The old harness mocked submit_order and classified success by whether
the strategy POSTed an order. The redesigned ethflow-watcher strategy
GETs /api/v1/orders/{uid} instead — so every fixture previously
classified as RejectedUnexpected and the binary exited 1.
Now programs a 200 catch-all for cow_api_request, classifies success
by whether observed:{uid} was written to local store, and renames the
Submitted classification to Observed throughout.
Closes #45

- classify_ok now checks `observed:{uid}` (exact fixture UID) instead of
any `observed:*` prefix — prevents a compute_uid mismatch from producing
a false Observed classification
- report.rs intro: corrected "programs a 200 for GET /orders/{uid}" to
reflect the actual catch-all mock setup
- RejectedExpected variant doc: broadened from "404 only" to "any documented
skip path" so future skip paths are not misleadingly excluded

Review follow-ups on top of the rebase onto develop:
- classify_ok now demands the full observe contract, not just the
store marker: zero submit_order calls and exactly one
GET /api/v1/orders/{uid} against the fixture's UID. A regression
that writes the marker after a different call shape (or that also
submits) is classified RejectedUnexpected instead of Observed, so
the backtest stays an independent check on the module tests.
- Regenerated docs/operations/backtest-reports/backtest-7d-2026-06-22.md
from the committed fixtures: 240/240 (100.0%) Observed, replacing the
stale submit-era report (issue #45's "stale and unreproducible" item).
Verified: cargo run -p shepherd-backtest -- --fixtures
tools/backtest-collect/fixtures-2026-06-22.json exits 0 with 240/240.

Summary
ethflow-watcherstrategy was redesigned from submit-based to observe+verify (GETs/api/v1/orders/{uid}, writesobserved:{uid}to local store). The backtest harness was never updated, so every fixture classified asRejectedUnexpectedand the binary exited 1.submit_order+app_datamocks; added a catch-all 200 response forcow_api_requestSubmitted→Observedthroughout (replay.rs,report.rs,main.rs)classify_oknow checks local store forobserved:*key instead ofsubmit_ordercall countsubmitted_bodyfield fromReplayOutcomeCloses #45

cargo test -p ethflow-watcher— 11/11 pass (covers the full observe+verify strategy)cargo check -p shepherd-backtest— zero warningsbacktest_collect.py— 5/5 Observed, 100%, exit 0Observed + RejectedExpected
