Claude Fable 5	9b7acab294	#232: plugin allowlist with SHA-256 hash pinning ... The install path records the SHA-256 of the delivered bundle ZIP (plugins.bundle_hash; pre-#232 installs show it as unknown until reinstalled). plugins.allowlist in instance_settings names permitted ids with their pinned hashes: empty (default) = not enforced, existing instances unchanged; non-empty = installs of unlisted or deviating bundles are rejected (plugin_not_pinned / plugin_hash_mismatch, 403), and an installed plugin outside the list or with a deviating hash does not load — absent from pond mount lists, frame/assets 404. Every rejection is audited (plugin.rejected, catalogue v1.5). A version bump changes the hash and therefore requires an explicit re-pin — the intended friction (ADR 0025). Admin UI shows observed vs pinned hash per plugin with pin/re-pin/unpin. Scope stated honestly in plugin-architecture.md: the pin answers "is this the reviewed bundle"; post-install disk tampering is platform integrity (ADR 0019), sandbox containment stays the sandbox's job. Hardening guide row + catalog advisory triage; residual risk R-03 resolved. e2e: empty-allowlist compatibility, pinned load, unpinned and tampered installs rejected and audited, pin drift blocks loading while the admin still sees the mismatch, version bump needs re-pin.

Claude Fable 5	4c7f001cab	#215: trusted reverse-proxy header / mTLS client-certificate path ... 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. Refs #215.

Claude Fable 5	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). Refs #214.

Claude Fable 5	2bdb0ec2cf	#224: read-trail storage — partitioning, retention, admin query path ... 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.

Claude Fable 5	488d0d06f1	#205: classification inherits down the tree; lowering is a guarded, audited act ... New pages take max(instance default, parent level); moving a subtree under a higher-classified parent raises every member below that level. No move-like path (reposition, trash-promote, purge-promote) lowers a level as a side effect — pinned by test. Raising is ordinary editorial work; lowering requires the dedicated capability canLowerClassification (pond-wide Pond Admin) in the central permission model. Both directions are audited (page.classification_raised/_lowered, catalogue v1.1) with old value, new value, actor and page.

Claude Fable 5	000d110727	#201: stable audit event catalogue for syslog/SIEM export ... The 36 audit action ids become a typed union (AUDIT_EVENTS in audit-actions.ts) — an uncatalogued id is now a compile error; every existing id keeps its name. The published, versioned catalogue (docs/architecture/audit-events.md, v1.0) documents per event: trigger, severity, actor and target semantics, and every field, plus the compatibility promise (ids are never repurposed; retiring keeps the row forever) and the stable stdout field set. audit-catalogue.test.ts is the fence: it parses the document's event tables and fails when ids or severities drift from the code (negative case verified). Audit stdout lines now carry the catalogue severity as a routing hint — pino level stays 30 so transport is unaffected; no DB migration. Forwarding path documented: container stdout -> operator's collector; deliberately no application-side syslog client.
