From 936c1009eee6ac4c3898d423487c7da4ab2f9eaa Mon Sep 17 00:00:00 2001 From: Duncan Date: Mon, 10 Aug 2026 11:08:50 -0400 Subject: [PATCH 01/25] feat(desktop): move persisted secrets from JSON into keyring via gen-ref protocol MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All three secret tiers (global env vars, per-agent env/auth_tag/ provider_config, definition env vars) now move from plaintext JSON into the existing SecretStore keyring blob using an immutable generation-reference protocol: - Each write creates a new immutable generation entry under a UUID- keyed coordinate (e.g. agent::env:). The stripped JSON carries a non-secret *_ref field; the atomic JSON write is THE commit point. - Crash before JSON commit: old ref stays authoritative, orphaned gen is swept by GC. Crash after: new ref is authoritative, old gen swept. - Empty vs unavailable distinguished by ref presence: no ref = field intentionally empty (agent runs); ref present but entry missing = unavailable, fail closed (nsec-style refusal). - Inline precedence: on keyring write failure (Windows TooLong / backend error) value stays inline in 0o600 JSON with a named warning and the ref is cleared. Inline is authoritative over any keyring state for that boot; extraction retries next boot. - Two-cycle GC: sweep 1 marks unreferenced generations as candidates in the blob; sweep 2 (next verified boot) deletes still-unreferenced candidates. Saves cancel their generation's candidacy before the JSON commit. GC is a no-op when either JSON store is absent, unreadable, or changes between reference collection and blob mutation. - Boot migration runs at the end of run_boot_migrations_inner (after materialize_agent_runtimes) so raw-JSON migrations see inline values. - OSS keyringless builds are unchanged (inline 0o600 JSON). Coordinates: global:env: agent::env: agent::auth_tag: agent::provider_config: (entire BackendKind::Provider.config) definition::env: Files changed: secret_store.rs — add remove_keys() for batch blob deletion managed_agents/mod.rs — expose secret_projection module managed_agents/secret_projection.rs — new: full gen-ref protocol impl + tests managed_agents/types.rs — add auth_tag_ref, env_vars_ref, provider_config_ref managed_agents/global_config — add env_vars_ref, hydrate-on-load/strip-on-save managed_agents/storage.rs — hydrate/strip seam, migration helpers migration.rs — boot migration + two-cycle GC commands/agents.rs — new ref fields initialised to None commands/personas/snapshot/import.rs — same commands/team_snapshot.rs — same Deferred (noted in PR body, not a separate issue): existing nsec blob (~2.8 KB) already exceeds the Windows 2,560-byte cap — pre-existing, same accepted-risk class as the overflow path added here.

Previously, runtimes like claude/codex (which pass agent_readiness without API-key checks) would show local_setup = true even when spawn was blocked by spawn_key_refusal. The flag was already wired to spawn refusal; this closes the status gap. - Legacy Sprout app-data agents dir cleanup: migrate_legacy_app_data_dir copies the old xyz.block.sprout.app agents/ into Buzz but leaves the source. cleanup_secret_artifacts now also runs on the legacy source dir after a verified extraction boot, scrubbing backups and deleting .invalid/temp artifacts from the Sprout-era plaintext store. - Phase 2 artifact cleanup tests: add filesystem-backed tests for atomic-write temp deletion, .invalid deletion, parseable-backup scrub, symlink escape (unix-only), and deletion-failure tolerance. These cover the cleanup_secret_artifacts inventory that the spec requires.

