* test(#2845): failing-first suite for UI-SPEC inventory provenance Binds two shared formats before either exists, so the suite is RED against next: the gsd-ui-checker dimension roster (asserted independently on twelve surfaces, eight English and four translated) and the provenance-line grammar the UI-SPEC template emits and Dimension 7 consumes. Every parity assertion is paired with a synthetic mutation case, so the guard's failure branch executes rather than only reading a correct tree: limit-1 (a surface still declaring 6), limit (7), limit+1 (8), a dropped dimension, a label that drifts on one surface only, a non-contiguous roster, a duplicated number, and a surface that stops declaring a count at all. A seeded fast-check property renders the roster under formatting noise (CRLF, padding, interleaved sections) and asserts the parse round-trips and is strictly sensitive to a dropped heading. Assertions are on parsed typed records, never raw substrings. * docs: normalize design-a-ui-phase how-to to American English House style for docs/ is American English (CLAUDE.md). This file carried colour/initialisation/initialise/artefact throughout. Spelling only — no content change; kept separate from the #2845 feature commit so the release-notes classifier and the hotfix cherry-pick filter see it for what it is. * feat(#2845): require provenance for UI-SPEC component inventories A UI-SPEC's component inventory was treated downstream as a closed allowlist while the document recorded nothing about whether the list had been enumerated from the installed design system or recalled from memory. A recalled inventory is indistinguishable from an enumerated one, so an executor complying with the spec builds against a fraction of what the package offers, and every gate stays green because they assert semantics rather than composition. The UI-SPEC template gains a Component Inventory slot carrying one of two provenance lines: the command that enumerated the list, the count it returned, the resolved package@version and the date; or a Could not enumerate record with a real reason. gsd-ui-researcher gains an enumeration ladder and must record the line rather than write the list from recall. gsd-ui-checker gains Dimension 7. An inventory with no provenance line, a count with no command, an empty could-not-enumerate reason, or a line still carrying the template's unfilled placeholders BLOCKs; a partial line, a line placed below its table, or an honest negative record FLAGs; a complete line passes, and so does a spec carrying no inventory at all, which keeps every UI-SPEC predating the dimension validating unchanged. Whatever the verdict, an unsourced inventory is reported as a non-exhaustive list of known-good components rather than a closed allowlist, so the executor is never blocked from a component the spec merely failed to mention. The checker never runs the recorded command. The dimension count moved on all thirteen surfaces that assert it, across five languages. Also corrects the claim in the English, Korean and Portuguese how-tos that this checker applies a scored six-pillar rubric — that rubric belongs to /gsd-ui-review's retroactive audit. * chore(#2845): backfill changeset pr number to 3745 --------- Co-authored-by: sim <sim@local>
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
- Probe edges in a non-English project — get real edge coverage on a spec written in another language, and tell "no edges here" apart from "the probe could not read it"
- Resolve prohibition findings — turn the spec phase's surfaced must-NOT constraints into resolved, dismissed, or deferred spec decisions
- Resolve an unreachable-workflow finding — wire or fully sweep a shipped workflow that no command, agent, or skill references
- Resolve verify-command path findings — fix an
<automated>verify command whose target directory does not resolve from the executor's cwd - Resolve a contract-drift finding — bring an agent's completion contract, read-tag gate, or deleted-file test reference back into agreement with the registry
- Resolve unreachable-guard findings — fix shell guards whose fallback arm cannot run, and tell "nothing to report" apart from "could not look"
- Resolve an ESLint glob-coverage finding — bring a source file that matches no lint rule under coverage, or record a reasoned exemption
- Read the statusline freshness marker — turn on
state ~N commits back, and tell "STATE.md is fresh" apart from "freshness could not be established" - Consume the planning snapshot — read
planning inspectfrom a dashboard or harness, and tell "nothing to report" apart from "could not look" - Keep planning docs out of a shared repo — make
.planning/local-only, including untracking files git already tracks (the step.gitignorealone cannot do) - Publish PRs without planning artifacts — keep
.planning/committed locally, so worktrees and/gsd-undokeep working, whileplanning.pr_strictkeeps every planning path out of the branch you push - Plan a phase — run research, decompose work, and verify plan quality
- Verify a dependency-compatibility claim — act on a compatibility claim the researcher left
[ASSUMED], and tell "nothing declared" apart from "a constraint is declared" and "the lookup failed" - 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
- Catch complexity before it compounds — enable the post-execute refactor hook, read a proposal's score vs. anchor delta, and accept or decline it
- 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
- Control which host runtime GSD reports — read the
agent_runtimeladder, understand what host detection looks at, and pin the runtime when detection is not what you want - Set up cross-AI review — configure a second AI to review code produced by the primary agent
- Scope code review depth by path — escalate
/gsd-code-reviewtodeepfor sensitive directories while the rest of the repo stays at the default depth - 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
- Interpret scope-conformance warnings — read the advisory the worktree-wave merge emits when a plan branch commits outside its declared scope
- Interpret install-shadow warnings — read the advisory GSD Core emits when a
/gsd-*trigger is installed at both scopes and one silently wins, and tell "nothing to report" apart from "could not look" - Interpret
state validateresults — read thescopereason codes and tell "nothing to report" apart from "could not look" - 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
- Enable live-DOM verification — opt a project into browser-backed UI acceptance checks during execution, handle the browser-profile lock, and tell "nothing to report" apart from "could not look"
- Develop a Capability for GSD 1.5+ — add feature Capabilities, hook fragments, and registry entries
- Ship a reviewer lane in your capability — declare a
reviewerbody so/gsd-reviewdiscovers, invokes, and renders your external review CLI or model endpoint - List your reviewer lane in the registry — publish a lane you have built to the Reviewer Lane Registry so other people can find and install it
- Take over a capability or EoS integration — assume maintainership of an existing third-party capability, reviewer lane, or EoS host integration through a handoff, an adoption fork, first-party absorption, or a de-listing
