 *
 *   1. `--session-id <sid>`             — explicit wins
 *   2. `PEAKS_SESSION_ID` env var       — scripted / sub-process callers
 *   3. `getCurrentSessionId(projectRoot)` — this caller's OWN binding
 *      (`callers/<callerId>.json`) falling back to the project-global
 *      `.peaks/_runtime/session.json`, the same resolver `peaks session
 *      info --active` and `peaks session checkpoint` use
 *   4. `unknown-sid`                    — nothing is bound
 *
 * Tier 3 was MISSING until 2026-09-15 (S6), and its absence is the whole
 * defect: `workflow init` resolved on tiers 1–2 only, so with no flag and no
 * env var it wrote the graph into `.peaks/_runtime/unknown-sid/graphs/`
 * regardless of what the binding file said. `peaks workflow node prepare`
 * then ran under the CORRECT session dir and reported `PEAKS_GRAPH_NOT_FOUND`
 * — the graph it was asking for had been written one bucket over. The bucket
 * accumulated artifacts from at least 4 distinct caller ids between 2026-09-01
 * and 2026-09-15, i.e. it had never worked for anyone.
 *
 * The same prior-art sweep (`.peaks/memory/archived/2026-06-26-unknown-sid-root-cause.md`)
 * converted six inline `?? 'unknown-sid'` sites to this 4-tier chain;
 * `workflow-lifecycle-commands.ts` was missed. This is that site.
 *
 * The project root passed to tier 3 goes through the same `findProjectRoot`
 * walk `session info` uses, so a command run from a SUBDIRECTORY of the
 * project resolves the project's binding instead of `cwd`'s (which has none).