charset=UTF-8 Content-Transfer-Encoding: 8bit Commit the three items that were in working-tree state but not pushed: - types.rs: add secrets_unavailable: bool field (transient, #[serde(skip)]) to ManagedAgentRecord with doc comment explaining load-time semantics - secret_seam.rs: set record.secrets_unavailable = true when hydration errors are present, making the setter actually wire unavailability into the record - storage.rs: extend spawn_key_refusal to check secrets_unavailable (in addition to empty nsec), refuse spawn with a named error message; update comments at both load_managed_agents callers to reflect that unavailability is now set directly on the record and consulted by spawn_key_refusal - storage.rs: add migrate_agent_secrets_to_dev_service (v2 marker, separately versioned from _dev_migration_v1) covering canonical dev → prod and scoped dev → canonical dev, with conflict detection, global:env ref check, and collect_global_env_refs helper - migration.rs: wire migrate_agent_secrets_to_dev_service into the boot path (cfg(debug_assertions), after migrate_inline_secrets_to_keyring) - secret_projection.rs: add test_cancel_before_mark_ordering_protects_in_flight_gen covering the cancel-before-mark scenario Paul flagged (step 4 safe: a marked- then-referenced gen survives the next boot's delete phase) - All struct literal sites updated with secrets_unavailable: false Co-authored-by: Will Pfleger Signed-off-by: Will Pfleger --- .../src/commands/agent_config_tests.rs | 1 + desktop/src-tauri/src/commands/agents.rs | 1 + .../src-tauri/src/commands/agents_tests.rs | 1 + .../commands/personas/delete_cascade_tests.rs | 1 + .../personas/inbound/inbound_tests.rs | 1 + .../personas/snapshot/fidelity_tests.rs | 1 + .../src/commands/personas/snapshot/import.rs | 1 + .../src/commands/personas/snapshot/tests.rs | 1 + .../personas/update/name_propagation_tests.rs | 1 + .../src-tauri/src/commands/team_snapshot.rs | 1 + .../src/commands/team_snapshot/tests.rs | 1 + .../src/managed_agents/agent_events.rs | 1 + .../managed_agents/agent_snapshot_envelope.rs | 1 + .../managed_agents/agent_snapshot_tests.rs | 1 + .../config_bridge/reader_tests.rs | 1 + .../src/managed_agents/discovery/tests.rs | 1 + .../managed_agents/effective_config/tests.rs | 1 + .../src/managed_agents/global_config/tests.rs | 1 + .../src/managed_agents/nest/tests.rs | 1 + .../src/managed_agents/parallelism.rs | 1 + .../managed_agents/persona_events/tests.rs | 1 + .../src-tauri/src/managed_agents/readiness.rs | 1 + .../managed_agents/runtime/test_fixtures.rs | 1 + .../src/managed_agents/secret_projection.rs | 109 ++++++++++ .../src/managed_agents/secret_seam.rs | 1 + .../managed_agents/spawn_snapshot/tests.rs | 1 + .../src-tauri/src/managed_agents/storage.rs | 201 +++++++++++++++++- .../src/managed_agents/storage_tests.rs | 143 +++++++++++++ .../src/managed_agents/team_snapshot.rs | 1 + .../src/managed_agents/teams_tests.rs | 1 + desktop/src-tauri/src/managed_agents/types.rs | 10 + desktop/src-tauri/src/migration.rs | 8 + 32 files changed, 490 insertions(+), 8 deletions(-) diff --git a/desktop/src-tauri/src/commands/agent_config_tests.rs b/desktop/src-tauri/src/commands/agent_config_tests.rs index ad636c6f487..2a92f75e4aa 100644 --- a/desktop/src-tauri/src/commands/agent_config_tests.rs +++ b/desktop/src-tauri/src/commands/agent_config_tests.rs @@ -122,6 +122,7 @@ fn agent_record() -> ManagedAgentRecord { auth_tag_ref: None, env_vars_ref: None, provider_config_ref: None, + secrets_unavailable: false, } } diff --git a/desktop/src-tauri/src/commands/agents.rs b/desktop/src-tauri/src/commands/agents.rs index 01da9f8e6c7..b54a2e59c34 100644 --- a/desktop/src-tauri/src/commands/agents.rs +++ b/desktop/src-tauri/src/commands/agents.rs @@ -916,6 +916,7 @@ pub async fn create_managed_agent( auth_tag_ref: None, env_vars_ref: None, provider_config_ref: None, + secrets_unavailable: false, };

