Addresses all 9 findings from the review on PR #758:
Blocking:
- _revoke_refresh_token_at_idp now reads config from oauth_ctx["config"]
(the production-shaped nested dict). Previously read flat keys, causing
IdP revocation to silently no-op in production. Test fixtures rebuilt
to the realistic nested shape so the bug can't regress unnoticed.
- HTML error responses in oauth_login_callback now wrap IdP-controlled
error_body, str(e), and the attacker-controlled error/error_description
query params in html_escape. New test_browser_oauth_xss.py pins this.
Important:
- New _safe_next_url helper validates the ?next= query param at write
time (oauth_login), in oauth_logout, and on read from the session row
in oauth_login_callback. Blocks https://, // (protocol-relative), and
CRLF/whitespace injection.
- verify_id_token now caches discovery + JWKS (5-min TTL) using the
same pattern as oauth_routes._get_cached_discovery. New caching
regression test pins to one fetch per URL across multiple calls.
- /oauth/logout is now POST-only at the route layer (defeats passive
CSRF via <img src>). oauth_logout also validates Origin/Referer
against the configured mcp_server_url. Logout UI in user_info.html
converted from <a href> to <form method="post">.
- New storage.cleanup_expired_browser_sessions() called from the hourly
cleanup loop in app.py — previously these rows accumulated for users
who never explicitly logged out.
Nits:
- Demoted INFO logs that leaked oauth_config.keys() / client_id /
token-storage state to DEBUG. Operator-relevant outcome lines
(login successful, refresh token stored, logged out) stay INFO.
- verify_id_token algorithms widened to RS256, PS256, ES256 — covers
Azure AD (PS256) and Cognito/some Keycloak realms (ES256). Symmetric
and "none" remain off the allowlist.
- Migrated all Optional[X] usages in auth/storage.py to X | None per
CLAUDE.md.
Breaking change: GET /oauth/logout now returns 405. The in-tree logout
UI was migrated to a POST form; any external bookmark or curl-based
caller that relied on GET will need to switch.

Three review items from the third-round review on PR #757:
- scope_authorization: split the combined logger.warning(error_msg) in
the require_scopes decorator's missing-app-password branch into two
lazy %-style logger calls (one per branch), keeping the f-string
error_msg for the exception only. The else branch also logs the
elicit_result for diagnostics. Bypassing lazy %-interpolation in
security-sensitive code formatted the message regardless of log level
and matched the repo-wide lazy-logging preference; the new code now
conforms.
- config + browser_oauth_routes: wire COOKIE_SECURE through Settings
(cookie_secure: bool | None = None) so _should_use_secure_cookies()
reads it via get_settings() rather than os.getenv. Completes the
consolidation pass that touched this file in commit 7464340 and
removes the last raw os.getenv from browser_oauth_routes.py
(import os dropped). Dynaconf auto-coerces "true"/"false" → bool;
"1"/"0" arrive as int and are normalised by an explicit bool() at
the consumer.
- elicitation: clarify the _astrolabe_settings_url docstring to call
out that the empty-string case is also a None-return path (matches
the existing `if not base:` guard).

Pre-launch hardening for the hosted Astrolabe Cloud offering. Addresses
all five findings raised in #626 (Tim Kaufmann, code review of v0.65.0).
Re-verified against master before fixing.
Finding 3 (LLM-controllable user_id) — drop user_id from the public
signatures of provision_nextcloud_access, revoke_nextcloud_access,
check_provisioning_status, check_logged_in. Tool wrappers now always
derive identity from the verified AccessToken; user_id is no longer
accepted as MCP input. Adds parameterized CI-guard test that locks the
schema.
Finding 2 (predictable session cookie) — replace mcp_session=<user_id>
cookie with a cryptographically random session_id mapped server-side
(new browser_sessions table, alembic 005). Cookie value is opaque,
expires, revocable. SessionAuthBackend looks up user_id via the new
mapping and additionally requires a refresh token to fail closed.
Finding 4 (logout doesn't revoke refresh token) — oauth_logout now
calls the IdP revocation_endpoint (RFC 7009) when advertised, deletes
the stored refresh token regardless, and clears the browser_sessions
row. Cleanup is best-effort: logout always 302s.
Finding 1 (unverified ID token decodes) — verify_id_token helper does
JWKS signature + issuer + audience + exp + nonce checks per OIDC core
3.1.3.7. Used by both OAuth callback handlers (browser + MCP). Removes
the four "verify_signature: False" decodes that previously trusted IdP
claims unconditionally. Drops dead-code _validate_token_audience in
token_broker. Refactors token_utils + provisioning_decorator to read
user_id from the verified AccessToken instead of re-decoding the JWT.
Finding 5 (hardcoded Fernet keys in docker-compose.yml) — replace the
three inline TOKEN_ENCRYPTION_KEY values with required env var
interpolation; document in env.sample.
Test coverage: 4 new unit test modules (signature pinning, browser
sessions, ID-token verification, logout + revoke + session backend).
693 unit tests pass; ruff/format/ty clean.
Migration note: existing browser admin-UI sessions become invalid on
rollout (cookies are looked up against the new browser_sessions table,
which starts empty). Users re-login. MCP API access is unaffected.
Tracked on Astrolabe Cloud POC board card #37.

