Distillation

Current State

• Date: Sep 15, 2026. A frozen, strictly read-only adversarial correctness review is still in progress for the complete V2 interrupted-session recovery candidate in /home/byk/Code/opencode. No files may be edited, no formatters/tests/services may be run if they mutate state, Git must not be changed, production data must not be touched, and Lore recall was prohibited for this review.
• Immutable review coordinates:
  • Base commit: ab9408c81cc9916177641ae8e9f08624fc27b5b9
  • Committed HEAD: dc661f30cb2055ad6248fdc59b14998d834497be
  • Candidate: HEAD plus frozen uncommitted validation delta
  • Canonical patch: /tmp/opencode/session-recovery-full.patch
  • Canonical patch SHA-256: f051a53df476dd924bda0a14c4cd91a63c9e7eafff53bbe71f0460571335fcbd
  • SEA: packages/opencode/dist/server/opencode-server
  • SEA SHA-256: 1ecc9afe36c12b31a8892cdbfb8a1560ceec97255c3537c073b795351233be40
• The patch temporarily disappeared after a server restart at 06:07–06:08 (sha256sum: /tmp/opencode/session-recovery-full.patch: No such file or directory; search returned No files found), but it was restored and verified at 07:47 and again at 12:35. Both Git revisions resolve as commit objects, and HEAD remains dc661f30cb2055ad6248fdc59b14998d834497be. The review is therefore no longer blocked by missing evidence.
• The required final deliverable has not yet been emitted. It must:
  • Be substantive and non-empty.
  • Classify findings as PASS, CONCERN, or MUST-FIX.
  • Cite exact current file:line evidence.
  • Cover all 24 files in the canonical patch.
  • End with a final line containing exactly MERGE or DO-NOT-MERGE.
  • If blocked, quote the exact command/error, identify affected scope, and end DO-NOT-MERGE.
  • Never return a context warning, separator, progress-only note, or empty output.
• Review focus remains: durable lease acquisition/takeover/fencing; heartbeat/expiry races; explicit interruption and scope shutdown; recovery atomicity/idempotence/replay; latest-assistant supersession; ready/safe/unknown semantics; provider and local/hosted tool ambiguity; overflow compaction; pending inbox behavior; startup composition; fresh and upgraded migrations; regression quality.
• Likely unresolved merge blockers discovered during inspection:
  1. Upgraded-database migration failure: packages/core/src/database/migration/20260914235657_session-execution-lease.ts directly executes ALTER TABLE \session_execution` ADD `expires_at` integer NOT NULL;. SQLite rejects adding a required column without a default when an upgraded database already has session_executionrows. Required sequence is nullable/defaulted add, explicit backfill policy, then optional table rebuild to enforceNOT NULL`.
  2. Cluster lease/epoch fencing appears incomplete: acquisition uses a unique execution ID and owner ID, but renewal and inspected ownership checks do not consistently require an unexpired lease/fencing epoch at every provider/tool dispatch, event commit, phase transition, and context mutation. Repository guidance explicitly says claim IDs and owner IDs alone are insufficient after expiry/takeover.
  3. Coordinator interrupt/wake race: packages/core/src/session/run-coordinator.ts:81-101 allows wake() to set pendingWake = true after interrupt() has set stopping = true and cleared it, potentially scheduling a successor during shutdown.
• The review must remain frozen until correctness and security reviews pass. Unresolved lifecycle/integrity findings prohibit merge, publish, or active-server reload; after fixes, validations and fresh approvals are required before one controlled reload.
• Previously reported validation supplied by the user: Core typecheck; schema/server/opencode typechecks; 112 focused tests; full Core suite with 1108 tests; migration check; recorded cassette replay; Node and SEA builds; isolated authenticated health, migration, and SIGTERM smoke tests. New regressions reportedly failed on base dc661f30cb2055ad6248fdc59b14998d834497be with exactly 6 failures across focused ownership/recovery files and passed on the candidate. These are user-supplied results, not rerun during the frozen review.
• Repository workflow constraints remain active for future work:
  • Typecheck via bun typecheck from the relevant package directory; never invoke tsc directly.
  • Never run package tests from repository root because of do-not-run-tests-from-root; use directories such as packages/opencode.
  • For Effect work, inspect current Effect v4 / effect-smol source and nearby repository patterns first. If .opencode/references/effect-smol is absent, clone https://github.com/Effect-TS/effect-smol there, not into a skill directory.
  • Follow local AGENTS.md, .lore.md, generated-file workflows, architecture/import direction, and package-specific commands.

