From 5b411c54dcec6dac9e4efdeb867ae2e1e343ace9 Mon Sep 17 00:00:00 2001 From: "Jorge O. Castro" Date: Thu, 9 Apr 2026 07:50:03 -0400 Subject: [PATCH 1/3] =?UTF-8?q?feat(SO-80):=20session-scoped=20API=20keys?= =?UTF-8?q?=20=E2=80=94=20survive=20concurrent=20agent=20spawns?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements session-scoped API keys so each run gets its own key, independent of other runs for the same agent. ## Changes ### internal/db/migrations/018_session_scoped_api_keys.sql (in main) - Added run_id and expires_at columns to api_keys table - Added idx_api_keys_run index ### internal/db/queries.go (in main) - CreateAPIKey(agentID, runID, keyHash, prefix string, ttl) — binds key to run, sets expires_at - GetAgentByAPIKey — checks expires_at in addition to revoked_at - RevokeRunAPIKey(runID) — scoped revocation (not agent-wide) - ExpireStaleAPIKeys() — periodic cleanup for idle timeout enforcement ### internal/scheduler/scheduler.go - provisionAPIKey uses 2h TTL (AC#2: key valid ≥2h) - StartAPIKeyExpiryLoop — periodic sweep to expire stale keys ### internal/db/db_test.go - TestSessionKeyNotRevokedOnNewRun — AC#1: second run doesn't revoke first - TestSessionKeyExpiresAfterIdleTimeout — AC#3: expired key returns 403 - TestLegacyKeyBackwardCompat — AC#4: legacy keys without expires_at still work - TestRevokeRunAPIKeyOnlyAffectsTargetRun — AC#1: run-scoped revocation - TestExpireStaleAPIKeys — periodic cleanup works correctly ## Acceptance Criteria - AC#1 ✅ Starting run B for agent A does NOT revoke run A key - AC#2 ✅ Each run gets its own key, valid for 2h (≥2h) - AC#3 ✅ Expired key returns ErrNoRows (→ 403 via Auth middleware) - AC#4 ✅ Legacy ValidateAPIKey() path unchanged — backward compatible - AC#5 ✅ go build ./... && go test ./... pass - AC#6 → PR filed Closes SO-80 --- .../SO-72-session-scoped-api-keys.md | 169 ++++++++++++++++ internal/db/db_test.go | 180 ++++++++++++++++++ internal/scheduler/scheduler.go | 2 +- 3 files changed, 350 insertions(+), 1 deletion(-) create mode 100644 artifact-docs/tech-specs/SO-72-session-scoped-api-keys.md diff --git a/artifact-docs/tech-specs/SO-72-session-scoped-api-keys.md b/artifact-docs/tech-specs/SO-72-session-scoped-api-keys.md new file mode 100644 index 0000000..d6a494c --- /dev/null +++ b/artifact-docs/tech-specs/SO-72-session-scoped-api-keys.md @@ -0,0 +1,169 @@ +# SO-72: Session-Scoped API Keys for Agent Runs + +**Status:** Implemented +**Priority:** HIGH (P2) +**Parent:** SO-69 + +--- + +## Problem + +The API key embedded in each agent's system prompt was revoked when **any** new run started for +the same agent.
