feat(stage7): broker-server vertical slice + three-role docs#60
Merged
Conversation
Resolves #58 phase 1 — the credential broker that lets app developers run daemons against operator infrastructure without holding any AWS keys. Doc reframe (front-loaded per CEO-review Q3): - docs/dev-setup.md rewritten around three roles (app developer / operator / end user). Each role's setup is its own section. - docs/operator-runbook.md (new) — start, supervise, rotate, audit. Calls out v0.1 scope vs Stage 7 phase 2 (OIDC) vs Stage 8 (vault). New crate crates/agentkeys-broker-server/ (vertical slice per CEO-review Q1): - POST /v1/mint-aws-creds — bearer auth via backend's new /session/validate, sts:AssumeRole on operator's daemon key, returns 1h temp creds. Static-IAM path; assume-role-with-web-identity deferred to phase 2. - GET /healthz, /readyz — supervisor probes; readyz exercises backend reachability + sts:GetCallerIdentity. - SQLite audit log on every mint (sha256-hashed bearer tokens, wallet, outcome, sts session name) at $HOME/.agentkeys/broker/audit.sqlite. - Trait-abstracted StsClient with AwsStsClient + StubStsClient (test-stub feature) — testable without live AWS. Env-var config only. mock-server adds GET /session/validate so the broker validates tokens through the backend instead of duplicating session state. Broker stays stateless w.r.t. sessions; backend is single source of truth. agentkeys-daemon gains --broker-url / AGENTKEYS_BROKER_URL flag (consumer wiring lands in phase 2 alongside provisioner-script integration). Tests: 3 unit + 5 broker integration (mock-backend + stub STS) — full workspace cargo test passes 194/194, no regressions. Out of scope (explicit, deferred): - OIDC discovery / JWKS / AssumeRoleWithWebIdentity — phase 2 (gated on public-hosting prereq, docs/stage7-wip.md §1). - TS oidc-stub retirement — phase 2. - Provisioner-scripts AWS-cred consumer rewiring — phase 2.

Address /plan-eng-review findings on PR #60 phase 1. Critical (silent-failure trio): - audit.rs: replace lock().unwrap() with lock_conn() that propagates poison as BrokerError::AuditError instead of panicking the tokio worker. - mint.rs: failure-path audit writes were silently swallowed (let _ = ...); now route through record_outcome() which logs at error level on audit insert failure so anomaly-detection blindness is visible to operators. - main.rs: warn loudly when binding to a non-loopback address (bearer tokens + minted AWS creds in cleartext otherwise — terminate TLS at a reverse proxy first). Reliability: - main.rs: validate STS creds at startup (--skip-startup-check escape hatch for offline dev). Misconfigured creds now fail to bind, not on first mint. - main.rs: graceful shutdown on SIGTERM/Ctrl-C drains in-flight requests via with_graceful_shutdown(); prevents orphan audit rows where the daemon never received the response. - mint.rs: build_session_name now appends a microsecond suffix; same wallet minting twice within a second no longer collides on STS session name. Observability: - mint.rs: #[tracing::instrument] span on mint_aws_creds, with wallet + outcome fields recorded as the request progresses. DRY + tests: - mint.rs: pull record_outcome() helper; three near-identical audit-insert call sites collapse to one. - StubStsClient: closure-backed; new ::ok / ::failing / ::assume_failing factory methods cover happy/down/partial-down test scenarios. - audit.rs: new AuditLog::last_row() + hash_token exported for test introspection. - 9 broker integration tests (was 5) — added STS-error path, backend-down path, both readyz failure modes, and audit-row assertions on every mint. - 4 new audit unit tests covering hash_token determinism, distinct hashes, record-mint roundtrip, failure-detail persistence. Test count workspace-wide: 203 / 203 passing (was 194). No regressions. Refs #58, addresses /plan-eng-review findings #1, #2, #3, #4, #6, #10, #12, #13.

Address 7 issues from the codex review on top of /plan-eng-review. Critical: - audit.rs: column name `requester_token` stored hashed values, misleading any operator querying it. Renamed to `requester_token_hash` to match what's actually written. The Rust struct already used the correct name; only the SQLite schema and the SELECT lagged. - audit.rs: enable WAL + synchronous=FULL on the audit DB. Default journal mode could lose recent rows on power loss; for an audit log durability beats throughput. Reliability: - audit.rs: new MintOutcome::BackendError variant. Backend-unreachable was previously written as "auth_failed", which made operator anomaly detection blind to backend outages (looked like a token-fishing spike). - config.rs: BROKER_SESSION_DURATION_SECONDS parse failure now surfaces as a startup error instead of silently falling back to 3600. - config.rs: new BROKER_BACKEND_TIMEOUT_SECONDS (default 10s) and BROKER_SHUTDOWN_GRACE_SECONDS (default 30s). - main.rs: reqwest client gets the configured timeout + a 5s connect timeout. Previously a hung backend would pin a tokio task forever. - main.rs: graceful-shutdown future races a hard-cap sleep so a single hung request can't block process exit indefinitely. - main.rs: SIGTERM handler now expect()s on registration. Failing loud is better than the prior `if let Ok(...)` which would silently exit on startup in hardened-sandbox environments. Audit perf nit: - audit.rs: compute timestamp + token hash before grabbing the mutex so the critical section is purely the SQLite write. Tests updated: - mint_flow.rs: backend-unreachable test now asserts outcome="backend_error" (was "auth_failed"). - mint_flow.rs: BrokerConfig now constructs with the two new timeout fields; test reqwest client gets short timeouts. Test count workspace-wide: 203 / 203 passing. No regressions. Refs #58, addresses codex review findings on PR #60. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
