Dynamic choices require literal `enabled: true` and a nonblank `goal`; they are unavailable in headless/background supervision and can execute at most once per session. Actions require literal `enabled: true`, 1–10 items, session `maxActions` default 1/max 10, safe unique IDs, descriptions up to 500 characters, exactly one text input (1–2,000 characters, optional `submit`) or strict key array (1–32 keys), encoded bytes up to 4,096, cooldown 0–86,400,000 ms, and per-action executions 1–10. A code-owned process-wide cap permits at most 10 semantic action attempts across all sessions; refused or throwing writes consume an attempt, and the cap is not caller-configurable. +Quiet-state integration adds `quietIntervalMs`: one observe-only reassessment per inactivity episode (default 2,000ms, bounded 250–60,000 and still subject to `minIntervalMs`). It also covers sessions that produce no output. An unchanged quiet observation can notify but cannot execute fixed/dynamic actions or write terminal bytes. + `semanticPermissions` is also the explicit opt-in boundary for commands launched through `interactive_shell`. Omitting the field preserves existing launch behavior. Once present, each raw command or resolved structured-spawn command is matched exactly before PTY, session, process, or worktree creation. `deny` blocks, `ask` requires Pi's confirmation dialog, and `allow` proceeds; an empty array asks for every launch. Unavailable UI, rejection, or dialog failure blocks an `ask`. Query, input, attach, and lifecycle calls for existing sessions are unaffected. This is an `interactive_shell` launch policy, not a shell, Bash, Pi, or operating-system sandbox. ```json @@ -597,6 +599,8 @@ interactive_shell({ The extension conservatively extracts a fresh sequential numbered/lettered menu or an explicitly keyboard-navigable menu from the visible viewport. Wrapped descriptions and a single visible selection marker are supported; recognized navigation/cancel help, bounded visual separator chrome, and unsupported custom-input/chat rows may remain visible without becoming executable choices. This foreground-only feature can execute one dynamic choice per session. Jev receives a dedicated choice containing only code-owned opaque visible-option IDs plus `none`; it never receives or supplies terminal input, and dynamic options do not compete with configured actions or action controls. Code resolves the chosen ID to the exact extracted selector or navigation bytes. A two-option menu whose labels are `Yes`/`No`, or those words followed by a comma and qualifier (for example, `Yes, proceed`/`No, go back`), is code-classified as `dynamic-terminal-confirmation`; other supported menus use `dynamic-terminal-choice`. Inline prompts such as `(Y/n)`, free text, unsafe secret/lifecycle menus, ambiguous layouts, and other unsupported interactions produce no dynamic input. Global `jev.semanticPermissions` rules are the trusted policy source for each classification; project/tool configuration cannot add or weaken them. Prefer `ask` for both operation kinds unless a narrower trusted rule is intended. `deny` always blocks; `ask` opens Pi's confirmation dialog and grants one request bound to the session, operation, generation, and observation hash; `allow` skips the dialog. Elapsed/quiet time alone does not invalidate that hash, but terminal, session, or operation changes do. `stop_automation` prevents later and pending dynamic choices for the session. This is not general unattended CLI operation or a command sandbox. Existing configured fixed actions are unchanged and retain their ownership, freshness, secret, cooldown, dedupe, and budget gates. +Semantic events carry a bounded, source-grounded, already-redacted terminal excerpt and a content-sensitive `handoffIdentity`; the same unresolved state dedupes while a new same-type question wakes Pi. For an ordinary input handoff, Pi may send one `semanticReply` with that event's exact session, decision, generation, identity, and one bounded single-line response. Immediately before writing, runtime rechecks ownership, current observation, reload/takeover/exit state, secret state, response restrictions, and trusted global `semantic-reply` permission. Unmatched permission asks, deny wins, and unavailable UI fails closed. Ordinary manual `input` is unchanged. + Inspect semantic decisions with `interactive_shell({ semanticDecisions: true, semanticSessionId: sessionId })`. Inspect delivered events with `interactive_shell({ monitorEvents: true, monitorSessionId: sessionId })`; `monitorStatus: true` returns monitor lifecycle state. Optional diagnostics write private per-process JSONL journals under Pi's agent directory. Each process owns and bounds its own files, so writers need no shared lock. Records contain only fixed schema/version identifiers, random run and incident IDs, timestamps, bounded timing/token counts, fixed decision/event/outcome categories, and sanitized model names. They never contain terminal text, commands, paths, session IDs, observation hashes, configured goals or watches, credentials, API keys, raw provider responses, or free-form notes. Files are mode `0600`; expired records are excluded from summaries immediately, and old journals are pruned on later writes. Diagnostics add no terminal polling, provider request, notification, action, or automatic tuning. diff --git a/headless-monitor.ts b/headless-monitor.ts index 34f140f..cd47f81 100644 --- a/headless-monitor.ts +++ b/headless-monitor.ts @@ -7,6 +7,7 @@ import type { JevClient } from "./jev-client.ts"; import { SemanticSupervisor } from "./semantic-supervisor.ts"; import type { SemanticActionRegistry } from "./semantic-actions.ts"; import type { SemanticChoiceAuthorization } from "./semantic-choice-authorization.ts"; +import type { SemanticReplyBinding } from "./semantic-reply.ts"; export interface MonitorMatchInfo { strategy: MonitorStrategy; @@ -418,6 +419,9 @@ export class HeadlessDispatchMonitor { pauseSemantic(): void { this.semanticSupervisor?.pause(); } resumeSemantic(): void { this.semanticSupervisor?.resume(); } + submitSemanticReply(binding: SemanticReplyBinding, response: string, permissionAllowed: () => boolean): { ok: true } | { ok: false; reason: string } { + return this.semanticSupervisor?.submitReply(binding, response, permissionAllowed) ?? { ok: false, reason: "semantic-supervision-unavailable" }; + } rebindSemanticEpoch(isEpochCurrent: () => boolean): void { this.semanticSupervisor?.rebindEpoch(isEpochCurrent); } activateBackgroundLifecycle(options: { autoExitOnQuiet: boolean; timeout?: number; onComplete: (info: HeadlessCompletionInfo) => void }): void { diff --git a/index.ts b/index.ts index 1313c8d..18ba369 100644 --- a/index.ts +++ b/index.ts @@ -232,7 +232,7 @@ function compileSemanticRuntime(sessionId: string, mode: "hands-free" | "dispatc const diagnostics = jev.diagnostics?.enabled ? createSemanticDiagnosticsSession({ config: jev.diagnostics, sessionId, mode, model: jev.model }) : undefined; - let lastAttentionTriggerId: string | undefined; + let lastAttentionIdentity: string | undefined; return { ok: true as const, runtime: { @@ -245,16 +245,17 @@ function compileSemanticRuntime(sessionId: string, mode: "hands-free" | "dispatc const deliveries: SemanticDeliveryDiagnostic[] = []; for (const candidate of candidates) { if ((candidate.semantic?.kind === "attention" || candidate.semantic?.kind === "uncertain") - && candidate.triggerId === lastAttentionTriggerId) { + && (candidate.semantic.handoffIdentity ?? candidate.triggerId) === lastAttentionIdentity) { deliveries.push({ eventType: diagnosticEventType(candidate), outcome: "suppressed-unchanged" }); continue; } - const delivered = coordinator.getMonitor(sessionId)?.submitMonitorCandidate(candidate, `${recorded.generation}:${candidate.triggerId}`) === true; + const delivered = coordinator.getMonitor(sessionId)?.submitMonitorCandidate(candidate, candidate.semantic?.handoffIdentity ?? `${recorded.generation}:${candidate.triggerId}`) === true; deliveries.push({ eventType: diagnosticEventType(candidate), outcome: delivered ?

Model confidence is not authorization. Secret/credential/payment and process-lifecycle actions are forbidden; process exit remains PTY-owned. User takeover pauses semantics and fresh rendered output is required after control returns. In addition to per-action/session limits, a non-configurable process-wide cap allows 10 semantic action attempts across sessions; refused and throwing writes consume it. +`quietIntervalMs` performs exactly one observe-only reassessment per inactivity episode (default 2,000ms, bounded 250–60,000 and still gated by `minIntervalMs`), including no-output sessions. Quiet evaluation never writes bytes. + For a foreground hands-free/dispatch overlay, `semantic: { goal: "Select the stable release channel", dynamicChoices: { enabled: true } }` opts into at most one dynamic choice per session from fresh visible output. The extension—not Jev—extracts only sequential numbered/lettered or explicitly keyboard-navigable menus and binds opaque IDs to exact bytes. Wrapped descriptions, one visible marker, navigation/cancel help, bounded visual separator chrome, and non-executable custom-input/chat siblings are supported. Jev's dedicated dynamic choice contains only those opaque IDs plus `none`, separate from configured actions and controls. A two-option `Yes`/`No` menu, including comma-qualified labels such as `Yes, proceed`/`No, go back`, is code-owned `dynamic-terminal-confirmation`; other supported menus are `dynamic-terminal-choice`. Inline `(Y/n)`, free text, unsafe secret/lifecycle menus, ambiguous layouts, and unsupported formats produce no dynamic input. Global `jev.semanticPermissions` rules use `allow`, `ask`, or `deny`; deny wins, unmatched asks, and project/tool config cannot select or weaken operation identity. Prefer `ask` for both dynamic operation kinds unless a narrower trusted rule is intended. Ask uses Pi's one-time confirmation dialog bound to the exact session/operation/generation/hash; Pi owns delivery of that dialog. This feature is not general unattended CLI operation or a command sandbox. Configured fixed actions are unchanged and retain all existing gates. +Semantic event handoffs include a bounded redacted excerpt and content-sensitive identity. To answer an ordinary input handoff, one `semanticReply` must repeat the exact event session, decision, generation, and identity plus one bounded single-line response. Runtime freshness, ownership, secret/restriction, reload/takeover/exit, and trusted global `semantic-reply` permission checks happen immediately before the write; stale, denied, rejected, and UI-unavailable requests write nothing. This is not arbitrary command authority, and ordinary manual input is unchanged. + Query decisions with `{ semanticDecisions: true, semanticSessionId }`; query delivered events with `{ monitorEvents: true, monitorSessionId }`; query monitor state with `{ monitorStatus: true, monitorSessionId }`. Provider failure, uncertainty, staleness, or a visible final answer never means completion or permission. Optional global `jev.diagnostics` is a local, content-free flight recorder. It is off by default (`enabled: false`, 14-day retention, 20 MB per-process cap) and adds no terminal polling or model calls. Query its bounded summary with `{ semanticDiagnostics: true }`. It records only fixed categories, timing/token counts, versions, sanitized model names, and random run/incident IDs—never terminal text, commands, paths, session IDs, hashes, goals, watch conditions, credentials, raw responses, or notes.
