Finishes quest/m3/release/cycle-phases.md.

Problem

A cut waits for every breaking change, so it grows large (main was 3,190 commits ahead of release on 2026-11-09), and a deployment that follows release can only take all of it. The maintainer decided (2026-11-09) that after the next cut each cycle runs additive work, then API breaks, then wire changes, with main cut on demand in the first two phases and patch versions while the cycle is additive. Nothing in the repo described or enforced that.

Approach

• RELEASE.md (Releases, Versions; main moved them out of CONTRIBUTING.md): the three phases, what an API break and a wire change are, how the maintainer opens a phase, and the two kinds of cut. An additive cut publishes patches and runs only the readiness checks. An API or wire cut advances the shared minor with just version, and also needs the migration audit and the API shape, feature, and Cargo feature reviews. The release-to-main merge now comes before every cut, not only breaking ones.
• version.json gets a phase field (null, additive, api, or wire). just version rejects any other value. It stays null until the 0.22.0 cut, the same way minor does.
• Phase reset after a breaking cut: the 0.22.0 cut and each wire cut keep their old phase in the cut PR, so its API diff only reports; a PR on main sets phase to additive once the cut has merged into release.
• Enforcement: while phase is additive, the cut PR's API diff runs with --deny, and a new Nightly job runs just api-diff --deny on main. In any other phase that Nightly job skips before the nix setup. Backports still deny, and release's missing version.json counts as null.
• Questline (quest/README.md, quest/m3/README.md): the phase definitions and the milestone layout after the next cut. m1 is additive work, m2 API breaks, m3 wire changes, m4 and m5 later work, and m6 the deferred bucket. The re-split at the next cut and the shift at each cycle-ending cut are both spelled out.
• Cut recurrence (quest/m3/release/cut.md): the cut now recurs per cut. Each cut re-creates itself with no Required and a maintainer ## Waiting item naming the next cut's kind. A breaking cut first re-creates the three reviews and the migration audit as its Required. Each cut re-creates its successor, and a breaking cut its reviews, in m0's release epic, so the wire cut can require m2 and m3 without requiring itself. A wire cut sets phase back to additive and shifts the milestones. The cut gate moves to m3.
• API diff rule (sh/api-diff/run.sh): an added optional TypeScript property (name?: T, including a multi-line inline type whose closing bracket lines up with it) now counts as an addition, not a break, since no caller must pass it. The old rule flagged every line added inside an existing declaration; that was harmless while the diff only reported, but the additive phase's --deny would refuse ordinary additive work.
• Workflows: .github/workflows/nightly.yml calls api-diff.yml with secrets: inherit, and the api-diff job gets the cache-write environment so Nightly can write its cache.
• The review quests and the migration audit say they recur once per API or wire cut. This quest's file and its links are deleted.

Choices made without asking

• Hang catalog JSON and stored or exported container formats are wire changes. A deployed peer parses them without rebuilding. A change to an unpublished -wip version also counts as wire work.
• Enforcement runs nightly, not per PR. CI is moving expensive checks off main PRs (m0 CI cost), and cargo-semver-checks documents every crate twice. A daily signal catches an early break within a day for one run per day. I rejected just api-diff --deny in the merge queue (the job has a 120-minute timeout and would serialize the queue) and a check on the ! in PR titles (Check never blocks, and it misses unmarked breaks).
• Wire ordering relies on planning alone. No cheap check tells a wire change from other work across the many drafts and both languages. Wire work waits in m3 until the maintainer opens the wire phase, and the wire cut finalizes the wire version.
• JS packages and binding wrappers take a patch at an additive cut by a manual bump on main before the cut PR. That matches today's backports. Go derives its patch in CI, and the FFI packages follow their Rust crate through release-plz.
• phase is edited by hand, not by just version. An API cut advances the minor but keeps the api phase, so the recipe can't infer the phase. The 0.22.0 cut and each wire cut set it to additive. The maintainer opens the api and wire phases with their own PRs.
• The re-created cut and its reviews live in m0's release epic, not m3. The 0.22.0 cut already moves the remaining release execution to m0, and a wire cut inside m3 that requires m3 would wait on itself (the last review's open finding).
• Milestones move down one, adding m6. The quest said "today's later-work milestones moving down one". The next cut's re-split therefore keeps m4, empties m5, and moves today's m5 to m6.

Impact

• Public API: none. Wire: none.
• version.json gains "phase": null. sh/version.py now requires the key.
• The published version numbers change shape after 0.22.0: fewer shared minors, more patches.
• CI: Nightly gains an api-diff job (in the cache-write environment) that is a no-op until phase is additive.
• just api-diff no longer reports an added optional TypeScript property as breaking.

Alternatives

• Order the phases by Required between milestones. An epic's Required doesn't block its children in quest unblocked (checked on quest/m3/release/). Additive work is also perpetual, so m2 requiring m1 would never unblock.
• Re-create the reviews every cycle in m2. With on-demand API cuts, a cycle can have several breaking cuts, and each one needs its own reviews.

Follow-ups

None recommended.