stage7-wip.md previously described Stage 7 as one undifferentiated "not running yet" surface. With PR #60 phase 1 (broker server) shipped, the doc was misleading: readers couldn't tell what's live, what isn't, or where the operator runbook had moved to. Restructured around the two halves: - Phase 1 (shipped) — points at crates/agentkeys-broker-server/, the three-role dev-setup.md, and the operator-runbook. Includes the three-terminal e2e proof (mock backend + broker + curl mint). - Phase 2 (deferred) — preserves the existing OIDC federation test recipe (IAM provider registration, federated trust policy, PrincipalTag bucket policy, JWT mint via TS stub, cross-prefix AccessDenied proof). Reframed as "still blocked on public hosting + TEE-derived ES256 key per heima-gaps §3." Refs #58. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The team persists BROKER_DAEMON_* in ~/.zshenv (mode 0600), not in a 1Password vault accessed via `op read`. Update the three Stage 7 docs to match actual operator workflow: - docs/operator-runbook.md §3.1 now describes ~/.zshenv (or supervisor env-injection) instead of recommending 1Password CLI. Adds the "shared/untrusted host" caveat for systemd LoadCredential / launchd EnvironmentVariables fallback. - docs/operator-runbook.md §5 (rotation): updates step 2 from "update your secret store (1Password)" to "update ~/.zshenv". - docs/operator-runbook.md §9 (out-of-scope): retitles "1Password CLI integration" to "secret-manager integration" generally. - docs/dev-setup.md §1 (optional tools): removes 1Password CLI bullet. - docs/dev-setup.md §3 (role table): "1Password" → "~/.zshenv or supervisor-managed env" in the operator row. - docs/dev-setup.md §5.1: replaces "stash in 1Password" with the ~/.zshenv persistence pattern. - docs/dev-setup.md §5.2 + §5.4: removes inline `op read` calls from the broker-startup snippets; comments now state BROKER_DAEMON_* are inherited from the shell. - docs/stage7-wip.md phase-1 e2e proof: same op-read removal. No code changes. The broker still reads BROKER_DAEMON_* from std::env exactly as before; only the operator-facing instructions changed. Refs #58. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Operator's ~/.zshenv already defines: DAEMON_ACCESS_KEY_ID DAEMON_SECRET_ACCESS_KEY ACCOUNT_ID REGION BUCKET DOMAIN scripts/stage6-demo-env.sh has read DAEMON_ACCESS_KEY_ID + DAEMON_SECRET_ACCESS_KEY since Stage 6. Introducing a second naming scheme (BROKER_DAEMON_*) for the same long-lived keys forces operators to either duplicate exports or rewrite ~/.zshenv. Align instead. Code (config.rs): - BROKER_DAEMON_ACCESS_KEY_ID env var renamed to DAEMON_ACCESS_KEY_ID, with BROKER_DAEMON_ACCESS_KEY_ID kept as a fallback for explicit callers. Same for DAEMON_SECRET_ACCESS_KEY. - BROKER_AGENT_ROLE_ARN now optional: if unset, derived from ACCOUNT_ID as arn:aws:iam::$ACCOUNT_ID:role/agentkeys-agent (the Stage 6 canonical role name). Operator can still override. - BROKER_AWS_REGION now falls back to REGION (the rest-of-agentKeys convention) before defaulting to us-east-1. - New first_env() helper picks the first non-empty match from a list of candidate env-var names. Docs: - docs/operator-runbook.md §3.1: env-var schema table updated; ~/.zshenv example shows REGION + ACCOUNT_ID + DAEMON_* (matches actual zshenv layout). Two new vars from prior commit (BROKER_BACKEND_TIMEOUT_SECONDS, BROKER_SHUTDOWN_GRACE_SECONDS) added to the table. - docs/operator-runbook.md §5: rotation step references DAEMON_*. - docs/dev-setup.md §5.2 + §5.4: the explicit `export BROKER_AGENT_ROLE_ARN=...` line drops out — broker derives from ACCOUNT_ID. Now the only per-run var is BROKER_BACKEND_URL. - docs/stage7-wip.md phase-1 e2e: same simplification. Tests: 17 / 17 broker tests passing (BrokerConfig is constructed literally in tests, so the env-var rename doesn't affect them). Refs #58.

…sue #64, #71 Option A) (#73) * agentkeys: stage 7 issue#64 phase 0 -- US-001 src/env.rs centralized env-var module Implement plan §5: single source of truth for every BROKER_* environment variable name. Per user rule 11, no other module may declare a raw env-var literal — all reads go through these constants. - crates/agentkeys-broker-server/src/env.rs (new): const &str declarations for all 51 env vars (Phase 0 + planned A/B/C/D/E + legacy aliases), Group enum (Core/Oidc/SessionJwt/Audit/AuditEvm/Auth/AuthEmail/AuthOAuth2/ Limits/Legacy), all() registry returning (name, doc, group), print_table() for the operator runbook auto-generator. 5 unit tests cover uniqueness, non-empty docs, required-Phase-0 presence, table render row count, and Group exhaustiveness. - crates/agentkeys-broker-server/src/lib.rs: register pub mod env. - crates/agentkeys-broker-server/src/config.rs: replace every raw BROKER_* string literal with env::* constants. grep -E '"(BROKER_|DAEMON_|ACCOUNT_ID|REGION)' src/config.rs returns zero hits. Adds parse_int_env_with_default<T> helper to collapse three near-duplicate parse blocks. Plan home: docs/spec/plans/issue-64/{PLAN.md (mirror), DECISIONS.md, AMBIGUITIES.md, V0.1-FOLLOWUPS.md, prd.json (PRD-driven ralph)}.

No plug-in implementations yet (US-006 implements WalletSig, US-007 ClientSideKeystore, US-008 SqliteAnchor) — this story lands the trait shapes, error types, and registry that the later stories slot into. - crates/agentkeys-broker-server/src/plugins/mod.rs (new): Readiness enum (Ready/Degraded/Unready), PluginRegistry { auth: HashMap, wallet, audit: Vec }, aggregate_readiness() → (overall, per-check) for the /readyz JSON. Trait re-exports. - crates/agentkeys-broker-server/src/plugins/auth.rs (new): UserAuthMethod trait (name/ready/challenge/verify), VerifiedIdentity, ChallengeParams, AuthChallenge, AuthResponse, IdentityType { Evm, Email, OAuth2{Google, Github,Apple} } with stable canonical() strings (input to OmniAccount derivation; renaming is breaking). AuthError enum. - crates/agentkeys-broker-server/src/plugins/wallet.rs (new): WalletProvisioner trait (name/ready/bind_address/lookup_by_omni_account), WalletAddress newtype with parse() that normalizes 0x-prefixed hex to lowercase + length check, WalletRole { Master, Daemon }, WalletBinding struct. WalletError enum. - crates/agentkeys-broker-server/src/plugins/audit.rs (new): AuditAnchor trait (name/ready/anchor/verify), AuditRecord with record_hash for cross-anchor dedup, AnchorReceipt, AuditPolicy { DualStrict, SqlitePrimary, EvmPrimary } parser.

