docs(integrations): INT-1 discovery gate records and capability-matrix checker

[erichare]

Summary

Discovery gate (INT-1) for Dedicated Integrations 1.13 (Jira LE-2398). This PR is the reviewable home for the gate outputs. The design artifacts and release-owner decisions are complete; the gate remains open until the lfx, langflow-base, Enterprise, frontend, hosted-app, product, and platform owner sign-off rows are filled.

• design/dedicated-integrations/: sourced capability matrices for Google Workspace (5 actions), Microsoft 365/Teams (8), and Slack (7); decision records; the INT-2 connection contract; frontend and operator surfaces; deferred trigger findings; and the re-issued 48.75 engineer-week estimate.
• Desktop OAuth registrations default to Langflow-owned public clients (decisions/desktop-oauth-ownership.md, accepted 2026-09-02): a Google Desktop client in the hosted project, the Entra desktop platform with public client flows on the hosted registration, and a second PKCE-enabled Slack app. Customer-owned registrations remain the override, as on self-managed. Only who registers the provider app varies by context; the broker, callback route, and connection contract are one design.
• Slack 1.13 is Web API throughout. MCP is deferred to 1.14 because the gate has no dated authenticated tools/list capture that freezes the exact tool ids and schemas required by the plan.
• The capability contract now supports multiple named auth profiles per provider, explicit OAuth client type per deployment context, and structured conditional-scope predicates tied to declared action inputs.
• scripts/ci/check_capability_matrices.py validates the JSON Schema, evidence and decision invariants, conditional-scope references, sign-off coverage, and gate-close completion. --require-accepted now requires nonblank Name, Date, and PR cells in both aggregate and record-level sign-off tables.

No provider code, tables, routes, or UI are implemented here. Those remain INT-2 through INT-14.

Phases

Phase	Deliverable	Status
0-2	scaffold, checker, and three sourced matrices	done
3	substrate decisions	accepted: Google SDK, Microsoft REST, Slack REST; Slack MCP deferred
4	Google restricted-scope decision	accepted: avoid; Gmail search excluded, Drive on drive.file
5	connection-contract.md	drafted; owner sign-offs pending
6	KB connector and palette naming decisions	accepted
7	frontend and operator surface inventory	drafted; owner sign-off pending
8	estimate and gate-close enforcement	48.75 engineer-weeks; gate-close correctly blocked on signatures
+	Desktop OAuth registration ownership (2026-09-02)	accepted: Langflow-owned public clients on Desktop, customer-owned override; INT-5 +0.25

Test plan

• uv run pytest scripts/ci/test_capability_matrices.py — 36 passed
• uv run python scripts/ci/check_capability_matrices.py — exits 0
• uv run python scripts/ci/check_capability_matrices.py --require-accepted — exits 1 only for the unsigned owner rows, as intended
• Ruff check and format clean; pre-commit hooks passed, including secret detection
• Every declared owner sign-off row is filled in the README and the corresponding record
• --require-accepted exits 0 after those signatures are recorded

Summary by CodeRabbit

• Documentation

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 105b4

The PR adds discovery-gate contracts and accepted integration decisions, but the current documents still contain credential authorization and collision risks, a Desktop authentication mismatch for Slack actions, and incomplete owner sign-off tracking. These issues can misdirect implementation or permit unsafe credential behavior, so the PR is not merge-ready until corrected or explicitly accepted.

Full details: Docstring Coverage

Explanation

Docstring coverage is 13.16% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 38 functions across 2 files. (17 skipped: 17 unsupported.)

Full details: Test Coverage For New Implementations

Explanation

The PR adds corresponding tests for the new checker. scripts/ci/test_capability_matrices.py follows the repository naming convention and contains 16 substantive tests. The tests validate the checked-in Google, Microsoft, and Slack matrices, workflow path coverage, schema/checker enum consistency, action caps, scope classification and sourcing, restricted-scope decisions, confidence rules, malformed or missing files, provider coverage, and --require-accepted behavior. The CI workflow runs python -m pytest scripts/ci/ -v, which includes this test module. The PR adds no provider runtime or frontend implementation that would require additional tests.

