+# 150 — outcome: what shipped, what stayed open, what is still unverified
+
+Closing record for the 260819 unclaimed-bug unit. Five PRs on `dev`.
+
+| PR | dev | issue | disposition |
+|---|---|---|---|
+| #2116 | `bdaf4463a` | #2107 | **closed** — proxy env baked into service definitions |
+| #2117 | `c701cc7e6` | #1933 | open — decoding fixed, diagnosis unproven |
+| #2118 | `239cae9e5` | #1527 | open — 1 of 5 residuals fixed |
+| #2121 | `fbc6f26a2` | #2108 | open — diagnostic shipped, mechanism not |
+| #2126 | `8e7b63387` | — | audit remediation |
+
+Only #2107 is closed, and that asymmetry is the point: three of the four fixes
+are slices, and saying so on the issue is cheaper than a reopen.
+
+## The two defects our own work introduced
+
+Worth leading with these rather than the wins.
+
+**A cross-file test leak that read as CI flake.** The #2107 tests assigned proxy
+variables onto the real `process.env` and restored them in a `finally`. `bun
+test a b` runs every file in ONE process — `--isolate` does not change that — so
+the values outlived the file, and the Lab sandbox rejects any live proxy variable
+as `harness_failure`. 73 macOS failures, zero when the Lab suites ran alone.
+
+**A credential written world-readable.** #2107 made service definitions
+credential-bearing (a proxy URL routinely carries `user:password`) while they
+were still written with a bare `writeFileSync` — 0644 under umask 022, measured.
+In a file where the API token and install state already use 0600, and in a repo
+whose `collectProxyEnv` deliberately reports proxy presence as a boolean so the
+URL never escapes.
+
+The second one merged. It was caught only because the final audit asked a
+question the author never asked — *what mode is that file?* — and then measured
+instead of reasoning.
+
+## What actually caught things
+
+- **Ablation, three times.** The #1527 fix looked right at `failAndClear` and all
+  ten tests still passed — that helper is not on the failure path. The first
+  proxy-leak theory (Bun spreading `null`) produced 50 fail / 50 fail with and
+  without the "fix". A number that does not move is not a fix.
+- **Running the suite the way CI runs it.** Per-suite local green missed the leak
+  entirely, because the defect only exists across suites in one process.
+- **Removing our commits.** The same two files on `origin/dev` went 144 pass / 0
+  fail. That is what converts "CI is flaky" into "we broke it".
+- **An auditor that re-derives rather than re-runs.** Round 1 returned fail on
+  #2121's design; the final round found the P1 and mutation-tested our
+  assertions in a scratch tree to prove they were not vacuous.
+
+## Still unverified, stated rather than filed as done
+
+Everything below is real and none of it is closed by this unit.
+
+- **Windows.** The Windows ACL half of the 0600 fix and the `utf16le` scheduler
+  assets are asserted for mode on POSIX only. `owner-unavailable` — the branch
+  #2108 most needs named — is a Windows icacls path asserted nowhere in the
+  suite.
+- **#1933's diagnosis.** The encoding mechanism is proven in code; that it is
+  *this reporter's* problem is inference from a GitHub display name. If their
+  path is ASCII, the diagnosis is wrong and the issue should stay open.
+- **#1527's other four residuals.** kimi-k3 collapse and the 429 asymmetry depend
+  on #2054. The 429 half may be unprovable while Connect withholds
+  `cache_read_tokens`.
+- **#2108 phase 2.** Waiting on a field report that names a reason. Two candidate
+  triggers, and phase 2 targets one of them.
+- **wp1587**, the deferred tool catalog, was never implemented. Both its blockers
+  cleared, so it is ready, not done.
+
+## Final state
+
+`dev` full suite on `ssh lidge`: **13,505 pass / 15 skip / 0 fail** across 855
+files. Cross-platform CI green on the merged head.
