 **The session check stops failing for things that are not failures, and a consuming repository can name the gstack it wants without broadcasting to every thread.** Five Captains running gstack on Capy hit the same install friction this week: eight crew-wide "upgrade to <version>" messages since Oct 16, `gstack: fail not-installed` on coordinator machines that run no workflow, `fail pins` from the image's Node while the tests run on the pinned one, reviewers told to "reinstall" when asked to run a workflow, and an environment dump from a broken `/cso` shell line. Each of these is now a product behaviour instead of a crew rule.
 
 ### Added
-- **Project floor** (`floor` row in `gstack-doctor --check`, `lib/doctor-components.ts`, `bin/gstack-doctor-check.sh`): a consuming repository declares the oldest gstack it wants its crew on as `min_gstack_version` in its `.gstack/ship-policy.json` (the key `gstack-ship-queue` already validates; a file holding only that key is valid). The doctor reads it from the project the check runs in: `PASS floor <f> declared by <file>`, `SKIP floor (... declares none)`, or `WARN floor — installed <v> is below the floor <f> ...; fix: <install command>` (`PROJECT_FLOOR_UNMET`). The Capy installer adds `floor=<f> (<file>)` and a `fix:` note to its ok trailer. One commit in the project replaces a message to every thread; the fix on Capy is the install command, which fast-forwards a clean checkout to origin in one step.
+- **Project floor** (`floor` row in `gstack-doctor --check`, `lib/doctor-components.ts`, `bin/gstack-doctor-check.sh`): a consuming repository declares the oldest gstack it wants its crew on as `min_gstack_version` in its `.gstack/ship-policy.json` (the field `gstack-ship-queue` already validates; a file holding only that field is valid).

One commit in the project replaces a message to every thread; the fix on Capy is the install command, which fast-forwards a clean checkout to origin in one step.
 - **`--for none`** (`capy/skill/gstack/scripts/install.sh` wrapper 3, `bin/gstack-capy-install`): a machine that runs no gstack workflow (a coordinator, a liaison, a Captain) prints `gstack: ok not-needed for=none (<notes>)` and exits 0, installing, moving and certifying nothing, with or without a checkout. The bootstrapper answers it itself, so the line is honest for any checkout revision. That ok admits no workflow: no install verdict is written, so a workflow started there is refused with the usual `--for <skill>` fix. `GSTACK_CAPY_MIN_WRAPPER` is 3; older Drive copies keep working and print the owner action.
 - **Review-voice machines upgrade in place** (`bin/gstack-capy-install`): running `--for <skill>` on a machine installed `--for review-voice` says `upgrading the review-voice install in place to --for <skill> (same checkout ...; no second clone)`, applies the project's pins, runs `./setup` and both host profiles, and writes the workflow's verdict over the reviewer's. The admission refusal's fix now says so (`upgrades this checkout in place: ./setup and host profiles, no second clone`) instead of reading like a reinstall.

