 Open Pstack lands on green: Mergify merges a ready PR to main once verify and exact-head live-gate pass and no review thread is unresolved, and a workflow resolves Unfret's own threads. A PR that touches `.github/` or the Mergify config also waits for Unfret, and workflow changes require operator queueing.
 This port applies the Cursor → Claude Code substitutions in skill bodies. Earlier drafts left them flagged; this revision resolves them. A later pass added a Codex build that shares the same skills; see [Codex port](#codex-port) below.
 
+## Unreleased
+
+**Muse Wonder Full 1.0 lanes.** The model catalog registers `muse:muse-wonder-full-1.0` as an optional family with efforts `low` to `max` and a default of `max`, so `/setup-pstack` can place it in a role or panel. Muse lanes keep the external runner from every parent, and a Muse writer still needs `muse writer sandbox: full-access`. The Muse preflight also passes a signed-in `muse usage` that prints `No usage data (server_sent_no_usage)`, with the evidence `subscription-no-usage-data`; measured with Muse Code 1.4.14, that output proves the login, and the model call still checks the allowance. Default roles and panels are unchanged.

 ## 1.21.0 adds Grok as a parent harness
 
 Open Pstack 1.21.0 keeps the Cursor pstack 0.15.36 sync. Default roles and panels are unchanged.

+- Measured with Muse Code 1.4.14 on macOS. Every flag in the argv is in the recorded `muse --help` and `muse exec --help`. A lane runs `exec --json --model <model> --prompt-file <prompt> --workspace <cwd> --worktree off --approval-mode never --approval-judge off` with web tools, reminders, `request_user_input`, foreign personal context and the session log turned off. The effort is `--reasoning-effort <effort>`, omitted for `default`; Muse also accepts `none` and `minimal`, which the runner does not offer. The parent owns the worktree, so Muse creates none. The registered family is Muse Wonder Full 1.0; a lane may also name any other Muse catalog model, such as `muse-spark-1.3`, as an unregistered pair.
 - A read-only lane adds `--disable-write --disable-shell`. The file-reading tools remain, and a write request fails with `writes are disabled for this session`.
 - No Muse writer is confined, so a writer needs the model sheet's opt-in (`isolated-write-full-access`); the runner refuses a bounded `isolated-write` lane before launch. An opted-in writer drops `--disable-write` and `--disable-shell` and keeps Muse's sandbox on. Measured in a linked worktree under the home directory, whose main repository and a sibling directory sat beside it: edits, shell writes and a Python run inside the worktree succeeded. The file tools refused every path outside the workspace (`absolute path is outside the workspace`, `path escapes workspace`) except the system temporary folders. The sandboxed shell failed outside the worktree with `Operation not permitted`, except that it wrote into the main repository's shared `.git`, `/tmp` and `$TMPDIR`. With `--disable-sandbox`, the file tools and the shell wrote into every outside target, so the runner never passes it.
 - With `--approval-mode never --approval-judge off`, a refused tool call returns its error to the model and the run continues. Muse reports `Agent delegation: auto unavailable: workspace is untrusted` on stderr, and the lane never passes `--trust-workspace`, so the workspace's skills and rules do not load.
 - Muse reads `~/.config/muse/settings.json` in every lane. Its `endpoint_transport` key reroutes every lane to another endpoint: on the measured host, a value that another tool wrote sent each lane to a proxy, and every turn failed with `still unauthorized after a token refresh`. The runner does not override it.
 - The environment is the base allowlist plus `META_API_KEY`. The account login is found through `HOME`. `muse login --help` says `META_API_KEY` always takes priority over the account login.
-- The preflight runs `muse usage`. It passes when it exits 0 and starts with `Tier: `, with the fixed evidence `authenticated`, because the output names the subscription tier. It also passes when it exits 0 and starts with `No subscription allowance (api_key)`, with the fixed evidence `api-key`, because `META_API_KEY` is the login and the model call checks access. Exit 1 with `muse usage: not logged in:` is `unauthenticated`/77. Any other output is `child-failed`/70.

The server answered for the subscription, so the login holds and the model call checks access; on that host the model call then returned `API error 429 ... Subscription quota exhausted` as `child-failed`/70, so this output proves the login, not an allowance. Exit 1 with `muse usage: not logged in:` is `unauthenticated`/77. Any other output is `child-failed`/70.
 - The `--json` stream is one envelope per line, dispatched on `payload_type`. The reply is the text of the last `run.terminal.*` event, accepted only when its `terminal` is `completed` and the text is not empty. Another terminal is `child-failed`/70 with its reason, except that `model `<id>` does not exist or you lack access` is `unavailable-model`/69. SIGINT exits 130 and SIGTERM 143, each with no terminal event, which is `cancelled`/130; a stream with no terminal event otherwise is `malformed-output`/65. The session is the `session` stream ID, and usage sums the `run.usage` event's per-model tokens. No cost is reported.
 - `run.model.configured` repeats the requested model, and no event was shown to name a different served model, so the model proof is the pinned argv (`pinned-argv`).
