Summary

Adds Confluence-style space permissions to the Docs plugin using the RBAC primitives from the paired Mattermost core PR. Every space, page, draft, and membership route now resolves space visibility and the caller's effective permissions before acting. The plugin also adds open/private spaces, per-space defaults, per-member grants, membership management, and the corresponding web UI.

Confluence parity

The goal is parity with Confluence's space-level permission model: a default set for everyone in a space, plus additional grants for individual members.

Confluence concept Docs implementation
Default permissions for everyone in a space The scheme on the space's Mattermost backing channel
Additional permissions for an individual member Fixed core capability roles in that channel member's ExplicitRoles
Space administrator The channel member's SchemeAdmin flag, resolving to the scheme's full admin role
Space visibility ViewAccess=open for eligible team members, or ViewAccess=private for explicit members only
Site/team controls for spaces Core's read_space, create_space, manage_space, and delete_space permissions
Guest access Invited guests resolve read_page only and cannot receive additional grants

The Mattermost team is the outer visibility boundary. Anonymous access, per-group grants, and Confluence-style restrictions on individual pages are not included in this PR.

Core/plugin boundary

Mattermost core owns every piece of state used directly by an effective permission check:

  • The 11 space-related permission IDs, five fixed capability roles, three preset schemes, and their migrations and guards.
  • The active default policy in the space backing channel's SchemeId.
  • Preset and pooled schemes in core's existing Schemes and Roles tables.
  • Per-member standing in core's ChannelMembers rows: SchemeUser, SchemeAdmin, SchemeGuest, and ExplicitRoles.
  • Atomic pooled-scheme creation, role immutability, permission resolution, member-role cache invalidation, and HA consistency.

This state belongs in core because HasPermissionToChannel and channel membership updates are core services. Core can therefore give every caller and every node the same answer, enforce the role and scheme invariants at every write entry point, and keep grants synchronized with Mattermost's caches. The plugin never writes these tables directly and does not maintain a second ACL.

The Docs plugin owns the Confluence-specific product policy expressed through those primitives:

  • Selecting the default permission set and mapping it to a preset or core-pooled scheme.
  • Mapping space, page, draft, and membership operations to permission checks.
  • Open/private visibility, membership workflows, last-admin and self-escalation rules, websocket events, and UI.
  • DOCS_Space.ViewAccess and DOCS_SpaceAutoJoin in the plugin database, alongside the plugin's space and page content.

The plugin database does not mirror the effective grants. A space's defaults remain represented by the backing channel's core SchemeId; member grants and admin/guest standing remain represented by the core ChannelMembers row.

The plugin uses pluginapi for all mutations of core-owned state and for scheme reads, where core owns primary selection, generated-role validation, and aggregate consistency. Its store performs read-only relational projections across ChannelMembers, TeamMembers, and Channels for roster, discovery, websocket audience, and last-member queries. Those projections do not write core tables or replace core's effective permission checks.

This policy stays in the plugin because it is specific to Docs and Confluence parity and can evolve with that product, while the underlying authorization data and invariants must remain consistent with the rest of Mattermost.

Scheme resolution and the core-hosted pool

Every space has a ChannelTypeSpace backing channel. Its SchemeId selects the default permissions for ordinary members.

The plugin normalizes the requested default set and resolves it as follows:

  1. A set matching a core preset uses that seeded scheme directly:

    Scheme Default permissions beyond implicit read_page
    docs_space_contribute comment_page, create_page, edit_page, delete_own_page
    docs_space_comment comment_page
    docs_space_readonly none
  2. Any other set is sent to pluginapi.Scheme.GetOrCreateChannelScheme as three complete role sets:

    • user: read_page plus the configured defaults;
    • admin: all seven channel-scoped space permissions;
    • guest: read_page only.

    This non-preset path uses a custom pooled scheme, so core requires the custom-permissions-schemes entitlement regardless of which permission IDs are in the sets. Because Docs supplies a non-empty guest role, it also requires the guest-permissions entitlement. The three seeded presets are resolved by name and require neither pooled-scheme creation nor these checks.

