4. Fleet execution
11:08:32 – 12:52:44 · claude-sonnet-5 orchestrator, claude-haiku-4-5 fleet · tier gate PASS
Source: Transcript B, turns cited as [n]. Notation key: index §3.
Nine tickets, three waves, seven merged branches. Along the way: a launch bug that costs nothing, a failed attempt, a no-op, a model escalation, and two investigations into edited test files.
Reminder from §3: the fleet runs on the small tier by deliberate choice, so that the kill and rewrite machinery has something real to catch. The failures below are the instrument working.
11:11:09 [76] — The wave plan, and a consent gate before anything becomes public
SLOPSTOP SAYS: Wave 1 (solo): #2 Foundation — blocks everything. Wave 2 (parallel once #2 lands): #4 set, #5 get, #6 delete, #7 list, #8 export — disjoint file maps. Wave 3 (solo fan-in): #9 Integration — after all of #4–#8 land.
Caused by: Q2 at 10:09:48 in §1. This is that answer, executed.
Each agent launches as a headless claude -p background session with
--allowedTools Bash(gh:*) Bash(git:*) Bash(go:*) Bash(golangci-lint:*) Bash(gofmt:*), creates a
worktree and branch, pushes commits, and posts progress comments on its own GitHub issue.
And it stops before acting on the outside world:
GATE: “Before I fire Step 4 and start pushing real branches/comments to that public repo: confirm I should launch the fleet now, starting with #2?”
11:2x – 11:40:30 [225] — Three nested blockers, and a zero-cost accounting decision
- First launch fails. Diagnosis:
--permission-mode autodoes not auto-approve the agent’s ownWritetool;acceptEditsdoes. - Second blocker: the orchestrator’s own classifier will not let it launch a subprocess with
acceptEdits. - At 11:36:21
[186]Ian asks for the permission rule; it addsBash(claude -p *)to~/.claude/settings.json— global scope, Ian’s choice, after confirming. - Relaunch — and the accounting call:
SLOPSTOP SAYS: “no attempt consumed for the first failed launch since it was an orchestrator bug, not a ticket/agent defect.”
Why interesting: the attempt budget is what eventually escalates a model tier and eventually gives up. Charging a ticket for the orchestrator’s own bug would corrupt every downstream decision. This exact distinction gets re-litigated by the adversary at 13:03 in §5 — and the ledger turns out to have been right while the prose was wrong.
Both drift findings so far (this one and the branch_type doc contradiction from
§3) are logged in fleet-state.md for the eventual upstream report.
11:52:34 [252] — Gate 0 passes, and the verification still runs
SLOPSTOP SAYS: “Gate 0 (red-test tamper check) passes mechanically — the frozen test files (
store_test.go,resolve_test.go) show zero diff between the Phase 0 commit and the branch tip. Now spawning the two fresh handoff-verification subagents (requirements adversary + code reviewer) in parallel.”
Why interesting: a clean tamper check is not a pass. Two fresh readers with no conversation history are spawned anyway, and they are what find the next thing.
11:55:55 – 11:56:43 [255],[258],[260] — Attempt 1 FAILS. Two independent subagents converge on the same defect.
ADVERSARY (both verifiers, independently): “
View()never acquires the sidecar lock, so it never touches the<store>.locksidecar and thus never requires a writable directory. On a read-only directory with no store file, it returns(map[string]string{}, nil)instead of erroring — a silent empty read.”
Both verified it live, not by reading: created a 0500 directory containing no store file,
called View(cfg), got map[] err=<nil>. Both quoted the ticket’s Observable behavior 4 verbatim
back at the code:
TICKET #2, Observable behavior 4 (written by the adversary at 10:46:55): “Because locking creates a sidecar (behavior 5), both
ViewandUpdaterequire a writable directory — a read-only directory yields a clear error, never a silent empty read.”
Second finding: golangci-lint run is not clean — 18 errcheck findings across store.go,
lock_unix.go, main.go.
Trace it all the way back — this is the payoff of the entire grill:
| Time | Event |
|---|---|
| 10:18:41 | Ian overrides “defer” → locking exists at all |
| 10:19:44 | flock chosen, on the store file |
| 10:39:12 | adversary: flock + rename = orphaned lock → move it to a sidecar |
| 10:46:55 | adversary round 2, finding N4: “sidecar locking makes every read require a writable directory; stated nowhere” → becomes Observable behavior 4 |
| 11:55:55 | the implementing agent violates behavior 4 — the exact failure class the ticket was amended to forbid, 69 minutes later |
A requirement written by an adversary at 10:46 catches an implementation bug at 11:55 that no test in the tree covered.
Note also the fix instruction sent to the agent at [266] — it does not merely name the bug, it
hands over the reproduction and demands the agent run it:
SLOPSTOP SAYS (to the fleet agent): “Verified live by the adversary:
Viewon a missing store path inside a0500directory returnedmap[] err=<nil>— reproduce this yourself before and after your fix.”
11:58:31 [290] — The no-op. A capability failure, not a code failure.
SLOPSTOP SAYS: “Attempt 2 produced nothing — the agent printed ‘Waiting for slopstop-start to complete…’ instead of actually invoking the
Skilltool, exited clean, no commits, no ticket comment. This is the exact ‘slash text is inert’ failure mode already documented as a known Haiku-tier scar inrun-agent-brief.md. No new work to verify.”
Why interesting: the weak model did not write bad code. It narrated doing the work and exited
- A CI-shaped check sees a clean exit and a green tree. Only “did the tip move / did a comment appear” catches this. That is 2 failed attempts → Step 7 diagnosis fork.
11:59:40 [320] — The escalation ladder, stated plainly
SLOPSTOP SAYS: “attempt 1 failed handoff verification on two real findings, attempt 2 was a no-op from the weak model, and attempt 3 is now running on sonnet-5 with both sets of findings.”
