Steps use checkbox (`- [ ]`) syntax +> for tracking. + +**Goal:** Land the revised Slice 5 of the DEV-0006 codex managed-launch spec — drain the parked +`RemoteProxyEvent` stream into the existing identity/activity tails, arbitrate locator-vs-proxy, +enforce `require_candidate_persistence`, complete the structural prerequisites, resolve +D-C-REVISIT, flip `FRESHELL_CODEX_MANAGED_LAUNCH` default ON, and close DEV-0006 + DEV-0008. + +**Architecture:** A per-terminal drain task spawned inside `CodexTerminalLaunchManager::adopt` +forwards proxy events (tagged with terminal id + plan cwd) into a set-once process-wide sink +channel; a single router task in `freshell-ws` (which owns `WsState`) consumes the channel and +routes `Candidate` → `adopt_codex_identity`, turn events → a new third activity-tracker lane, and +everything else → minimal logging. The candidate-persistence gate is ported into the proxy hub +(hold `turn/start`/`thread/fork` until the router persists the candidate, 45 s capture timeout, +legacy parity). The flag flip is preceded by the D-C-REVISIT resolution (a sidecar planning +budget covering both doors + moving the REST spawn-gate acquire to after the codex plan). + +**Tech Stack:** Rust (tokio, tokio-tungstenite), crates `freshell-codex`, `freshell-ws`, +`freshell-activity`, `freshell-freshagent`, `freshell-platform`, `freshell-server`; markdown +record ledgers under `port/oracle/`. + +**Spec:** `docs/plans/2026-07-19-dev0006-codex-launch-planning-spec.md` (revised Slice 5, +lines 245–320; §6 fences; §8 reconciliation). The spec is authoritative. + +**Workspace:** the worktree `/home/dan/code/freshell/.worktrees/codex-managed-launch-s5` +(branch `feat/codex-managed-launch-s5`, based on `main` @ `6d0e285b`).

The + argv resolver is done (G-X1/G-X2/G-W2); feed it a URL, don't touch it. +- **NO touching `server/ shared/ src/`** (campaign additive-only purity rule) and **no behavior + change to non-codex modes** (spec §6). +- **Sidecar-level re-plan-on-loss stays deferred** (spec §6 fence): `RepairTrigger` / + lifecycle-loss handling is log-only; recovery belongs to the auto-resume orchestrator. +- **Do NOT reorder the pinned identity write tail** (`codex_identity.rs:182-185`): + `identity.upsert` → `registry.set_meta` → awaited `ledger_resolve_identity` → broadcast + `terminal.session.associated` THEN `terminal.meta.updated` → activity hub. +- **Meta enrichment (git branch/dirty, tokenUsage) is out of scope** (spec S5 out-of-scope + list) — `TerminalMetaRecord` enrichment fields stay `None`. +- **WS raw-resume "alignment" is out of scope** (spec S5 out-of-scope list). +- Legacy-parity constants (from `server/coding-cli/codex-app-server/remote-proxy.ts`): + candidate capture timeout **45_000 ms** (`:94`), request hold timeout **5_000 ms** (`:93`), + max held gate frames **32**; gated client methods on initial capture: exactly + **`turn/start` and `thread/fork`** (`remote-proxy.ts:422-425`). +- Before every commit, run for each touched Rust crate: `cargo fmt --all` and + `cargo clippy -p --all-targets -- -D warnings` (for `freshell-codex` also + `cargo clippy -p freshell-codex --features real-transport --all-targets -- -D warnings`, + mirroring `.github/workflows/rust-clippy.yml:41-56`). +- Line numbers cited below are from `main` @ `6d0e285b` and WILL drift as tasks land — + re-anchor by searching for the quoted code, not by line number. +- README.md is the only end-user markdown doc; everything this plan adds under `docs/plans/` + and `port/oracle/` is working/record documentation. + +## Recorded Decisions (the spec's DECIDE items — read before implementing) + +These are the decisions the spec explicitly requires S5 to make and record.

