Effective child +authority is always the positive intersection: + +`root grant ∩ parent ceiling ∩ role policy ∩ rollout policy ∩ workspace authority ∩ user grant ∩ remaining tree budget` + +- Unknown versions, roles, tools, grants, and fields fail closed. +- A descendant may only preserve or narrow its parent's effective authority. +- Workspace Full permission is an upper bound, not automatic child consent. +- A grant binds the tree, run, parent, chat, renderer owner, workspace identity + and revision, provider/model fingerprint, context revision, tool identities, + expiry, and resource budgets. +- One-shot approval binds the exact child tool-call ID, canonical argument + digest, and current authority revision. Replay, mutation, cancellation, + navigation, configuration drift, or cross-child use invalidates it. +- Privileged tools are built positively after authority resolution. Children do + not receive ambient parent tools, credentials, or the app process environment. + +### Data flow + +- Workspace read plus network egress is a combined exfiltration capability, not + two harmless independent grants. It needs explicit combined consent. +- MCP grants bind exact server IDs, connection fingerprints, tool names, schema + hashes, and effect classifications. Unknown tools are treated as mutating. +- Web and MCP credentials remain inside host-owned proxies and never enter child + context, snapshots, errors, or logs. +- Shell is presented as host-wide authority unless an enforceable OS sandbox + proves narrower filesystem, process, environment, and network boundaries. + +### Lifecycle + +- Root stop, chat deletion, workspace mutation, permission downgrade, authority + revocation, and app shutdown reach every managed descendant and active tool + call. Foreground arbitrary shell owns and drains one process group, but macOS + cannot guarantee recovery of a command that deliberately creates a new + session and daemonizes; exact approval and terminal state disclose this + exception and never claim full process-tree containment or rollback. +- Active and queued limits are global and bounded before any `Agent` is created. +- Tree budgets cover depth, launches, active/queued work, wall time, turns, tool + calls, tokens, output, and network operations and reserve atomically. +- Background initially means continuing while Aiden is open. App quit reconciles + unfinished work to `interrupted` unless a later phase proves a safe resumable + descriptor; it never implies that work survived quit. +- A detached run never waits invisibly for approval. Privileged background work + is approved before detachment or transitions visibly to `needs_attention` + without executing the effect. +- Execution success, effect completion, cancellation, and unknown-after-crash + remain distinct states. + +### Privacy and persistence + +- Forked context is an immutable, bounded projection of one exact persisted chat + revision. It excludes reasoning, signed thinking blocks, approval payloads, + orchestration/control messages, prior subagent calls/results, raw tool payloads, + secrets, and unsupported attachments. +- Renderer projections remain bounded, owner-checked, versioned, and sanitized. + Private manifests may contain hashes and fingerprints but never credentials. +- V1 exact parsers are not weakened. V2 uses a dispatcher and migration layer, + dual-reads V1/V2, writes V2 only after the migration gate, and preserves the + prior file when migration cannot be proven safe. + +## Model-facing contract direction + +The launch contract becomes explicit rather than inferring authority from a role: + +- `execution`: `foreground | background`; +- `context`: `fresh | fork`, defaulting to `fresh`; +- `capabilities`: positive requests for workspace read, workspace write, shell, + web, exact MCP server/tool scope, and delegation; +- `tasks`: role, label, task, and optional narrower capability/context choices; +- management actions: status, wait, stop, retry, and steer, each owner-checked and + bound to opaque run IDs. + +`fork` is selected when the user asks for it or the delegated task depends on +conversation decisions that cannot safely be restated. Reviewers and scouts stay +fresh by default. Failure to capture or sanitize the requested revision is an +explicit error; Aiden never silently substitutes fresh context. + +New writer/research roles are presentation defaults only. Role names never grant +authority. Capability resolution remains the sole authority boundary. + +## Runtime direction + +- Replace flat generation ownership with a tree authority object containing + `treeRootId`, `parentRunId`, `depth`, immutable ceilings, budgets, and one root + cancellation controller. +- Use depth `0` for the parent generation, `1` for direct children, and `2` for + one nested grandchild level. The first nesting release stops at depth `2`. +- Refactor concurrency so a parent waiting in its delegation tool does not hold + the only local/hosted execution lease needed by its descendant. Admission must + be inference-aware or hierarchically re-entrant without allowing parallel + siblings to bypass deployment limits. +- Persist private launch/effect manifests separately from renderer-safe snapshots. +- Preserve deterministic task ordering while allocating bounded result space + fairly to every child and every nested branch. + +## Delivery protocol + +Every phase follows the same mandatory loop: + +1. Implement only the phase scope and focused tests. +2. Run the phase's focused type, lint, unit, integration, UI, and package gates. +3.

Steering remains API-only until that same +coordinator owns delivery beyond the parent tool call. +The complete packaged/browser/accessibility journey remains the Phase 9 release +gate, while Phase 0 retains the existing packaged lifecycle smoke and contract +suite. + +## Phase 1 detailed work + +Completed 2026-08-05. Phase 1 shipped staged, production-inert V2 contracts and +cores for strict authority intersection, owner-bound approval, exact management, +foreground control, lossless V1 migration, canonical V2 storage, and rollback +dispatch. It intentionally added no privileged tools and did not expose dormant +feature switches. The full Subagents suite, type-check, lint, and diff checks +passed; independent storage and security reviews returned clean after correction +loops for crash ordering, manifest exactness, authority drift, capacity release, +mandatory stop fences, and transactional terminal admission. + +- Add a strict V2 request parser and a pure capability-intersection engine. +- Add lineage and authority revisions without exposing private IDs or fingerprints + to the renderer. +- Add a host-owned child `beforeToolCall` broker.

Phase 2 wires Stop after V2 authority, + persistence, and renderer ownership share one production lifecycle. Phase 7 + wires Retry through its app-lifetime coordinator; it is always a new run linked + to the prior terminal run and never reuses approval. +- Add states `needs_attention` and `stopped`; keep detachment as presentation, + not a terminal state. +- Add exact V1 adapters and V2 store fixtures. Rollback leaves V1 history readable + and ignores V2-only UI fields rather than deleting them. +- Add property/fuzz tests proving `effective child ⊆ parent ⊆ root`. + +## Phase 2 detailed work + +Completed 2026-08-05. Production now defaults to fail-closed canonical V2 with +an effective V1 rollback switch, immutable authority and capacity reservations +before launch, owner-bound durable Stop, and exact V1/V2 history projections. +Fork mode captures one persisted revision, positively projects and secret-scrubs +visible prose/validated attachments, clones independent sibling transcripts, +and compacts before the first provider request. The final aggregate gate passed +432 TypeScript tests, 8 native-store tests, 31 soak contracts, type-check, lint, +and diff checks; two independent reviews returned clean after race, rollback, +privacy, MIME, UI reachability, and partial-write correction loops. + +- Activate V2 authority, persistence, approval, and owner-bound management in + the production foreground path behind real rollback switches. No switch is + shipped while it has no production effect. +- V1 rollback rejects forked launches explicitly and never copies conversation + history while presenting a legacy fresh-context projection. +- Capture one persisted chat revision before launching parallel children. +- Convert only user-visible user/assistant prose into independent child message + arrays; attachments are copied only through existing validated bounded forms. +- Strip system/control/approval/subagent artifacts and every reasoning or signed + thinking block. +- Include the context mode and captured revision hash in the private launch + manifest and a safe `Fresh context`/`Forked conversation` label in the UI. +- Apply static-context capacity checks before provider I/O and normal compaction + before every subsequent child turn. + +## Phases 3–5: privileged foreground tools + +Phase 3 completed 2026-08-05. Foreground V2 children can now receive explicit, +independently rollbackable web and exact classified read-only MCP grants. The +host owns credentials, redirects, request/response