RBAC is baseline authorization, not the core innovation. A broadly + authorized action may still be warned or blocked because it is behaviorally + novel or has unusual downstream impact. +4. Keep these concepts distinct in code, storage, tests, and explanations: + declared capability, observed behavior, and historical behavioral baseline. +5. Previous trusted Run history must be able to affect the context or risk + decision for a future Run. +6. Important actions and decisions must generate persisted, structured Run + events. Diagnostic log strings are not a Run timeline. +7. A tripped circuit breaker must stop or pause the actual side effect. A badge, + toast, warning string, or post-hoc detection is not enforcement. +8. Delegation must preserve the originating user and Run, parent and child + Agent identities, delegation chain, and effective capability context. A + child must not gain privilege through delegation. +9. Reverse graph queries must be reusable backend middleware primitives, not + calculations available only to the frontend visualization. +10. User-facing explanations must use plain language and identify who tried to + do what, which resource was involved, why risk changed, and what the system + did. Raw JSON may be inspectable evidence but is not the primary UX. +11. Do not call static configuration, prompt claims, or fixed thresholds + "learning." Learning requires history-derived behavioral context that can + change a later decision. +12. Do not claim a capability works unless a relevant test exercised the real + path and the evidence is recorded. +13. Do not weaken, skip, delete, or rewrite tests merely to make implementation + appear successful. +14. Prefer a few deeply integrated, demonstrable capabilities over many + half-implemented signals or screens. +15. Changes from different agents must conform to the shared architecture + contracts. The Orchestrator owns contract changes and integration order. + +## Repository reality agents must preserve + +- The React/Vite frontend is under `apps/web`; the Fastify control plane and + runtime orchestration are under `apps/server`. +- `AgentService.sendMessage()` creates the Run. `AgentService.executeRun()` + invokes `applyRunPolicy()` before `runner.run()`. This is a genuine but coarse + whole-Run interception point. +- `ControlledActionRuntime` creates an attributable managed-action Run and + calls `ResourceGateway.request()`. The gateway resolves server-attested Run + identity, evaluates ownership/RBAC, exact capability, downstream graph + impact, trusted history, and breaker state, then atomically claims the exact + action before `SqliteManagedResourceAdapter.execute()` performs a durable + managed-state read or write. This narrow action-level path is real backend + middleware, not a frontend simulation. +- Once `CodexRunner` or `ContainerCodexRunner` starts, ordinary shell, + filesystem, connector, and network actions bypass `ResourceGateway`. The + managed SQLite adapter is the only production action adapter currently + proven through this boundary; never generalize that evidence to arbitrary + Codex tools. Parsing Codex JSON output is post-hoc observation and must not + be presented as a pre-effect gate. +- Agents, messages, and Runs are persisted in `launchpad.json`; graph, + observation, policy, approval, claim, timeline, identity, delegation, + behavioral-baseline, breaker, and managed-resource data are persisted in + `middleware.db`. SQLite is the authoritative store for security state. The + split still means SQLite records have service-validated weak Run references + rather than database foreign keys to `launchpad.json` Runs. +- The application resolves one configured authenticated principal for the + entire demo session. The shared bearer token authenticates the application, + not a distinct Alice or Bob login. Alice and Bob are deterministic graph + owners used to prove backend ownership enforcement; caller-supplied identity + fields or headers do not select the trusted principal. This is not a + multi-user, multi-tenant identity system or reviewer separation of duty. +- The backend graph now provides bounded deterministic forward and reverse + queries: exact capabilities, reachable resources, downstream impact, + inbound dependencies, affecting Agents, related Runs, ownership, and an + explainable Agent-to-Resource path. Runtime policy consumes downstream + impact. Durable delegation, ordered Run events, trusted-history baselines, + and a persistent `NORMAL`/`WARN`/`TRIPPED` breaker are implemented around + managed actions. +- The Run timeline supports persisted, sequence-ordered reconstruction of what + happened and why. It is not deterministic replay or re-execution of arbitrary + external side effects. External adapters still need an outbox and recovery + protocol for post-effect audit failure. +- Prompt and final-response observations are bounded text-derived claims, not + audited tool behavior. They may add Agent-scoped impact/risk context but + cannot grant a `CAN_*` capability or enter the trusted managed-action + baseline merely because the prompt asserted them. +- Existing generated `workspaces/*/AGENTS.md` files are runtime Agent data. + Never edit or treat them as repository engineering instructions. + +Do not erase these limitations from documentation until implementation and +tests prove they are resolved. + +## Engineering workflow + +The Orchestrator owns the build -> evaluate -> fix -> re-evaluate loop: + +1. Establish the clean baseline and freeze shared contracts. +2. Assign bounded, non-overlapping work to the appropriate specialist. +3. Specialists implement and return evidence; they do not