+### Scheduled agent execution (WP-0006, ADR-005)
+
+Beyond the metrics-only definitions above, agents themselves run on a cadence
+against a **preselected repo roster**. The roster combines three sources:
+
+| Source | Purpose |
+|--------|---------|
+| State Hub `GET /repos/` | Canonical slug list + `host_paths` |
+| Repo opt-in: `.kaizen/schedule.yml` exists with `version` set | Per-repo enablement |
+| Optional hub flag `kaizen_schedule_enabled: true` (future) | Operator override |
+
+A repo is **schedule-eligible** when it is registered with reachable
+`host_paths` **and** carries a valid `.kaizen/schedule.yml`. The activity-core
+resolver `discover_kaizen_scheduled_repos` intersects these and emits
+`context.scheduled_runs` (one entry per `(repo, agent)`); definitions `for_each`
+over that output.
+
+| Definition | Trigger | Agent | Prepare command |
+|------------|---------|-------|-----------------|
+| [weekly-coach-orientation](integrations/activity-definitions/weekly-coach-orientation.md) | Cron Mon 09:00 | `coach` | `schedule prepare coach` |
+| [weekly-optimization-review](integrations/activity-definitions/weekly-optimization-review.md) | Cron Mon 10:00 | `optimization` | `schedule prepare optimization` |
+
+**Listing schedule-eligible repos** (operator, no activity-core code):
+
+```bash
+# In each candidate repo on a host listed in state-hub host_paths:
+kaizen-agentic schedule validate && kaizen-agentic schedule list
+```
+
+**Design docs (no state-hub / activity-core code in this repo):**
+
+- [schedule-schema.md](integrations/schedule-schema.md) — `.kaizen/schedule.yml`
+- [state-hub-roster-fields.md](integrations/state-hub-roster-fields.md) — hub fields/filters
+- [discover-kaizen-scheduled-repos.md](integrations/discover-kaizen-scheduled-repos.md) — resolver spec

+**Boundary:** kaizen-agentic declares and prepares; activity-core schedules;
+state-hub owns the roster.

+
+- **`kaizen-agentic` on PATH** — `pip install kaizen-agentic` (or `pipx install

+    --extra-index-url https://gitea.coulomb.social/api/packages/coulomb/pypi/simple/
+  ```
+- **Repo checkout reachable** at the `host_paths[<host>]` registered in State
+  Hub, with a valid `.kaizen/schedule.yml` (`kaizen-agentic schedule validate`).
+- **No State Hub required for `prepare`** — `schedule prepare` reads local
+  `.kaizen/` state only. The hub is needed by the *resolver* (activity-core),
+  not by the prepared session.
+
+**Enabling a definition** (activity-core operator): keep the kaizen definitions
+at `enabled: false` until a manual smoke test passes (see
+[INTEGRATION_PATTERNS.md Pattern 2](INTEGRATION_PATTERNS.md) and the
+[activity-core handoff checklist](integrations/activity-core-handoff-wp0006.md)),
+then flip one definition to `enabled: true` in staging before fleet-wide enable.

+
+# ADR-005 — Scheduled Agent Execution Convention
+
+## Status
+
+Accepted
+
+## Context
+
+Kaizen agents are markdown instruction sets invoked in coding-agent sessions.
+ADR-004 added project-scoped metrics; WP-0004 committed three metrics-focused
+`ActivityDefinition` drafts (`enabled: false`). What is still missing is a way to
+run **agents themselves** — not just the metrics optimizer — on a **regular
+cadence** against a **preselected set of repos**, without kaizen-agentic owning
+Temporal workers, cron, or an LLM runtime.
+
+The ecosystem already separates concerns:
+
+- **activity-core** owns scheduling (cron/event → task creation).
+- **state-hub** owns the canonical repo roster and `host_paths`.
+- **kaizen-agentic** owns the agents, project memory, and metrics.
+
+A scheduled agent run therefore needs a contract that crosses these repos
+without merging them.
+
+## Decision
+
+Introduce a **repo-local schedule manifest** and a **prepare** step. The
+end-to-end flow:
+
+```
+activity-core cron
+  → context resolver (roster ∩ repos with schedule.yml)
+  → task per (repo, agent)
+  → coding-agent session runs `kaizen-agentic schedule prepare <agent>`
+  → session executes the agent instructions in that repo
+```
+
+kaizen-agentic's responsibilities are exactly two: **declare** the schedule
+(`.kaizen/schedule.yml`) and **prepare** an orientation bundle for a run. It
+does **not** fire cron, create tasks, or invoke Claude.
