Compression nudges now guide WHAT to compress (completed tool outputs, exploration results) instead of just WHEN (threshold). Key changes: Per-message injection (utils.ts + system.ts): - Replace 'Context is ample — do NOT compress' with proactive guidance - 'Keep context lean — compress large shell outputs, diffs, and logs' - 'You can decompress later; nothing is permanently lost' - 'Preserve verbatim: user instructions, decisions, file paths, findings' Turn/context-limit nudges (turn-nudge.ts + context-limit-nudge.ts): - 'compress now' → 'if you've finished reading, compress' - 'CRITICAL MUST NOW' → 'time to compress largest ranges you no longer need' - Both include decompression safety net Per-message block guidance (extensions/nudge.ts): - Add 'When you've finished using tool outputs, compress them' Design rationale: past aggressive nudges caused reckless deletion. Decompression capability makes compression reversible, enabling more proactive compression with lower risk. The old 'ample = don't compress' guidance was causing models to never compress at low context levels, wasting tokens on verbose completed tool outputs. Oracle review: APPROVE_WITH_NITS (both addressed)

Restructures ACP compression nudges from binary threshold-driven to principle-driven (be frugal, compress proactively, decompress later). 5 files, +21/-14 lines. Tested locally for 2 days.
