Add read-only support for the Nextcloud Mail app, plus semantic indexing
of mail messages. The MCP server never speaks IMAP/POP3 itself: it calls
the Mail app's CSRF-free OCS API (/ocs/v2.php/apps/mail/api/...) with the
existing Basic-Auth app-password flow and an OCS-APIRequest header, and the
Mail app handles IMAP server-side.
- client/mail.py: MailClient (accounts, mailboxes, messages, message,
attachment), OCS-envelope aware.
- models/mail.py: Pydantic models with the API's camelCase aliases.
- server/mail.py: 5 read-only MCP tools (mail.read scope), registered in
AVAILABLE_APPS.
- Vector pipeline: new "mail_message" doc_type wired into scanner
(scan_mail_messages, newest-N per mailbox), processor (body -> markdown
embedding), per-id verifier, and context expansion.
- Tests: client API, model round-trips, verifier behavior; consent-backstop
test now derives its allowed set from INDEXED_DOC_TYPES.
- README + semantic-search docstrings updated.
Requires Mail 5.x / Nextcloud 32+ and a mail account configured in the
Mail app. Follow-up: astrolabe must advertise "mail_message" in its
enabled_doc_types capability for search under admin doc_type restriction.

Many identity providers (AWS Cognito, Okta, Azure AD) reject or mishandle
colons in OAuth scope names. This migrates all custom scopes from
`resource:action` to `resource.action` format (e.g., `notes:read` →
`notes.read`), which is universally accepted and aligns with industry
conventions (Microsoft, Google).
Includes Alembic migration 004 for stored scope strings and ADR-024
documenting the rationale and RFC references.

Implement MCP tools for the Collectives wiki/documentation app, enabling
agentic workflows for team knowledge base management.
16 tools covering collectives, pages, tags, search, and trash:
- Read: list collectives, list/get pages (with WebDAV content), search,
list tags, list trashed pages
- Write: create/update collective, create/move/trash/restore pages,
set emoji, create/assign/remove tags
Includes Docker hook for app installation, OCS API client with envelope
unwrapping, Pydantic models, unit tests (16), and integration tests (10).

- Add 429 retry with exponential backoff to register_client() (fixes CI
oauth matrix failures from parallel DCR requests)
- Make client_id, redirect_uri, and PKCE mandatory at token endpoint
- Add null-checks for discovery_url and OAuth credentials in proxy flows
- Add OIDC discovery document caching with 5-min TTL
- Add per-IP rate limiting on /oauth/register DCR proxy
- Discover DCR endpoint from OIDC discovery instead of hardcoding
- Extract extract_user_id_from_token to auth/token_utils.py (breaks
circular imports between server/ and auth/ layers)
- Add TTL scope cache in scope_authorization.py (avoids DB hit per tool)
- Add defense-in-depth scope validation in storage layer
- Broaden elicitation exception handling with graceful fallback
- Add idempotentHint to nc_auth_check_status, return "pending" status
after accepted elicitation, add polling interval to description
- Change ALL_SUPPORTED_SCOPES from tuple to frozenset for O(1) lookups
- Replace Optional[str] with str | None throughout config.py
- Use default_factory for ProxyCodeEntry/ASProxySession dataclasses
- Add proxy code/session cleanup to background loop
- Fix OIDC verification CI step to only run for oauth/login-flow modes
- Add unit tests for access.py REST endpoints (10 tests)

- Consolidate MCP session + login flow cleanup into _mcp_session_with_login_flow() helper,
replacing 4 duplicated AsyncExitStack sites in app.py
- Fix get_shared_storage() race condition by using module-level anyio.Lock() init
(reverts regression from ba59763)
- Collapse cosmetic if/else branching in scope_authorization.py
- Consolidate dual password storage paths into single store_app_password_with_scopes() call
- Mark unused request param as _ in list_supported_scopes
- Make ALL_SUPPORTED_SCOPES an immutable tuple; use list() instead of .copy()
- Add hasattr(ctx, "elicit") guard in elicitation.py, narrow except to NotImplementedError
- Add YAML comment explaining --oauth flag for mcp-login-flow service

- Fix anyio.Lock() created at module import time; use lazy init in
get_shared_storage() to avoid instantiation before event loop exists
- Stop get_login_flow_session from silently swallowing DB exceptions;
re-raise and handle in caller with proper error response
- Update ProvisionAccessResponse and UpdateScopesResponse status field
docs to include all actual values (declined, cancelled, unchanged)
- Narrow except clause in present_login_url to (AttributeError,
NotImplementedError) instead of bare Exception
- Add KeyError handling in LoginFlowV2Client.initiate() and poll() for
clear errors on malformed Nextcloud responses
- Simplify redundant env-var bypass branches in scope_authorization.py
- Extract _maybe_login_flow_cleanup() context manager to replace 4
inline cleanup loop registrations in app.py; move sleep to end of
loop body so cleanup runs once at startup
- Replace fragile string replacement in _rewrite_login_flow_url with
proper urllib.parse URL handling