+
+### 1. Schedule manifest — `.kaizen/schedule.yml`
+
+A repo opts into fleet scheduling by committing this file:
+
+```yaml
+version: "1"
+timezone: Europe/Berlin
+agents:
+  coach:
+    cadence: weekly
+    cron: "0 9 * * 1"      # optional override; default from ActivityDefinition
+    enabled: true
+  optimization:
+    cadence: weekly
+    cron: "0 10 * * 1"
+    enabled: true
+  tdd-workflow:
+    cadence: monthly
+    enabled: false
+```
+
+**Schema:**
+
+| Key | Required | Type | Notes |
+|-----|----------|------|-------|
+| `version` | yes | string | Must be `"1"` |
+| `timezone` | no | string | IANA tz; default supplied by ActivityDefinition |
+| `agents` | yes | mapping | `agent-name → settings` |
+| `agents.<name>.cadence` | yes | enum | `daily` \| `weekly` \| `monthly` |
+| `agents.<name>.cron` | no | string | 5-field cron; overrides cadence default |
+| `agents.<name>.enabled` | no | bool | Default `true` |
+
+**Validation rules** (`kaizen-agentic schedule validate`):
+
+- `version` must equal `"1"`.
+- Every agent key must be an installed or packaged agent name.
+- `cadence` must be one of the allowed values.
+- Duplicate agent entries are rejected.
+
+### 2. Roster (preselected repos)
+
+A repo is **schedule-eligible** when **all** of:
+
+1. It is a registered repo in state-hub (`GET /repos/`) with reachable
+   `host_paths`.
+2. It contains a valid `.kaizen/schedule.yml`.
+3. (Optional, future) it carries a `kaizen_schedule_enabled: true` hub flag.
+
+The resolver `discover_kaizen_scheduled_repos` (specified in
+`docs/integrations/discover-kaizen-scheduled-repos.md`, implemented in
+activity-core) intersects these sources and emits `context.scheduled_runs`.
+
+### 3. Prepare bundle — `schedule prepare <agent>`
+
+Assembles, from **local `.kaizen/` state only** (offline-safe):
+
+- The agent prompt (`agents/agent-<name>.md`, installed or packaged).
+- Project memory (`.kaizen/agents/<name>/memory.md`) when present.
+- Metrics summary (`.kaizen/metrics/<name>/summary.json`) when present.
+- Repo pointers (`SCOPE.md`, `TODO.md`) when present.
+- Suggested session-close commands (`metrics record`, memory update).
+
+Output is `markdown` (default) or `json` (`--format json`) so activity-core can
+embed it in a task `description` or a runner can parse it.
+
+### CLI interface
+
+```
+kaizen-agentic schedule init [--target PATH] [--timezone TZ] [--force]
+kaizen-agentic schedule validate [--target PATH]
+kaizen-agentic schedule list [--target PATH] [--all]
+kaizen-agentic schedule prepare <agent> [--target PATH] [--format markdown|json]
+```
+
+## Boundaries
+
+- **No scheduling code** in kaizen-agentic. Cron and task creation belong to
+  activity-core; the roster query belongs to state-hub.
+- **No LLM invocation.** `prepare` produces a runner-agnostic bundle; a human or
+  automated coding-agent session executes it.
+- **State-hub schema changes** (roster opt-in flag) are designed here but
+  implemented in `the-custodian` (repo boundary).
+
+## Consequences
+
+- Operators declare per-repo schedules and a fleet roster without tribal
+  knowledge.
+- activity-core can fire recurring tasks referencing `schedule prepare`.
+- A scheduled session opens with full orientation (prompt + memory + metrics).
+- The existing `weekly-metrics-optimize` definition (ADR-004 / WP-0004) remains
+  complementary; an `optimization` agent run may chain `schedule prepare
+  optimization` then `metrics optimize`.

+## Scheduled Agent Execution
+
+Agents can run on a **regular cadence** against **preselected repos**, fired by
+**activity-core** and prepared by kaizen-agentic (ADR-005). A repo opts in by
+committing `.kaizen/schedule.yml`:
+
+```bash
+kaizen-agentic schedule init       # scaffold (coach + optimization weekly)
+kaizen-agentic schedule validate   # check schema + agent names
+kaizen-agentic schedule list       # show enabled entries
+kaizen-agentic schedule prepare coach   # orientation bundle for a scheduled run
+```
+
+`schedule prepare <agent>` bundles the agent prompt, project memory, metrics
+summary, and repo pointers — offline, no State Hub required. kaizen-agentic does
+**not** run cron or invoke Claude; activity-core fires the schedule and a
+coding-agent session executes the prepared bundle.