Instead of + converting the 12 `::global()` call sites to DI, `freshell-codex` gains a **set-once + proxy-event sink channel** (the spawn-gate set-once-handle precedent the spec itself names). + The drain task never needs `WsState`; all `WsState` access happens in the `freshell-ws` + router on the far side of the channel. This honors "spawn ONE per-terminal drain task at + `CodexTerminalLaunchManager::adopt` (covers all three adopt sites)" literally — REST-created + panes included, even though `freshell-freshagent` cannot name `WsState`. +- **D-03 (S5.b, locator-vs-candidate precedence):** *For managed panes the proxy candidate is + authoritative and the association locator never arms; for unmanaged panes the locator is the + only writer (no proxy exists). On the same terminal, first bind wins: the router ignores a + later proxy candidate carrying a different session id (identity moves only through the fork + rebind lane).* Suppression happens at arm time (`maybe_arm`), never via `locator.disarm` + (disarm would also kill the fork watch, `codex_locator.rs:263-267`). +- **D-FORK (S5.a fork candidates):** Proxy `Candidate` events with + `source == CandidateSource::ThreadForkResponse` are **deliberately ignored** (logged at + debug). The landed disk fork-watch lane (`locator.watch_fork` → `tick_forks` → + `rebind_codex_identity`, D7/A13/A8 guards) owns fork rebinds; the router registers + `watch_fork` for managed panes right after candidate adoption so managed fresh panes get + the same fork coverage resume panes already have (`terminal.rs:2442-2446`). +- **D-REASON (S5.d.3, binding_reason):** `CodexLaunchPlan.binding_reason` is **explicitly + dropped** at adoption. Rationale: the Rust adoption tail derives adopt-vs-rebind from + context (its own reason vocabulary), no Rust protocol frame ever carried + `sessionBindingReason`, and the only legacy consumer (`codex-activity-tracker.ts`) is + superseded by the ported tracker which does not need it. The wire-string pin test + (`launch_plan.rs:414-417`) stays. Recorded in code docs (Task 3) and the DEV-0006 + closure_progress (Task 13). +- **D-C-R (S5.e precondition, D-C-REVISIT):** Two-part resolution. (1) A **sidecar planning + budget** inside `CodexTerminalLaunchManager::plan_create_with_retry` — a semaphore of 2 + concurrent codex plans with a bounded 30 s wait that fails fast — covering ALL doors (WS + create, WS restore, WS auto-resume, REST). (2) The **REST door's spawn-gate acquire moves + to after the codex plan** (inside `settle_gated_create`, immediately before the PTY fork), + mirroring the WS auto-resume door's plan-before-acquire ordering with the same + discard-on-rejection cleanup (`terminal.rs:2925-2929` precedent). Residual: WS + restore-creates still plan under the caller-held permit (`create_gate.rs:74`), now bounded + by the budget (at most 2 such long holds server-wide); accepted and recorded in the §D-C + addendum (Task 13). +- **D-GATE-SOFT (S5.c timeout consequence):** On candidate-capture timeout/failure, legacy + kills the terminal (`failCodexFreshIdentity` → `killAndWait`). The port answers held frames + with JSON-RPC `-32000` errors, closes all proxy connections, and emits + `RepairTrigger::CandidateCaptureTimeout` which the router **logs** (S5.a says repair + handling is minimal; re-plan-on-loss is fenced off). The pane survives with honest identity + absence and a visibly dead TUI remote. Recorded in Task 13. +- **D-CLOSED (S5.e records):** `port/oracle/DEVIATIONS.md`'s declared status vocabulary + (`:25`) is extended with `closed`, because the spec instructs "DEV-0006 → `closed`" and no + closed precedent exists in the ledger. + +## File Structure (what gets created/modified where) + +- `crates/freshell-codex/src/remote_proxy.rs` — identity gate (hold/release/fail/timeout), + new `HubMsg` variants, options timeouts, `RemoteProxyRepairTrigger::CandidateCaptureTimeout`. +- `crates/freshell-codex/tests/candidate_gate.rs` — NEW: gate integration tests (pure-Rust + fake upstream). +- `crates/freshell-codex/src/launch_lifecycle.rs` — persistence plumbing on sidecar+manager, + drain task + set-once sink, sidecar planning budget, pub spawn helpers. +- `crates/freshell-codex/src/launch_plan.rs` — flag default flip, binding_reason decision doc. +- `crates/freshell-activity/src/codex.rs` — third (proxy) lane + generalized cross-lane dedupe. +- `crates/freshell-ws/src/activity.rs` — `HubEvent::CodexProxyTurn` + `note_codex_proxy_turn`. +- `crates/freshell-ws/src/codex_proxy_route.rs` — NEW: the router (candidate/turn/fork/repair + routing, D-03 rule, persistence release). +- `crates/freshell-ws/src/codex_association.rs` — `should_arm_codex_locator` + + managed-suppression parameter. +- `crates/freshell-ws/src/terminal.rs` — arm-site suppression, gate-test updates, comment + updates. +- `crates/freshell-ws/src/lib.rs` — `pub mod codex_proxy_route;`. +- `crates/freshell-server/src/main.rs` — boot wiring (sink install + router spawn). +- `crates/freshell-freshagent/src/codex.rs` — spawn-helper unification (delete duplicated + const/fns, use canonical spec + shared helpers). +- `crates/freshell-freshagent/src/terminal_tabs.rs` — REST acquire move, D-C marker update, + gate-helper test updates. +- `crates/freshell-ws/tests/{codex_fork_rebind,codex_locator_activity,codex_session_ref_resume,codex_candidate_inert}.rs` + — pin the flag OFF (`set_var(.., "0")`). +- `crates/freshell-ws/tests/codex_managed_launch_e2e.rs` — inverted legs + resume phase. +- `crates/freshell-platform/src/cli_launch_goldens.rs` — retire G-X0, promote G-X1/G-X2. +- `port/machine/specs/cli-argv-fidelity.md`, `port/machine/STATE.yaml`, `port/HANDOFF.md` — + golden/record mirrors. +- `port/oracle/DEVIATIONS.md`, `port/oracle/EQUIVALENCE-REPORT.md`, + `docs/plans/2026-07-27-rest-spawn-gate.md`, + `docs/plans/2026-07-19-dev0006-codex-launch-planning-spec.md` — closures + decision records. + +Task order is dependency order: 1→2→3 (gate, plumbing, drain) can be reviewed independently; +4→5→6 (activity lane, hub API, router) build on 3; 7 (locator suppression) needs 6's rule; 8 +(spawn unification) is independent; 9 (D-C) must precede 10 (flip); 10–12 are the flip and its +test estate; 13 closes the records. + +--- + +### Task 1: Candidate-persistence gate in the proxy hub (S5.c core) + +**Files:** +- Modify: `crates/freshell-codex/src/remote_proxy.rs` +- Test: `crates/freshell-codex/tests/candidate_gate.rs` (new) + +**Interfaces:** +- Consumes: existing `CodexRemoteProxy::start`, `Hub`, `HubMsg`, `handle_client_frame` + (`remote_proxy.rs:723-782`), `send_json_rpc_error_to_client`, `scan_json_rpc_envelope`. +- Produces (later tasks rely on these exact names): + - `impl CodexRemoteProxy { pub fn mark_candidate_persisted(&self); pub fn fail_candidate_capture(&self, message: &str); }` + - `RemoteProxyRepairTrigger::CandidateCaptureTimeout` (new enum variant, fieldless) + - `CodexRemoteProxyOptions { pub candidate_capture_timeout_ms: u64, pub identity_gate_hold_timeout_ms: u64, .. }` + (defaults below; `CodexRemoteProxyOptions::new` keeps its current 2-arg signature and + fills the defaults) + - `pub const CANDIDATE_CAPTURE_TIMEOUT_MS: u64 = 45_000;` + - `pub const IDENTITY_GATE_HOLD_TIMEOUT_MS: u64 = 5_000;` + - `pub const MAX_HELD_IDENTITY_GATE_FRAMES: usize = 32;` + +Legacy reference (parity target): `server/coding-cli/codex-app-server/remote-proxy.ts` — +gate holds client→upstream **requests** with method `turn/start` or `thread/fork` only +(`:422-425`); `DEFAULT_CANDIDATE_CAPTURE_TIMEOUT_MS = 45_000` (`:94`, overridable `:139`); +`DEFAULT_REQUEST_HOLD_TIMEOUT_MS = 5_000` (`:93`, armed on the FIRST held frame); on +timeout/failure the held frames are answered with JSON-RPC `-32000` errors (never forwarded), +all connections closed, and a `repair_trigger{kind:'candidate_capture_timeout'}` is emitted. +`pauseCandidateCapture`/`resumeCandidateCapture` belong to the fork-handoff gate and are NOT +ported (codexForkHandoff is fenced off — record a one-line code comment saying so). + +- [ ] **Step 1: Write the failing tests** + +Create `crates/freshell-codex/tests/candidate_gate.rs`.

Task 1's candidate-persistence gate would break the existing remote_proxy_relay.rs fork-rewrite tests (all relay tests construct the proxy with require_candidate_persistence == true) while the plan claimed pre-existing tests stay green. Added Step 3i scheduling the relay-suite remediation (release the gate in the two thread/fork rewrite tests), listed the file in Task 1 Files and the File Structure map, and corrected Step 4's expected-pass rationale. 2.

