From f76d356e75995c01face7038a30f98168e232529 Mon Sep 17 00:00:00 2001 From: Molecule AI Backend Engineer Date: Fri, 17 Apr 2026 01:19:51 +0000 Subject: [PATCH 001/125] feat(hermes): plumb response_format=json_schema for structured output (#498) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds response_format support to HermesA2AExecutor so callers can request structured JSON output via the OpenAI-native response_format parameter. Changes: - _validate_response_format(): validates type (json_schema/json_object/text) and required sub-fields; returns None if valid, error message if invalid - HermesA2AExecutor.__init__: new response_format kwarg, stored as _response_format - execute(): validates before API call — invalid schema enqueues error and returns early without hitting Hermes API; valid and non-None adds response_format= to create_kwargs; None omits the field entirely Tests (12 new): - _validate_response_format: all valid types, invalid type, missing fields - constructor stores response_format correctly - valid response_format forwarded to API call - response_format omitted when None (no key in call kwargs) - invalid schema → error message enqueued, API not called Closes #498 Co-Authored-By: Claude Sonnet 4.6 --- workspace-template/hermes_executor.py | 101 +++++++++++- .../tests/test_hermes_executor.py | 152 +++++++++++++++++- 2 files changed, 246 insertions(+), 7 deletions(-) diff --git a/workspace-template/hermes_executor.py b/workspace-template/hermes_executor.py index 07aa4648..06a2eea0 100644 --- a/workspace-template/hermes_executor.py +++ b/workspace-template/hermes_executor.py @@ -26,6 +26,22 @@ Hermes 3 / unknown models No ``extra_body`` is sent.

Subject: [PATCH 005/125] feat(channels): add Discord adapter (#625) Implements DiscordAdapter conforming to the ChannelAdapter interface, using Discord Incoming Webhooks for outbound messages and the Interactions endpoint for inbound slash commands. Changes: - platform/internal/channels/discord.go: DiscordAdapter + splitMessage helper (Discord enforces 2000-char limit; long messages are split at newline/space boundaries). ParseWebhook handles type-1 PING (returns nil so the router layer can respond), type-2 APPLICATION_COMMAND, and type-3 MESSAGE_COMPONENT payloads. ValidateConfig rejects non-discord webhook URLs (SSRF guard matches Slack pattern). - platform/internal/channels/discord_test.go: 20 unit tests covering Type/DisplayName, ValidateConfig (valid + 5 invalid cases), SendMessage error paths, ParseWebhook (PING / slash command / DM user / unknown type / invalid JSON), StartPolling, GetAdapter registry lookup, ListAdapters inclusion, and splitMessage edge cases. - platform/internal/channels/registry.go: register "discord" adapter. - .env.example: document DISCORD_WEBHOOK_URL.

When the platform builds a messages array from multiple sources (base system prompt + workspace config + per-session override), the consecutive system entries at the front cause vLLM to reject or silently drop all but the first. Adds mergeSystemMessages() — a stateless pre-flight transform in the handlers package that collapses the uninterrupted leading run of {"role":"system"} entries into one, joining their content with "\n\n". Non-system messages between system messages are not touched; a single system message is returned as-is (no allocation). 10 unit tests cover: stacked merge, single-unchanged, no-system passthrough, three-message collapse, interleaved user (trailing system not merged), only-system-messages, empty slice, nil slice, non-string content, and assistant-leading passthrough.

hmac.compare_digest (Python) and hmac.Equal (Go) in ledger.py, verify.py, and audit.go to prevent timing oracle attacks (Fixes 1-6) - Increase PBKDF2 iterations from 100K to 210K in both ledger.py and audit.go — must match for cross-language verification (Fix 7) - Return chain_valid: null when offset > 0 (paginated views cannot verify a truncated chain; null means "not computed") (Fix 8) - Remove module-level AUDIT_LEDGER_SALT attribute from ledger.py; read the secret exclusively from os.environ inside _get_hmac_key() so the salt is not exposed in the module namespace (Fix 9) - Update tests: use monkeypatch.setenv/delenv instead of setattr on the removed AUDIT_LEDGER_SALT attribute; update testAuditKey helper to use 210K iterations; add TestAuditQuery_PaginatedOffsetReturnsNullChainValid - Fix migration 028: workspace_id column type TEXT → UUID to match workspaces.id UUID primary key All tests pass: 1043 pytest + 0 Go test failures.

Overwriting it redirected those tools to the build context, causing unpredictable failures. Renamed all 6 occurrences to RUNTIME_DIR. Bug 2: `docker build ... | grep` made grep's exit code (0=match, 1=no match) determine if the build succeeded, not docker's. Fixed by reading PIPESTATUS[0] immediately after the pipeline so docker's real exit code drives the SUCCESS/FAILED tracking.

Fix: introduce VALID_RUNTIMES allowlist and validate $1 against it before setting RUNTIMES. Any unlisted value now exits with a clear error message. The RUNTIMES array is populated from VALID_RUNTIMES when no argument is given, keeping the all-runtimes default path. shellcheck clean; $1 only appears inside the validated block.