+
+Schema: [integrations/schedule-schema.md](integrations/schedule-schema.md).

+# activity-core Handoff — Scheduled Agent Execution (WP-0006)
+
+Coordination checklist for the **activity-core** team to enable kaizen scheduled
+agent runs. kaizen-agentic owns the schedule contract, the prepare CLI, and the
+ActivityDefinition **drafts**; activity-core owns the resolver, the schedule
+firing, and task creation (repo boundary, ADR-005).
+
+Open this as an activity-core issue/PR titled *"Enable kaizen scheduled agent
+execution (WP-0006)"* and track the boxes there.
+
+## What kaizen-agentic ships (done in this repo)
+
+- [x] `.kaizen/schedule.yml` schema + `schedule validate|init|list|prepare` CLI
+- [x] ADR-005 contract
+- [x] Resolver spec: [discover-kaizen-scheduled-repos.md](discover-kaizen-scheduled-repos.md)
+- [x] State Hub roster fields design: [state-hub-roster-fields.md](state-hub-roster-fields.md)
+- [x] Draft definitions (`enabled: false`):
+      [weekly-coach-orientation](activity-definitions/weekly-coach-orientation.md),

+- [x] Event payload spec: [kaizen-schedule-prepared-event.md](kaizen-schedule-prepared-event.md)
+
+## What activity-core must do
+
+- [ ] **Implement resolver** `discover_kaizen_scheduled_repos` per the spec
+      (hub roster ∩ repos with valid `.kaizen/schedule.yml`).
+- [ ] **Add resolver unit tests** using the four fixtures in the spec.
+- [ ] **Copy definitions** from `docs/integrations/activity-definitions/`
+      (`weekly-coach-orientation.md`, `weekly-optimization-review.md`) into the
+      activity-core catalog path (per ACT-ADR-002).
+- [ ] **Register** each definition slug in the activity-core index.
+- [ ] **Run** `make sync-activity-definitions` in activity-core.
+- [ ] **Wire cron** triggers (Mon 09:00 / 10:00 Europe/Berlin) to the resolver.
+- [ ] **Smoke test** against a pilot repo (see below) with the definition still
+      `enabled: false` (dry-run task creation).
+- [ ] **Enable gradually** — flip one definition to `enabled: true` in staging
+      after the smoke test passes.
+- [ ] **Verify runner prerequisites** — `kaizen-agentic` on PATH and the Gitea
+      PyPI extra index if the runner installs from registry (see
+      [PACKAGE_RELEASE.md](../PACKAGE_RELEASE.md)).
+
+## State Hub team (the-custodian)
+
+- [ ] Optional: add `kaizen_schedule_enabled` repo flag + `GET /repos/` filter
+      (v2 pre-filter; the repo file remains the source of truth).
+
+## Smoke test (manual, runner-agnostic)
+
+```bash
+cd /path/to/pilot-repo
+kaizen-agentic schedule init            # if not already present
+kaizen-agentic schedule validate        # exit 0
+kaizen-agentic schedule list            # shows coach + optimization enabled
+kaizen-agentic schedule prepare coach   # non-empty orientation bundle
+```
+
+Then in activity-core: run the resolver (dry-run) and confirm one
+`scheduled_run` per enabled `(repo, agent)` with a correct `prepare_command`.
+
+## Pilot roster

+
+Every Monday 09:00 Berlin time, opens a coach orientation task for each

+
+The resolver `discover_kaizen_scheduled_repos` (see

+returns one `scheduled_run` per `(repo, agent)`; this definition selects the

+```
+
+**CLI mapping:** `kaizen-agentic schedule prepare coach` (offline-safe; reads

+
+**Activation:** sync into activity-core via `make sync-activity-definitions`
+after the `discover_kaizen_scheduled_repos` resolver is enabled. Keep
+`enabled: false` until a manual smoke test passes on a pilot repo. See

+# Weekly Kaizen Optimization Review
+
+Every Monday 10:00 Berlin time, opens an optimization-agent review task for each
+schedule-eligible repo whose `.kaizen/schedule.yml` enables the `optimization`
+agent. Chains the agent orientation with the existing metrics optimizer so the
+review is evidence-backed.
