Commit 4 renamed `[oauth_single_audience]` → `[login_flow]` via a global
sed pass, but ADR-025's example settings.toml already had a `[login_flow]`
section just above the `[keycloak]` block. The rename produced two
back-to-back `[login_flow]` headers with identical contents — TOML parsers
either reject the file or silently override, and a reader copying the
example would land on either outcome.
Dropped the now-duplicate second `[login_flow]` section (the renamed one).
The earlier `[login_flow]` section retains the same content + a comment
explaining the ADR-022 derivation, so no information is lost.

Four small follow-ups from the reviewer's latest pass:
- tests/unit/test_stdio.py:18: the single_user_env fixture used
monkeypatch.delenv("ENABLE_MULTI_USER_BASIC_AUTH", ...). That env var
is no longer read after the ADR-022 follow-up; switched to delenv of
MCP_DEPLOYMENT_MODE which is the canonical mode-selection input today.
Comment updated to match.
- config_validators.py: when detect_auth_mode rejects an invalid
MCP_DEPLOYMENT_MODE, surface a one-line ADR-022 migration hint if the
rejected value is exactly "oauth_single_audience" (the most common
upgrade pain — users carrying that value over from ADR-021 .env files).
Other invalid values get the regular "Valid values: …" message
unchanged.
- config.py + config_validators.py: added cross-reference comments on
both mode-resolution sites (Settings.__post_init__ and
detect_auth_mode) noting that they each compute the canonical mode
independently and must be kept in sync when a new mode is added.
Surfaces the parallel-duplication intentionally so the next maintainer
doesn't have to discover it.
- docs/ADR-021-configuration-consolidation.md:92: appended a trailing
comment to the historical "valid values" example, marking
oauth_single_audience and oauth_token_exchange as removed in ADR-022.
ADR-021 stays as the historical record; the trailer points future
readers at the current state.
No functional changes; 1009 unit tests still pass.

Five small findings from the reviewer's third round, plus a SonarCloud
quality-gate failure on a test fixture.
- docs/troubleshooting.md, docs/configuration.md: six pre-PR references
to a non-existent `login_flow_v2` mode value (the actual enum value is
`login_flow`). They predated this PR but became actively misleading
once `detect_auth_mode` started raising ValueError for anything not in
the mode_map. Replaced with `login_flow` via sed.
- docs/configuration-migration-v2.md: removed a duplicate
`MCP_DEPLOYMENT_MODE=multi_user_basic` line in the troubleshooting
section (around line 447) — same shape as the round-2 duplicate
caught earlier in the migration-steps section. Also dropped the
`oauth_token_exchange` row from the mode-value table around line 364
(that enum value was removed in 57303135 and would now raise
ValueError from detect_auth_mode).
- nextcloud_mcp_server/config.py: field comments for
`enable_multi_user_basic_auth` and `enable_login_flow` said
"Auto-set by detect_auth_mode()" but the derivation moved into
`Settings.__post_init__` in the previous commit. Updated both.
- tests/unit/test_config_validators.py: SonarCloud's python:S2068
flagged `nextcloud_password="hunter2"` in the
`test_login_flow_mode_auto_derives_enable_login_flow_flag` fixture I
added in commit 5 as a potentially hard-coded credential. Other
fixtures in the same file use the literal `"password"` and aren't
flagged (they predate the PR and SonarCloud only checks new-code).
Switched to `"password"` to match the existing convention.
No functional changes; all 1009 unit tests still pass.

The integration jobs for `mcp-multi-user-basic` and `mcp-login-flow`
were failing with HTTP 500s. Root cause: `get_settings()` builds a
fresh Settings on every call (not cached). Commits 3 and 4 set the
derived `enable_login_flow` / `enable_multi_user_basic_auth` flags as
a side effect of `detect_auth_mode`. detect_auth_mode runs once at
startup, against the Settings instance owned by `validate_configuration`.
Every per-request call site that does `settings = get_settings()` got
a fresh Settings with both flags at their default `False` (since the
env-var aliases were dropped), causing the multi-user dispatcher in
`context.py` to take the wrong branch and crash.
Fix: move the derivation into `Settings.__post_init__`. Every Settings
instance now carries correct flags from the moment it's constructed —
no caching needed, no mutation-after-construction race. detect_auth_mode
becomes a pure reader of the already-derived state.
The legacy env-var deprecation check moves with it. It also picks up
the reviewer's truthy-string fix: previously `os.getenv(legacy)` fired
for the literal string "false" (a non-empty Python string is truthy),
which would have errored on any user with a leftover
`ENABLE_LOGIN_FLOW=false` in their `.env`. The check now only fires
when the value lowercases to one of {"1", "true", "yes", "on"}.
- nextcloud_mcp_server/config.py: extend Settings.__post_init__ with
the legacy-deprecation block and the derived-flag derivation
(resolve mode from deployment_mode + username/password, set flags).
- nextcloud_mcp_server/config_validators.py: drop the
`_sync_derived_flags` helper (superseded by __post_init__). Drop the
legacy-env-var deprecation block (moved). `detect_auth_mode` is now
pure — no mutation. Drop the now-unused `import os`.
- tests/unit/test_config_validators.py: legacy-env-var tests now
expect `ValueError` at `Settings(...)` construction (via `get_settings()`),
not at `detect_auth_mode` call. Added two new tests:
* `test_legacy_env_var_check_ignores_falsy_strings` — pins the
truthy-string fix (reviewer round 2 finding).
* `test_derived_flags_stable_across_get_settings_calls` — regression
test pinning the integration-test fix (two consecutive
`get_settings()` calls return Settings instances with the same
derived flags).
Also reworked `test_login_flow_mode_auto_derives_enable_login_flow_flag`
to assert at-construction derivation (not the old mutation pattern).
- docs/configuration-migration-v2.md: dropped the duplicate
`MCP_DEPLOYMENT_MODE=multi_user_basic` line (review round 2 nit — a
sed artifact from commit 4).
- docs/ADR-021-configuration-consolidation.md: sed-replaced the in-body
`MCP_DEPLOYMENT_MODE=oauth_single_audience` examples with `login_flow`
(review round 2 nit — only the status header was updated in commit 4).
- tests/conftest.py: docstring comment for the multi-user-basic fixture
switched from `ENABLE_MULTI_USER_BASIC_AUTH=true` to
`MCP_DEPLOYMENT_MODE=multi_user_basic` (review round 2 nit).