  3. Core derives the plugin-and-content-specific identity, reuses an existing pooled scheme or creates the scheme and all three roles atomically, and returns the complete immutable scheme.

  4. The plugin points the backing channel at the returned SchemeId. Changing the defaults resolves another preset or pooled entry and repoints the channel; it never mutates a shared role. Previous pooled entries remain available for reuse.

Runtime resolution uses Scheme.GetByName for presets and the aggregate Scheme.GetForChannel for a backing channel's scheme plus guest, user, and admin roles. The aggregate includes the user role and its stored permissions, keeping the result primary-safe and internally consistent.

Permission vocabulary

read_page is the implicit floor for a space member and is not accepted as an explicit grant. admin_space is a per-member grant represented by SchemeAdmin; it cannot be part of the default set.

The other permissions can be defaults or individual grants. Individual grants map to the fixed roles seeded by core:

Permission Capability role
create_page docs_pg_create
comment_page docs_pg_cmt
edit_page docs_pg_edit
delete_own_page docs_pg_del_own
delete_page docs_pg_del

Each capability role contains read_page plus its mapped permission, so the role is self-contained. Core still requires every membership update to include the generated base scheme role. Grant requests are allowlist-validated and stored as a full replacement of the member's grant set.

Access resolution and route enforcement

  • A sysadmin can access every space.
  • Other callers must be active members of the space's team and hold read_space.
  • A backing-channel member reads through read_page on the channel.
  • An eligible non-member may read an open space through the team-level open-channel fallback. Compliance mode disables this fallback. Private spaces require explicit membership.
  • Missing spaces, non-membership, and permission denials return the same 403 response so callers cannot probe existence. Backend lookup failures remain 500 responses.
  • Guests are limited to read_page at the plugin gate even if stale explicit roles remain after a role transition.

Page and draft routes then require the operation-specific permission: create_page, edit_page, delete_own_page, or delete_page. A cross-space move requires delete authority over the source subtree and create_page on the destination; an own-delete grant verifies ownership of the entire locked subtree inside the move transaction.

Space lifecycle routes use the team-scoped permissions from core:

  • creating a space requires create_space;
  • management operations allow a space admin or a caller with manage_space who can already read the space;
  • delete and restore allow a space admin or a caller with delete_space who can already read the space;
  • changing visibility or default permissions is restricted to a space admin or sysadmin.

Visibility and membership

DOCS_Space.ViewAccess stores open or private with a database constraint and a fail-closed database default. Space creation accepts the initial visibility and defaults to open when omitted.

An eligible non-member of an open space may join through POST /spaces/{space_id}/members/me. The webapp calls this immediately before the caller's first draft write, so reading or merely opening an editor does not create a membership. The server rechecks open-space admission and current defaults under the space membership lock, then records an auto-join provenance row. A later explicit add, removal, or permission change clears that marker and makes the membership explicit.

Changing an open space to private uses the same membership lock and treats cleanup as a precondition of the visibility update:

  1. Re-read the live space, re-authorize the administrator, and reject a stale optimistic-lock baseline before removing anyone.
  2. Remove each membership still carrying auto-join provenance while the persisted space remains open. A core not-found response means the membership is already absent and its stale marker can be cleared.
  3. If a genuine removal fails, return an error and leave ViewAccess=open; the failed marker remains available for retry. Any membership removed before that failure remains safely rejoinable while the space is open and receives a websocket invalidation.
  4. Commit ViewAccess=private only after the prune completes. Deliberately invited or customized members have no marker and remain members.

This preserves the Confluence distinction between the collective “all eligible team members” grant and an individual invitation without introducing a second authorization layer or asynchronous cleanup job.

Membership APIs provide paginated listing, add/remove, and full-replacement permission updates:

  • GET/POST /spaces/{space_id}/members
  • DELETE /spaces/{space_id}/members/{user_id}
  • PUT /spaces/{space_id}/members/{user_id}/permissions
  • PUT /spaces/{space_id}/default-permissions

The service prevents self-escalation, refuses grants to guests, preserves a last space administrator, and prevents removal of the last member who can still reach a private space. Readers may see the roster; only callers with the manage tier receive the permission matrix and auto-join provenance.