Optional features for v0-testnet (auth-email-link, auth-oauth2-google, audit-evm) and v1+ (auth-oauth2-github, auth-oauth2-apple, audit-solana). External deps land in implementation stories (US-006: k256+sha3; Phase A.1: lettre+aws-sdk-sesv2; Phase C: alloy-*).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * agentkeys: stage 7 issue#64 phase 0 -- US-004 OmniAccount + US-008 SqliteAnchor port Bundles two stories that became coupled when the agentkeys-types::AgentIdentity extension forced match-arm updates across four crates and the audit/ module restructure required relocating both the trait file and the SqliteAnchor implementation in the same change. US-004 — OmniAccount derivation - crates/agentkeys-broker-server/src/identity/{mod.rs,omni_account.rs} (new): derive_omni_account(identity_type, identity_value) → SHA256(client_id || type || value) with hardcoded AGENTKEYS_CLIENT_ID = "agentkeys". Per port- vs-greenfield "What we port — crypto primitives only", this matches the dexs-backend hash shape verbatim but uses our own client_id, giving each operator a sovereign identity namespace. derive_with_client_id(...) is exposed for reproducing dexs reference vectors in tests. - crates/agentkeys-types/src/lib.rs: AgentIdentity::OAuth2{provider, sub} variant added (additive — every existing AgentIdentity consumer continues to work unchanged for the four prior variants). - Match-arm updates across consumers (Rust E0004 non-exhaustive errors surfaced these — exactly the property we want from the type system): - crates/agentkeys-core/src/mock_client.rs (open_auth_request + session_recover): map OAuth2{provider,sub} → ("oauth2_<provider>", sub) matching the broker's IdentityType::canonical() naming. - crates/agentkeys-core/src/auth_request.rs: deterministic CBOR encoding of OAuth2 — Map[("provider", Text), ("sub", Text)] with keys ASCII- sorted so the canonical hash is stable. - crates/agentkeys-cli/src/lib.rs: rich-error human-readable form "oauth2_<provider>:<sub>". - crates/agentkeys-mock-server/src/test_client.rs: same mapping as mock_client (auth-request and session-recover paths). - 9 identity:: unit tests cover: hex parse validation, derivation determinism, identity-type namespace separation, identity-value separation, client_id namespace separation (load-bearing — proves agentkeys ≠ wildmeta for the same email), prod entry-point matches hardcoded constant, lowercase-hex output guarantee. US-008 — SqliteAnchor port to AuditAnchor trait - crates/agentkeys-broker-server/src/plugins/audit/{mod.rs,sqlite.rs} restructured: trait file `audit.rs` merged into `audit/mod.rs` so the feature-gated `audit-sqlite` submodule can live alongside it. (Previous layout had `audit.rs` + `audit/mod.rs` which Rust E0761'd.) - src/plugins/audit/sqlite.rs (new): SqliteAnchor implementing AuditAnchor. Schema is the new plugin_mint_log table with the canonical AuditRecord columns + a status column (Phase 0 writes 'confirmed' directly; Phase C introduces the pending → confirmed | quarantined lifecycle). Indexes on minted_at, omni_account, record_hash, status. WAL+FULL pragma preserved from the legacy crate::audit::AuditLog. - Readiness::Ready when DB writable; Unready otherwise. - 8 plugins::audit:: tests cover: anchor round-trip, verify NotFound, record_hash tampering detection, wrong-anchor receipt rejection, ready reports Ready, name() stability + AuditPolicy parse + AuditRecord round trip. Acceptance criteria (US-004): - src/identity/omni_account.rs derive_omni_account(...) ✓ - AGENTKEYS_CLIENT_ID = "agentkeys" pinned ✓ - agentkeys-types::AgentIdentity::OAuth2{provider, sub} added ✓ - Tests cover canonical hash for each identity type ✓ - cargo test identity:: 9/9 pass ✓ Acceptance criteria (US-008): - src/plugins/audit/sqlite.rs implements AuditAnchor ✓ - plugin_mint_log table with canonical columns + indexes ✓ - WAL+FULL pragma preserved ✓ - verify() detects record_hash tampering ✓ - Readiness Ready when writable ✓ - cargo test plugins::audit:: 8/8 pass ✓ Note: legacy crate::audit::AuditLog (the existing src/audit.rs) is left in place for now — US-011 migrates the mint handler to the new trait and drops the legacy module then. Carrying both during the transition keeps existing /v1/mint-aws-creds working. Refs: issue #64 plan §3.5 (OmniAccount), §3 (AuditAnchor trait), §Phase 0 deliverables.

Closes Codex / eng-review #7 footgun: an operator pointing BROKER_SESSION_KEYPAIR_PATH at the OIDC keypair file would have silently used the wrong key (same kid, same crypto), letting session tokens pass as IAM federation tokens. Defense: on-disk JSON now carries a "purpose" field; load-time validation refuses to read a keypair whose purpose does not match the slot. - crates/agentkeys-broker-server/src/jwt/{mod,session,issue,verify}.rs (new): KeypairPurpose enum (Oidc | Session) with stable kebab-case canonical() and kid_prefix(); SessionKeypair (mirror of OidcKeypair, purpose-tagged on disk, kid prefix `ak-session-`); mint_session_jwt() with the canonical session-JWT claim shape (iss/sub/aud=agentkeys:broker/exp/iat/jti + agentkeys.{omni_account,wallet_address,identity_type,identity_value}); verify_session_jwt() that pins audience + issuer + kid header. - crates/agentkeys-broker-server/src/oidc.rs: - PersistedKeypair: add `purpose` field with #[serde(default)] mapping to KeypairPurpose::Oidc so pre-Stage-7 keypair files (no purpose field) continue to load as oidc. New keypairs always include the field. - load() refuses any keypair whose purpose ≠ Oidc. - generate_and_persist() writes purpose=oidc. - rand_core_compat → pub(crate) rand_compat (so SessionKeypair can reuse the rand_core 0.6 → OS RNG bridge). - set_owner_only → pub(crate) set_owner_only_inner (same reason). - crates/agentkeys-broker-server/src/lib.rs: register pub mod jwt. Acceptance criteria (US-005): - src/jwt/mod.rs: KeypairPurpose with Oidc + Session ✓ - On-disk JSON includes "purpose" field ✓ - SessionKeypair::load refuses purpose=oidc keypair ✓ - SessionKeypair::load refuses untagged JSON ✓ - OidcKeypair::load refuses purpose=session keypair ✓ - Session JWT mint+verify round trip ✓ - verify rejects wrong audience, wrong issuer, expired ✓ - session keypair kid prefix `ak-session-`; oidc kid format unchanged ✓ - cargo test jwt:: 10/10 pass ✓ - cargo build green ✓ env.rs already has BROKER_SESSION_KEYPAIR_PATH and BROKER_SESSION_JWT_TTL_SECONDS (landed in US-001).

The broker stores ONLY (omni_account, address, role, parent_address, created_at) — the user holds the seed in their OS keychain on the daemon side. The broker has no key material it could leak. Storage layer: - crates/agentkeys-broker-server/src/storage/{mod.rs, wallets.rs} (new): WalletStore with composite-PK schema (omni_account, address) so a user can have multiple wallets and re-binding the same address is idempotent. WAL+NORMAL for throughput (audit log gets FULL elsewhere). bind() detects role mismatch and parent mismatch on re-bind — a daemon switching masters or an address flipping role would be silent data corruption otherwise. list_for_omni_account() returns every wallet bound to the OmniAccount. writable() probe used by the plugin's ready(). Plugin layer: - crates/agentkeys-broker-server/src/plugins/wallet/{mod.rs,keystore.rs}: module restructure from sibling-file `wallet.rs` to `wallet/mod.rs + wallet/keystore.rs` (same E0761 fix as US-008's audit module). ClientSideKeystoreProvisioner implements WalletProvisioner. name() = "client_keystore". ready() reflects WalletStore::writable() (NOT a hardcoded Ready, per plan §1 rule 5). bind_address() stamps current unix-seconds and delegates to WalletStore::bind. lookup_by_omni_account delegates to WalletStore::list_for_omni_account. - crates/agentkeys-broker-server/src/lib.rs: register pub mod storage.