Same pattern as the ENABLE_LOGIN_FLOW removal in the previous commit:
the deployment mode (MCP_DEPLOYMENT_MODE) is the single source of truth
for selecting an auth flow. The ENABLE_MULTI_USER_BASIC_AUTH env-var
alias is redundant with `MCP_DEPLOYMENT_MODE=multi_user_basic`.
Unlike the ENABLE_LOGIN_FLOW removal — where silent removal was safe
because Login Flow v2 is the auto-detection default — silent removal
here would be a surprise: a user with only ENABLE_MULTI_USER_BASIC_AUTH=true
in their .env would auto-detect into LOGIN_FLOW after upgrade (wrong
runtime mode). Mitigation: detect_auth_mode now reads os.environ
directly for both legacy aliases and raises ValueError with a one-line
migration message if either is set. Applied retroactively to
ENABLE_LOGIN_FLOW as well — loud is better than silent.
- nextcloud_mcp_server/config.py:
- Drop the dynaconf env-var alias entry for ENABLE_MULTI_USER_BASIC_AUTH.
- Update the `enable_multi_user_basic_auth` field docstring to mark it
as derived / not user-settable.
- `_is_multi_user_mode()` (early-config helper, runs before Settings
is built) switched to checking MCP_DEPLOYMENT_MODE directly. Now
consistent with the canonical detection in detect_auth_mode.
- nextcloud_mcp_server/config_validators.py:
- Drop the auto-detection branch (`if settings.enable_multi_user_basic_auth`).
Selection of MULTI_USER_BASIC is now exclusively via the explicit
MCP_DEPLOYMENT_MODE branch.
- Add `enable_multi_user_basic_auth` to `_sync_derived_flags` alongside
`enable_login_flow` — both flags are now derived from the resolved mode.
- Drop `enable_multi_user_basic_auth` from
`MODE_REQUIREMENTS[MULTI_USER_BASIC].required` and from the
`forbidden` lists of SINGLE_USER_BASIC and LOGIN_FLOW (no longer
user input → no meaningful forbidden check).
- Add loud-deprecation `ValueError` block at the top of detect_auth_mode
that errors with a clear migration message when ENABLE_MULTI_USER_BASIC_AUTH
or ENABLE_LOGIN_FLOW is found in os.environ.
- tests/unit/test_config_validators.py:
- Switch ~10 fixtures from `enable_multi_user_basic_auth=True` to
`deployment_mode="multi_user_basic"` (mirrors `enable_login_flow`
treatment from the previous commit).
- Switch two `patch.dict(os.environ, {"ENABLE_MULTI_USER_BASIC_AUTH": "true"})`
blocks to use MCP_DEPLOYMENT_MODE.
- Rename `test_forbidden_multi_user_basic_auth` to
`test_forbidden_multi_user_basic_when_credentials_present` — the
scenario is now an explicit-mode + credentials conflict, not an
env-var-flag conflict.
- Add `test_legacy_enable_multi_user_basic_auth_env_var_errors` and
`test_legacy_enable_login_flow_env_var_errors` to exercise the new
loud-deprecation ValueError path.
- docker-compose.yml: mcp-multi-user-basic profile switched to
`MCP_DEPLOYMENT_MODE=multi_user_basic`.
- env.sample: replaced `#ENABLE_MULTI_USER_BASIC_AUTH=true` example with
`#MCP_DEPLOYMENT_MODE=multi_user_basic`.
- docs/authentication.md, configuration.md, troubleshooting.md,
auth-flows.md, webhook-management-guide.md,
configuration-migration-v2.md, ADR-025: replaced env-var examples
with the canonical MCP_DEPLOYMENT_MODE form.
- docs/ADR-020: marked partly superseded by ADR-022.
- CLAUDE.md: Multi-User BasicAuth section updated to set
MCP_DEPLOYMENT_MODE.
- nextcloud_mcp_server/vector/oauth_sync.py: module docstring updated.
BREAKING CHANGE: ENABLE_MULTI_USER_BASIC_AUTH is no longer read from
the environment, and setting it now raises a startup ValueError with
a migration message. Replace `ENABLE_MULTI_USER_BASIC_AUTH=true` with
`MCP_DEPLOYMENT_MODE=multi_user_basic`. The same loud-deprecation
check is also applied to the recently-removed ENABLE_LOGIN_FLOW —
replace with `MCP_DEPLOYMENT_MODE=login_flow` (or drop both;
`login_flow` is the auto-detect default when no other auth env vars
are set).

