| 3 | 1. **P2 — Exempt skipped paths still cause unbounded ancestor processing.** The exemption at [publisher.go:74](/home/paulca/amadan.net/carlos/platform/.claude/worktrees/hostfiles-cap-live-entries/internal/hostfiles/publisher.go:74) admits arbitrarily deep skipped paths. Both Restore and Present call [superseded():226](/home/paulca/amadan.net/carlos/platform/.claude/worktrees/hostfiles-cap-live-entries/internal/hostfiles/restore.go:226), which walks every ancestor, including those of skipped entries. Each `path.Dir` cleans the remaining prefix, making this quadratic in depth, with no cancellation check. A valid skipped entry at `strings.Repeat("d/", 100000)+"f"` therefore causes substantial uncancellable work even on an empty destination. Bound or redesign overlap processing while preserving skipped entries’ sequence semantics. |

| 5 | 2. **P2 — A skipped flag bypasses the cap on a tombstone.** At [publisher.go:74](/home/paulca/amadan.net/carlos/platform/.claude/worktrees/hostfiles-cap-live-entries/internal/hostfiles/publisher.go:74), an over-cap entry containing both `Deleted: true` and `Skipped: "too-large"` passes validation. Neither decoding nor `checkEntry` rejects that combination. Restore gives `Deleted` precedence at [restore.go:109](/home/paulca/amadan.net/carlos/platform/.claude/worktrees/hostfiles-cap-live-entries/internal/hostfiles/restore.go:109), then performs the ancestor marking and removal that the revised design intends to forbid. This requires a malformed or crafted manifest; normal writers do not produce it. Exempt only `!e.Deleted && e.Skipped != ""`, or reject contradictory states consistently. |

| 7 | The remaining requested checks: |
| 8 | |
| 9 | - Round 3’s findings against `removePastCap` are moot: that implementation is gone. |
| 10 | - For ordinary skipped entries, the StageDelete no-op is safe: it preserves an unpublished entry and cannot resurrect content. Restore → scan → commit succeeds when the deep file and over-cap directories are absent. |
| 11 | - An existing deep file or directory still makes scanning—and therefore flushing—fail. That is the existing scan-cap limitation described in the brief as #279-class. |
| 12 | - CopyManifest, NewFromCopy, and moves’ Establish consistently carry ordinary skipped entries through the shared validation. |
| 13 | - The census overlay is envelope-only; its hash matches exactly. Plan 9 and Plan 14 legacy units and the legacy seal are unchanged. |
| 14 | |
| 15 | Static review only; no tests ran, including the full `internal/host` suite. |

| 17 | --- |
| 18 | |
| 19 | **FIRST PROMPT:** |
| 20 | Review the round-4 brief at `c6dc57d0`, read-only; avoid the full internal/host suite. |
| 21 | |
| 22 | **WHAT:** |
| 23 | Assess the revised cap, downstream recovery behavior, census, and merge readiness. |
| 24 | |
| 25 | **STATUS:** |
| 26 | Complete: two P2 findings; request changes. |
| 27 | |
| 28 | **NEEDED:** |
| 29 | Nothing from you for this review. |
| 30 | |
| 31 | **RECOMMENDED:** |
| 32 | Address both findings and add focused regressions before merging. |
| 33 | |
| 34 | **SESSION:** |
| 35 | Safe to close. HEAD and working tree are unchanged; no files or background processes were created. |
