Collapse old conversation history into rendered PNG sections so the model reads a compact image instead of re-billed text, while preserving prompt caching and tool-call behavior. Measures real vs compressed token/cost. Core: - GPT history collapse (openai-history.ts): append-only, o200k token-length sectioning. Sections seal only at a tool-closed boundary (open call-id set empty), so a function_call and its function_call_output never split across the collapse cut. Fixes the OpenAI 400 "No tool call found for function call output with call_id ..." that hit long Responses-API sessions. - Anthropic cache contract (history.ts): append-only per-chunk rendering; cache_control markers are preserved/moved, never added; chunk boundaries align with caller marker seams for byte-stable prefix caching. - GPT image budget (openai.ts): detail:'original' for gpt-5.x, flagship vision-multiplier fix, patch cap; schema-strip preserves real descriptions. - Savings accounting (openai-savings.ts): cached_tokens + vision-token basis. Model scope (applicability.ts): - Default imaged scope = claude-fable-5 + gpt-5.6. - gpt-5.5 and claude-opus-4-8 stay opt-in: same pipeline, but they degrade reading dense imaged history (gist drift), so silently imaging them by default is wrong. Promotion is gated on an OCR/recall threshold. Dashboard: GPT + Anthropic rendering, per-family model toggles, persisted metrics, thumbnail-expired session UI, reflow/newline handling. Tests: cache-alignment (GPT + Anthropic), history sectioning + tool-boundary invariants, savings, dashboard, sessions/restart-restore. 452 passing.