Validation

• Exercised the API diff's mode step from .github/workflows/api-diff.yml under bash for every phase (null, additive, api, wire, and no version.json) against Nightly, the cut PR, a fork's main, and a backport: Nightly denies only in additive and skips otherwise; the cut reports unless additive; forks and backports always deny.
• Fed breaks() in sh/api-diff/run.sh full-context diffs: an added optional TS property (single-line and multi-line inline object) is an addition; an added required property, a changed line, and an added C struct field still break.
• quest review --harness codex round 3 on c77ecb3: 10/10, no findings.
• python3 sh/version.test.py: 7 tests passed, including the phase accept and reject cases.
• just check (biome, markdown, gh including actionlint and zizmor, gh tests, quest, shell): passed after merging main.
• quest check and quest check --base origin/main: 504 documents ok.

Stopping this claim: the maintainer scoped this spawn to m0-m2, and this m3 quest was started by mistake. The work so far (the phase rewrite in fa3c02db9e) stays on this draft for the maintainer to pick up or close; nothing more is being pushed.

Walkthrough

The version configuration now includes a validated release phase. The API-diff workflow selects report-only, deny, or skip behavior based on the event, pull-request source, and phase; Nightly invokes that workflow. The API-diff check recognizes optional TypeScript properties as an exception to its breaking-change classification. Release and quest documents describe phase-specific cuts, milestone changes, and recurring review procedures.

Merge Risk: Low · up to c77ec

This PR adds release phases and phase-dependent API-diff enforcement. The remaining problems are in the release-cut documentation: the phase reset should wait for the FFI release archives, and C++ patch cuts should include an OBS version bump. Both could cause a failed Nightly run or a refused OBS release during a cut, and both are easy to fix before merging.

Explanation

The title names the main change: release cycles move through phases by change kind, and cuts happen on demand. It matches the RELEASE.md, version.json phase field, quest, and API-diff changes. Its scope is broad, but it is not off-topic. It also uses the conventional-commit prefix and stays under one line.

Full details: Description check

Explanation

The description states the problem, approach, enforcement, validation, and impact of the change. It matches the changeset: RELEASE.md phases, version.json phase field, sh/version.py validation, the Nightly api-diff job, the API-diff optional-property rule, and the quest files. It is detailed and on-topic.

ℹ️ No critical issues — one sequencing gap in the phase reset, inline.

Reviewed changes

I reviewed the whole PR at 6afedec: the phase field and its check, the API-diff mode selection, the new Nightly job, and the rewritten release and questline procedures.

• version.json phase: a new key that sh/version.py checks against null, additive, api, or wire, with tests for accepted and rejected values.
• API-diff mode step: Nightly denies only while the cycle is additive and skips the nix setup otherwise. The cut PR only reports unless the cycle is additive. Backports and a fork's main always deny.
• Nightly api-diff job: calls the reusable workflow with secrets: inherit, the same way release-gate.yml does.
• RELEASE.md: the three phases, what counts as an API break and as a wire change, the additive and API/wire cut kinds, and the release-to-main merge now runs before every cut.
• Questline and cut recurrence: m1 holds additive work, m2 API breaks, and m3 wire changes, with m6 as the new deferred bucket. The cut now recurs per cut in m0's release epic. The reviews and the migration audit recur once per API or wire cut, and cycle-phases.md is deleted.

Reviewed changes

I reviewed the delta since 6afedec, which is docs-only wording in two files.

• Phase reset waits for publication: RELEASE.md now sets phase back to additive only after the cut has merged into release and every package it bumps is published, since the API diff's baselines are the published versions.
• Matching cut procedure: quest/m3/release/cut.md applies the same condition in the 0.22.0 paragraph and the Wire bullet.

My earlier thread on this sequencing gap is resolved.

Reviewed changes

I reviewed the delta since 8c56205, which touches the API-diff workflow and its break detector.

• Cache-write environment: the diff job in api-diff.yml uses the cache-write environment only on main refs, so Nightly's run can write the Rust cache and PR runs are unaffected.
• Optional TS properties are additions: breaks() in sh/api-diff/run.sh no longer counts an added name?: T line inside an existing declaration as a break.
• Closing brackets: a closing bracket that lines up with an added line, such as an optional property's inline object type, is no longer a break.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Do not classify every optional property as compatible.

For a union { foo: string } | { bar: string }, existing consumers can use "foo" in value to narrow value.foo to string. Adding foo?: number to the second variant makes that expression string | number | undefined, so those consumers no longer compile. This check reports the addition as non-breaking and allows it through additive cuts and backports. Classify optional additions as breaks unless compatibility is established.

Wait for the FFI release archives before resetting the phase.

The reset step waits only for release-plz. The FFI API diff compares against the published moq-c and moq-ffi release archives. If the cut's FFI archives are not yet published when phase changes to additive, the FFI diff can compare against the previous archive. Every break the cut ships then appears as a break, and Nightly's --deny run on main can fail.

The JS diff does not use npm. Its baseline is rendered from the source of release, so npm publication does not affect it.

Add the OBS version bump to additive cuts that publish C++.

Line 72 says each C++ release also cuts obs-moq-v<version>, and the release refuses a version that an earlier release already used. The additive procedure does not name an OBS step. If it publishes a C++ patch, the OBS release can fail even when OBS code did not change.
