From 127298f1f907855ad07f870fb3b528436dd6314c Mon Sep 17 00:00:00 2001 From: Duncan Date: Thu, 6 Aug 2026 16:17:26 -0400 Subject: [PATCH 01/28] feat(acp): implement permission policy (#4938) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a three-value BUZZ_ACP_PERMISSION_POLICY (allow | ask | reject) that gates how session/request_permission calls are handled: - reject (headless default): synchronous denial, byte-for-byte unchanged from today's dontAsk behavior; ResolvedPermissionConfig derives dontAsk mode so the adapter self-denies before Buzz sees the request. - allow: synchronous auto-selection of the unique allow_once option from the exact options in the request; zero/multiple allow_once candidates or malformed options fail closed with a denial. Never allow_always, never hardcoded IDs. - ask: interactive — emits an acp_read telemetry frame with an authorization envelope (requestNonce, actionable, reason) and registers a pending entry in a bounded map (cap=8) on AcpClient. The desktop delivers a permission_decision control frame carrying the nonce and chosen optionId; the read loop matches by nonce, validates the optionId against the captured option snapshot, and writes the ACP response. Per-request timeout min(300s, remaining hard deadline) fails closed. Key implementation details: - ResolvedPermissionConfig computed once at startup; transmits effective_mode via set_config_option for every agent that advertises the mode field (goose skipped). - Admission preflight (synchronous, before map insertion): options nonempty, count ≤ 16, every optionId unique+nonempty, required kind/name fields, duplicate live requestId → immediate denial with original untouched, map at cap → deny, serialized payload ≤ OBSERVER_MAX_PLAINTEXT_LEN. - Cancel during writing → PermissionPoisoned error: surfaces through cancel_with_cleanup_grace so classify_control_cancel_failure triggers respawn (not pool return). PermissionPoisoned added to is_transport_error. Pending entries drained with cancelled responses before session/cancel. - ask without observer or unresolved owner downgrades to reject with a loud warning. - acp_read generic emit suppressed for ask permission requests; replaced with a single post-preflight enveloped emit (one frame per request). - Decision receiver arm placed ahead of reader arm in the biased select! for inbound fairness. - ObserverEvent gains optional authorization: Option with skip_serializing_if. Payload bytes remain raw ACP, never mutated. - NIP-AO.md reconciled: adds authorization envelope, permission_decision control type, control_result telemetry kind, switch_model control type, single-use nonce semantics, best-effort delivery with mandatory timeout, cancel-during-write poison behavior, and 5-minute desktop live lookback. Tests: 720 passing (31 new pinned tests covering mode matrix, admission preflight, allow selector, ask map lifecycle, cancel-during-writing poison, policy × mode combinations, and decision arm behavior).

add to `RESERVED_ENV_KEYS` so users cannot override via env-vars UI - Include `permission_policy` in `SpawnSnapshot` / restart-diff so edits surface in the existing `needsRestart` flow - Expose `permission_policy` + `permission_policy_source` on `ManagedAgentSummary` (resolved values) - Extend `UpdateManagedAgentRequest` with double-Option `permission_policy` (None = unchanged, Some(None) = clear, Some(Some(v)) = set); reject edits to remotely deployed agents with a clear error message - Add remote-deployed agent path in `agents_deploy.rs`: read per-record policy, fall back to desktop default, inject into `policy_env` **TypeScript (desktop/src)** - `PermissionPolicy = "ask" | "allow" | "reject"` and `PermissionPolicySource = "agent" | "global_default" | "built_in"` in `types.ts`; add to `ManagedAgent`, `CreateManagedAgentInput`, and `UpdateManagedAgentInput` (null = clear per-agent override) - `tauri.ts`: add `permission_policy` / `permission_policy_source` to `RawManagedAgent` with safe defaults; map in `fromRawManagedAgent` - `agentSessionTypes.ts`: add `authorization?: { requestNonce, actionable, reason? }` to `ObserverEvent`; extend `lifecycle` `TranscriptItem` with `requestNonce`, `actionable`, `authorizationReason`, `options` - `agentSessionTranscript.ts`: add `pendingPermissionsByNonce` map; parse `authorization` envelope from `session/request_permission` events; handle `control_result/permission_decision` to retire cards on terminal outcomes, including the pinned uncertain message - `agentControl.ts`: add `sendPermissionDecision(pubkey, nonce, optionId)` fire-and-forget control API - `LifecycleActivity.tsx`: `PermissionDecisionButtons` component renders per-option buttons styled by kind (reject_* = destructive); local pending state with retry on error; rendered when `actionable && !outcome` - `AgentInstanceEditDialog.tsx`: permission policy select (Inherit / Ask / Allow / Reject) for local agents; read-only for remote-deployed agents with a shutdown+redeploy hint;