Once OAUTH_SINGLE_AUDIENCE was renamed to LOGIN_FLOW and the validation
gate ensured the only meaningful configuration was
`MCP_DEPLOYMENT_MODE=login_flow + ENABLE_LOGIN_FLOW=true`, the two
controls became redundant. Setting the mode is sufficient; the
ENABLE_LOGIN_FLOW env var doesn't add information.
This commit makes the deployment mode the single source of truth for
the Login Flow v2 toggle:
- `nextcloud_mcp_server/config.py`: drop the `ENABLE_LOGIN_FLOW`
dynaconf env-var alias. The `enable_login_flow` field stays as an
internal attribute so the 6 runtime call sites (app.py x4,
context.py, auth/scope_authorization.py) keep working unchanged.
Updated field docstring to flag it as derived.
- `nextcloud_mcp_server/config_validators.py`:
- Drop `enable_login_flow` from `MODE_REQUIREMENTS[LOGIN_FLOW].required`.
- Drop the validation gate that required ENABLE_LOGIN_FLOW=true for
LOGIN_FLOW mode (no longer possible to misconfigure — the flag is
derived, not user input).
- Add `_sync_derived_flags()` helper called at every return path of
`detect_auth_mode` to set `settings.enable_login_flow` from the
resolved mode.
- `tests/unit/test_config_validators.py`: drop `enable_login_flow=True`
from happy-path fixtures (no longer needed — detection sets it).
Repurpose `test_login_flow_requires_enable_login_flow_flag` into
`test_login_flow_mode_auto_derives_enable_login_flow_flag` which
asserts the new auto-derivation behaviour for both LOGIN_FLOW and a
non-LOGIN_FLOW mode.
- `docker-compose.yml`: remove `ENABLE_LOGIN_FLOW=true` from the
`mcp-login-flow` and `mcp-keycloak` profiles.
- `env.sample`: remove the ENABLE_LOGIN_FLOW reference; the comment
on `MCP_DEPLOYMENT_MODE` now notes the derived flag.
- `docs/configuration.md`, `docs/authentication.md`,
`docs/login-flow-v2.md`, `docs/auth-flows.md`,
`docs/troubleshooting.md`, `docs/ADR-025-*.md`: replace
ENABLE_LOGIN_FLOW=true examples and references with
MCP_DEPLOYMENT_MODE=login_flow.
BREAKING CHANGE: `ENABLE_LOGIN_FLOW` is no longer read from the
environment. Anyone who relied on `ENABLE_LOGIN_FLOW=true` to activate
Login Flow v2 should set `MCP_DEPLOYMENT_MODE=login_flow` instead (or
rely on it being the default when no other auth env vars are set).

Follow-up to the LOGIN_FLOW rename. The user-facing surface area —
env.sample, docker-compose.yml mcp-login-flow profile, migration
guide, ADR statuses, and the running.md boot-log examples — all need
to refer to `login_flow` rather than the deprecated
`oauth_single_audience` string.
- docker-compose.yml: add explicit MCP_DEPLOYMENT_MODE=login_flow to
the mcp-login-flow profile (no longer relying on auto-detection).
- env.sample: update the deployment-mode list and example, dropping
the removed `oauth_token_exchange` and pointing at ADR-022 for the
rename rationale.
- docs/ADR-022: flip Status to Accepted with a note that this PR
implements step 1 (rename + validation gate).
- docs/ADR-021: note that it has been partly superseded by ADR-022
(the oauth_single_audience naming is no longer accurate); cross-link.
- docs/ADR-025: drop oauth_single_audience/keycloak from the dynaconf
validator example and the [oauth_single_audience] TOML section.
- docs/configuration-migration-v2.md: bulk-replace oauth_single_audience
→ login_flow throughout (sed -i).
- docs/running.md: re-collapse the per-mode boot-log subsections (added
during the closed PR #786 workaround) back into a uniform
"<mode>"-substitution block — now correct after this PR's logging
cleanup at app.py:1172.
No code changes in this commit.

Reviewer found two accuracy issues in the rewritten "Check Deployment
Mode" section:
- The AuthMode.OAUTH_SINGLE_AUDIENCE enum value is `oauth_single`, not
`oauth_single_audience` (config_validators.py:28). A user grepping
their container logs would have found nothing.
- The "Configuring MCP server for <mode> mode" line was presented as a
uniform <mode> substitution, but app.py:1170 hardcodes the literal
string `OAuth mode` for OAuth, while app.py:1239 uses the enum value
for the two BasicAuth modes.
Split the boot-time block into per-mode subsections so each one shows
the actual literal text users will see, and add a one-line note
calling out the OAuth string difference.

Issue #766 reported that the running.md quick-start tells users to
`curl http://localhost:8000/health`, which returns 404 — the server
only registers `/health/live` and `/health/ready` (K8s-style probes).
The same section also listed BasicAuth and OAuth startup log lines
(`BasicAuth mode detected …`, `OAuth mode detected …`) that no longer
exist anywhere in the codebase.
Update running.md and troubleshooting.md to point at the real
endpoints, explain liveness vs readiness, and replace the fictional
log examples with messages the server actually emits today. Also
clarify that the per-session BasicAuth messages only appear after the
first MCP client connects, which is the second symptom the reporter
hit.
Docs-only change; code paths and endpoint surface unchanged.