Key Decisions

• The canonical patch, not the mutable working tree, is the immutable review scope. Current files are only for exact line-number evidence.
• Core invariants established by the user:
  • Never call legacy SessionPrompt / SessionPrompt.loop(...).
  • Exactly one explicit llm.stream(request) per physical provider attempt.
  • Never silently re-execute old or uncertain provider/tool calls.
  • Uncertain provider/tool outcomes become model-visible unknown errors.
  • Never recover or resume an older assistant projection; the newest assistant row is authoritative even if it is completed.
  • Never recover a live execution lease.
  • Never recover an execution superseded by a newer assistant.
  • Never start a second owner while a lease is live.
  • Never re-enter the same owner’s uncertain live lease.
  • EventV2 replay ownership remains separate from Session execution ownership.
  • Core never imports Server.
  • Local ownership must be replaced by durable multi-node ownership in clustered deployments.
• Prompt admission and execution remain separate:
  • SessionV2.prompt(...) first durably admits one session_input, then schedules advisory SessionExecution.wake(sessionID) unless resume: false.
  • Reusing a Session ID adopts the Session.
  • Reusing a prompt message ID is an exact retry only when Session, prompt, and delivery match; conflicting reuse fails.
  • Default delivery is "steer"; steers promote at the next safe provider boundary, while explicit "queue" remains pending until otherwise idle.
• Session execution architecture:
  • SessionExecution remains process-global and Session-ID based.
  • SessionRunCoordinator joins explicit same-Session resumes, coalesces prompt wakes, and allows different Sessions concurrently.
  • Location-scoped runner/model/tools/permissions/filesystem are resolved only when a drain starts via SessionStore and LocationServiceMap.get(session.location).
  • Omitted Location.workspaceID means implicit-local; explicit workspace identity is reserved for future placement.
• Durable cluster safety requirement:
  • Use leases plus a fencing token/epoch and unique execution IDs.
  • Acquisition, renewal, phase transition, context update, provider/tool dispatch, and event commit must verify token, require an unexpired lease, and affect exactly one row.
  • Only expired claims may be replaced.
  • Lifecycle mutations must be atomic with durable event commits.
  • Claim/owner IDs by themselves were explicitly rejected because stale runners can mutate or renew after takeover and same-owner re-entry can overwrite a live claim.
• Recovery policy:
  • Expired/uncertain work must be reconciled before waking pending inputs.
  • "safe" claims are disposable without recovery.
  • "ready" and "unknown" recovery produce explicit continuation/information rather than replaying uncertain effects.
  • Superseded claims are deleted without recovery.
  • Replayable projectors remain separate from local operational ownership.
• Effect implementation conventions:
  • Use Effect.gen(function* () { ... }) for multi-step workflows.
  • Use Effect.fn("Name") or Effect.fnUntraced(...) for reusable service methods/important workflows.
  • Prefer Effect Schema, branded schemas, and Schema.TaggedErrorClass.
  • Keep HTTP handlers thin and layers explicit.
  • Do not introduce any, non-null assertions, unchecked casts, or old Effect APIs merely to satisfy types.
  • Use testEffect(...) from packages/opencode/test/lib/effect.ts for Effect services/layers/runtime/scopes; use it.live(...) for filesystem, Git, HTTP, sockets, processes, locks, and real time; use explicit layers and scoped fixture finalizers.
• Compaction decision:
  • Persist a durable summary boundary and reload projected history for continuation.
  • Avoid an in-memory tool loop.
  • Overflow recovery permits only one rebuilt attempt before durable output or side effects.
• Startup decision:
  • SessionRecovery.node must be composed into both hosted/server and local opencode application graphs with SessionExecution.node substituted by SessionExecutionLocal.node.
  • Layer.provideMerge(Observability.layer) must remain last in the opencode HTTP server graph so eager fibers inherit the configured logger rather than corrupting the TUI (#34730).
• Plugin teardown rule from .lore.md:225: update inventory and release activation-lock ownership before asynchronously closing scopes; never join disabled-plugin finalizers while holding activation/readiness locks; always release the readiness token even if cleanup/reporting fails.
• Legacy V1 durability rationale: transcript events and SQL projections are durable, but run state, busy/retry status, permissions, background jobs, and ownership are in memory. Automatic restart replay was rejected because there was no startup recovery scan or durable attempt boundary, making provider/tool effects uncertain and allowing concurrent execution.