Webapp and licensing

  • Space creation includes the initial visibility choice.
  • Space settings exposes open/private visibility and the default permissions for everyone in the space.
  • On a licensed server, administrators can select arbitrary default-permission combinations with the checkbox matrix; non-preset combinations use the core-hosted pooled schemes.
  • Without the custom-permissions-schemes entitlement, the arbitrary matrix is replaced by the three included presets: Contribute, Comment, and Read only. The UI explains that custom combinations require a Professional or Enterprise license rather than submitting a request that core will reject.
  • The member matrix shows effective permissions separately from additional per-member grants.
  • Guest rows are locked because the server permits read-only access only.
  • Permission changes reconcile to server-confirmed state, preserve keyboard focus during saves, and surface conflicts such as the last-admin invariant.
  • Cluster-aware websocket events invalidate the canonical space and roster state across nodes without maintaining a second hook-local permission cache.

Testing

  • Go tests cover model mappings, pooled-scheme resolution, access gates, membership invariants, store locking, handlers, and websocket events. The open-to-private regression cases pin pre-commit deletion, cleanup failure leaving the space open, not-found cleanup, stale-baseline rejection before deletion, and removal-event delivery.
  • Jest tests cover the permissions client, Redux state, hooks, and settings UI, including save races, failure reconciliation, the licensed checkbox matrix, and the unlicensed preset selector.
  • Playwright runs against a real Mattermost server with the plugin installed. The permission suite covers defaults and individual grants, open/private spaces, pruning an auto-joined author while retaining an invited member, page actions, membership, guests, space/team administrators, and all four System Console space permissions. An unlicensed scenario verifies that all three included presets remain selectable without exposing arbitrary combinations.
  • CI pins the paired core image through build/core-commit.txt and verifies that the image supports the required core roles before running permission tests.

Dependency

Requires mattermost/mattermost#37685. server/public and the E2E core image remain pinned to the paired core branch until that change is released.

Consider NOT VALID for the CHECK, and note this statement is not retry-safe.

Two things about line 5:

  • ADD CONSTRAINT ... CHECK takes ACCESS EXCLUSIVE and scans the table to validate. Every row was just written by the DEFAULT 'private' on line 1, so the scan can only pass — adding it NOT VALID (enforced for new writes, no scan) avoids blocking writes on a large DOCS_Space.
  • Unlike line 1, Postgres has no ADD CONSTRAINT IF NOT EXISTS, so a re-run after a partially applied migration fails with duplicate_object and leaves the version dirty for an operator to clear.

BuildSpaceWithAccess dereferences space.Id immediately, while CreateSpace, SetSpaceDefaultCapabilities, UpdateSpace, ListSpaceMembers, and AddSpaceMember all open with an explicit nil check returning 400. Current callers pass a non-nil record, so this is convention/future-proofing rather than a live panic.

Prefer building the OR branch in Go over binding a bare bool parameter as a predicate.

sq.Expr("?", callerHasOpenFallthrough) emits a placeholder in boolean position and leans on Postgres resolving the untyped parameter to boolean. It works with the current driver (the store tests cover both values), but dropping the branch when the caller lacks the fall-through is clearer and lets the planner skip the ViewAccess predicate entirely.

♻️ Suggested change
-	memberExists := sq.Expr("EXISTS (SELECT 1 FROM ChannelMembers cm WHERE cm.ChannelId = sp.ChannelId AND cm.UserId = ?)", userID)

Confirm the WS publish inside the membership lock is intentional.

publishToChannels runs while WithSpaceMembershipLock still holds its dedicated connection; a slow plugin-API RPC extends lock hold time and can push concurrent membership mutations into ReasonLockTimeout 409s. Moving the publish after the lock closure (using the captured joined/member.UserId) would keep the critical section to DB + membership work only.

