* docs(#2793): add ADR-2782 — reviewer lane capability surface Design lock for epic #2782. Declares a reviewer lane as capability data rather than a core patch across three unrelated surfaces. Key decisions: - D2 transport discriminator (spawn | openai-http) — a survey of all twelve lanes found three that are HTTP endpoints with no binary, which invalidated the single-invoke-shape draft. - D4 the reviewer body is optional and absent-safe at every layer. - D5 a fourth executable-surface disclosure class covering the lane binary or host AND its egress payload classes. - D6 handler is a closed first-party enum, upholding ADR-1016; the consequence — third-party lanes are data-only — is stated plainly. - D7 probe kinds wider than existence, and every probe bounded. Amends ADR-857, ADR-894, ADR-1016, ADR-1244. Also records the D7/D8-extended-by-ADR-1244 marker on ADR-857 that ADR-1244 D8 promised but never added. Closes #2793 * docs(#2793): address orthogonal review findings on ADR-2782 Two blockers from the isolated adversarial pass: - D5 disclosed the spawn binary but not its args, reopening the #1459 bug class already fixed for MCP servers (binary python3 + args -c <program>). args are now disclosed and signature-bound. - hostConfigKey resolves from .planning/config.json, which is mutable after consent with no integrity check, so a lane consented against localhost could be silently redirected to a remote host by an ordinary PR. The resolved host is now consent-bound and re-verified on the invocation path; a mismatch blocks the lane. Majors and spec gaps: - D4 gains an explicit-selection carve-out. Absent-safe governs discovery, never a lane the user named; the current selector records that as info, which Phase 1 now corrects. - D4 gains a warning delivery channel. - D6 enumerates the handler closed-enum members; a closed enum whose membership is left to the implementing phase is not closed. - D6 records aider and plandex as concrete lanes the vocabulary cannot express, rather than claiming sufficiency it did not verify. - D2 gains evidenceClass, requiresBinaries, promptBudgetKey for per-lane divergence that was only prose, and motivates the one-member outputChannel enum. - reviewer.requires renamed requiresBinaries — it collided with the envelope requires (capability deps) at a different nesting depth. - Antigravity two-level timeout: Context cited it then dropped it; now explicitly delegated to the handler. - D9 gains a per-key ownership table, including three keys that stay central because they are policy across lanes, not lane properties. - Phase table maps every decision D1-D9 to a delivering phase; D6 handler modules and D5 invocation-time re-verification were previously unclaimed. - American English per house style.
GSD Core documentation
Documentation is organised into four quadrants: tutorials help you learn by doing, how-to guides solve specific tasks, reference states authoritative facts, and explanation explores concepts and design decisions.

Tutorials
- Your first project — install to first shipped phase, one guaranteed path
- Onboarding an existing codebase — bring GSD Core to a brownfield repo
- Build your first capability — author a tiny declarative capability and watch it act in the loop
- Install your first capability — install a third-party capability end-to-end: consent, verify, check for updates, remove
How-to guides
- Install on your runtime — runtime-specific install steps for all 16 supported runtimes
- Install a minimal GSD and add skills later — install only the core skills, then grow the surface with profiles and
/gsd:surface - Attach a plugin-provided skill to a GSD agent — use the
global:plugin:skillentry form to load Claude Code plugin skills into agent prompts - Discuss a phase — capture implementation decisions before planning begins
- Resolve edge-coverage findings — turn the spec phase's surfaced domain-boundary edges into covered, dismissed, or backstopped spec decisions
- Resolve prohibition findings — turn the spec phase's surfaced must-NOT constraints into resolved, dismissed, or deferred spec decisions
- Plan a phase — run research, decompose work, and verify plan quality
- Execute a phase — run plans in parallel waves with fresh-context subagents
- Verify and ship — walk through completed work, diagnose failures, and create the PR
- Run phases autonomously — use autonomous mode for unattended phase execution
- Handle quick and fast tasks — use
/gsd-quickand/gsd-fastfor ad-hoc work outside the phase loop - Configure model profiles — switch between quality, balanced, and budget model tiers
- Set up cross-AI review — configure a second AI to review code produced by the primary agent
- Work in parallel with workstreams — run independent lines of work simultaneously using workstreams
- Isolate work with workspaces — use workspaces to sandbox experimental or risky changes
- Debug a failed execution — diagnose and recover from broken or incomplete phase execution
- Spike and sketch — use
/gsd-spikeand/gsd-sketchfor exploratory work before committing to a plan - Design a UI phase — use the UI phase loop for frontend and visual work
- Develop a Capability for GSD 1.5+ — add feature Capabilities, hook fragments, and registry entries
- Add or update a host's integration — set a host's documentation-sourced
runtime.hostIntegrationaxes (ADR-1239 Phase A), with theundocumentedsentinel rule - Turn a capability off (and keep it off) — disable a capability via the surface, or gate individual hooks off without removing the capability
- Drive GSD from a tracker issue — start a phase from a GitHub, Linear, or Jira issue
- Migrate from GSD 2 — upgrade an existing GSD 2 project to GSD Core
- Update GSD — re-run the installer to pick up the latest release
- Clean up get-shit-done-cc — remove leftover old-package artifacts that cause a spurious
⬆ /gsd:updateindicator after migrating to@opengsd/gsd-core - Fix the worktree base-mismatch (exit 42) error — resolve the branch-divergence condition that halts parallel phase execution
- Recover and troubleshoot — fix common problems, rebuild context, and uninstall

Explanation
- Context engineering — how context rot forms and how GSD Core prevents it
- The phase loop — design rationale for the Discuss → Plan → Execute → Verify → Ship cycle
- Multi-agent orchestration — how subagents are spawned, scoped, and coordinated
- Security model — trust boundaries, permissions, and safe automation
- The capability trust model — why third-party capabilities are gated by consent + integrity + reversibility, not a sandbox
- How overlay capabilities compose — why first-party always wins and how the loader resolves precedence, conflicts, and fail-open load-failure warnings
- Architecture — system architecture, agent model, and data flow
- The Embeddable Orchestration System — one public, versioned contract for embedding GSD across many hosts
- Discuss modes — assumptions mode vs interview mode for
/gsd-discuss-phase - Context monitoring — context window monitoring hook architecture
- Issue-driven orchestration — recipe for driving GSD from a tracker issue using existing primitives
