Fixes the missing regression coverage for the replay deep-link routing
reconciliation in SignalOps.

What happened. Commit 36e2c76 fixed a P2 bug where a deep-linked replay
(?replay=&step=) lost its routing rule on first load because the mount
effect ran before the ops snapshot resolved. The reconciliation logic later
grew (range changes, cold-cache transitions, once-per-routing-key guards) but
stayed inline in dashboard.tsx with no direct test — the only guard was a
source-level regex in test-replay-history.mjs. Since signalops's entire
quality story is the pnpm check gate, this fragile state machine was the
highest-value untested logic in the repo.

Change.

• New src/lib/replay-routing.ts: pure resolveReplayRoutingReconcile +
  replayRoutingKey, extracted from the dashboard effect.
• dashboard.tsx effect is now a thin wrapper around the pure decision.
• New scripts/test-replay-routing.mjs (wired into pnpm check as
  test:replay-routing): unknown scenario, out-of-range/negative step
  clamping, once-per-key suppression, range-change re-arm, routingApplied=false
  clear path, empty-steps scenario.
• test-replay-history.mjs structural guard updated to assert the extracted
  decision call.

Verification. pnpm test:replay-routing (new, all assertions pass),
pnpm test:replay-history (updated guard passes), eslint on all touched
files, pnpm typecheck — all clean.

Summary by CodeRabbit

• Bug Fixes
  • Replay routing now applies the appropriate scenario and step when routing changes, while keeping the selected step within the scenario’s available range.
  • Repeated routing decisions are no longer applied when the routing key is unchanged. Missing or unavailable scenarios and steps are handled without applying an invalid routing choice.

Walkthrough

Replay routing reconciliation now uses a shared resolver to select a bounded scenario step and determine whether its routing key needs to be applied. A standalone assertion script covers resolver cases and runs as part of the check sequence.

Changes: Replay routing reconciliation

Layer / File(s)	Summary
Routing decision and resolver assertions src/lib/replay-routing.ts, scripts/test-replay-routing.mjs	The new resolver builds routing keys and returns a scenario, step, and key when reconciliation is needed. Assertions cover missing and empty scenarios, bounded steps, matching keys, and range changes.
Dashboard integration and check registration src/components/dashboard.tsx, scripts/test-replay-history.mjs, package.json	The dashboard applies the resolver’s scenario and step, then records the routing key when setReplayRoutingRule succeeds. The dashboard source assertion and check sequence include the new resolver test.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 4 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

The source-text assertions are tied to one code layout.

The two regexes match the exact text of the decision call and the if (decision && setReplayRoutingRule(...)) guard. Equivalent code with different formatting would fail them. Code that drops the guard in a different layout could still pass. This is a known brittleness of source-text tests. The runtime behavior is covered by scripts/test-replay-routing.mjs, so the risk is low. Keep the assertions as they are, or relax them to the semantic parts: the resolver call and the key write that depends on the setReplayRoutingRule result.