@coderabbitai - On two of the nitpicks from the review body (no inline threads on those, so answering here):

server/e2e/helpers_test.go:79 (revive context-as-argument): revive is configured with an explicit rules list (only exported + unused-parameter, see .golangci.yml), so context-as-argument is not enabled. Note also that server/e2e sits behind the e2e build tag and we do not set run.build-tags, so ./... never loads the package. Verified both ways: golangci-lint run --build-tags e2e ./server/e2e/... -> 0 issues.

server/model/space_capabilities_test.go:112-121 (slices.Backward): modernize is enabled and does not flag this loop, since it appends each element twice per iteration (not the shape it rewrites). golangci-lint run ./server/model/... -> 0 issues, on both v2.9.0 (bin/) and v2.11.4.

Refresh mounted permission settings after membership events.

These handlers refresh Redux state only. useSpacePermissions stores the roster, defaults, and authority flags in local state, and its load effect depends only on space.id.

If another user is added, removed, or updated while the permission settings modal stays open, this code does not reload that hook. The displayed roster and authority state remain stale.

Add an invalidation path that causes mounted useSpacePermissions instances to reload after these events, or source this state from the refreshed Redux slice.

Consider a plain string instead of new RegExp(name).

getByRole already matches an accessible name by substring when it receives a string, so the constructed regular expression adds no matching capability here. Passing name directly reads more plainly and removes the two ast-grep regexp-from-variable warnings. name is a closed union of two literals, so there is no actual ReDoS exposure.

Move the orphan doc comment onto receivedSpaceAccess.

Two consecutive doc blocks precede ensureSpaceMembership. The first block (Lines 335-340) describes receivedSpaceAccess, but it is attached to ensureSpaceMembership. receivedSpaceAccess at Line 370 then has no documentation. Editors and doc tooling will show the wrong text for both functions.

 /**
  * Joins the caller to a space when the server has said they may join it, before a write of theirs

In `@e2e-tests/playwright/README.md`:
- Line 74: Update the table row describing waitForPhase2Migration() to add the
missing trailing pipe, matching the formatting of the other rows and satisfying
MD055.

In `@e2e-tests/playwright/tests/docs/space_permissions.spec.ts`:
- Around line 366-370: Annotate the four documented expected-failure tests in
space_permissions.spec.ts with test.fail(), including the test beginning “a
member is not offered page actions the space default withholds” and the tests at
the other specified locations. Keep their existing test bodies and descriptions
unchanged.

In `@e2e-tests/playwright/tests/helpers/bootstrap.ts`:
- Around line 59-67: Wrap the post-start readiness and permission checks around
assertReadyForSpecs, restoreBaselineTeamPermissions, and
assertSpacePermissionsSupported in cleanup handling so any thrown error stops
the server container and its associated Postgres container and network before
propagating the failure. Preserve the existing successful path and returned
teardown behavior from globalSetup.

In `@server/app/service.go`:
- Around line 127-130: Update the comment for membershipLockAppError to identify
lock-acquisition timeouts as *store.ErrConflict errors with ReasonLockTimeout,
and remove the incorrect ErrLockTimeout reference while preserving the existing
explanation of error mapping.

In `@server/store/space_store.go`:
- Around line 104-107: Update the visibility expression in the space-listing
logic so the ChannelMembers EXISTS branch also requires a corresponding active
TeamMembers row with DeleteAt = 0 for the user; preserve the separate
callerHasOpenFallthrough behavior and its open ViewAccess condition.

In `@webapp/src/components/create_space_modal/create_space_modal.tsx`:
- Line 99: Update the name-field SpaceIcon binding in the create-space modal to
derive its view_access value from state.values.view_access via form.Subscribe,
so the icon reflects the selected access level instead of always using private.

In `@webapp/src/hooks/space_permissions.test.tsx`:
- Around line 203-220: Remove the stale first explanatory comment paragraph
above the test “drops the previously resolved policy when a later space fails to
load.” Keep the following paragraph, which correctly documents that defaults are
cleared while viewAccess comes from the current space record.

In `@webapp/src/hooks/spaces.ts`:
- Around line 140-143: Update the cleanup function in the space-fetching effect
to clear resolvedFor.current only when it still matches that effect’s spaceId,
while retaining request cancellation and timer cleanup. Add a regression test
covering navigation from space-1 to undefined and back to space-1 before the
original promise settles, ensuring a new request is issued and permissions
resolve.

@catalintomai I started a full review of #10.

