Address the 11 confirmed bugs and 4 cleanups from context-pruning-and-framing-review.md, plus the image-accounting regression it found on a second pass. classifier framing: - _previous_context walks back to the nearest assistant turn only, skipping system/user/tool so raw tool output and the system prompt never contaminate the framing signal; reuses context_prune.extract_text instead of a duplicated block parser. - classify() drops its redundant if/not-context branch. - framing instruction moved out of the static system prompt and into _classifier_user_content so it travels only with content that justifies it (respects context_framing opt-out). context pruning: - extract_text counts image_url bytes so image-bearing tool results are sized (and pruned) correctly. - -- new, follow-up review -- image_url blocks now count toward the size trigger but not toward the replacement text, and are stubbed to a short marker when the message is trimmed, so an image-heavy tool result genuinely shrinks rather than staying full-size while tokens_saved lied and base64 leaked into the text block. - tokens_saved is now the honest whole-list before/after reduction (max(orig - final, 0)), never a per-message estimate that could drift. - max_summarize_chars validated >= 3000 at config load; trim branch guards against negative math and message growth. - recency guard protects the newest tool result even with no user turn. - non-text blocks survive trimming (type preserved) rather than being flattened away. - dropped/stat terminology corrected to summarized; _turn_of() removed; module-level pinch defaults removed in favor of PinchConfig. Dispatch and config: - prune_context runs once before the measured-context routing decision (reused at dispatch, no double-prune, no in-place mutation); no-op when pinch is disabled. - dead context=prev_context arg removed from the measured reroute. - TaskRequest.context dual use documented. 15 new regression tests pin the fixes; 545 tests pass.