S5's designed mechanism has been pre-empted by a different architecture +Spec S5 = "Consume the proxy's captured candidates to mint a durable sessionRef, drive codex-activity-tracker-equivalent turn events, and emit terminal.meta.updated." Each of the three outcomes now exists via the restart-resilience campaign's **disk-based** machinery (locator + ledger + activity lane), which works with the flag OFF and for which the proxy is irrelevant. The proxy's event stream is deliberately parked unconsumed (`launch_lifecycle.rs:373-375` `_events`, "Held (unconsumed) … for S5"). What S5 uniquely still owns: +- argv/behavior parity: `--remote` 4-tuple + `features.apps=false` (flag flip); +- proxy-only fidelity: fork-request rewrite, fs-changed repair triggers, in-band candidate capture (vs. disk polling); +- G-X0→G-X1 golden swap; DEV-0006 + DEV-0008 record closure; +- meta enrichment still missing everywhere (git fields, tokenUsage). +An S5 that re-implements binding/activity from proxy events as specced would create a **second identity writer**, violating the single-writer discipline established 07-26 (`4767b7ec` retired the candidate.persisted writer precisely to get to "exactly one writer owns codex identity facts"; misbind guards at `857c9d48`). + +## F3. The "whole-or-not" DEV-0008 fence was overtaken in practice — and the deviation record is now stale +Spec §6: "NO partial DEV-0008 shipment… Slice 5 lands whole or not at all." In practice: a create-time `terminal.meta.updated` slice shipped 07-16, an association-time slice shipped 07-24/26, each with its own review trail (P0.3 plan; rollout-locator plan). `port/oracle/DEVIATIONS.md:588-653` (DEV-0008) still reads "rust emits NO terminal.meta.updated frames" / "open gap" — **contradicted by shipping code**; no closure_progress was appended (only DEV-0006 got one, dated 07-22). Whoever executes S5 should treat both the spec fence and the DEV-0008 record text as historical, not current. + +## F4. Classification of the four "S5 follow-ups recorded from the S4 review" +1. **Spawn-helper unification — UNTOUCHED.** `freshell-freshagent/src/codex.rs::spawn_sidecar` (`codex.rs:1959`, 5 call sites) still carries its own spawn mechanics; `launch_lifecycle.rs:9-11` still says "a follow-up refactor points `codex.rs` here too." No commit since 07-22 touches this seam. +2. **Singleton vs DI — UNTOUCHED and further entrenched.** `CodexTerminalLaunchManager::global()` now has ~13 call sites (`terminal.rs:1135,1336,2333,2375,2926,2969,2980`; `terminal_tabs.rs:1298,1439,1548,1588`; `main.rs:1204`). Meanwhile the codebase built DI precedents S5 could reuse (`PaneIdentitySink`, `SessionIdentityLookup`, the spawn-gate set-once handle on `FreshAgentState` + boot assertion `ce88e23c`) — the pattern exists; the manager was never migrated. +3. **binding_reason consumer — UNTOUCHED, and arguably SUPERSEDED.** `binding_reason` (20 hits) and `get_codex_session_binding_reason` remain confined to `launch_plan.rs`; the only `sessionBindingReason` mention outside is a legacy-parity comment (`cli_launch.rs:84`). No Rust registry consumer exists. But identity binding is now owned by ledger binding rows + `adopt_codex_identity`, which have their own reason vocabulary (`RetiredReason::{Superseded,Closed,GcExpired}`, pending markers). S5 must decide whether a registry `sessionBindingReason` is still meaningful or whether the plan field should feed the ledger/adoption tail instead. +4. **Recovery re-plan-on-loss — UNTOUCHED at the sidecar layer, scope reshaped above it.** `launch_lifecycle.rs:30-36` still records the deferral. Since then, a terminal-level auto-resume orchestrator (`6379f24f`, `4b417ab0`, flap breaker `544901fa`, cancel `2edbbc9d`) respawns crashed agent terminals server-side. Sidecar-loss re-planning added by S5 must compose with (not race) auto-resume and the spawn gate. + +## F5. The flag flip acquired a NEW documented precondition the spec doesn't know about +`D-C-REVISIT(FRESHELL_CODEX_MANAGED_LAUNCH)` tripwire (`e2e9cbc3`, 07-29; markers at `launch_plan.rs:56-59` and the REST call site `terminal_tabs.rs:1271`): the managed-launch plan runs UNDER the shared WS+REST spawn permit, worst case ~226 s hold (5 attempts × 45 s `SIDECAR_START_BUDGET`), and the default flip "cannot ship without hitting this decision" (rest-spawn-gate.md:109-123). Also `f3cef839`: spawn-gate rejection must clean up codex/MCP side effects. S5's "flag default flips" step is therefore no longer a one-line change + golden swap. + +## F6. Golden state: unchanged in substance, drifted in anchors +`g_x0_codex_shipped_deviation_shape_dev_0006` still pins the live path — now at `cli_launch_goldens.rs:738` (spec cites :623-650). G-X1 (:262) / G-X2 (:290) / G-W2 (:609) still pass as resolver goldens. No swap occurred; consistent with the flag still defaulting OFF. Spec's §7 index has drifted throughout (`terminal.rs` codex branch now ~:1038-1135 and :2005+, not :831-835). + +## F7. The raw-resume follow-up was overtaken by sessionRef canonicalization +Spec follow-up: "consider aligning the WS path's raw-resume acceptance to the legacy reject."

S5 = spawn a per-terminal drain task at +`CodexTerminalLaunchManager::adopt` (covers all three adopt call sites: WS create +`terminal.rs:2374-2383`, auto-resume respawn `terminal.rs:2977-2987`, REST +`terminal_tabs.rs:1588-1590` — hooking the manager once beats hooking three call sites). +Problem: the manager lives in `freshell-codex` and cannot see `WsState`; spec follow-up 2 +(spec :190-192) already recommends threading it via `WsState`/`FreshAgentState` DI in S5. + +**F2 — The binding write path already exists; reuse it whole.** +`RemoteProxyEvent::Candidate` → `codex_identity::adopt_codex_identity` +(`codex_identity.rs:60-74`) gives S5, for free and in the pinned order +(`apply_codex_identity`, `:186-227`): identity registry upsert, registry meta, durable +sessionRef-keyed pane-ledger row (fsync-before-announce), `terminal.session.associated` + +`terminal.meta.updated` broadcasts, and activity-hub bind (`bind_codex_session` / +`attach_codex_rollout`, `activity.rs:257,:277`) — plus the hijack/misbind guards +(`codex_claim_refused`, `:128-179`). The Rust pane ledger IS the functional equivalent of +legacy's durability store (`pane_ledger.rs:8-13` "the resume-invocation record"). S5 should NOT +port `durability-store.ts`/`durability-proof.ts` wholesale. + +**F3 — Turn events map to existing tracker seams, but need a third-lane dedupe.** +Legacy: proxy turn events → registry `codex.turn.started/completed` → +`CodexActivityTracker.onTurnStarted/onTurnCompleted` (`terminal-registry.ts:1920-1943`, +`codex-activity-wiring.ts:90-91`, `codex-activity-tracker.ts:238,:248`), with explicit +BEL/JSONL/app-server triple dedupe (`codex-activity-tracker.ts:438`). Rust tracker +(`freshell-activity/src/codex.rs`) currently dedupes TWO lanes (PTY BEL + rollout reconcile, +`swallow_next_bel` `:30-36,:124-125`). Wiring proxy TurnCompleted directly would double-chime +`terminal.turn.complete`; the tracker's dedupe surface must grow a third clock domain. + +**F4 — `terminal.meta.updated` parity target is already satisfied by F2's tail.** +Frame + broadcast shape landed (`server_messages.rs:121`; +`codex_identity.rs:258-276`; create-time slice `terminal.rs:2456-2488,:3230-3269`). What DEV-0008 +still lacks for codex panes is the association-time trigger — exactly the candidate bind. Git +enrichment / token usage remain deliberately unported (DEV-0008 record, +`DEVIATIONS.md:603-655`) — S5 does not need them to close the record as adjudicated (closure = +"port ... terminal.meta.updated WHEN the coding-CLI ... session-association subsystem is +ported", `DEVIATIONS.md:645-650`). + +## B. Overlaps / conflicts (composition effects) + +**F5 — Locator-vs-proxy dual identity source (needs an explicit decision).** +The landed codex rollout locator (2026-07-26 plan; `codex_association.rs:33-47,:57-87`; +armed at `terminal.rs:2405-2450`) will keep running Enter-anchored inference for managed panes. +Same-terminal re-adopt is idempotent (`codex_identity.rs:133-135`), so agreement is benign, but +S5 should suppress arming (or `locator.disarm`, `codex_locator.rs:263`) when a managed launch +exists — otherwise two writers race for first-bind and the locator does wasted fs walks per +Enter. Risk if unaddressed: a foreign same-cwd rollout appearing in the submit window could +bind BEFORE the proxy candidate lands (locator sole-match wins the race), producing a wrong +binding the candidate then cannot correct (bound-elsewhere guard refuses... note the guard +refuses claims bound to OTHER terminals, not corrections of THIS terminal — the candidate would +overwrite via re-adopt only if ids differ, which `identity.upsert` allows; semantics here need a +deliberate rule, not an accident). + +**F6 — Fork handling: prefer the landed locator fork lane; don't port codexForkHandoff.** +Proxy side-effects include fork-response candidates + fork-request rewrite +(`remote_proxy_side_effects.rs`); legacy has a whole `codexForkHandoff` state machine +(`terminal-registry.ts:2040-2060`). Rust already solves the user-visible incident with +`watch_fork`/`tick_forks` → `rebind_codex_identity` (D7/A13 guards), pinned by +`tests/codex_fork_rebind.rs`. S5 can treat proxy fork candidates as ordinary rebind inputs or +ignore them; porting fork-handoff would duplicate a solved problem and add a second rebind +driver. + +**F7 — `require_candidate_persistence` is recorded but unenforced (whole-or-not hazard).** +Proxy never holds frames or times out capture (`remote_proxy.rs:160-162,:262-271`; +`launch_lifecycle.rs:21-25`). Legacy gates relay on persist and fails identity on +`candidate_capture_timeout` (`terminal-registry.ts:1911-1917,:1946-1951`). If S5 ships binding +without the gate, a crash inside the candidate→ledger window yields a running-but-unrestorable +pane — the exact "confidently divergent vs honestly absent" class council rejected +(`DEVIATIONS.md:608`). S5 must either port the gate or get an explicit adjudicated waiver. + +**F8 — `binding_reason` / ownership metadata have no consumers (S5 leftovers by design).** +`CodexLaunchPlan.binding_reason` computed but unconsumed (spec :193-195); +`update_ownership_metadata` records in memory only (`launch_lifecycle.rs:26-28,:660-668`); +generation is hardcoded 0 at every adopt site (vs legacy's per-recovery increments). Legacy +consumers: `sessionBindingReason` drives claude start/resume + `codexUnconfirmedInputAt` +(`terminal-registry.ts:1581,:1676-1679`). Scope these consciously into or out of S5. + +**F9 — Reconcile/rebind/lease machinery composes cleanly — no change needed.** +Candidate-derived ids claim no D8 lease (later-resolved identities "claim nothing", +`terminal.rs:1160-1182`); reconcile (`reconcile.rs:142-215`) and inventory +(`lib.rs:475-484`) read the same identity registry + ledger the F2 tail writes; restore resume +derivation (`terminal.rs:1626-1710`, pinned by `tests/codex_session_ref_resume.rs`) picks the +binding up automatically on the next restore.

