feat(workplan): close STATE-WP-0083-T05 — every hub record derives from a file

51 records retired across the fleet; 106 of 121 repositories now noop. Zero
repositories hold a record that no longer derives.

26 real workplans were rescued from wrongful retirement — more than half the
number retired. vergabe-teilnahme (17) predated the convention entirely; nine
further files across five repositories carried no type field, three of them
created by this session's own renames.

Also records the RPF-WP collision this session introduced by numbering from
0001 without checking whether the target prefix was in use.

+**26 real workplans were rescued from wrongful retirement**, more than half the
+number actually retired:
+
+- `vergabe-teilnahme` (17) — a repository predating the convention entirely: no
+  `type:` field anywhere, bare `WP-NNNN` identifiers, no hub identifiers, no
+  registered prefix. The diff showed 16 records to retire; the truth was 17
+  workplans no projection could see.
+- `glas-harness` (3), `binky-control` (2), `rein-aharness` (2), `ops-mason` (1),
+  `rein-openweights` (1) — files carrying no `type:` field at all.
+
+Three of those nine were created *by this session's own renames*, which never
+added a type the files had never had. The pre-flight check — does the forge
+derivation actually see workplans in this repository — is the only reason they
+survived, and it has now caught wrongful retirement three times: `kont-wp-0015`,
+all of `vergabe-teilnahme`, and these nine.
+
+**A collision this session created.** Retiring `railiance-platform` first
+required repairing a fault introduced earlier the same day: the `RAILIANCE-WP`
+migration numbered from `RPF-WP-0001` without checking whether the target prefix
+was in use. It was, and the migration collided at 0018, 0019 and 0020. The fleet
+reset then ran over the colliding files and left mixed records on central —
+`rpf-wp-0018` carried one file's status and another's backing path. The
+displaced files moved to 0025-0027. The source numbering was checked before
+renaming; the target was not.
+
+**Remaining, and not solvable by retirement:** 9 private repositories central
+cannot clone, and 9 identifier collisions that are identity decisions.
