT WAS THE FINDING. Injecting
`string.rep(" ", row.depth or 0)` did not fail the test — flat rows
carry no depth, so it added nothing. I had simulated a regression the
flat path is immune to and would have recorded the test as verified.
The regression this criterion actually guards is an UNCONDITIONAL
column, a fold gutter on every row; with that injected the test fails on
"the flat references row renders verbatim". A bite that passes validates
the pair, not the test — and injecting the wrong defect teaches nothing
while feeling like assurance.
A VERIFICATION RECORD, including one unclassified occurrence. The first
local crdt sweep of this branch reported 7 failures and its SIGNATURES
WERE DESTROYED before being read, piped through an aggregation that
emitted only totals. That is the failure the CI registry exists to
prevent, committed one lane after writing it, and it is why the cause
cannot now be established rather than merely being unknown.
It is recorded in this lane's own framing and deliberately NOT as a
registry row: that registry keys on a normalized signature, and an
occurrence with none would be granted a recognisability it cannot
support — the same reasoning that made the unevidenced incumbents audit
notes rather than rows.
Four re-runs are tabulated with what each supports. Two were not
isolated, including one where my own guard printed "aborting" and did
not abort. TWO GENUINELY ISOLATED RUNS ARE BOTH CLEAN, which supports
repeatability under isolation and establishes nothing about the cause.
Two mechanisms are recorded as NON-CAUSAL hypotheses, because both were
present and neither can now be tested: a shared CARGO_TARGET_DIR (whose
reciprocal case another lane observed independently, with `pgrep`
evidence and failing text that named its own cause), and ~40 resident
leaked daemons. Having two plausible mechanisms and no way to
discriminate IS the result; naming either would repeat the reasoning
this project has rejected — concluding something about an occurrence
from something that was not about that occurrence.
Both mechanisms are recorded as standing hazards in the handoff, and the
daemon leak gets its own candidate lane: 42 orphans, oldest four days,
reparented to systemd with deleted sockets, from
`gpu_invocation_acceptance`'s one-command tests, leaking 3-4 per sweep
as measured rather than estimated. It predates this work and belongs to
the reap-ledger family — a process outliving its supervisor with nothing
watching it — but the existing ledger arms only for `spec.group` and so
does not cover it.
Verified: fmt, diff-check, luajit sweep 3453/0 and crdt 3722/0, each
exactly +4 on its baseline.