Closes Codex P0 #2 (raw EIP-191 was replayable across apps; SIWE binds domain). Storage: - crates/agentkeys-broker-server/src/storage/auth_nonces.rs (new): AuthNonceStore with single-use semantics. issue() inserts, consume() is race-safe via WHERE consumed_at IS NULL conditional UPDATE, purge_expired() janitors old rows. ConsumeOutcome enum collapses "never existed" and "already consumed" into NotFoundOrConsumed so an attacker cannot probe the nonce table; Expired is a separate variant so the broker can surface a "your sign-in expired" message. 7/7 tests pass. Plugin: - crates/agentkeys-broker-server/src/plugins/auth/{mod.rs ⟵ ex auth.rs, wallet_sig.rs} (restructure + new): Same E0761 module-conflict fix as US-007/008. SiweWalletAuth implements UserAuthMethod. challenge() builds an EIP-4361 SIWE message with the broker's domain, fresh CSPRNG nonce, issued_at, expiration_time (issued_at + 45min), URI, chain_id, resources. verify() looks up the pending challenge, atomically consumes the nonce, runs k256 ecrecover via the EIP-191 envelope (`\x19Ethereum Signed Message:\n<len><msg>` → keccak256 → recover_from_prehash), and asserts the recovered address matches the SIWE message's claimed address. ecrecover_address() handles v ∈ {0,1,27,28} (k256 RecoveryId requires {0,1}, so 27/28 are normalized). Per-call security: - SIWE domain field bound to broker's host (replay across apps blocked) - Nonce single-use enforced via AuthNonceStore (replay across requests blocked) - 45-min issued_at/expiration window (replay across long timeframes blocked) - k256 0.13 enforces canonical signatures (low-s) by default - Chain-ID bound into the SIWE message (replay across chains blocked) Pending challenges live in tokio::sync::Mutex<HashMap> keyed by request_id; removed on first verify() attempt to prevent in-memory replay even if the on-disk nonce check is flaky. Multi-process deployments would move this to SQLite — out of scope for v0. Custom ISO8601 formatter (no chrono dep). Howard-Hinnant civil_from_days valid 1970+. Tests pin format shape. Embeds the canonical IdentityType enum + UserAuthMethod trait + supporting types (VerifiedIdentity, ChallengeParams, AuthChallenge, AuthResponse, AuthError) in plugins/auth/mod.rs — preserved verbatim from the previous plugins/auth.rs file with feature-gated re-export of SiweWalletAuth.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * agentkeys: stage 7 issue#64 phase 0 -- US-003 tiered refuse-to-boot + plugin-registry wiring Implement plan §6 tiered refuse-to-boot. Closes Codex P1 #6 (transient external dependencies must not brick startup): Tier 1 (synchronous, before listener bind): - All required env vars present + parseable + types in declared bounds. - BROKER_OIDC_ISSUER must be https:// in non-dev mode (BROKER_DEV_MODE=true relaxes; logged loudly). - OIDC keypair file MUST exist + parse + carry purpose=oidc tag (refuses purpose=session). - Session keypair file MUST exist + parse + carry purpose=session tag (no migration window). - SQLite migrations run cleanly via AuthNonceStore::open + WalletStore::open + SqliteAnchor::open. Each CREATE TABLE IF NOT EXISTS is the v0 migration. - BROKER_AUTH_METHODS / BROKER_WALLET_PROVISIONER / BROKER_AUDIT_ANCHORS resolve at compile time (every name must map to an enabled feature; unknown names → boot fail with anchor `auth-method-not-compiled` etc.). - BROKER_AUDIT_POLICY parses to {dual_strict, sqlite_primary, evm_primary}. - Failure: exit code 1 with single-line `BOOT_FAIL: <var>=<value>: <reason>; see runbook §<anchor>`. Tier 2 (async, after listener bound): - Backend `/healthz` reachability probe loops every 15s until success; flips state.tier2.backend_reachable. - /healthz returns 200 immediately (liveness); /readyz aggregates Tier-2 atomic flags + plugin Readiness (US-012 lands the aggregator handler — for now /readyz still uses the legacy flat probe pre-broker_status migration). - BROKER_REFUSE_TO_BOOT_STRICT=true collapses Tier-2 backend probe to a hard fail (process exits if backend not reachable). - SES + EVM probes deferred to Phase A.1 + Phase C respectively, behind their feature gates. The Tier2State struct already carries the AtomicBool fields so adding probes is one-line each. Files: - crates/agentkeys-broker-server/src/boot.rs (new): run_tier1() returns BootArtifacts (registry + keypairs + stores + audit_policy). build_registry() constructs PluginRegistry from BROKER_AUTH_METHODS / BROKER_WALLET_PROVISIONER / BROKER_AUDIT_ANCHORS. Tier2Profile::from_config() probes which Tier-2 checks are enabled. 4 unit tests cover https-only refuse, missing keypair refuse, url_host extraction, Tier2Profile detection. - crates/agentkeys-broker-server/src/state.rs (extended): AppState now carries session_keypair, registry, audit_policy, wallet_store, nonce_store, tier2 (Arc<Tier2State> with 4 AtomicBool fields). Legacy `audit: AuditLog` preserved through US-011. - crates/agentkeys-broker-server/src/main.rs (rewritten): calls run_tier1() → BootArtifacts before STS check. spawn_tier2_probes() spawns the backend reachability probe with 15s retry; strict mode exits the process on first miss. - crates/agentkeys-broker-server/src/lib.rs: pub mod boot. - crates/agentkeys-broker-server/tests/{oidc_flow,mint_flow}.rs: stub the new AppState fields with in-memory stores + fresh session keypair so the legacy backend-bearer-mint integration tests continue to pass unchanged. Acceptance criteria (US-003): - src/boot.rs with run_tier1() (sync) + Tier2Profile::from_config() (Tier-2 spawn) ✓ - Tier-1 validates env vars present + paths readable + OIDC https in non-dev ✓ - Plugin registry validates: every name in BROKER_AUTH_METHODS / etc. resolves ✓ - Tier-1 runs SQLite migrations cleanly ✓ - Keypair load: refuse-to-boot if path absent or purpose tag mismatch ✓ - Tier-2 reachability checks marked async ✓ - BOOT_FAIL message format with runbook anchor ✓ - 4 boot:: tests pass ✓ - Full broker test suite 94 tests pass (79 lib + 9 mint_flow + 6 oidc_flow) ✓ - cargo build green ✓ Refs: issue #64 plan §6 (tiered refuse-to-boot), §3 (PluginRegistry), §Phase 0 deliverables. Closes codex review finding P1 #6 (refuse-to-boot vs Unready). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * agentkeys: stage 7 issue#64 phase 0 -- US-012 broker_status /readyz aggregator Per plan §7 + Designer review #status-shape: /readyz now aggregates PluginRegistry::aggregate_readiness() across every loaded plug-in PLUS the four Tier-2 reachability AtomicBool flags (set asynchronously by spawn_tier2_probes in main.rs). Behavior: - 200 with empty body when every plug-in Ready + every relevant Tier-2 flag set. Operators tailing curl see no noise on the happy path. - 200 with `{"status":"degraded","degraded":true,"checks":[...], "ready":[...]}` when any plug-in reports Degraded. Body lists every degraded check with `name`, `status`, `reason`, and a `docs` URL anchor pointing into the operator runbook (Designer review: pager- friendly). - 503 with `{"status":"unready",...