projectLabel() basenames the primary checkout root to build the Hindsight
`project:` tag, and it preserved case. Hindsight matches tags literally,
so a checkout at ~/code/General retained and recalled under
`project:General` while every other client of the same bank used
`project:general`. One repository then owns two scopes that never meet:
recall filters on the session's own tag, so neither side sees the other's
facts, and consolidation treats them as unrelated projects. A live bank
measured 581 facts stranded under a case variant on 2026-08-09.
Fold the case at the source, after the primary-root resolution added for
issue #2232, so the worktree axis and the casing axis collapse together.
Per-project bank ids lowercase for the same reason.
- hindsight/bank.ts: lowercase the resolved basename, and document why.
- test/hindsight-bank.test.ts: cover the fold on plain paths, on a
mixed-case checkout root, and on a linked worktree of one. The non-repo
fallback assertion now folds its own mkdtemp suffix.
- docs/memory.md: state how the project label is derived.
- CHANGELOG: Fixed entry under Unreleased.