+
+```rule

+bind_as: r

+
+**CLI mapping:** `kaizen-agentic schedule prepare optimization` then
+`kaizen-agentic metrics optimize`.
+
+**Complementarity:** this generalizes the metrics-only
+[weekly-metrics-optimize](weekly-metrics-optimize.md) definition into a full
+agent run. Repos may run either; running both duplicates the optimizer step.
+
+**Activation:** sync into activity-core via `make sync-activity-definitions`

+# Resolver Spec: `discover_kaizen_scheduled_repos`
+
+**Status:** specification — **implemented in activity-core**, not here. This doc
+is the contract an activity-core implementer needs to add the context resolver
+that feeds the scheduled-agent ActivityDefinitions (ADR-005).
+
+## Purpose
+
+Given the fleet roster and per-repo schedule manifests, emit one entry per
+`(repo, agent)` that is due to run, so ActivityDefinitions can `for_each` over
+the result.
+
+## Signature
+
+```
+discover_kaizen_scheduled_repos(
+    domain: str | None = None,        # optional scope filter, e.g. "custodian"
+    cadence: str | None = None,       # optional: "daily" | "weekly" | "monthly"
+    now: datetime | None = None,      # injection point for testing
+) -> { "scheduled_runs": list[ScheduledRun] }
+```
+
+Bound in a definition as:
+
+```yaml
+context_sources:
+  - type: resolver
+    query: discover_kaizen_scheduled_repos
+    params:
+      domain: custodian
+      cadence: weekly
+    bind_to: context.scheduled_runs
+```
+
+## Inputs (sources, in order)
+
+1. **State Hub** `GET /repos/` (optionally filtered by `domain` and, when the v2
+   flag lands, `kaizen_schedule_enabled=true`). Yields `slug`, `host_paths`,
+   `domain`.
+2. **Repo checkout** at `host_paths[<runner-host>]`: read
+   `.kaizen/schedule.yml`. Skip repos without the file.
+3. **Validation**: run the equivalent of `kaizen-agentic schedule validate`.
+   Skip (and log) repos whose schedule is invalid — never emit a bad entry.
+
+## Output shape
+
+```json
+{
+  "scheduled_runs": [
+    {
+      "repo": "kaizen-agentic",
+      "root": "/home/worsch/kaizen-agentic",
+      "agent": "coach",
+      "cadence": "weekly",
+      "cron": "0 9 * * 1",
+      "timezone": "Europe/Berlin",
+      "enabled": true,
+      "prepare_command": "kaizen-agentic schedule prepare coach --target /home/worsch/kaizen-agentic"
+    }
+  ]
+}
+```
+
+### `ScheduledRun` fields
+
+| Field | Source | Notes |
+|-------|--------|-------|
+| `repo` | hub `slug` | becomes `target_repo` on the created task |
+| `root` | `host_paths[<host>]` | absolute checkout path on the runner |
+| `agent` | schedule.yml key | |
+| `cadence` | schedule.yml | |
+| `cron` | schedule.yml or definition default | per-repo override when present |
+| `timezone` | schedule.yml or definition default | |
+| `enabled` | schedule.yml (`true` only emitted) | disabled entries are filtered out |
+| `prepare_command` | derived | exact CLI the task should run |
+
+## Filtering rules
+
+- Emit only entries with `enabled: true`.
+- When `cadence` param is set, emit only matching entries (lets each cron-bound
+  definition select its own cadence slice).
+- When `cron` is present on the entry, it is the authoritative per-repo time;
+  otherwise the definition's cron applies.
+
+## Errors
+
+| Condition | Behavior |
+|-----------|----------|
+| Repo unreachable / path missing on host | Skip + log `repo_unreachable` |
+| `.kaizen/schedule.yml` absent | Skip silently (not opted in) |
+| schedule.yml invalid | Skip + log `schedule_invalid` with validation errors |
+| Hub unreachable | Fail the resolver run (no roster = no safe output) |
+
+The resolver must be **idempotent** and **side-effect free**: it reads, it does
+not write. Task creation happens in the ActivityDefinition rule, not here.
+
+## Test fixtures
+
+- A repo with valid `.kaizen/schedule.yml` (coach enabled) → one entry.
+- A repo with the file but coach `enabled: false` → no entry.
+- A repo without the file → no entry.
+- A repo with an invalid schedule → no entry + logged error.

+# Event Payload: `kaizen.schedule.prepared`
+
+**Status:** design — for **future event-driven runs**. v1 of WP-0006 is
+cron-driven (activity-core fires the schedule). This event lets a runner or
+activity-core react when a `schedule prepare` bundle has been assembled, without
+polling.
