Why: The E1 live comparison was the only metric that got worse
(unverifiedFacts 7 -> 12): the gate gave one correction round and then
shipped bare numbers. The design (E3) calls for number sourcing with a
mechanically checkable marking escape: numbers labeled as
targets/assumptions are honest planning quantities, not fabricated
facts, so the gate must let them pass - and the model must be told that
marking is the sanctioned way out.
Why: The marking decision is clause-scoped, not a fixed window - a
window wrongly blessed "3,500" because a neighboring clause said
"target 85%" (caught by the existing test). The second round only
fires when the unverified set actually changed, because the
continuation budget is shared across all final gates and a repeat
block on identical tokens starves the downstream gates (also caught by
an existing test).
Evidence: go test ./... green; new anchors TestMarkedAsEstimate,
TestUnverifiedFactsMarksPass, TestFactCheckGateRounds; the live eval
gains an unverifiedUnmarkedFacts field sharing the same marking rule.
Impact: base.deliverables v6 adds the hard number-sourcing rule;
research/explore/general sub-agent profiles v+1 require citations for
key numbers; fact gate: marked-in-clause numbers pass, round 2
escalates to "last interception" with the marking instruction, then
passes through with the check line. Eval report keeps the strict
series and adds the E3-series field.

Why: The live report's model field came back empty because the settings
endpoint nests models under the user scope ({defaults, project, schema, user}),
not at the top level; the before-baseline report had to be annotated by hand.
Evidence: SELF - vet with -tags live passes; the scope shape verified against
GET /api/settings on the qa instance.
Impact: Future live reports carry the served model without manual annotation.
Why: No task-level measurement of real agent behavior existed, so the
failure chain documented in the diagnosis was invisible to CI. The harness
drives a configured backend over its public HTTP surface (upload, message,
poll, HITL auto-resolve), computes per-turn metrics (tool failures, full
regenerations, API-discovery calls, original-material reads, plan usage,
gate checks) and outcome checks (unverified facts vs material text, final
claims vs artifact headings), and writes a JSON + Markdown report.
Evidence: SELF - built behind the live build tag (CI skips); vet passes with
-tags live; drove the qa instance (remote main 1ebd46e) through the four
golden tasks end to end; report referenced on the phase01 task card.
Impact: New eval/live package (tasks.json + runner). Materials stay outside
the repo per eval/README; runs are opt-in via AGENT_EVAL_BASE.