The elicitation flow points users to the Astrolabe web route or the
BasicAuth REST endpoint to provision their app password. Both paths
stored the password without clearing the in-process scope cache, so a
user who provisioned through them would keep hitting
ProvisioningRequiredError for up to _SCOPE_CACHE_TTL (5 min) afterwards.
Add invalidate_scope_cache(user_id) to both write-paths (matching the
existing pattern in nc_auth_check_status), correct the now-misleading
comment in scope_authorization.py to name all three invalidation paths,
and add a one-line hint above the first elicitation patch in the test
file so future authors don't "fix" the patch target to the wrong module.

Four review items from the second-round review on PR #757:
- scope_authorization: broaden the post-elicit retry message to acknowledge
the 5-minute scope-cache TTL — if the LFv2 poller is still in-flight at
acknowledge-time, the immediate retry can still hit a stale cache.
- elicitation: extract a shared `_run_elicit(ctx, message, schema, *,
log_label)` helper so `present_login_url` and
`present_provisioning_required` no longer duplicate the
hasattr-guard / try-NotImplementedError / try-Exception fallback block.
The data-acknowledged warning specific to login-flow stays in
`present_login_url` so behaviour is preserved exactly.
- elicitation: detect missing http:// / https:// scheme in
`_astrolabe_settings_url`, log a warning, and return None — caller
renders the safe tool-only fallback instead of producing a broken link.
New unit test locks this in.
- browser_oauth_routes: replace the stray
`os.getenv(\"NEXTCLOUD_HOST\")` in `_should_use_secure_cookies` with
`get_settings().nextcloud_host` for consistency with the rest of the
file (PR #757 review nit).

Lift NEXTCLOUD_PUBLIC_ISSUER_URL out of raw os.getenv reads into
Settings.nextcloud_public_issuer_url across all 8 production call sites
(app.py x2, oauth_routes.py x2, browser_oauth_routes.py,
provision_routes.py, userinfo_routes.py, elicitation.py). cli.py
remains the env-write source so the existing config-by-flag pipeline
still works.
Also addresses remaining PR #757 review nits:
- elicitation.py: align URL-present/absent wording on "open in your
browser" so users don't try clicking in the terminal
- test_scope_authorization_stored.py: lock in the deliberately-shared
fall-through branch with explicit declined/cancelled decorator tests
- test_elicitation.py: switch from monkeypatch.setenv to
patch(get_settings) since Settings is now the canonical surface
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Branch the ProvisioningRequiredError message on the elicit result so a
user who acknowledged the prompt isn't told to call
nc_auth_provision_access (which would loop an LLM that just confirmed
via elicitation). Other paths keep the existing instruction.
- Convert present_login_url's f-string logger.warning to lazy %s, matching
present_provisioning_required and the repo's lazy-logging preference.
- Add a test for NEXTCLOUD_PUBLIC_ISSUER_URL trailing-slash normalization.
- Strengthen the decorator-elicits test: split into the "accepted" and
"message_only" branches so the error-message change is regression-tested.

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.
Mined from the cbcoutinho/nextcloud-mcp-server#752 thread.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
When a tool requiring Nextcloud access is called without a stored app
password (Login Flow v2 mode), the @require_scopes decorator now invokes
MCP elicitation with a clickable Astrolabe settings URL — reconstructed
from NEXTCLOUD_PUBLIC_ISSUER_URL / NEXTCLOUD_HOST — before raising
ProvisioningRequiredError. Clients without elicitation support fall back
to the existing text error.
Surfaced by cbcoutinho/nextcloud-mcp-server#752, where users hit a 401
after OAuth and had no clickable URL to start Login Flow v2 from.

