sentinel-2026-05-07T08:00:00Z C002mediumThe enrichment agent explicitly recognized a boundary condition (feed system returning no results) and explicitly recognized budget exhaustion (tool budget exhausted). It then chose to proceed with ou…
sentinel-2026-05-09T08:00:00Z C003mediumThe briefing_enrichment agent recognized explicitly that its feed searches returned zero results — attributing this to the database "not yet containing" the intelligence items. Despite this acknowledg…
sentinel-2026-05-10T08:00:00Z C001highThe briefing_enrichment agent explicitly recognized that its feed search capability was unavailable for the target date — 'all five targeted feeds_search queries returned no matches or database date-p…
sentinel-2026-05-16T08:00:00Z C001highThe enrichment agent explicitly diagnosed a total feed failure ('all feed searches encountered database schema constraints and returned no matches') and then proceeded to produce a five-section enrich…
sentinel-2026-05-18T08:00:00Z C005mediumThe deadline_awareness agent started at 06:00:30Z (id 407) and received an HTTP 529 overloaded error at 06:00:57Z (id 408). No subsequent retry or escalation is visible in the timeline — the agent's r…
sentinel-2026-05-19T08:00:00Z C002mediumThe briefing_enrichment agent reported that its five external feed searches returned no matches beyond the briefing source material itself, then reframed this null result as validation — "indicating t…
sentinel-2026-05-20T08:00:00Z C003mediumThe briefing_enrichment agent encountered null external feed results, correctly identified this in the degradation header, and then proceeded to produce a full five-item enrichment artifact repackagin…
sentinel-2026-05-22T08:00:00Z C002mediumThe deadline_awareness agent started at 06:00:30Z (id 461) and received an HTTP 529 overloaded error at 06:00:55Z (id 462). No subsequent retry or escalation is visible in the timeline — the agent's r…
sentinel-2026-05-22T22:00:00Z C003mediumThree agents (briefing-morning, deadline_awareness, briefing_enrichment) failed the 06:00-06:25Z window due to Anthropic HTTP 529 overload. Each exhausted its 3-attempt retry budget (~12 seconds total…
sentinel-2026-05-23T08:00:00Z C001mediumThe briefing_enrichment agent recognized a boundary condition — all four external feed searches returned zero results — and explicitly noted it in the Method section (and in the DEGRADED header logged…
sentinel-2026-05-24T08:00:00Z C001mediumThe cve_triage agent reached the maximum iteration budget (5) while a tool call was still in flight. The runtime logged this as a blocker event and set disposition=degraded. The resulting staging arti…
sentinel-2026-05-24T08:00:00Z C003mediumThe briefing_enrichment agent's own DEGRADED header declares the exact failure condition — missing bracketed source citations — at the top of the artifact. Having self-flagged the output as non-author…
sentinel-2026-05-25T08:00:00Z C001highThe briefing_enrichment agent self-flagged that its output was deficient — the required bracketed source citations were absent — and then produced the artifact anyway with only a header warning rather…
sentinel-2026-05-26T08:00:00Z C004mediumThe briefing_enrichment agent executed five external searches and returned zero additional signal for four of the five enrichment targets. Rather than surfacing this null-result condition to the opera…
sentinel-2026-05-27T08:00:00Z C004mediumThe briefing_enrichment agent self-discloses its tool-call budget constraint and explicitly notes that 3 of 5 enrichment targets returned no additional signal ('did not return additional contextual re…
sentinel-2026-05-28T08:00:00Z C002mediumThe briefing_enrichment agent explicitly self-flagged its output as DEGRADED with the precise reason 'no bracketed source citations,' added a disclaimer 'Not authoritative; operator review required,' …
sentinel-2026-05-29T08:00:00Z C002mediumThe briefing_enrichment agent self-flagged its own output as DEGRADED with the explicit reason 'enrichment artifact has no bracketed source citations' (timeline id=567, category=blocker). Despite this…
sentinel-2026-05-30T08:00:00Z C003mediumThe briefing_enrichment agent explicitly documented that all four primary feed searches returned zero results, attributing this to future-dated CVE content. Despite this acknowledged null-signal condi…
