Remove the push-to-main trigger from .github/workflows/deploy.yaml so merges
no longer deploy automatically; deploys now run only via the Actions "Run
workflow" button (workflow_dispatch). No job content, permissions, or
reusable-workflow inputs changed. README and the auth deploy runbook updated
to match.
* ci: add standard labeler caller (INFRA-136)
Adds the org standard callable-labeler thin caller, missing on this repo
(present on 26/28 repos). All three permission grants are load-bearing;
omitting one causes a silent startup_failure.
* Update labeler workflow to specific commit
vitest and @vitest/coverage-v8 share a strict peer dependency. Bumping them
in separate Dependabot PRs breaks npm ci. Grouping them ensures they stay
in lockstep.

Upgrade vitest to 3.2.7 across the monorepo, override vite to 6.4.3 for
the high-severity fs.deny advisory, and add weekly grouped Dependabot for
npm workspaces and GitHub Actions.
* Phase 2a: Cognito auth substrate (CDK) + pre-token & group-sync Lambdas
Stands up the real AWS auth broker the servers already validate against
(SH_MCP_ENV=aws), surface-agnostic. Nothing deployed yet (gated on Google
secrets); CI synthesizes the stack.
infra/ — root CDK app, stack sh-mcp-auth:
- Cognito user pool, ESSENTIALS feature plan (required for the V2 pre-token
trigger), Google external OIDC IdP (client_id/secret resolved from Secrets
Manager at deploy via CFN dynamic reference, never inlined).
- Resource servers + per-tier app clients whose AllowedOAuthScopes ARE the
trust-tier boundary: ops=(read,tasks), exec=(ops+gmail/calendar, NO finance),
finance=(finance:read ONLY, 15-min access TTL). offline refresh 30d.
- Cognito groups sh-mcp-ops/-assistant/-finance/-admin.
- sync-state + deny-list DynamoDB tables (overrideLogicalId pinned so a future
refactor cannot replace+drop them; deny-list TTL attr 'expiresAt').
- Least-priv IAM (no wildcard action/resource; Google SA secret grant scoped to
the one secret), arm64 Lambdas, explicit 60-day log groups, alarms on the
seahaven-alarm-topics CMK (ALARM-state actions only, two-alarm group-sync).
auth/pre-token-gen — SUPPRESS-ONLY V2 Lambda. Maps Cognito group entitlement to
scopesToSuppress; NEVER scopesToAdd a tier scope (AllowedOAuthScopes stays the
ceiling). Reads last_successful_sync; fail-closed to base ops:read when stale.
auth/group-sync — mirrors Google Group membership into Cognito groups every 5 min
(jose-signed SA JWT -> Directory API, no googleapis dep); writes the freshness
marker ONLY on full success so a partial failure keeps the pre-token Lambda
failing closed.
37 new tests (suppress-only policy, fail-closed, reconcile diff, 16 CDK
assertions incl. Essentials/V2/per-client-scope/no-wildcard-IAM). 448 total pass;
tsc -b + infra typecheck + cdk synth + prettier clean; CI run-cdk-synth re-enabled.
App-client callback URLs are a context placeholder pending the surface decision.
Confluence map (1540098) + project memory updates owed once this deploys.
* Phase 2a: harden auth substrate per security-review + IAM cross-review
Both mandatory gates run on the 2a diff. GPT-4.1 IAM/Lambda cross-review: the
suppress-only invariant is now an executable fail-closed guard (a future edit
that sets scopesToAdd throws → no token minted). /sh-security-review fan-out +
proof-or-kill verifier: PASS (0 confirmed critical/high). The verifier refuted
the two "high" candidates (the email-case revocation "bypass" is symmetric — the
add path uses the same lowercasing filter, so an un-removable user could never
have been added; the empty-directory purge is a non-200 throw → stale marker →
fail closed). Three confirmed findings remediated:
- C2 (deny-list was inert): the sh-mcp-deny-list table was provisioned and
documented as "hard revocation" but no code read it. The pre-token Lambda now
reads it on every mint (DENY_LIST_TABLE env + grantReadData) and strips a
deny-listed sub to NO tier scopes, ahead of the next group sync. Fail-OPEN on
a DDB read error (logs deny_list_read_failed) so a blip can't lock everyone
out — group membership + its fail-closed 30-min window stay authoritative.
- C5 (finance 30-day refresh nullified the 15-min access TTL): refresh window is
now per-tier; finance caps at 8h, ops/exec keep 30d.
- C7 (nested Google-group members silently dropped): listGroupMembers now sets
includeDerivedMembership and skips non-USER rows, honoring the documented
"nested resolved" contract instead of pushing a phantom group address.
Also corrects the sync.ts comment that overstated fail-closed as instantaneous
(it is bounded by MAX_SYNC_AGE_MS). +8 tests (deny-list unit, hard-revocation
handler path, finance refresh window, deny-list env wiring); 456 pass. tsc -b,
cdk synth, prettier, eslint all clean.