Round 17 reviewer (🟡 Important):
1. docs/configuration.md degraded-migration runbook said `doc_id backfill
failed on …` but the actual log line in qdrant_client.py:415 is
`doc_id backfill scroll failed on …`. Operators grepping the runbook
string would have missed it. Insert the `scroll` qualifier.
2. _create_one_payload_index returned True on the 400 schema-conflict
path, so a wrong-type index discovered at create time skipped the
consolidated `Payload index creation incomplete` summary — but a
wrong-type index discovered via the existing-schema check at line
195-206 did fire it. Tenants whose payload_schema is hidden from
their JWT (Qdrant Cloud collection-scoped tokens) only ever observe
the create-time path, so they never saw the operator-level summary.
Return False so the summary fires in both cases.
3. docs/configuration.md said the upgrade-time delay was `proportional to
point count while writes are issued` — overstating the cost. Writes
are proportional to int-typed points only; the scroll itself is
proportional to total point count. Reword.
Local-mode collection-creation regression (root-cause of failing
single-user / login-flow / multi-user-basic CI jobs):
PR #779 changed the existence probe in get_qdrant_client from
collection_exists() (returned bool in both modes) to get_collection()
+ except UnexpectedResponse(status_code=404). The HTTP-mode client
raises UnexpectedResponse with a 404 body, but the local/in-memory
client raises ValueError(f"Collection {name} not found") — see
qdrant_client/local/async_qdrant_local.py. The narrow except clause
let the ValueError propagate, app.py's lifespan re-raised as
RuntimeError, and the mcp container crashed on first start. Catch
ValueError too, with a `not found` substring guard so genuine
programming bugs (bad collection_name, etc.) still surface.
Tests: extend the existing 400-path test to assert the new
failed_fields contract; add two get_qdrant_client unit tests pinning
the local-mode VE catch (positive case + propagation case).

- Remove three stale `# Use numeric file ID` / `# Pass file path` comments
in scanner.py. file_id is already normalized to str() above each call
site, so the inline comments mislead readers.
- Wrap `_backfill_doc_id_to_string` scroll loop + sentinel upsert in
try/except Exception. The qdrant_client singleton is assigned before
this migration runs, so a transient scroll failure was leaving the
process holding a usable client with int payloads permanently
unbackfilled until the next restart. Catch broadly, log ERROR with
exc_info, and return without writing the sentinel — next process
restart retries from scratch.
- Note `:memory:` mode behavior near the sentinel constants so future
readers don't read the every-start scroll as a bug.
- Document the two degraded-migration ERROR log signals in
docs/configuration.md so operators know when a clean restart is
required to recover indexing.
- Add unit test asserting scroll-time exceptions are logged and swallowed
without writing the sentinel.
Closes round-4 review feedback on PR #773.

- _ensure_keyword_payload_indexes: distinguish 400 (schema conflict, warning)
from other status codes (5xx/network, error) so a transient outage doesn't
silently leave the collection unindexed.
- build_search_result_from_point: use .get("doc_id") + return None on missing
instead of KeyError-crashing the search; reverse metadata merge order so
payload-derived chunk_index/total_chunks win over caller-supplied extras.
- docs/configuration.md: restore the OpenAI/Mistral/Bedrock/Simple provider
sections + reference-table rows that were dropped in the rebase. Reword
the "Startup migrations" bullet to describe what the code actually does
(no sampling — full scroll, zero writes when clean). Add operator note
about the SemanticSearchResult.id TypeError path.
- tests: pytest.approx for float equality (Sonar python:S1244); coverage
for non-400 → ERROR, payload={doc_id: None}, and missing doc_id key.

Production was logging two cascading classes of Qdrant errors against the
welcomed-malamute deployment:
1. HTTP 400 — "Bad request: Index required but not found for \"doc_id\" of
one of the following types: [keyword]". The collection was created via
create_collection() with no payload indexes, so any FieldCondition
filter on doc_id failed at the Qdrant layer (placeholder writes/reads,
eviction, search context lookups).
2. Compounding the missing index, producers wrote a mix of int and str
doc_ids: webhook_parser stringified node_id, scanner stringified note
IDs, news IDs, and deck card IDs — but the file scanner passed the
numeric file_id through unchanged. A keyword index would not have
covered both kinds even if it had existed.
This change:
- Normalizes doc_id to str at every producer site (scanner.py:459,
DocumentTask.doc_id, indexed_*_ids reads from Qdrant).
- Tightens str|int annotations to str across placeholder.py,
eviction.py, search/verification.py, search/context.py,
SearchResult.id, and the auth/api visualization endpoints.
- Defensive str() coercion on doc_id reads in semantic.py /
bm25_hybrid.py / vector/visualization.py for the transition window
before the backfill runs.
- Adds an idempotent startup migration in get_qdrant_client():
- _ensure_keyword_payload_indexes creates KEYWORD indexes for
doc_id, user_id, and doc_type (tolerates "already exists" 400s).
- _backfill_doc_id_to_string scrolls the collection once and rewrites
int doc_ids to str. Skipped after a quick sample shows no legacy
int payloads.
- Public API preserved: SemanticSearchResult.id stays int via explicit
int(r.id) narrowing in server/semantic.py — surfaces a TypeError with
actionable context if a future doc_type ships non-numeric ids.
- Documents the startup migration in docs/configuration.md.
Tests: 11 new unit tests in tests/unit/vector/test_qdrant_client.py
covering happy path / already-exists / unrelated-400 for the index
helpers, and sample-skip / mixed-batch rewrite / payload=None edge cases
for the backfill. 889 unit tests pass.

- test_registry.py: stub `mistralai.client.Mistral` in
`test_registry_mistral_wins_over_ollama`, mirroring the sibling
picker test, so the test doesn't depend on the SDK accepting
arbitrary keys.
- openai.py: convert remaining f-string `logger.info(...)` calls to
lazy `%s` formatting, aligning with the pattern in mistral.py and
the repo's logging convention.
- test_mistral.py: add four tests covering the defensive RuntimeError
guards in `embed()` and `_embed_batch_request()` — empty
response.data, single null embedding, batch null embedding, and
count-mismatch.
- docs/configuration.md: add `AWS_ACCESS_KEY_ID` and
`AWS_SECRET_ACCESS_KEY` rows to the env-var reference table; they
were already mentioned in prose but missing from the table.