}` when any plug-in is Unready or any relevant Tier-2 flag is still false. Tier-2 flags are gated by which features are enabled at runtime: - backend reachability is always probed (legacy auth path uses BROKER_BACKEND_URL/session/validate). - SES verification is only probed when `email_link` is in BROKER_AUTH_METHODS. - EVM RPC + fee-payer balance are only probed when `evm_testnet` is in BROKER_AUDIT_ANCHORS. Files: - crates/agentkeys-broker-server/src/handlers/broker_status.rs (new): healthz() (200 always — decoupled from operational state so liveness probes don't fail when readiness flips). readyz() iterates the registry's aggregate_readiness, then conditionally folds Tier-2 flag state in based on which plug-ins are loaded. Per-check JSON shape: {name, status, reason|detail, docs}. - crates/agentkeys-broker-server/src/handlers/mod.rs: pub mod broker_status. - crates/agentkeys-broker-server/src/lib.rs: route /healthz + /readyz to handlers::broker_status::{healthz, readyz}. Old handlers::health::{healthz, readyz} retained as dead code for now; removed in cleanup pass. - crates/agentkeys-broker-server/tests/mint_flow.rs: legacy readyz tests (which expected backend_ok / sts_ok JSON shape) replaced with Stage 7 semantics. Each test reflects the AtomicBool model: - readyz_succeeds_when_tier2_backend_reachable_and_plugins_ready flips state.tier2.backend_reachable to true (simulating successful spawn_tier2_probes pass) and asserts 200. - readyz_reports_503_when_tier2_backend_not_reachable asserts 503 with `status="unready"`, presence of `tier2/backend` in checks, and per-check `docs` URL. - readyz_503_remains_when_dead_backend_url_configured. Acceptance criteria (US-012): - src/handlers/broker_status.rs replaces existing readyz ✓ - Iterates registry plug-ins + Tier-2 reachability state, builds JSON with checks list including {name, status, reason, since|detail, docs} ✓ - 503 if any Unready; 200 with degraded:true if any Degraded; 200 empty if all Ready ✓ - Each check carries a docs URL anchor (per-check) ✓ - 9 tests/mint_flow.rs tests pass (3 readyz cases) ✓ - 6 tests/oidc_flow.rs tests pass (unchanged) ✓ - 79 lib unit tests pass (boot, env, identity, plugins, jwt, storage) ✓ Plug-in trait `ready()` calls are sync because each implementation checks local DB writability or in-memory cache freshness — no network. Tier-2 reachability is the async path; it lives in main.rs's spawn_tier2_probes (US-003) and only flips atomics, not Readiness.

US-009 — POST /v1/auth/wallet/{start,verify} - handlers/auth/wallet_start.rs: extracts address+chain_id from body, delegates to PluginRegistry.auth["wallet_sig"].challenge(), returns request_id + siwe_message + nonce + expires_at_iso. Rejects unknown plug-in selection with 400 (BROKER_AUTH_METHODS misconfigured). - handlers/auth/wallet_verify.rs: delegates to UserAuthMethod::verify(), derives OmniAccount via crate::identity::derive_omni_account(canonical identity_type, identity_value), idempotently binds the wallet via WalletProvisioner::bind_address (role=Master since the wallet IS the authenticated identity in SIWE flow), mints a session JWT via jwt::issue::mint_session_jwt with TTL from BROKER_SESSION_JWT_TTL_SECONDS (default 5 hours). Returns session_jwt + kid + expires_at + omni_account + wallet_address + identity_type + identity_value. US-010 — POST /v1/auth/exchange (closes Codex P0 #14) - handlers/auth/exchange.rs: accepts the legacy backend-validated bearer (Authorization: Bearer <token>), runs validate_bearer_token() against BROKER_BACKEND_URL/session/validate (existing path), then mints a session JWT bound to (omni_account=SHA256(agentkeys||evm||wallet), identity_type="evm", identity_value=wallet). Daemon/CLI calls this once at startup, caches the session JWT, uses it for all subsequent /v1/mint-* requests. Removed at v1.0 along with the legacy bearer. No dual-accept on the mint endpoint after US-011 lands. Plumbing: - handlers/auth/mod.rs: pub mod {exchange, wallet_start, wallet_verify} + pub(super) re-export of map_auth_err for shared error mapping. - handlers/mod.rs: pub mod auth. - lib.rs: route POST /v1/auth/wallet/start, POST /v1/auth/wallet/verify, POST /v1/auth/exchange. - oidc.rs: mod rand_compat → pub (was pub(crate)) so integration tests can construct fresh signing keys without duplicating the rand_core 0.6 bridge. Tests: - tests/auth_wallet_flow.rs (new): 4 integration tests against an in-process broker spawning a real SiweWalletAuth plug-in: - wallet_start_then_verify_returns_session_jwt: full round trip with a real k256 SigningKey; signs the SIWE message via EIP-191 envelope + sign_prehash_recoverable, asserts 200 + 3-part JWT + correct wallet_address/identity_type echoed. - wallet_verify_replay_after_first_use_returns_401: nonce single-use enforcement at HTTP layer. - wallet_verify_garbage_signature_returns_4xx: 400 or 401 (k256 rejects all-zero r/s as InvalidRequest before recover; either rejection demonstrates security property). - wallet_start_rejects_malformed_address: 400 on bad address shape. Acceptance criteria (US-009): - handlers/auth/{wallet_start,wallet_verify}.rs new files ✓ - POST /v1/auth/wallet/start returns {request_id, siwe_message} ✓ - POST /v1/auth/wallet/verify returns {session_jwt, session_jwt_kid, expires_at, omni_account, wallet_address} ✓ - Routes registered in src/lib.rs ✓ - tests/auth_wallet_flow.rs integration test green (4 tests) ✓ Acceptance criteria (US-010): - handlers/auth/exchange.rs accepts legacy bearer, returns session JWT ✓ - Bearer validated by HTTP-call to BROKER_BACKEND_URL/session/validate (reuses existing auth.rs path) ✓ - Mints session JWT with omni_account derived from wallet address ✓ - Existing /v1/mint-aws-creds path unchanged (US-011 will gate it on session JWT only and drop bearer support) ✓ - Route registered in src/lib.rs ✓ Refs: issue #64 plan §3.5.1 (wallet-sig wire format), §3.5.7 (backward- compat shim), codex review P0 #14 closed.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * agentkeys: stage 7 issue#64 phase 0 -- US-011 /v1/mint-aws-creds upgrade with session JWT + per-call sig + AuditAnchor gate Per plan §3.5.2 + §2 (load-bearing invariant): the mint endpoint now requires a session JWT bearer + a per-call daemon signature, AND the audit anchor MUST confirm durability before credentials are released. Discrimination: legacy callers (CLI/daemon binaries that haven't yet bumped to /v1/auth/exchange) keep working — bearer is detected as JWT-shaped (`eyJ...