* feat(#1684): add negotiated host-integration interface module ADR-1239 Phase A: a pure, additive, no-I/O module exposing PROTOCOL_VERSION, the 8-axis HOST_INTEGRATION_AXES closed vocabulary, the UNDOCUMENTED fail-closed sentinel, negotiateHostCapabilities (effective subset of host-declared and engine-known), a typed degradation ladder, and host-capability profiles. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * feat(#1684): validate and document host-integration axes (16 runtimes) Extend validateRuntimeBody to validate the 8 hostIntegration axes (closed enums + undocumented sentinel + dispatch struct + reserved-key guards) and the widened runtime vocabulary; author a documentation-sourced hostIntegration block in all 16 runtime descriptors; regenerate the registry. Every per-CLI value is documented (cited) or the explicit undocumented sentinel. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs(#1684): add host-integration capability matrix and adr amendment New per-CLI, per-axis citation reference (value/source/evidence for all 16 CLIs); ADR-1239 Phase-A-implemented amendment; CONTEXT.md glossary seam entry. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#1684): harden dispatch negotiation edge cases Code-review hardening: treat NaN/Infinity maxDepth as missing (fail-closed, +warning); reset nested/background when namedDispatch collapses to false (struct consistency); SAFE_DEFAULTS dispatch floor to read-only; warn on non-finite protocolVersion; symmetric undocumented warnings for dispatch fields. Pure module — no consumers; behaviour fail-closed throughout. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * chore(#1684): register host-integration.cjs in lint-ignore and inventory New tsc-generated bin/lib artifact: add to the eslint ignore list (ADR-457 — lint the .cts source), regenerate docs/INVENTORY-MANIFEST.json, and add the docs/INVENTORY.md CLI-modules row. Fixes the 3 gsd-test failures (551-eslint-bin-lib-coverage x2 + inventory-manifest-sync). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs(#1684): add changeset fragment for host-integration interface Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs(#1684): add how-to for sourcing a host's integration axes Diataxis how-to guide for adding/updating a host's runtime.hostIntegration axes from authoritative docs, the undocumented-sentinel rule, validation, and extending the closed vocabulary. Completes the Step-5 doc quadrants (reference + explanation + how-to). Indexed in docs/README.md.

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.
ADR 1411 establishes the Resolution Provenance principle: context resolution (config loading, project-root anchoring, workstream resolution) must report its provenance rather than fall open silently to defaults. It is the resolution-side analog of ADR 227 (input-validation shape), binds the Config Loader Module, Project-Root Resolution Module, and I/O Module, and is the decision record for epic #1411 (phases P1–P4).