+
+kaizen-agentic does **not** publish this event today; the `prepare` command
+writes to stdout. This spec fixes the contract so an emitter (a runner wrapper
+or a thin `--emit` flag in a later iteration) and consumers agree on the shape.
+
+## Subject
+
+```
+kaizen.schedule.prepared
+```
+
+NATS/event-bus subject, sibling to the existing `kaizen.metrics.recorded` and
+`kaizen.agent.installed` subjects (Pattern 2).
+
+## Payload
+
+```json
+{
+  "event": "kaizen.schedule.prepared",
+  "version": "1",
+  "occurred_at": "2026-06-17T09:00:12Z",
+  "repo": "kaizen-agentic",
+  "root": "/home/worsch/kaizen-agentic",
+  "agent": "coach",
+  "cadence": "weekly",
+  "prepare_command": "kaizen-agentic schedule prepare coach --target /home/worsch/kaizen-agentic",
+  "bundle": {
+    "format": "markdown",
+    "agent_prompt_found": true,
+    "has_memory": true,
+    "has_metrics": true,
+    "pointers": ["scope", "todo"],
+    "bytes": 8421
+  },
+  "session_close": [
+    "kaizen-agentic metrics record coach --success --time <s> --quality <0-1>"
+  ]
+}
+```
+
+### Fields
+
+| Field | Type | Notes |
+|-------|------|-------|
+| `event` | string | Always `kaizen.schedule.prepared` |
+| `version` | string | Payload schema version |
+| `occurred_at` | RFC3339 | When the bundle was assembled |
+| `repo` | string | State Hub slug |
+| `root` | string | Absolute checkout path |
+| `agent` | string | Agent the bundle orients |
+| `cadence` | string | `daily` \| `weekly` \| `monthly` |
+| `prepare_command` | string | Exact CLI that produced the bundle |
+| `bundle.format` | string | `markdown` \| `json` |
+| `bundle.agent_prompt_found` | bool | Mirrors `schedule prepare --format json` |
+| `bundle.has_memory` | bool | Memory file present |
+| `bundle.has_metrics` | bool | Metrics summary present |
+| `bundle.pointers` | string[] | Repo pointer labels found (`scope`, `todo`) |
+| `bundle.bytes` | int | Rendered bundle size |
+| `session_close` | string[] | Suggested close commands |
+
+The `bundle.*` flags map 1:1 to the JSON output of
+`kaizen-agentic schedule prepare <agent> --format json`, so an emitter can build
+this payload from the existing command without new computation.
+
+## Consumers (illustrative)
+
+- **activity-core** — close the loop: mark the scheduled task `in_progress` when
+  a bundle is prepared.
+- **artifact-store** — archive large bundles by reference.
+- **dashboards** — fleet view of which scheduled runs have been prepared vs.
+  executed.
+
+## Boundary
+
+- The payload carries **metadata and a command**, never secrets or full repo
+  contents.
+- kaizen-agentic owns the schema; emission wiring (NATS publish) is a future
+  iteration and belongs to the runner / activity-core integration.

+# `.kaizen/schedule.yml` Schema
+
+The schedule manifest declares which kaizen agents run on what cadence in an
+opted-in repo. It is the repo-local half of the scheduled-agent-execution
+contract (ADR-005). activity-core reads it (via the roster resolver) to fire
+recurring tasks; `kaizen-agentic schedule prepare` reads it indirectly by
+preparing per-agent orientation.
+
+Canonical example: [`docs/examples/.kaizen/schedule.yml`](../examples/.kaizen/schedule.yml).
+
+## Location
+
+```
+<project-root>/.kaizen/schedule.yml
+```
+
+Lives alongside `.kaizen/agents/` (memory) and `.kaizen/metrics/`. Like those,
+its presence is the **opt-in signal** for fleet scheduling.
