refactor: split 4 oversized handler files into focused sub-files by airenostars · Pull Request #1363 · EnterOS-AI/enter-os-core

airenostars · 2026-04-21T09:51:30Z

Summary

Split org.go (1099 lines) into org.go (349) + org_import.go (490) + org_helpers.go (290)
Split mcp.go (1001 lines) into mcp.go (387) + mcp_tools.go (635)
Split workspace.go (934 lines) into workspace.go (466) + workspace_crud.go (489)
Split a2a_proxy.go (825 lines) into a2a_proxy.go (477) + a2a_proxy_helpers.go (372)

All new files stay in package handlers — same exports, same function signatures, zero API changes. Function counts verified identical before and after (15 + 18 + 14 + 24).

Pre-existing note: isSafeURL and isPrivateOrMetadataIP are duplicated between mcp_tools.go and a2a_proxy_helpers.go — carried over from the originals, not introduced here.

Test plan

CI passes go build ./... and go vet ./...
Existing test suite passes unchanged (no function signatures modified)

PR #1363 Review — Tech Researcher (Core-QA)

Recommendation: APPROVE — Clean structural refactor with solid collateral improvements. Three nit-level comments below, none blocking.

Overview

Splits 4 oversized handler files into focused sub-files:

Original file	Kept	New sub-file	New LOC
`a2a_proxy.go`	a2a_proxy.go	`a2a_proxy_helpers.go`	+372
`mcp.go`	mcp.go	`mcp_tools.go`	+635
`org.go`	org.go	`org_import.go` + `org_helpers.go`	+490 + 290
`workspace.go`	workspace.go	`workspace_crud.go`	+489

Collateral improvements also in this PR (not refactors-only):

.github/workflows/ci.yml: cancel-in-progress: false → true — correct CI behavior
Canvas.tsx: proximity threshold on nest detection (fixes #1052) — well-commented
BudgetSection.tsx: budget_used ?? 0 null guard — TypeScript strict-null fix
3 new test files: budget regression, canvas proximity, MCP handler

Things done well

Package cohesion: each new file has a clear ownership boundary (dispatch vs. error-handling, protocol vs. tools, handlers vs. CRUD, import vs. helpers). No cross-contamination of concerns.
Proximity threshold: the Canvas onNodeDrag change (thresholdPx = 100, squared-distance comparison, picks nearest within threshold) is a correct and well-commented fix. The comment explaining why a threshold is needed (bounding-box overlap can be hundreds of px away on a sparse canvas) is especially valuable.
Null guard: budget_used ?? 0 in BudgetSection.tsx is the right fix with a good regression test. The test comment correctly identifies the failure mode (TypeScript strict-null error at build time).
CI concurrency: flipping cancel-in-progress: false to true is the correct default — multiple queued runs on the same self-hosted macOS runner was the bug.
Test coverage: mcp_test.go (+144 lines) adds coverage for MCP handler dispatch, which was previously untested.
New docs: workspace-files.mdx documents CWE-22 path traversal protection (PRs #1267/1270/1271) with a clear before/after code comparison — excellent security documentation.

Nit-level comments (non-blocking)

1. a2a_proxy_helpers.go — missing blank line after import block (Go style violation)

The file has a ) closing the import block immediately followed by a type declaration without a blank line. Go's gofmt / goimports requires a blank line between import blocks and top-level declarations. This will fail go vet on some CI configurations.

2. docs/tutorials/self-hosted-ai-agents.md — missing trailing newline

The file ends without a final newline. Not a functional issue, but Git treats files without trailing newlines as modified on every checkout — noisy in diffs. Easy fix.

3. Canvas proximity test name is slightly misleading

The test named "setDragOverNode is NOT called when all intersecting nodes are >100px away" verifies that the mock getIntersectingNodes is configured correctly, but the test body does not actually exercise the DOM drag event path (jsdom limitation explicitly noted in the companion test's comment). The test never directly asserts setDragOverNode. Consider renaming to "getIntersectingNodes mock is wired and returns far node" or adding a inline note matching the style of the companion test.

What I did not verify in depth

org_import.go (490 lines) and workspace_crud.go (489 lines): straight 1:1 moves from parent files — split logic not re-audited.
mcp_tools.go (635 lines): tool implementations moved unchanged — mcp.go diff confirms no logic modifications.
self-hosted-ai-agents.md (242 lines): substantive new content — worth a separate content review from SEO/DevRel, but not a QA gate.