ceilings, live authority, +shared network budgets, schema projection, effect-time approval, and credential +redaction. MCP discovery is deadline-bounded and credential-aware; authenticated +transports are remote-only and closed per operation. OAuth refresh races retain +every distinct transport-observed credential redactor behind process-keyed +deduplication and fail-closed ceilings. The final gate passed 508 scoped +TypeScript tests, 8 native-store tests, 4 isolated inventory tests, 31 soak +contracts, type-check, lint, and diff checks. Independent security and contract +reviews returned clean after the final credential-race and SSE-reconnect bounds +corrections. + +### Web + +- Move Exa execution behind a child-safe host proxy with `AbortSignal`, fixed + timeout, `redirect: "error"`, request/result byte ceilings, safe error text, + and no credential-bearing logs. +- Approve read-plus-egress when a query may contain workspace-derived content. + +### MCP + +- Resolve exact configured servers in main, bind connection fingerprints, tool + identities and schema hashes, and classify each tool as read-only or mutating. +- Unknown or changed tools fail as mutating and require a fresh exact approval. + +### Write/edit + +Phase 4 completed 2026-08-05. Foreground V2 children can now positively request +exact `write_file` and `edit_file` authority. Every call is inspected and pinned +descriptor-relatively by a dedicated universal native helper, converted into an +immutable effect digest, displayed in a structured owner-bound approval, and +committed once only if authority, workspace revision, arguments, target +revision, renderer ownership, and workspace-operation admission still match. +Replacement recovery remains attributable and crash-preserved until verified +finalization. Unsupported symlinks, hardlinks, special files, ACLs, flags, and +unknown xattrs fail closed; the ordinary macOS `com.apple.provenance` attribute +is the sole bounded metadata exception and is copied and verified exactly. + +The final gate passed 538 scoped TypeScript tests, 8 native run-store tests, 25 +native mutator tests, registered inventory/write/soak pretests, five repeated IO +stress runs (60/60), type-check, lint, and diff checks. Independent security and +contracts reviews returned clean after correction loops for recovery +durability/metadata, process leaks, replay and alias races, effective read-only +ceilings, lifecycle cleanup, renderer-safe display bounds, and truthful +fresh/fork/read/write prompt copy. Automatic per-child worktree creation remains +deferred to the background-effect authority and recovery design. + +- Do not reuse the current parent mutation path unchanged. Use pinned workspace + identity, no-follow validation, atomic verified replacement, expected-content + revisions, and conflict errors for concurrent children. +- Parent Full permission alone remains insufficient. +- Phase 4A adds a positive `workspaceWrite` request and an independent V2-only + rollback. Requested-but-unavailable write fails explicitly; it is never + silently downgraded to read-only. +- Phase 4B uses a dedicated main-owned native mutator for descriptor-relative + `openat` traversal, strict no-follow regular-file checks, expected SHA-256 + revisions, exclusive create, atomic swap replacement, verification, fsync, + and conflict/recovery preservation. Parent `fs.writeFile` tools are not reused. +- Phase 4C binds the prepared preimage/postimage effect digest to the exact + owner-bound one-shot approval and renders a structured create/replace/edit + approval. Deny retains initial focus; every mutation says that no command will + run and that drift makes Aiden refuse the write. +- Phase 4D runs the complete symlink, hardlink, special-file, sibling, external + race, cancellation, replay, crash-point, rollback, UI, and regression gates, + followed by two clean independent reviews. +- Automatic per-child worktree creation is deferred. Phase 4 writes only to the + exact current workspace; an already selected Aiden-managed worktree remains + eligible and is identified truthfully in approval. Automatic dedicated + worktrees require a separate authority, handoff/apply, cleanup, and recovery + lifecycle and remain part of the later background-effect design. + +### Shell + +Phase 5 was refrozen after three independent design lanes found that the prior +three shell bullets were insufficient for either arbitrary command execution or +remote mutations. Shell and mutating MCP have separate contracts, flags, +brokers, approval cards, and activation diffs. Every slice receives the normal +focused gate