 The eval bundle (`evals/skills-bundle/bundle.json`) is a manifest pointing

 truth.

+## Eval evidence
+
+The measurable evidence for these skills is the deterministic, committed,
+executable eval harness in `evals/`:
+
+- **Tier-0 scored replay** — `npm run eval:run -- --scenario evals/scenarios/tier1-directory.json --driver tier0` replays a committed scenario end-to-end against the local fixture and produces a scored JSONL record of the full S0–S11 funnel (no credentials, no network beyond localhost).
+- **Unit smokes** — `npm run eval:test` runs the committed scorer/parser/stages/record/scenario/driver tests.
+- **Scorer + fixture harness** — `evals/runner/score.ts` and `evals/fixture/` are the deterministic scoring and fixture layers the replay exercises.
+
+The Tier-1 baseline E2E (baseline vs with-skills pass rates on a real tenant)
+is structurally blocked: the public repo ships only the Tier-0 canned driver
+(no real-tenant driver), and the c1-side MCP surface on eval environments
+exposes no `c1_connector_authoring_*` tools. Per the carry-forward rule
+established in the merged PRs #10/#11, the baseline blocker is carried
+forward; no pass-rate numbers are reported because none exist.