- _retry.py: replace `assert last_error is not None` with explicit
`if last_error is None: raise RuntimeError(...)` so the original
rate-limit error is preserved under `python -O`.
- openai.py: drop the `_retry_factory` alias chain; rename the bound
decorator to `_retry_429` to match the pattern in mistral.py.
- mistral.py: comment the imports so future reviewers understand why
`from mistralai.client import …` is the canonical path on 2.x (no
top-level `__init__.py`; no `mistralai.models` subpackage either).
- docs/configuration.md: add `OPENAI_GENERATION_MODEL` and
`OLLAMA_GENERATION_MODEL` rows to the env-var reference table.
- test_mistral.py: add direct unit test for the `_is_rate_limit`
predicate (429 → True, 500 → False, missing-attr → False).
- test_registry.py: stub `mistralai.client.Mistral` in the registry
picker test, mirroring the Ollama sibling, so the test doesn't
depend on the SDK accepting arbitrary keys.

Adds a hosted Mistral embedding option (mistral-embed, 1024-dim) alongside
the existing Bedrock / OpenAI / Ollama / Simple providers. Implementation
mirrors OpenAIProvider: lazy dimension detection with a known-models lookup,
chunked batch requests, defensive index sort, and a 429-aware retry decorator.
In the same change, ProviderRegistry switches from os.getenv to the
dynaconf-backed Settings dataclass so all five providers share a single
configuration path. config.py gains the previously-uncovered Bedrock keys,
the new Mistral keys, the missing OPENAI_GENERATION_MODEL /
OLLAMA_GENERATION_MODEL, and SIMPLE_EMBEDDING_DIMENSION.
Auto-detection priority: Bedrock → OpenAI → Mistral → Ollama → Simple.

Hide sensitive files/folders from the WebDAV MCP tool surface by
tagging them with a configured Nextcloud system tag. Defence-in-depth
control for users who connect LLMs to accounts holding contracts,
medical records, credentials, etc.
A new EXCLUDED_TAGS env var (comma-separated tag names, empty by
default) gates an exclusion layer that runs at the start of every
WebDAV tool call: tag names are resolved to tag IDs, those IDs are
expanded to the set of tagged paths, then listings/searches are
filtered and read/write/delete/move/copy operations on excluded paths
raise ToolError. Tagged folders exclude their descendants via prefix
match. Empty EXCLUDED_TAGS disables the feature entirely.
The threat model is preventing accidental data exfiltration via the
LLM tool surface — not hiding files from a determined operator. The
docs explicitly recommend creating exclusion tags with
user_assignable=false so the credentials the MCP server uses cannot
remove the tag.
Implementation:
- config.py: add `excluded_tags` to _DEFAULTS, Settings, and the
_field_map alongside other comma-separated env vars.
- client/webdav.py: get_files_by_tag now requests <d:resourcetype/>
and surfaces is_directory so tagged directories can recursively
exclude descendants.
- server/tag_exclusion.py (new): get_excluded_tag_names,
get_excluded_file_paths, is_path_excluded.
- server/webdav.py: exclusion guards in all 11 WebDAV tools;
read/write/create/delete/move/copy raise ToolError, list/search
tools silently filter excluded entries. Existing f-string log
calls converted to lazy %-style.
- tests: 17 new unit tests covering path-matching edge cases
(shared-prefix non-match, descendants of excluded dirs), tag-name
parsing, and get_excluded_file_paths with mocked WebDAV; 1 new
client test asserting <d:resourcetype/> -> is_directory parsing.
- docs/configuration.md: new "Tag-Based File Exclusion" section with
per-tool effect table, security guidance, and per-call cost note.
- README.md: feature mention under Key Features.
Closes#710.

Three findings from the latest review on #758 (1 medium, 2 low):
Medium:
- browser_oauth_routes.oauth_logout: move delete_browser_session into a
finally block so an error from delete_refresh_token can no longer leave
an orphan browser_sessions row. The orphan was not exploitable
(SessionAuthBackend rejects sessions without a live refresh token), but
it lingered until the hourly cleanup cron — a correctness gap. New
regression test pins the fix.
Low:
- oauth_callback_nextcloud: drop redundant ``or None`` from
``expected_nonce=nonce``. ``nonce`` is already ``str | None`` and
``secrets.token_urlsafe`` never produces an empty string, so the
coercion was a no-op that could mislead future readers into thinking
empty-string was a valid skip-the-check path.

Calls out the apps-to-install matrix (user_oidc required, oidc skip,
astrolabe optional), the OIDC clients to register and what each is for,
the per-app scope advertisement requirement on the IdP side, and the
"OAuth succeeded but Nextcloud returns 401" diagnosis path.

