[MainSequenceDev]

Why

Repositories folder. Claude Desktop keeps its own copy of the repositories folder. Codex and the mainsequence CLI share mainsequence_path in the CLI's config.json. Changing the folder in one tool doesn't reach the others. To unify them, Claude needs to save just the folder into the shared file and to know whether the file already names one.

Agent storage lock. CI failed once on this branch in a process killed after send leaves an uncertain record, with STORE_ERROR after the store's 3-second lock wait. The same commit passed in the other run. The cause is in the store:

• The lock file was created empty and its owner written afterwards.
• wait takes the lock every 250 ms while a send runs.
• A process killed between those two steps left an empty lock, which is never reclaimed by design.
• Every later call then failed with "Saved agent requests could not be read safely" until someone deleted the file by hand.

What changes

• writeWorkspacePreferences({ backend?, baseDir?, commandCenterUrl? }) saves only the fields it is given and keeps every other setting. A call with none is refused. The Codex plugin passes all three, so its behaviour is unchanged.
• readWorkspacePreferences also returns baseDirSaved: true when the folder comes from the shared configuration rather than the <home>/mainsequence default.
• The agent store's lock is created with its owner already in it. The owner record is written to a private file, which is then linked into place; the link fails while another lock exists.
  • A process killed at any moment leaves either no lock, or a lock naming a dead owner, which the next call reclaims.
  • An owner killed between linking and cleaning up leaves its private file behind; that file is removed during reclamation.
  • An empty lock left by an older version is removed once it is ten seconds old, under a durable claim. A new empty lock is still waited for, because its owner may still be writing.

Verification

npm run release:check passes: 189 tests, plus the docs and package checks. New tests:

• { baseDir } is saved alone, baseDirSaved is reported both ways, and an empty call is refused.
• A dead owner's lock that still has its second name is reclaimed.
• A fresh empty lock is waited for, then refused; a stale one is removed.

The killed-process test passed 30 times in a row.
