All four findings reproduced before fixing. rev-code-01 was right on each.
B2 (blocker, mine). SEAT-IDENTITY provisioning step 4 said to symlink the
framework store entry to the seat slot, while the same file says those bridges
must not be recreated. The same bridge, told both ways, in one document. I
rewrote the resolution and token-location sections when the deploy made them
stale and did not carry the change into the numbered steps. Step 4 is gone and
the file now says explicitly that no provisioning step links the store to the
slot, so the omission cannot read as an oversight.
S1 (mine). The guide claimed the helper "attempts a fleet notification" on
refusal. The shipped helper does no such thing — its only reference to
notification is a comment saying an alert built on the record is best-effort, and
there is no send or wake call anywhere in the file. Now: it writes a durable
record, the record is what exists, and nobody should wait for a notification that
nothing sends. A guide that promises an alert is worse than one that promises
nothing.
S2. Estate-local content removed from files that ship to every estate: the
~/.mosaic/fleet/bin script paths (dead paths elsewhere) and the 2026-08-18 dates,
which dated a specific host's migration rather than describing behavior. The
bridge-removal passage now states the ORDERING that matters — remove bridges only
after a seat-aware helper can reach the slot, never before — which is the part
that transfers.
B1. prettier reformatted all three files. Reproduced the pipeline 2515 failure
locally before and confirmed clean after; the other three guides prettier flags
are untouched by this branch (0 changes vs origin/next) and are pre-existing.
Sanitization gate re-run and passing.
Verified for the record, since I could not verify my own work: rev-code-01
confirmed the no-fallback claim TRUE against helper content on origin/next, and
judged the evidence rules actionable on the grounds that each names an executable
replacement.
Pipeline 2514 failed the sanitization gate on 'Jason mints the token into the
seat slot'. The denylist is jarvis|jason|woltje|... and a shipped framework file
must not carry operator identity. My mistake: I generalized the estate paths and
seat names when promoting this guide and did not check the operator name.
Now reads 'the estate operator', with the accompanying rule that an agent does
not ask another agent to mint one either.
Verified by running tools/quality/scripts/verify-sanitized.sh locally rather than
guessing at the pattern: gate passes.
Three guides that existed only as one host's working copy, promoted to framework
templates so every estate gets them. A working copy under ~/.mosaic binds one
host; only a template here binds all of them.
SEAT-IDENTITY.md (new) documents how a seat's git credential is actually
resolved after #1311: identity from MOSAIC_GIT_IDENTITY, then
mosaic.gitIdentity, then the stdin username; host mapped to a store prefix; then
ONE of two stores chosen by whether the seat directory exists, with no
precedence and no fallback between them. A seat with a directory and an empty
slot fails closed rather than reaching the service store, and that is the point.
It also corrects how to find the helper. credential.helper commonly names an
absolute path, so `command -v git-credential-mosaic` answers a different question
than the one git asks, and the two stop agreeing the moment the PATH copy is
removed. Git also tries EVERY configured helper in order, so a fail-closed helper
in front silently hands the request to whatever is configured behind it. The
guide says to read the whole list.
FLEET-COMMS.md (new) documents agent-send.sh: the class table, the addressing
preamble, and the exit codes — including that rc=2 means the text reached the
pane as an unsubmitted draft, so retrying double-sends it. Confirm with
capture-pane instead. It also says to measure the fleet rather than trust
roster.yaml, which on a live host was simultaneously naming a socket that did not
exist, listing seats that were not running, and omitting seats that were.
CODE-REVIEW.md gains an Evidence Discipline section: a green is not a result
until you have shown it could go red, measurement and explanation are separate
sentences, verify by content on the ref that ships rather than by ancestry of a
local sha, and confidence is part of a finding. Plus four shell-measurement rules
earned on #1311, each of which produced a wrong conclusion first — `cmd | tail;
echo rc=$?` reports tail's status, a missed glob under pipefail exits 2 and kills
the run under set -e, nonzero-with-no-output is an environment question before it
is a code question, and `git -C` in a non-repo directory answers from the
enclosing repo.
The estate-specific repository exception that lived in the working copy is not
carried here. The template says an estate may document one, scoped to a named
repository and never precedent for a second.
Both new guides are added to the two routing tables that agents read.