- Rename `verified_count` → `verified_chunk_count` to make the count
granularity explicit at the field name (chunks vs unique docs).
- News verifier now fails open *per-item* on non-numeric stored doc_ids
(matches notes/files/deck shape); a single bad id no longer rescues
definitively-missing siblings from eviction.
- Update note-verifier integration test to use string doc_ids end-to-end
to match production storage (scanner.py:241 stringifies note ids).
- Add regression test for the closed-task-group race guard in
`verify_search_results` so the RuntimeError swallow is locked in.
- Convert remaining f-string logger calls in `server/semantic.py` to
lazy %-style formatting (per repo convention).
- Document `evict_on_missing` as a developer/test flag (no env var) and
flag the `get_file_info` 404→raise contract change in its docstring.
- Add a TODO(ADR-019) breadcrumb for the hardcoded 2× over-fetch so
future tuning has a clear hook.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Closes out the remaining nits flagged in the round-6 review.
Critical:
- _verify_files contract comment now enumerates all None-return cases
(404 + malformed PROPFIND XML) and documents the false-eviction
trade-off; self-healing via re-indexing recovers
- int(r.id) cast at the SemanticSearchResult boundary now raises a
TypeError with explicit doc_type/value context instead of bubbling
up as an opaque "Search failed: ..." McpError
Design observations:
- nc_semantic_search_answer docstring documents the per-note
round-trip cost from the post-verification race guard
- News verification latency hint added to configuration.md
- SemanticSearchResponse exposes verified_count + dropped_count so
short result pages on high-ghost-density indexes are
distinguishable from genuine scarcity. verify_search_results now
returns (kept, dropped_count); production caller and tests updated
Minor:
- Comment clarifies the .get() fallback in verify_search_results is
defensive only (run_verifier always populates the entry)
- Eviction task-group guard narrowed from except Exception to
except RuntimeError (the only documented failure mode of
TaskGroup.start_soon on a closed group)
- Indexer logs a warning when a deck_card task is missing
board_id/stack_id, surfacing data-quality issues at index time
rather than at verification time
- New unit test covers the news verifier's non-numeric-id fail-open
path (one bad doc_id keeps the entire batch)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Tightens verifier consistency, closes test gaps, hardens the fire-and-forget
eviction snapshot, and routes the new concurrency knob through Settings.
- Pre-flight ``int()`` guard in ``_verify_notes`` mirrors ``_verify_deck_cards``,
so a non-numeric note id produces a type-specific log line instead of
falling through to the generic "unexpected error" branch.
- Adds explicit 403 tests for the file and news verifiers (symmetry with the
existing notes/deck 403 tests) plus a ``non_numeric_id_keeps`` test.
- ``AppContext`` and ``OAuthAppContext`` no longer snapshot
``_vector_sync_state.eviction_task_group`` at lifespan-yield time. Both
expose it as a ``@property`` that reads the singleton dynamically, removing
the order-sensitive race where a future startup-ordering change could
silently degrade fire-and-forget eviction to inline forever.
- Adds ``verification_concurrency`` (env var ``VERIFICATION_CONCURRENCY``,
default 20) to ``Settings`` with a dynaconf validator; ``verify_search_results``
resolves the cap lazily from settings when the caller doesn't override it.
- Enriches the news verifier TODO to call out that ``batch_size=-1`` is
intentional — a numeric ceiling would silently break correctness because
any item beyond the cap would be missing from ``present_ids`` and dropped.
- Updates ``Optional[TaskGroup]`` to ``TaskGroup | None`` per project style.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Guard eviction_task_group.start_soon against shutdown race so a
RuntimeError on a closed group never surfaces as a search error.
- Correct ADR-019 news_item row: there is no per-item REST endpoint;
verification batches via get_items(batch_size=-1) and intersects.
- Modernize models/semantic.py typing to PEP 604 / lowercase generics
per CLAUDE.md.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- _verify_deck_cards: hoist int(board_id|stack_id|doc_id) out of the generic
except Exception into an explicit try/except (TypeError, ValueError) before
the network call, mirroring _verify_news_items. Malformed payloads now log
a specific warning instead of "unexpected error".
- _verify_news_items: add TODO(perf) above the get_items(batch_size=-1) call
to mark the known fetch-all cost as a future profiling target.
- SemanticSearchResult.id: revert from int|str back to int. The internal
SearchResult.id stays int|str for forward-compat; the MCP response model
narrows at the boundary. server/semantic.py casts r.id to int when
constructing the response so future string-id types fail loudly here
instead of silently widening the public API.
- nc_semantic_search: replace the terse "extra for access filtering" comment
with an ADR-019 NOTE block explaining the 2x over-fetch trade-off and the
ghost-density under-delivery case (self-heals via lazy eviction).
- tests/integration/test_verify_on_read.py: extend the module docstring to
call out that only the note verifier is exercised against real Nextcloud,
while file/deck_card/news_item are unit-only — documenting the suite split
for future contributors.
- ADR-019: rewrite "Module shape", "Verifier registry", example verifier,
and "Deduplication" sections to match the shipped BatchVerifier interface
(was per-id Verifier in the original draft). Add a "Why batch?" paragraph
explaining the design choice. Update implementation checklist — every
item is now [x] with corrected verifier names (plural) and the eviction
module path (vector/eviction.py).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Implements fire-and-forget eviction (ADR-019 §"Lazy eviction"): the
search response no longer waits on Qdrant deletes, instead spawning
evict() on a long-lived lifespan-owned task group. Falls back to inline
eviction in modes without vector sync and in unit tests.
Also: harden _verify_news_items against non-numeric ids (fail open
instead of crashing the verifier); document the get_file_info None-on-404
contract; add INDEXED_DOC_TYPES single source of truth in vector/scanner.py
referenced by the CI-guard test; write a Verify-on-Read Latency Budget
section in docs/configuration.md covering the unbounded news.get_items
fetch. Closes the two remaining ADR-019 implementation checklist items.

