2026-09-09 — adr-2609090717039680 is superseded by adr-2609091248201071, one record for that original alone (maintainer, ruling on iss-2609091155525689 that each record describing the real-dir helper at its pre-consolidation home gets its own successor rather than one record covering both). The mechanism is unchanged and its home moved: `24c2f2e3` consolidated the three `ensureRealDir` copies into `fsutil.EnsureRealDir` / `EnsureRealDirAll`, so `internal/core/history` owns the store's layout and mode and calls the primitive for the create-then-prove step. Rejected: describing the mechanism and naming no symbol, which is the reading under which a fourth copy is a faithful implementation of the record.

• adr-2609090717039680The transcript corpus is a sibling store that creates itself, and the per-repo location is an opt-in pull
• adr-2609091248200336A tool never creates directories in user-owned project space; the store's location binds now and its verbs bind when the store ships
• adr-2609091248201071The transcript corpus is a sibling store that creates itself through the canonical directory primitive
• iss-2609091155525689Two accepted decision records describe the directory primitive as it stood before the consolidation, and this repository supersedes rather than amends, so each owes a correction rather than an edit. adr-2609090717039680 (the transcript corpus is a sibling store that creates itself) names ensureRealDir as a helper of internal/core/history and presents its behaviour — walks the chain top-down, os.Mkdir per level rather than MkdirAll, re-verifies every level on every resolve — as a property of that package. Every one of those behaviours still holds, and the symbol does not: it is fsutil.EnsureRealDir, called in a loop, and the package that used to own the sequence now owns only the layout. A reader following the ADR to the code finds nothing at the name it gives. adr-2609091014087993 (a tool never creates directories in user-owned project space) commits a future machine-scoped worktree store to creating itself one level at a time, never through a symlink, exactly as the transcript store does. That sentence is now satisfied by calling the canonical primitive, and it was the reading of it that would have produced a fourth copy: it describes a mechanism where it could name the thing that implements it. What is owed is one correction record covering both — the mechanism is unchanged, the home moved, and a store that wants this behaviour calls internal/fsutil rather than reproducing it. Detector: an ADR that names a package-local symbol should not survive that symbol's removal, which no gate currently checks; the record-lint rule family has no cross-reference from decision prose to Go identifiers.
