docs: add BRIDGE-WP-0002 OpsCatalog extension workplan

7-phase plan covering catalog data models, loader, validator, bridge
resolver (inline-first with catalog fallback), bridge targets and
bridge catalog CLI commands, and integration tests. 16 tasks registered
in Custodian State Hub (workstream bridge-wp-0002). Covers OpsCatalog
FRS FR-1–15 and OpsBridge FRS FR-21–23.

# BRIDGE-WP-0002 — OpsCatalog Extension
**Scope:** Implement OpsCatalog as a Git-backed YAML knowledge repository and
integrate it with the `bridge` CLI.
**Depends on:** BRIDGE-WP-0001 complete (bridge CLI operational).
**Out of scope:** Identity provider integration (FR-2729, deferred indefinitely).
---
## Goal
Deliver the OpsCatalog subsystem: a structured YAML catalog of operations
domains, targets, bridges, and actor classes stored in a Git repository.
OpsBridge loads the catalog at runtime to resolve bridge identifiers, orient
operators, and expose the `bridge targets` and `bridge catalog` commands.

loader.py # walk catalog_path, parse YAML files into typed objects
models.py # CatalogDomain, CatalogTarget, CatalogBridge, ActorClass
validator.py # validate catalog entries against schemas
resolver.py # resolve tunnel name → CatalogBridge → TunnelConfig
```
**Integration points with existing bridge code:**
- `config.py`: read `catalog_path` from `tunnels.yaml`; pass to catalog loader
- `manager.py`: use `resolver.py` to look up bridge config from catalog when
tunnel is not defined inline in `tunnels.yaml`
- `cli.py`: add `bridge targets` and `bridge catalog` commands

---
## Phase 1 — Catalog Data Models
**Acceptance:** All catalog YAML types parse into typed Python objects.
### T01 — Define catalog dataclasses in catalog/models.py
```task
id: BRIDGE-WP-0002-T01
state_hub_task_id: 21b90574-a27c-467c-8e9d-d4029a659171
status: todo
priority: high
```
Define `CatalogDomain`, `CatalogTarget`, `CatalogBridge`, `ActorClass` dataclasses.
`CatalogBridge` must be mergeable with `TunnelConfig` (catalog supplies defaults;
inline `tunnels.yaml` entries can override).
---
## Phase 2 — Catalog Loader (FR-14)
**Acceptance:** `catalog.load(path)` returns a populated `Catalog` object from a
directory tree; unknown `type:` values are skipped with a warning.
### T02 — Implement catalog/loader.py
```task
id: BRIDGE-WP-0002-T02
state_hub_task_id: 782b5b4d-1f3f-4e5d-ad46-dc57b345bda3
status: todo
priority: high
```
Walk `catalog_path` recursively, parse every `*.yaml` file, dispatch on `type:`
field. Build in-memory index: domains, targets, bridges, actors.
### T03 — Unit tests for catalog loader
```task
id: BRIDGE-WP-0002-T03
state_hub_task_id: 41fed4f8-7818-4ca1-bb48-6ac1089220e8
status: todo
priority: medium
```
Test: full catalog directory fixture loads correctly; missing required field raises
clear error; unknown type is skipped; empty catalog returns empty index.
---
## Phase 3 — Catalog Validation (FR-15)
**Acceptance:** `bridge catalog validate` exits non-zero and prints all violations
when the catalog contains invalid entries.
### T04 — Implement catalog/validator.py
```task
id: BRIDGE-WP-0002-T04
state_hub_task_id: 32946d15-5516-4599-8f27-8c653dec6786
status: todo
priority: medium
```
Validate required fields per type. Cross-reference checks: target's `domain` must
exist; target's `reachable_via` bridge IDs must exist; bridge's `target` and
`domain` must exist; actor referenced by bridge must exist.
### T05 — Unit tests for catalog validation
```task
id: BRIDGE-WP-0002-T05
state_hub_task_id: 6061a6eb-9966-4be9-aa5e-ea7edf7fd085
status: todo
priority: medium
```
Test: valid catalog passes; dangling `reachable_via` reference fails; missing
required field fails.
---
## Phase 4 — Bridge Resolver (FR-2 integration)
**Acceptance:** `bridge up state-hub-coulombcore` resolves the bridge config from
the catalog when no inline entry exists in `tunnels.yaml`.
### T06 — Implement catalog/resolver.py
```task
id: BRIDGE-WP-0002-T06