The two addressed review-body nitpicks are not unresolved review threads. I did not resolve the remaining nine threads because they concern separate findings and have no confirmation of a matching fix.

Timestamp: 2026-08-23T20:36:01.017Z
Learning: In the Mattermost Docs webapp, `getCanCreatePage` in `webapp/src/store/permissions.ts` deliberately returns true when `space.permissions` is undefined. This keeps page-creation controls available when a team listing lacks resolved permissions; the server enforces creation authority. `getCanManageSpaceMembers` intentionally differs and fails closed because it gates administrative UI. `webapp/src/components/space_view/page_header.tsx` and `webapp/src/components/space_view/page_tree/page_tree_panel.tsx` must use the same `useCanCreatePage` contract for the Add page action.

Timestamp: 2026-08-23T20:35:31.139Z
Learning: In `server/model/space_permissions.go`, `ValidateDefaultPermissions` accepts only the five atomic page permissions in `grantableDefaultPermissions`; it excludes `admin_space`. `manage_space` is not a space default or member grant. Therefore, in `webapp/src/hooks/space_permissions.ts`, `setDefaults` cannot change `canAdminister` or `canManageMembers`; only a self-targeted `setMemberGrants` update can require `reloadTiers()` because member grants may include `admin_space`.

File: e2e/specs/functional/space_permissions_modal.spec.ts:70-91
Timestamp: 2026-08-08T07:53:40.170Z
Learning: In this branch, `webapp/src/store/actions.ts` implements `fetchSpaces()` with fixture data from `docsDataSource.listSpaces()`, and `webapp/src/data/index.ts` exports `mockDataSource` as `docsDataSource`. The Docs sidebar is therefore not API-backed. The Playwright spec `e2e/specs/functional/space_permissions_modal.spec.ts` can test only permissions-modal reachability; an API-created space does not appear in the fixture-backed sidebar. The full permissions round-trip remains covered by `server/e2e/scenarios_test.go` until the webapp data source uses the plugin API.

File: server/api_space.go:132-141
Timestamp: 2026-08-08T07:42:08.825Z
Learning: In `server/app/space.go`, `Service.UpdateSpace` calls `RequireSpaceAdminOrSysadmin` for a real `ViewAccess` change. The gate permits only sysadmins or active backing-channel members with `PermissionAdminSpace`; it does not permit team `manage_space` open-space fall-through. Therefore, `server/api_space.go` can carry `BuildSpaceWithAccess` capability data from before a permitted `ViewAccess` update without making it stale.

File: webapp/src/components/space_settings_modal/space_settings_modal.tsx:196-202
Timestamp: 2026-08-08T07:41:53.193Z
Learning: In the Mattermost Docs plugin, space default capabilities are stored in the backing scheme role permissions rather than in the `Space` row. `Space.UpdateAt` does not advance when `SetSpaceDefaultCapabilities` updates defaults, so optimistic locking for default-capability writes requires separate server and client versioning.

File: server/api_space.go:122-127
Timestamp: 2026-08-04T14:19:25.214Z
Learning: In the Go Space API update flow, `server/app/space.go` Lines 519-534 define the post-commit response convention: degrade only when a post-commit re-read fails; return the error when `BuildSpaceWithAccess` fails. `model.SpaceWithAccess` must contain truthful effective capabilities, so handlers must not synthesize a degraded wrapper when capability projection fails.

Reuse adminToken inside assertPluginActive.

Lines 99-111 repeat the sign-in request and the failure message already present at Lines 67-79. Two copies of the same message can drift. Call adminToken from assertPluginActive instead.

♻️ Proposed refactor
 export async function assertPluginActive(baseURL: string, username: string, password: string) {
-    const login = await fetch(`${baseURL}/api/v4/users/login`, {
-        method: 'POST',
-        headers: {'Content-Type': 'application/json'},
-        body: JSON.stringify({login_id: username, password}),
-        signal: AbortSignal.timeout(requestTimeoutMs),
-    });
-
-    const token = login.headers.get('token');
-    if (!login.ok || !token) {
-        throw new Error(
-            `Unable to sign in to ${baseURL} as "${username}" (${login.status}). Set MM_ADMIN_USERNAME and MM_ADMIN_PASSWORD for that server.`,
-        );
-    }
+    const token = await adminToken(baseURL, username, password);
 
     const response = await fetch(`${baseURL}/api/v4/plugins/webapp`, {

adminToken must then be declared above assertPluginActive, or kept as a function declaration so hoisting applies.

and other error handling, and only build the role mapping when the returned role
names are populated.

