* enhance(#4261): report size-cap headroom on every run, with a reserved margin The tier caps are red lines and none of them moves here. What was missing is everything below the red line: a passing run said nothing, so a contributor at 99.6% of a cap and one at 60% got identical feedback, and the density that produces merge-time collisions was invisible to the people creating it. Two levels, matching the shape execute-phase.md already carries by hand (a hard ceiling plus a lower margin "so minor future edits don't re-trip the gate") and which was until now the only capped file with one: 1. a headroom census printed every run, green included, sorted least-headroom-first, and appended to the GitHub job summary 2. a 95% reserved margin that names the files inside it and REPORTS rather than fails The margin deliberately does not fail. A cap breach is a red line; a file at 96% is not broken, it is a file whose next contributor should extract before adding. Failing there would create a second red line and force exactly the +N bumps the policy forbids. Neither level asserts a count, so this adds no snapshot to regenerate — the per-file size baseline was deleted by #2724 for conflicting on 7 of 7 PRs that touched it. Also deletes rather than refreshes the per-tier high-water comments in both guard files. They were measured once and then diverged from the tree: the LARGE line still claimed "gsd-executor 42,342 -> ~6.8 KB headroom" while the real high-water sat at 99.6% of that cap, so the comment documenting the margin was itself why nobody noticed the margin was gone. As measured on next by the new census, the pressure has grown since the issue was filed: gsd-plan-checker.md has 9 bytes of headroom, gsd-verifier.md 21, and plan-phase.md 14. * chore(#4261): add changeset for the size-cap headroom census * test(#4261): exercise reserved-margin boundaries --------- Co-authored-by: Tom Boucher <trekkie@nomorestars.com>

Size-cap checks expose pressure before the hard limit — workflow and agent suites report every capped file's remaining headroom and flag files past the 95% reserved margin. (#4261)
