How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

163-166: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick winUpdate the assertion message to match the renamed test.
The test now covers dedupe namespace resolution, but the failure message still says "fingerprint query error". Align the message with the resolver under test.
💚 Proposed message fix
assert!( error.to_string().contains("no such table: meta"), - "expected the fingerprint query error, got: {error:#}" + "expected the dedupe namespace query error, got: {error:#}" );🤖 Prompt for AI Agents

60-85: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueShare the metadata key names instead of repeating string literals.
This migration hardcodes
'modem_fingerprint'and'modem_dedupe_namespace'.src/persistence/mod.rsdefines the same names as constants (MODEM_FINGERPRINT_META_KEY,MODEM_DEDUPE_NAMESPACE_META_KEY). A rename in one place will not update the other, and the migration would then silently stop matching. The same literals also appear ininbound_dedupe_namespace_onat lines 121-140.Define the key names once in the storage layer and bind them as parameters, or re-export the existing constants for use here.

149-164: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExtract the duplicated resolve-and-publish block.
The same six-line sequence (call
resolve_monitor_path, publish on success, log and clear targets on error) appears at lines 149-164 and again at lines 180-194. Extract one private helper so both call sites share a single failure policy.async fn resolve_and_publish(&self) -> Option<String> { match resolve_monitor_path( &self.settings.configured_modem_path, &self.modem_service, &self.store, ) .await { Ok(resolved) => publish_resolved_path(&self.modem_service, resolved), Err(error) => { error!("modem resolution failed: {}", error); self.modem_service.set_modem_targets(ModemTargets::default()); None } } }Also applies to: 180-194

454-462: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winUpdate the doc comment to describe the target split.
The comment still describes a single resolved path. The function now returns
ModemTargetswith two independent meanings, and the safety-relevant rule is not stated: a modem selected only by an observed runtime fingerprint, or a sole available modem at a different path, becomes a runtime target but never an action target.State the return contract explicitly, including when
verified,separate,runtime_only,action_only, and the empty default are produced. Readers ofrun_actiondepend on this rule.🤖 Prompt for AI Agents

258-328: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExtract the repeated fingerprint-comparison block.
Lines 264-282 and lines 291-315 implement the same three-way decision on
store.modem_fingerprint(): enrol when absent, do nothing when equal, revoke and persist a mismatch when different. Only the extra namespace pinning at lines 308-313 differs.Extract one helper that takes the path to enrol or quarantine and returns whether a mismatch was recorded. The caller then performs the namespace pinning. A single implementation prevents a future correctness fix from landing in only one of the two branches.

- Around line 1474-1481: Replace the fixed 50 ms sleep in the test with a
bounded poll using the existing timeout/polling pattern from nearby tests,
waiting until runtime_modem_fingerprint() returns the expected target
fingerprint. Keep the final fingerprint and verified_path assertions, and fail
when the timeout expires.
