Tom Boucher 14679b866b enhance(#2856): add default-off live-DOM UAT capability (#3716)
* test(#2856): add failing-first suite for the live-dom-uat capability

Binds the approved triage shape before any of it exists:

- containment — the execute:wave:post hook must not render unless
  workflow.live_dom_uat is true AND the capability resolves active
  (fail-closed on a missing state entry, and on a non-boolean value)
- criterion 4 — agents/gsd-executor.md carries no browser MCP family;
  asserted as an absence, which is the only way it is observable
- Hyrum guard — the pre-existing mcp__playwright__* branch must stay
  outside the key-gated block, or upgrading silently removes working
  automated UI verification for every current Playwright-MCP user
- parity — the browser glob list now lives in two surfaces (agent
  frontmatter + workflow detection block); the assertion fails if
  either gains or loses a family without the other

Red by construction: the capability, agent and workflow block do not
exist yet. Verified on the remote runner.

* enhance(#2856): add default-off live-DOM UAT capability

A phase whose acceptance criteria needed a live DOM could not be
finished by the agent that executed it: gsd-executor carries no browser
tools, so it correctly returned checkpoint:human-action even though the
work was not human-only, just tool-less. Every such phase degraded to
"executed, then finished by hand in the orchestrator", and autonomous:
false could not distinguish "a human must judge this" from "the executor
lacks the tool".

Implements the shape approved at triage, not the one reported. The
executor's tools: line is NOT widened, in any configuration: for a
first-party agent the static list is the only control that exists
(ADR-1244 D2, ADR-857 D4, no per-dispatch override). Instead one
default-off capability owns the key, the agent, and the step:

- capabilities/live-dom-uat/ — activationKey workflow.live_dom_uat
  (boolean, default false), one additive step at execute:wave:post
  (onError: skip, gates: []), so it can never halt a wave
- agents/gsd-dom-verifier.md — the only GSD agent carrying browser MCP
  globs, in its own tools: line, with no Bash
- verify-work automated_ui_verification — a gsd:live-dom-families block
  naming both new families AND the key; presence alone never activates

Two independent fail-closed gates: isCapabilityActive renders a hook
only on state.active === true, plus the step's own `when`.

The pre-existing mcp__playwright__* branch keeps the gating it already
had and stays outside the new block. Pulling it behind a default-off key
would have silently removed working automated UI verification from every
current Playwright-MCP user on upgrade.

Also closes a host gap this surfaced: execute:wave:post dispatched only
contribution + gate, so ANY registered step was declared and silently
never run — exactly the single-kind hand-roll loop-hook-dispatch.md
names. Step 5.75 now dispatches every kind == "step".

The browser-profile lock is tolerated, not coordinated: --isolated is a
flag on the operator's own MCP-server registration that GSD neither
launches nor parameterizes, so the verifier reports could_not_look /
profile_locked, names the flag, and stops. DOM-VERIFY.md keeps
could_not_look and nothing_to_report distinct behind a closed reason
enum — collapsing them is the ambiguous-run-notes defect reported.

Verified on the remote runner.

Closes #2856

* fix(#2856): apply review findings from the orthogonal passes

Correctness pass (blocker):
- delete detectionBlockIsCrlfSafe. It was pass-always: it read the file,
  replaced LF with CRLF, then indexOf'd marker strings that contain no
  newline, so the replacement could not change the result and the
  assertion could never fail for the reason it stated. There is no real
  CRLF risk on this surface either — the gsd:live-dom-families block has
  no parser, only human and agent readers. Deleted rather than replaced,
  per the repo's pass-always-test rule.

Isolated security pass (two minors, both real):
- execute-phase.md step 5.75: this change is what first activates
  kind == "step" dispatch at execute:wave:post, which newly opens the
  ref.command shell path at that loop point. Our own step uses ref.agent
  and never touches it, but the door is now open, so the step-dispatch
  line carries the same in-context validate-before-shell warning the
  sibling gate-dispatch line directly below it already carries.
- gsd-dom-verifier: quoted page text in DOM-VERIFY.md is attacker
  influenced. Require it wrapped in inline code or a fence, kept short,
  and never left reading as a directive to the next reader.

Verified on the remote runner.

* fix(#2856): settle the new-agent roster ripple

Checkpoint 2 returned 28 failures, none in the new suite — all of them
the guards that exist to make adding an agent a deliberate act. Each is
a real boundary that had to move:

- docs/AGENTS.md: Tools row must copy the frontmatter verbatim (#2526),
  so the browser globs lose their backticks; primary-agent counts 21->22,
  roster 33/34->34/35, Verifiers category 1->2
- docs/INVENTORY.md: roster completeness requires every agents/gsd-*.md
  to be classified exactly once
- gsd-dom-verifier: add the anti-heredoc instruction and the commented
  hooks: frontmatter pattern both agent gates require
- gsd-core/bin/shared/model-catalog.json: every shipped agent needs a
  profile entry (#3229)
- copilot-install / kilo-upgrades / qwen-upgrades: expected agent list
  and the 34->35 roster boundary
- execute-wave-post-gate-pipeline-e2e: execute:wave:post legitimately
  carries one step now. Asserted as an exact shape — one step, capId
  live-dom-uat, ref.agent gsd-dom-verifier, onError skip — so it stays a
  real guard against accidental change rather than being relaxed

Two findings worth naming:

mcp-tool-inheritance (#2526) rejected the agent for documenting
mcp__playwright__* while its tools: line withholds it — a dead
instruction that invites the agent to claim a path it cannot take. The
prose now names the Playwright MCP family without the dispatchable
token, in both the agent and the capability fragment.

runtime-launcher-parity rejected the new gsd_run call: each fenced block
is its own shell, so a workflow step file invoking gsd_run needs its own
canonical preamble. Propagated with scripts/sync-runtime-launcher.cjs.
That script also normalizes explore.md, which is unrelated pre-existing
drift the parity check tolerates, so it is reverted to keep this diff
scoped.