AUTH — mutating routes, `lan-info`, `status` + +**Status: PASS for what exists; N/A for the four absent routes.** + +`GET /api/network/status` (`crates/freshell-server/src/network.rs:90-93`) checks auth as +the **very first statement**, before the `OnceCell` live-facts resolution at `:97-111` +that spawns read-only subprocesses: + +```rust +async fn network_status(State(state): State, headers: HeaderMap) -> Response { + if !is_authed(&headers, &state.auth_token) { + return crate::boot::unauthorized(); // network.rs:91-93 + } + let facts = state.facts.get_or_init(...) // expensive work strictly after +``` + +This ordering is correct and matters: it means an unauthenticated caller cannot make the +server fork `netsh.exe`/`ipconfig.exe`, so there is no pre-auth subprocess-amplification +DoS. + +The gate itself (`crates/freshell-server/src/boot.rs:686-708`) accepts `x-auth-token` or +the `freshell-auth` cookie, rejects empty values, and compares via +`freshell_api::constant_time_eq` (`crates/freshell-api/src/lib.rs:91-100`) — a +length-check-then-XOR-accumulate loop with no early exit. Live: missing token → 401, +wrong token → 401. + +**Note (not a finding, a requirement for the next slice):** `is_authed` is applied +per-handler, not as a router-wide layer. Every one of the four new mutating routes must +repeat that call as its first statement. Given the pattern, a single omission is a +critical auth bypass, and nothing structural prevents it. I recommend the mutating +routes be mounted behind a `middleware::from_fn` auth layer rather than relying on +four hand-written copies. + +--- + +## 2. INPUT — unknown fields, wrong types, hostile hosts + +**Status: N/A for the absent routes. The adjacent live path that writes the same +state (`PATCH /api/settings`) is SOUND on hostile hosts; one lenient behavior noted +as informational.** + +The `host` value is not a free string.

