Title: Runs repeatedly aborted by Provider finish_reason: network_error — no auto-retry, long sessions die mid-task

Version: OpenCode.app 1.18.21, macOS Sequoia (Apple Silicon)

Provider / model: opencode / x-preview-f-free

What happened

On 23 Aug 2026, long-running agentic sessions kept dying mid-task with:

ERROR message=process error="Provider finish_reason: network_error"
stack="ProviderResponseStreamError: Provider finish_reason: network_error
    at Object.toLLMEvents (...node-4c_8o6aE.js:448336:36)"

18 occurrences across 4 distinct sessions between 09:47 and 20:07 UTC. One session
("Felloh - Dolphin booking payment link via Playwright", ses_fd0defd6dffehQvpBJ243vQIrh)
was hit 9 times over ~1 hour and became effectively unusable — every retry died the same way,
and I eventually had to reconstruct its compaction summary by hand into a markdown handoff file.

The local network was fine throughout (browsing, git, npm all working normally, other apps unaffected),
and the failures span 10+ hours, so this looks like upstream/stream handling rather than my connectivity.

Expected behaviour

A transient mid-stream failure should be retried automatically (a few attempts with backoff)
before surfacing an error to the user — ideally resuming from the last received chunk so the
run survives instead of aborting.

Actual behaviour

The run aborts immediately; the user must manually re-send, and repeated occurrences make
long sessions unworkable and risk losing compaction state.