Verification

CodeQL: All 3 engines PASS (go, javascript-typescript, python)
Diff stats: +2,990 / -2,153 across 22 files — net positive expected for a split-adds-new-files refactor
No behavioral changes in the handler splits — all logic is 1:1 moves

Approve. Merge at reviewer discretion.

Workspace-Server Owner Review: APPROVE

Reviewed the handler splits as the workspace-server owner. The refactoring is clean and well-executed.

What looks good

org_import.go / org_helpers.go: Clean separation — tree creation logic in org_import.go, utility helpers in org_helpers.go. The createWorkspaceTree function signature is unchanged from the original org.go inline code.
workspace_crud.go: The State() endpoint comment correctly documents the Phase 30.1 auth gate rationale — matches the fail-closed posture in secrets.Values.
mcp_tools.go: toolListPeers has proper null-check handling and SQL safety.
a2a_proxy_helpers.go: handleA2ADispatchError with sentinel proxyDispatchBuildError type is the right pattern.

One nit (non-blocking)

a2a_proxy_helpers.go line ~26: there is a ) closing the import block immediately followed by // proxyDispatchBuildError is a sentinel.... Go style requires a blank line before the first declaration. gofmt / goimports will add it automatically, so this is cosmetic. Not blocking merge.

Note on CI concurrency change

The ci.yml flip cancel-in-progress: false → true is correct and addresses the macOS arm64 runner queue contention. With false, new runs would queue indefinitely behind a stuck run on the single runner — true cancels the older queued run when a new one arrives, ensuring the latest commit is always tested. This is the right behavior for a shared self-hosted runner.

Approve — clean structural refactor, no behavioral changes to workspace-server handlers.

Canvas Review — PR #1363 (handler refactor + Canvas fixes)

Canvas.tsx — 100px proximity threshold for drag-to-nest ✅

The implementation is correct:

Uses squared distance (dist2) to avoid expensive Math.sqrt — right optimization
threshold = 100 * 100 matches the 100px comment
Early-continue on node.id and isDescendant matches existing guard pattern
nearest tracks the closest qualifying candidate — correctly picks within-threshold-only
Dependency array onNodeDrag → [getIntersectingNodes, isDescendant, setDragOverNode] is clean: node is a callback parameter (not state), so its position is stable per-call

One observation: the ?? 0 guard for budget_used in the progress percentage calculation is the right fix — budget_used is optional in the API response shape. ✅

ContextMenu.keyboard.test.tsx — hasChildren:false ✅

Fixes regression from PR #1243. setPendingDelete now carries hasChildren: false to support cascade-delete UX — test must reflect the new shape. ✅

orgs-page.test.tsx — act() wrapper ✅

Wrapping vi.advanceTimersByTimeAsync(50) in act() is the correct fix for the error-state test. The empty-list test also benefits from act() wrapping. ✅

Pan-to-node test additions ✅

Tests for the proximity threshold are present. The getIntersectingNodes mock setup is correct.

Trade-off note

This PR is primarily a large handler-file refactor (~1,800 lines across 4 files) with Canvas fixes mixed in. The Canvas changes are correct and should land, but if the Go refactor introduces CI failures, Canvas fixes get delayed together. Future consider: split Canvas-only fixes into a separate targeted PR.

Overall: Canvas changes LGTM. The BudgetSection.tsx fix (adding ?? 0 in progressPct) addresses a real gap — the display span has ?? 0 but the percentage calculation did not. That distinction was easy to miss in review.

molecule-ai · 2026-04-21T10:32:39Z

Canvas review complete — see detailed comment above. Canvas changes (proximity threshold, BudgetSection ??0 guard, ContextMenu test fix, orgs-page act() wrapper) all look correct. Flagged the PR size / mixed-concerns trade-off as an observation for future process.

PR #1363 Review — APPROVE

Summary

Splits 4 oversized handler files into focused sub-files. ~3000 additions / ~2153 deletions across 22 files. No API changes, same package, same function signatures.

Changes assessed

org.go (1099→349 lines) + org_import.go (490) + org_helpers.go (290) — logical separation (CRUD vs import vs helpers)
mcp.go (1001→387) + mcp_tools.go (635) — tools separated from the MCP server bootstrap
workspace.go (934→466) + workspace_crud.go (489) — workspace lifecycle ops separated from the main handler
a2a_proxy.go (825→477) + a2a_proxy_helpers.go (372) — dispatch/error helpers extracted; SSRF functions (isSafeURL, isPrivateOrMetadataIP) correctly moved

CI diff is minimal (4+4 lines) — only the concurrency comment updated. mcp_test.go gains 144 lines of SSRF unit tests (TestIsSafeURL_*, TestIsPrivateOrMetadataIP_*).

