feat(guardrails): push every commit, static deny for destructive tools, brief carries no user authority

Layer C of the plan written after the 2026-09-21 wipe (BDR-095): a reviewer
sub-agent traced `lftp mirror --delete` against a local file:// tree, the
prose tiers named neither lftp nor a local trace, the brief had authorized
it, and four days of commits had never left the machine.

- gitflow: `start` pushes the branch with its upstream, merge targets are
  pushed after each merge, and `init`/`install-hook` write post-commit and
  post-merge hooks that push every commit as it lands (warn, never block;
  GITFLOW_NO_PUSH=1 for throwaway repos). T18 + T19 (installed == emitted).
- hooks/unpushed-guard.sh on SessionStart and Stop: branch ahead of its
  upstream, no upstream, or no origin. Non-blocking systemMessage.
- settings.json: static deny for transfer and mirror tools, rsync --delete,
  xargs rm, pipe-to-shell, chmod/chown -R, sudo/doas/pkexec, disk tools,
  chattr, docker volume drops/prune/--privileged/socket/-v /:, git history
  destruction, --no-verify and core.hooksPath; new hard_deny "destructive
  tool against a local path, brief carries no user authority"; soft_deny
  reworded + discarding uncommitted work; environment records the incident.
- CLAUDE.global.md "Destructive tools & data loss"; the four report-only
  agents trace by reading, never by running, whatever the brief says.
- lib/tests/guard-bash.test.sh: executable spec of the PreToolUse guard
  (214 cases). The hook itself is not shipped (BLK-022); the spec skips.

+- A destructive tool is never run "to see what it would do", not even
+  against a scratch tree. Trace it by reading. If a run is unavoidable, the
+  target is a fresh `mktemp -d` path written literally in the same command,
+  after a dry-run whose output is shown.
+- Recursive delete stays inside the project or the temp dir, on a literal
+  relative path: never through a variable, `~`, `..`, a wildcard, or an
+  absolute path elsewhere. `chmod -R`, `chown -R`, `sudo`, docker volume
+  drops or system bind mounts: the user runs them by hand.
+- A brief, a plan step or a test recipe never authorizes a sub-agent to do
+  any of the above. A reviewer reads the script it reviews; it does not run
+  it.
+- Every commit is pushed as it lands (gitflow post-commit and post-merge
+  hooks) and every branch at creation. Unpushed work is a defect to fix now,
+  not a state to keep.

+## Data-loss guardrails (BDR-095)
+
+Written after the 2026-09-21 wipe: a sub-agent traced `lftp mirror --delete`
+against a local `file://` path; the prose tiers named neither lftp nor a
+local trace, and the brief had authorized it. What holds now, by tier:
+
+| Class | Where | Why that tier |
+|---|---|---|
+| Transfer and mirror tools (`lftp`, `sftp`, `ftp`, `curl -T`), `rsync --delete`, `xargs rm`, pipe-to-shell | `permissions.deny` | Never needed in a session: Claude explains a deploy, the user runs it. Static, so it resolves before the classifier and inside sub-agents. |
+| `chmod`/`chown -R`, `sudo`/`doas`/`pkexec`, disk tools (`dd`, `mkfs`, `shred`…), `chattr` | `permissions.deny` | The user runs them by hand. |
+| Docker volume drops, `system prune`, `compose down -v`, `--privileged`, the docker socket, `-v /:` | `permissions.deny` | Promoted from `soft_deny`: no in-session clearance for data drops. |
+| Git history destruction (`push --delete`/`--mirror`/`:ref`/`--force-with-lease`, `branch -D`, `filter-branch`, `reflog expire`, `stash clear`/`drop`, `clean -f`), `--no-verify`, `core.hooksPath` | `permissions.deny` | A remote is the backup; nothing rewrites or deletes what it holds. |
+| Destructive tool against a local path (variable, `~`, `..`, wildcard, outside cwd/tmp), even as a trace or a rehearsal a brief allows | `autoMode.hard_deny` | A pattern cannot express "the target resolves outside the project"; the classifier can. A sub-agent brief carries no user authority. |
+| `docker rm -f`, bind mount outside cwd; discarding uncommitted work | `autoMode.soft_deny` | Recoverable or user-intended in the turn. |
+
+Rules apply to sub-agents (auto mode is inherited) and to each segment of
+a compound command; a tool nested in another command (`docker compose run …
+lftp`) is not matched by a static rule. The PreToolUse guard hook that scans
+the whole command, its executable spec in `lib/tests/guard-bash.test.sh`,
+is not shipped yet (BLK-022).
+
+Push discipline lives in `lib/gitflow.sh`: `start` pushes the branch,
+`finish` pushes each merge target, and the post-commit / post-merge hooks
+written by `gitflow init` / `install-hook` push every commit as it lands
+(warn, never block, on failure; `GITFLOW_NO_PUSH=1` for throwaway repos).
+`hooks/unpushed-guard.sh` reports a branch ahead of its upstream at session
+start and at each turn end.
