docs: scope branch targeting to published packages, not a crate list - #3144
Conversation
The `dev` rule named six crates plus the wrappers, which left most of the published surface unaccounted for: `moq-mux` (0.9.8), `moq-json`, `moq-native` (0.19.12), `moq-token`, `kio`, `@moq/watch`, and `@moq/publish` are all depended on by version and none of them appeared. Breaking one read as a `main` change by the letter of the rule. Scope it to every package someone can depend on a released version of, and make `0.0.x` the exception rather than an implicit gap in the list. Cargo and npm treat each `0.0.x` release as its own incompatible version, so those packages promise nothing: `moq-audio`, `moq-video`, `moq-transcode`, and `moq-nvenc` break on `main`, as does anything unpublished. Also spells out that a source break need not be a renamed or removed item. Adding a field to a struct consumers build with a literal breaks them just as hard, which is what prompted this.

For breaking changes to moq-cli or moq-relay, this version-only rule now directs contributors to dev because both are published above 0.0.x. That contradicts the existing Releases section at line 68, which says these two crates intentionally take patch bumps for breaking changes because they have no external consumers and are released from main. Keep those exceptions in the targeting rule so contributors do not select the wrong base branch. (Written by GPT-5.6 Sol)
Useful? React with 👍 / 👎.
WalkthroughUpdated Merge Risk: 🔵 Low · up to The documentation now broadens branch-targeting guidance, but its final shortcut conflicts with the stated exception for unpublished or private packages and its explanation of 0.0.x compatibility should be framed as project policy. This creates a bounded risk of contributors routing changes incorrectly, so the PR is mergeable with explicit follow-up. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

| This covers **every package someone can depend on a released version of**, not a shortlist of the well-known ones: the `rs/` crates release-plz publishes, the `@moq/*` packages under `js/`, and the language wrappers under `swift/`, `kt/`, `go/`, `py/`. `libmoq` counts through its C ABI too, so a `moq.h` break is a `dev` change even though nothing depends on the crate. | ||

| **`0.0.x` packages are the exception: break them on `main`.** Cargo and npm treat every `0.0.x` release as its own incompatible version, so such a package makes no compatibility promise and has no contract to violate. That covers `moq-audio`, `moq-video`, `moq-transcode`, and `moq-nvenc` today. The same goes for anything marked `publish = false` or `private` (`moq-bench`, `moq-wasm`, `@moq/wasm`, `@moq/clock`), which isn't published at all. Reshape their surface freely, and prefer doing so before a package leaves `0.0.x`, since that is the last cheap moment to fix a shape. |

Describe the 0.0.x rule as project policy.
Cargo and npm apply different compatibility ranges to 0.0.x versions. Replace the package-manager rationale in CONTRIBUTING.md and CLAUDE.md with: “This project makes no compatibility promise for 0.0.x packages.”

Include unpublished and private packages in the final shortcut.
Line 16 sends publish = false and private packages to main, but this line sends every non-0.0.x package to dev. Those instructions conflict for an unpublished or private package with another version.

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
