Mechanical rename produced by scripts/msd-rename.cjs: gsd/Gsd/GSD -> msd/Msd/MSD across contents and paths, upstream package/repo coordinates -> @golem15/msd-core and golem15com/msd-core. Deep links into upstream history, sibling upstream packages, the GSD-2 import feature, CHANGELOG.md and .changeset/ are kept as-is. Hand edits on top: MSD block-letter banner and logos, LICENSE copyright line, package/plugin identity, regenerated lockfile, install-tree fixtures, derived registries and benchmark baseline; migration checksum baseline re-locked (MSD keeps its own install state, so no install had applied the old sums); sort-order and regex-escaped expectations in tests adjusted.

Canary Stream
The canary dist-tag is MSD's earliest preview channel. It exists so contributors and willing early adopters can exercise in-flight features against the long-lived dev integration branch before they have any expectation of stability.
Stream policy
MSD ships through three npm dist-tags, each fed by exactly one git branch. Streams do not mix.
| Branch | dist-tag | Audience | Stability |
|---|---|---|---|
dev |
canary |
Contributors, willing early adopters | Best-effort. May regress between cuts. Roll-forward only. |
main |
next |
Maintainers, RC testers | Release-candidate quality. Bug-bar enforced. |
main |
latest |
Everyone else | Production stable. The default npm install target. |
dev is the integration branch for in-flight feature work (typically multi-PR vertical slices like the MVP/TDD/UAT track in 1.50.0). When the dev work stabilizes, it promotes to main as an RC train (vX.Y.Z-rc.N published to next), and after the RC train bakes, the same train promotes again to latest.
A canary build NEVER becomes a next build directly, and a next build NEVER becomes a latest build directly — every promotion goes through a fresh tag and a fresh release.
Installing canary
# One-off invocation (npx)
npx @golem15/msd-core@canary
# Pin to the canary dist-tag globally
npm install -g @golem15/msd-core@canary
# Pin to an exact canary version
npm install -g @golem15/msd-core@1.50.0-canary.1
The CC installer's defensive purge rewrites stale config blocks left by older MSD versions, so reinstalling on top of an existing project is safe.
When to install canary
✅ Do install canary when you want to:
- Exercise in-flight planning/execution/verification features early and report findings
- Validate a fix you've contributed to
devis reachable end-to-end - Help shake out canary-bake items (rough edges that won't ship to
nextuntil resolved)
❌ Do NOT install canary on:
- Production projects you depend on for delivery
- A machine where rolling back means recreating MSD state (use a profile or a workspace instead)
- A demo or onboarding setup — pin to
@latestso audiences see the stable surface
Rolling back from canary
# Back to the current stable
npm install -g @golem15/msd-core@latest
# Or to the next/RC train
npm install -g @golem15/msd-core@next
If you have a local project that interacted with canary-only features (for instance, an MVP-mode phase planned by 1.50.0-canary), the planner artifacts in .planning/ remain valid — older MSD versions will just ignore the **Mode:** mvp field on phases.
Reporting issues against canary
File against the issue tracker with the bug template. Include the exact canary version (msd-core --version reports it) so triage can route the report back into the dev stream rather than the stable stream.

CHANGELOG.md - Stream architecture rationale: discussed across #2727, #2773 (codex schema-break and the resulting promotion bottleneck that motivated explicit stream isolation)
