For perimeters that authenticate before the application (ADR 0021 §4).
Off unless BOTH AUTH_PROXY_HEADER and AUTH_PROXY_TRUSTED_PEERS are set —
nothing about the header is guessed. The peer check runs against the TCP
peer address only (a forwarded header is attacker-influenced): a request
carrying the header from any other peer is rejected outright and audited
as auth.proxy_rejected (catalogue v1.4) — that is a spoof attempt, not a
misconfiguration — even when a valid session cookie rides along. From a
trusted peer the header IS the identity; a session cookie never
escalates beyond it; with the feature off the header is inert.

Mapping is explicit (AUTH_PROXY_MAP: username or e-mail); deliberately
no just-in-time creation — the header carries no verified address. The
mTLS variant (AUTH_PROXY_MODE=mtls-dn) maps the configured attribute
(default CN) out of the certificate subject DN the TLS terminator
forwards, under the same peer rules. Session-less proxy requests key the
read trail per user (user:<id>).

The trust boundary is stated in security.md (the section an assessor
reads closest), the VS-NfD security documentation and the hardening
guide's deploy table. Tests cover all four decisions: off = inert,
trusted peer authenticates (username and DN mapping), untrusted peer
rejected + audited, no escalation past a session cookie.

5796b7a5dd #214: OIDC Authorization Code with PKCE, Keycloak as reference IdP

External authentication (ADR 0021) built on jose (#188's vetted library)
plus fetch — no new dependency enters the supply chain for a security
base function. Discovery-configured; ID tokens validate against the
IdP's JWKS under an explicit RS256/ES256 allowlist with issuer,
audience, expiry and nonce binding. State, nonce and the PKCE verifier
travel in a signed HttpOnly Lax cookie keyed by a dedicated HKDF
purpose (oidc-state, ADR 0020).

Deploy-level configuration (OIDC_ISSUER/CLIENT_ID/CLIENT_SECRET/SCOPES/
PROVIDER_LABEL): who authenticates users is a platform decision. The
login page discovers the provider via GET /auth/methods and renders the
SSO button (i18n de+en).

Identities use the existing slot (provider oidc:<issuer>, subject from
the token). First login creates the account just-in-time — ACTIVE and
mail-verified only when the IdP asserts a verified address. An existing
local account is NEVER adopted silently by e-mail (account-takeover
path): login refuses with oidc_link_required and the owner links
explicitly via GET /auth/oidc/link (audited auth.identity_linked,
catalogue v1.3). Sessions come from the one existing session service.

Tests run the full flow against a protocol-faithful fake IdP: PKCE
verifier at the token endpoint, JIT creation incl. personal pond,
invalid state/nonce/signature/issuer/audience/expiry each rejected, the
linking refusal and the explicit link flow. Verified end-to-end against
a real Keycloak 26.0 (repeatable procedure documented in security.md
§External authentication).

New instance switch readTrail.enabled, default OFF: read logging is
employee monitoring in a works council's eyes — an ordinary instance
must not surveil reads. Off means no event is written ANYWHERE (no row,
no stdout line, verified by test); the api announces the switch position
once per boot, so an eventless trail is never ambiguous — a gap reads
as "was off", never "was lost".

The written purpose limitation ships as section 7 of the VS-NfD
security documentation (#228): what is recorded (no content, no titles,
no IPs, no fingerprinting), why (evidence for reads of marked content
only — variant A is the technical anchor of the promise), who may read
it (Site Admin, API-only), for how long (readTrail.retentionDays,
audited pruning), and what it may NOT be used for (no performance or
behaviour monitoring). The hardening guide's reference configuration
turns the trail on (reference value true) and points to that text; the
existing trail suites now enable the switch explicitly.

2bdb0ec2cf #224: read-trail storage — partitioning, retention, admin query path
Some checks failed

CI / Import/export fidelity gate (pull_request) Has been skipped

Convert read_events to monthly RANGE partitions on occurred_at, with a
DEFAULT partition as safety net: a lagging maintenance job must never
turn the trail's hard-failure semantics into an outage for classified
reads. The dedup unique pair (#223) moves to per-partition indexes
(PostgreSQL cannot carry it on the parent); a bucket spanning a month
boundary may record one duplicate — over-recording is acceptable, gaps
are not.

New daily job read-trail-maintenance (job-count fence 9 -> 10) creates
months ahead — each with its dedup index — and applies the trail's own
retention readTrail.retentionDays (default 365, deliberately independent
of audit.retentionDays): whole expired months are DROPped without
scanning, remainders deleted by range, every run audited as
read_trail.pruned (catalogue v1.2; the fence regex now admits an
underscore namespace).

Site-Admin query path GET /admin/system/read-events answers "who read
page X" and "what did user Y read" within a period — API-only by
design, documented. Growth measured and documented in data-model.md:
~1 MB per 1000 events including indexes.

Tests: retention pruning + audited deletion + admin queries on the
shared database; the partitioned shape, per-partition P2002 dedup,
months-ahead creation and DROP-based pruning against a fresh database
built by the real migration chain.

fd4fd60c99 #223: dedup window for the read trail
Some checks failed
CI / Lint, typecheck, test (pull_request) Successful in 6m29s

One event per (session, page, channel) within an aligned window of
readTrail.dedupWindowMinutes (default 5): buckets are
floor(epoch / windowSeconds), and a unique (dedup_key, window_bucket)
pair collapses concurrent duplicates race-free at insert time — the
first access in a window is always recorded, a later duplicate lands on
the unique violation and is skipped quietly (a skipped duplicate is not
a gap; only real write failures still abort the read). Each row carries
windowSeconds, so the evidence states it represents a window, never a
request count.

Reconnects within a window stay one event; a new session records again
even for the same user; channels never collapse into each other; the
page-less attachment key uses the documented `-` placeholder. Load
evidence: 30 collab-token renewals inside one window produce exactly one
event (test), bounding a live editing session at ~12 events/hour/page.

Window semantics documented in ADR 0023, the VS-NfD security
documentation (#228) and as a hardening-guide line for the new setting
(care rule: same PR).

2c6eff85f3 #227: hardening guide with the VS-NfD reference configuration
docs/vs-nfd/50-haertungsleitfaden.md: one adoptable profile — every
entry with the exact switch name, value, default and the reason, split
into instance settings (registration closed, api/mcp off, feeds off,
plugins off, classification defaults vs_nfd + upload block, svg reject,
minimal extension list) and deploy-level configuration (empty
BACKUP_ALLOWED_TARGETS enforces backup-local-only outside Site-Admin
reach; tightened session hours; SMTP deliberately unconfigured with the
consequence stated honestly). auth.local.enabled is listed as the one
pending row (#216) with its compensation until then; the guide states
the binding updated-in-same-PR rule for every future switch. Includes
an operator verification checklist (four unauthenticated 404 curls +
readyz + admin spot checks). Cross-referenced from the delimitation
statement (file names made concrete) and consumed by the Grundschutz
mapping (#230).