self-certify. +4. The Orchestrator inspects code and runs focused checks. +5. The Integration agent exercises complete backend/runtime/data paths, + including actual side-effect prevention. +6. The Critic independently attempts to disprove the claims. +7. Every failure is routed to the specialist that owns the failing component. +8. Integration and Critic retest the fix. Repeat until every required criterion + passes or the Orchestrator reports a concrete blocker. + +Parallelize read-only exploration and truly disjoint edits. Shared agents use +one filesystem in the current environment, so the Orchestrator must assign file +ownership and sequence overlapping schema, domain-type, API-contract, and +lockfile changes. No agent may overwrite or discard another agent's work. + +## Repository conventions and evidence + +- Preserve ignored live state in `data/`, `apps/server/.data/`, `workspaces/`, + and `codex-home/`. Never expose `.env` or credential material. +- Add immutable numbered SQLite migrations; never edit an applied migration. + Preserve checksum verification, foreign keys, WAL behavior, validation, and + deterministic query ordering. +- Keep direct `CAN_*` edges explicit. Inferred graph proximity, observations, + ownership, past success, or delegation never grants authority. +- Security decisions fail closed when identity, policy, graph, baseline, event + persistence required for a decision, or breaker state cannot be resolved. +- Redact and bound event metadata before persistence. Never store secrets, + credential values, full environment data, or unconstrained tool output. +- Keep server and web DTOs synchronized; current duplicated Run types already + differ, so new contracts must not deepen that drift. +- The canonical repository check is `npm run check`. Also use focused Vitest + suites while iterating. Deployment-affecting work must validate + `docker compose config --quiet` and the relevant Docker/runtime path. +- Dependency work must audit production and development scopes, update the root + `package-lock.json`, and verify the built production tree. Never use a force + upgrade as a substitute for exploitability analysis. +- A passing unit test is not enough for an end-to-end claim. Tests must prove + the decision occurred before the real adapter effect and that blocked effects + did not happen. +- Report commands, outcomes, and unresolved risks accurately. If a required + tool such as Terraform is unavailable, state that limitation rather than + claiming validation. + +## Current execution gate + +The repository owner's final audit request explicitly opened the execution +phase for Tasks 2, 4, and 6. The Orchestrator may assign scoped implementation, +integration, and criticism work through the role loop above and may declare the +phase complete only through the release gate in +[`specs/acceptance-criteria.md`](specs/acceptance-criteria.md). + +Opening this execution phase is not standing authorization for unrelated work. +Future agents still require a current user request plus an Orchestrator-assigned +scope, must respect file ownership and destructive-action rules, and must not +weaken acceptance criteria or product invariants.

A shared bearer token authenticates access to +the demo application; it does not establish distinct Alice/Bob sessions. The +two named humans in the demo graph are deterministic ownership fixtures, and +caller-supplied user headers/body fields cannot replace the configured +principal. Do not describe this as production identity, tenancy, or reviewer +separation of duty. + +## Agent + +The existing `Agent` in `apps/server/src/types.ts` remains the lifecycle entity +with stable UUID, instructions, status, workspace, and Codex thread. Its graph +identity is `agent:{Agent UUID}`. An Agent node does not imply permission. + +The Agent service produces lifecycle state; graph provisioning maintains the +corresponding node. Delegation does not clone or mutate the Agent's declared +capabilities; it creates a separate effective execution context. + +## Run + +The existing `AgentRun` remains the user-visible execution aggregate and owns: + +- stable Run ID and Agent ID; +- status and lifecycle timestamps; +- prompt/final output/error/usage; +- policy summary/projection; +- originating identity and parent/delegation context when introduced. + +`AgentService` produces Runs. Policy, runner, timeline, API, and UI consume +them. Runs currently live in `launchpad.json`; agents must not assume a SQLite +foreign key until Runs are migrated. New SQLite security records must validate +the weak Run reference at the service boundary in the interim. + +## RunEvent + +`RunEvent` is an immutable, structured fact. Minimum conceptual fields: + +- stable event ID, schema version, Run ID, and strictly increasing Run-local + sequence; +- typed event name and wall-clock occurrence time; +- actor identity/effective principal context and Agent ID; +- optional delegation/parent/causation/correlation references; +- optional normalized action (`capability`, operation/tool name) and Resource; +- optional authorization/risk/breaker decision references and stable reason; +- outcome plus bounded, sanitized metadata safe for persistence and display. + +Run Timeline owns persistence and sequence allocation. Lifecycle, policy, +gateway, delegation, breaker, and runner components produce events at the point +of truth. Consumers always order by sequence; timestamps never resolve ties. +Events are append-only. Corrections are new events, not mutation of history. + +## Resource + +A Resource is the normalized target of an action, represented by a stable graph +`asset` node and an adapter-resolvable identifier.