and two clean independent reviews before the next slice begins. + +#### 5A: shared revocation and durable effect foundation + +Completed 2026-08-05. The final correction gate passed 556 TypeScript Subagents +tests, 8 native run-store tests, 25 native file-mutator tests, all registered +inventory/write/Phase-5A/soak pretests, type-check, targeted lint, and diff +validation. The completed slice includes two-sided config/credential publication +fences; immediate connect/list/call leases; strict hostile-object parsing; +native-authority digest binding; dispatch-time expiry; crash/unknown semantics; +cross-store deletion preflight; and an owner-checked bounded external-effect +projection in the native inspector. + +- Add a main-owned per-server configuration epoch/abort lease. Accepted config, + endpoint, enablement, transport, credential-account, or OAuth reauthorization + changes synchronously invalidate the old lease before publication. The exact + lease is checked without an `await` immediately before raw MCP dispatch. Use + the same fence to close the existing read-lane disable/repoint TOCTOU; post-call + drift detection remains defense in depth. +- Activate the reserved private V2 `approvals` and `effects` collections using + strict exact parsers, identifier uniqueness, bounded cardinality, monotonic + transitions, run/chat ownership, and digest-only evidence. Raw commands, + arguments, responses, credentials, headers, and SDK errors are never durable. +- Persist an effect through + `prepared → authorized → dispatch_started → completed | remote_error | cancelled_before_dispatch | unknown`. + A durability barrier precedes process spawn or MCP request bytes. Startup maps + leftover `prepared`/`authorized` to `cancelled_before_dispatch` and leftover + `dispatch_started` to `unknown`; it never retries. A failed pre-dispatch + persistence barrier prevents dispatch. A failed post-dispatch terminal write + remains locally and visibly `unknown`. +- Project bounded sanitized effect activity and unknown outcomes through the + main-owned run snapshot/inspector path. Chat deletion removes matching terminal + evidence only through the existing durable tombstone lifecycle; active or + unknown evidence cannot be silently evicted for capacity. +- Move wrong-tool outbound approval mismatch through common ledger denial and + cleanup. This shared hardening is production-safe before mutation activation. + +#### 5B: mutating MCP contracts, classification, and approval + +Completed 2026-08-05 as a production-inert slice. The final gate passed the +104-test focused Phase-5B suite, the 563-test aggregate TypeScript Subagents +suite, 8 native run-store tests, 25 native file-mutator tests, all registered +inventory/write/Phase-5A/Phase-5B/soak pretests, type-check, targeted ESLint, +format validation, and diff validation. Mutation requests remain absent from +the model schema and production tool assembly; the independent mutation flag is +default-off and has no execution call site. + +- Add a separate optional positive `mcpMutations` request containing only logical + server/tool names. It is disjoint from read `mcp`, task requests can only + narrow their root lane, stale or unavailable requests fail explicitly, and + omission means no mutation authority. Fingerprints and effect metadata remain + main-private. +- Classify a tool as read-only only for a structurally valid explicit + `readOnlyHint: true`. Explicit false, absent, malformed, accessor/proxy, + conflicting, or unknown annotations enter the mutating inventory, never the + read lane. Destructive, idempotent, open-world, and task-support annotations + are untrusted display/profile hints; no hint reduces approval, proves rollback, + or enables retry. Required MCP task support remains unavailable. +- Bind authority to server ID, connection fingerprint, tool name, canonical + input/output schema hash, `read | mutating` classification, and a recomputed + effect-profile fingerprint. Capability intersection compares every field. +- Add strict `SubagentMcpMutationApprovalDetails` and a dedicated deny-first, + `Allow once` card. It shows the complete safely escaped canonical arguments, + exact logical target, digest prefixes, classification/profile, timeout, and + fixed copy that the configured server controls the effect, data outside Aiden + may change, rollback is unavailable, timeout/cancellation may be unknown, and + automatic retry is disabled. Malformed details remove Allow. +- Canonical arguments are plain bounded JSON, snapshotted before asynchronous + work, at most 64 KiB at execution and 8 KiB before safe display