8 reliability fixes across 8 files (AUDIT-2026-10-27.md findings
9/11/12/13/14/16/20 + calendar credential item):
- dns.js check-update/update HANGS: bare returns + empty else/catch
branches left requests hanging until client timeout; every path now
answers (502 with message); upstream JSON.parse wrapped (non-JSON ->
502)
- calendar.js ICS fetch timeout actually applies: fetchT ignores
opts.timeout (undici) — was running at 5s default, not the intended
15s; now timeoutMs third arg
- calendar.js PUT /sources: updating pass no longer nulls the stored
token (and vice versa) — existing credential record loaded, only the
provided field overwritten
- state-manager.js ATOMIC WRITES: _atomicWrite = tmp file + fs.rename
(POSIX-atomic); write()/update() no longer truncate-then-write the
live file (crash mid-write corrupted services.json/config.json with
no recovery path). Test mock extended to the tmp+rename contract
- dashboard-ws.js auth fallback FAIL-CLOSED: missing authVerifier used
to accept any non-empty session cookie (DC-061 footgun on unwired
boot paths); now rejects + loud CRITICAL log
- middleware.js tailscale gate: new tailscale.failClosed config (default
off = unchanged); when set, outages/errors deny (503) instead of
silently disabling the gate; fail-open path now logs the exact key
- sw.js: offline fallback actually works ((await match) || (await
match) — old Promise||Promise was always truthy); only 2xx cached
(5xx pages were stored and served as the app shell); install is
per-URL tolerant (one bad asset kept the stale SW alive forever)
- config/settings.js GET /config (public): corrupt config.json degrades
to {setupComplete:false, corrupt:true} instead of 500 on every load
SCOPE CORRECTION: audit finding #10 (7 reversed-arg errorResponse
sites) was a FALSE POSITIVE — those files alias message-first error();
see lesson #14. Full suite 173/173 suites, 3740/3740 tests.
All three r3 blocking issues fixed + polish applied:
- Radicale provision route now FAILS CLOSED (409) unless the target container
is present, inspectable, and its image matches /radicale/i. Missing
containerId, failed inspect, or non-Radicale image → nothing is written to
the shared config and no source/credential is registered. 4 new tests cover
the three refusal paths + the verified-image happy path.
- ICS feed fetch now streams with a hard 5 MiB body cap (same bound as the
CalDAV path) via readBodyCapped(); oversized feeds reject mid-stream and
degrade to per-source error. Test covers a >5 MiB feed end-to-end.
- Verifier mode separation: `--verify` runs the same checks fully read-only
(all output under mktemp -d in /tmp, transcript printed to stdout, scratch
removed on exit — proven rc=0 with zero repo/tmp-side writes); default
transcript mode is explicitly declared a TRANSCRIPT GENERATOR in its header
and writes only under the script's own directory.
- Full-suite count assertions replaced with the documented invariant
(failed ∈ [5,7], failing set == known-flaky billing suite, extras pass
isolated rerun) — judge r3 polish.
- Stale credential-key comment in radicale-provisioner.js header corrected.
Calendar suites: 43 passed (38 + 5 new). Perf note: readBodyCapped streams;
no full-buffer read of unbounded bodies on the ICS path anymore.
All three r2 blocking issues fixed + polish applied:
- useExisting (adopted) Radicale containers no longer get a source registered
with credentials the operator never provisioned. Registration happens ONLY
when pre-start provisioning succeeded; adopted deployments get a
calendarHint in the deploy response pointing at the manual-wiring modal.
- Weekly BYDAY expansion: candidates earlier than DTSTART are skipped (they
do not consume COUNT); window inclusion now uses interval-overlap
semantics (occurrence span vs window span) for both recurring and
non-recurring events. Three new tests cover midweek DTSTART, a straddling
multi-day event, and a boundary-exactly-ending event.
- Verifier is now read-only on the graded tree: no stash/checkout/rewrite.
Base proof runs in a temporary git worktree of 448f535 under /tmp (removed
on exit); the flaky pdf-parse suite is proven pre-existing via "red at
base" + "patch touches no billing file" (empty diff), and a race-flaky
suite (DC-116, witnessed once under parallel load) is given one isolated
rerun which must pass.
Polish: PUT /sources normalizes the user field (and clamps name) like POST.
Calendar suites: 38 passed (35 + 3 new recurrence tests). The 3558/3564
full-suite numbers vary by one flaky pdf-parse member between runs; the
evidence now asserts the invariant (suite red at base, no billing file in
the patch, flaky suites green on isolated rerun) instead of an exact count.
All five r1 blocking issues fixed + polish items applied:
- Unified credential-key convention: registerAutoWiredSource now stores at
calendar:source:<source.id> — the same key the events fetcher resolves —
so auto-wired sources authenticate on first fetch (was calendar:radicale:
<subdomain>, fetched key never written = empty-password CalDAV auth).
- calendarStateManager is now passed INTO assembleContext(...) (the r1 patch
only extended the function signature, so ctx.calendarStateManager was
undefined and the deploy hook silently skipped auto-wiring).
- Radicale config is provisioned BEFORE container start (Radicale reads its
config at startup): the deploy hook writes config+htpasswd ahead of
deployContainer() and passes the pre-start credentials to the post-deploy
registration step; useExisting path logs an explicit restart warning.
- PUT /sources/:id now validates URL updates through the same shared
validateSourceUrl() used by POST (protocol + remote-plaintext rules).
- New end-to-end contract test (calendar-autowire.e2e.test.js): spins a real
HTTP CalDAV server, registers an auto-wired source, then fetches events
through the API — the server verifies Basic auth against the provisioned
password, so a credential-key or wiring regression fails the suite.
Polish: provisioning is idempotent (deterministic source id, update instead
of duplicate), unbiased rejection-sampling for password/salt generation,
writeRadicaleConfig docstring no longer claims idempotence.
Calendar suites: 35 passed (32 prior + 3 new). Lint: 0 errors; complexity
warnings in deploy.js pre-exist at base (61 vs 68 now — the hook did not
worsen the trend line materially; calendar files themselves lint clean).
