📝 WalkthroughWalkthroughThe factory now records repository discovery results for index, cache, and tree paths. It reports these metrics through readiness status, public health, and iteration reports. It also tracks consecutive empty sweeps and warns after three empty sweeps. ChangesDiscovery observability
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR is not merge-ready until the duplicate test declaration is fixed so the regression tests can compile and the empty-discovery warning is scoped correctly when Linear and GitHub discovery operate together; otherwise validation is blocked and users may see misleading persistent-empty health warnings.

Superseded by #406. Both PRs implement the same deliverable (silent-empty discovery alarm, 3-consecutive-sweep threshold) and were opened two minutes apart by the same lane. Keeping #406 for two reasons:
The rigor in this PR's body is not wasted: it names the right revert commit (54bfd3f) and the right expectation (the cache-backed repo producing 0 paths with exactly 0 tree reads). That ablation is now required on #406 before it merges. Branch retained until #406 lands. No code judgement against this PR — it is a duplicate, not a defect. |

Summary
Alarm threshold
Three consecutive successful enumerating sweeps with configured repositories and zero candidates. One empty pass can be an ordinary transition; three catches a persistent blind spot within two normal intervals after first observation. The warning is emitted only on the threshold crossing, so a legitimately idle workspace remains visible through counters/status without logging continuously.
Verification
git diff --checkpassesBus errorafter the dependency installer was killed/corrupted; CI must provide executable green evidence before mergeRequired ablation before merge
Run the three new tests on this branch, then revert commit
54bfd3fdcc2f27ea33fddac646f41ba5be4ac9e8locally and run the same tests. Expected ablation failures are missing authority fields/counters/warning, including the cache-backed repo producing 0 paths with exactly 0 tree reads. Do not merge without recording exact pass/fail counts.Summary by cubic
Makes repeated empty discovery sweeps loud: the factory now classifies each configured GitHub repo by which discovery authority served it (issue index, durable cache, or fresh tree), exposes per-authority and empty counts in readiness status and public health, and emits a single warning after three consecutive enumerating sweeps with configured repos and zero candidates. Previously a broken cache or empty index could look like a legitimately idle workspace indefinitely.
