+# `@suaveplan/api-auth-anonymous` — Null-principal session resolver
+
+**Package**: `@suaveplan/api-auth-anonymous`
+**Status**: PROPOSED
+**Type**: new-package
+**Stage**: 4 (Base adapters) — see umbrella `openspec/changes/api-plugin-foundation/`
+
+## Why
+
+Per design doc §2.3, every API host MUST configure a session resolver — even fully public APIs. `api-auth-anonymous` is the trivial session resolver that always returns `null`. Configuring it explicitly makes the "no auth" choice visible in `host.json` and lets the rest of the host (RBAC gate, error envelope, OpenAPI) operate uniformly: the principal is simply `null`, never undefined.
+
+Stage 4 invariant: both direct and worker-proxy surfaces ship and pass `runAuthSessionConformance` (§5.2a, §13.4). The proxy is trivial here (no network/state) but its presence keeps the adapter table uniform — every adapter has both surfaces, no exceptions.
+
+## What changes
+
+Net-new package depending on `@suaveplan/api-auth`, `@suaveplan/api-types`, `@suaveplan/api-worker-rpc`.
+
+- ADDED: `createAnonymousSessionResolver()` — direct-surface factory returning an `AuthAdapter` whose `resolveSession` always returns `null`.
+- ADDED: `createAnonymousSessionResolverWorkerProxy(port)` — proxy-surface factory.
+- ADDED: `securitySchemeContribution()` — returns an empty OpenAPI `securitySchemes` block. Routes without `publicRoutes` declaration still emit the host's default security entry list (which is empty for anonymous).
+- ADDED: `AnonymousResolverOptions` — currently empty; reserved for future flags (e.g. `logAnonymousAccess: boolean`).
+
+## Out of scope
+
+- Policy on whether a route requires auth — the host enforces `publicRoutes` from each plugin's manifest; this resolver only ever supplies `null`.
+- Rate limiting based on IP / fingerprint — `api-rate-limit` Stage 8.
+
+## Source mapping
+
+Genesis-original. Source of design intent: `docs/superpowers/specs/2026-05-13-api-plugin-foundation-design.md`.
+
+| Requirement | Design doc section |
+|---|---|
+| Always returns null principal | §2.3 (`api-auth-anonymous` bullet) |
+| Worker-proxy variant required | §5.2a |
+| Conformance both surfaces | §13.4 |
+
+## Verification approach
+
+- `src/factory/create-anonymous-session-resolver.test.ts` — direct surface always returns null.
+- `src/factory/create-anonymous-session-resolver.spec-conformance.test.ts` — `runAuthSessionConformance("anonymous-direct", ...)` (the suite must accept resolvers that always return null).
+- `src/proxy/create-anonymous-session-resolver-worker-proxy.test.ts` — proxy unit tests.
+- `src/proxy/create-anonymous-session-resolver-worker-proxy.spec-conformance.test.ts` — `runAuthSessionConformance("anonymous-worker-proxy", ...)`.
+
+## Migration impact
+
+None — additive only.

+# Capability Spec Delta: api-auth-anonymous (api-auth-anonymous)
+
+**Package**: `@suaveplan/api-auth-anonymous`
+**Status**: PROPOSED
+
+## ADDED Requirements
+
+### Requirement: resolveSession always returns null
+
+The package SHALL implement the session-resolver contract such that `resolveSession(request)` returns `null` for every input, synchronously decidable.
+
+#### Scenario: any request resolves to null
+
+- **WHEN** `resolveSession(request)` is called with any request shape (Authorization header, cookie, missing entirely)
+- **THEN** the resolver returns `null` AND no exception is thrown AND no network I/O occurs
+
+**Verified by:** `src/factory/create-anonymous-session-resolver.test.ts::"resolveSession returns null for every input"`
+
+---
+
+### Requirement: Direct and worker-proxy surfaces both pass conformance
+
+The adapter SHALL pass `runAuthSessionConformance` under BOTH the direct and worker-proxy surfaces. The conformance suite MUST tolerate a resolver that exclusively returns null (the "no auth configured" case is a valid host topology).
+
+#### Scenario: direct surface conforms
+
+- **WHEN** `runAuthSessionConformance("anonymous-direct", createAnonymousSessionResolver)` runs
+- **THEN** every invariant passes
+
+#### Scenario: worker-proxy surface conforms
+
+- **WHEN** `runAuthSessionConformance("anonymous-worker-proxy", () => createAnonymousSessionResolverWorkerProxy(channel.port2))` runs over a real `MessageChannel`
+- **THEN** every invariant passes
+
+**Verified by:** `src/factory/create-anonymous-session-resolver.spec-conformance.test.ts::"anonymous-direct conforms to AuthSession contract"` AND `src/proxy/create-anonymous-session-resolver-worker-proxy.spec-conformance.test.ts::"anonymous-worker-proxy conforms to AuthSession contract"`
+
+---
+
+### Requirement: Empty securitySchemes contribution
+
+`securitySchemeContribution()` SHALL return an empty `securitySchemes` block. OpenAPI documents assembled from a host using only this resolver MUST emit no `security` entry on routes.
+
+#### Scenario: contribution is empty
+
+- **WHEN** `securitySchemeContribution()` is called
+- **THEN** the returned value is `{ securitySchemes: {} }`
+
+**Verified by:** `src/security-scheme/security-scheme-contribution.test.ts::"contribution exposes no security schemes"`

+# Tasks — `@suaveplan/api-auth-anonymous`
+
+> Every checkbox MUST reflect work actually done in this change.
+
+## 0. Pre-flight (non-negotiable)
+
+- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
+- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
+- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.
+
+## 1. Spec authoring
+
+- [x] 1.1 Read design doc (§2.3, §5.2a, §13.4)