Full details: Test Quality And Coverage

Explanation

The new tests use pytest and contain meaningful positive and negative checks, but they do not comprehensively cover the new checker. The implementation adds validation for top-level and action required fields, enums, dates, source records, verification programs, decision records, deployment contexts, duplicate and unexpected matrices, sourced action blocks, and CLI exit behavior. The 16 tests cover only selected cap, scope, confidence, future-date, file-error, provider-missing, and draft-record cases. They do not exercise most of those validation paths. Async, frontend, and API-endpoint checks are not applicable to this PR.

Resolution

Add pytest cases for each checker validation family, including malformed or incomplete top-level and action objects, invalid enums and dates, invalid source and verification-program records, missing or malformed substrate and restricted-scope decisions, invalid action IDs/components/contexts, missing included-action fields, unsourced claim blocks, unknown verification dependencies, duplicate and unexpected matrices, and both successful and failing main() CLI invocations including --require-accepted. Add schema validation tests beyond enum equality, or explicitly test the supported schema/checker contract.

Full details: Test File Naming And Structure

Explanation

The pull request adds or modifies frontend test files that do not use Playwright. The seven src/frontend/src/**/__tests__/*.test.ts/.test.tsx files use Jest and @testing-library/react (jest.mock, describe, and it). src/frontend/jest.config.js runs these files with Jest, while src/frontend/playwright.config.ts only targets src/frontend/tests. The added src/frontend/tests/core/regression/autosave-on-open.spec.ts does use Playwright, and the backend tests use the required test_*.py names with pytest-style functions. The changed tests also include positive, negative, malformed-input, and missing-file cases. The explicit frontend runner requirement is still not met.

Resolution

Port the changed frontend tests to Playwright tests, use @playwright/test fixtures and assertions, and place them under the configured Playwright test directory with the required .test.ts or .test.tsx names. Do not leave the changed Jest/Testing Library suites classified as frontend tests for this check.

Full details: Excessive Mock Usage Warning

Explanation

No excessive mock usage is present. The pull request adds one test file, scripts/ci/test_capability_matrices.py; it has no unittest.mock, Mock, MagicMock, patch, monkeypatch, or mocker usage. Tests use real JSON files, Path, shutil.copytree, and temporary directories to exercise the checker and workflow data. No changed test file replaces core behavior with mocks, so this check has no failure condition.

Extract the workflow path helpers into a shared module. The two implementations have already diverged: test_execution_principal_matrix.py supports ? and gives quoted-entry assertion errors, while test_capability_matrices.py does neither. Sharing the helpers prevents further drift and provides a clear error for unquoted filters.

Add JSON Schema validation to validate_matrix. The checker applies only hand-written rules, so schema constraints such as additionalProperties, nested field patterns, and minLength remain unenforced. _decision_record_errors joins unchecked paths with design_root; a value such as ../../README.md can resolve outside the design root. Add jsonschema to the CI install step when using the library.

Inline comments:
In `@design/dedicated-integrations/connection-contract.md`:
- Line 52: Update ConnectionRef.env_key() so distinct connection names remain
injectively encoded: do not map both hyphens and underscores to the same
character. Either encode them distinctly or reject hyphens consistently with
validation, and add a collision test covering names such as work-a and work_a.
- Around line 183-186: Update the CredentialLease contract to explicitly define
expires_at=None as a non-expiring credential path, avoiding refresh calculations
that subtract from None during token access. Specify the expected behavior and
add coverage confirming headless credentials remain valid without expiry or
refresh handling.
- Around line 254-257: Update OAuthProfile.kind in the IntegrationProvider
contract to explicitly represent device code, service account, domain-wide
delegation, and bot install authentication modes alongside the existing kinds.
Align the values with the documented authentication-mode matrix so every
supported flow has a provider-manifest mapping.
- Around line 177-181: Update connection handle resolution in resolve() so it
does not call VariableService.get_variable() or consume arbitrary request-scoped
global_vars. Read handles only from a connection-specific source, or enforce the
connection-provisioning permission before resolving them, while preserving the
existing environment fallback behavior where authorized.

