## Profile system (`--profile`, v4.1.0)
Three built-in model profiles plus operator-defined `<custom>.yaml`. Each profile pins `phase_models` for the six pipeline phases (`brief`, `research`, `plan`, `execute`, `review`, `continue`). Profile is recorded in plan.md frontmatter as `profile: <name>` and emitted to `${CLAUDE_PLUGIN_DATA}/trek*-stats.jsonl` for cost-attribution.

| Profile | Brief | Research | Plan | Execute | Review | Continue | Use case |
|---------|-------|----------|------|---------|--------|----------|----------|
| `economy` | sonnet | sonnet | sonnet | sonnet | sonnet | sonnet | ⚠ **Experimental** (uncalibrated Jaccard floor) — lowest cost; high-confidence small-scope tasks (operator-opt-in via `--profile economy`) |
| `balanced` | sonnet | sonnet | opus | sonnet | opus | sonnet | Mixed — opus where reasoning depth pays off (operator-opt-in via `--profile balanced`) |
| `premium` (default) | opus | opus | opus | opus | opus | opus | Maximum quality — Opus on every phase. Default since 2026-05-13 operator request; also the hardcoded resolver default returned by `resolveProfile()` in `lib/profiles/resolver.mjs` |
| `fable` | fable | fable | fable | fable | fable | fable | Max quality — Fable 5 (Mythos-class, above Opus) on every phase (operator-opt-in via `--profile fable`); reasoning effort inherits from the session — see `docs/profiles.md` §Model & effort axes |

### Custom profiles
Create `voyage-profiles/<custom>.yaml` in the repo root (or `~/.claude/voyage-profiles/<custom>.yaml`) to define a **new** tier — the name must not be a built-in. The validator (`lib/validators/profile-validator.mjs`) enforces: every `phase_models[].phase` must be a known phase enum; every `phase_models[].model` must match `^(opus|sonnet)(\b|-).*` or one of the canonical short names. `findProfilePath` (`lib/profiles/resolver.mjs`) resolves **built-in first** (`lib/profiles/<name>.yaml` for `economy`/`balanced`/`premium`), then repo-root `voyage-profiles/`, then `~/.claude/voyage-profiles/`. A custom file named after a built-in therefore **cannot** shadow it (custom profiles must use new names); for the same custom name, repo-root takes precedence over home.
Create `voyage-profiles/<custom>.yaml` in the repo root (or `~/.claude/voyage-profiles/<custom>.yaml`) to define a **new** tier — the name must not be a built-in. The validator (`lib/validators/profile-validator.mjs`) enforces: every `phase_models[].phase` must be a known phase enum; every `phase_models[].model` must exactly match an entry in `BASE_ALLOWED_MODELS` (`['sonnet', 'opus', 'fable']`; `haiku` only with `VOYAGE_ALLOW_HAIKU=1`). `findProfilePath` (`lib/profiles/resolver.mjs`) resolves **built-in first** (`lib/profiles/<name>.yaml` for `economy`/`balanced`/`premium`/`fable`), then repo-root `voyage-profiles/`, then `~/.claude/voyage-profiles/`.

Drift between plan-frontmatter `profile:` and step-manifest `profile_used:` emits a `MANIFEST_PROFILE_DRIFT` warning from `plan-validator --strict` (Step 20). Plan remains valid; the warning surfaces accidental tier-mismatch.