Old-gen retirement moves entirely to two-cycle GC. Add 5 deterministic JSON-write-failure tests proving old generation still hydrates after a failed atomic write (instance env/auth/provider, definition env, global env). F5b (collect_live_refs validates): Reject malformed/duplicate coordinates and inline+ref conflicts — any such condition makes the sweep a no-op. Add 12 validation tests. F5a (GC exclusion, not just time): Wrap extraction + global save + GC under managed_agents_store_lock so final JSON read and remove_batch are indivisible against a concurrent save. Add 3 synchronized interleaving tests. F3 (fail-closed global + definition tiers): - Global: load_global_agent_config() returns Err on missing/corrupt ref; callers in runtime.rs/runtime_commands.rs now surface global_unavailable flag instead of unwrap_or_default(); spawn_agent_child uses ? to abort. - Definition: AgentDefinition gains secrets_unavailable field (#[serde(skip)]); hydrate_all_secrets_for_records sets it on definition records; spawn gate in runtime.rs refuses linked instances when definition is unavailable; status_for_with checks definition_unavailable tier; agents_deploy.rs checks it too. Add definition_tier_tests.rs with 3 tests. F4 (dev migration marker only on clean completion): Extract pure decision core plan_dev_secrets_migration(); marker withheld when conflict_count > 0; partial progress (non-conflicting keys) still written for next boot; log emitted. F2 (cleanup authorization + legacy live file): Replace bare agent_secret_store_pub().is_some() gate with extraction_verified() that reloads both stores and checks no secrets_unavailable flags set after hydration. Add scrub_legacy_live_file() to explicitly scrub/delete legacy managed-agents.json after verified extraction. Add 4 tests. AgentDefinition derives Default to support test helper construction.

F3: add require_effective_secrets_available — a single fail-closed gate (strict global loader, instance secrets_unavailable, linked-definition secrets_unavailable) consumed by every side-effecting path that was degrading silently: get_agent_models, mint_agent_card, the update_managed_agent rename, persona name/avatar propagation signing, and set_global_agent_config (which now refuses to overwrite a committed global whose ref cannot load rather than unwrap_or_default over it). F4: a dev-migration value conflict now writes a conflict: marker into the keyring blob. load_secret fails closed whenever a coordinate carries one, so hydration sets secrets_unavailable and every downstream gate refuses — making the conflicted value genuinely unavailable for the whole retry window instead of merely withholding the completion marker. A resolved conflict clears its marker. F5b: collect_live_refs now returns full expected blob coordinates alongside gen ids, and both GC sweeps no-op when any committed live reference is missing from the blob — so a dangling live ref can no longer let GC delete an older unreferenced generation that may be the only recoverable payload. F5a: add a cross-process transaction lock (a second advisory lockfile, distinct from the per-op mutate_blob lock) held from generation write through the JSON commit on every save path, and across the live-ref read through remove_batch in GC — closing the two-process interleave where one process could delete a generation another had written but not yet committed. Snapshot export: materialize_snapshot_bytes propagates the global loader Err instead of unwrap_or_default, refusing export/send rather than silently shipping empty inherited runtime/provider/model defaults. agent_models.rs, card.rs, and secret_store.rs are kept under the desktop file-size ratchet via #[path] sibling extraction (naming helpers, env-layer key resolution, and the secret_store test module respectively). Adds unit tests for the gate (all three tiers + precedence), conflict hydration→spawn-refusal, GC missing-coordinate freeze (both sweeps + positive bound), independent-participant txn-lock exclusion, and snapshot degradation refusal.

A disappearing source while the destination value is still live retains the marker (fail closed). - Cross-process transaction lock (Race 1): the lock now spans the other-half read through generation writes to the JSON commit in both save paths, so two Desktop processes cannot interleave a cross-half overwrite. Keyed by the symlink-resolved canonical store directory inode, not the keyring service, so processes sharing one JSON file always contend on one lock. - Transaction lockfile out of /tmp: the lock target is the store directory inode in the owner's app-data tree, immune to the tmp-cleaner unlink/recreate split that let two processes both "hold" a /tmp lockfile.