Terminal outcomes arrive as enveloped acp_write frames correlated by requestNonce. The card retirement matrix will be wired once Thufir's review of Duncan's buzz-acp contract lands and NIP-AO is pinned. Updated the control_result handler to preserve card actionability on delivery — the PermissionDecisionButtons component already handles button-level pending-state reset via its own catch handler if the fire-and-forget send fails.

keep reject+auto hard error; auto is a model classifier not bypass mode (per adapter source review) - Dead state: Writing(String) -> Writing; is_permission_poisoned() removed; PermissionMode::is_default #[cfg(test)] - Tests: decision loop success, bad optionId idle-timeout, annotated-size preflight, malformed reject_once fallback, updated cancelled behavior tests Desktop (desktop/): - Thread channelId through PermissionDecisionButtons and sendPermissionDecision() - Key permission cards by nonce; fallback to turn-based key for legacy paths - control_result non-sent: set deliveryFailed on card; buttons re-enable via useEffect; add deliveryFailed field to TranscriptItem lifecycle type - Fleet-wide permission_policy: add to TS GlobalAgentConfig, EMPTY_GLOBAL_CONFIG, and AgentDefaultsEditor fleet defaults select control - Remote deploy: pass caller-resolved policy to build_launch_block; resolver tests in permission_policy.rs; deploy tests for all three policy sources - Terminal outcomes: timed_out and uncertain (pinned copy) in describePermissionOutcome - Tests: nonce-keyed card, concurrent cards, auth envelope, fallback key, channelId threading, delivery-failed/sent control_result (9 new) NIP-AO (docs/nips/NIP-AO.md): - switch_model: describe actual behavior;

The absence of a nonce is the replay guard; no tombstones means capacity counts only live (Pending|Writing) requests, fixing the 9th-request-in-one-turn bug. - Add finish_permission() terminal helper owning Pending→Writing→Resolved for all terminals. Exactly one write+flush, exactly one nonce-correlated authorized acp_write with the terminal reason. Any write failure poisons the process and emits a permission_terminal observer-only event so Desktop can retire the card (the uncertain path). - Cancel path: write failure also poisons and emits permission_terminal. cancel-during-write emits permission_terminal for the in-flight entry. - Re-arm idle deadline when live pending count reaches zero so a slow human decision grants a fresh idle window instead of insta-cancelling the turn. - Capacity check now counts only live (Pending|Writing) entries. - Clippy: fix assert_eq!(x, true) → assert!(x), while-let-loop, doc overindented list items in acp.rs and config.rs. - Fmt: cargo fmt applied. Desktop (agentSessionTranscript.ts): - acp_write authorized frames correlate exclusively by authorization.requestNonce (primary); JSON-RPC id correlation is a legacy fallback for non-ask paths. - Terminal copy derives from authorization.reason (applied/timed_out/cancelled/ uncertain) via describePermissionTerminalReason — timeout now renders 'Timed out' not 'Denied (reject_once)'. - set actionable: false on all retirement paths. - permission_terminal observer event handler retires the card via nonce. - turn_completed and turn_error backstop: retireAllLivePermissionCards() retires any still-live cards so missing telemetry and archive replay cannot reconstruct live controls. - Biome format applied. lib.rs: - fit_observer_event_to_budget: early return without mutation when event.authorization.is_some() — authorized frames are never leaf-trimmed or stubbed (NIP-AO §3 byte-for-byte requirement). - Enqueue suppresses over-cap authorized frames entirely (defense in depth). - Test: test_authorized_frame_payload_is_never_trimmed. Tests: - ask_production_path_emits_request_captures_nonce_and_delivers_decision: real script emits session/request_permission, harness captures nonce from in-process observer, routes decision through channel, asserts end_turn. - cancel_writes_exactly_one_response_per_pending_id_no_replay: registers entries via production path, captures nonces before cancel, verifies each emitted cancel nonce matches a registered entry nonce, verifies no replay. - ask_permission_idle_is_suspended_while_pending_entry_exists: paused-time, asserts entry present at 299s. - ask_permission_deadline_fires_at_300_seconds: paused-time, asserts entry removed at exactly 300s. - ask_permission_idle_rearmed_after_last_entry_resolves: paused-time, proves idle deadline re-armed after decision applied. - ask_nine_sequential_requests_all_succeed_after_capacity_recovery: nine sequential requests each decided before the next is queued; asserts 9 distinct authorized acp_write observer nonces. NIP-AO.md: - session_resolved = session establishment (not terminal). - Added turn_completed and turn_error rows as terminal lifecycle events. - uncertain path: permission_terminal observer event replaces wrong session_resolved reference.