 - **A gap above the supported minimum is never a hard fail** (`bin/gstack-capy-install`): an install-mode session whose session-start fast-forward was skipped (dirty, diverged or pinned checkout, a live lease, `gstack-upgrade` missing) prints `WARN behind — ... and the session-start upgrade was skipped: <reason>; fix: <command> (UPGRADE_BUSY|UPGRADE_REFUSED|UPGRADE_SKIPPED)` and keeps its ok trailer with `behind=<n> (latest: <ver>); upgrade skipped: <reason> (<CODE>); fix: <command>` notes, exit 0. It used to be `gstack: fail behind`, exit 1. Below the supported minimum the bootstrapper still fails `revision` (`REVISION_BELOW_MINIMUM`).
 - **A Node-only pin mismatch is advisory** (`bin/gstack-doctor-check.sh`): when the project's Node pin is unmet by the Node on PATH while every Bun pin is met, `pins` is `WARN pins — ... (node pin only; bun pins pass); fix: ... (PROJECT_NODE_PIN_UNMET)` and the trailer stays ok. gstack runs on Bun and the project's tests choose their Node (nvm, the CI matrix). A Bun pin that is unmet stays `FAIL pins` (`PROJECT_PIN_MISMATCH`).
 - **WARN rows print their action as given** (`_dc_row`): `owner action: ...` for the Capy skill copy, `fix: ...` for the floor, a skipped upgrade and a Node pin, so a lane knows which WARNs it can clear itself.
+- **A Drive copy below the wrapper minimum is a WARN in a direct run too** (`bin/gstack-doctor-check.sh`): with no bootstrapper provenance (`bin/gstack-upgrade`'s installer run, a direct `gstack-doctor --check`), every Drive copy at a bootstrapper revision below `GSTACK_CAPY_MIN_WRAPPER` is `WARN wrapper — every Capy skill copy is below the minimum wrapper 3 (it still works): ...` with the owner action and an ok trailer; only a pre-bootstrapper copy (no `GSTACK_CAPY_WRAPPER=` line) still fails. Found by /ship's red team: raising the minimum to 3 would otherwise have failed every direct run on a machine whose Drive copy is the deployed wrapper 2 until the owner recopied the skill.
+- **A `--for none` session never self-upgrades** (`bin/gstack-capy-session`): an older bootstrapper (wrapper 1 or 2) hands `--for none` to the session in install mode; the session now treats it like `--check` (reports `behind=`, moves nothing) before the installer prints `ok not-needed`. Wrapper 3 answers `--for none` before the session. The session's header comment describes the `WARN behind` outcome (it said `fail behind`).
 - **/cso** (`cso/SKILL.md.tmpl`): the always-loaded startup block gains two rules. Environment hygiene: prerequisite checks read a variable as set or unset only, and `env`, `printenv`, `set -x`, a bare `set` or `export`, `export $(...)` and `echo "$NAME"` never appear in a tool fence. Tooling errors fail loudly: a non-zero exit with no helper status is retried at most twice (5 s, 30 s) and then ends **not assessed** for whatever the helper never recorded, quoting the command, exit code and stderr tail; never a quiet partial, never another review offered as the missing coverage.
 - **Capy skill and docs** (`capy/skill/gstack/SKILL.md`, `docs/capy-install.md`): the session-start steps cover `--for none`, `floor=`, `behind=` as informational, the Node WARN and the in-place review-voice upgrade; run directories and scratch on Capy live under `~/.capy/work/<name>`, never `/tmp`, which Capy wipes when a machine sleeps.
 - **Result codes** (`lib/result-codes-capy.ts`): `PROJECT_FLOOR_UNMET`, `PROJECT_NODE_PIN_UNMET` and `UPGRADE_SKIPPED`, each with a `docs/troubleshooting.md` anchor.

 ### Tests
 - `test/gstack-doctor.test.ts`: the `floor` row's four outcomes (absent file, null key, met, unmet with the wrapper fix and without it) and the Node-only WARN beside a Bun-plus-Node FAIL; every required-row list gains `floor`.
 - `test/gstack-capy-install.test.ts`: a skipped session-start upgrade is an ok trailer with the `upgrade skipped` note and a `WARN behind` row (replacing the `fail behind` pin); a `WARN floor` row becomes the `floor=` and `fix:` notes, with one `fix:` when `behind=` is also present; `--for none` with and without a checkout; a review-voice verdict upgraded in place by `--for autoplan` (setup runs, the verdict becomes the workflow's).
-- `test/capy-skill-wrapper.test.ts`: `--for none` through the bootstrapper (checkout present, install mode, no checkout), wrapper 3 in the handover.
+- `test/capy-skill-wrapper.test.ts`: `--for none` through the bootstrapper (checkout present, install mode, no checkout), wrapper 3 in the handover; a wrapper-2 handover of `--for none` in install mode leaves HEAD where it was.
+- `test/gstack-doctor.test.ts`: a direct run with every Drive copy a bootstrapper below the minimum is a WARN with an ok trailer, and a pre-bootstrapper copy beside it keeps the FAIL. `test/gstack-capy-install.test.ts`: an unknown skip code collapses to `UPGRADE_SKIPPED` with its anchor; the in-place upgrade message is silent for a same-profile rerun, `--check` and a second review-voice install.
 - `test/helpers/carve-guards.ts`: the /cso skeleton pin moves to 18,900 (measured 18,843) for the two startup paragraphs; `test/fixtures/context-budget.json` pins `capy/skill/gstack` and `cso` at their new eager sizes.

