+## Research Activation
 
-This agent delegates evolving accessibility standard lookups, regulatory update checks, and assistive-technology compatibility research to `Researcher Subagent`.

+Provide the skill with:
 
-* Research topic(s) and question(s) to investigate.
-* Subagent research document file path to create or update under `.copilot-tracking/research/subagents/{YYYY-MM-DD}/`.
+* The topic and purpose tied to the active phase and enabled framework.
+* The audience and intended use, including the phase outputs and qualified reviewers that will consume the evidence.
+* Explicit research questions and evidence criteria.
+* Scope and non-goals, including permitted sources, versions, surfaces, and assistive technologies.
+* Constraints such as licensing, quotation limits, regulatory currency, and user-confirmation dependencies.
+* Supplied evidence from `state.json`, active phase artifacts, loaded framework guidance, and user-provided references.
+* Requested outputs and output mode, using `analysis` unless the user requests another supported mode.
+* `.copilot-tracking/accessibility/{project-slug}/` as a trusted alternate evidence root.

+Require `rpi-research` to mirror `research/YYYY-MM-DD/<task-slug>-research.md` and `research/subagents/...` beneath the trusted root. The skill resolves the exact date, task slug, artifact paths, worker selection, lane contracts, budgets, and research synthesis.
 
-* When `runSubagent` or `task` is available, run subagents as described and per any phase-specific delegation triggers in the instruction files.
-* When neither tool is available, inform the user that one of these tools must be enabled. Do not fabricate or synthesize regulatory or standards content from training data.
-
-Subagents can run in parallel when researching independent framework domains (for example, EN 301 549 versioning concurrent with Section 508 procurement-rule updates).
+After completion, read the returned primary research artifact and synthesize applicable findings into the active phase artifacts and `state.json`, preserving normative-source provenance and every existing confirmation gate. Treat `Blocked` and `Needs clarification` as unresolved evidence: record the smallest gap and stop dependent mapping work. If `rpi-research` or a required lookup capability is unavailable, report the limitation rather than substituting training-data claims.

+* **Research boundary**: Stay structured and evidence-based. Do not turn this into a generic summary or duplicate the `rpi-research` workflow.
 
 ## Required Steps
 
-1. **Read input.** Read `diff-state.json` once for `branch`, `base`, `files`, `findingsFolder`, `boardItem`, `question`, and `researchDocumentPath`. In the same parallel block, read the Skill Reference Contract files and the generic researcher subagent contract.
-2. **Dispatch to research.** Invoke the generic Researcher Subagent with the board item question and a research document path inside the review folder. Use `researchDocumentPath` when provided; otherwise default to `<findingsFolder>/walkback/<boardItemId>-research.md` so the researcher writes into the review folder rather than the default `.copilot-tracking/research/subagents/` location. Do not re-implement the research protocol; delegate it.
-3. **Anchor the result.** Read the researcher output once it is written, then create or update a Register 2 artifact in the review folder for that board item. Include the board item id, the research question, the evidence summary, references, and any follow-on questions. Preserve the links and selectable symbols for later board merge.
-4. **Return a concise summary.** Return the artifact path and a short status note. If the research is blocked, capture the blocker plainly and stop rather than filling the artifact with speculation.
+1. **Read input.** Read `diff-state.json` once for `branch`, `base`, `files`, `findingsFolder`, `boardItem`, `question`, `investigationId`, `researchTopic`, `researchPurpose`, `researchAudienceUse`, `researchQuestions`, `evidenceCriteria`, `researchScope`, `researchNonGoals`, `researchConstraints`, `suppliedEvidence`, `researchRequestedOutputs`, `researchOutputMode`, `trustedEvidenceRoot`, and `register2ArtifactPath`. In the same parallel block, read the Skill Reference Contract files.
+2. **Validate the activation inputs.** Require every scoped input to be explicit. Confirm that `trustedEvidenceRoot` equals `findingsFolder`, is explicitly trusted by the parent, and is distinct from `diff-state.json`. Confirm that `register2ArtifactPath` is beneath `<findingsFolder>/walkback/` and contains no unresolved placeholder. Return `Needs clarification` without writing when an input or path is missing or invalid.
+3. **Activate research.** Activate `rpi-research` with the topic, purpose, audience and intended use, questions, evidence criteria, scope and non-goals, constraints, supplied evidence, requested outputs, output mode, and trusted alternate evidence root. Require the skill to mirror `research/YYYY-MM-DD/<task-slug>-research.md` and `research/subagents/...` beneath that root. Let the skill resolve the exact date, task slug, primary and delegated artifact paths, worker selection, lane contracts, budgets, and research synthesis.
+4. **Anchor the result.** When research completes, read the returned primary research artifact once, then create or update the Register 2 artifact at `register2ArtifactPath`. Include the board item id, research question, evidence summary, references, unresolved evidence, and follow-on questions. Preserve links and selectable symbols for later board merge. Treat `Blocked` or `Needs clarification` as unresolved evidence: record only the status and smallest blocker when the Register 2 path is valid, then stop.
+5. **Return a concise summary.** Return the Register 2 artifact path, primary research artifact path, execution status, and a short board-item status note. Do not repeat the primary artifact in the response.
+
+## Stop Rules
+
+* If `rpi-research` or a required lookup capability is unavailable, return `Blocked` and name the unavailable capability. Do not synthesize uncertain code, standards, or external evidence from training data.
+* Stop when the skill reports that its evidence criteria are met or identifies the smallest unresolved evidence gap.