In `@design/dedicated-integrations/decisions/palette-naming.md`:
- Around line 51-55: Update
design/dedicated-integrations/decisions/palette-naming.md lines 51-55 to keep
Gmail folded into the Google group and name the Microsoft group “Microsoft 365”;
update design/dedicated-integrations/frontend-surfaces.md lines 20-21 in A7 to
match those decisions and add the Microsoft icon to A8.

In `@design/dedicated-integrations/decisions/substrate-google.md`:
- Line 5: Update the decision scope statement and wave-1 action list to cover
only the five Google actions included in
design/dedicated-integrations/README.md, explicitly excluding Gmail search; do
not leave the scope as “all actions.”

In `@design/dedicated-integrations/decisions/substrate-slack.md`:
- Around line 54-56: Update the Slack integration decision around “Desktop
exposes user-identity actions only” so Desktop user actions are routed through
the Web API, unless a documented confidential-client broker and fallback is
added. Do not keep Desktop slack.user.* actions assigned directly to the
official Slack MCP server without that confidential-client flow; preserve MCP
only for supported surfaces.

In `@design/dedicated-integrations/estimate.md`:
- Around line 1-3: Align the estimate heading with the table and the statement
that the original estimate includes INT-1: change the “INT-2 through INT-14”
scope in the heading to include INT-1, preserving the INT-1 Discovery gate row
and consistent total scope.

In `@design/dedicated-integrations/matrices/google.json`:
- Line 653: Update the substrate_notes entry for google.drive.fetch to state
that the Workspace Drive MCP server requests the same drive.file scope, matching
the action’s configured scope and the parallel integration note.

In `@design/dedicated-integrations/matrices/microsoft.json`:
- Around line 1042-1061: Update the scope list for microsoft.files.fetch to
include Sites.Read.All, matching the site_id input and the corresponding site
path supported by microsoft.files.list; preserve the existing scope entries and
metadata format.

In `@design/dedicated-integrations/README.md`:
- Around line 35-40: Update the ownership/sign-off table to include
kb-oauth-connector-adoption.md for both the lfx owner and langflow-base owner
rows, and google-restricted-scopes.md for the langflow-base owner row. Ensure
the accepted records have the required non-release sign-off entries populated,
or apply an explicitly defined alternative acceptance rule.
- Line 60: Update the directory map fenced code block in the README to use the
text language tag, changing the opening fence to ```text so it satisfies the
MD040 requirement.
- Line 27: Update the gate-close command in the README to invoke
check_capability_matrices.py through uv run instead of python, matching the
runnable commands below.

Second review round, applied in 32bee29 (32bee29). All three findings were reproduced before fixing.

Scope alternatives modeled as simultaneously required. Agreed. The schema's scope entry gains role (required, optional, alternative) and condition, every scope in the three matrices is tagged, and connection-contract.md section 8 states how required_scopes and optional_scopes are lifted from the roles. The open Microsoft permission questions on included actions are decided rather than carried: Mail.Read, Calendars.Read, and Files.Read are the wave-1 profiles, the wider Files and Sites scopes are optional on drive_id and site_id, and Mail.ReadBasic is recorded as the unused alternative. Slack's search:read is the Web API alternative; users:read, groups:read, and canvases:read are optional on their inputs. The checker now requires a role on every included scope, a condition on optional and alternative scopes, no condition on required ones, and at least one required scope per included action.

Gate-close validation skipped record requirements. Agreed on all three. --require-accepted walks every record under decisions/ (TEMPLATE.md aside); a record that declares non-release owners without a sign-off table is an error, and frontend-surfaces.md and triggers-deferred.md gain their tables; a missing README is a single loud error on the CLI path instead of a silent skip.

Validate against the published JSON Schema. Agreed. Every matrix is validated with jsonschema (Draft 2020-12) before the gate rules, a missing validator is an error rather than a skip, and the CI Scripts Tests workflow installs it. outputs: [] and an unknown action field now fail.

Regression tests cover each rule (31 in the file, all passing), and both checker modes exit 0 on the branch.
