• 🟡 (01:31) Disposable recovery harness /tmp/opencode/session-recovery-v18-smoke.mjs targeted /home/byk/Code/opencode/packages/opencode/dist/server/opencode-server with isolated root /tmp/opencode/session-recovery-final-v18, database /tmp/opencode/session-recovery-final-v18/opencode.db, workspace /tmp/opencode/session-recovery-final-v18/workspace, randomized ports from 10,000 through 29,999, authenticated /global/health probes, 20,000 ms startup/settlement deadlines, 1,000 ms fetch timeout, and 50 ms polling.
• 🟡 (01:31) /tmp/opencode/session-recovery-v18-smoke.mjs isolated HOME, XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_STATE_HOME, and XDG_CACHE_HOME; set OPENCODE_DB and OPENCODE_SERVER_PASSWORD; and set OPENCODE_DISABLE_DEFAULT_PLUGINS, OPENCODE_DISABLE_EMBEDDED_WEB_UI, OPENCODE_DISABLE_EXTERNAL_SKILLS, OPENCODE_DISABLE_PROJECT_CONFIG, OPENCODE_DISABLE_LSP_DOWNLOAD, OPENCODE_DISABLE_CLAUDE_CODE, OPENCODE_DISABLE_CLAUDE_CODE_PROMPT, OPENCODE_DISABLE_CLAUDE_CODE_SKILLS, OPENCODE_DISABLE_AUTOUPDATE, and OPENCODE_DISABLE_SHARE to "1".
• 🟡 (01:31) Recovery smoke seeded project global, session ses_recovery_final_v18, and ready execution recovery-final-v18 owned by dead-owner, then tested initial migration, recovery discovery, forced expiry, continuation, event ordering, and a third restart with no additional durable changes.
• 🟡 (01:32) Exact SEA recovery smoke passed four isolated authenticated launches on ports 17281, 25151, 15661, and 17709; every /global/health response was {"healthy":true,"version":"1.18.30"} and every launch had empty stderr.
• 🟡 (01:32) Recovery smoke verified schema defaults: session.wake_attempts=0, session_input.wake_pending=false, session_recovery.wake_pending=true, and session_recovery.wake_attempts=0.
• 🟡 (01:32) Recovery smoke verified index session_execution_recovery_scan_idx exists with SQL CREATE INDEX \session_execution_recovery_scan_idx` ON `session_execution` (`recovery_error`,`expires_at`,`time_created`,`id`)`.
• 🟡 (01:32) Recovery smoke durable counts changed from execution_count=1, recovery_count=0, input_count=0, message_count=0, event_count=0 before recovery to execution_count=0, recovery_count=1, input_count=1, message_count=2, event_count=2 after the second recovery launch.
• 🟡 (01:32) Recovered row for execution recovery-final-v18 ended in phase ready with wake_pending=0, wake_attempts=2, and recovery_error=null.
• 🟡 (01:32) Exactly one queued continuation input was created: ID msg_recovery_continue_recovery-final-v18, prompt {"text":"continue"}, delivery queue, promoted_seq=1, and wake_pending=0.
• 🟡 (01:32) Recovery emitted exactly two ordered events: sequence 0 type session.next.step.recovered.1, then sequence 1 type session.next.prompted.1.
• 🟡 (01:32) Third restart was idempotent: counts remained execution_count=0, recovery_count=1, input_count=1, message_count=2, and event_count=2, confirming no duplicate continuation, messages, or events.
• 🟡 (01:32) Built SEA artifact packages/opencode/dist/server/opencode-server had SHA-256 753b05afb86195246b211237ca5b11e26a7c08da863d70a711da2c93ee453c8a; post-smoke process inspection found no disposable server remaining.
• 🟡 (01:32) Candidate-freezing scope explicitly excluded .lore.md, AGENTS.md, perf.data, and perf.data.old.
• 🟡 (01:33) First frozen patch /tmp/opencode/session-recovery-final-v19.patch had SHA-256 18af75f50e1f6aabfbaa61da329a8c14c176b405c63e11fce8f944cc664b32e4, contained 33 paths with 8,418 insertions and 463 deletions, but incorrectly omitted sibling file packages/core/src/session.ts because the pathspec covered packages/core/src/session/ rather than the adjacent file.
• 🟡 (01:34) Corrected frozen patch /tmp/opencode/session-recovery-final-v19.patch replaced the first freeze, had SHA-256 a2bce01664538243cb8ba16c6ca8f0364c6f79463ad6677567044a1b3e1e74fe, and contained 34 paths with 8,424 insertions and 467 deletions.

• 🟡 (01:34) A detached validation worktree was prepared at immutable base commit ab9408c81c (feat(app): adapt vertical tab density).
• 🟡 (01:35) Corrected patch a2bce016…e74fe applied cleanly to immutable base ab9408c81c and passed whitespace checks in the detached worktree.
• 🟡 (01:35) Two independent background reviews were launched against exact patch a2bce01664538243cb8ba16c6ca8f0364c6f79463ad6677567044a1b3e1e74fe and SEA 753b05afb86195246b211237ca5b11e26a7c08da863d70a711da2c93ee453c8a: correctness task ses_f52ff5084ffe7snDvSQgJjIjEs and security task ses_f52fef029ffe2a2CGDN98jGF2v. Review focus included coordinator-cleanup cancellation settlement and explicit-resume crash recovery.
• 🟡 (01:35) Final validation status reported: 1,187 core tests passed, 250 recovery-gate tests passed, six package typechecks passed, exact isolated artifact smoke passed, and live services remained untouched.
• 🟡 (01:35) Work items completed: preserve cancelling claims when interruption settlement defects; persist explicit resume intent before pending-input promotion; add bounded recovery claim scan index; regenerate current client contracts through packages/client; and run full package validation plus isolated artifact restart smoke. Remaining in progress: freeze revised candidate and obtain independent correctness and security approval.