• Schema and migrations

  • packages/core/src/session/sql.ts:140-166 defines SessionInputTable with id, session_id, JSON prompt, delivery, admitted_seq, nullable promoted_seq, and time_created; indexes:
    • session_input_session_pending_delivery_seq_idx
    • unique session_input_session_admitted_seq_idx
    • unique session_input_session_promoted_seq_idx
  • packages/core/src/session/sql.ts:168-191 defines SessionRecoveryTable with session_id, execution_id, non-null assistant_message_id, continuation_message_id, and time_created; composite PK (session_id, assistant_message_id); unique indexes session_recovery_execution_idx and session_recovery_continuation_message_idx.
  • packages/core/src/session/sql.ts:193-211 defines SessionExecutionTable with id, unique session_id, owner_id, nullable assistant_message_id, phase "ready" | "safe" | "unknown", time_created, and expires_at; indexes session_execution_session_idx and session_execution_owner_idx.
  • packages/core/src/session/sql.ts:213 sets SESSION_EXECUTION_LEASE_MS = 30_000.
  • 20260914170650_session-recovery creates the original recovery table, cascade foreign keys, composite PK, and unique continuation index.
  • 20260914214636_session-execution creates execution ownership, adds non-null execution_id to recovery, and adds execution/session/owner indexes.
  • 20260914222526_session-execution-phase.ts:1-11 runs ALTER TABLE \session_execution` ADD `phase` text NOT NULL;`.
  • 20260914235657_session-execution-lease.ts runs ALTER TABLE \session_execution` ADD `expires_at` integer NOT NULL;`; this is the identified upgraded-database migration trap.
  • Current generated schema inspection at 12:53–13:01 showed all four migrations and both tables represented, though a later 13:42 inspection of a different/current snapshot reported migration.gen.ts with only 38 old imports and omitted September migrations. The immutable patch is authoritative; generated registry consistency must be judged from it, not transient working-tree snapshots.
  • Fresh-database migration behavior in packages/core/src/database/migration.ts:11-106: serialized via Semaphore.makeUnsafe(1); empty DB installs generated schema and journals all migrations atomically; upgraded DB applies missing migrations transactionally one at a time; legacy Drizzle journals are mapped by name or timestamp, with unmatched timestamps defecting as Legacy migration timestamp ${entry.created_at} does not match any known migration.
  • packages/core/test/database-migration.test.ts checks the migration generator with a 30,000 ms Linux timeout and expects "No schema changes, nothing to migrate"; fresh-DB tests inspect key tables, removed transitional columns, migration count, and expected indexes.

• Lease acquisition, takeover, renewal, and interruption

  • packages/core/src/session/execution/local.ts creates one process ownerID via crypto.randomUUID() and computes lease duration from SESSION_EXECUTION_LEASE_MS.
  • Every drain generates a new executionID and attempts to insert phase "ready" with no assistant, creation time, and expiry.
  • Conflict on session_id replaces a claim only when:
    1. Same ownerID and existing phase is "ready" or "safe", or
    2. Existing expires_at < Date.now().
  • Takeover resets ID, owner, phase, assistant, creation time, and expiry.
  • No returned row means the drain exits before calling input.run, preventing a second live owner.
  • renew(executionID) updates expiry only where id and owner_id match; no returned row dies with Session execution claim lost: ${executionID}.
  • Claimed work races input.run(sessionID, force, executionID) against renewal repeated every 10 seconds using Effect.raceFirst; Effect v4 source at Effect.ts:4847-4901 confirms raceFirst returns first completion, success or failure, and interrupts the loser.
  • Exact-claim cleanup occurs only after successful drain completion. Failed/interrupted drains retain claims for lease handling. Non-interruption failure logs Failed to drain Session.
  • interrupt(sessionID) interrupts the coordinator and then deletes claims matching Session plus current process owner.
  • The execution layer loads the Session, dies with Session not found: ${sessionID} if absent, resolves location, and invokes runner.run({ sessionID, force, executionID }).
  • SessionExecutionLocal.node uses dependencies [Database.node, SessionStore.node, LocationServiceMap.node].
  • Potential correctness gap: renew/update checks based only on execution ID and owner do not visibly enforce expires_at >= now or a monotonically changing fencing epoch, contrary to cluster requirements.

• Run coordinator

  • packages/core/src/session/run-coordinator.ts:5-22 provides keyed active, run, wake, and interrupt; entries track done, optional owner, pendingWake, and stopping.
  • :37-79 starts fibers through a FiberSet, joins existing explicit runs, retries after stopping entries, and starts a forced drain when idle.
  • :51-65 coalesces one successful follow-up and may install a successor before completing the old done.
  • :81-92 lets wake() set pendingWake = true on any existing entry without checking stopping.
  • :94-101 has interrupt() set stopping = true, clear pendingWake, and interrupt the owner. A concurrent later wake can restore pendingWake, creating a shutdown race.