If the brief's +"unknown fields rejected 400" is a hard contract for the new mutating routes, they will +need `#[serde(deny_unknown_fields)]` explicitly; they will not inherit it. + +**Disclosure:** these probes mutated live settings (`network.configured` / `host`) on the +running server. Final persisted state is `{"configured": true, "host": "0.0.0.0"}`, which +matches the pre-probe state — the accepted requests wrote the values that were already +there. No restart was performed and no approval was required. + +--- + +## 3. COMMAND CONSTRUCTION — the real risk + +This is where the substantive findings are. I traced every path from input to a command +string across `elevated.rs`, `firewall.rs`, and `port_forward.rs`. + +### 3a. Quoting analysis of `build_elevated_powershell_args` — CORRECT + +`crates/freshell-platform/src/elevated.rs:24-30`: + +```rust +let escaped = script.replace('\'', "''"); +format!("Start-Process powershell -Verb RunAs -Wait -ArgumentList '-Command', '{escaped}'") +``` + +The `'` → `''` doubling is the correct escape for a PowerShell **single-quoted** literal. +Single-quoted PowerShell strings do not interpolate `$`, backtick, or `"`, so the only +way out of the literal is a bare `'`, and that is exactly what is doubled. I attacked it +directly with `1.2.3.4' ; calc ; '` and confirmed the quotes come out doubled with no +breakout: + +``` +... connectaddress=1.2.3.4'' ; calc ; '' connectport=3001; ... +``` + +The argv is also passed as a real vector to `std::process::Command::args` +(`crates/freshell-platform/src/lib.rs:314-324`) — **no shell, no `cmd.exe`, no +`ArgvQuote` round-trip**. So `cmd` metacharacters (`&`, `|`, `^`, `%VAR%`) are inert at +this layer. The quoting function is not the weakness. + +### 3b. FINDING NET08-A — unvalidated `wsl_ip` is injected into the elevated script body + +**Severity: MEDIUM as shipped (unreachable — no caller, no route). HIGH the moment +`configure`/`configure-firewall` is wired and passes an attacker-influenced IP.** + +**Location:** `crates/freshell-platform/src/port_forward.rs:327-345`, specifically the +interpolation at `:338`; propagated via `build_wsl_port_forwarding_plan` +(`:413-471`, script built at `:465`, normalized at `:468`). + +```rust +pub fn build_port_forwarding_script(wsl_ip: &str, ports: &[u16], cleanup_ports: &[u16]) -> String { + ... + cmds.push(format!( + "netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 \ +listenport={port} connectaddress={wsl_ip} connectport={port}" // :338 — raw interpolation + )); +``` + +`wsl_ip` is a `&str` with **no validation at this boundary**. Ports are `u16` and +therefore safe; the rule name is a hardcoded space-free constant; `wsl_ip` is the sole +free-form value in the entire script. + +The escaping in 3a does **not** save you here, because the injected content is placed +*inside* the script that is then wrapped — the attacker's `;` is a legitimate PowerShell +statement separator within the single-quoted `-Command` payload, which PowerShell parses +after unwrapping. PoC (executed, output verbatim): + +``` +input wsl_ip = "1.2.3.4; Start-Process calc.exe; #" + +script = netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=3001 + connectaddress=1.2.3.4; Start-Process calc.exe; # connectport=3001; ... + +elevated arg[1] = Start-Process powershell -Verb RunAs -Wait -ArgumentList '-Command', + '... connectaddress=1.2.3.4; Start-Process calc.exe; # connectport=3001; ...' +``` + +The trailing `#` comments out the rest of the line, yielding a clean injected statement +that would execute **elevated, post-UAC**. No quote characters are needed, so the `''` +escaping is bypassed entirely rather than defeated. + +I also confirmed the full plan builder propagates it (`build_wsl_port_forwarding_plan` +with `wsl_ip = "1.2.3.4; calc.exe"` → `Ready { script }` containing `calc.exe`), so the +defect is not confined to the low-level builder. + +**Why it is only MEDIUM today:** `build_port_forwarding_script`, +`build_firewall_only_script`, `build_port_forwarding_teardown_script`, +`spawn_elevated_powershell`, and `ConfirmationGate::request_elevation` have **zero +non-test callers** (grep across all of `crates/`; the only hits are the `pub use` +re-exports at `lib.rs:68,81`). Nothing can reach line 338 at runtime. + +**Exploit sketch (post-wiring).** The intended producer is `get_wsl_ip` +(`port_forward.rs:549-559`), which parses `ip -4 addr show eth0` / `hostname -I`. Both +parsers **do** validate with `is_ipv4_shape` (`:111-118`, `:529`, `:543`), so the +*intended* path is currently safe. The exposure is that the safety is an accident of the +producer, not a property of the consumer: +1. A future `POST /api/network/configure` accepts a caller-supplied or + config-supplied connect address (an entirely natural API shape for this feature); +2. it flows to `build_port_forwarding_script` as `wsl_ip`; +3. the operator clicks through the UAC prompt they were already going to click; +4. the injected statement runs as Administrator. + +**Recommended fix (fix the system, not the symptom):** make the type system carry the +guarantee. Introduce a validated `Ipv4Addr`-backed newtype (or take `std::net::Ipv4Addr` +directly) as the parameter type of `build_port_forwarding_script` / +`build_wsl_port_forwarding_plan`, so an unvalidated string is a **compile error** rather +than a code-review obligation. `is_ipv4_shape` should be enforced at the builder +boundary, not only at the two parsers. Add a red test asserting a hostile IP is rejected. + +### 3c. FINDING NET08-B — newline smuggling is not blocked + +**Severity: LOW as shipped (same unreachability as NET08-A; strictly a sub-case of it).** + +**Location:** same interpolation, `port_forward.rs:338`. + +Neither the builder nor `build_elevated_powershell_args` strips or rejects `\r` / `\n`. +PoC output shows a literal newline surviving into `arg[1]`: + +``` +... connectaddress=1.2.3.4 +Start-Process calc.exe + connectport=3001; ... +``` + +In a PowerShell single-quoted here-string context a newline is a statement separator, so +this is a second injection primitive that does not require `;`. Same root cause and same +fix as NET08-A — an `Ipv4Addr` type makes both impossible. + +### 3d. `2>\$null` → `2>$null` normalization — CORRECT, and worth stating why + +`normalize_script_for_elevated_powershell` (`port_forward.rs:264-266`) does +`script.replace("\\$", "$")`. This looked like a candidate escaping bug, so I checked it +adversarially: it is a **de-escaping** step, and it only ever removes a backslash before +a `$`. It cannot introduce a quote, a `;`, or a newline, and it runs on a string whose +only variable component is `wsl_ip` (already covered by NET08-A). It does not widen the +attack surface. The dual-form convention (raw `2>\$null` for the `sh`-interpolated path, +normalized `2>$null` for the direct-to-PowerShell path) is documented at +`port_forward.rs:6-13` and `firewall.rs:13-19` and is golden-tested both ways. + +### 3e. `firewall.rs` builders — SOUND + +Every builder in `firewall.rs` interpolates **only `u16` ports**: +`build_windows_firewall_delete_commands` (`:248-258`), +`build_windows_firewall_add_commands` (`:261-272`), +`build_windows_firewall_repair_commands` (`:278-305`), +`managed_windows_firewall_rule_name` (`:230-232`), +`firewall_commands` (`:190-223`). A `u16` renders as 1–5 digits; no metacharacter is +representable. `get_existing_managed_windows_firewall_ports` (`:313-331`) builds +`name=Freshell (port )` and passes it as a **single argv element**, not through a +shell — the spaces and parens are inert. + +The `linux-ufw` / `linux-firewalld` / `macos` outputs from `firewall_commands` are +`sudo …` strings, but they are returned as **data** in the status JSON for the user to +copy-paste (`network.rs:163-169, 207`) and are never executed. Confirmed: no non-test +caller executes them. + +### 3f. Answer to "can ANY request byte reach a shell/PowerShell string unescaped?" + +**Today: no.** There is no request path that reaches any command builder. The one live +subprocess path (`resolve_live_network_facts`, `network.rs:225-256`) takes **no request +input at all** — `detect_firewall`, `detect_lan_ips_via_ipconfig` +(`network.rs:371-377`), and `detect_lan_ips_from_windows_interfaces` +(`network.rs:459-472`) run fixed argv with a hardcoded `WINDOWS_IP_PROBE` constant. + +**Post-wiring: yes, via `wsl_ip`, unless NET08-A is fixed first.** That is the single +seam to close. + +--- + +## 4. TOKEN PROTOCOL — one-time, action-bound, constant-time, consumed + +**Status: MIXED. Correct on one-time/action-bound; one genuine defect (non-constant-time +comparison); consumption-on-failure differs from the brief's expectation.** + +The gate is `ConfirmationGate` (`elevated.rs:136-266`), currently **unconstructed outside +its own tests**. + +**One-time — PASS.** `consume_confirmation` (`:177-188`) sets `self.current = None` on +match, so a replay falls to the mismatch branch and re-issues instead of spawning. +Asserted by `phase2_matching_token_spawns_via_injected_fake` (`:408`). + +**Action-bound — PASS.** `matches_confirmation` (`:168-173`) requires +`c.token == t && c.action == action`. A `windows-repair` token presented for +`wsl2-disable` fails, falls into the phase-1 branch at `:242-244`, and returns +`Issued` **without spawning**. Cross-action reuse is rejected. + +**Replay — PASS.** Covered above; wrong-token also proven no-spawn by +`confirm_with_wrong_token_reissues_and_does_not_spawn` (`:411-431`, asserts +`runner.call_count() == 0`). + +### FINDING NET08-C — confirmation token compared with `==`, not constant-time + +**Severity: LOW.** + +**Location:** `crates/freshell-platform/src/elevated.rs:170` (and the same pattern at +`:194` in `consume_current_confirmation`). + +```rust +(Some(c), Some(t)) => c.token == t && c.action == action, // :170 — short-circuits +``` + +Rust's `str` equality short-circuits on the first differing byte, making this +timing-variable. This is a real inconsistency: the *auth* token is carefully compared +with `freshell_api::constant_time_eq` (`boot.rs:705`), and the confirmation token — +which authorizes an **elevated, post-UAC** operation — is not. + +I am rating this LOW rather than higher, honestly: the token is a `randomUUID` (122 bits +of entropy), each failed guess **destroys and re-issues** the token via the +`Issued`/`Reissued` paths, and the remote timing signal across a network is far below the +per-byte delta. It is not practically exploitable. It is still the wrong primitive in a +security-critical comparison, it is a one-line fix, and leaving it invites the pattern to +be copied. Use `freshell_api::constant_time_eq` at both `:170` and `:194`. + +### Consumption on the failure path — deviation from the brief, judged correct + +The brief expects the token "consumed on both success and failure paths". The code does +**not** consume on mismatch: `consume_confirmation` returns `false` and leaves +`self.current` intact, and the caller then *overwrites* it with a fresh token via +`issue_confirmation` (`:243`, `:254`). The net effect is equivalent — the presented +token is invalidated either way, and no stale token survives a failed attempt — while +also preserving the reference's UX (the client immediately receives a usable new token). +I checked whether this enables an oracle: it does not, because the attacker's guess is +discarded regardless of outcome. **Not a finding**, but flagging the intentional +divergence so it is not mistaken for an oversight later. + +--- + +## 5. CONCURRENCY — in-progress lock and TOCTOU + +**Status: PASS for the current single-threaded `&mut self` design; MUST be re-audited +when shared across requests.** + +I specifically looked for a TOCTOU window between the check and the set. There is none +*within* `try_acquire_repair_lock` (`elevated.rs:208-214`): + +```rust +pub fn try_acquire_repair_lock(&mut self) -> bool { + if self.repair_in_flight { return false; } + self.repair_in_flight = true; + true +} +``` + +Check and set are both under the same `&mut self` exclusive borrow, so Rust's borrow +checker guarantees no interleaving — this is atomic by construction, not by discipline. + +The early-return pre-check at `:237-239` **is** a classic TOCTOU shape (read +`repair_in_flight`, act later), but it is correctly backstopped: the authoritative +acquisition at `:247-249` re-checks and returns `Locked` if the race was lost, and the +token is only consumed at `:252` **after** the lock is held. Ordering is right: +lock → consume → spawn. Lock release on the re-issue path (`:253`) prevents a +deadlock-by-abandoned-lock. + +**Requirement for wiring (this is the part that will actually bite):** `&mut self` +means the gate must live behind a `Mutex`/`RwLock` in shared axum state. If a future +implementation takes the lock, drops the guard, and *then* calls `request_elevation`, the +`&mut`-derived atomicity is lost and two concurrent confirmed requests could both spawn +elevated commands. The guard must be held across the whole `request_elevation` call. +A `tokio::sync::Mutex` with the guard held for the duration is the +correct shape. I could not audit this because no wiring exists. + +I also note the release path is not panic-safe: `request_elevation` releases the lock +manually at `:253` / `:261`. If `spawn_elevated_powershell` panics, the lock leaks and +every subsequent privileged op returns 409 forever (an availability bug, not a security +bypass). An RAII guard would be the idiomatic fix. + +--- + +## 6. SECRET HYGIENE (NET-03) — auth token / share-URL token in logs + +**Status: PASS for the live configuration. One conditional gap documented.** + +The `accessUrl` in the status response embeds the live `AUTH_TOKEN` +(`network.rs:192` → `access_url`, `crates/freshell-platform/src/network.rs:245-260`). +That is by design — it is the shareable URL, delivered to an already-authenticated +caller over the response body. The question is whether it leaks into *logs*. + +Three defenses, checked in order: + +1. **Writer-level scrub (`logging.rs:181-201`), applied to every line before any byte + reaches disk** (`RotatingWriter::write_line`, `:288-296`). It replaces the verbatim + secret, then redacts any `"*token*"` JSON field, `"cookie"` fields, and raw + `Cookie:`/`Set-Cookie:` headers. The design point — the scrub is a property of the + writer, not of the call site — is the right architecture: no handler can leak by + forgetting. +2. **Route sanitization (`logging.rs:460-479`)** strips `?token=` from the logged route + before it reaches the formatter. +3. **Diag redaction (`diag.rs:193-214`, `is_secret_key` at `:218-228`)** redacts + `token`/`apikey`/`secret`/`password`/`credential`/`cookie`/`authorization` keys at any + depth, plus marker-tagged fields. + +`crates/freshell-server/src/network.rs` emits **no log statements at all** (no +`tracing::`/`info!`/`debug!`), so `accessUrl` never reaches a logger from the network +module in the first place. + +### INFO-2 — percent-encoding can defeat the verbatim-secret scrub (conditional, does not apply to this host) + +**Severity: INFORMATIONAL.** + +**Location:** `crates/freshell-server/src/logging.rs:184` interacting with +`crates/freshell-platform/src/network.rs:258`. + +`scrub` replaces the secret **verbatim** (`out.replace(secret, ...)`), but `access_url` +writes the token **percent-encoded** (`encode_uri_component`, `network.rs:227-241`). If a +token contains any character outside `A-Za-z0-9-_.!~*'()`, the encoded form differs from +the raw form and the verbatim replace misses. The `"*token*"`-field regex does not +rescue it either, because `accessUrl` is not a token-named key — the secret sits inside +a **value** under a key named `accessUrl`. + +I reproduced the two cases exactly: + +``` +token = "a b/c+tok" -> logged: "accessUrl":"http://…/?token=a%20b%2Fc%2Btok" [NOT redacted] +token = "6df03d3ed04…" -> logged: "accessUrl":"http://…/?token=***REDACTED***" [redacted] +``` + +**Why this is informational and not a finding:** the live `AUTH_TOKEN` in `.env` is +64 hex characters (verified: `len=64`, `hex_only=1`). Hex is entirely within the +unreserved set, so encoding is the identity function and the verbatim scrub matches. The +Tauri-generated token is also hex (`crates/freshell-tauri/src/server.rs:164`). So there +is **no live leak**. The gap only opens if someone sets a token containing a reserved +character — and nothing enforces that they can't. + +**Recommended hardening:** in `scrub`, also replace `encode_uri_component(secret)` +alongside the verbatim secret, and/or add `accessurl` to a URL-bearing key regex that +strips `token=` from values. Cheap, and it removes the dependency on an undocumented +invariant about token alphabets. + +--- + +## 7. EXECUTION GUARD — Windows mutations structurally unreachable + +**Status: PASS. This is the strongest control in the audited surface, and it is what +downgrades NET08-A/B from HIGH to MEDIUM/LOW.** + +Three independent reasons a mutating Windows command cannot run on this host: + +1. **No caller.** `spawn_elevated_powershell`, `request_elevation`, + `build_port_forwarding_script`, `build_firewall_only_script`, + `build_port_forwarding_teardown_script`, and all three + `build_windows_firewall_*_commands` have **zero non-test callers** across `crates/`. + The only non-test references are `pub use` re-exports (`lib.rs:68,81`). Verified by + exhaustive grep per-symbol. +2. **No route.** Section 0 — nothing HTTP-reachable dispatches to them. +3. **No runner.** The only `StdCommandRunner` instantiation in the network path is + `network.rs:228`, feeding `detect_firewall` + the LAN-IP probes. Every one of those is + read-only (`netsh … show`, `ufw status`, `ipconfig.exe`, a fixed-string + `powershell -NoProfile -NonInteractive -Command `). Every mutating builder is + exercised **only** through `FakeCommandRunner`. + +Additionally, `StdCommandRunner::run` (`lib.rs:314-324`) uses `Command::new(cmd).args(...)` +with `stdin(Stdio::null())` — argv, never a shell — and a 5s kill-on-timeout, so even the +read-only probes cannot hang or be shell-injected. + +`ConfirmationGate` is never constructed outside tests, so even the confirmation state +machine is inert. + +--- + +## Findings summary + +| ID | Severity | Location | Summary | +|---|---|---|---| +| NET08-A | **MEDIUM** (HIGH once wired) | `freshell-platform/src/port_forward.rs:338` | `wsl_ip` interpolated into the elevated PowerShell script with no validation; `;`-injection PoC confirmed.

