skills(automation): delete the planned-eval stub and drop its ceiling row (#14296 item 2)

[os-litant]

Fixes #14308

#14296 item 2 = A, comment 5507419465 (09:27Z, 1A 2A 3A 4A): the planned-eval stubs are deleted and their ceilings step down; real fixtures stay. This is round 2 of #14308 — round 1 (PR #14467, merged) implemented every finding in skills/objectstack-automation/SKILL.md and deferred AUTO-B-04, the evals/README.md planned-eval stub, to this ruling. Per the round-1 ACCEPT comment (5506911275), AUTO-B-04 is the only deferred item recorded for this card, so this round closes it.

Verified before touching anything: evals/README.md's "Planned structure" ASCII tree lists four files that do not exist anywhere in the repo (evals/approvals/test-quorum-behaviors.md, evals/flows/test-schedule-binding.md, evals/flows/test-decision-edges.md, evals/triggers/test-time-relative.md) — it is the planned-structure stub, not a real fixture. skills/objectstack-automation/SKILL.md has zero references to evals/ (grep, 0 hits), so nothing links to the deleted file, and nothing in the repo outside scripts/check-skills-token-ratchet.mjs names its path.

The two-file diff

file	change
skills/objectstack-automation/evals/README.md	deleted (414 tokens, 43 lines — the template listing planned eval files that do not exist)
scripts/check-skills-token-ratchet.mjs	one row dropped: ['skills/objectstack-automation/evals/README.md', 414] — the only edit to that script this flight makes

No prose edit anywhere, no new file, no ceiling raised, no other package touched. The real fixture skills/objectstack-automation/evals/approvals/test-revise-loop.md and its ratchet row (ceiling 1329, currently 550 tokens / headroom 779) are untouched.

Reverse verification — the ratchet red → green pair

Before dropping the row (file deleted via git rm, row still present):

$ node scripts/check-skills-token-ratchet.mjs
✗ check-skills-token-ratchet: cannot read skills/objectstack-automation/evals/README.md — red, not a skip (#4690).

exit 1 — matches the header's documented behaviour exactly: "Missing file or empty read is RED, never a pass (#4690: a gate that cannot find its input must fail, not skip)."

After dropping the row:

$ node scripts/check-skills-token-ratchet.mjs
✓ check-skills-token-ratchet: skills/objectstack-automation/SKILL.md is 12269 tokens (ceiling 12768; headroom 499).
✓ check-skills-token-ratchet: skills/objectstack-automation/evals/approvals/test-revise-loop.md is 550 tokens (ceiling 1329; headroom 779).
✓ check-skills-token-ratchet: skills/objectstack-automation/references/_index.md is 835 tokens — generator-owned (`pnpm --filter @objectstack/spec gen:skill-refs`), measured but not ratcheted.
✓ check-skills-token-ratchet: 36 authored bundle file(s) within their ceilings; 11 generator-owned file(s) measured, not ratcheted.

exit 0 (was 37 authored files before the deletion, 36 after — exactly the dropped row). --self-test: ✓ check-skills-token-ratchet self-test: 64 cases pass. (the row is keyed by exact relative path; nothing else in the self-test's fixtures or pinned counts depends on this row, so dropping it needed no other change).

Gates — head sha 81ec9d3d

Union re-derived after the final commit: node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands (checked against this checkout's origin remote — it holds) → 24 command(s), all run under scripts/pm/os-verify-lock.sh (OS_VERIFY_LOCK_SLOT=issue-14308-r2); every exit code captured before any pipe.

check:skill-docs (pnpm --filter @objectstack/spec check:skill-docs) → ✅ Skill docs in sync — no regeneration needed (neither generated file lists evals/). check:skill-compatibility and check:skill-identifier-liveness both green, unaffected by the deletion (the eval README carried no identifier binding: Leg 1 484 citations / Leg 2 8 exhaustive sections, both stable). check:published-readme-links green — 176 outbound links, 103/103 relative targets found (the deleted file was linked from nothing). node scripts/check-nul-bytes.mjs → clean (7953 text files scanned), plus a direct grep -naP C0-control scan of the changed script file, clean.

NOT MEASURED (2): node scripts/check-test-completeness.mjs exits 3, its own PREREQUISITE NOT MET code — needs a saved turbo run test log this run has no reason to produce; CI supplies it. pnpm --filter @objectstack/lint run check:doc-formula-expressions exits 3, PREREQUISITE NOT MET — the workspace package @objectstack/formula is not built; this flight touches neither formula nor its docs, so building it just to green a prerequisite gate would be verification-face padding on a two-file deletion; CI builds the closure and supplies a real reading.