Six review items raised; four required code changes (#3, #4, #5, #6) and
two were resolved without code changes (#1 audit-only, #2 informational).
* search/verification.py — clarify the granularity asymmetry between the
whole-batch fail-open (structural API failure) and the per-item fail-open
(single bad stored doc_id). Future readers no longer need to derive why
the two paths have different blast radii from the code alone.
* models/semantic.py — `dropped_document_count` description now explicitly
notes that subtracting it from `verified_chunk_count` is not a meaningful
operation, since the two fields count different units (documents vs
chunks). Surfaces the unit mismatch where MCP clients actually see it.
* server/semantic.py — clarify the per-doc_type over-fetch comment so the
N×2 pre-merge Qdrant cost (vs the cross-app branch's 1×2) is explicit
rather than implied by "same 2× over-fetch budget".
* tests/unit/search/test_verification.py — add four new 429 unit tests
(notes/news/files/deck) mirroring the existing 5xx-keeps pattern. Locks
in that `_is_definitive_404_or_403` returns False for 429 so a future
refactor cannot accidentally treat rate-limit responses as permanent
revocations.
Audit confirmation for review item #1: all four `WebDAVClient.get_file_info`
call sites already handle the new `HTTPStatusError`-on-404 contract
(verification.py:156, tests/integration/test_rag.py:139,
tests/unit/client/test_webdav.py:153/190). No silent breakage internal to
this repo.

Deployer role:
- Add servicediscovery actions; module always creates Cloud Map namespace
and service so the policy must grant CreatePrivateDnsNamespace etc.
- Make Route53 + ACM permissions unconditional. The server module always
issues an ACM cert and writes Route53 records (no CloudFront default-cert
path exists), so gating these on route53_zone_ids was broken. Split
Route53 into hosted-zone management (always) plus record-set mutation
(scoped to caller-supplied zones, falls back to *).
- Remove unused cloudfront:* statement; no CloudFront resources in module.
- Replace acm:* wildcard with explicit cert-management action set.
Server module:
- qdrant_image_tag is now nullable with default null and validated against
use_external_qdrant, so external-qdrant callers can omit it instead of
passing a sentinel "unused" value.
- task_role_arn and efs_id outputs marked sensitive; qdrant_dns_name returns
null when use_external_qdrant = true.
- ALB SG now has matching IPv6 egress rule (was v4-only).
- nextcloud_url validates the https:// scheme.
- random_pet.subdomain keeper includes zone_name so a zone migration that
preserves zone_id still triggers regeneration.
- Pin required_version >= 1.9 on both modules.

Three minor fixes from the round-11 review on PR #750:
- bm25_hybrid.py:209 — Comment said `doc_id` is `int (notes) or str (files)`,
which is backwards. Notes, news_items, and deck_cards are stored as `str`
(scanner.py:241, 666, 867); files are stored as `int` (scanner.py:425).
Updated to point readers at scanner.py as the source of truth.
- verification.py:338 — Lowered the News-API 403/404 log line from `info`
to `debug`. The News app being uninstalled or disabled is a predictable
operational state (matching the other verifiers' debug-on-not-found
paths), so this should not generate operator-dashboard noise. Transient
errors immediately below stay at `warning` because they're unexpected.
- semantic.py:809 — `nc_get_vector_sync_status` was reading
`document_receive_stream` via `getattr(..., None)`, but the attribute is
guaranteed-defined on both `AppContext` and `OAuthAppContext` (as a
field with `None` default). The defensive `getattr` masked typos that
the eviction_task_group access at semantic.py:197-199 deliberately
surfaces. Switched to direct access; the `if … is None:` value-check
below is preserved (the attribute can legitimately be None before sync
starts).
Items deliberately deferred (with rationale in the plan file):
- News verifier semaphore-hold during get_items (reviewer: "not required
here, just worth tracking"; ADR already lists follow-ups).
- Hardcoded 2× over-fetch / VERIFICATION_OVERFETCH (TODO already in code).
- Integration test for the real Qdrant eviction filter (reviewer marked
low-priority; type-preservation chain is unit-tested).

- Add concurrency-safety comments to per-verifier accessible sets in
_verify_notes/_verify_files/_verify_deck_cards. Same rationale as
accessible_by_type in verify_search_results: anyio is cooperative,
set.add() is not an await point.
- Document 401 exclusion in _is_definitive_404_or_403 (treated as
transient because it usually signals expired credentials, not
permanent denial).
- Note multi-user compounding in the news verifier semaphore comment:
N concurrent users hold N slots out of the shared budget.
- Log inaccessible doc ids with a type tag (e.g. "int:42" vs "str:42")
so ghost-record logs disambiguate id types.
- Type the BatchVerifier alias and the four verifier function signatures
with NextcloudClientProtocol instead of Any (algorithms.py exposes
the right interface; the protocol is runtime_checkable).
- Surface verified_chunk_count vs dropped_count semantics in the
nc_semantic_search tool docstring Returns block (chunks vs unique
documents).
- Add comments to the two max_concurrent=20 sites in server/semantic.py
noting they are intentionally distinct from
settings.verification_concurrency (different request phases).

