+'@objectstack/objectql': patch
+---
+
+fix(objectql): a bound action named like an action its target object already lists, with a different declaration, is reported at boot naming both packages; `registerAction` reports replacing another owner's handler
+
+Clause-②: no (a warning only: no accept set narrows, no door answer moves, and no published surface gains a key; owes the seat's review of record before the queue)
+
+- **The listing.** A top-level action bound by `objectName` to an object that already lists an action of the same name is still not attached: the object keeps serving its own declaration, as the action router does. When the two declarations differ, the boot now warns once per pair, at `kernel:ready`, naming the object, the action, the package whose declaration is served and the package whose declaration is not listed. Two packages binding different declarations of one name to a third package's object are reported the same way (the first one attached is served).
+- **Not a collision.** One declaration carried twice is compared without its provenance stamps (`_packageId`, `_provenance`, the `_lock` envelope, `protection`) and without `objectName`, and is not reported: a same-stack bound action merged onto its object, or the same declaration shipped by two packages.
+- **Later artifacts.** An artifact registered after the boot (a marketplace install, a ledger rehydrate) is judged once it has registered, for the pairs naming one of its packages; a pair the boot already reported is not reported again.
+- **The handler.** `ObjectQL.registerAction` keys handlers by `OBJECT:ACTION`. A registration under a key another owner holds still replaces it (the last registration runs), and now warns, naming both owners: the action door runs the new owner's handler whichever declaration the object lists, and withdrawing that owner leaves the action with no handler. The same owner re-registering is silent, and so is the authored-action resync, which tears its set down first. A registration with no package is its own owner.
+- **Unchanged.** Nothing is refused and no boot fails on it; the served `actions`, the router's precedence and which handler runs are as before. Measured on stock CRM, showcase and todo boots: no new warning.
+- **Fix.** Rename one of the two actions, or drop the duplicate declaration.

 ### Which surfaces this covers
 
 **All of them.** It was not scoped to an experimental corner or a pre-release channel: all **73** packages published from this repository belong to a single Changesets `fixed` group, so they share one version number and one policy. No published surface was exempt.
 
-The convention was enforced rather than informal — `scripts/check-changeset-no-major.mjs` failed a pull request that introduced a `major` bump, because under lockstep a single `major` on one package would promote the entire stack. Changesets is now in pre mode with the tag `next`, and the guard stands aside in pre mode, so a pull request on the v18 line may declare a major bump.

Changesets has exited pre mode, and the guard fails a `major` bump again.
 
 ### What this means for an upgrade
 
 - **Do not read a MINOR bump as safe to take unattended.** Read the [release notes](/docs/releases) for the version you are moving to: they lead with breaking changes and carry the migration steps.
 - **Pin exact versions** instead of caret ranges if you cannot review each MINOR before it lands.
 - **Diff your own metadata** across the upgrade with `os diff <before> <after> --breaking-only`.
 
-MAJOR releases do still happen — 17.0.0 was cut precisely because its breaking density was too high to carry `^16.x` consumers across on a caret range, and the v18 line is a major in prerelease — but in the 17.x minors an individual breaking change did not, on its own, force one.

 ### When it stops applying
 
-The tables and deprecation timeline above state this rule for the 17.x minors directly, beside what the v18 line does. Classic SemVer — where a breaking change once again requires a MAJOR — is the settled form the project returns to once the launch window closes: the window closes at GA, and strict SemVer resumes from that point. **For the 17.x minors, this section was the operative rule wherever any part of this page disagreed.** For the `18.0.0-next.N` prereleases, the operative rule is [how a breaking stage lands on the v18 line](/docs/releases/v18#how-a-breaking-stage-lands-on-this-line).