In `@webapp/package.json`:
- Around line 100-102: Update the Jest collectCoverageFrom patterns in package
configuration to exclude source files matching *.test.* and *.spec.* using
negated globs, while preserving the existing TypeScript source and
declaration-file exclusions.

In `@webapp/src/store/entities.ts`:
- Around line 127-130: Update the space merge in the reducer handling
RECEIVED_SPACES to preserve can_join using the same nullish fallback pattern as
permissions and default_permissions, retaining the previously known value when
the listing omits it. Add a reducer test covering a detailed space followed by a
bare listing and verify can_join remains available.

---

Nitpick comments:
In `@e2e-tests/playwright/tests/helpers/preflight.ts`:
- Around line 96-114: Update assertPluginActive to call the existing adminToken
helper instead of duplicating the login request and error handling; ensure
adminToken is declared before assertPluginActive or remains a hoisted function
declaration.

In `@webapp/src/components/space_settings_modal/space_settings_modal.tsx`:
- Around line 62-77: Update the archive TabPanel rendering in the space settings
modal to condition it on canArchive, so ArchiveTab is not mounted when the
archive tab is unavailable, including when initialTab is 'archive' but
permission is denied.

@catalintomai I checked all 10 unresolved CodeRabbit threads against PR head b307143a14238052951ee77e06c7765de129db44.

I resolved three threads:

  1. e2e-tests/playwright/README-VENDORED.md: the file no longer exists.
  2. webapp/src/hooks/space_permissions.test.tsx: the comment is corrected at Lines 203-206.
  3. space_permissions.spec.ts expected failures: I withdrew this finding. The current suite does not document intentional failures, so test.fail() is not justified.

Seven threads are still valid and are not fixed in the current branch:

  1. e2e-tests/playwright/README.md Line 75 lacks the trailing table pipe.
  2. e2e-tests/playwright/tests/docs/space_permissions.spec.ts Lines 947 and 978 use the test-scoped server fixture in beforeAll and afterAll.
  3. e2e-tests/playwright/tests/docs/system_console_space_permissions.spec.ts sets rollback flags after scheme.save() at Lines 189-190, 249-250, 302-303, and 341-342.
  4. server/app/permissions_test.go Line 314 names TestAutoJoin_DefaultDoesNotGrant, but the declared test is TestJoinOpenSpace_ReadOnlyDefaultsRefused.
  5. server/app/scheme.go Lines 85-97 accepts empty role names from GetRolesForChannel.
  6. webapp/package.json Lines 99-102 includes *.test.* and *.spec.* files in collectCoverageFrom.
  7. webapp/src/store/entities.ts Lines 127-131 preserves permissions and default_permissions, but it still drops previously resolved can_join. This can remove authoring affordances for an open-space non-member after a bare listing refresh.

Repo: mattermost/mattermost-plugin-docs PR: 10
File: webapp/src/components/space_view/page_tree/page_tree_panel.tsx:338-351
Timestamp: 2026-08-23T20:36:01.017Z
Learning: In the Mattermost Docs webapp, `getCanCreatePage` in `webapp/src/store/permissions.ts` deliberately returns true when `space.permissions` is undefined. This keeps page-creation controls available when a team listing lacks resolved permissions; the server enforces creation authority. `getCanManageSpaceMembers` intentionally differs and fails closed because it gates administrative UI. `webapp/src/components/space_view/page_header.tsx` and `webapp/src/components/space_view/page_tree/page_tree_panel.tsx` must use the same `useCanCreatePage` contract for the Add page action.

File: server/app/service.go:127-137
Timestamp: 2026-08-23T20:35:48.871Z
Learning: In the Mattermost Docs plugin, `server/store/space_store.go` represents a `WithSpaceMembershipLock` acquisition timeout as `*store.ErrConflict` with `Reason: store.ReasonLockTimeout`. `server/store/store.go` provides `store.IsErrLockTimeout(err)` as a predicate over that `*store.ErrConflict`; there is no `ErrLockTimeout` type.