• Recovery

  • packages/core/src/session/recovery.ts scans only claims with expires_at < Date.now().
  • It queries the latest assistant for the Session by descending message sequence.
  • "safe" claims and claims whose owned assistant has been superseded are deleted without recovery; deletion rechecks expiration.
  • Recoverable claims reuse their assistant ID as recoveryMessageID when present, otherwise generate a new message ID; continuation always gets a fresh ID.
  • SessionEvent.Step.Recovered contains Session, timestamp, execution ID, recovery message ID, optional assistant ID, continuation ID, and phase.
  • The event commit hook atomically deletes the exact expired claim, matching ID, Session, phase, nullable assistant state, and expiry condition; mismatch defects with Recovery execution claim changed: ${claim.id}.
  • Duplicate publication is accepted only if SessionRecoveryTable already contains matching (session_id, execution_id); other defects are rethrown.
  • execution.wake(claim.session_id) occurs only after a newly published recovery (packages/core/src/session/recovery.ts:102), not after duplicate detection.
  • The recovery loop repeats every 10 seconds, logs Failed to recover Sessions, forks scoped, and depends on [Database.node, EventV2.node, SessionProjector.node, SessionExecution.node].

• Projection and latest-assistant safety

  • packages/core/src/session/projector.ts:119-157 scopes writes by message and Session IDs and defines current assistant as only the latest assistant row by descending sequence, returned only if incomplete.
  • :159-176 gets an explicitly owned assistant by both message ID and current Session and validates type "assistant".
  • :370-382 projects durable PromptAdmitted into SessionInput.
  • :391-431 requires a durable sequence for Step.Recovered, verifies a referenced assistant is still latest and is an assistant, admits queued Prompt.make({ text: "continue" }), applies normal event projection, and inserts recovery identity.
  • Exact defects: Durable Session event is missing aggregate sequence, Recovery target is not the latest assistant: ${event.data.assistantMessageID}, and Recovery target is not an assistant: ${event.data.assistantMessageID}.
  • Revert cleanup at packages/core/src/session/projector.ts:486-490 deletes only Session inputs admitted/promoted after the revert boundary.
  • packages/core/src/session/message-updater.ts:95-99 updates only the explicitly owned assistant.
  • message-updater.ts:155-239 creates new assistant messages on step start and scopes ended/failed/interrupted settlement to assistantMessageID.
  • message-updater.ts:237-281 maps recovered "unknown" to Provider Step outcome unknown after server restart, otherwise Session execution interrupted by server restart.
  • Recovery without an assistant appends a synthetic recovery message. With an assistant, it completes that assistant with finish = "error", appends recovery:${executionID}, and converts pending/running tools to unknown errors. Final inspected text is Tool execution outcome unknown after server restart; an intermediate frozen-patch excerpt used Tool execution outcome unknown after interruption, so final patch/current-line evidence must be quoted precisely.
  • In-memory projection mirrors the latest-only rule using findLastIndex; it never falls back to an older incomplete assistant.

• Events and replay

  • packages/core/src/event.ts:316-353 runs durable projectors and optional commit hook, updates aggregate sequence, and inserts event in one immediate transaction.
  • :354-360 emits durable aggregate wake notifications only after commit.
  • :369-395 rejects commit hooks on non-durable events with InvalidDurableEventError and exact message Local commit hooks require a durable event.
  • :398-415 logs non-interruption listener failures as Event listener failed with event ID/type/cause.
  • :441-475 replay supports publish, ownerID, and strictOwner; listeners are notified only when a new commit occurred and publish is true.
  • packages/schema/src/session-event.ts:32-56 uses durable version 1 generally and version 2 for step settlement.
  • :185-219 defines Step.Failed, Step.Interrupted, and Step.Recovered; recovery phase is "ready" | "unknown".
  • :423-504 defines compaction started/delta/ended. Started/Ended are durable; Delta is live-only.
  • Live-only fragments also include Text/Reasoning/Tool Input deltas; replayable full-value boundaries are corresponding Ended events.