Merging current main pushed managed_agents/runtime.rs to 1012 split-count (>1000 limit): the PR's fail-closed spawn gating (+16) and main's mesh acp_model translation (+12) landed in disjoint regions of one file. Move the self-contained persona_drift_state helper verbatim to a new runtime/drift.rs sibling (the file's existing plain-submodule pattern) and re-export it, dropping runtime.rs to 986. No logic change: the fn body is identical; only visibility (pub(crate)) and an import replacing the inline fully-qualified type path differ.

And save_managed_agents re-read the definition half through the hydrating loader, so every instance-side save re-inlined definition secrets back into plaintext JSON and froze GC on the inline+ref conflict. Give the migration its own field-granular transition (migrate_inline_field -> FieldMigration) that only projects a non-empty inline value and never clears a ref it did not write; expose it as a pub(crate) seam so the custom-harness migration shares one W1-safe semantic. Re-read the definition half RAW under the txn lock and propagate a parse error with ? instead of unwrap_or_default(), so a malformed store fails the save rather than deleting every definition. Broaden the backup recognizer structurally to catch this repo's own pre-backfill.bak and pre-team-suffix-strip.bak producers.

Lift the log/receipt/PID domain (log-path resolution, rotation, install logs, runtime receipts, PID files, log-tail error extraction) into a storage/logs.rs submodule re-exported via `pub use logs::*`, and move its tests to storage/logs_tests.rs. Pure movement: each item keeps its original visibility so all caller paths resolve unchanged, and the workspace test count is identical before and after (2623 passed / 0 failed / 15 ignored).

Per-field cancel_gc_candidacy is dropped on this path: under the txn lock GC cannot run, a fresh UUID gen was never observed by a sweep, and a reused gen is a live ref sweeps skip, so no candidate marker can exist at save time. Verification bypasses the cache via verify_stored_raw so a backend that acks a write it did not persist is still caught.

Acquire the secret txn lock at the AppHandle-bearing entry points (import_identity, persist_current_identity, pairing recover), held across the persist span only. Lock order is identity_mutation -> txn -> blob on identity paths and txn -> blob on save/GC paths, so no path acquires them in opposing order. The boot path is left to single-instance serialization (lib.rs single-instance plugin).

Lift the self-contained databricks V1->V2 reconcile pair (reconcile_databricks_v1_to_v2 + its _in_file helper) into a migration/databricks_reconcile.rs submodule and move its tests to the sibling databricks_reconcile_tests.rs, reclaiming headroom. Pure movement: function bodies are byte-identical; only patch_json_records/canonical_dev_data_dir gain a super:: qualifier, the entry point narrows pub -> pub(super) (its sole caller is the boot call), and the test file's test_support import re-roots to crate::migration::test_support. All 11 databricks reconcile tests stay green.

Mirror the agent-store secret seam: add an `env_ref` generation pointer, strip `env` into the OS keyring under `harness::env:` on save, hydrate it back on load, and write the stripped JSON 0o600. A boot migration lifts pre-existing inline env, verifies each projected generation reads back, then scrubs plaintext-bearing backup/temp artifacts. Keyless builds and keyring outages keep env inline as an authoritative fallback.

Extract `unavailable_definition_id` next to its sibling `spawn_key_refusal` and route every site through it. It returns the offending definition id so the spawn and deploy paths can name it in the refusal message without a second lookup; status rows use `.is_some()`.

This makes the coverage and comments truthful at each: - global-config save and snapshot export each extract an AppHandle-free seam (refuse_save_on_unavailable_current, resolve_snapshot_global) so the missing/unreadable-ref refusal is unit-testable; both map only the Err arm and pass Ok through unchanged. - runtime_commands readiness tests drop two assertion-free let _ = status bodies for real local_setup assertions, with a positive control that proves the negatives are caused by the definition-unavailable gate. - a concurrent instance/definition save interleave test pins that neither half is lost or re-inlined under the shared txn lock; save_agent_ definitions_at is split out as the path-based seam it drives. - dev_service_migration, secret_store, and runtime comments corrected to match the code (marker-clear proof conditions, completion vs per- coordinate markers, Windows named mutex, lone degraded-empty consumer).