+
+## Fields
+
+| Key | Required | Type | Default | Notes |
+|-----|----------|------|---------|-------|
+| `version` | yes | string | — | Must be `"1"` |
+| `timezone` | no | string | from ActivityDefinition | IANA tz, e.g. `Europe/Berlin` |
+| `agents` | yes | mapping | — | `agent-name → settings` |
+| `agents.<name>.cadence` | yes | enum | — | `daily` \| `weekly` \| `monthly` |
+| `agents.<name>.cron` | no | string | cadence default | 5-field cron expression |
+| `agents.<name>.enabled` | no | bool | `true` | Set `false` to declare but pause |
+
+## Example
+
+```yaml
+version: "1"
+timezone: Europe/Berlin
+agents:
+  coach:
+    cadence: weekly
+    cron: "0 9 * * 1"
+    enabled: true
+  optimization:
+    cadence: weekly
+    cron: "0 10 * * 1"
+    enabled: true
+  tdd-workflow:
+    cadence: monthly
+    enabled: false
+```
+
+## Validation
+
+```bash
+kaizen-agentic schedule validate
+```
+
+Errors are emitted with actionable messages and a non-zero exit code:
+
+- Missing or non-`"1"` `version`.
+- `agents` not a mapping, or no agents declared.
+- An agent name that is **not** installed or packaged (typo guard).
+- A `cadence` outside `daily` / `weekly` / `monthly`.
+- Duplicate agent entries.
+
+Only agents available to the project (installed under `agents/` or packaged in
+the distribution) may appear in a schedule.
+
+## Scaffolding
+
+```bash
+kaizen-agentic schedule init                 # defaults: coach + optimization weekly
+kaizen-agentic schedule init --timezone UTC  # override timezone
+kaizen-agentic schedule init --force         # overwrite existing
+```
+
+The default scaffold enables `coach` and `optimization` weekly and declares
+`tdd-workflow` monthly but **disabled** (operator opts in deliberately).
+
+## Listing
+
+```bash
+kaizen-agentic schedule list        # enabled entries only
+kaizen-agentic schedule list --all  # include disabled
+```
+
+## Relationship to activity-core
+
+The `cron` field is an **optional per-repo override**. When omitted, the cadence
+maps to the default cron declared in the matching ActivityDefinition (e.g.
+`weekly-coach-orientation` fires Mon 09:00). This keeps fleet-wide timing in one
+place while letting individual repos shift their slot.
+
+See [ADR-005](../adr/ADR-005-scheduled-agent-execution.md) and
+[INTEGRATION_PATTERNS.md Pattern 2](../INTEGRATION_PATTERNS.md).

+# State Hub Roster Fields for Kaizen Scheduling (Design)
+
+**Status:** design only — implemented in `the-custodian/state-hub`, not here
+(repo boundary). This document specifies what kaizen-agentic and activity-core
+need from the hub so the State Hub team can add the fields and filter.
+
+## Problem
+
+activity-core's resolver needs to answer: *which registered repos participate in
+kaizen fleet scheduling, and where do they live on disk?* Today state-hub knows
+the canonical repo list and `host_paths` but has no notion of schedule opt-in.
+
+## Existing hub data (sufficient for v1)
+
+`GET /repos/` already returns, per repo:
+
+| Field | Use |
+|-------|-----|
+| `slug` | Canonical repo identifier (`target_repo` in tasks) |
+| `host_paths[hostname] → local_path` | Where the repo is checked out on a runner |
+| `domain` | Scope filter (e.g. `custodian`) |
+
+For **v1**, opt-in is detected **in the repo** (`.kaizen/schedule.yml` exists and
+validates). The resolver clones/reads each candidate path and checks for the
+file. No hub schema change is strictly required to ship the pilot.
+
+## Proposed hub fields (v2, optional)
+
+To let operators query eligibility **without touching every checkout**, add an
+optional repo-metadata flag:
+
+| Field | Type | Default | Meaning |
+|-------|------|---------|---------|
+| `kaizen_schedule_enabled` | bool | `false` | Operator-confirmed fleet participation |
+| `kaizen_schedule_updated_at` | timestamp | null | Last time schedule.yml was synced/seen |
+
+### Suggested filter
+
+```
+GET /repos/?kaizen_schedule_enabled=true&domain=custodian
+```
+
+Returns only schedule-eligible repos with their `host_paths`, so the resolver
+skips repos that have not opted in — cheaper than scanning every checkout.
+
+### Write path
+
+The flag is set by an operator (or a future `kaizen-agentic schedule register`
+that calls the hub). It is **advisory**: the authoritative opt-in remains the
+presence of a valid `.kaizen/schedule.yml` in the repo, re-checked by the
+resolver at run time. The flag is an index, not a source of truth.
+
+## Boundary
+
+- kaizen-agentic does **not** write these fields in WP-0006.
+- state-hub schema migration is tracked in `the-custodian`.
+- The resolver (activity-core) treats the hub flag as a pre-filter and the repo
+  file as the decision.