 Resolve `scripts/install.sh` relative to this SKILL.md, not the working repository. It is a frozen bootstrapper: it prints `gstack-capy-skill: wrapper <n> (<path>)` first, learns the supported minimum from gstack's remote, and hands over to the checkout's own wrapper (`bin/gstack-capy-session`).

Read the exit status and grep `^gstack: ` directly; never pipe the check through `tail`, `head` or `grep` alone. `--check` never moves the checkout. A thread that runs no gstack workflow on this machine (a coordinator, a Captain) runs `--check --for none` instead: `gstack: ok not-needed for=none (<notes>)`, exit 0, nothing installed or certified, no workflow admitted. Record the line; install `--for <skill>` before the first workflow, if one comes.

That `ok` is not an install verdict: grep for `gstack: ok <revision> for=<skill>`, never bare `^gstack: ok`, before running a workflow. Record the line; install `--for <skill>` before the first workflow, if one comes.
 2. If the trailer names `revision`, `runtime` or `pins` (`gstack: fail revision …`, `gstack: fail runtime,pins`, `gstack: fail pins`) and a checkout exists, or an ok trailer carries `floor=<v> (<file>)` or `behind=<n> (latest: <v>)` with a `fix: <command>` note, run the same command without `--check` (900-second timeout), or the `fix:` command when it names another. `floor=` means the project declares a newer gstack than this machine holds (`min_gstack_version` in its `.gstack/ship-policy.json`; the `WARN floor` row): run the fix before the first workflow, every time. `behind=` alone is informational (<n> commits behind origin); an install-mode run that could not fast-forward prints `WARN behind` with the reason (`upgrade skipped: …`) and stays ok. Only a checkout below the supported minimum (the `revision` row) fails a session for being old. Report the trailer verbatim, `behind=` and `floor=` included. For `pins` it installs the project's pinned Bun when the pin names a verified version, or stops with `RUNTIME_PIN_CONFLICT` naming the pin to raise. Any clean, unpinned checkout behind origin is fast-forwarded in install mode (below the `GSTACK_MIN_REVISION` floor by the bootstrapper, `gstack-capy-skill: upgraded <old> -> <new>`; above it by the checkout, `SELF_UPGRADE: done <old> -> <new>`), reinstalled and rechecked in one locked step. A pinned (`--revision`, detached), dirty or diverged checkout, or one another live session holds a lease on (`UPGRADE_BUSY`), is never moved: the trailer names the cause and the exact commands (above the floor it stays ok with `WARN behind` after `SELF_UPGRADE: skipped (<reason>)`, carrying `UPGRADE_BUSY` or `UPGRADE_REFUSED`). A lease whose pid was reused after a wake is reclaimed on its own. `GSTACK_CAPY_AUTO_UPGRADE=0` disables every fast-forward, `GSTACK_CAPY_SELF_UPGRADE=off` only the above-floor one.
 3. If the trailer is `gstack: fail not-installed …` and this session runs no gstack workflow, record that line and continue; nothing is installed. Install right before the first workflow with `bash scripts/install.sh --for <skill>` (about 30 s cold: clone, a SHA-256-verified Bun when none installed fits, both host profiles without Chromium, and a `~/.local/bin/bun` shim so fresh shells get the recorded Bun).
 4. Any other `FAIL` row carries a `fix:` command and a reason code with a troubleshooting anchor; run the fix, then `--check` again. `SKIP codex-cli (optional; …)`, `SKIP browser (lazy; …)`, `SKIP pins (planning-only; …)`, `SKIP pins (helper runtime; …)` and `SKIP floor (…)` are not failures. `WARN pins … (node pin only; bun pins pass)` is not one either: the Node on PATH misses the project's pin while Bun is right; run its fix only when this machine will run the project's tests.