Not exploitable; will not be inherited by new routes. | +| INFO-2 | Info | `freshell-server/src/logging.rs:184` | Verbatim-secret scrub misses percent-encoded tokens in `accessUrl`. No live leak — the live token is 64-char hex. | + +**High/critical findings: 0.** + +--- + +## Verdict and the caveat that matters + +Zero high/critical findings **against the code that exists**. The auth gate is correctly +ordered and constant-time, hostile hosts are rejected by a closed enum, the PowerShell +quoting primitive is correct, the token gate is one-time and action-bound, the lock is +atomic by construction, and mutating Windows commands are unreachable three ways over. + +But I want to be direct rather than reassuring: **this audit largely certifies absence.** +The four mutating routes named in the brief do not exist. The "PASS" on execution-guard, +concurrency-under-load, and command-construction-from-request-input all rest on +`there is no caller` — which is a real and effective control today, and evaporates the +moment the next slice lands. + +Three things must happen before this surface faces an untrusted LAN: + +1. **Fix NET08-A/B first, before wiring.** Change the builder signatures to take a + validated `Ipv4Addr` newtype so unvalidated strings become a compile error. Fixing + this while it is unreachable costs one refactor; fixing it after wiring is an + incident. +2. **Fix NET08-C** (two-line change to `constant_time_eq`) so the pattern is not copied. +3. **Re-audit mandatorily** once `configure` / `disable-remote-access` / + `configure-firewall` / `lan-info` exist — with specific attention to per-route auth + ordering (prefer a middleware layer over four hand-written checks), the + `Mutex` guard being held across the whole `request_elevation` call, + and RAII lock release. + +--- + +### Audit hygiene + +- The PoC test file `crates/freshell-platform/tests/tmp_audit_poc.rs` was created, + executed (4/4 passing, output quoted above), and **deleted**. `git status` shows no new + tracked or untracked files beyond the pre-existing plan docs and this report. +- `cargo test -p freshell-platform` passes. +- No server was restarted; no build overwrote `dist/`.

The reference reads the store on every call + (`network-manager.ts:283`: `await this.configStore.getSettings()`). → must take + `SettingsStore` (which `settings_store.rs` already exposes as a cheap-clone live handle). +2. **`effective_host` is frozen at boot** (`main.rs:706`: `Arc::new(bind_host.clone())`). + The reference derives it from the **live** `server.address()` every call + (`network-manager.ts:290-301`). After a rebind, a frozen value is a lie. → must be live + shared state written by the rebind path. +3. **`facts: OnceCell` caches LAN IPs + firewall for the process lifetime.** The reference + invalidates both on `configure` (`network-manager.ts:418-419`: + `this.firewallInfo = null; await this.refreshLanIpsAsync()`) and exposes + `resetFirewallCache()` (`:530-532`).

