- Replaced time-based sleeps and polling loops with event-driven promise resolvers and fake timers across agent and tool tests.
- Migrated test suites to share in-memory auth storage and fixtures using lifecycle hooks.
- Updated catalog model definitions, metadata, and configurations.
Reverted branch-side edits to spawn-policy prompts/tests, settings tab
groups, mermaid cache typing, prewalk todo gating, and packages/ai test
churn back to merge-base content; trimmed their changelog entries. These
repaired stale CI against an older main and are stale or conflicting
against current main.
- Made resolveShapeForText choose silver16-bw for CJK-heavy auto transcripts while preserving explicit variants and unsafe glyph protection.
- Added silver16-bw to the snapcompact shape settings submenu and renamed unsupported-glyph warnings.
- Covered auto shape selection, explicit variant precedence, unsafe glyph scans, and settings option parity.
Fixes#4486
The auto-snapcompact non-ASCII fallback test seeded a single CJK turn with a
245k-token usage. claude-sonnet-4-5's 200k context window made that an input
overflow, so the recovery path dropped the assistant turn and left nothing to
summarize; the default 20k keep-recent window also kept both tiny messages.
Either way prepareCompaction returned undefined, the renderability preflight
never ran, and the strategy stayed "snapcompact" instead of downgrading to
context-full.
Derive the synthetic prompt size from the active model's context window (above
the auto-compaction threshold, below the window) and force keepRecentTokens=1
so the CJK history is always summarized and scanned, regardless of model
metadata.
After the overflow-recovery change started dropping the failed assistant turn before compacting, the non-ASCII fallback test's minimal transcript was left with nothing to summarize (the lone CJK message is kept-recent), so snapcompact was skipped and the run never exercised the non-ASCII downgrade. Bill the trigger turn just under the model's context window so it routes through the threshold compaction path (which keeps the turn) instead of overflow recovery, restoring deterministic coverage of the high-non-ASCII context-full fallback.
Auto-compaction now falls back to context-full on any snapcompact preflight or post-render rejection (non-ASCII, kept history too large, projection overflow), matching the text-only-model handling. Manual /compact snapcompact keeps its local-only failure contract per #3599.
Fixes#3659
