fix(claude): keep Desktop egress alive and retry picker CA untrust across restarts - #6103

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThis change serializes picker CA rotation and records predecessor certificates for retryable untrust. When cleanup blocks picker startup, an applied Desktop profile can use a blind CONNECT relay. Codex drift healing now uses validated catalog selection and guarded config injection.

Merge Risk: 🟡 Moderate · up to Picker recovery can remain blocked in a legacy PID-reuse case, and the verification record lacks enough timing information for reliable audit. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to Recovery is more conservative about certificate trust and stale configuration writes. The remaining design tradeoff is that, while certificate cleanup is blocked, Desktop’s proxy stays available to other local processes without authentication. It binds only to loopback and does not intercept TLS. Retained concerns

records without startTime to compare the live process start time against the
picker CA owner file’s mtime; treat the record as stale only when the process
started later. Convert Linux start ticks and Darwin start dates to epoch

Record the check execution date.
The results section presents checks as completed, but it does not state when they ran or mark them as pending. The available history does not establish that the review occurred on 2026-09-27, so the 2026-09-28 heading cannot be called future-dated from this evidence. Add the actual execution date, or mark the results as pending until the checks run.

…ross restarts Serialize picker CA publication under the CA lock with a tagged lock result, journal the outgoing public certificate before rotation, drain it before and after startup rotation with acknowledgement only after a confirmed untrust, and serve an applied Desktop profile's egress port with a blind-only CONNECT relay while cleanup is incomplete. Route the Codex config drift heal through the injector directly with the tick's 1-second lock wait and a generation/config write guard.
…er CA owners Address PR review: a drift heal with no usable catalog no longer strips model_catalog_json (the next tick retries once a catalog exists), and a legacy owner record without a start identity no longer blocks rotation forever when its PID was reused (macOS start time vs record mtime).

Summary
Fixes the B9 picker CA regressions flagged by the 2026-09-27 dev→main audit (R1–R3) and hardens the B10 Codex config drift heal. This is the release blocker for the next dev→main promotion.
egressProxyUrlpointed at a dead port. After: startup builds no picker and adds no trust, and instead binds a blind-only CONNECT relay (interceptHosts: [], every tunnel blind) on the applied profile's actual egress port. The profile row, its previous selection and retry intent are untouched; a port held by another process is not taken over. We chose the relay over restoring the pre-picker profile because a restore is an ownership-sensitive Desktop write that discards retry intent and cannot repair the URL a running Desktop already pinned.underPickerCaLocknow returns a taggedacquired | unavailableresult instead of the callback's (void) value, so the normal path publishesca.pem/ca-owner.jsonexactly once and a busy lock publishes nothing outside the lock. A cached ensure restores a missing owner record for our own CA; owner records carry the OS process start identity so a reused PID is not treated as live; a legacy record without one is treated as stale on macOS when the PID started after the record was written.ca.pemis replaced, onepending-untrust.jsonrecord (public PEM + SHA-1/SHA-256, mode 0600, no key material) is written. Startup drains it before and after rotation via a private temp copy of the public PEM, defers while that PEM is still published by a live owner, and acknowledges it only with a successful untrust result. The defaultensurePickerCa(controller enable/trust path) refuses while a record exists, so the startup cleanup order cannot be bypassed.syncModelsToCodex(provider discovery + catalog write) with no lock deadline and checked the timer generation only afterwards. After: it callsinjectCodexConfigdirectly withlockTimeoutMs: 1000and abeforeClientWriteguard that refuses once the generation changed or persisted config differs from the tick snapshot; the catalog path comes from a bounded read-only journal lookup; with no usable catalog the heal is deferred to the next tick instead of strippingmodel_catalog_json; "healed" is reported only after the missing keys are observed on disk.structure/clients/claude-desktop.md,structure/config.md, newINV-PICKER-01/INV-PICKER-02instructure/overview.md, and the Claude Code guide's picker restart section. Plan and results:devlog/_plan/260927_release_train_4/picker-ca/.Known limitation (recorded in
010_ca_publication.md): if another same-user process deletesca-owner.jsonwhile its owner is alive, a second process may treat that CA as ownerless. Refusing ownerless rotation was rejected because every upgrade from the currentmainrelease starts withca.pemand no owner record and would leave the picker permanently off.Verification