Address findings surfaced by `pre-push-review` after the round 8 sweep:
- Add deck verifier symmetry tests (404, transient 5xx, unexpected
exception, non-numeric metadata) so deck has the same shape as the
notes/news/files verifiers. Also add unexpected-exception tests for
the news and file verifiers, which had `except Exception` branches
no test was reaching. Keeps the registry-style verifier coverage
uniform.
- Modernize sibling field types in `VectorSyncState`, `AppContext`,
and `OAuthAppContext` from `Optional[X]` to `X | None`, matching the
`eviction_task_group: TaskGroup | None` field added in the round 8
diff (resolves the inconsistency flagged by A6). The lone remaining
`Optional` import is dropped.
- Reverse cross-reference direction in the verifier docstrings: the
later-defined `_verify_deck_cards` and `_verify_news_items` now
point at `_verify_notes` as the canonical hoisted-cast pattern,
rather than `_verify_notes` forward-referring to verifiers defined
below it.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- 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>
Round 7 raised 5 issues; this round addresses all of them and fixes
the underlying causes (not just the comments) where applicable so
they don't get re-flagged in future passes.
Critical:
- verified_count description in SemanticSearchResponse said "unique
documents" but the value is len(verified_results), a chunk count.
Description rewritten to accurately document chunk-level granularity
AND explicitly call out the asymmetry with dropped_count (which
counts unique (doc_id, doc_type) pairs).
- _verify_files false-eviction risk: the round-6 doc-only fix was
re-flagged. Address at the source — widen WebDAVClient.get_file_info
to raise HTTPStatusError on 404 (matching the rest of the client
convention) and reserve None for the genuinely ambiguous
malformed-PROPFIND case. _verify_files now keeps the result on None
(cannot tell whether the file exists) and evicts only on a
definitive HTTPStatusError 404. Tests updated; new test added for
the malformed-XML keep-result path.
Non-critical:
- News verifier semaphore lifetime now explicitly documented: one
slot held for one deduplicated fetch per search is the correct
backpressure behaviour.
- Cross-reference comments in _verify_notes / _verify_deck_cards no
longer claim "Mirrors X" pointing at functions defined later in
the file; now use direction-neutral "parallel implementation in".
- accessible_by_type is mutated by concurrent run_verifier tasks; a
comment explains why this is race-free under anyio's cooperative
multitasking (distinct keys per task, no await between read and
write) so a future reader doesn't add a redundant lock.
- Knock-on: tests/integration/test_rag.py wraps get_file_info in a
try/except for the new contract.
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 round-5 reviewer feedback on PR #747:
- Escape `webhook_uri` in the admin pane HTML template so an operator-
controlled env value (`WEBHOOK_INTERNAL_URL`, `NEXTCLOUD_MCP_SERVER_URL`)
can't inject markup. The sibling `preset_id` and exception messages were
already escaped — this one was the odd one out.
- Convert the eight remaining f-string `logger.warning`/`logger.error`
calls in `api/webhooks.py` to lazy `%s` formatting, matching the style
already adopted by `webhook_receiver.py` and `webhook_routes.py`.
- Document why the 401 from `handle_nextcloud_webhook` deliberately omits
`WWW-Authenticate`: NC's webhook delivery worker has no auth-flow state
machine to negotiate against, the bearer is a static shared secret
configured out-of-band via `WEBHOOK_SECRET`, and a challenge response
wouldn't change client behaviour. The existing warning log already
records the rejection.

Address the two Security findings from PR review:
- webhook_receiver: encode Authorization header and expected bearer to
utf-8 bytes before hmac.compare_digest. Conventional form; doesn't
rely on Python's implicit ASCII encoding.
- webhook_routes: html.escape user-influenced and exception-derived
strings before interpolating into HTMLResponse content. Covers the
preset_id path param echoed in the "Unknown preset" branch and the
str(e) text rendered on handler exceptions.
Adds regression tests verifying compare_digest is invoked on bytes and
that <script> payloads (in preset_id and exception messages) are
emitted as escaped entities, not active markup.
