Struct CapabilityHooks 

pub struct CapabilityHooks {
    pub registered_count: usize,
    pub webhook_events: Vec<String>,
    pub hook_events_count: usize,
    pub auto_export_spawn_failed_total: u64,
}

Hook-pipeline block (capabilities schema v2). Pre-v0.7 reports webhook subscriptions as the closest analogue. The full hook pipeline lands in v0.7 Bucket 0 (arch-enhancement-spec §2).

Fields

registered_count: usize

Number of registered hook subscribers (proxy: webhook subscriptions).

webhook_events: Vec<String>

v0.6.3.1 P5 (G9): canonical list of webhook event types the daemon emits. Integrators pin the subscribe(event_types: …) filter against these strings. Always populated so downstream callers do not have to handle a missing field.

hook_events_count: usize

v0.7.0 L1-7: total number of distinct HookEvent variants the pipeline supports. Populated from the compile-time constant HOOK_EVENTS_COUNT so operators and integrations can verify they are running against the expected pipeline version without enumerating the enum.

History: G2 shipped 20; G10 added the 21st; Task 6/8 added the 22nd + 23rd; L1-7 adds the 24th + 25th → total 25.

auto_export_spawn_failed_total: u64

v0.7-polish SEC-15 / COR-11 (issue #780): mirror of the process-wide crate::metrics::auto_export_spawn_failed_total counter. Non-zero means at least one post_reflect.auto_export detached worker panicked or returned Err since process start — the reflection is committed in the DB but its on-disk markdown/json artefact did NOT land. Operators alert on a non-zero value without scraping /metrics directly.

skip_serializing_if = is_zero_u64 keeps healthy daemons’ capabilities responses byte-identical to pre-#780 — only daemons that have actually hit the failure path see the field on the wire. The MCP/HTTP capabilities builder overlays the live value at response time.
