Tom Boucher fdd5e401eb feat(architecture): [EoS/claude] drive claude through the imperative adapter + descriptor-driven hostBehaviors (#2086)
Fold Claude Code's install/uninstall onto the Embeddable Orchestration System
(ADR-1239 Phase D). claude is GSD's tier-1 reference host, but its install path
was still driven by 13 hardcoded `runtime === 'claude'` string-equality branches
scattered across bin/install.js rather than the public Host-Integration Interface.

- Route install()/uninstall() through `createImperativeAdapter({runtime})` — the
  adapter delegates to the SAME installRuntimeArtifacts/uninstallRuntimeArtifacts
  engine calls, so output is byte-identical (proven pre/post, both scopes).
- Replace all 13 `runtime === 'claude'` / `runtime !== 'claude'` branches with
  descriptor-driven `runtime.hostBehaviors` lookups on capabilities/claude/
  capability.json (attributionSource, authorsCanonicalWorkflow, localInstallStyle,
  permissionsSchema, settingsFileByScope, sourceMarkerFile, agentFrontmatterExtensions,
  ownsClaudePaths, nativeModelAliases, skillsGlobalOnboarding). Behavior is
  identical; the brittle string-equality coupling (the add-a-host tax) is gone.
- Single-source the scattered literal 'claude' defaults/rosters behind DEFAULT_RUNTIME.
- Extend golden-install-parity to assert the claude LOCAL legacy layout is
  byte-identical too (AC1 "both scopes"); exclude the platform-varying
  settings.local.json (same reason settings.json is excluded).
- New tests/claude-imperative-reference.test.cjs: adapter kind, programmatic-cli
  profile, fail-closed negotiation on a corrupted/partial descriptor, and an AC2
  source guard that no `runtime === 'claude'` branch remains.

No user-visible install-output change (internal architecture only).

Changeset Fragments

This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.

Why

Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.

See #2975 for the full rationale.

Adding a fragment

node scripts/changeset/new.cjs \
  --type Fixed \
  --pr 1234 \
  --body "fix the thing — explain the user-visible change in one sentence"

This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.

Format

---
type: Fixed
pr: 1234
---
**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.

Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.

Opting out

PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.

At release time

Promotion is automatic. The release workflow's finalize job runs:

node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD --allow-empty

This reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, and deletes consumed fragments. The --allow-empty flag ensures a no-change release still gets a dated heading (with a _No notable changes._ placeholder). A subsequent verify step confirms the promotion landed correctly. Maintainers do not run this by hand.

Archived fragments

.changeset/archived/ holds fragments for already-shipped releases (≤ 1.3.1), retained for provenance. Their content was hand-curated into the dated ## [1.x.y] sections of CHANGELOG.md during the #690 backfill — they were never consumed by render. All changeset tooling enumerates .changeset/ non-recursively, so archived fragments are never picked up or rendered. Do not move them back to the top level.