Before this change, emit_permission_read_non_actionable generated its own nonce internally while the caller passed a different nonce to finish_permission_sync, producing one logical challenge/answer pair with two different nonces. Desktop's nonce-only correlation rule left the read card live because the write could never find it by nonce. Fix: accept nonce as a parameter in emit_permission_read_non_actionable (removing its internal new_permission_nonce() call) and drop the now-dead caller_will_emit_read parameter from handle_permission_request and emit_permission_read_with_nonce. Upgrade two tests from telemetry-proxy assertions to direct pipe proofs: - ask_permission_entry_deadline_equal_to_loop_hard_deadline_writes_denial_before_exit: replace observer telemetry assertion with a capture script that reads the denial line from child stdin NDJSON and parses the wire response. - cancel_first_write_fails_stops_immediately_no_second_write: add a write-attempt counter (Arc in write_ndjson_inner) to assert exactly ONE attempt was made and the loop stopped, not just that no successful writes occurred. Add Rust tests proving the nonce is shared: - sync_denial_malformed_options_read_and_write_carry_same_nonce - sync_denial_preflight_failure_read_and_write_carry_same_nonce Add TypeScript reducer tests: - buildTranscript_sync_denial_write_with_matching_nonce_retires_card - buildTranscript_sync_denial_write_with_mismatched_nonce_leaves_card_live Update NIP-AO schema prose and observer.rs field comment to explicitly document the permission_terminal exception to the authorization-only-on- acp_read/acp_write rule.

The six permission-policy additions to tauri.ts that were within the old headroom now exceed the tighter baseline. Extract RawManagedAgent type and fromRawManagedAgent function into a dedicated shared/api/managedAgentMapping.ts module (mirrors main's editMessage.ts pattern). tauri.ts re-exports both for zero caller changes. Removes now-unused imports (ManagedAgentBackend, PermissionPolicy, PermissionPolicySource, RawRestartDiffEntry). Result: tauri.ts 1073 gate vs 1161 allowed (88-line margin).

Parser (permissionRequest.ts): - Discriminated union PermissionRequestPending | PermissionRequestResolved aligned to the frozen schema (event b31c716e): requestNonce, sessionId, turnId, optionIds[], labels{}, hasDurableRule, durableRuleNote, outcome, chosenOptionId, originalEventId. - All untrusted display strings capped at 200 chars; optionIds bounded to 10. - extractPermissionRequest() and stripPermissionRequestSentinel() are render-safe (never throw). Compute helper (computePermissionRequest.ts): - D1 signer gate: kind-9 must be signed by the channel's known agent pubkey. - Edit authenticity: resolved state accepted only from kind-40003 signed by the original agent (not owner, not attacker). - selectProseOrPermission() mirrors selectProseOrNudge() from configNudge. Card (permission-request-card.tsx): - Pending: renders option buttons from optionIds + labels[optionId]. Deny-style button heuristic uses label text (opaque optionIds carry no semantic). ExpiryCountdown ticks down to expiresAt; expired cards show 'Timed out'. D5 durable-rule disclosure (durableRuleNote) shown below buttons when hasDurableRule is true. - Resolved: shows outcome label derived from outcome + chosenOptionId. - Actionable buttons gated: isOwner && state === 'pending' only. - sendPermissionDecision() is fire-and-forget; button disables on click with 'Decision sent'; re-enables on relay error so the user can retry. Integration (MessageRow.tsx, formatTimelineMessages.ts, types.ts): - editSignerPubkey threaded from formatTimelineMessages through TimelineMessage so the edit authenticity gate has the raw event signer without re-querying. - PermissionRequestCardBlock wraps useIdentityQuery to resolve the current viewer, computes isOwner, and renders the card when a trusted sentinel is present. React.memo with custom comparator keeps MessageRow re-render budget clean. Auth helper (permissionRequestAuthPubkey.ts): - getPermissionRequestAgentPubkey() returns the agent pubkey only for known-agent-signed kind-9 events, mirroring getConfigNudgeAuthorPubkey. Tests: 33 named tests covering all 6 frozen fixtures verbatim plus rejection cases (bad version, unknown state, size bounds, malformed JSON, field invariants) and the full signer/edit-authenticity gate matrix.