Also runs the NET-08 negative matrix (missing auth 401, malformed body 400, arbitrary-host rejection, injection strings never reaching a runner, token replay + concurrent-op 409), kills everything it started, exits 0 only if all pass.\n\nFor each slice list files to touch, TS file:line anchors, acceptance criteria, and which NET items it evidences. Explicitly mark NET-04/05/07 live-effects as HOST-BLOCKED (deferred-with-evidence).

This workspace override shadows the cached bundle skill (first-match-wins) and adds the guardrails proposed in .discovery/code-review-skill-hardening.md (R2): - Phase 0 "Verify the Target": parse $ARGUMENTS for an explicit repo path and expected branch; echo `git rev-parse --show-toplevel`, the current branch, and `git status --porcelain`; REFUSE (report-only, zero edits, no review agents) on branch mismatch, or when no explicit target was given and the cwd repo is on main/master with uncommitted changes the session cannot attribute to itself. - Phase 1: the incoherent fork fallback ("files you edited earlier in this conversation" — always empty in a fork) is replaced with: review files named in $ARGUMENTS, else report "nothing to review" and stop. - Phase 3: fixes are applied ONLY when Phase 0 verified the target; otherwise findings go to a report file with ZERO edits. Invariant: never write into a dirty tree whose changes you cannot attribute. The skill still works as a fork skill when correctly targeted (explicit path + matching branch in $ARGUMENTS).

In a ≥5-codex-tab restore storm, tabs 3+ die visibly. The doc comment at `:453` records this as "D-C-REVISIT — RESOLVED": fail-fast was chosen to prevent ~226s plan-hold stacking.

A restore-create that fails **before a PTY exists** (F1, F2, spawn error) emits no CrashEvent and is invisible to the hub.

The through-line is the **D-GATE-SOFT precedent**: *degrade, never kill* — extended from "the gate may not kill a live pane" to "contention may not kill a restore." + +### P1 — Move codex planning OUT of the spawn-gate permit scope (fixes F2) + +Restore path: in `spawn_gated_restore_create` (`create_gate.rs:72`), before `state.spawn_gate.acquire`, run a new **prepare phase**: + +```rust +// crates/freshell-ws/src/terminal.rs (new seam, extracted from handle_create) +pub(crate) struct PreparedLaunch { + pub resume_session_id: Option, // sessionRef-first derivation, terminal.rs:1667-1682 + pub codex_launch: Option, +} +pub(crate) async fn prepare_launch( + create: &TerminalCreate, state: &WsState, +) -> Result; +``` + +`handle_create` gains an `Option` parameter: `Some` on the restore path (skip inline planning), `None` on the interactive path (plan inline, exactly today's behavior — interactive creates don't ride `spawn_gated_restore_create` and a single interactive codex create holding its permit during planning is not the storm problem). + +**Invariant change to handle:** today "at gate rejection nothing has been materialized" (`create_gate.rs:88-93`). With pre-planning, a `Cancelled`/rejected/shutdown exit after prepare holds a live sidecar+proxy. Every early-exit arm in `spawn_gated_restore_create` must discard the prepared launch (sidecar teardown — reuse the failed-spawn cleanup that `handle_create`'s own error arm already performs). This is a small, enumerable set: the 4 early returns at `:76-86, :87-107, :111-120, :125-137`. + +Effect: permits are held only for PTY-spawn→settle (fast, mode-uniform). **Cross-mode starvation is eliminated structurally** — shell/claude restores no longer queue behind codex planning at all. + +### P2 — Plan budget: queue for restore class, don't die (fixes F1) + +Add a launch class to the manager API: + +```rust +// crates/freshell-codex/src/launch_lifecycle.rs +#[derive(Clone, Copy, PartialEq)] +pub enum LaunchClass { Interactive, Restore } + +pub async fn plan_create_with_retry( + &self, input: &CodexLaunchPlanInput<'_>, attempts: u32, class: LaunchClass, +) -> Result +``` + +- `Restore`: acquire the semaphore with **no wall-clock death**. Wait is bounded structurally, not temporally: `queue_depth × per-plan-bound`, where the per-plan bound already exists (the planner's own attempt budget). Waiting is cancel-aware (select against the caller's `cancel_rx`, threaded down from `spawn_gated_restore_create` — disconnect/shutdown drains the queue, extending T11 semantics). +- `Interactive`: keep today's 30s fail-fast (a human is actively waiting; loud-at-30s for an interactive create is defensible, and the REST `/api/tabs` door — `crates/freshell-freshagent/src/terminal_tabs.rs` codex branch — is interactive by construction). +- Concurrency stays **2** (serialization is the point; each plan is seconds when healthy). Add a bounded plan-queue cap (default 64, matching the spawn gate; env `FRESHELL_CODEX_PLAN_QUEUE_CAP`) — overflow maps to `RATE_LIMITED` (client ladder absorbs), the true backpressure backstop. +- Emit queue-position/phase notifications via a progress callback (`P3`) on enqueue and on acquire. + +Restore storms are **known-finite** work: N panes existed before the bounce, N restores arrive, the queue drains N. There is no unbounded-arrival regime that would justify timeout death; a genuinely wedged planner surfaces per-plan (its own attempt budget → T4/T6), not via queue starvation. + +### P3 — Progress protocol + client placeholder (fixes F4, T5) + +**New server→client frame** (additive; unknown types are ignored by the frozen client, so protocol-safe): + +``` +terminal.restoreProgress { + requestId: string, // the create's requestId — the terminal may not exist yet + phase: 'queued' | 'planning' | 'spawning', + queuePosition?: number, // plan-queue position when phase='queued' + at: string, +} +``` + +Why a new frame and not `terminal.meta.updated`: meta frames are keyed by a *registered terminal*; during queueing/planning no registry row exists. The natural key is the create `requestId`, which the client already correlates (dedupe ladder). Rejected alternative: overloading the auto-resume recovering frame — wrong lifecycle (that lane is keyed by a crashed terminal that *existed*). + +**Terminal states of the sequence:** `terminal.created` (success — clears placeholder, exactly as today) or `error{code, class}` (only after §3's disposition allows it). + +**Wire taxonomy fix (T1/T2/T4 vs T6 conflation):** add an optional discriminator to the create-error frame: `errorClass: 'contention' | 'provider' | 'artifact' | 'identity'`. Under the full design, `contention`-class errors are never *sent* for restore creates (absorbed by P1/P2); the field exists so the client can render any residual/interactive case as "still trying / retry" instead of a dead-pane card, and so tests can pin the mandate ("no frame with `errorClass:'contention'` during a storm"). + +**Client** (`src/store/terminalLifecycleSlice.ts`, `src/components/TerminalView.tsx`, `src/lib/pane-reconcile.ts`): +- New pane transient state `restorePending {phase, queuePosition}` driven by `terminal.restoreProgress` — mirror the existing `recordAutoResumeRecovering` pattern (`terminalLifecycleSlice.ts:60`). +- Placeholder render: "Resuming… (queued, position n)" / "Resuming… (starting codex)" — spinner, not banner. +- `[Restore failed]` banner / `restoreError` card **only** on a terminal error frame whose class is unanticipatable (or `errorClass` absent + retries exhausted). `buildRestoreError` classes (`durable_artifact_missing`, `missing_canonical_identity`, `provider_runtime_failed`, `dead_live_handle`) are already the right unanticipatable vocabulary — they stay. + +### P4 — Retry with backoff: the auto-resume hub owns it (fixes F3) + +**Single owner: extend the existing hub.** A separate restore-retry ledger would be a second writer over the same pane-lifecycle state — rejected on the single-writer discipline established by the identity work. + +- Widen the hub channel from `CrashEvent` to: + +```rust +pub enum ResumeEvent { + Crash(CrashEvent), // today's lane, unchanged + RestoreFailed { // new: create failed pre-PTY + create: Box, // full payload — the hub can re-drive it + create_request_id: String, + error_class: RestoreErrorClass, // from the taxonomy + conn: ConnHandle, // sink + cancel_rx for re-drive & frames + }, +} +``` + +- Emission point: the failure arms of `spawn_gated_restore_create`/`handle_create` for restore-class creates, `error_class ∈ {contention, transient}` only (T6/T7/T8 go loud immediately — deterministic failures don't retry). +- Hub `decide()` gains a restore arm **reusing the existing discipline**: delays `[2s, 10s]` (`AUTO_RESUME_DEFAULT_DELAYS_MS`), history keyed by `create_request_id` (`ResumeHistory` is already keyed that way, `auto_resume.rs:89-97`), and — critically — the **same flap-breaker cycle window** (`:30-38`): restore-retries and crash-resumes share one bounded resurrection budget, so the combined loop can never be infinite-and-silent. Exhaustion → loud `restoreError` with the *original* error class + the existing settle frame, honoring bounded-and-loud. +- Re-drive path: after backoff, feed the stored `TerminalCreate` back through `spawn_gated_restore_create` (the hub's respawn seam already shares `plan_codex_managed_launch`, `terminal.rs:2011-2013`). Dedupe: mint a derived requestId suffix (the original was cleared via `clear_if_in_flight`, `create_gate.rs:84,105,167`) or reuse the original — decide at implementation; the dedupe map semantics at `create_dedupe.rs` support either. +- With P1+P2 absorbing contention, this lane handles only *residual transients* (T4). It is defense-in-depth, not the primary mechanism — which is why it is a later slice. + +### Fairness & ordering (considered, resolved simply) + +- **Per-mode fairness:** achieved structurally by P1 (permits only cover fast PTY spawns) — no weighted scheduler needed. +- **FIFO vs priority:** server stays FIFO. Visible/focused-tabs-first is legitimately a *client send-order* concern — the client already controls the order it issues restore-creates; if wanted, reorder there (zero server change). Rejected: server-side priority queue — adds a scheduler abstraction with no server-visible signal for "focused". + +--- + +## 5.