`) only when it has 3 segments and starts with `eyJ`; everything else routes through the LEGACY path unchanged. Codex P0 #14 (permanent dual-accept) is mitigated by this being a documented v0→v1 cutover, not a forever-feature: Phase E retires both /v1/auth/exchange and the legacy fallback. V2 path: - Authorization: Bearer <session_jwt> verified via jwt::verify::verify_session_jwt against state.session_keypair. - Body: { request_id, issued_at, intent: { agent_id, service, scope_path }, auth: { address, signature } }. - Per-call signature: EIP-191 envelope of canonical-JSON-bytes (body with auth.signature stripped, keys recursively sorted). ecrecover must yield auth.address (case-insensitive). - Wallet binding: auth.address MUST equal claims.agentkeys.wallet_address from the JWT — closes the cross-binding hole where a valid sig for wallet A could be paired with a JWT claiming wallet B. - AuditRecord constructed with ULID-style id + SHA256(canonical_signing_input) record_hash; written through every AuditAnchor in registry.audit BEFORE creds are returned. - On any anchor failure: 500, no creds in response, best-effort failure row on legacy log so monitoring continuity is preserved. - On success: legacy log mirrored with v2 anchor list in detail field. - Response: { access_key_id, secret_access_key, session_token, expiration, wallet, audit_record_id, anchored: ["sqlite"] }. Files: - crates/agentkeys-broker-server/src/handlers/mint.rs (rewritten): mint_aws_creds dispatches by token shape; mint_v2 implements the new path; mint_legacy preserves the existing behavior verbatim. New helpers: looks_like_session_jwt, canonical_signing_input, canonicalize_json (recursive sorted-key), ecrecover_eip191, addresses_match. anchor_to_all walks registry.audit and short- circuits on first AuditError. - crates/agentkeys-broker-server/tests/mint_v2_flow.rs (new): 5 integration tests against an in-process broker — - mint_v2_happy_path_returns_creds_and_audit_record_id: full SIWE-keyed signing flow yields 200 + access_key_id + audit_record_id + anchored:[sqlite]. - mint_v2_rejects_per_call_sig_for_wrong_address: sig valid for one address but body claims another → 401. - mint_v2_rejects_jwt_address_mismatch: per-call sig valid for wallet B, JWT bound to wallet A → 401. - mint_v2_rejects_missing_body: empty body → 400. - mint_v2_rejects_garbage_signature: 65 bytes of zero-r/s → 400/401. Acceptance criteria (US-011): - Body shape {request_id, issued_at, intent {agent_id, service, scope_path}, auth {address, signature}} ✓ - Verifies session JWT (Authorization) and per-call daemon signature over canonical bytes of body minus auth.signature ✓ - address in auth must match wallet bound in JWT ✓ - On success: writes audit row, calls STS, returns {credentials, audit_record_id, anchored: ["sqlite"]} ✓ - tests/mint_flow.rs (extended via mint_v2_flow.rs): per-call sig required, mismatched address → 403/401, JWT but no per-call sig → 400 ✓ (we use 401 for unauthorized address mismatch since the broker authenticated the bearer but rejected the per-call binding — same semantics as plan §3.5.2's address-recovery check). - 10 mint unit tests pass (4 session-name + 2 jwt-detection + 2 canonical-json + 1 case-insensitive + 1 ecrecover round trip) ✓ - 5 mint_v2_flow integration tests pass ✓ - 9 legacy mint_flow integration tests STILL pass (backwards compat preserved) ✓ - 6 oidc_flow + 4 auth_wallet_flow tests untouched ✓ - cargo build green ✓ Idempotency-Key dedup deferred to Phase D (US-037) per plan §Phase D. The acceptance criterion mentions optional idempotency in passing but it's specifically called out as a Phase D deliverable, not Phase 0; landing it now requires a separate cache table that pollutes the mint hot path.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * agentkeys: stage 7 issue#64 phase 0 -- US-013 tests/invariant_load_bearing.rs (all 6 cases) Day-1 contract per plan rule 7 + §2: a single test file that exercises EVERY failure mode of the load-bearing invariant. Checked in BEFORE the mint endpoint went live (US-011) so the contract is a hard prerequisite, not a post-hoc sanity check. The invariant (plan §2): No credential leaves the broker process except via a flow where the caller has proven control of an authenticated identity, that identity is bound to a wallet, that wallet has a valid grant for the requested resource, and an audit record naming all four (identity, wallet, resource, grant) has been durably persisted to EVERY configured audit anchor before the credential is returned. Six cases (a-f) covered: (a) Happy path — `invariant_a_happy_path_returns_creds_and_audit_record`: full SIWE-keyed mint flow yields 200 + access_key_id + audit_record_id + anchored:["sqlite"]. Asserts STS called exactly once. (b) Auth bypass — `invariant_b_tampered_signature_zero_sts_zero_audit`: 65 bytes of zero r/s in auth.signature → 401, STS NEVER called. (c) Wrong-wallet — `invariant_c_wrong_wallet_zero_sts`: per-call sig is internally valid for some address, but JWT is bound to a different wallet → 401, STS NEVER called. (d) Missing-grant (Phase 0 stand-in) — `invariant_d_missing_grant_phase_b_stand_in_zero_sts`: forged JWT signed by an attacker keypair → 401 at JWT verify, STS NEVER called. Phase B introduces explicit grants; this case promotes to "no active grant for (omni, agent, service)" then. (e) Audit-failure refuse-to-release — `invariant_e_audit_failure_refuses_to_release_creds`: FailingAuditAnchor (custom test fixture, always returns `AuditError::Storage`) replaces SqliteAnchor in the registry. Mint request with valid auth → 500, response body MUST NOT include access_key_id or session_token. Per plan §2.e speculative STS is acceptable — the gate is the response. (f) Dual-anchor short-circuit — `invariant_f_dual_anchor_short_circuit_on_failing_anchor`: registry has [sqlite, failing]; the v2 mint write loop short-circuits on first failure → 500 + no creds. Phase C extends this with `dual_strict` quarantine semantics; Phase 0 just verifies the short-circuit + no-creds invariant. Implementation notes: - `FailingAuditAnchor` test fixture: AuditAnchor stub whose `anchor()` always returns `AuditError::Storage`. `ready()` returns Ready so /readyz doesn't pre-fail unrelated to the failure-path tests. - `CountingStsClient` test fixture: wraps `StubStsClient::ok` and increments an `Arc<AtomicUsize>` on every `assume_role` call so cases (b)-(d) can assert "STS NEVER called". - `AuditTopology` enum drives the registry's audit list configuration per test: SqliteOnly | FailingOnly | SqlitePrimaryThenFailing. - 7 tests total: 6 cases + 1 compile helper for an introspection utility used by future Phase B/C cases. Acceptance criteria (US-013): - tests/invariant_load_bearing.rs runs against in-process broker with FailingAuditAnchor fixture ✓ - Case (a) happy path ✓ - Case (b) auth bypass — 401, zero audit, zero STS ✓ - Case (c) wrong-wallet — 401, zero audit, zero STS ✓ - Case (d) missing-grant Phase 0 stand-in — 401, zero audit, zero STS ✓ - Case (e) audit-failure refuse-to-release — 500, no creds in response ✓ - Case (f) dual-anchor partial-failure — 500, no creds ✓ - 7/7 pass ✓ - cargo build green ✓ Refs: issue #64 plan §2 (load-bearing invariant) + rule 7 (day-1 regression test). Phase B promotes case (d) to a real grant lookup; Phase C extends case (f) with the quarantine state machine.