main fails typecheck since #24982: it made homePath required on transcript candidates, and the Pi session discovery from #27515 still builds candidates without it (AgentSessionScanner.ts:1203, TS2741). Every CI run on main since then fails Build and Typecheck.

Pi candidates now pass homePath: sessionsDir. For Pi the resolved home path is the sessions directory (resolvePiSessionsDir), and homePath is only read for Codex thread names, so Pi behavior is unchanged.

Checked: vp run typecheck passes for the whole repo, and AgentSessionScanner.test.ts passes (54 tests).

Approvability

Verdict: Approved at 7d19258

Macroscope's review found this PR approvable — Pi transcript candidates now carry their existing sessions directory as home-path metadata. This narrowly scoped change leaves discovery scope and product defaults unchanged.
