Evidence (verified in this investigation) + +All root-cause hypotheses from the forensics were **confirmed**, with one significant refinement (E1). + +**E1 — The recipe never asked for this skill.** `the-usual.yaml` references exactly two skills by +name: `using-git-worktrees` (Step 0, line 333) and `requesting-code-review` (Step 4 final +whole-branch review, line 2129 — a *template-only* skill, reviewer is read-only). The string +`code-review` appears nowhere else as an invocation.

This is a **name-collision misload**: the step-runner, told to +"request a code review," reached for the similarly-named destructive fork skill. The invocation was +`load_skill(skill_name="code-review")` with **no `arguments`** — so `$ARGUMENTS` was empty. + +**E2 — The fork saw nothing but the skill body.** Fork session +`2c2d3fdcff954fa0-3b504f48b07944ad_self` (metadata: parent = the step-runner above): its first user +message is the SKILL.md body verbatim, with the `$ARGUMENTS` slot rendered as +`special attention to: `` ` (empty).

"No managed turn/activity tracking" — **FALSE in effect.** Disk rollout lane delivers turn/activity with sessionId (`2d592afa`, `71dd4830`; hardened `18bc5443` 07-29). It is not the *managed* (proxy) stream, but the user-visible absence the spec describes is gone. +4. "DEV-0008 badges stay absent" — **PARTLY FALSE.** `terminal.meta.updated` is emitted at create time (`terminal.rs:3198-3270,5116`; builder introduced `b9e0c1a3` 2026-07-16 — *pre-dating the spec*, which missed it) and at codex/opencode association (`codex_identity.rs:229`, `opencode_association.rs:172`, since 07-24/26).

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." Instead the design moved to server-authoritative sessionRef: WS derives codex resume sessionRef-first with raw fallback (`136b9e94`; `terminal.rs:1172-1176`), guarded by D7 live-session refusal (`043a9340`), D8 per-sessionRef leases + `SESSION_RESERVED` (`88a33933`), and `SESSION_IDENTITY_MISMATCH` input bounces (`60281e25`). REST still hard-rejects raw codex resume (`terminal_tabs.rs:65,:130`) and EDEV-07 synthesizes sessionRef from canonical legacy ids. "Align to legacy" is no longer the frame — Rust intentionally exceeds legacy here, recorded as EDEVs. + +## F8. S5's assumed substrate in freshell-codex was partially deleted as dead code +`35cf2864` (07-24) removed `default_durability_store_dir` / `DurabilityCandidate` (-114 lines in `freshell-codex/src/durability.rs`); `2a68d027` removed 447 lines of restore-decision machinery from `launch_plan.rs`. The spec's launch_lifecycle note "S5 swaps the recording for the real write" now points at a durability store whose exports no longer exist; the pane-identity ledger (in `freshell-ws`, planned to hoist for P1.13) is the incumbent durable store. + +## F9.

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**.

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/`.

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. That resolution predates the mandate and the flag flip; this spec supersedes it (§9.2). + +### F2 — Restore-creates hold a spawn-gate permit across codex planning + +`crates/freshell-ws/src/create_gate.rs:62-188` (`spawn_gated_restore_create`): the permit is acquired (`:74`, timeout = `create_protect.spawn_timeout_ms`) and held across the **whole** `handle_create` (`:145-164`) — which *includes* codex planning (sidecar spawn + proxy start, seconds each; up to 30s budget wait; 5-attempt initial retry budget). Gate config: **4 permits, 64 queue cap, 10s queue timeout** (`crates/freshell-ws/src/create_limit.rs:47-49`; env knobs `:64-66`). + +Consequence: two codex restores planning = 2 of 4 permits pinned for seconds-to-tens-of-seconds; two more codex restores occupy the remaining permits waiting on the plan budget; **shell/claude/opencode restores queue behind them and die at the 10s timeout** — cross-mode starvation of the cheap by the expensive. + +The permit-hold-across-settle itself is correct and hard-won (the da5d9b5c prior-art bug, `create_gate.rs:39-51`); the defect is *what* is inside the hold, not the hold. + +### F3 — No retry for failed restore-creates + +The auto-resume hub consumes `CrashEvent`s produced by PTY exit hooks only (`crates/freshell-ws/src/auto_resume.rs:12-17, 99-111` — `finish_pty_exit` → `build_pty_exit_hook`). A restore-create that fails **before a PTY exists** (F1, F2, spawn error) emits no CrashEvent and is invisible to the hub. There is no server-side retry; the client's 2s `RATE_LIMITED` ladder (~38s patience, `create_limit.rs:38`, `create_dedupe.rs:364`) retries only `RATE_LIMITED`, not `PTY_SPAWN_FAILED`. The manual resume button is unmerged (`.worktrees/resume-button`). Result: identity survives (ledger row intact) but the pane is dead until the user reopens it from the sidebar. + +### F4 — Client has no "resuming" state + +A pending restore renders nothing meaningful; a failed one renders the `[Restore failed]` banner / `restoreError` card immediately (`TerminalView.tsx:3282`, `src/lib/pane-reconcile.ts:259-262`).

Fixing the taxonomy on the wire is part of the design (§5). + +--- + +## 4. Design + +Four pillars, ordered by leverage. 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).
