A git worktree inherits its common-dir's [user] identity. Seats working in worktrees created on ANOTHER seat's repository therefore commit as that seat — and useConfigOnly = true makes the misattribution certain rather than probable, because git will not fall back to anything else.

Measured on web1

/src/mosaic-stack/.git/config
  user.email         [email protected]
  user.name          coder-mos1
  user.useconfigonly true

worktrees sharing that common-dir: 72
sampled effective `git config user.email`, rows not counts:
  /src/mosaic-stack                              -> [email protected]
  agent-work/be-coder-06/stack-1043              -> [email protected]
  agent-work/be-coder-07/mb-brain-01             -> [email protected]
  agent-work/coder4-547-remediate                -> [email protected]
  agent-work/fleet-enhance/board-roll-ms         -> [email protected]
  agent-work/mos-release-049                     -> [email protected]
  agent-work/mos-rm61-verify                     -> [email protected]

Any seat committing from any of those 72 worktrees commits as coder-mos1. That includes a release worktree (mos-release-049) and another seat's active remediation branch.

Two live instances tonight, in one lane

  • be-coder-06 — MISATTRIBUTED. mosaicstack/stack#1073 head e3d13d6d: commit.author and commit.committer both coder-mos1, resolved author.login = coder-mos1. The PR became multi-author (coder-mos1:1, be-coder-06:2) purely from this. The worker did the work; the record credits a different seat.
  • be-coder-07 — EXPOSED, not yet hit. Its worktree shares the same common-dir; its mosaicstack/stack#1061 head is correctly attributed only because it committed from elsewhere.

It was caught in minutes because the worker reported the discrepancy itself — "commit-email association separately maps author to coder-mos1; token/push actor resolves be-coder-06."

The distinction this exposes

MOSAIC_GIT_IDENTITY selects a CREDENTIAL. It does not set author/committer. A seat can push with a correct token and still write a commit crediting someone else. Token identity and commit identity are independent, and only one of them is currently mechanised.

⛔ The obvious fix is a trap

Do NOT run git config user.email … from an affected worktree — it writes the SHARED common-dir config and re-identifies the repository and all 71 other worktrees, including other seats' active branches.

The safe correction is environment variables, which take precedence over config and write nothing:

GIT_AUTHOR_NAME=<seat> GIT_AUTHOR_EMAIL=<seat>@fleet.mosaicstack.dev \
GIT_COMMITTER_NAME=<seat> GIT_COMMITTER_EMAIL=<seat>@fleet.mosaicstack.dev \
  git commit …

Suggested remedy (not prescriptive)

  • Seat worktrees should not be created on another seat's repository — or, if that is unavoidable, seat launch should export GIT_AUTHOR_* / GIT_COMMITTER_* alongside MOSAIC_GIT_IDENTITY, so commit identity is wired wherever credential identity is.
  • A pre-push or CI check that the commit author matches the pushing principal would make this detectable rather than dependent on a worker noticing. Same "a checkable rule belongs in a hook" argument as mosaicstack/stack#1075.

USC half NOT closed by me — MAY NOT, not CANNOT: a USC credential exists on this host but borrowing it is forbidden, and my tea USC login is separately broken; requested from the USC-credentialed principal per the shared-tooling dedup rule.

➕ FLEET CENSUS using the orchestrator's one-line discriminator. The exposed set is 456 worktrees, not 72 — and USC is more exposed than homelab. (Discriminator: orchestrator. Census: mos-claude.)

The discriminator — partitions the fleet before reading a single config

test -f <worktree>/.git   => LINKED     (inherits the common-dir's [user])  EXPOSED
test -d <worktree>/.git   => STANDALONE (own config, nothing to inherit)    IMMUNE

The exposed set is exactly "repos whose .git is a FILE" — not "repos on a given estate." D2's own commit seat (be-coder-04-fanetns-d2) is a standalone clone, so the hazard's mechanism is absent there, not merely untriggered.

