Resumes the backlog sweep at a chunk size that actually gets read. Six auditors, 84 files
each, and all six read their full scope case-by-case against production — the first wave
where every chunk closed with no gap. 33 case declarations removed across 22 files, 1 test
file deleted, 826 lines gone. No production code touched.
This wave exists because a conclusion of mine was wrong. I had recorded that yield collapsed
~36x and that deletion was no longer the high-value work. I was dividing cases removed by
files IN SCOPE while the fraction auditors actually READ fell from 100% to about 4%, because
I kept handing them 300-800 files. Recomputed against files read, yield has been flat at 4-7
per 100 with no downward trend. This wave came in at 8.2.
The most instructive removal looked like the most valuable test in scope.
`orchestration-worker-release-reap-fixed.func.test.ts` cites a production bug by two
identifiers, describes orphaned PTYs accumulating until `TasksMax=4096` aborts processes on
EAGAIN, and advertises itself as the functional tier wiring the real orchestration RPC
surface, the real `OrchestrationDb` and the real release modules. Deleting it leaves no
reference to that bug anywhere in `src`.
It still had to go: its fake runtime performed the fence it asserted —
if (pty.incarnationId !== inc) { return null }
handleTable.set('term_reminted', { ptyId, epoch: rendererGraphEpoch })
— so the case checking that a reused ptyId with a mismatched incarnation does not resolve was
checking a decision its own spy made twenty lines earlier. The real fence is owned by
`orca-runtime-terminal-handle-incarnation.test.ts:257`, and the other two cases replay
`orchestration-worker-release-incarnation-fallback.test.ts` (which uses a plain
`mockReturnValue` rather than reimplementing the remint) and `worker/worker-release.test.ts:23`.
"Integration test" and "wires real modules" describe the scaffolding, not the asserted step.
Other removals: a self-comparison disguised by an alias, where
`export const getIssueOwnerRepo = getOwnerRepo` makes a case asserting the two "agree" into
`f(x) === f(x)`; four cases whose `vi.mock` of `resolveIssueSource` made both the preference
value and the topology inert; five verdict-precedence cases owned by a verdict-agnostic block;
three call-shape probes on one-line store pass-throughs whose real contracts are driven by
behavioural neighbours; and a `export type _Ref = [...]` declaration whose own comment admits
it exists only to preserve test-only module-surface references.
Kept after checking production rather than shape. An auditor found two near-identical
ten-reconnect loops and kept both: one uses a test-local live-lease filter, the other the
shipped `sshRemotePtyLeaseAllowsReattach` predicate, and the file's own comment explains the
duality is deliberate "so the two cannot drift". Another kept a paths-alignment case that
looks like a validator tested against its own list, because adding a generated file without
registering its path does fail it — and `shellReadyWrappersExist` uses that registered list to
decide whether a partial tree needs regeneration.
Production duplication is now confirmed four times over, and it is why mirrored tests exist:
`createUpdateWorktreeLineage`/`createAssignWorktreeParent` differ by one `console.error`
string; `terminal-path-tap.ts` and `document/path-tap.ts` carry hand-maintained copies of
`matchFilePathAtColumn` under a docblock reading "keep the two in sync". In those cases both
test sides are load-bearing and the duplication belongs on a refactor list.
`mobile/tests-typecheck-baseline.txt` loses one entry. Trimming
`relay-host-signed-out-verdict.test.ts` made it typecheck clean, so the ratchet required
pruning its grandfathered entry — the file graduates from exempt to enforced. Baseline is now
124 entries, down from 125.
Verified: 690 test files / 7,560 cases pass across the touched desktop areas; the modified
mobile files pass (162 cases); `check-tests-typecheck-ratchet.mjs` OK (898 files in program,
124 grandfathered); `check-reliability-gates.mjs` 140 gates; the deleted file is absent from
the gate manifest, `cloud/package.json` and the mobile baseline; nothing under
`mobile/src/test-support/rpc-recording/` or `mobile/rpc-foundation/goldens/` touched.