This closes the proactive detection gap that left issue #85 (cron died silently 10+ hours) undetectable until users noticed missing work. Changes: - platform/internal/handlers/admin_schedules_health.go: new AdminSchedulesHealthHandler - GET /admin/schedules/health joins workspace_schedules + workspaces (excluding removed workspaces), computes status (ok|stale|never_run) and stale_threshold_seconds (2 × cron interval via scheduler.ComputeNextRun) - computeStaleThreshold() and classifyScheduleStatus() extracted as package-level helpers for direct unit testing - platform/internal/handlers/admin_schedules_health_test.go: 16 tests - Unit tests for computeStaleThreshold (5min/hourly/daily crons, invalid expr, invalid timezone) and classifyScheduleStatus (never_run/stale/ok/zero-threshold) - Integration tests via sqlmock: empty result, never_run classification, stale detection, ok status, DB error → 500, multi-workspace response, required JSON fields coverage - platform/internal/router/router.go: register GET /admin/schedules/health behind middleware.AdminAuth(db.DB), mirroring the /admin/liveness gate Closes #618 Co-Authored-By: Claude Sonnet 4.6 --- .../handlers/admin_schedules_health.go | 163 +++++++ .../handlers/admin_schedules_health_test.go | 446 ++++++++++++++++++ platform/internal/router/router.go | 27 +- 3 files changed, 625 insertions(+), 11 deletions(-) create mode 100644 platform/internal/handlers/admin_schedules_health.go create mode 100644 platform/internal/handlers/admin_schedules_health_test.go diff --git a/platform/internal/handlers/admin_schedules_health.go b/platform/internal/handlers/admin_schedules_health.go new file mode 100644 index 00000000..9310edb4 --- /dev/null +++ b/platform/internal/handlers/admin_schedules_health.go @@ -0,0 +1,163 @@ +package handlers + +import ( + "log" + "net/http" + "time" + + "github.com/gin-gonic/gin" + + "github.com/Molecule-AI/molecule-monorepo/platform/internal/db" + "github.com/Molecule-AI/molecule-monorepo/platform/internal/scheduler" +) + +// AdminSchedulesHealthHandler serves GET /admin/schedules/health — a cross-workspace +// schedule monitoring view gated behind AdminAuth.

Add Ed25519 verification via verifyDiscordSignature() before adapter.ParseWebhook() is called. The function reads r.Body, verifies Ed25519(pubKey, timestamp+body, X-Signature-Ed25519), then restores r.Body with io.NopCloser so ParseWebhook can still read the payload. The public key is resolved from the first enabled Discord channel's app_public_key config (plaintext — it is a public key and not in sensitiveFields) with a fallback to DISCORD_APP_PUBLIC_KEY env var; no key configured -> 401 (fail-closed). discordPublicKey() is the DB helper. MEDIUM (#659-2): discord.go SendMessage() wrapped http.Client.Do errors with %w, propagating the *url.Error which includes the full webhook URL (https://discord.com/api/webhooks/{id}/{token}) into logs and error responses. Replace with a static "discord: HTTP request failed" string.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit FIX 1: Cloudflare Artifacts routes (wsAuth POST/GET /artifacts, /fork, /token) were accidentally dropped when #618 modified router.go. Restored along with the handler and client packages that were already on main (#595/#641) but missing from this branch. FIX 2: Stray `audh := handlers.NewAuditHandler()` / `wsAuth.GET("/audit", ...)` block was added out-of-scope during #618 work. Removed — #594 (audit-ledger) is a separate merged PR and its routes live on main independently. Build: `go build ./...` clean. All 17 test packages pass.

Any unauthenticated caller could rename, change role, or update any workspace field of any workspace ID without credentials (zero auth + no ownership check). - Fix: register under wsAuth (WorkspaceAuth middleware) which (a) requires a valid bearer token and (b) validates the token belongs to the target workspace, providing auth + ownership in a single check. - Remove the now-redundant in-handler field-level auth block — the middleware is a strictly stronger gate. Dead code gone. - Remove unused `middleware` import from workspace.go. - Update tests: two tests that asserted the old in-handler 401 are replaced by TestWorkspaceUpdate_SensitiveField_AuthEnforcedByMiddleware (documents that auth is now at the router layer); cosmetic-field test renamed.

E2E calls test-token to get its first admin bearer → 401 5. All subsequent E2E calls fail → EVERY open PR CI blocked The test-token handler already has its own production guard (TestTokensEnabled returns false when MOLECULE_ENV=prod). That's sufficient — AdminAuth was defence-in-depth but broke the only bootstrap path in dev/CI environments. This has been blocking CI for 6+ cycles, stalling 4 PRs (#650, #651, #696, #701) and masking as 'flaky E2E Postgres timeout' until root-cause analysis this cycle.
