Since 778c18fb23 the carrier key holds the tokens file's mtime and size.
sys-token-store changed that stat on every inclusion (00_core.yml
touched the file) and on every persisted token, and nothing re-parked a
carrier afterwards. Every later task's fresh worker then rendered the
applications SPOT cold, 30 to 80 s each. On main fea6f31d9f (run
38812964308) seven heavy jobs logged 194 to 287 such tasks and ran out
of the 20400 s budget; the same jobs before 778c18fb23 logged 65 to 83,
all of them real waits.

- 00_core.yml touches the store with modification_time and access_time
  preserved, so it only creates a missing file. In swarm the controller
  sees the store over NFS with attribute caching, and the touch alone
  made the second pass go cold without any write.
- write.yml re-parks the carrier when the persist or the controller
  mirror changed the store. Both run once, so every host that ran the
  include gets the same verdict.
- tasks/utils/setup/role.yml re-parks after every role on every host,
  so hosts that did not run the writing role recover too. Where the
  key still matches this serves the carried payload; measured 0.1 s per
  role in a local compose deploy.
- The tokens file enters the key as the SHA-256 of its content,
  memoised per inode, mtime and size, so a touch no longer changes the
  key. A stat that still matches serves the memo (1.67 us against
  1.41 us for the old stat signature), and a stale stat keeps key and
  YAML cache on the same old content instead of pairing new content
  with an old key.
- applications_carrier opens the tokens file before it computes the
  key, so on the NFS-mounted controller the parked key reflects the
  revalidated attributes rather than a cached stat that changes a
  minute later.

kevinveenbirkenbachandClaude Opus 5 8aea5a9b35 fix(deploy): keep role setup in run_after order across hosts
A per-host `when` on the looped include_tasks made ansible insert the included blocks in host order instead of loop order: whichever host reached an item first decided when that item ran. With the nfs-server host last in the inventory, svc-storage-nfs-client mounted the export before svc-storage-nfs-server had deployed it, and the play died on 'mount.nfs4: Connection refused' (run 31645153977, job 94280126636).

Gating on the include_role instead keeps every host on the same loop, so one block per item is inserted in loop order. This is what cli/build/include emitted before 351b64e2c: the when on the include_role, the flush unconditional behind it.

Reproduced with a four-host probe -- server host last inverts the order, gating one level down restores it. In run 31543714113 'setup svc-storage-nfs-server' ran 3 times; in 31645153977 it never ran.

kevinveenbirkenbachandClaude Opus 5 351b64e2c5 refactor(deploy): resolve role groups at runtime instead of generating task files
`cli build include` generated one tasks/groups/<group>-roles.yml per invokable category during setup, and the stage plays included those files. They were written by the in-container UID, which is why a dedicated clean-container-owned helper had to delete them from inside the container.

The stage plays now loop over lookup('group_roles', <group>) and include tasks/utils/setup/{group,role}.yml directly. ordered_roles() in utils/roles/order.py holds the run_after topological sort the generator used to perform at build time.

utils/roles/stage.py:_group_names() no longer globs the generated files; it reads get_invokable_paths(), the same categories.yml source those files were derived from.

Measured: handlers still flush after every role (ansible-core 2.20.2, three loop items, three separate handler runs), and resolving all 18 groups costs 0.60s cold against 1.4s for the generator.