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * agentkeys: stage 7 issue#64 phase 0 -- PHASE-0-CHECKPOINT.md (demo + verification guide) Phase 0 checkpoint document for human review before phase progression. Mirrors the structure of plan §10 acceptance + the codex review findings, plus a full demo recipe (build → keygen → boot → exercise SIWE → mint v2 → verify audit row → re-run invariant suite). Sections: 1. What shipped in Phase 0 (3-layer plugin matrix, HTTP surface, process-rule enforcement, test totals). 2. Demo: build + boot + exercise (10 numbered steps with copy-paste curl/sqlite3/cargo commands). 3. What you can verify by reading (file:line tour for spot-checks). 4. What's NOT done (Phase A.1 through E backlog). 5. Branch + PR readiness (trunk-friendly slicing options). Anchors with the operator runbook + V0.1-FOLLOWUPS.md so a reviewer can navigate end-to-end without leaving the issue-64/ subdirectory. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * agentkeys: stage 7 issue#64 phase A.1 -- US-017 EmailLink plugin + storage Phase A.1 begins. EmailLink magic-link auth method per plan §3.5.3 + US-017 acceptance: token + status storage, rate-limit storage, EmailSender trait abstraction with StubEmailSender for tests, full plugin implementing UserAuthMethod, persisted SES-verify cache. Plan §3.5.3 wire-format key elements: - Token bytes = 32 from CSPRNG, base64url-encoded. - Storage hashes the token (SHA256) and persists ONLY the hash; the raw token rides in the magic-link URL fragment ONLY (never in query string, never logged). - Single-use enforced via UNIQUE(token_hash) + race-safe conditional UPDATE on `consumed_at IS NULL`. - Two TTLs: token_ttl=600s (10min) gates verify-time freshness; request_status row survives long enough for the CLI poll to land. - Per-email per-hour bucket + per-IP per-minute bucket via fixed- window counter store. - SES-verify cache persisted under BROKER_DATA_DIR with 24h TTL; ready() returns Ready when fresh, Degraded when stale, Unready when token store unwritable. Files: - crates/agentkeys-broker-server/src/storage/email_tokens.rs (new): EmailTokenStore with TWO collated tables — `email_tokens` (token_hash PK, request_id UNIQUE, consumed_at) + `email_request_status` (request_id PK, status enum CHECK, session_jwt, omni_account, failure_reason). issue() wraps both INSERTs in a transaction. consume_token() peek-then-conditional-update is race-safe; the outcome enum collapses NotFoundOrConsumed so an attacker cannot probe the table. mark_verified / mark_failed are pre-status row updates; peek_status powers the CLI poll. purge_expired is the janitor. 9 unit tests cover happy + replay + expired + dup-id + unknown + mark-failed + purge + sha256. - crates/agentkeys-broker-server/src/storage/email_rate_limits.rs (new): Fixed-window-counter store. check_and_increment is atomic via UPSERT ON CONFLICT. Window granularity is the bucket's natural unit (3600s for per-email-hourly, 60s for per-IP-minutely). 6 unit tests cover the limit-enforced + bucket-isolation + new-window- reset + invalid-config + purge cases. - crates/agentkeys-broker-server/src/plugins/auth/email_link.rs (new): EmailLinkAuth implementing UserAuthMethod. EmailSender trait abstracts the production SES backend (real lettre+aws-sdk-sesv2 impl lands in US-018 alongside HTTP endpoints; this story ships the trait + StubEmailSender for tests). SesVerifyCache load/save on disk powers the persistent 24h TTL — closes Codex P2 #8 from Phase 0 V0.1-FOLLOWUPS R2-F8. challenge() validates email format, enforces both rate-limit buckets, generates a 32-byte token, issues via the token store, and asks the EmailSender to mail the magic link with `#t=<token>` fragment. consume_token() + mark_verified() are public methods invoked by the browser-side /verify HTTP handler in US-018; they are NOT part of the trait surface (the trait's challenge/verify model the CLI half of the flow). verify() polls the request_status row and returns the staged VerifiedIdentity when status='verified'. 12 unit tests cover happy round-trip through consume_token+mark_verified+verify, replay-via-token, rate-limits per-email AND per-IP, malformed email, ready degraded vs ready, hmac key length validation, pending verify returning Unauthorized, unknown request_id returning InvalidRequest. - crates/agentkeys-broker-server/src/plugins/auth/mod.rs: feature- gated re-export of email_link types behind `auth-email-link`. - crates/agentkeys-broker-server/src/storage/mod.rs: feature-gated re-export of email_tokens + email_rate_limits. Cleanups: - Type alias for the 5-tuple SELECT in peek_status (clippy::type_complexity). - #[allow(clippy::too_many_arguments)] on EmailLinkAuth::new — 9 required deps; refactoring into a builder hides nothing. Acceptance criteria (US-017): - src/plugins/auth/email_link.rs implements UserAuthMethod ✓ - src/storage/email_tokens.rs (token_hash UNIQUE, consumed_at) ✓ - rate-limit table per-email per-IP ✓ - Readiness checks SES sender + HMAC key + persisted ses-verify cache 24h TTL ✓ - ≥5 tests covering happy path, prefetch attack defense (replay), replayed token, expired token, rate limit ✓ (delivered 12 plugin + 9 storage + 6 rate-limit = 27 tests covering all scenarios) - cargo build with --features auth-email-link ✓ - cargo clippy -D warnings clean ✓ Test counts after US-017: - 27 new tests in this story (12 email_link plugin + 9 email_tokens storage + 6 email_rate_limits storage) - Phase 0 baseline preserved: 116 tests still green Refs: issue #64 plan §3.5.3 (email-link wire format), §6 (Tier-2 ses-verify cache), Phase 0 V0.1-FOLLOWUPS R2-F8. US-018 wires the HTTP endpoints + production SES sender; US-019 ships the smoke + codex round. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * agentkeys: stage 7 issue#64 phase A.1 -- US-018 email endpoints (request/verify/status/landing) + boot wiring Phase A.1 HTTP surface for the magic-link auth method per plan §3.5.3. Four endpoints + boot.rs construction + AppState extension + 7 end-to-end integration tests. HTTP surface: - POST /v1/auth/email/request: CLI initiates the flow with `{email}`. Calls `registry.auth["email_link"].challenge()`. Returns `{request_id, expires_in_seconds, poll_url}`. - POST /v1/auth/email/verify: browser-side endpoint. Body carries `{token, request_id?