The lock primitive was proven; the production wiring was not (Thufir r5 IMPORTANT #1). Extract AppHandle-free entry points that own lock -> mutation as one unit: `save_managed_agents_locked_at`/`save_agent_definitions_locked_at` in storage, and `persist_identity_locked` (in commands/identity, the command-orchestration layer) for the three identity-persist sites. All production wrappers route through them. Identity persist contends on the same store-directory inode every agent save takes via `secret_txn_lock_dir`, so identity/agent secrets on the shared blob mutually exclude. The interleave tests now drive those exact seams via a store-injected barrier that pauses mid-mutation inside the lock span; a non-blocking flock(LOCK_NB) probe proves EWOULDBLOCK exclusion. Deleting either storage acquisition or the identity acquisition now turns the matching regression red.

Add a runtime-only env_unavailable marker (#[serde(skip)], reconstructed on load) mirroring the agent tier's secrets_unavailable. hydrate_harness_env sets it when a present env_ref cannot be resolved. Fail closed at all four harness seams — spawn, deploy, model discovery, and both status local_setup sites — via unavailable_harness_id. On save, persisted_unavailable_env_ref re-reads the on-disk record so an empty-env save over an unavailable record preserves the raw ref instead of clearing it; a genuine clear of a healthy record still clears. A rename of an unavailable record is refused: the ref key embeds the id, so it can neither be re-read under the new id nor carried forward safely. Also correct the harness_env_key comment: unreclaimed generations accrete (no harness-namespace GC), they are not bounded.

An unavailable secret tier hydrates to an empty env that is indistinguishable from an intentionally-empty one, so those flows could stop a live/setup process and only discover the refusal at respawn (FailedAfterStop). Add effective_secrets_unavailable(record, personas) — ORs the three registry-derivable tiers (instance secrets_unavailable, definition, harness) — and thread it through both eligibility predicates and the under-lock recheck in each flow, refusing before any stop.

Move the test module to a sibling agent_discovery_tests.rs included via #[path], matching the runtime_commands_tests.rs convention. Pure relocation, no behavior change.

charset=UTF-8 Content-Transfer-Encoding: 8bit The pass-2 secret-availability gate closed the stop-then-fail-at-respawn class for the record-derivable tiers (instance, definition, harness) but left two gaps: 1. Global tier: both post-install restart checks loaded the global config with unwrap_or_default() while spawn_agent_child reloads it strictly, so a restart authorized while the global ref was unavailable — even for an unrelated secret — would stop a live process only to hit the spawn refusal (FailedAfterStop). The global-config-save flow's under-lock recheck reused phase-1 snapshots and never re-attested the committed global ref before the stop. 2. The four production restart-gate call sites consulted effective_secrets_unavailable at the call site, so mutating any single call did not fail a test — only the pure predicate was bound. Add refuse_restart_on_unavailable_global (mirrors refuse_save_on_unavailable_current) and route the strict global load through it at both post-install sites and the global-config under-lock recheck. Consolidate each flow's secret consultation into AppHandle-free composed seams (should_restart_after_install_for, refuse_restart_on_unavailable_secrets, should_restart_on_config_change_for) so the consultation lives in one testable place, and bind each with record-driven regressions. Global availability stays a separate strict Result gate rather than a fourth arm of effective_secrets_unavailable — it is not derivable from a record.

A setup-mode agent could be stopped by an auto-restart while the committed global ref was unhydratable, then hit the strict global reload at spawn, refusing respawn after the live process was already stopped (FailedAfterStop). Extract the four restart flows into an AppHandle-free restart_ops module. Each op takes the global-config loader as a closure it invokes itself, so the strict-global re-read and load-before-stop ordering are op-owned and stop-spy-testable. The two pre-scan selectors own the strict-global gate (unreadable global yields zero candidates); the two under-lock authorizers re-read the committed global before the stop. Production shells in agent_discovery.rs and global_agent_config.rs become thin wiring.