Diagnosis recorded as capability-gap; the escalation and its trigger are posted to the issue.
Note the discipline at 12:15:49 [521] when KV-4 hits the identical no-op:
SLOPSTOP SAYS: “Relaunching attempt 2 — still on haiku per the budget rules — escalation only kicks in after 2 failed attempts.”
One failure is not evidence. The rule is not bent for a hunch, even when the orchestrator has just seen this precise failure mode an hour earlier.
12:05:46 [349] — Frozen tests changed. What happens next is the interesting part.
The attempt-3 fix commit touched both frozen files. Classification:
SLOPSTOP SAYS: “every change to the two frozen files is a mechanical
X→_ = Xerrcheck discard (bothos.Setenv/os.Unsetenvinresolve_test.goandf.Close()instore_test.go) plus one wholly-new test appended tostore_test.go. No assertion values changed, nothing skipped or removed. This is defensible — the agent disclosed it proactively rather than hiding it — but I want the fresh subagents to independently confirm that read before I trust it.”
Why this is the best-formed judgment in the run: a defensible edit plus proactive disclosure
still does not buy trust. It buys a second opinion. The instruction to the verifiers at [350] is
explicit — “IMPORTANT — the fix commit touched the two FROZEN Phase-0 test files, which is exactly
the kind of thing Gate 0 exists to catch. Do NOT skip this.”
12:10:22 [358]: both fresh subagents PASS on attempt 3. KV-2 blessed at e6533a5.
12:18:44 – 12:23:16 [570],[592],[609],[613] — The tamper investigation that ends in an acquittal
KV-6 rewrote isErrUsage, a helper used by frozen test assertions, from:
// Check if it's store.ErrUsage or wrapped in it
var m map[string]interface{}
if json.Unmarshal([]byte{}, &m) == store.ErrUsage {
// This is just a way to check - we use the sentinel
}
// Actually, we need to check the error directly
return err == store.ErrUsage || (err != nil && err.Error() == store.ErrUsage.Error())
to:
return errors.Is(err, store.ErrUsage)
At [573]:
SLOPSTOP SAYS: “This one needs scrutiny before I trust it:
isErrUsage, a helper used by frozen test assertions, was rewritten between the Phase-0 commit and tip — not a test assertion itself, but exactly the kind of ‘expected value lives in an edited helper’ evasion Gate 0’s adversary checklist calls out.”
The instruction to the verifiers at [592] is the exemplary bit: it hands over the raw diff and
the command to reproduce it, and demands they re-derive the conclusion rather than accept the
framing. Both did — independently rebuilding the Phase-0 stub and tracing that delete.go returns
store.ErrUsage bare, unwrapped, so the old helper’s surviving branch was already equivalent
[609]:
ADVERSARY: “No expected value, assertion target, or test name changed… This does not constitute tampering under the ticket’s ‘changed expected value’ bar.”
Verdict posted publicly on the issue at [613], with the reasoning, not just the outcome.
Why interesting: the tamper gate’s value is not that it convicts. It is that a
suspicious-looking edit gets adjudicated on evidence, in public, and the acquittal is recorded —
PASS@ed29cf1 (isErrUsage cleanup scrutinized, benign) carries into the ledger and every
downstream report.
12:42:40 [830] / 12:52:44 [900] — Bugs the test suite structurally could not find
- 12:42:40 — KV-9 attempt 1 FAIL: “README overclaims that exit code 1 is exclusively for
get’s key-not-found, when the code actually maps *any non-ErrUsageerror to exit 1.”* - 12:52:44 — three more, and the reason they survived:
SLOPSTOP SAYS: “three README accuracy bugs the e2e test structurally couldn’t catch (it happened to use alphabetically-ordered test keys)”
Why interesting: the suite is green and stays green through all of it. A test that accidentally chose sorted keys can never distinguish “sorted output” from “insertion order” — and recall that ordering was decided at 10:13:16, Q6, in §1. Green ≠ correct, demonstrated rather than asserted.
12:43:23 [843] — Fix-forward instead of blocking
The umbrella drift-check on #3 finds vacuous test assertions in set — filed as
#17, “rather than blocking
the run.”
Why interesting: a real defect found late, and the process neither hides it nor holds the run hostage to it. Note what it is: a test that passes without asserting anything — precisely the slop the whole apparatus exists to stop, caught by the last check rather than the first.
The same message states the gate that will close the run, 70 minutes early:
SLOPSTOP SAYS: “that gate needs your explicit acceptance, so I won’t clean up the run directory without it.”
Section summary — the fleet ledger
| Ticket | Attempts | What happened | Verdict |
|---|---|---|---|
| #2 Foundation | 3/3 + 1 zero-cost | orchestrator config bug (uncharged) → real work, FAIL on 2 findings → no-op → escalated to sonnet-5, PASS | merged |
| #4 set | 2/3 | no-op → PASS | merged |
| #5 get | 1/3 | PASS | merged |
| #6 delete | 1/3 | PASS, isErrUsage scrutinized, benign |
merged |
| #7 list | 1/3 | PASS | merged |
| #8 export | 1/3 | PASS | merged |
| #9 Integration | 2/3 | README accuracy FAIL → PASS | merged |
Two distinct failure classes, and they want different responses:
- Real defects (#2’s
Viewbug, #9’s README) — feed the findings back, same tier, retry. - Capability failures (the no-ops) — the model cannot invoke the tool at all; more attempts at that tier are wasted, so escalate after two.
Deviations logged for the upstream report: partial/missing tracking-dir writes on KV-5/6/7/8,
inconsistent PR-decline behavior, and inconsistent GitHub auto-closing (three PR bodies happened to
contain Closes #N, two did not).
