Add credential routing instructions and WP-0003 workplan

Inline ops-warden credential routing guidance in AGENTS.md and mirror it
for Claude Code under .claude/rules/. Add IDENTITY-WP-0003 to backfill the
research corpus and refine the conceptual model against scenario tests.

+# Research corpus backfill and model refinement
+
+This workplan follows up on `ResearchProposal.md` Immediate Next Steps 4 and
+10. The seeded source notes under `research/` still contain `TODO` placeholders;
+the terminology, canon, model, and scenario artifacts from
+`IDENTITY-WP-0002` are candidate hypotheses until the corpus is backfilled.
+
+Priority order follows `OpenQuestions.md` corpus guidance: start with record and
+subject semantics (provisioning and federation), then authorization
+projections, then social graph, verifiable claims, and entity-resolution
+sources.
+
+## Backfill Provisioning And Federation Source Notes
+
+```task
+id: IDENTITY-WP-0003-T01
+status: todo
+priority: high
+```
+
+Backfill the nine source notes in `research/identity-provisioning/` and
+`research/authentication-federation/`. Replace template placeholders with
+source-backed terminology extracts, modeling assumptions, conflicts, candidate
+canonical mappings, and open questions. Use the structure defined in
+`research/CorpusIndex.md`.
+
+## Backfill Authorization And Social Graph Source Notes
+
+```task
+id: IDENTITY-WP-0003-T02
+status: todo
+priority: high
+```
+
+Backfill the eight source notes in `research/authorization-relationships/` and
+`research/social-community-graphs/`. Capture how each source models principals,
+subjects, actors, groups, organizations, tenants, and relationships without
+collapsing them into a single overloaded term.
+
+## Backfill Verifiable Claims And Entity-Resolution Source Notes
+
+```task
+id: IDENTITY-WP-0003-T03
+status: todo
+priority: medium
+```
+
+Backfill the six source notes in `research/verifiable-claims/` and
+`research/entity-resolution-privacy/`. Document synonymity, identifier,
+pseudonymity, and privacy semantics that affect canonical account-linking and
+relationship modeling.
+
+## Refresh Terminology Artifacts From Corpus
+
+```task
+id: IDENTITY-WP-0003-T04
+status: todo
+priority: high
+```
+
+Update `terminology/TerminologyInventory.md` and
+`terminology/TerminologyConflictMap.md` using extracted terminology from the
+backfilled source notes. Keep mappings marked as candidate until conflicts are
+reviewed against `canon/CanonicalGlossary.md`.
+
+## Refine Conceptual Model Against Scenario Tests
+
+```task
+id: IDENTITY-WP-0003-T05
+status: todo
+priority: high
+```
+
+Revise `model/ConceptualModel.md` so each scenario in
+`scenarios/ScenarioTests.md` has an explicit representation path. Record any
+scenario that the current model cannot satisfy without glossary or principle
+changes.
+
+## Reconcile Canon Surfaces And Open Questions
+
+```task
+id: IDENTITY-WP-0003-T06
+status: todo
+priority: medium
+```
+
+Update `canon/DesignPrinciples.md`, `canon/CanonicalGlossary.md`,
+`OpenQuestions.md`, and `DownstreamRecommendations.md` to reflect corpus
+findings. Resolve questions where the source evidence is sufficient; otherwise
+leave them open with citations to the relevant source notes.
