AI Discovery ran a separate model-backed service scanner beside Patrol
and the Assistant: its own store, scheduler, model route, API, tool and
drawer UI. No telemetry counter ever measured its use (the telemetry
discovery_enabled flag OR'd it with network subnet discovery), the
maintainer judged it a flop, and the context it produced is already
available to the models through pulse_query, pulse_read and the
unified-resource context sections.
This deletes internal/servicediscovery, internal/ai/infradiscovery, the
pulse_discovery tool, the /api/discovery routes, the mock Discovery
fixtures, the Discovery tabs in the resource, guest, node and Docker host
drawers, the identified-service cards, readiness badges, provenance
markers, suggested web-interface URLs, the Workloads AI Context column,
the chat "Discovery is off" hint and the AI Service Context settings page.
The old settings route redirects to Assistant settings. The model-bound
sanitizer allow-list existed only to pass Discovery context through, so it
goes too, along with the CopyableCodeRow primitive that only the
Discovery tab used.
Network subnet discovery (/api/discover, the Infrastructure discovery
settings) and the discoveryTarget agent coordinates are separate features
and stay. Stored discovery_enabled, discovery_interval_hours and
discovery_model AI settings are ignored on load; the settings API decoder
is lenient, so older frontends saving those fields still succeed.
Test-only wave, contract-neutral. New *_branchcov0719pm_test.go files cover
previously-uncovered pure value-in/value-out helpers, each verified to move
its target functions from 0% to full coverage:
- internal/agentcontext: formatKubernetesServicePorts (empty/single/cap/overflow
arms) and addMetricFact (nil-metric, percent/value/ratio arms) now 100%.
- pkg/reporting: reportLogoTypeFromPath 0->100, reportLogoTypeFromData 28.6->100,
scaledLogoSize 70->90 (extension and aspect branches).
- internal/cloudcp/email: RenderMagicLinkEmail 0->80 (render success path; the
compile-time template-error arm is unreachable and left uncovered).
- internal/recovery: recoveryDetailString (nil map, missing key, non-string,
string arms) and recoveryPointObservedAt 40->100.
- internal/ai/tools: ErrStrictResolution/ErrRoutingMismatch ToToolResponse 100.
- internal/ai/providers: every NormalizeCollections receiver 0->100.