escaping. + Credential redaction changing the canonical arguments is a hard denial. + +#### 5C: mutating MCP execution and foreground activation + +Completed 2026-08-05. The exact fresh-client, two-inspection, durable +prepare/authorize/dispatch, synchronous final-fence, single raw-call, zero-retry, +bounded-result, conservative-unknown, and production foreground activation +contracts below are implemented. The registered Phase 5C suite passes 96 tests; +the aggregate subagent gate passes 567 TypeScript, 8 native-store, and 25 native +mutator tests. + +- Use a fresh isolated remote client per call; stdio MCP remains excluded because + it is process authority. Reinspect server, connection/account revision, schema, + classification, effect profile, and task support before and after owner + approval. The final synchronous fence checks signal, expiry, live authority, + config/credential lease, immutable binding, ledger, and network budget, marks + dispatch locally, then invokes the raw SDK without another `await`. +- Durably publish `authorized` and `dispatch_started` before raw call bytes. One + shared network-operation unit is charged at dispatch and never refunded. + Transport/auth retries are disabled. Server-declared idempotency never permits + automatic retry or crash replay. +- A valid response becomes `completed`/server-reported success or + `remote_error`/server-reported error; the latter warns that partial mutation + may still have occurred. Any post-dispatch timeout, abort, transport/protocol + failure, malformed or oversized response, credential/config/schema drift, or + terminal-persistence failure becomes `unknown`. Late responses cannot upgrade + unknown. A same-effect retry after unknown needs a fresh distinct approval + that explicitly calls out the prior unknown outcome. +- Bound raw transport, result parts, sanitized model-visible text, close/drain, + and all credential encodings. Prefix returned server data as untrusted and use + fixed mechanism-neutral errors. +- Activate only behind independent + `AIDEN_SUBAGENT_CHILD_MCP_MUTATIONS_ENABLED`, V2, foreground execution, base + MCP rollout, exact inventory, live owner approval, journal, and network budget. + Flag-off/V1/background/stdio paths expose no mutation schema or tool and stale + positive requests error instead of downgrading. + +#### 5D: production-inert native shell broker + +Completed 2026-08-05. The universal helper, framed host adapter, frozen empty +environment, canonical root binding, helper-side output caps, occupied-group +cleanup, explicit outcomes, adversarial limitation fixture, and release +build/sign/package verification are implemented without model schema, tool, +flag, UI, or runtime activation. + +- Do not reuse parent `run_command`. Build and package a dedicated signed + universal `aiden-subagent-shell-runner`. It opens the exact canonical workspace + root with `O_DIRECTORY | O_NOFOLLOW | O_CLOEXEC`, verifies approved device and + inode, then `fchdir`s before execution. Cwd is a proven initial directory, not + a filesystem sandbox. +- Execute the exact bounded command with fixed `/bin/zsh -f -c`, passing command + bytes over a framed pipe rather than argv/environment. Reject NUL, malformed + UTF-8, over-limit input, bidi controls, ESC/C1, CR/Unicode line separators, and + C0 controls other than LF/TAB without trimming or normalization. Command stdin + is `/dev/null`; there is no PTY. +- Construct environment from empty state with a fixed PATH, C locale, private + `0700` HOME/TMP/XDG directories, noninteractive Git/package-manager controls, + disabled askpass, and no copied host HOME, proxy, provider, OAuth, MCP, Aiden, + SSH-agent, cloud, package, Electron, Node, or dynamic-loader variables. This + prevents ambient inheritance only; it does not stop deliberate host access. +- Enforce 512 KiB each stdout/stderr before bytes reach Electron, bounded + head/tail model output, invalid-UTF-8 sanitization, timeout, closed file + descriptors, fixed protocol size, and a main watchdog. Raw command/output are + absent from argv, environment, logs, timeline, and durable state. +- Keep the helper as an occupied process-group member. Cancellation, timeout, + output flood, parent-control-pipe EOF, app shutdown, and normal direct-shell + exit send group TERM, wait one second, then group KILL and drain. A deliberately + daemonized new session can escape this boundary; the tests prove the limitation + rather than pretending containment. + +The 5D helper is supervision and ambient-authority reduction, not an OS sandbox. +Its adversarial `setsid`/double-fork fixture deliberately