 **The Completeness Principle now asks for complete coverage with minimal code.** Every tier-2+ skill's preamble said "the complete thing is the goal", and ETHOS.md told models to "always prefer A" because "the 70-line delta costs seconds". Models read that as permission to write more code, which is the "50-line job arriving as 400" complaint (GSTA-93). Coverage of the requirement is still non-negotiable; code beyond it is no longer a virtue.
 
 ### Changed
-- **`scripts/resolvers/preamble/generate-completeness-section.ts`**: the default section reads "Complete coverage, minimal code": recommend full coverage of the requirement (tests, edge cases, error paths) and no code beyond it, prefer the smaller diff at equal coverage, and add no checks for impossible states. Unrelated work stays separate scope. The `Completeness: X/10` scoring rule and the GPT-5.6 Sol variant are unchanged. The section is 3 characters shorter, so every regenerated skill shrinks and 89 size pins go down.
+- **`scripts/resolvers/preamble/generate-completeness-section.ts`**: the default section reads "Complete coverage, minimal code": recommend full coverage of the requirement (tests, edge cases, error paths) and no code beyond it, prefer the smaller diff at equal coverage, and add no checks for impossible states. Unrelated work stays separate scope. The `Completeness: X/10` scoring rule and the GPT-5.6 Sol variant are unchanged. The section is 3 characters shorter, so every regenerated skill loses 3 characters from it and the 89 size pins go down by 3 (plan-ceo-review still grows overall, below).
 - **`ETHOS.md`**: "Completeness is cheap ... always prefer A" becomes "Complete coverage, minimal code": completeness is measured in coverage, not lines; at equal coverage choose the smaller diff; no speculative abstractions, impossible-state checks or unneeded refactors. A new anti-pattern names the impossible-state fallback. Section 1's opener now says "When covering the whole requirement costs minutes more than the shortcut, cover it. Every time. Complete means complete coverage, not more code.", and "How They Work Together" says Boil the Ocean means "cover the whole requirement with the least code" instead of "do the complete thing".
-- **`plan-ceo-review/SKILL.md.tmpl`**: the Philosophy bullet "COMPLETENESS IS CHEAP: AI makes 70 LOC seconds. Prefer complete ~150 LOC over 90% ~80 LOC. Boil the ocean." becomes "COMPLETENESS IS COVERAGE": cover the whole requirement (tests, edge cases, error paths) rather than a 90% shortcut, add no code beyond the accepted scope (so SCOPE EXPANSION and SELECTIVE EXPANSION still build what the user accepted), and choose the smaller diff at equal coverage. plan-ceo-review is under the 100,000-character limit on every host and has no size pin, so it grows about 100 characters without a pin change.
+- **`plan-ceo-review/SKILL.md.tmpl`**: the Philosophy bullet "COMPLETENESS IS CHEAP: AI makes 70 LOC seconds. Prefer complete ~150 LOC over 90% ~80 LOC. Boil the ocean." becomes "COMPLETENESS IS COVERAGE": cover the whole requirement (tests, edge cases, error paths) rather than a 90% shortcut, add no code beyond the accepted scope (so SCOPE EXPANSION and SELECTIVE EXPANSION still build what the user accepted), and choose the smaller diff at equal coverage. plan-ceo-review is under the 100,000-character limit on every host and has no size pin, so it grows about 110 characters without a pin change.
 - `review/specialists/simplification.md` quotes the new house rule instead of "If A is 70 lines more, choose A", and `CLAUDE.md` restates it in place of "Completeness is cheap ... the complete thing is the goal".
+- Left for a separate decision: the agents digest's Boil the Ocean bullet (`scripts/gen-agents-digest.ts`, regenerated into `agents-digest/gstack-AGENTS.md` at stamp time) and the first-run lake intro in `bin/gstack-skill-start` still say "do the complete thing".
 
 ### Tests
 - `test/model-overlays.test.ts` asserts the new default wording ("Complete coverage, minimal code.", "prefer the smaller diff") and checks, one sentence per rule, that the section still states full coverage of the requirement with no code beyond it, the smaller diff only at equal coverage, no checks for impossible states, and that unrelated work is separate scope that never excuses a gap.
