- 2026-08-10 17:25:19 — part of check-in [f1ac625093] on branch sub-manifest — control files: registry, provenance opt-in, one scratch prefix, advisory dir
  Tasks 1-5 of the control-file consolidation plan. The checkout root goes from twelve zit-owned names to six live ones; the authoritative-tier container (task 6) and legacy removal (task 7) are deliberately not in this change.
  Registry: control_paths now carries every reserved root name with its tier -- authoritative, advisory, scratch, legacy -- and is the single authority the case table, the extras exclusions and the ignore-glob coverage pin all derive from or test against. A name added without its glob line or case coverage is a test failure, proven by mutation. The pin caught two live gaps on arrival: a crashed update's transaction directory had no ignore-glob line, and a crashed import's staging directory was never reserved at all.
  import-git --provenance: the per-object map and the source ref manifest are now instrumentation, published only on request. The default destination is the repository and its checkout record -- fossil's own shape. Both files are still written and verified in staging every run; without the flag they leave with the raw generation, and the staging manifest check enforces whichever set was chosen.
  Scratch: one prefix. .zit-tmp-txn- (update transactions), .zit-tmp-import- (import staging), .zit-tmp-pack (pack scratch; name only, the truncate-reuse and rewrite-exclusion lock protocol are untouched). One registry prefix row and one glob line cover the tier including names that do not exist yet.
  Advisory: .zit-cache is a directory -- repo (derived-state cache) and vstat (materialization plan), with the tree-checkpoint's member reserved. A legacy cache FILE is served through a read fallback and migrated by the first write via rename through a scratch name: the derivation survives with no bytes copied and no re-derive. Verified on a 66k-file pkgsrc checkout: identical SHA-256 across migration of a 35.8MB cache, fallback reads at parity, no-op update 7.69s vs 7.74s.
  Legacy spellings of every renamed or relocated name stay reserved and ignore-globbed until the removal release. (user: dmestas, size: 43501) [annotate] [blame] [check-ins using]