escapes the occupied +process group, proves that such a process survives group cleanup, and then +self-cleans the fixture process. Phase 5E approval copy must retain this limit. + +#### 5E: truthful shell contract and foreground activation + +Completed 2026-08-05. Positive root/task capability narrowing, independent +rollback and packaged-helper gates, exact attended approval, workspace/root +revalidation, durable one-shot dispatch, bounded untrusted output, cancellation +and unknown cleanup truth, production assembly/shutdown, and the structured +deny-first approval surface are active for V2 foreground children only. + +- Add optional positive root/task `shell`; omission is false and a task can only + preserve or narrow its root grant. The child-facing tool remains + `run_command { command }`, but it is assembled only for an effective V2 + foreground shell grant with live owner approval and packaged helper. +- Bind one-shot approval to exact command bytes, fixed shell/options, canonical + environment profile and ephemeral directories, root path/device/inode, + workspace and authority revisions, owner/tree/run/child/chat/tool-call IDs, + timeout/output ceilings, rollout revision, and expiry. Revalidate before and + after approval; consume once immediately before the durable dispatch boundary. +- Add strict `SubagentShellApprovalDetails`. Show the entire exact command in a + bounded scrollable block, exact initial cwd/shell/digests/limits/worktree, and + fixed copy: the command is not OS-sandboxed, has the macOS user's filesystem, + process, system-tool, Keychain/API, and network reach, is not rolled back, sends + output to the configured model, and deliberately detached processes may + survive cancellation. Malformed details remove Allow; Deny retains initial + focus and the only positive action is `Allow once`. +- Distinguish exited, signaled, timed out, output limited, cancelled, spawn or + protocol failure, and cleanup unconfirmed. Never describe timeout/cancellation + as rollback. If helper/group cleanup cannot be proved, return + `cleanup_unconfirmed`. Shell does not consume the web/MCP network counter + because one approved host command may perform unbounded network operations. +- Activate behind independent `AIDEN_SUBAGENT_CHILD_SHELL_ENABLED`. Disabled, + V1, background, permission-none, missing-approval, or missing-helper paths do + not evaluate the factory/broker and reject positive requests explicitly. + +#### 5F: aggregate adversarial and release gate + +Completed 2026-08-05. The registered Phase-5A through Phase-5E, inventory, +workspace-write, package/sign, soak, and repeated native-shell gates all passed. +The full Subagents aggregate passed 572 TypeScript tests plus 8 native store and +25 native mutator tests. The full repository gate passed 1,181 tests, 32 native +worktree-remover tests, and 41 Rust Computer Use broker tests with no failures. +Type-check, targeted lint/format, package parsing, and diff validation remained +clean. Per the run-specific user override, no further review subagents were +launched after the corrected Phase 5A gate. + +- MCP matrix: every annotation shape; config/endpoint/transport/account/schema/ + effect-profile drift at every boundary; execute-then-401/500; zero automatic + retries; timeout/abort/ignored abort; response and credential floods; crash at + every journal transition; startup no-replay reconciliation; prior-unknown + explicit retry; current read-lane revocation regression. +- Shell matrix: exhaustive ambient-secret corpus; rc/PATH/askpass resistance; + cwd replacement/symlink races; exact multiline/bidi approval; closed stdin/no + TTY; inherited-FD proof; infinite mixed output; invalid UTF-8; pipe-holding + grandchildren; TERM-ignoring jobs; successful leader with background jobs; + `setsid`/double-fork limitation fixture; parent SIGKILL/app quit; protocol and + helper crash points; zombie/FD/PGID reuse soak; missing/wrong packaged helper. +- Integration/UI: effective read-only ceiling, owner navigation, permission and + rollout downgrade, chat/workspace deletion, exact accessibility/focus, visible + unknown outcome, V1 and independent rollbacks, packaged Electron journey, + full Subagents/repository/type/lint/package gates, repeated process/IO soak, + and two clean independent reviews after every slice plus the aggregate diff. + +## Phase 6: nesting + +### Phase 6A: production-inert nesting core + +Completed 2026-08-06. Added an optional positive root/task `delegate` request +with omission false and task-narrow-only validation, while keeping the +production model schema, supervisor, persistence, renderer, and