* docs(#2674): amend adr-1411 with the corrupt-is-not-absent house pattern ADR-1411 reasons only about a resolution miss. It is silent on input that is present but not usable, which is how five engine read paths (#1879) could fold an unusable input into the value meaning 'genuinely absent' without contradicting an Accepted ADR. Read together, ADR-1411 and ADR-227 converge and do not license throwing as the cluster's answer: ADR-227 requires malformed input to be coerced rather than propagated and carves out only genuinely-fatal fields, while ADR-1411 already permits a fallback provided it is 'a visible value, not a silent substitution'. The defect in these five sites is therefore not that they fall back but that they fall back invisibly. Records the pattern that follows: every current return value is preserved, and the cause is made visible in-band where the result already carries a provenance envelope, or out-of-band via a deduplicated stderr diagnostic where it returns a bare value it cannot extend. Throwing stays confined to ADR-227's genuinely-fatal carve-out, decided per call. Also names the per-applier caller audit and the lint-resolution-provenance registry gap. Refs #1879 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#2674): prove the warning-state reset misses the unknown-key dedup set The two existing cases in this suite only pass because each picks a key name no other case reuses, so neither can observe whether the reset the beforeEach calls actually runs. Failing-first: asserts the exported _warnedUnknownConfigKeys is empty after _resetRuntimeWarningCacheForTests(). It is not - the helper clears only _warnedConfigKeys despite documenting itself as resetting per-process warning state. Refs #1879 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2674): reset the unknown-key dedup set with the runtime warning cache _resetRuntimeWarningCacheForTests documents itself as resetting per-process warning state but cleared only _warnedConfigKeys, leaving _warnedUnknownConfigKeys populated across cases. The suite that exists to test that set - 'loadConfig - unknown-key warning dedup' - calls the helper in beforeEach expecting exactly this, so the reset was a silent no-op for it; both cases passed only because each picked a key name the other never reused. Any later case reusing a key would have had its warning suppressed by leaked state. Found while amending ADR-1411, which names this dedup guard as the pattern five downstream PRs (#1880-#1884) will adopt - shipping the ADR without the fix would have propagated the footgun to each of them. Folded in here per CLAUDE.md's no-defer rule rather than filed. RED verified on 3c4895841 (test only, no fix): linux-node22 reported 'FAIL tests/config-loader.test.cjs - the documented per-process warning-state reset must clear the unknown-key dedup set too'. Refs #1879 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#2674): document src/ in the changeset-lint trigger list CONTRIBUTING.md presented the Changeset Required trigger list as bin/, gsd-core/, agents/, commands/, hooks/, sdk/src/ - omitting src/, which scripts/changeset/lint.cjs has in USER_FACING_PREFIXES. src/ is the TypeScript source of truth compiled into gsd-core/bin/lib/*.cjs, so it is the most-edited user-facing path in the repo and the omission sends any contributor who touches it into a CI failure the doc says cannot happen. Also documents that the lint reads GITHUB_BASE_REF, which only CI sets, so running it bare locally reports success without evaluating the branch. This PR hit exactly that: a local run said ok_fragment_present and CI failed fail_missing_fragment on the same diff. Found while opening this PR; folded in per the no-defer rule. Refs #1879 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#2674): add Fixed changeset for the src/ trigger-list and reset fixes Refs #1879 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#2674): restore the round-2 review corrections to the amendment These edits were made in response to the second isolated review pass but never staged: later commits used targeted `git add <file>` for the test and the source fix, so the two markdown files stayed dirty and shipped nothing. The branch carried the round-1 text, including the ADR-227 misquote the reviewer raised as a blocker. Restores: the unconditional-diagnostic clause (ADR-227's GSD_DEBUG opt-in was never implemented, so citing it as the precedent was wrong), the dedup key, #1882 folded into the out-of-band mechanism instead of a fourth mechanism-less category, the narrowed caller-audit rationale, and the test-methodology clause.

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.
Language versions: English · Português (pt-BR) · 日本語 · 简体中文
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

- 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
