 # Changelog
 
+## [1.57.4.0] - 2026-06-08
+
+## **The completeness principle is now Boil the Ocean, matching the post it came from.**
+## **One name across the ETHOS file, every skill, and the developer-profile dial.**
+
+The principle that tells gstack to do the complete thing was called "Boil the Lake" in
+`ETHOS.md` and in every generated skill, with the ocean cast as the anti-pattern. The
+developer-profile system and the completeness intro link already used "boil the ocean"
+as the good, ship-the-whole-thing pole. So the same idea carried two opposite framings
+depending on where you read it. This renames the principle to Boil the Ocean everywhere
+and reframes the metaphor: the ocean is the complete destination, and lakes are the
+boilable units you ship on the way there. The guidance is identical. Only the name and
+the framing prose changed.
+
+### The numbers that matter
+
+Reproduce with `git diff v1.57.3.0..HEAD --stat`.
+
+| Property | Before | After |
+|---|---|---|
+| Principle name in ETHOS + every skill | "Boil the Lake" | "Boil the Ocean" |
+| Name vs. the `scope_appetite` dial ("boil the ocean" = complete) | split | unified |
+| Files updated | — | 63 (ETHOS, CLAUDE, README, resolvers, templates, generated SKILL.md) |
+| Runtime behavior change | — | none, text only |
+
+The one number that matters is zero: no behavior changed. A reviewer reading `ETHOS.md`
+no longer hits "ocean" as the thing to avoid in one section and the thing to aim for in
+the next.
+
+### What this means for you
+
+You get the same complete-the-work recommendations, now under the name from Garry's
+"Boil the Oceans" post. The metaphor reads straight through: the ocean is the goal,
+lakes are how you get there one boil at a time, and only genuinely unrelated
+multi-quarter migrations sit outside scope. Nothing to do on your end.
+
+### Itemized changes
+
+#### Changed
+- `ETHOS.md` section 1 is renamed to "Boil the Ocean" and reframed so the ocean is the
+  complete destination and lakes are the boilable first units, not the ceiling.
+- The "Completeness Principle" header injected into every tier-2+ skill now reads
+  "Boil the Ocean," with prose to match.
+- `CLAUDE.md` and `README.md` references updated to the new name.
+
+#### For contributors
+- Source of the rename lives in the preamble resolvers
+  (`generate-completeness-section.ts`, the `composition.ts` skip-list, and
+  `generate-lake-intro.ts`); all SKILL.md files are regenerated from them.
+- Unit assertions (`skill-validation`, `terse-build`) and the three ship golden
+  fixtures updated to the new header.
