feat(commands): a write that leaves the repo says so before you approve it (M-BUG-41)

The chain observed configuration across repos but presented every write it then
proposed as though it landed where the session stands. STATE named two arms;
measuring found five, and two of them are worse than the two already known:

- implement — the approval prompt named NO path at all, only a count, so a plan
  editing ~/.claude/CLAUDE.md and one editing ./CLAUDE.md produced byte-identical
  prompts.
- rollback — the file list rendered `.claude/settings.json`, a repo-relative
  FORM, while the restore writes to the absolute original. The other arms were
  silent; this one pointed the wrong way.
- fix — paths were visible but unclassified, and --global mixed machine-wide and
  project rows into one unmarked table.

The gate's strength comes from the target's scope class, never from the command
asking: five command-owned policies would drift apart the way five copies of the
lever table did. SCOPE_CLASSES is one source for class, gate, wording and
predicate; templates render `disclosures[]` from the CLI instead of restating
what a class means.

Two orderings in that table are load-bearing, and both were measured:

- plugin-managed before user-scope. Both ~/.claude/config-audit/ and the legacy
  ~/.config-audit/ are live, and every command writes session state there. The
  other order fires the gate on every write ever made and gets it switched off,
  which is worse than no gate.
- user-scope before cross-repo. ~/.claude/.git EXISTS, so a plain .git-upward
  walk answers "another repo" for ~/.claude/CLAUDE.md and silently downgrades
  the strongest gate on the subtraction axis's primary target to disclosure.

disclose is not require-ok: campaign export is cross-repo by design, so the gate
there says so rather than refusing. Distinct from require-target-dir.mjs, which
asks whether a scan ROOT is readable (exit 3) — a different invariant, left
unmerged along with its four inline copies.

Also structural, both found while building this: the hand-maintained GUARDED
list in the unknown-flag sweep now derives its completeness from the directory
(measured complete at 14 of 14 first, so nothing was hiding — but the 15th CLI
would have been swept by nothing); and prose shape-guards use whitespace-
tolerant patterns, after one went red against a command file that did say the
right thing, line-wrapped.

Gated: implement, fix, rollback, plan, campaign export. Suite 1596 -> 1625/0,
frozen v5.0.0 and default-output baselines 0 changed files. No new GAP dimension,
no lever, no finding code — utilization denominators untouched.

+**Write-scope gate (invariant).** Every write target is classified by `scanners/lib/write-scope.mjs` before it reaches an approval surface, and the **scope class decides the gate's strength — never the command asking**. Five command-owned policies would drift apart the way five copies of the lever table did. `SCOPE_CLASSES` is the single source for class, gate (`silent`/`disclose`/`require-ok`), wording and predicate; templates render `disclosures[]` from `write-scope-cli.mjs` rather than restating what a class means. Two orderings in that object are load-bearing and were measured, not reasoned about: `plugin-managed` before `user-scope` (both `~/.claude/config-audit/` and legacy `~/.config-audit/` are live, so the other order fires the gate on every session write and gets it switched off), and `user-scope` before `cross-repo` (`~/.claude/.git` exists, so a plain `.git`-upward walk calls `~/.claude/CLAUDE.md` merely "another repo" and silently downgrades the strongest gate). `disclose` ≠ `require-ok`: `campaign export` is cross-repo *by design*, so tightening it into a refusal breaks the feature. Distinct from the `require-target-dir.mjs` guard, which asks whether a scan **root** is readable (exit 3) — a different invariant, not to be merged.
+
 **Subtraction floor (invariant).** `optimize --subtract` is the only lens that proposes removing config, so `scanners/lib/floor-exclusion.mjs` runs as a deterministic pre-step *before* the judge — a load-bearing block is never a candidate, and that guarantee must not be moved into the agent prompt. Two rules follow from it: (1) **staleness is not a deletion signal** — an outdated version pin inside a floor block is a `drift`/`CA-CML` dead-reference concern; (2) **tier 2 ≠ tier 3** — a compensatory block that keeps earning its place returns, and reporting it as dead weight is wrong even when the label matches. Norwegian keywords need the Unicode boundaries in `subtraction-prefilter.mjs`; JS `\b` is ASCII-only, so `/\bunngå\b/` silently never matches.