- Cap all_results to limit*2 after sort in the per-doc_types branch of
nc_semantic_search to bound over-verification (was unbounded N-types).
- Switch BatchVerifier from (client, doc_ids, user_id) to (client, results,
semaphore). Verifiers now read file paths and deck board/stack ids from
SearchResult.metadata instead of doing fresh Qdrant scrolls — eliminates
one duplicate round-trip per file/deck-card verification.
- Bound per-id verification concurrency with a shared anyio.Semaphore
(default 20, matching server/semantic.py context-expansion convention).
Prevents httpx pool exhaustion / rate limiting on large search pages.
- Propagate stack_id from Qdrant payload to SearchResult.metadata in both
bm25_hybrid.py and semantic.py (board_id was already propagated).
- Drop now-unused _resolve_file_path / _resolve_deck_metadata helpers.
- Drop redundant int(d) in requested predicate from _verify_news_items.
- Rewrite eviction comment to be honest about inline (not background)
execution and the resulting latency coupling.
- ADR-019 status: Proposed -> Accepted.
- Add news property to NextcloudClientProtocol.
- Widen SearchResult.id and SemanticSearchResult.id to int | str to match
BatchVerifier signature and document support for future string-id types.
- Flip openWorldHint to True on nc_semantic_search_answer (it calls into
Nextcloud via nc_semantic_search).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The vector index lags Nextcloud (5-min webhook cron + scanner interval),
producing ghost records for deleted/unshared documents until the next
reconciliation. Verify each unique document against Nextcloud at query
time, drop inaccessible results, and lazily evict the corresponding
Qdrant points.
Per-doc_type batch verifiers: notes/files/deck cards run concurrently
per id; news items use a single fetch + intersect to avoid the per-item
fetch-all amplification. Transient errors fail open (keep result, log
warning) — only definitive 4xx drops. Multiple chunks of the same doc
collapse to one verification call.
Wired into nc_semantic_search before the limit trim and before context
expansion. nc_semantic_search_answer's per-note re-fetch retained as a
sub-second race guard since verification now happens upstream.

Address four small items from the latest PR #743 review:
- login-flow-v2.md Compose example: add an inline comment +
follow-up note pointing readers at Docker secrets for
TOKEN_ENCRYPTION_KEY (the snippet is likely to be copy-pasted
into production).
- auth-flows.md: rename the third column in the Astrolabe → MCP
Server diagram from "Nextcloud OIDC" to "OIDC Provider" so the
diagram matches the multi-IdP framing in the surrounding prose.
- login-flow-v2.md OAuth Endpoints section: rewrite the
ambiguous "token issuance still comes from the IdP" line to
make the cryptographic separation explicit — the MCP server
exposes /token, but tokens are signed by the IdP's key and
validated against its JWKS; the MCP server has no signing keys
of its own.
- README.md auth bullet: replace the jargony "OAuth-to-MCP
supported, with app-password conversion to Nextcloud" with the
reviewer's clearer wording: "MCP clients authenticate via
OAuth, the server handles Nextcloud app passwords
transparently".
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The docs claimed scopes are mcp:-prefixed (mcp:notes.read,
mcp:notes.write) and that the notes.* pair "covers all Nextcloud
apps". Both are false. Per @require_scopes decorators across
nextcloud_mcp_server/server/, scopes are unprefixed and per-app:
notes.read/write, talk.read/write, files.read/write,
calendar.read/write, contacts.read/write, deck.read/write,
news.read, tables.read/write, cookbook.read/write,
todo.read/write, collectives.read/write, sharing.write,
semantic.read, plus standard OIDC scopes.
Changes:
- login-flow-v2.md: replace the false 2-row "covers all apps"
scope table with the real per-app reference (links to
scope_authorization.discover_all_scopes() as authoritative
source); strip mcp: prefix from intro paragraph, sequence
diagrams, @require_scopes example, WWW-Authenticate header
example. Also fix sticky-session keying advice per reviewer:
route on user identity (sub claim) rather than the raw bearer
token, since tokens rotate on refresh.
- auth-flows.md: clarify "Astrolabe (hosted UI) → MCP" matrix
column header; strip mcp: from sequence diagram and key
characteristics bullet; correct "issued by MCP server" to
"issued by configured IdP" on the Login Flow v2 token.
- authentication.md: strip mcp: from the high-level diagram and
scope-enforcement prose; cross-link to the scope reference.
- configuration.md: add NEXTCLOUD_OIDC_CLIENT_ID,
NEXTCLOUD_OIDC_CLIENT_SECRET, and OIDC_DISCOVERY_URL to the
Login Flow v2 vars table — these were undocumented in the
table after the round-2 multi-IdP fix.
- running.md: drop deprecated `version: '3.8'` from compose
snippets (Compose v2 ignores it and emits warnings).
- testing-oidc-consent.md: fix sample authorize URL and consent
description to use real scope names instead of mcp:-prefixed
ones (the manual test as written would have failed with
invalid_scope).
- CLAUDE.md: replace dead links to deleted oauth-architecture.md,
oauth-setup.md, and audience-validation-setup.md with
login-flow-v2.md.