A label match alone is not stable resource identity. + +## GraphNode and GraphEdge + +`apps/server/src/graph-types.ts` is the current canonical code contract. +Existing node types are `human`, `agent`, `asset`, `data_category`, and `run`. +Existing relations separate explicit authority (`CAN_*`), topology +(`DEPLOYS_TO`, `PROCESSES`, `CONTAINS`), accountability (`OWNS`), and audit +evidence (`ATTEMPTED`, `TOUCHED`, `DENIED`). + +Any new delegation/runtime relation requires coordinated updates to TypeScript +unions, validation, immutable migration, all store adapters, traversal rules, +tests, API DTOs, and UI projections. Authority rules: + +- only explicit, authorized direct capability plus effective delegation/RBAC + context can authorize an action; +- topology, reverse reachability, audit edges, observations, past success, and + ownership provide context but never authority; +- traversals are deterministic, bounded, cycle-safe, and return paths/factors; +- reverse queries are service-layer methods callable by policy, not client-only + graph transforms. + +## Delegation + +Delegation is a durable, revocable relationship for one origin/Run and bounded +scope. Required information: + +- delegation ID, origin human, origin Run; +- parent Agent/effective principal and child Agent; +- requested scope and computed effective capabilities/resources; +- parent delegation ID/depth where nested; +- status, creation, expiry/revocation, and reason/evidence. + +The delegation service produces it; identity resolution, authorization, graph, +events, baseline, and UX consume it. Effective child authority is the +intersection of origin authority, parent effective scope, explicit delegated +scope, and child capability. Delegation never creates authority outside that +intersection. + +## AuthorizationDecision + +Authorization is the baseline permission result for one resolved identity, +exact capability/action, Resource, and Run. Required information: + +- decision ID, Run, actor/effective principal, action/capability, target; +- `ALLOW` or `DENY`, stable reason code, matched authority/delegation evidence, + policy version, and creation time. + +RBAC/capability policy produces this decision. The risk evaluator, gateway, +events, and UX consume it. A DENY ends the pipeline before graph/baseline risk +can grant anything. An ALLOW permits risk evaluation; it is not an instruction +to execute. + +`PolicyDecisionRecord` remains the outward compatibility summary. The +integrated path persists linked `AuthorizationDecision` and `RiskDecision` +records, emits separate timeline facts, and exposes their evidence without +creating a second uncorrelated policy engine. + +## RiskDecision and CircuitBreakerDecision + +Risk evaluates an already-authorized action using graph context, trusted +behavioral history, sensitive-resource rules, and current breaker state. +Required information: + +- decision ID and linked AuthorizationDecision; +- `ALLOW`, `WARN`, or `BLOCK`; +- graph revision, baseline revision/history window, breaker state/version; +- deterministic factors with expected/observed values, contribution/threshold, + relevant paths/resources/Runs, reason code, and plain-English explanation; +- whether execution may proceed, requires approval/pause, or is prohibited. + +Compatibility mapping for the existing outward policy vocabulary is: +`ALLOW -> ALLOW`, `REVIEW_REQUIRED -> WARN` (paused until explicitly approved), +and `DENY -> BLOCK`. Do not collapse the distinct underlying decisions merely +to preserve these labels. + +The circuit breaker is persisted state scoped explicitly to an Agent, +delegation, Resource, or other documented boundary. Its `NORMAL`, `WARN`, and +`TRIPPED` transitions are atomic and produce Run events. `TRIPPED` prohibits +the covered effect until a defined recovery/reset condition succeeds. + +## BehavioralBaseline + +A baseline is a versioned aggregate of trusted prior mediated behavior, never a +static permission/configuration record. Required information: + +- baseline ID/revision, Agent/effective scope, calculation time/window; +- eligible source Run IDs and inclusion/exclusion policy; +- minimum-history/cold-start state; +- small deterministic statistics such as normal resources/actions, typical + resource count/blast radius, typical delegation depth, and denial history; +- poisoning controls, bounds, and update reason. + +The baseline builder consumes ordered RunEvents from eligible completed, +safe/accepted Runs. The risk evaluator consumes the frozen revision used for a +decision. Denied/blocked/failed/quarantined attempts can remain negative risk +evidence but cannot add their resources/actions to the trusted-normal set. +The current implementation aggregates only the latest 20 completed Runs, +selected by completion time and Run ID, and persists that window's limit, +count, start/end timestamps, and eligible source IDs. Changing this hard bound +requires an explicit architecture/test update; an unbounded scan is forbidden. + +## Required runtime ordering + +```text +Run / Agent action request + -> resolve identity and delegation context + -> baseline authorization (RBAC + exact capability) + -> query graph/reverse impact and blast radius + -> load frozen historical baseline and compare behavior + -> evaluate risk and persisted circuit-breaker state + -> persist decision and ordered event + -> if ALLOW (or approved WARN), atomically claim execution + -> execute exactly once through the authoritative ResourceAdapter + -> persist completion/failure event and eligible baseline evidence + +Any DENY, BLOCK, unapproved WARN, TRIPPED breaker, or required-context failure +returns before ResourceAdapter execution. +``` + +The adapter must not be callable through an unmediated alternate route. Post- +effect event parsing may enrich observation but cannot satisfy this ordering. + +For the current POC, this invariant has been proven only for resources marked +for `SqliteManagedResourceAdapter`. The adapter is constructed server-side and +is reachable by `ControlledActionRuntime` only through `ResourceGateway`. +`DemoResourceAdapter` remains test/legacy scaffolding and is not evidence of a +real effect. Ordinary Codex actions are outside this protected action boundary. + +The ordered event stream supports audit reconstruction: execution order, +origin and acting Agent, authorization and risk decisions, resources, +delegation, breaker transitions, failures, and final outcome. It does not +capture enough external state to promise deterministic replay or re-execution. +An external effect adapter requires a transactional outbox/idempotent +reconciliation design before equivalent post-effect recovery can be claimed. + +## Consistency and API rules + +- Security state belongs in `middleware.db` with immutable migrations and + atomic operations.

