+# ACTIVITY-WP-0007 - Ops Inventory Probe Runner
+
+## Context
+
+Custodian `CUST-WP-0047` introduced an inventory-first ops-hub slice: a
+non-secret service inventory file, a generated service catalog view, and a
+disabled draft ActivityDefinition for repeatable service inventory probes.
+State Hub message `d543c39c-1f04-4f1e-a1e4-0d5b40503525` handed the
+activity-core portion to this repo.
+
+The request fits activity-core only if it stays narrow. activity-core should
+provide scheduled policy, bounded context resolution, deterministic lightweight
+HTTP/HTTPS checks, and non-secret evidence emission. It must not become an ops
+executor, secret handler, Inter-Hub operator, k8s/ssh/tunnel runner, or service
+inventory authority.
+
+Existing activity-core capabilities that make this feasible:
+- cron/manual ActivityDefinitions and Temporal orchestration
+- external definition scanning via `ACTIVITY_DEFINITION_DIRS`
+- static context sources and pluggable context resolvers
+- State Hub context resolver and State Hub progress report sink pattern
+- working-memory sink, NATS/EventEnvelope routing, and event type registry
+
+Known gaps this workplan closes:
+- no `ops-inventory` resolver for `service-inventory.yml`
+- no deterministic endpoint/access-path probe result model
+- no non-LLM evidence sink for ops probe summaries
+- no ops evidence event definitions owned by activity-core
+- no Railiance projection for the Custodian probe definition or inventory input
+
+## Add Ops Inventory Context Resolver
+
+```task
+id: ACTIVITY-WP-0007-T01
+status: todo
+priority: high
+```
+
+Add a registered context resolver:
+
+- source type: `ops-inventory`
+- query: `probe_services`
+- params: `inventory_path`, `timeout_seconds`, `include_kinds`,
+  `allow_network`, `required`
+
+The resolver reads and validates a non-secret service inventory YAML file,
+initially `/home/worsch/the-custodian/ops/service-inventory.yml` when present.
+It produces compact structured output:
+
+```json
+{
+  "services": [],
+  "endpoints": [],
+  "summary": {"ok": 0, "degraded": 0, "down": 0, "skipped": 0},
+  "generated_at": "..."
+}
+```
+
+First implementation scope:
+- HTTP/HTTPS endpoint probes only
+- expected status and expected signal checks only
+- non-HTTP, k8s, ssh, tunnel, and authenticated access paths return
+  `skipped` / `unsupported`, not failed
+- missing optional inventory returns `{}` or a skipped summary unless the
+  context source is required
+- no response bodies, cookies, authorization headers, tokens, or command output
+  are stored
+
+Done when fixture-based resolver tests cover `ok`, expected-status mismatch,
+expected-signal mismatch, network/down, unsupported, and optional/required
+inventory failure behavior.
+
+## Add Ops Evidence Sink
+
+```task
+id: ACTIVITY-WP-0007-T02
+status: todo
+priority: high
+```
+
+Add a deterministic non-LLM evidence sink for compact probe results.
+
+Initial sink behavior:
+- sink type: `state-hub-progress`
+- State Hub event type: `ops_inventory_probe`
+- idempotency key: `activity_core_run_id + service_id + endpoint_id/access_path_id + event_type`
+- detail contains compact non-secret results only
+- one summary progress event per run is acceptable for the first version
+
+Prepare the contract for later Inter-Hub submission without making it mandatory:
+- event names: `ops-service-observed`, `ops-endpoint-verified`,
+  `ops-access-path-checked`, `ops-backup-verified`, `ops-inventory-drift`
+- Inter-Hub mode requires `INTER_HUB_URL`, `OPS_HUB_KEY` from Secret, and
+  widget/capability mapping config
+- missing Inter-Hub config skips cleanly with an explicit sink result
+
+Done when sink idempotency, State Hub fallback posting, missing Inter-Hub
+config, and no-secret-leak behavior are covered by tests.
+
+## Register Ops Evidence Event Definitions
+
+```task
+id: ACTIVITY-WP-0007-T03
+status: todo
+priority: medium
+```
+
+Add activity-core-owned event type definitions for ops evidence so producers
+and future widgets have a stable contract:
+
+- `ops-service-observed`
+- `ops-endpoint-verified`
+- `ops-access-path-checked`
+- `ops-backup-verified`
+- `ops-inventory-drift`
+
+Each definition must document:
+- publisher intent
+- non-secret attribute schema
+- idempotency fields
+- examples for success, degraded, down, skipped, and drift where applicable
+- explicit forbidden payload material: secrets, auth headers, cookies, raw
+  response bodies, command output, and token-like values
+
+Done when event registry tests or parser coverage prove the definitions are
+valid and reviewable.
+
+## Wire Custodian Definition Safely
+
+```task
+id: ACTIVITY-WP-0007-T04
+status: todo
+priority: medium
+```
+
+Accept the Custodian-owned disabled draft definition:
+
+`/home/worsch/the-custodian/activity-definitions/ops-service-inventory-probes.md`
+
+Requirements:
+- support sync/parse with
+  `ACTIVITY_DEFINITION_DIRS=/home/worsch/the-custodian`
+- keep the definition disabled until resolver, sink, and deployment wiring pass
+- add parser/sync tests for external definition directories
+- ensure manual trigger of a disabled definition in test/dev can produce fixture
+  evidence without enabling the production schedule
+
+Done when activity-core can scan the Custodian definition path without enabling
+it prematurely.
+
+## Wire Railiance Runtime Inputs
+
+```task
+id: ACTIVITY-WP-0007-T05
+status: todo
+priority: medium
+```
+
+Wire the production deployment only after the local resolver/sink tests pass.
+
+Scope:
+- project the new disabled Custodian definition into
+  `actcore-external-activity-definitions`
+- decide how the worker sees the inventory input:
+  - generated ConfigMap from `service-inventory.yml`
+  - mounted repo snapshot
+  - State Hub endpoint if Custodian later exposes the inventory
+- add config placeholders for `OPS_INVENTORY_PATH`, `INTER_HUB_URL`, and widget
+  mapping
+- keep `OPS_HUB_KEY` in Secret only
+
+Done when the Railiance worker can see the disabled definition and inventory
+input without leaking secrets or activating the schedule early.
+
+## Close Safety And Handoff Gates
+
+```task
+id: ACTIVITY-WP-0007-T06
+status: wait
+priority: medium
+```
+
+Complete the operational handoff only after the safety gates are satisfied.
+
+Acceptance criteria:
+- a disabled manual trigger runs the ops inventory probe against fixture or
+  non-production inventory data and produces compact non-secret evidence
+- State Hub progress receives one `ops_inventory_probe` summary per run
+- Inter-Hub submission is either implemented behind config/secret gates or
+  explicitly deferred with a clean sink result
+- the activity-core worker can sync the Custodian definition without enabling it
+  prematurely
+- no k8s, ssh, tunnel, or authenticated command execution is required for the
+  first version
+- `CUST-WP-0047-T07` has enough evidence to move from `progress` toward done
+
+This task waits on the implementation tasks above and, for final Inter-Hub
+activation, the operator-gated ops-hub widget/API-key path in `CUST-WP-0047`.
+
+## Review Verdict
+
+activity-core should provide this as a bounded probe-and-evidence capability.
+It should not provide a general operational execution engine. The first useful
+slice is safe and valuable if it remains HTTP/HTTPS-only, non-secret, disabled
+until explicitly wired, and idempotent in its evidence output.
