 - Issue #84 tracks the DAVE diagnosis showing live health degraded because GDELT, OFAC, and EPA timed out; ACLED returned `403`; ADS-B and Reddit lacked credentials; BLS had an invalid configured key.
 - Code-side fixes in progress on `codex/fix-source-degradation-handling`: GDELT requests are bounded and optional geo enrichment cannot consume the source budget; OFAC uses bounded XML snippet streaming; EPA RadNet uses shorter bounded requests and returns degraded state instead of blocking; BLS retries unauthenticated v1 when `BLS_API_KEY` is rejected and exposes a config warning through source health.
 - Remaining non-code actions after deploy: ACLED account must accept terms/complete profile/API access for `403`; ADS-B needs `ADSB_API_KEY` or `RAPIDAPI_KEY`; Reddit needs `REDDIT_CLIENT_ID` and `REDDIT_CLIENT_SECRET`; BLS key should be removed or replaced if the v1 fallback is acceptable.
+- PR #85 merged as `831cae17295730ee4be0848098cbe9f52cabe716`; PR runs 981-982 and production runs 983-985 passed. The registry image was redeployed to Dockge. Live verification after the new sweep showed GDELT and OFAC no longer degraded; `BLS_API_KEY` was cleared in the Dockge `.env`, and BLS no longer appears in degraded health. Remaining degraded sources are ACLED `403`, ADS-B missing key, EPA RadNet table `404`, and Reddit missing OAuth.