The emitted-drift ack supersedes the spent #3370 entry for
execute-phase.md — it is merged into next, so its ripple is absorbed at
the base and it can no longer clear anything. That is the same supersede
the #3370 entry itself performed on the spent #3324 fragment. Its
unrelated execute-plan.md entry is untouched.

Verified on the remote runner.

* fix(#2856): drop the stale emitted-drift ack entry

The automated-ui-verification.md entry was written speculatively rather
than from a reported growth, and the check names that precisely: an ack
"written or reworded in THIS diff, but nothing here needed it, so it
explains nothing".

The growth tier keys on the bare filename as it appears under
gsd-core/workflows/ or agents/. automated-ui-verification.md is nested
under verify-work/steps/, so it was never in the tracked set — only
execute-phase.md was ever reported, both before and after the launcher
preamble landed.

Only ack what the check actually reports.

Verified on the remote runner.

* chore(#2856): backfill changeset pr number

pr:0 -> 3716. The placeholder fails both changeset-lint
(fail_invalid_fragment) and docs-lint (fail_malformed_fragment) by
design and can only be resolved once the PR number exists. Both now
report ok against GITHUB_BASE_REF=next.

Agent Contracts

Completion markers and handoff schemas for all GSD agents. Workflows use these markers to detect agent completion and route accordingly.

This doc describes what IS, not what should be. Casing inconsistencies are documented as they appear in agent source files.

Marker Rules

  1. ALL-CAPS markers (e.g., ## PLANNING COMPLETE) are the standard convention
  2. Title-case markers in gsd-verifier and gsd-integration-checker are intentional as-is, not bugs — a recorded decision. Their rows are artifact+query/structured-return (completion is detected through the row's Kind route), and the markers are carried as (unconsumed: Marker Rule 2 recorded decision …) annotations: an auditable exemption, never deleted and never silently passed. ## Synthesis Complete in gsd-doc-synthesizer was NOT covered by this rule; #3565 deleted it deliberately because it case-collides with gsd-research-synthesizer's ## SYNTHESIS COMPLETE and nothing matched it
  3. Non-standard markers (e.g., ## PARTIAL, ## ESCALATE) in audit agents indicate partial results requiring orchestrator judgment
  4. Kind describes how a caller actually detects an agent's completion, and is exactly one of:
    • sentinel-match -- a workflow, command, or another agent detects completion by an exact-case string match against a declared marker
    • artifact+query -- the agent writes a file (report, JSON, generated doc) and the caller reads or queries that artifact instead of matching any marker text
    • structured-return -- the agent has no way to write files (no Write tool) or simply doesn't; it returns parseable sections, a table, or JSON inline, and the caller reads that return text directly
  5. Markers must appear as H2 headings (## ) at the start of a line in the agent's final output
  6. The Consumed by / Kind columns are machine-enforced by check:contract-drift (scripts/check-contract-drift.cjs), which cross-checks this table against what each agents/*.md file actually emits in-fence and what every gsd-core/workflows/**, commands/**, and agents/** file actually consumes. Update this table whenever an agent's return contract changes -- a stale row is a violation the check will report, not something to leave for later.
  7. A marker entry annotated (unconsumed: <reason>) is emitted deliberately but matched by no workflow, command, or agent — e.g. ## ROADMAP DRAFT, a presentation format a human approves interactively. The check still verifies the marker is declared and emitted, and still counts it for case-collision purposes; only the consumer requirement is waived. Use it for display formats, never to silence a real orphan.

Key Handoff Contracts

Planner -> Executor (via PLAN.md)

Field Required Description
Frontmatter Yes phase, plan, type, wave, depends_on, files_modified, autonomous, requirements
<objective> Yes What the plan achieves
<tasks> Yes Ordered task list with type, files, action, verify, acceptance_criteria
<verification> Yes Overall verification steps
<success_criteria> Yes Measurable completion criteria

Executor -> Verifier (via SUMMARY.md)

Field Required Description
Frontmatter Yes phase, plan, subsystem, tags, key-files, metrics
Commits table Yes Per-task commit hashes and descriptions
Deviations section Yes Auto-fixed issues or "None"
Self-Check Yes PASSED or FAILED with details

Workflow Regex Patterns

Workflows match these markers to detect agent completion:

plan-phase.md matches:

  • ## RESEARCH COMPLETE / ## RESEARCH BLOCKED (researcher output)
  • ## PLANNING COMPLETE (planner output)
  • ## CHECKPOINT REACHED (planner/executor pause)
  • ## VERIFICATION PASSED / ## ISSUES FOUND (plan-checker output)

execute-phase.md matches:

  • ## PHASE COMPLETE (all plans in phase done)
  • ## Self-Check: FAILED (summary self-check)

NOTE: ## PLAN COMPLETE is the gsd-executor's completion marker but execute-phase.md does not regex-match it. Instead, it detects executor completion via spot-checks (SUMMARY.md existence, git commit state). This is intentional behavior, not a mismatch.