Start the development app and click **Create Agent**. Name it **Alice + Boundary Judge**, then open **Playground**. +2. Click **Grant private-record access**. The admin backend creates one exact + `CAN_READ` graph capability; Agent creation has already persisted + `human:alice -> OWNS -> agent:`. +3. Click **Verify resource boundary**. Alice's managed record completes through + the real SQLite adapter with the newly created Agent as actor. The same + Agent's attempt against Bob's record returns `DENY`, + the adapter is not called, and the Run timeline explains that Bob owns the + resource. Supplying `human:bob` in the body or a header does not change the + server-attested origin. +4. Click **Stop** and observe that another protected action returns `409` + without a claim or effect. Reload: Agent ownership, permission, status, and + Run evidence remain persisted. +5. Select **Release Guardian**, click **Verify resource boundary**, **Build + trusted baseline**, then **Request production update**. The exact write + permission is `ALLOW`, but downstream + customer-data impact plus historical novelty returns `BLOCK`; the durable + configuration remains unchanged. +6.

Follow +the card marked **Do this now**: grant exact access, verify the Alice/Bob +identity boundary, build trusted staging history, then test the broader +production change. Completed prerequisites turn green; locked steps always +state what must happen first. + +The result panel names the exact action and separates three questions: + +1. **Permission:** may this Agent access this resource? +2. **Safety:** is this permitted action acceptable in its current historical + and downstream-impact context? +3. **Resource:** did the protected adapter actually perform the effect? + +**Safety stop active** means the persistent circuit breaker is pausing all new +managed actions. Review the audit timeline before selecting **Reset safety +stop**. Resetting reopens evaluation; it does not approve the previous request, +and the same risky request may be blocked again.

Model-backed chat remains unavailable +until Ark is configured. + +To run the same proof as an isolated production-build browser test: + +```bash +npx playwright install chromium +npm run test:e2e +``` + +## Current middleware status and next work + +The repository now contains two complementary enforcement seams: + +1. A coarse pre-run graph policy can pause or deny Codex before it starts. +2. A stronger action-level `ResourceGateway` mediates managed resource effects. + It resolves the persisted Run identity, checks RBAC and exact capability, + calculates downstream impact, compares trusted historical behavior, records + an explainable `ALLOW`, `WARN`, or `BLOCK`, and creates a one-time execution + claim before the managed adapter can run. + +The selected-track gate is the Alice/Bob backend authorization boundary. The +central differentiation is deliberately beyond RBAC: after trusted staging +changes, Release Guardian has direct permission to change the shared deployment +configuration, but learned novelty plus sensitive downstream graph impact trips +the safety stop. The adapter remains unclaimed, the resource is unchanged, and +the ordered evidence survives reload and restart. + +Track B's required disable/update control is also enforced outside the UI: +operators or administrators may stop an Agent, after which protected actions +return before an execution claim or resource effect; only an administrator may +delete Agents or change graph permission/ownership facts. Every role check uses +the current durable principal record, so an earlier process-local role cannot +outlive a downgrade. + +The highest-value remaining work is: + +1. Route additional real tools through explicit protected adapters, or enforce + equivalent mediation in the Codex execution sandbox. Do not imply that + ordinary shell, filesystem, and network calls already use the gateway. +2. Replace the configured demo principal and shared bearer token with real + login/session identity, reviewer separation of duty, tenant boundaries, + rate limits, and CSRF protection. +3.
