fix(memories): record the resolved path, not the raw pointer (FT-MR11) - #1

What was wrong

generateIndex resolved each MEMORY.md reference correctly — trying the store directory, then its parent — and then discarded the result, storing ref.path verbatim (index-gen.ts entry builders).

The canonical store writes pointers as memory/foo.md, where memory/ is a namespace label for the store, not a subdirectory of it. So the CLI's rewritePathsAbsolute re-applied the prefix against the store root alone and emitted a doubled …/memory/memory/foo.md.

Why it mattered

On the canonical store this left 420 of 492 published entries (85%) pointing at files that do not exist.

The UserPromptSubmit hook reads that published index on every prompt in every session. When it hands a session a path that isn't there, the session either gets nothing or paraphrases from the one-line summary — which is exactly what the store's own rule forbids ("open the file pointer before acting, do not paraphrase from the summary"). This was silently degrading memory recall everywhere.

The fix

Entries now record the location that actually resolved, relative to the store root with POSIX separators. Both of the store's drifted layouts (274 flat files + 70 nested) resolve, and no memory file has to move — the store is not version-controlled, so not touching it was the low-risk path.

Store-relative rather than absolute keeps the on-disk index portable, which is the contract rewritePathsAbsolute depends on.

Acceptance test

GLOBAL (the hook reads this):  492/492 resolve   BROKEN: 0
STORE (on-disk index)       :  492/492 resolve   BROKEN: 0

Was 72/492. The 59 genuinely-nested entries still resolve correctly.

Why the tests missed it

The original fixture puts MEMORY.md above its memory/ directory, so every ref matched on the first base and the parent-base fallback was never exercised. That is how this reached production.

fixtures/flat-store/ pins the real shape — MEMORY.md inside the store, one flat topic, one genuinely-nested topic — and asserts every entry resolves once joined onto the store root, mirroring the live acceptance check.

Also in this PR

DEFAULT_STORE was an absolute literal containing a username, so the shipped default resolved on exactly one computer and leaked that username into a public package. Now derived from homedir(), matching defaultDest() directly below it. Remaining username literals in repo instructions and test data are gone too.

identity-scan reads RESULT CLEAN; it previously reported HIT 12 on main.

Verification

• npm run verify — 383 tests across all four packages, 0 fail, exit 0
• identity-scan.py — RESULT CLEAN
• loadout-os refresh — exit 0, no andon halt, live index repaired

Not in scope

Publishing to npm is the Director's call, so the version is unbumped and the entry sits under [Unreleased]. Until a release ships, the global loadout-os binary (v1.0.2) still carries the bug — the live index was repaired by running this branch's build directly.