Sentinel publish system (buzz-acp): - Add relay_publisher, agent_relay_keys, agent_owner_pubkey_hex, turn_initiator_pubkey, sentinel_channel_id, sentinel_thread_reply_id fields to AcpClient; wired per-turn from pool.rs and lib.rs. - D7-final admission check: Ask only fires for owner-initiated turns when relay_publisher is present; non-owner turns silently downgrade to reject so no card is posted for unattended sessions. - kind-9 sentinel published after inserting the pending entry; event ID stored in PermissionEntry::sentinel_event_id for the edit. - kind-40003 resolved edit published in finish_permission Ok path; skipped when sentinel_event_id is None (relay-absent sessions). - Both publishes are fire-and-forget; permission flow never blocks on relay acceptance. - publish_event_acked / PublishEventAcked / AckOutcome scaffolding preserved for future acked-publish callers. Label fix (desktop): - describePermissionOutcome: accepts optionLabels (display strings) and optionKinds (for deny/approve verb only) as separate maps; never renders raw ACP kind strings to the user. - describePermissionTerminalReason: builds optionLabels from label ?? name fields; raw kind string falls back to verb-only ("Approved" / "Denied") when no display string is available. - Legacy key path passes empty labels map (verb-only fallback). Documentation (NIP-AO.md): - Permission Sentinel Cards section: kind-9/40003 lifecycle, D7-final admission check, D5 durable-rule disclosure, sentinel authenticity. Tests: - 736 + 9 buzz-acp unit tests pass (sentinel publish skipped via relay_publisher: None in test helpers; D7 gate bypassed when relay_publisher is None). - agentSessionTranscriptPermissions.test.mjs: 12 named tests for describePermissionOutcome and describePermissionTerminalReason. - computePermissionRequest.test.mjs: tests for sentinel card parser. - Updated expectations in agentSessionTranscript.test.mjs and ingestArchivedObserverEvents.test.mjs to match verb-only fallback.

Specifically: - config.rs: BypassPermissions variant reintroduced with no guard in PermissionConfig::resolve; test_default_config_uses_bypass_permissions asserted effective_mode == DontAsk - pool.rs: ResolvedPermissionConfig replaced with bare PermissionMode, relay_event_publisher/permission_decision_tx stripped, sentinel wiring removed from run_prompt_task, doc comments spliced mid-sentence - acp.rs: test helpers options()/outcome() deleted while call sites remained (5 E0425 compile errors); find_allow_once_returns_none_when_absent body corrupted with undefined `response` variable - lib.rs: import regression Fix: restore all four crates/buzz-acp files to the branch tip (d808c4bd) which correctly supersedes both #4609 and its revert #5323. No semantics from the revert survive on this branch.

From fe7efd8aabb9f35766c4125ef12e051aa78e3aa0 Mon Sep 17 00:00:00 2001 From: Duncan Date: Sat, 8 Aug 2026 15:56:39 -0400 Subject: [PATCH 18/28] fix(acp): ACK-gated sentinel lifecycle, D7 admission, NIP-AO docs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the frozen ACK-waiter contract for the ask permission policy: - Publishing→Pending→Writing/Terminal lifecycle: entry inserted as Publishing before publish; transitions to Pending only on relay OK accepted=true. Non-accepted outcomes (Rejected, timeout at min(10s, expiresAt), socket failure) deny immediately (fail closed). - Registration-before-send via register_publish_ack: background relay task inserts the ACK waiter before sending the EVENT frame. - Early-decision buffering: an authorized decision arriving while still in Publishing is stored in early_decision and applied on admission with no additional round trip. - Exactly-once terminal consumption: ack_result_rx arm, timeout check, and cancel path each consume the record exactly once via finish_permission / finish_permission_sync. - Remove the D7 !relay_active escape hatch: admission now requires publisher AND byte-equal initiator==owner; missing relay context denies synchronously with the D7 diagnostic, zero card events. - Store wire expiresAt once in PermissionEntry at build time; kind-40003 resolved edit reuses it with no recompute drift. - Add test_pair_rejecting, test_pair_silent, test_pair_dead to RelayEventPublisher for the ACK lifecycle test matrix. - Fix test compile errors: IdleTimeout(Duration), remove test_from_cmd_tx dependency, add allow(collapsible_match). - NIP-AO: replace published-immediately with ACK-gated admission semantics including fail-closed paths and early-decision note.

A new select arm in the main event loop fires at the earliest deadline, calling sweep_expired_ack_waiters — which removes every expired entry and sends Uncertain — so the map is provably empty on every path (timeout, socket failure, disconnect drain, late OK no-op) without requiring caller participation. Caller-side changes: register_publish_ack accepts the computed publish_deadline and forwards it to the background task via the PublishEventAcked command. The spawned ACP task no longer wraps ack_rx in a timeout_at; the relay bg task guarantees the channel resolves before the deadline. SENTINEL_PUBLISH_TIMEOUT_SECS promoted to pub(crate) so relay.rs can reference it in publish_event_acked's default deadline.

Unknown kinds also rendered as green Allow (Wes: should fail closed). Tighten PermissionDecisionButtons: - allow_once → actionable green Allow button (unchanged path) - reject_* family → actionable red Deny button (unchanged path) - allow_always → non-actionable amber badge: "Permanent grant — use request card". The thread card (D5 disclosure) is the correct surface; the observer feed is advanced/debug and should not offer one-click durable grants. - Unknown kinds → silently omitted (fail closed); no button rendered. Add LifecycleActivity.render.test.mjs with five cases covering allow_once, reject_once, allow_always (badge present, no button), unknown kind (nothing rendered), and a mixed allow_once + allow_always card.
