OpenCode V2: every turn refused in silence with 0.43.2 — v2 refuseIfUnsafe / "context storage is not durable" (outcome=interrupted, no assistant message) #546

Summary

On OpenCode V2 (2.0.18), loading @cortexkit/opencode-magic-context (npm latest 0.43.2, freshly installed) makes every session turn die in silence: the user message is stored, the turn is refused before the provider call, the host records idle {outcome:"interrupted"} ~60–360 ms later, and no assistant message is ever produced. The TUI shows no reply and no visible error. Same symptom class as the closed #493; still reproducible with the current npm release on this host.

Environment

• OpenCode V2: 2.0.18 (both ~/tools/ocv2/opencode and ~/.opencode/bin/opencode2), Linux
• magic-context: 0.43.2 — reproduced with the previously cached install and with a fresh install after clearing ~/.cache/opencode/npm/@cortexkit/opencode-magic-context@latest (new cache dir created, version verified 0.43.2)
• V1: 1.18.32 with the same plugin on the same host works normally (its Magic Context transforms run; see the plugin log)
• Context store: ~/.local/share/cortexkit/magic-context/context.db (118 MB, journal_mode=wal, WAL ~6 MB, actively written; the store is V1-era — the plugin log contains historical refusing to migrate … from upstream migration v79 to v85 lines from 2026-09-24)
• ~/.local/share/opencode/opencode.db is ~2.7 GB and shared by V1+V2 on this host

Symptom / evidence

session_message rows (~/.local/share/opencode/opencode.db) for a refused turn:

seq 4  user  "say PB-shared"              t=…4983132
seq 5  idle  {"outcome":"interrupted"}    t=…4983492   ← 360 ms later; no assistant row

Console trace at refusal time (observed in a standalone V2 run):

[magic-context] v2 refuseIfUnsafe warn: context storage is not durable

Timeline: last successful assistant message = 2026-09-26 21:28:52 (before V2 had ever loaded plugins on this host); the V2 plugin caches were first populated 21:34–35 that day; every V2 turn since has been interrupted.

Controlled experiment (minimal repro)

Standalone V2 server (opencode --standalone, isolated XDG_CONFIG_HOME) with a minimal opencode.json containing exactly one plugin entry; submit a message; read session_message.outcome:

Code pointers (master)

• packages/plugin/src/v2/hooks/context.ts:709 and :838 — if (!db || !isDatabasePersisted(db)) throw new Error("context storage is not durable");
• packages/plugin/src/v2/hooks/context.ts:277 — reportPreProviderRefusal() → console.warn("[magic-context] v2 refuseIfUnsafe", error); its comment states the host then stores the turn as interrupted and the user simply never receives a reply — no error on screen and no assistant message.
• packages/plugin/src/v2/hooks/context.ts:1291–1305 — refusals are thrown as V2ContextRefusal (a fail-open branch exists only for compactionOff).
• packages/plugin/src/features/magic-context/storage-db.ts:2529 — isDatabasePersisted(db) returns a WeakMap flag set during database open; getDatabasePersistenceError(db) holds the reason and is not surfaced anywhere user-visible.
• On this host the plugin's own session log ($TMPDIR/opencode/magic-context/magic-context.log) contains no v2 refusing this turn before the model call lines for the V2 refusals — the only trace is the console warning.

Related

• opencode plugins: V2 primary-session prompt hangs when @cortexkit/opencode-magic-context@0.42.6 is loaded #493 (closed): V2 prompts hang with 0.42.6 — "fixed on master" comment at 2026-09-25T19:03Z; npm latest 0.43.2 was published 2026-09-25T11:25Z, i.e. before that comment. If the fix isn't in 0.43.2, this report is the released-channel recurrence; if it is, this refusal path (context storage is not durable) appears to be a distinct one.
• OpenCode V2: first-request history reconciliation blocks the event loop for 154 seconds on a large migrated session #536 (open): first-request history reconciliation blocking on a large migrated session — the store here is also large and V1-migrated.

Expected

• Degrade / fail open when durable context storage cannot be established (or at minimum surface a user-visible refusal reason), instead of silently killing every turn.
• If this is the opencode plugins: V2 primary-session prompt hangs when @cortexkit/opencode-magic-context@0.42.6 is loaded #493 class: the v2 store reader should accept, repair, or doctor-guided migrate the store present on this host.

Repro steps

1. V2 config with only this plugin: {"$schema":"https://opencode.ai/config.json","plugin":["@cortexkit/opencode-magic-context@latest"]}
2. opencode --standalone (or any V2 server) and send any prompt.
3. Observe: no assistant reply; session_message = user → idle {outcome:"interrupted"}; console = v2 refuseIfUnsafe + context storage is not durable.
