Actor v2 stage V2-9: durable runs — checkpoints, resume, fork, compare (#204)

OP OpenVibers committed 14 days ago · 75e55e7986 · 39 files, +2501 −87

* Checkpoints after every step, resume after a restart, fork from any step, compare two runs

Actor v2 stage V2-9. A checkpoint after every loop step is sealed with AES-256-GCM under a new ACTOR_CHECKPOINT_KEY (AAD checkpoint|task|step), bound to its task and step, stripped of credentials and tool results marked secret, and pruned to the last 50 per task; without the key nothing is written.

On boot an open task resumes from its newest checkpoint, at most twice, then fails with 'interrupted twice'. A resume never re-runs a tool call the checkpoint already holds, and shows a span and a 'Picked up after a restart at step N' event. A finished run's saved steps each offer 'Fork from here': a new task with parent_id and fork_of_step that starts from that checkpoint with one change (another tier, one tool removed, or an edited instruction), its own budget and the parent's allow-list at most. /tasks/:id/compare/:otherId shows two of the person's runs side by side (answers, cost, time, steps, differing claims), stacked behind Answer/Steps/Cost chips on a phone, and links a run's Bench offer. Fork, compare and the fork dialog are owner-only; the fork POST is same-origin.

Migration 0021 adds actor_checkpoints (task_id FK ON DELETE CASCADE, step, created_at, state_enc) and nullable tasks.fork_of_step, tasks.fork_change and tasks.resumes. Checkpoints are exported as step metadata and erased with the person. Tests cover sealing and AAD, off without the key, a checkpoint per step, a simulated crash and resume without a tool re-run, the resume cap, forks with a tier change / an edited step / a removed tool and their allow-list, the compare owner check, pruning, and account data.

* Resume never repeats an acting tool: an intent before it, a card after a crash

A tool module now says acts: true when it changes something outside the model's own reasoning. The 12 are codes_task, computer_browser, computer_desk, computer_input, computer_run, computer_write, hand_to_person, make_chart, make_file, remember, robot_steps and run_tool (which may run any OpenVibe.Tools tool); every other tool is read-only and unmarked. test/tool-acts.test.js lists the whole registry so a new tool has to decide.

Before a batch with an acting call the loop writes each call's id, tool and input into the state's acting list and checkpoints it; the normal checkpoint after the results clears it. On resume a pending acting call is never run automatically: the task goes to needs_you with 'Actor was stopped mid-action' and the three choices. Run it again deliberately runs it once; It happened, go on records a person-confirmed result as evidence and runs nothing; Stop the task ends it cancelled. All calls of the same assistant turn are answered, so read-only calls that shared it are re-run and the conversation stays valid. An input whose secret was stripped cannot be run again from the checkpoint; the card says so. A secret-shaped acting input is summarised through stripSecrets and redactText, so the card has no secrets.

Sub-agents are never offered an acting tool (they have no checkpoint of their own); the parent is the one that acts. The fork dialog lists the acting tools used after the fork point, and a step stopped mid-action cannot be forked. The acting card's answer form is the existing owner-only, same-origin /tasks/:id/answer route.

Tests: test/durable-acting.test.js crashes inside a fake robot_steps and checks the card and no re-run, each of the three choices, a read-only crash re-run, and the fork list. OV_ALLOW_SUITE=1 npm test: 81/81 files. Shots: the acting card at 390/1280 dark/light in research-2026-10-30/actor-v2-9-shots/.

* Close the task's desks when a resume's acting card fails before the drive

resolveActing() runs before drive(), so a throw from the card (cancelled, unresolved, a fork of a mid-action step) has to go through the same close() as the drive. The pre-drive block is now in its own try/finally-style catch that closes the desks and rethrows.

++-- phase: expand
++-- Actor v2, stage V2-9: a sealed checkpoint after every model step, so a run picks up after a restart, and any step can
++-- be replayed or forked with one change.
++--
++-- state_enc is the loop's own state (messages, the ledgers, the evidence, the allow-list, the budget spent and the
++-- tier) as JSON, sealed with AES-256-GCM under ACTOR_CHECKPOINT_KEY and bound to its task and step
++-- (server/runtime/checkpoints.js). Nothing is stored in cleartext, and no secret or tool credential is ever inside:
++-- server/runtime/checkpoints.js strips them before sealing.
++--
++-- The last 50 rows per task are kept (pruned after every write). A row goes with its task (ON DELETE CASCADE) and is
++-- exported and erased with the person (server/identity/account-data.js). Additive only: a new table and three new
++-- nullable task columns. An older release that does not know them ignores them.
++CREATE TABLE actor_checkpoints (
++ task_id text COLLATE "C" NOT NULL REFERENCES tasks (id) ON DELETE CASCADE,
++ step integer NOT NULL CHECK (step >= 0),
++ created_at text COLLATE "C" NOT NULL,
++ state_enc text NOT NULL,
++ PRIMARY KEY (task_id, step)
++);
++CREATE INDEX actor_checkpoints_task_step ON actor_checkpoints (task_id, step DESC);
++
++-- A fork is a new task that starts from its parent's checkpoint at fork_of_step (parent_id is the parent, as a
++-- follow-up already is); fork_change records the one change the person picked, so the page and the compare page can
++-- say it. A resumed run counts its resumes, so the third interruption fails it instead of looping forever.

++/**
++ * Sealed checkpoints (Actor v2, stage V2-9): one after every step, so a run can pick up after a restart, and any
++ * step can be forked with one change.
++ *
++ * Encryption is the same pattern as OpenVibe.AI's person credentials (server/credentials.js): AES-256-GCM with a
++ * random 12-byte IV and the tag stored beside the body, under ACTOR_CHECKPOINT_KEY (64 hex characters). The additional
++ * authenticated data binds a row to its task and step (`checkpoint|<task_id>|<step>`), so a ciphertext moved to
++ * another task or step does not open. Without a valid key, checkpoints are off: save() writes nothing, at() and
++ * last() answer null, and the task behaves as it did before this stage.
++ *
++ * Nothing in a checkpoint is a secret or a tool credential: stripSecrets() removes any value under a credential-shaped
++ * key, any common token shape, and any tool result a tool marked `secret: true`. It runs before sealing, so even a
++ * database reader with the key cannot recover what a tool marked secret.
++ *
++ * createCheckpoints({ store, config, log, now }) → {
++ * enabled, seal(plain, aad), open(sealed, aad), aad(taskId, step),
++ * save({ taskId, step, state }), at(taskId, step), last(taskId), list(taskId), prune(taskId), count(taskId)
++ * }
++ *
++ * The last `config.checkpoints.keep` rows per task are kept (50 by default); a row goes with its task (ON DELETE
++ * CASCADE) and is exported and erased with the person.

++ * 3. the two runs are compared: answers, cost, time, steps and the claims that differ.
++ *
++ * It boots Actor as the service does, with the real provider keys from the environment, but with a fresh PGlite
++ * database in /tmp (DATABASE_URL is cleared, NODE_ENV is development) and a fresh ACTOR_CHECKPOINT_KEY generated for
++ * this process only. Nothing touches production data. The key is never printed.