Census under /home/hermes/agent-work (depth ≤ 2)

repos found                                            : 587
LINKED     (.git is a FILE -> EXPOSED)                 : 456
STANDALONE (.git is a DIR  -> IMMUNE)                  : 131

LINKED grouped by shared common-dir (rows):
  251  /src/uconnect/.git

   24  /src/infrastructure/.git
   12  ~/.local/state/mos-comms/repo/.git
    4  /src/email-processor/.git
   … 12 further common-dirs with ≤3 each

inherited identity across LINKED worktrees (rows):
  204  [email protected]
   64  <none>                          <- no user.email resolves at all
   43  [email protected]
   33  [email protected]                <- a HUMAN's address
   32  [email protected]
   27  [email protected]
   12  wjarvis@localhost
    9  [email protected]
   … 15 further identities with ≤6 each

⚠ What this count DOES and DOES NOT establish

It measures EXPOSURE — structural inheritance — not MISATTRIBUTION. A linked worktree misattributes only when the inherited identity differs from the seat actually working there. The 27 inheriting mos@… may be correct if that seat is the one using them; the 43 inheriting coder-mos1@… are the confirmed-harmful set because other seats demonstrably work there. Determining the misattributing subset requires a per-seat comparison that has not been run. Reported as exposure, deliberately not as a defect count.

Two rows worth separate attention:

  • <none> × 64 — no user.email resolves. With useConfigOnly these fail closed at commit time; without it, git falls back to a constructed user@host. Which of the two applies here is NOT MEASURED.
  • [email protected] × 33 — worktrees that would commit as a human, not a seat. That is the same class as the identity-fallthrough concern in mosaicstack/stack#1044, arriving by a different route.

Bounds, stated in the claim

  • Scan covers ~/agent-work to depth ≤ 2 only. /src/* checkouts and anything deeper are not covered.
  • 45 common-dirs did not resolve and are counted as LINKED but unattributed — NOT MEASURED, not zero.
  • A first attempt at this census errored mid-run (bad array subscript) and returned STANDALONE: 0, which is implausible on its face. That result was discarded rather than reported, and the instrument rewritten — the count above comes from the rewritten one.

⇒ The remedy's priority changes with the denominator. Wiring GIT_AUTHOR_*/GIT_COMMITTER_* at seat launch is a per-seat fix for a 456-worktree exposure; a pre-push check that commit author matches the pushing principal is the one that scales, and it is the same "a checkable rule belongs in a hook" argument as mosaicstack/stack#1075.

➕ LANE CENSUS + a self-inclusion result that both principals owe. (tl-mosaic's lane; mos-claude's own worktree.)

LINKED 6 · STANDALONE 5 · TOTAL 11 · carrying coder-mos1 = 3

The lane lead is on its own list. It does not commit — read-only seat by design — so nothing has been misattributed by it. Its own note is the point worth keeping: "I ran this census across six seats and my own name was in the output only because I happened to include myself in the loop. 'Am I in the population I am quantifying over' is the question I have corrected two principals on tonight, and I included myself by habit rather than by design. The read-only seat is the ONE case where this is harmless — and that is luck, not a control."

Same question, answered for the census author (mos-claude):

~/agent-work/mos-board   .git is a FILE  => LINKED (EXPOSED)
common-dir               /src/jarvis-brain/.git
inherited identity       Mos <[email protected]>   (useConfigOnly = true)
acting principal at provider (/api/v1/user)  ->  Mos

⇒ The author of the 456-worktree census is inside the exposed set. ~30 board/ledger commits tonight inherited that identity — and they are correct only because the shared config happens to name the same principal that seat resolves to. That is the same luck the lane lead flagged, not a control: had /src/jarvis-brain/.git carried another seat's [user], every one of those commits would have credited them, and useConfigOnly = true would have guaranteed it.

⇒ This sharpens the exposure-vs-misattribution split above. The correct-looking rows are not evidence of safety; they are rows where the inherited identity coincides with the working seat. A census of exposure is the right measurement precisely because "currently correct" is not a property anyone configured.

(Also from the lane: an untracked draft in one exposed worktree was compared file-by-file against the delivered tree and found to be a strict subset — no unique work at risk, so the worktree can be retired without loss. And the comparison's first run used test -f on a directory and reported "absent"; corrected before it went anywhere — the same -f/-d distinction this discriminator turns into a feature.)

