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

Architecture Decision Records
This directory contains Architecture Decision Records (ADRs) for GSD.
Each ADR documents one architectural decision: what was decided, why, and what consequences follow. ADRs are append-only. Amendments extend existing ADRs with a dated section rather than replacing them.
Naming Convention
New ADRs use issue#-prefix slug naming:
docs/adr/<issue#>-<kebab-slug>.md
Examples: 3485-adr-prd-naming-convention.md, 3464-review-default-reviewers.md.
Why
Two developers computing "next ADR number" locally against main will independently pick the same integer and both ship. The collision is already on disk — 0010-* exists twice and 0011-* exists three times. GitHub issue numbers are server-assigned and atomic: the moment you open an issue, that number is reserved globally. Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — two PRs that each use a distinct issue# as their ADR prefix never collide. Same shape, same solution.
Legacy ADRs
Files 0001-* through 0011-* are preserved as immutable historical record. The duplicate 0010-* and the three-way 0011-* are documented residue of the old local-compute convention — not patterns to imitate. Do not renumber them.
Full process
See CONTRIBUTING.md — "Proposing an ADR or PRD" for the end-to-end workflow: opening the issue, waiting for approval, naming the file, and submitting the PR.

Seam map
ADR 0005 is the top-level SDK seam index. It references per-seam ADRs and states the narrow-waist principle each seam follows. Use it as the entry point for understanding SDK module ownership.
ADR 0006 documents how SDK query handlers project planning paths (cwd → effectiveRoot → .planning/<project>/...). Cross-reference with the Planning Workspace Module (ADR 0004) for workstream pointer policy.
ADR 0008 documents the Installer Migration Module for safe install-time moves, removals, config rewrites, and user-data preservation.
ADR 0009 documents the Shell Command Projection Module seam for runtime-aware projection of installer-owned command text and projection IR.
ADR 0010 documents the File Operation Engine Module seam for converging installer/migration/planning file mutation safety policy, and its relationship to ADR 0009 hook-command ownership policy.
ADR 0011 documents the Skill Surface Budget Module for install-time skill/agent
profile staging (--profile=<name>, .gsd-profile marker, requires: closure)
and the Phase 2 runtime /gsd:surface command for cluster-level enable/disable
without reinstall.
