Two corrections found by measuring the first cut of the guard against the 6-repo suite. The first version held back the FULL sum of the reservations below a file. On django that took 2,319 chars off a file the agent receives and handed them to a section the hard ceiling then threw away — the guard's own failure mode, one layer down. tokio lost 1,298 the same way. 1. `owedPayableBelow` — hold back only the prefix of what is owed below that the response can still PAY, in rank order. A promise the ceiling cannot reach is not a claim on this file's bytes. 2. The final truncation now spends the EPILOGUE before it spends a rendered file section. It used to cut at the last section header, dropping that section AND the trailing notes; dropping the notes alone is almost always enough. A section is source the agent otherwise has to Read; the epilogue is a pointer list and two reminders, and the note that replaces it carries the "explore these names" instruction forward. Also count `flow.text` in `totalChars`. It is prepended to `lines` to make the final output, so the render loop always spent against a ceiling it was ~2K under on symbol-bag queries. Deterministic, same clean-rebuilt indexes, both builds (baseline = CG-30 tip): repo base source new source files django 20,033 20,791 5 trunc -> 6 excalidraw 18,776 20,204 7 trunc -> 8 okhttp 15,628 19,034 4 trunc -> 5 tokio 20,340 21,521 4 trunc -> 5 gin 10,776 10,776 4 -> 4 (byte-identical) alamofire 11,662 11,662 2 -> 2 (byte-identical) No repo delivers less; four stop truncating. `funded` in the diagnostic now reports the render CEILING the guard allows, which is what every render path is actually bounded by.