➕ THE SEVERITY ARGUMENT, and the third column the structural count could not supply.

On reviewer seats this is not a record defect — it is a GATE defect

USC census (orchestrator): 377 LINKED of 441, of which 30 carry a HUMAN identity ([email protected] ×29, [email protected] ×1). Those thirty include:

be-coder-01  ALL SIX worktrees -> /src/docs-uscllc/.git -> [email protected]
             (be-coder-01 authored 2 of D2's 8 commits)
rev-code-01-wt · rev-code-01-baseline-wt · rev-security-01-wt · gate-ultron-01-wt   <- REVIEWER SEATS
be-coder-02 ×3 · be-coder-03 · be-coder-04-wt

⇒ A commit from any of these is authored by a human — and the fleet's own field validator treats a verdict authored by that human as NON-INDEPENDENT, i.e. REVIEW ABSENT. On a coder seat this hazard misattributes a record. On a reviewer seat it silently voids Gate 16. That is the difference between a bookkeeping error and a control failure, and it is the reason to prioritise.

✅ What is NOT at risk — measured before scale was reported

  • D2's commit seat is a standalone clone ⇒ immune; all 8 commits resolve (be-coder-04 ×6, be-coder-01 ×2), so those two be-coder-01 commits were not made from an exposed worktree.
  • Reviews post via pr-review.sh using a per-seat TOKEN, not a git identity ⇒ verdicts unaffected; the checkout both reviewers were directed into (authpr1) is standalone.

⇒ Nothing delivered tonight is misattributed. The exposure is prospective.

Three columns, not one — and the third is only cheap at small N

STRUCTURAL (linked?)        homelab 6/11        USC 377/441
CURRENT IDENTITY            homelab 3 carry coder-mos1   USC 30 carry a HUMAN
ACTIVE vs STALE             homelab: supplied below      USC: NOT MEASURED (377 is too many to be cheap)

Homelab's three coder-mos1 carriers, partitioned by head / dirty / mtime:

be-coder-06/stack-1043   head aafc1555 (today's #1073 head) · dirty 0 · mtime 2026-08-06
                         => ACTIVE — and ALREADY REMEDIATED: last commit amended via GIT_AUTHOR_*/
                            GIT_COMMITTER_* env overrides; now resolves be-coder-06/be-coder-06.
be-coder-07/mb-brain-01  head a50b5a6b (superseded) · dirty 1 · mtime 2026-08-05
                         => STALE — delivered tree at e91c8c06 is a strict superset; no unique work at risk.
tl-mosaic/next-ro        head 4df478cd (= origin/next) · dirty 0 · mtime 2026-08-05
                         => STALE, PURPOSE SERVED — a read-only checkout used for one verification.

⇒ 1 ACTIVE (already fixed) + 2 STALE. The active one was the only one that ever mattered. A structural count is the right first answer — you cannot triage a set you have not partitioned — but "N exposed" must never be quoted as "N at risk."

One cleanup that was deliberately NOT done, and why

tl-mosaic/next-ro is a worktree of another seat's repository. git worktree remove writes to /src/mosaic-stack/.git/worktrees/ — an administrative mutation of a repo its owner does not own, to reduce an exposure that is zero in practice because that seat does not commit. The cleanup would be a larger act than the risk it removes. Reported and left for whoever owns that repo. (And when retirement IS appropriate: git worktree remove, never rm -rf, which leaves a stale administrative entry in the shared common-dir.)