Previous round narrowed the framing too far in the other direction —
made it sound like Nextcloud OIDC is *the* IdP. The MCP server
actually supports any OIDC-compliant provider (Nextcloud's built-in
OIDC, Keycloak, AWS Cognito, Auth0, etc.) selected via
`OIDC_DISCOVERY_URL`. `NEXTCLOUD_OIDC_CLIENT_ID/SECRET` are generic
OIDC client credentials despite the Nextcloud-flavored naming.
Code references:
- IdP discovery: app.py:607-668 (auto-detects integrated vs external
by comparing discovered issuer to NEXTCLOUD_HOST)
- JWKS: unified_verifier.py:71-73 (dynamically discovered, not
hard-coded to Nextcloud)
- IdP selection knob: OIDC_DISCOVERY_URL (config.py)
Changes:
- login-flow-v2.md: redraw "How It Works" diagram to show the IdP as
a separate component; replace "Nextcloud OIDC" with "configurable
IdP" framing throughout; add OIDC_DISCOVERY_URL to the env-var
reference; clarify NEXTCLOUD_OIDC_CLIENT_ID/SECRET are generic OIDC
creds; rename "OAuth Endpoints" subtitle to point at "the configured
IdP".
- running.md: rewrite the OAuth Mode intro and Quick Start note to
mention IdP configurability and OIDC_DISCOVERY_URL.
- configuration.md: update Best Practices "For Production" multi-user
bullet to reference the IdP selector and generic-creds caveat.
- auth-flows.md: generalize Astrolabe-flow and Login Flow v2
characteristics bullets — IdP and JWKS source are configurable.
- keycloak-multi-client-validation.md: REMOVE the "deprecated"
banner I added in 35c115e. The doc covers active behavior in
external-IdP mode (realm-level token validation by user_oidc),
not retired direct-OAuth-to-Nextcloud architecture. Replaced with
a scope note pointing at when this applies.
oauth-impersonation-findings.md keeps its deprecation banner — that
doc *is* about the rejected service-account / impersonation path
(ADR-002 Tier 2, "Will Not Implement"), so the deprecation framing
remains correct there.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The previous round of review feedback rested on a misunderstanding —
that the MCP server is "the OAuth issuer" under Login Flow v2 and that
NEXTCLOUD_OIDC_CLIENT_ID/SECRET are external-IdP-only. Code says
otherwise (app.py:619/625/703-717, unified_verifier.py:72):
- The MCP server is an OIDC relying party of Nextcloud OIDC. Tokens are
signed by Nextcloud and validated against Nextcloud's JWKS in all
modes — the server has no private signing keys.
- Static NEXTCLOUD_OIDC_CLIENT_ID/SECRET are the preferred way to
register the MCP server as that relying party; RFC 7591 DCR is a
fallback when both are unset.
- Login Flow v2 layers per-user app-password acquisition on top — it
governs the MCP→Nextcloud data leg, not the relying-party setup.
This commit reverts the inaccuracies introduced by 35c115e and reframes
the original `login-flow-v2.md` to match what the code does:
- login-flow-v2.md: revise "How It Works" to describe the MCP server
as an OIDC RP + OAuth facade (not a standalone issuer); rename
"OAuth Issuer Endpoints" → "OAuth Endpoints" with a note that those
endpoints front Nextcloud OIDC; add NEXTCLOUD_OIDC_CLIENT_ID/SECRET
to the required env vars with DCR documented as fallback.
- running.md: restore the static-creds Docker example (deleted in
35c115e on the wrong reasoning that it was tied to the retired
direct-OAuth-to-Nextcloud flow); rewrite the OAuth Mode section
intro to describe the actual relying-party + facade architecture.
- configuration.md: fix Best Practices "For Production" to mention
static creds as preferred / DCR as fallback; restore the .oauth
Docker volume alongside data so DCR-registered MCP-client state and
the encrypted app-password DB both persist.
- auth-flows.md: drop the note added in 35c115e that wrongly claimed
the MCP server validates Bearer tokens against its own JWKS under
Login Flow v2 — it validates against Nextcloud's JWKS in all modes;
reword the Login Flow v2 "Key characteristics" bullet that called
the MCP server "the OAuth authorization server".

Round-2 cleanup of PR #743 review comments not covered by d153e96:
- configuration.md: fix broken `#multi-user-oauth-modes` anchor; replace
with the two real anchors (Multi-User BasicAuth, Login Flow v2). Rewrite
the stale "always use OAuth2/OIDC with pre-configured clients" Best
Practices section to reflect the post-pivot mode matrix, and update the
Docker volume example to mount the encrypted app-password store
(`TOKEN_STORAGE_DB`) rather than obsolete `.oauth` client storage.
- semantic-search-architecture.md: rename remaining body references from
the deprecated `VECTOR_SYNC_ENABLED` to `ENABLE_SEMANTIC_SEARCH` so the
doc matches configuration.md / troubleshooting.md.
- running.md: relabel "OAuth Mode (Recommended)" as
"Login Flow v2 / OAuth issuer mode (--oauth)", drop the misleading
"(Legacy)" suffix from BasicAuth, drop the
`NEXTCLOUD_OIDC_CLIENT_ID/SECRET` example (tied to the retired
direct-OAuth-to-Nextcloud flow), and add a note explaining what
`--oauth` actually enables post-pivot.
- keycloak-multi-client-validation.md, oauth-impersonation-findings.md:
add a deprecation banner pointing at ADR-022 / Login Flow v2. Files
retained because ADR-002 and CLAUDE.md still cite them.
- auth-flows.md: clarify under the Astrolabe → MCP diagram that the
Nextcloud-OIDC JWKS path applies to Multi-User BasicAuth; under
Login Flow v2 the MCP server validates tokens against its own JWKS.
- login-flow-v2.md: clarify the sticky-session note — affinity must key
on the OAuth bearer token (or user-bound cookie), not source IP, since
MCP clients may not maintain stable IPs across the provisioning flow.

Many identity providers (AWS Cognito, Okta, Azure AD) reject or mishandle
colons in OAuth scope names. This migrates all custom scopes from

MCP clients like Claude Code were unable to use tools because tokens
obtained directly from Nextcloud had the wrong audience claim. The MCP
server now acts as its own OAuth Authorization Server, proxying auth
to Nextcloud with its own client_id so tokens have the correct audience.
New endpoints: /.well-known/oauth-authorization-server, /oauth/token,
/oauth/register. Modified /oauth/authorize from pass-through to
intermediary pattern. PRM now points authorization_servers to the MCP

Proposes consolidating five deployment modes into two:
- Single-User: App password in env vars (trusted environment)
- Multi-User: Login Flow v2 for per-user app password acquisition
Key changes:
- Use Nextcloud Login Flow v2 (NC 16+) for delegated authentication
- Application-level scope enforcement (app passwords have no native scopes)
- MCP elicitation for seamless authorization prompting
- Astrolabe front-end integration for scope management UI
- Clear security posture documentation for administrators
This removes the need for upstream Nextcloud OAuth patches and simplifies
deployment while maintaining security through defense-in-depth.