rollout surface +unchanged. The isolated core derives immutable main-session depth `0`, direct +child depth `1`, and nested child depth `2` identities, shares exact frozen +workspace/runtime/context ceilings, and permits only narrower capability and +tool ceilings. One tree-owned synchronous ledger now atomically accounts for +depth, launches, active/queued work, tokens, tool calls, wall time, and output. +Its scheduler reserves fan-out all-or-nothing and converts a waiting parent's +execution lease into a reserved resume slot, so local limit `1` and hosted limit +`2` descendants cannot deadlock. Root cancellation immediately settles public +work even when an active task ignores abort. The registered Phase 6A gate, +Subagents aggregate, type-check, targeted lint, and diff validation passed. + +### Phase 6B: production activation + +Completed 2026-08-06. An independent default-on/exact-zero rollback gate now +exposes the positive `delegate` schema only to eligible foreground V2 launches. +Only exact live depth-1 authorities receive a child-safe tool; fresh depth-2 +authorities persist `parentRunId`, revalidate their exact parent and workspace, +reject every capability escalation, and never receive delegation. +The production scheduler and runtime both yield parent capacity while awaiting +descendants, so local concurrency one cannot deadlock. Root cancellation, +deadline expiry, and telemetry budget exhaustion cancel the scheduler and +terminalize active plus queued nested runs. Fan-out reservation is synchronous +and all-or-nothing before projection. The registered Phase 6B gate, complete +Subagents aggregate, type-check, targeted lint/format/diff validation, and +package dry-run passed. + +Phase 6B defines one budget scope per generation-scoped supervisor/tree. Each +model `subagent` tool call gets a short-lived scheduler execution graph because +its exact immutable context/capability root can differ, while launches, tokens, +tool calls, output, and wall time are debited cumulatively across every call in +that generation. Repeated calls therefore cannot reset shared tree budgets. + +- Only tasks with the resolved `delegate` capability receive a child-safe + delegation tool. +- Descendants inherit the exact workspace/runtime/context ceiling and may request + only narrower capabilities. +- One tree owns all depth, launch, token, tool, wall-time, output, active, and + queued budgets. +- Scheduler tests must prove that local limit one and hosted limit two cannot + deadlock when parents wait for descendants. + +### Phase 6C: forked descendants and semantic inspector + +Completed 2026-08-06. A depth-1 child now captures an explicit nested `fork` +at the tool boundary before releasing its inference lease: only descriptor-safe +user-visible prose and validated user images enter a bounded immutable snapshot; +thinking, tool protocol, orchestration controls, secrets, private paths, and +later transcript mutations do not. Depth-2 receives that isolated capture once, +never rereads the parent, and still cannot delegate. + +The inspector now reconstructs only exact V2 parent lineage as a semantic +collapsible tree. Legacy, orphaned, and owner-mismatched records remain visible +roots. It has roving keyboard navigation, `treeitem` hierarchy metadata, +stable selection/focus across revisions, active-branch grouping, explicit +collapse with hidden-descendant counts, reduced-motion-safe transitions, and +the existing batched live announcements. A depth-1 Stop truthfully says +“Stop subtree”; a depth-2 Stop affects only that node. Retry remains absent +until Phase 7 can start a fresh app-lifetime run safely. + +Focused live-fork/tree/UI tests passed 90/90. The complete Subagents aggregate, +native helper gates, TypeScript, lint, and diff checks passed after updating the +former Phase 6B schema expectation that correctly changed when nested fork +became available. + +## Phases 7–8: background + +### Phase 7A: production-inert durable lifecycle core + +Completed 2026-08-06. A self-contained lifecycle core requires immutable fresh, +depth-1, workspace-read-only background authority and denies write, shell, web, +MCP, mutation, fork, and delegation. Acceptance is acknowledged only after an +atomic durable queued record. Revision-guarded compare-and-swap owns exact +owner/chat/workspace/revision management and every transition; bounded wait, +steering, and event ledgers cannot bypass required terminalization. Hooks run +only after durable intent, and ambiguous hook outcomes become `unknown`. +Startup reconciliation records active runs interrupted and