Author capabilities/<runtime>/capability.json for all 16 runtimes (role:runtime),
populating the registry's runtimes index ({} -> 16). Each carries the 6 ADR-1016
axes (configHome structured, configFormat, artifactLayout structured, commandStyle,
hooksSurface + hookEvents, sandboxTier, supportTier), extracted from the live
modules (runtime-homes/runtime-slash/runtime-artifact-layout/runtime-config-adapter
+ CODEX_AGENT_SANDBOX). validateRuntimeBody tightened to enforce the closed
vocabularies + structured configHome/artifactLayout (rejects old string configHome;
env required; skillsHome recursively validated).
Registry-only: bin/install.js + src/*.cts untouched, zero behavior change. The 5b-5f
drive steps consume these one axis at a time (ADR-1016 §8).
Codex accuracy review caught + fixed: opencode/kilo register ZERO lifecycle hooks
(install.js skips the whole block) -> hooksSurface:none (configFormat stays
settings-json); kimi probe selects on <root>/skills existence -> probeExists:"skills".
ArtifactKind required-field strictness + ConverterName closing deferred to 5d/5e.
ADR-1016 (Proposed) amended to match (Decisions 1 + 5).
Closes#1035

Realize ADR-857 Branch 8 (host-CLI support as role:runtime Capabilities) +
materialize ADR-58's InstallPlan. Closes the 6-axis descriptor vocabulary,
absorbs the hard-case runtimes as data, and stages the install migration as a
5a→5g ladder (4/6 axes already modularized; InstallPlan is the 5g capstone,
reachable by collection, not a big-bang rewrite).
Amended after a plugin-side design grill (rubber-duck + grill-with-docs vs
#956 MemPalace / #999 Impeccable):
- New term Connected Capability (CONTEXT.md) — a Capability whose integration
shape brings its own external process/service/state; orthogonal to authorship.
Named, tracked gap (vehicle #956); current schema does not express it.
- Narrowed the dogfood claim: the descriptor dogfoods the runtime interface
only, not the feature-plugin/Connected path.
- Structural "off means off" rule (CONTEXT.md RULESET.CAPABILITY.off-means-off):
the host derives shared outputs from active hooks; a hook adds/is-counted,
never mutates host source. Ratify in ADR-894; proven by spike #1018.
- Hand-waves resolved by code: sandboxTier real-but-thin; model-catalog
orthogonal (not a 7th axis); converters closed into a ConverterName enum +
added the kimi-agents artifact kind; configHome is pure read-only.
- Hook-firing path is unproven (render-hooks built, never consumed) → spike
#1018 must prove render-hooks→live-workflow execution before phase-5 build.
Design-only; no code. Status: Proposed.
Closes#1016
