shrinkCluster keeps an oversize cluster's highest-importance member WHOLE on purpose — an empty file section sends the agent to Read, the outcome explore exists to prevent. What it lacked was a bound, and "never empty" quietly meant "never bounded": on the reporting repo one file emitted 22,376 chars against a 9,181-char reservation (2.44x), past both the per-file budget and the spine ceiling. That overshoot is what collapses `headroom` for every file below it. The same rule has a second face. When the top member is bigger than the whole response ceiling, the file does not overshoot — it is dropped entirely at the renderCeiling check, so the agent gets nothing for a file it named. renderCluster now takes a ceiling (1.5x what the file may spend — the same multiple SPINE_CEILING already draws, and never below the cap, so a cluster that fits is untouched). Past it the member is WINDOWED on whole lines rather than emitted whole or dropped: leading window plus, on a flow cluster, a window on the spine's call site. A partial window shorter than 12 lines is dropped instead — a sliver in the session record forces the next call's dedup to shred the block around it or re-send it — unless nothing else was emitted, where the never-empty floor wins. Measured on the new fixture, pre-fix vs post-fix: monthly.ts 12,391 chars on a 3,334 budget (3.7x) → 4,941 (1.48x) quarterly.ts dropped, no headroom left → 4,004 delivered Also: the diagnostic now reports `spendable` (reservation + inherited slack) alongside `reserved`. Every render bound reads the former, so reporting only the latter makes an ordinary carry-forward read as a file spending over budget — and it made the overshoot this issue is about unmeasurable. A windowed file is now flagged `clipped` too, instead of presenting a window as the whole file. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