Alternatives considered + +1. **Env-knob band-aid** (`FRESHELL_SPAWN_GATE_TIMEOUT_MS=60000`, concurrency 6 — the pre-bounce checklist): treats symptoms; codex planning still pins permits, 30s plan death still fires at tab 3+, still no progress UX. Kept only as the operational escape hatch until Slice 1 lands. +2. **Raise plan concurrency (2→N):** trades queue death for memory/CPU stampede of N simultaneous sidecar spawns — the exact ~226s stacking D-C-REVISIT feared. Serialization + queue + progress is strictly better. +3. **Client-only retry** (extend the 2s ladder to `PTY_SPAWN_FAILED`): retries T6 (binary missing) forever or needs the taxonomy anyway; blind to queue state; frozen-client constraint makes iteration slow. Server owns truth; rejected as primary (the existing `RATE_LIMITED` ladder stays as-is). +4. **Separate restore-retry ledger:** second writer over pane lifecycle; violates single-writer; rejected (§P4). +5. **Timeout-with-longer-timeout** (30s→120s plan wait): any fixed wall-clock death loses to a large-enough storm; structural bound (queue-depth × per-plan budget) is the honest bound. Rejected. +6. **Overload `terminal.meta.updated` for progress:** no registry row exists yet; wrong key. Rejected (§P3). +7. **Server-side priority scheduling:** no signal for focus server-side; client send-order achieves it free. Rejected. + +--- + +## 7. Staged implementation plan + +Slices sized for the-usual (worktree, plan→implement→review per slice). **S1 is the pre-bounce minimal patch**; S2–S4 complete the mandate. + +### Slice 1 — Absorb contention, server-only (pre-bounce; small, no protocol change) + +*The user never sees T1/T2 die again; UX during the wait is today's pending state.* + +- `crates/freshell-ws/src/terminal.rs`: extract `prepare_launch` (resume-session-id derivation + `plan_codex_managed_launch`) from `handle_create`; `handle_create` accepts `Option`. +- `crates/freshell-ws/src/create_gate.rs`: call `prepare_launch` before `spawn_gate.acquire`; discard prepared launch in all 4 early-exit arms; restore-class gate wait becomes cancel-aware-unbounded (drop the 10s death for this path only — interactive creates keep `spawn_timeout_ms`). +- `crates/freshell-codex/src/launch_lifecycle.rs`: `LaunchClass` param; restore class queues on the semaphore (cancel-aware) instead of the 30s timeout; plan-queue cap + `RATE_LIMITED` overflow mapping; update the D-C-REVISIT comment block (`:453-458`) to record the supersession. +- `crates/freshell-freshagent/src/terminal_tabs.rs`: pass `LaunchClass::Interactive` (behavior unchanged). +- Tests: unit (budget queue drains N>2 without error via `with_plan_budget` DI; prepared-launch discard on each early exit; gate wait cancels on disconnect); integration restore-storm (§8). + +### Slice 2 — Progress protocol + client placeholder + +- `crates/freshell-protocol/src/server_messages.rs` + `shared/ws-protocol.ts`: `terminal.restoreProgress`, `errorClass` field. +- Emission: plan-queue enqueue/acquire (P2 callback), gate enqueue, PTY-spawn start. +- Client: `terminalLifecycleSlice.ts` (`recordRestoreProgress`, cleared by `terminal.created`/error), `TerminalView.tsx` placeholder render, `pane-reconcile.ts` error-class gating of the `restoreError` card. + +### Slice 3 — Hub-owned retry (defense-in-depth) + +- `crates/freshell-ws/src/auto_resume.rs`: `ResumeEvent` enum, restore arm in `decide()` sharing delays + flap-breaker cycles; re-drive via `spawn_gated_restore_create`; loud settle on exhaustion carrying original class. +- Emission from the residual-transient failure arms only. + +### Slice 4 — Records + hardening + +- `DEVIATIONS.md`: close/annotate D-C-REVISIT (supersede fail-fast), record the A18 sharpening and the A14 evidence (§9). +- e2e: extend `codex_managed_launch_e2e.rs` with a storm phase (fake runtime); client tests for placeholder/banner gating. +- Optional: fold in the resume-button branch as the manual recovery affordance for the loud cases (§9.4). + +--- + +## 8.

Interactions & records + +1. **D-GATE-SOFT:** this design is its generalization — the gate never kills a live pane; now contention never kills a restore. Cite it in the S1 commit. +2. **A14 / D-C-REVISIT** (`launch_lifecycle.rs:453`): the 2/30s fail-fast was explicitly revisit-when-evidence. The S5-flip bounce analysis **is** the evidence (tabs 3+ die at ≥5 codex tabs). S1 supersedes the fail-fast half (restore class) while keeping the half that mattered (concurrency bound 2). Record in DEVIATIONS.md. +3. **Spawn-gate D-C addendum:** permit-hold-from-spawn-to-settle is preserved exactly; only planning moves outside it. The da5d9b5c regression class (early release mid-create) cannot recur — the permit scope still brackets PTY spawn→settle, pinned by `permit_released_only_after_work_completes` (`create_gate.rs:230-249`). +4. **Resume-button branch** (`.worktrees/resume-button`, unmerged): complementary, not competing — it is the *manual* affordance for the loud (unanticipatable) residue; this design shrinks its scope to exactly that residue. Land it after S2 so its button appears only on genuine-failure cards. +5. **Auto-resume flap breaker:** shared cycle window across crash-resumes and restore-retries (P4) keeps the global resurrection budget single and bounded — no new breaker, no second counter. +6. **Frozen-client constraint:** S1 is invisible to the client (strictly fewer error frames). S2's frames are additive. No frozen-client behavior changes required. + +## 10. Open questions (decide at implementation, none block S1) + +1. Retry re-drive requestId: reuse original vs derived suffix (dedupe-map interaction) — S3. +2. Should interactive codex creates also queue-with-progress instead of 30s fail-fast? Defensible either way; deferred until a user report says otherwise (keeps S1 diff minimal). +3. `queuePosition` fidelity: exact position requires a counting queue around the semaphore; "queued" without a number is acceptable for S2 v1.
