# KONT-WP-0013: CMIS Browser Binding TCK Compatibility
## Purpose
Turn the current CMIS-inspired adapter into a CMIS 1.1 Browser Binding surface
that Apache Chemistry OpenCMIS can connect to and assess. The immediate goal is
not full CMIS certification; it is to pass session creation and then drive
repository/type plus object/content behavior from real TCK evidence.
## Trigger
The 2026-05-08 live `guide-board` + `open-cmis-tck` run reached the endpoint,
but OpenCMIS failed before semantic test cases could execute:
```text
Found invalid Repository Info!
```
The result is persisted in
`docs/cmis-opencmis-tck-assessment-2026-05-08T063312Z.md`.

## Boundary
This workplan fixes Browser Binding compatibility for the profiled CMIS
connector. It must not turn CMIS into a second domain model. Native engine DTOs,
policy, blob handling, audit, and repository services remain authoritative; the
CMIS layer translates those capabilities into standard protocol shapes.
AtomPub and Web Services remain unsupported by design. Mutating multifiling,
PWC/versioning services, broad CMIS SQL, ACL mutation, policies, renditions,
retention/hold, and bulk updates remain out of scope unless a later workplan
adds them explicitly.
## Desired Outcome
- OpenCMIS Browser Binding session creation succeeds against `compat-tck`.
- Repository/type TCK group executes and produces parsed cases instead of an
infrastructure/protocol blocker.
- Object/content TCK group executes far enough to expose true semantic gaps.
- Internal CMIS route tests pass with service dependencies installed.
- Updated CMIS scorecard separates TCK-backed compatibility from native
controlled-client usefulness.
## F13.1 - Define Browser Binding protocol contract examples
```task
id: KONT-WP-0013-T001
status: todo
priority: high
state_hub_task_id: "fa2f99fb-51ed-4fba-8f36-ba4b790908e5"
```
Acceptance:
- Repository service document/repository-info examples are documented in the
exact shape expected by OpenCMIS Browser Binding.
- Required field names, capability names, repository ID handling, root folder
ID handling, and service URLs are covered.
- The examples include at least one valid `compat-tck` repository response and
one invalid native-shaped response used as a negative preflight fixture.
## F13.2 - Implement CMIS Browser Binding serializers
```task
id: KONT-WP-0013-T002
status: todo
priority: high
state_hub_task_id: "39949f5b-32bb-4ec7-b0f6-83a16ce443b7"
```
Acceptance:
- Repository info, capabilities, type definitions, object envelopes, property
maps, content stream descriptors, ACL projections, and change entries are
emitted through CMIS protocol serializers.
- Native snake_case DTOs are no longer exposed directly on Browser Binding
compatibility routes.
- Serializer tests assert CMIS field names such as `repositoryId`,
`repositoryName`, `cmisVersionSupported`, and `rootFolderId`.
## F13.3 - Align target repository identity and access-point profile
```task
id: KONT-WP-0013-T003
status: todo
priority: high
state_hub_task_id: "96e11fe6-68c6-46ce-88b8-bda0b9baf2d5"
```
Acceptance:
- The `compat-tck` access point and `open-cmis-tck` target profile agree on the
repository ID.
- If an alias is needed, it is explicit, deterministic, and documented.
- The port/profile assumptions for local TCK runs are documented without
relying on accidental services already bound to port `8000`.
## F13.4 - Add protocol-shape preflight gates
```task
id: KONT-WP-0013-T004
status: todo
priority: high
state_hub_task_id: "06506455-b3c3-4f17-ae8a-8ffebc226f73"
```
Acceptance:
- `open-cmis-tck` preflight fails native-shaped repository info before invoking
Maven.
- The failure is classified as target protocol shape incompatibility, not a
generic infrastructure error.
- The preflight reports actionable missing or misshaped fields.
## F13.5 - Fix OpenAPI generation for streaming routes
```task
id: KONT-WP-0013-T005
status: todo
priority: medium
state_hub_task_id: "de73a3ff-ddf9-40bb-b89c-50d6fabdb841"
```
Acceptance:
- `/openapi.json` renders successfully with CMIS byte-stream routes enabled.
- The route still returns a real streaming response at runtime.
- `tests/cmis/test_cmis_browser_binding_api.py::test_cmis_browser_binding_routes_are_advertised_in_openapi`
passes with service dependencies installed.
## F13.6 - Resolve navigation contract and root children behavior
```task
id: KONT-WP-0013-T006
status: todo
priority: medium
state_hub_task_id: "1cf8d36c-6127-46cd-b409-dda7a045b8dd"
```
Acceptance:
- Root folder behavior is explicitly defined for Browser Binding compatibility.
- Tests cover root children, synthetic folder children, projected parents, and
hidden object filtering.
- Internal route tests and OpenCMIS expectations do not disagree about whether
root returns only folders or direct documents.
## F13.7 - Establish OpenCMIS session smoke test
```task
id: KONT-WP-0013-T007
status: todo
priority: high
state_hub_task_id: "38777aea-7d2d-4b30-99b4-5194f2c2f8b0"
```
Acceptance:
- A fast smoke check proves that OpenCMIS can list repositories and retrieve
repository info before full TCK groups run.
- The smoke check is captured by `guide-board`/`open-cmis-tck` artifacts.
- Failure messages preserve the underlying OpenCMIS exception.
## F13.8 - Rerun repository/type TCK group to parsed-case evidence
```task
id: KONT-WP-0013-T008
status: todo
priority: high
state_hub_task_id: "8e7b2235-d39a-465a-b828-b05eb6bcfce3"
```
Acceptance:
- `repository-type` no longer exits at session creation.
- Basics and Types test cases are parsed and mapped into normalized evidence.
- Any semantic failures become concrete follow-up tasks with capability labels.
## F13.9 - Rerun object/content TCK group and classify gaps
```task
id: KONT-WP-0013-T009
status: todo
priority: high
state_hub_task_id: "22af3e39-c217-4f6b-b54a-5ecea3894020"
```
Acceptance:
- `object-content` reaches parsed TCK cases.
- Failures are separated into supported-fix, unsupported-by-design, and profile
expectation categories.
- Content stream read/write behavior is tested against both internal route
tests and OpenCMIS expectations.
## F13.10 - Update scorecard and compatibility documentation
```task
id: KONT-WP-0013-T010
status: todo
priority: medium
state_hub_task_id: "469a3ea6-a6ab-4e6e-ba4f-5b1abdabd6c4"
```
Acceptance:
- `docs/cmis-1-1-capability-scorecard.md` is updated from TCK-backed evidence.
- The scorecard separates broad CMIS client compatibility from controlled
native-profile usefulness.
- Deployment docs explain which CMIS clients are expected to work and which
capabilities are honestly unsupported.
## Definition Of Done
- Focused internal CMIS tests pass with service dependencies installed.
- OpenCMIS can establish a Browser Binding session against `compat-tck`.
- Repository/type TCK group produces parsed evidence.
- Object/content TCK group produces parsed evidence or documented
unsupported-by-design gaps.
- Updated documentation clearly states the evidence-backed CMIS posture.