state_hub_task_id: a92d97c8-4eec-4dd5-9b90-d9c1cba813ac
status: todo
priority: high
```
`resolve(name, catalog, inline_config) → TunnelConfig`. Lookup order: inline
`tunnels.yaml` entry wins; fall back to catalog bridge by ID. Merge catalog
bridge fields into `TunnelConfig`. Raise `BridgeNotFound` if neither source
has the name.
### T07 — Integrate resolver into config.py and manager.py
```task
id: BRIDGE-WP-0002-T07
state_hub_task_id: 23799377-64f2-4c13-aa72-364770d80f91
status: todo
priority: high
```
Read `catalog_path` from `tunnels.yaml` (optional; catalog disabled if absent).
Pass resolved `TunnelConfig` to `TunnelManager` unchanged — manager stays
catalog-unaware.
### T08 — Unit tests for resolver
```task
id: BRIDGE-WP-0002-T08
state_hub_task_id: d2313182-975f-409f-9d4f-ebabf66b44df
status: todo
priority: medium
```
Test: inline entry takes precedence; catalog fallback works; inline overrides
catalog fields; missing name raises `BridgeNotFound`.
---
## Phase 5 — CLI: bridge targets (FR-21, FR-22, FR-23)
**Acceptance:** `bridge targets` prints a table of domains, targets, and which
bridges provide access to each target.
### T09 — CLI: bridge targets command
```task
id: BRIDGE-WP-0002-T09
state_hub_task_id: f9e508db-a19f-42be-9437-b4bdeb00a534
status: todo
priority: medium
```
Table columns: `DOMAIN`, `TARGET`, `KIND`, `BRIDGES`. `--domain <name>` filter.
`--json` flag for automation. Requires catalog to be configured; clear error if
`catalog_path` not set.
### T10 — CLI: bridge targets show <target>
```task
id: BRIDGE-WP-0002-T10
state_hub_task_id: e288a1d3-d676-404a-a3eb-25dbb241502d
status: todo
priority: low
```
Show full metadata for a single target: domain, kind, description, reachable_via
bridges, and any operations notes from `docs/*.md` files in the domain directory.
---
## Phase 6 — CLI: bridge catalog commands
**Acceptance:** Operators can inspect and validate the catalog from the CLI.
### T11 — CLI: bridge catalog list
```task
id: BRIDGE-WP-0002-T11
state_hub_task_id: 73899b70-b0ac-4f48-b362-cc2455a66f41
status: todo
priority: medium
```
List all domains and a count of targets and bridges per domain.
### T12 — CLI: bridge catalog validate
```task
id: BRIDGE-WP-0002-T12
state_hub_task_id: e091daa2-7c20-4169-b634-1fcc469513ea
status: todo
priority: medium
```
Run `validator.py` and print all violations. Exit 0 if clean, 1 if violations
found. Useful in CI pipelines for the catalog repo.
### T13 — CLI: bridge catalog show <bridge-id>
```task
id: BRIDGE-WP-0002-T13
state_hub_task_id: 9f5f4f30-bfe6-40fd-b178-2fbb396816ee
status: todo
priority: low
```
Print full resolved bridge metadata including target and domain context.
---
## Phase 7 — Integration Tests
**Acceptance:** `uv run pytest` passes cleanly with catalog fixtures.
### T14 — Integration test: catalog load and resolve
```task
id: BRIDGE-WP-0002-T14
state_hub_task_id: 5ccb2b4b-7ea5-4c38-8246-d59b8f7d4419
status: todo
priority: medium
```
Fixture: minimal catalog directory with one domain, one target, one bridge.
Test `bridge up <catalog-bridge-name>` resolves and starts tunnel.
### T15 — Integration test: bridge targets output
```task
id: BRIDGE-WP-0002-T15
state_hub_task_id: 72c9f686-c474-46c4-a759-bfd47e2d4211
status: todo
priority: medium
```
Test `bridge targets` output matches catalog fixture. Test `--json` flag.
### T16 — Integration test: bridge catalog validate
```task
id: BRIDGE-WP-0002-T16
state_hub_task_id: 83c0734e-0dc2-49ce-8b6a-a4d5e26ff33a
status: todo
priority: medium
```
Test clean catalog exits 0; catalog with a dangling reference exits 1 with a
clear message.

*FR-2729 (identity integration) remain deferred — require external identity
provider infrastructure.*
---
## Deferred
- **FR-2729** — Identity provider integration (privacyIDEA / SSH CA) — separate
workplan when identity infrastructure is available.
- **Operations notes search** — full-text search across `docs/*.md` files — nice
to have, not required for MVP.