never restarts them; +explicit stop, chat deletion, workspace revocation, and shutdown durably settle +matching work. No model schema or background executor is activated in 7A. + +### Phase 7B1: canonical lifecycle storage seam + +Completed 2026-08-06. Canonical V2 storage now owns a bounded private background +record beside its matching renderer-safe snapshot and native authority manifest. +Every compare-and-swap lifecycle write updates all three atomically; legacy V2 +files parse with an empty background collection. Startup reconciliation appends +the bounded interruption evidence to both representations, while chat deletion +removes the paired private record in the same tombstone transaction. The 40-test +focused lifecycle/store gate and TypeScript passed. Actual coordinator/schema +activation remains the next 7B slice. + +### Phase 7B2: app-lifetime coordinator core + +Completed 2026-08-06. The injected coordinator accepts durably before child +allocation, keeps a detached run after its parent returns, and owns unique +admission, terminal/timeout waits, safe-boundary steering acknowledgement, +owner stop, revocation, shutdown, and no-restart behavior. It remains isolated +from Electron, model schemas, and renderer exposure until production wiring. +Focused coordinator tests passed 3/3 with TypeScript clean. + +- Launch acknowledgement follows durable acceptance, not merely object creation. +- State machine: + `queued → starting → running ↔ needs_attention → completed | failed | timed_out | stopped | interrupted | unknown`. +- Chat switching and renderer navigation do not stop detached work. Chat deletion, + workspace revocation, explicit stop, and app shutdown do. +- Notifications supplement, never replace, persisted status. Selecting one deep + links to the exact tree node in the Subagents inspector. +- Initial background work is read-only. Privileged background work is launched + only after the foreground parent obtains an immutable preauthorization. +- Dedicated-worktree writes ship before background shell or mutating MCP. +- Automatic restart resume remains disabled until a later design proves safe + executable checkpoints, leases, idempotency, and authority revalidation. + +## Verification matrix + +Every final gate includes: + +- strict TypeScript and lint; +- all normal tests plus the complete `test:subagents` suite; +- V1/V2 parser, migration, rollback, and corruption fixtures; +- capability intersection, replay, expiry, drift, and revocation tests; +- context-window, secret corpus, prompt-injection, and exfiltration tests; +- process, filesystem, symlink, replacement, cancellation, and crash races; +- mounted production renderer components and accessibility-tree assertions; +- a real Electron journey for chips, tree, approvals, detach/navigation, + notification deep links, restart interruption, and history replay; +- short pull-request packaged smoke, longer nightly soak, and release soak; +- production dependency audit with subagent-reachable advisories triaged. + +## Alignment target + +After Phase 9, Aiden should align strongly with the valuable `pi-subagents` +semantics: foreground/background execution, fresh/fork context, nesting, bounded +tree status and controls, capability ceilings, and deterministic results. + +Aiden deliberately diverges where its desktop host can be safer: + +- unknown tools deny rather than allow; +- shell is an explicit high-risk capability rather than passed through; +- live approvals remain main-owned and renderer-owner-bound; +- credentials and private execution artifacts never enter child context; +- background privileged effects require durable preauthorization; +- the native inspector replaces Pi's Fleet TUI and filesystem status artifacts. diff --git a/main/handlers/chat-params.ts b/main/handlers/chat-params.ts index b87fe54..d3cc1b5 100644 --- a/main/handlers/chat-params.ts +++ b/main/handlers/chat-params.ts @@ -80,8 +80,8 @@ export function parseParams(value: unknown): ChatStartParams { if (p.thinkingLevel !== undefined && !isGenerationThinkingLevel(p.thinkingLevel)) { throw new Error("Invalid thinking level."); } - // "assistant-unattended" is deliberately not accepted here: only main may run - // the unattended prompt, which carries the [SILENT] contract. + // Background Assistant modes are deliberately not accepted here: only main + // may grant an unattended prompt or project-scoped automation capabilities. if (p.mode !== undefined && p.mode !== "assistant") throw new Error("Invalid chat mode."); const messages = p.messages.map((raw) => { const m = (typeof raw === "object" && raw !== null ?