Repo: mattermost/mattermost-plugin-docs PR: 10
File: webapp/src/hooks/space_permissions.ts:198-220
Timestamp: 2026-08-23T20:35:31.139Z
Learning: In `server/model/space_permissions.go`, `ValidateDefaultPermissions` accepts only the five atomic page permissions in `grantableDefaultPermissions`; it excludes `admin_space`. `manage_space` is not a space default or member grant. Therefore, in `webapp/src/hooks/space_permissions.ts`, `setDefaults` cannot change `canAdminister` or `canManageMembers`; only a self-targeted `setMemberGrants` update can require `reloadTiers()` because member grants may include `admin_space`.

File: webapp/src/client/rest.ts:70-73
Timestamp: 2026-08-23T20:35:21.022Z
Learning: In `webapp/src/client/rest.ts`, `request<T>` handles a JSON `null` error payload through its existing `try`/`catch` fallback. Accessing `data.error` can throw for `null`, but the `catch` absorbs that exception and the subsequent `throw new RestError(...)` preserves the HTTP status and status-based fallback message.

File: server/app/ws_events.go:79-91
Timestamp: 2026-08-18T12:16:32.023Z
Learning: In `server/app/ws_events.go`, `Service.publishToChannels` must resolve `Store.InactiveTeamChannelMembers` with a live database read before each channel-scoped WebSocket broadcast. Do not introduce a per-process omit-list cache unless it has complete and synchronous cluster-wide invalidation for all team and channel membership changes. A stale cache entry can leak space activity to users whose access was revoked.

Timestamp: 2026-08-08T07:53:40.170Z
Learning: In this branch, `webapp/src/store/actions.ts` implements `fetchSpaces()` with fixture data from `docsDataSource.listSpaces()`, and `webapp/src/data/index.ts` exports `mockDataSource` as `docsDataSource`. The Docs sidebar is therefore not API-backed. The Playwright spec `e2e/specs/functional/space_permissions_modal.spec.ts` can test only permissions-modal reachability; an API-created space does not appear in the fixture-backed sidebar. The full permissions round-trip remains covered by `server/e2e/scenarios_test.go` until the webapp data source uses the plugin API.

Timestamp: 2026-08-08T07:42:08.825Z
Learning: In `server/app/space.go`, `Service.UpdateSpace` calls `RequireSpaceAdminOrSysadmin` for a real `ViewAccess` change. The gate permits only sysadmins or active backing-channel members with `PermissionAdminSpace`; it does not permit team `manage_space` open-space fall-through. Therefore, `server/api_space.go` can carry `BuildSpaceWithAccess` capability data from before a permitted `ViewAccess` update without making it stale.

Timestamp: 2026-08-08T07:41:53.193Z
Learning: In the Mattermost Docs plugin, space default capabilities are stored in the backing scheme role permissions rather than in the `Space` row. `Space.UpdateAt` does not advance when `SetSpaceDefaultCapabilities` updates defaults, so optimistic locking for default-capability writes requires separate server and client versioning.

Learning: In the mattermost-plugin-docs repository, there is no Stylelint configuration or dependency. The `npm run lint` command runs ESLint only, so Stylelint findings do not apply.

Learning: In this Go repository, `server/e2e/container_test.go` is guarded by `//go:build e2e` and is the only consumer of `github.com/mattermost/testcontainers-mattermost-go v0.1.0`. That wrapper pins `github.com/testcontainers/testcontainers-go v0.35.0`, which resolves `github.com/docker/docker v27.1.1+incompatible`. Upgrading the wrapper’s Testcontainers dependency independently is incompatible; defer the Docker client upgrade until a compatible `testcontainers-mattermost-go` release is available.

