From de34e133e3f97c97ce59b3bbf712fad4a109798a Mon Sep 17 00:00:00 2001 From: Viktor Shcherbakov Date: Thu, 7 May 2026 14:52:45 +0200 Subject: [PATCH 1/2] =?UTF-8?q?feat(auth):=20M1=20multi-tenant=20auth=20fo?= =?UTF-8?q?undation=20=E2=80=94=20publishers,=20four-token=20model,=20HMAC?= =?UTF-8?q?=20webhooks?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the single shared MURMUR_TOKEN with a per-publisher namespace and four-token model (admin, runner, webhook_signing, subcommand_bearer). Existing demo deploy continues to work via env-grandfathered MURMUR_TOKEN. Schema (migration 0002): - publishers, publisher_tokens, publisher_secrets, publisher_audit_events - pipelines.publisher_id (NOT NULL DEFAULT pub_demo_seed); back-fills existing rows - Demo seed inserted in-migration so the FK back-fill default is satisfied Auth zoning (src/server.ts): - POST /publishers gated by MURMUR_BOOTSTRAP_TOKEN - /pipelines*, /runs*, /publishers/me* gated by publisherAuth(db) + per-route requireKind - /work*, /mcp* keep legacy bearerAuth (agent plane unchanged in M1) Cross-publisher isolation: - pipelines UPSERT scoped via ON CONFLICT WHERE publisher_id; cross-publisher slug collision returns 409 - runs/runs-list JOIN through pipelines.publisher_id; cross-publisher reads → 404 Per-publisher webhook bearer: - Webhook delivery resolves the run's publisher's subcommand_bearer; demo seeded to MURMUR_TOKEN preserves jobseek's accept handler. Cross-publisher leak of MURMUR_TOKEN closed. - Additive X-Murmur-Signature: t=,v1= header; bearer retained for backward compat (drop in M10). task_tool dispatch: - Resolves the run's publisher's subcommand_bearer (via JOIN on LOOKUP_CLAIM_SQL); per-tenant credential, MURMUR_TOKEN never leaks to subcommand endpoints of hostile publishers. Boot-seed (src/db/bootstrap.ts): - Idempotent demo publisher seed; grandfathers MURMUR_TOKEN as kinds_json=["admin","runner"]; subcommand_bearer rotated in lockstep with MURMUR_TOKEN; webhook_signing_secret generated random. Admin API (POST /publishers, GET/PATCH /publishers/me, tokens rotate/delete, audit) with rotation atomicity and kind verification on revoke (DELETE /tokens/runner/ can no longer revoke an admin row). Documentation in docs/auth.md with Node + Python verifier samples.

Publishers that haven't migrated to verify +HMAC yet continue to accept on the bearer — both headers are sent +additively. The legacy bearer is dropped in M10 cutover. + +## Demo publisher (jobseek) + +The 0002 migration seeds `pub_demo_seed` as a placeholder publisher +row.