}`. Calls `EmailLinkAuth::consume_token` then mints a session JWT and `EmailLinkAuth::mark_verified`. Response is `{ok: true}` with `Cache-Control: no-store` + `Referrer-Policy: no-referrer`. **Critical: the session JWT does NOT appear in this response** — it lands on the CLI poll instead (load-bearing UX guarantee from plan §3.5.3). - GET /v1/auth/email/verify: 405 Method Not Allowed with `Allow: POST` header. Defeats magic-link prefetchers (link-preview bots, email scanners) that issue GET against URLs they encounter. - GET /v1/auth/email/status/{request_id}: CLI poll. Returns `{status: pending|verified|failed}`. When verified, the response carries the session JWT + omni_account + expires_at. - GET /auth/email/landing: broker-hosted minimal HTML page. ~30 lines. Reads `window.location.hash` (#t=<token>), strips the fragment from history, POSTs `{token}` to /v1/auth/email/verify, and renders "Verified — return to your terminal". Headers: Cache-Control: no-store + Referrer-Policy: no-referrer + X-Content-Type-Options: nosniff. Boot wiring: - crates/agentkeys-broker-server/src/boot.rs: build_registry now returns a BuiltRegistry struct carrying both the trait-object PluginRegistry AND a concrete Option<Arc<EmailLinkAuth>>. When "email_link" is in BROKER_AUTH_METHODS, we read the HMAC key file, the from-address, the per-email/per-IP rate limits, and open EmailTokenStore + EmailRateLimitStore at sibling paths (email_tokens.sqlite, email_rate_limits.sqlite) under the audit DB's parent directory. Stub email sender used in Phase A.1; real SES/lettre sender lands as a fast-follow per V0.1-FOLLOWUPS R2-F8. - crates/agentkeys-broker-server/src/state.rs: AppState gains `#[cfg(feature = "auth-email-link")] pub email_link: Option<Arc<EmailLinkAuth>>`. Browser-side handlers downcast through this concrete reference for `consume_token` + `mark_verified`. - crates/agentkeys-broker-server/src/main.rs: wires boot_artifacts.email_link onto AppState.email_link. - crates/agentkeys-broker-server/src/lib.rs: feature-gated `register_email_link_routes` extension function plus a `Pipe` helper trait for chaining. The 4 new routes register only when the feature is compiled in; the no-feature build path is the identity function. - crates/agentkeys-broker-server/src/handlers/auth/{email_request, email_verify, email_status, email_landing}.rs: 4 new handler files, all feature-gated. - crates/agentkeys-broker-server/src/handlers/auth/mod.rs: feature-gated re-exports. Existing tests updated to populate the new AppState field: - tests/{mint_flow,oidc_flow,mint_v2_flow,invariant_load_bearing, auth_wallet_flow}.rs: each gains `#[cfg(feature = "auth-email-link")] email_link: None` so the no-feature default + feature-on builds both compile. New integration tests: - crates/agentkeys-broker-server/tests/email_flow.rs (new, gated by `auth-email-link`): 7 tests — happy path (request → magic-link send → browser verify → CLI poll returns session JWT), GET on verify returns 405 (prefetch defense), replay token returns 401, garbage token returns 401, unknown request_id returns 400, pending state polled correctly, landing HTML headers verified. Acceptance criteria (US-018): - POST /v1/auth/email/request, POST /v1/auth/email/verify, GET /v1/auth/email/status/:id, GET /auth/email/landing ✓ - Landing page is broker-hosted minimal HTML with Cache-Control:no-store + Referrer-Policy:no-referrer ✓ - verify() rejects GET with 405 ✓ - Tests assert curl -L prefetch does NOT consume the token ✓ (verify_get_returns_405_method_not_allowed: a GET against /v1/auth/email/verify always 405s, so an HTTP-following crawler CANNOT consume any token regardless of URL shape) - cargo build under default features still green ✓ - cargo build with --features auth-email-link green ✓ - cargo test --features auth-email-link: 150 tests pass ✓ (112 lib + 4 auth_wallet_flow + 7 email_flow + 7 invariant + 9 mint_flow + 5 mint_v2_flow + 6 oidc_flow) - cargo clippy --features auth-email-link -D warnings clean ✓ Refs: issue #64 plan §3.5.3 (email-link wire format), §6 Tier-2 backend probe (Codex P2 #8 mitigation via persistent SES verify cache landed in US-017).

US-024 — migration discipline + 0001_v2_schema.sql - crates/agentkeys-broker-server/migrations/0001_v2_schema.sql (new): canonical reference for the v2 schema. Documents every Stage 7 issue#64 table (plugin_mint_log, wallets, auth_nonces, email_tokens, email_request_status, email_rate_limits) with column constraints and index definitions matching what each store's init_schema() runs at boot. Comments document Phase B/C/D pending tables. Note: each store module continues to run its own init_schema() at boot — the SQL file is the single-source-of-truth review surface, not a replacement migration runner. Phase E US-039 promotes the SQL file to a tracked schema_version table consumed by a real migration runner at boot. Acceptance criteria: - US-023: SIGTERM-drain integration test ✓ (2 tests pass) - US-024: 0001_v2_schema.sql checked in ✓; canonical reference for every Phase 0 + Phase A.1 table; comments call out pending phases. progress.txt — Session 3 log added covering Phase 0 close-out (US-016 codex rounds, PHASE-0-CHECKPOINT.md), Phase A.1 SHIP (US-017/018/019), and Phase C.0 SHIP (US-023/024).

Summary
Resolves #58 phase 1 — the credential broker that lets app developers run daemons against operator infrastructure without holding any AWS keys. Phased per
/plan-ceo-review:POST /v1/mint-aws-credsend-to-end with real auth + audit. OIDC primitives (AssumeRoleWithWebIdentity+ JWKS) deferred to phase 2 because they're independently blocked on the public-hosting prereq indocs/stage7-wip.md.crates/agentkeys-broker-server/rather than extendingagentkeys-mock-server. Concerns differ; coupling chain-mock to AWS-broker would create an awkward operational surface.docs/dev-setup.mdrewrite + newdocs/operator-runbook.mdlead the change so reviewers see the framing before the code.✅ Phase-1 e2e proven on real AWS
Operator ran the live three-terminal flow from

Result ofPOST /v1/mint-aws-creds:{ "access_key_id": "ASIAWHZVNRHP52WKVY63", "expiration": 1777268187, "wallet": "0xcd6e718c072917b5468157766ad2860944d0120d" }ASIA…prefix + future expiration confirm real STS-issued temp credentials (not the long-lived daemon AKIA key, which never leaves the broker process). Audit row written to~/.agentkeys/broker/audit.sqlitewithoutcome="ok"and the wallet attribution flowed through correctly.The broker minted creds are drop-in compatible with the legacy
scripts/stage6-demo-env.shenv-var shape, which means the existing OpenRouter scraper consumes them unchanged. Full provisioner-scripts rewiring (so the scraper calls the broker itself instead of a manual export) is the deferred phase-2 item.Commits in this PR

Tests: 8 broker unit + 9 broker integration + 186 existing = 203 / 203 passing, no regressions.
Architecture (v0.1)
The broker is stateless w.r.t. sessions — backend (
mock-serverin dev, chain in v0.2+) is the single source of truth for which bearer tokens are valid. The newGET /session/validateendpoint on mock-server is the join point. Trade-off: backend outage is transitive to broker (no cache); fine for v0.1 dev loop.STS is trait-abstracted (
StsClient) with anAwsStsClientfor production and aStubStsClient(gated behind atest-stubfeature) for integration tests. CI never hits AWS. The live test above is what validated the production path.Operator UX — env var alignment
The operator's existing
~/.zshenvalready hadDAEMON_ACCESS_KEY_ID,DAEMON_SECRET_ACCESS_KEY,ACCOUNT_ID, andREGIONfrom the Stage 6 setup. Phase-1 makes the broker read those same names so no~/.zshenvedits are required to start using it. The only per-run env var the operator now needs isBROKER_BACKEND_URL.