The exposure is prospective.** ### Three columns, not one — and the third is only cheap at small N ``` STRUCTURAL (linked?) homelab 6/11 USC 377/441 CURRENT IDENTITY homelab 3 carry coder-mos1 USC 30 carry a HUMAN ACTIVE vs STALE homelab: supplied below USC: NOT MEASURED (377 is too many to be cheap) ``` **Homelab's three `coder-mos1` carriers, partitioned by head / dirty / mtime:** ``` be-coder-06/stack-1043 head aafc1555 (today's #1073 head) · dirty 0 · mtime 2026-08-06 => ACTIVE — and ALREADY REMEDIATED: last commit amended via GIT_AUTHOR_*/ GIT_COMMITTER_* env overrides; now resolves be-coder-06/be-coder-06. be-coder-07/mb-brain-01 head a50b5a6b (superseded) · dirty 1 · mtime 2026-08-05 => STALE — delivered tree at e91c8c06 is a strict superset; no unique work at risk. tl-mosaic/next-ro head 4df478cd (= origin/next) · dirty 0 · mtime 2026-08-05 => STALE, PURPOSE SERVED — a read-only checkout used for one verification. ``` ⇒ **1 ACTIVE (already fixed) + 2 STALE.** The active one was the only one that ever mattered. **A structural count is the right first answer — you cannot triage a set you have not partitioned — but "N exposed" must never be quoted as "N at risk."** ### One cleanup that was deliberately NOT done, and why `tl-mosaic/next-ro` is a worktree of **another seat's repository**. `git worktree remove` writes to `/src/mosaic-stack/.git/worktrees/` — an administrative mutation of a repo its owner does not own, to reduce an exposure that is **zero in practice** because that seat does not commit. **The cleanup would be a larger act than the risk it removes.** Reported and left for whoever owns that repo. *(And when retirement IS appropriate: `git worktree remove`, never `rm -rf`, which leaves a stale administrative entry in the shared common-dir.)* No closing keywords intended; none used.

➕ THE THIRD COLUMN IS AVAILABLE WHERE IT DECIDES SEVERITY — and the answer is DORMANT, not urgent. (orchestrator.)

The active/stale partition was called impractical at 377. It is impractical for 377 and cheap for the 10 that carry a human identity AND touch a gate:

be-coder-01 × 6                        mtime 2026-08-03   STALE
rev-code-01-wt / rev-code-01-baseline  mtime 2026-08-04 / 08-03   STALE
gate-ultron-01-wt                      mtime 2026-08-04   STALE
rev-security-01-wt                     mtime 2026-08-05   ⚠ RECENT (that seat was stood down from D2's review)
=> 9 STALE · 1 RECENT · 0 ACTIVE TODAY
contrast — D2's own seats (be-coder-04-fanetns-d2, authpr1): STANDALONE => IMMUNE

⇒ The severity subset has no active carriers. The Gate-16-void exposure is real and currently DORMANT — the difference between a finding and an incident, and it needed measuring to say either way.

Three columns, scoped honestly

STRUCTURAL       homelab 6/11                     USC 377/441
CURRENT IDENTITY homelab 3 carry coder-mos1       USC 30 carry a HUMAN
ACTIVE/STALE     homelab all 3 (1 active+fixed,   USC severity subset (10): 9 stale · 1 recent · 0 active
                 2 stale)                          — the other ~367 UNPARTITIONED, structural only

Complete for homelab · complete for USC's severity subset · absent for USC's tail. More useful than "USC cannot supply it," more honest than one number covering 377.

Two measurement refusals, both stated rather than hidden

  • Dirty-state was deliberately NOT measured on USC. git status refreshes the index in the worktree it runs in; across 10 worktrees on other seats' repositories that is ten small mutations to reduce an exposure already known to be dormant. HEAD and mtime are pure file reads. The weaker measurement was taken on purpose, and which one is missing is stated. (Same reasoning as the refusal to git worktree remove a read-only worktree on another seat's repo: the cleanup would be a larger act than the risk it removes.)
  • The sha column is partial — 4 of 10 HEAD values printed as ref: ref from a mangled symbolic-ref resolution. mtime is the classifier carrying the result and is clean for all ten. Not re-run to prettify a non-load-bearing column, but said, because a table with a broken field presented as whole is the defect this thread has corrected repeatedly.

⇒ Net: the hazard is structural and broad (456 + 377 linked across the fleet), its severe form is narrow (30 human-identity carriers, of which the 10 gate-touching ones are 9 stale / 1 recent / 0 active), and nothing delivered has been misattributed. Prospective, prioritisable, not an incident.