• Runner and tool behavior

  • packages/core/src/session/runner/index.ts now requires executionID in run({ sessionID, force, executionID }); it performs one local continuation from recorded history.
  • runner/llm.ts threads execution ID through runTurnAttempt(...), validates claims, and defects with Session execution claim lost: ${executionID}.
  • Execution phases transition through "ready", "safe", and "unknown"; inspected changes set "safe" after committed stream boundaries and "unknown" when outcome is uncertain.
  • runner/llm.ts:121-141 has failInterruptedTools, which scans pending/running tools and emits unknown Tool.Failed events while preserving provider executed and metadata. An inspected current snapshot still used Tool execution interrupted, so candidate-vs-current wording needs exact patch verification.
  • runner/llm.ts:143-144 defines awaitToolFibers = Effect.raceFirst(FiberSet.join(fibers), FiberSet.awaitEmpty(fibers)).
  • User declines (PermissionV2.DeclinedError, QuestionV2.RejectedError) stop the loop rather than becoming tool output.
  • publish-llm-event.ts tracks assistant/tool ownership, timestamps, text/reasoning deltas, durable tool definitions, settlement, and assistant failure state.
  • Search found the string ``SessionPrompt monolith. Implement the unchecked items in small reviewed slices: at runner/llm.ts:49; this is textual/commentary evidence, not itself a legacy call. The invariant is no actual SessionPrompt invocation.

• Compaction

  • packages/core/src/session/compaction.ts:155-179 token-splits conversation and creates fresh/update summary prompts.
  • :184-242 validates context/output bounds, publishes Compaction.Started, runs a tool-free summary stream with bounded output, invokes optional beforeStream/afterStream, rejects provider failure/blank summary, and publishes durable Compaction.Ended with summary and recent tail through the supplied commit hook.
  • :244-259 auto-compacts only when configured and estimated system/messages/tools exceed context - max(output, buffer).
  • Overflow continuation routes through runAfterOverflowCompaction(...).

• Session input

  • packages/core/src/session/input.ts:85-116 admits one row, rejects existing projected messages or failed insertions with LifecycleConflict.
  • :118-168 makes prompted projection idempotent only when stored projection and promoted sequence match exactly; otherwise it defects.
  • packages/core/src/session.ts:360-385 runs prompt admission uninterruptibly, maps lifecycle conflict to PromptConflictError, checks retry equivalence, and wakes unless resume === false.
  • session.ts:346-358 exposes durable filtered streaming and aggregate history.
  • session.ts:387-391 returns OperationUnavailableError for "shell" and "skill".

• Startup composition

  • packages/server/src/routes.ts:27-39 includes SessionRecovery.node in application services.
  • packages/server/src/routes.ts:53-55 substitutes SessionExecution.node with SessionExecutionLocal.node.
  • packages/opencode/src/server/routes/instance/httpapi/server.ts:299-304 groups SessionV2.node and SessionRecovery.node and supplies both LocationServiceMap.node and SessionExecution.node substitutions.
  • :307-312 keeps Observability.layer last to avoid TUI logger corruption (#34730).

• Tests

  • packages/core/test/session-execution-local.test.ts:42-160 contains six enumerated behaviors despite one observation calling them “5 tests”:
    1. successful resume clears claim;
    2. scope closure preserves a running claim;
    3. explicit interruption clears claim;
    4. second owner cannot run under a live lease;
    5. expired lease takeover runs replacement and fences stale owner;
    6. same owner does not re-enter an uncertain live lease.
  • Exact key cases:
    • :81-102 live-lease exclusion
    • :104-133 takeover/stale-owner fencing
    • :135-160 uncertain-live non-reentry
  • packages/core/test/session-projector.test.ts includes:
    • never recovers a live execution lease using expires_at: Date.now() + 60_000
    • never recovers an execution superseded by a newer assistant using sequences 0 and 1
    • duplicate startup scan/idempotency asserting exactly one recovery row, one continuation row, one synthetic message, and no execution claim.
  • Required future regression set: takeover, restart, replay idempotency, claim lifecycle, duplicate recovery, and stale-owner fencing, followed by package typechecks, focused tests, and migration validation.

• Working-tree evidence

  • At 01:38 and 06:08, 20 tracked files were modified and 3 files were untracked (20260914235657_session-execution-lease.ts, perf.data, perf.data.old).
  • At 13:38, the 20-file tracked diff totaled 490 insertions and 237 deletions.
  • Later status at 13:42 also exposed the three earlier September migration files and server route files as delta content. This reinforces that transient Git status does not fully describe canonical scope.
  • git show at 07:49 produced: fatal: path 'packages/core/src/database/migration/20260914235657_session-execution-lease.ts' exists on disk, but not in 'dc661f30cb2055ad6248fdc59b14998d834497be' and lease-exists=128, proving the lease migration belongs to the frozen delta rather than HEAD.
  • Unidentified tool hashes/results that should not be treated as candidate verification:
    • 06:21: 33e64fbe08c166aefbfc3c5f1afd9e432aaa60c06e95d8e273163fc2c38b5142 -