Timestamp: 2026-07-27T17:43:21.997Z
Learning: In the Go space RBAC implementation, `server/app/space.go` `resolveSpaceScheme` reuses only seeded preset schemes; every non-preset default-capability set creates a fresh, immutable custom scheme. `Service.SetSpaceDefaultCapabilities` serializes a space’s backing-channel scheme repoint and superseded-custom-scheme retirement with `Store.WithSpaceMembershipLock(space.Id)`. Do not flag `Store.DeleteSpaceCustomSchemeIfUnreferenced` for a concurrent custom-scheme reattachment without evidence of a path that reuses custom scheme IDs.

File: server/store/page_move.go:250-255
Timestamp: 2026-07-27T17:41:52.366Z
Learning: In the Go page store, page hierarchy mutations serialize through the owning `DOCS_Space` row lock: `MovePageToSpace` locks both source and target spaces before the subtree traversal; same-space moves, subtree creation, restore, and delete-time child promotion acquire the relevant space lock before changing live page parentage. Consequently, `MovePageToSpace` may safely use its unlocked recursive subtree read within that transaction; separate descendant row locks are unnecessary for preventing concurrent grafts.

@catalintomai I rechecked the current PR head fa54876b2eb76535a83077730571157b282d3380.

I resolved all seven threads.

  • The Playwright hooks now use readState() and do not request the test-scoped server fixture.
  • The system-scheme tests register rollback before scheme.save().
  • The Go test comment names TestJoinOpenSpace_ReadOnlyDefaultsRefused.
  • collectCoverageFrom excludes *.test.* and *.spec.*.
  • The reducer preserves can_join, with a detail-then-list regression test.
  • The scheme code now uses Scheme.GetForChannel and rejects incomplete aggregate responses.
  • The Markdown table finding does not apply. The table consistently uses leading-only pipes.

File: webapp/src/components/space_view/page_tree/page_tree_panel.tsx:338-351
Timestamp: 2026-08-23T20:36:01.017Z
Learning: In the Mattermost Docs webapp, `getCanCreatePage` in `webapp/src/store/permissions.ts` deliberately returns true when `space.permissions` is undefined. This keeps page-creation controls available when a team listing lacks resolved permissions; the server enforces creation authority. `getCanManageSpaceMembers` intentionally differs and fails closed because it gates administrative UI. `webapp/src/components/space_view/page_header.tsx` and `webapp/src/components/space_view/page_tree/page_tree_panel.tsx` must use the same `useCanCreatePage` contract for the Add page action.

Timestamp: 2026-08-23T20:35:48.871Z
Learning: In the Mattermost Docs plugin, `server/store/space_store.go` represents a `WithSpaceMembershipLock` acquisition timeout as `*store.ErrConflict` with `Reason: store.ReasonLockTimeout`. `server/store/store.go` provides `store.IsErrLockTimeout(err)` as a predicate over that `*store.ErrConflict`; there is no `ErrLockTimeout` type.

File: webapp/src/hooks/space_permissions.ts:198-220
Timestamp: 2026-08-23T20:35:31.139Z
Learning: In `server/model/space_permissions.go`, `ValidateDefaultPermissions` accepts only the five atomic page permissions in `grantableDefaultPermissions`; it excludes `admin_space`. `manage_space` is not a space default or member grant. Therefore, in `webapp/src/hooks/space_permissions.ts`, `setDefaults` cannot change `canAdminister` or `canManageMembers`; only a self-targeted `setMemberGrants` update can require `reloadTiers()` because member grants may include `admin_space`.

File: webapp/src/client/rest.ts:70-73
Timestamp: 2026-08-23T20:35:21.022Z
Learning: In `webapp/src/client/rest.ts`, `request<T>` handles a JSON `null` error payload through its existing `try`/`catch` fallback. Accessing `data.error` can throw for `null`, but the `catch` absorbs that exception and the subsequent `throw new RestError(...)` preserves the HTTP status and status-based fallback message.

Timestamp: 2026-08-18T12:16:32.023Z
Learning: In `server/app/ws_events.go`, `Service.publishToChannels` must resolve `Store.InactiveTeamChannelMembers` with a live database read before each channel-scoped WebSocket broadcast. Do not introduce a per-process omit-list cache unless it has complete and synchronous cluster-wide invalidation for all team and channel membership changes. A stale cache entry can leak space activity to users whose access was revoked.