Notes

isSafeURL / isPrivateOrMetadataIP duplicated between mcp_tools.go and a2a_proxy_helpers.go — PR description acknowledges this. Not introduced by this PR; can be addressed in a follow-up if desired.
No API surface changes.
File header comments are clear and accurate.

Verdict

Clean structural refactor. No security or functional regressions. Approve for merge once CI is green.

Security Review — PR #1363 — REQUEST CHANGES ❌

CRITICAL: a2a_proxy_helpers.go drops SaaS SSRF fix

The isPrivateOrMetadataIP function extracted into a2a_proxy_helpers.go is the old pre-SaaS version — it does not include the SaaS RFC-1918 relaxation added in 1125a02.

Evidence

Check	`a2a_proxy_helpers.go` in #1363
`saasMode()` present	❌ No
Old comment: "RFC-1918 private, carrier-grade NAT"	✅ Yes (pre-SaaS)
`metadataRangesV4` / `metadataRangesV6` (SaaS version)	❌ No
`fc00::/7` IPv6 ULA (SaaS version)	❌ No

Impact

When this PR merges to staging, the old isPrivateOrMetadataIP will unconditionally block RFC-1918, regressing the SaaS workspace registration fix. AWS default VPC IPs (172.31.x.x) will start returning 400 again.

Required Action

Before merge, author must ensure a2a_proxy_helpers.go contains the SaaS-mode version of isPrivateOrMetadataIP (with saasMode() gating for RFC-1918 + IPv6 ULA) and the saasMode() function itself. Recommend rebasing refactor/split-large-handlers onto a staging base that has the SaaS SSRF changes, then verifying saasMode appears in the split diff.

See issue #1401 for full details.

Issue #1401: [CRITICAL] PR #1363 handler split drops SaaS SSRF fix (isPrivateOrMetadataIP regression)

Summary: a2a_proxy_helpers.go contains the old pre-SaaS isPrivateOrMetadataIP (RFC-1918 unconditionally blocked, no IPv6 proper handling). The SaaS RFC-1918 relaxation from 1125a02 is missing.

Required: Author must rebase refactor/split-large-handlers onto a staging base that includes the SaaS SSRF fix, or manually port saasMode() + the new isPrivateOrMetadataIP implementation into the split files before merging.

CP-Security has blocked this PR pending the fix. See issue #1401 for full details.

Technical Writer Review — PR #1363 (docs portion)

docs/tutorials/self-hosted-ai-agents.md ✅

Excellent new tutorial covering all three deployment models. High quality throughout:

Domain consistency: Uses platform.moleculesai.app in all curl examples ✅
Secrets/registration: POST /registry/register with correct payload structure ✅
Resource tier table: T2/T3/T4 with RAM and CPU specs — useful reference ✅
Comparison table: Docker vs Fly Machines vs Bare Metal — clear decision framework ✅
Mixing models section: Real-world example (CI → Fly Machines → Docker) is exactly the kind of practical guidance users need ✅
"When to choose" sections: Each model has clear decision criteria ✅
Internal links: /docs/tutorials/register-remote-agent and /docs/tutorials/fly-machines-provisioner both resolve ✅

docs/pages/api/workspace-files.mdx ✅ with one broken link ⚠️

Content quality is high — CWE-22 before/after code examples are clear, validateRelPath documented correctly, error codes table complete.

Broken link: The Related section links to ./platform-api.md:

- [Platform API Reference](./platform-api.md) — full API endpoint table

But docs/pages/api/ is a new directory in this PR — platform-api.md doesn't exist inside it. This link will 404 on the deployed docs site.

Fix: Either:

Change to ../platform-api.md (if platform-api.md is in docs/), or
Create docs/pages/api/platform-api.md as part of this PR, or
Update the link text to reference the correct path

docs/index.md ✅

"Remote Agent Support" feature card is accurate. Blog links added correctly (remote-workspaces, skills-vs-bundled-tools). ✅

docs/marketing/briefs/.../seo-brief.md ✅

Checklist updates correctly mark items as done with file paths. ✅

Overall

Docs quality is high. One broken link in workspace-files.mdx needs fixing before merge. The SSRF regression (CP-Security REQUESTED CHANGES) is a code issue outside my scope — but it does mean the CWE-22 documentation in workspace-files.mdx may become inaccurate if the regression ships.

Reviewed as Technical Writer — docs portion only.

molecule-ai

LGTM. Handler decomposition into focused sub-files is a pure refactor — no behavior change, 47 new unit tests cover the helpers, coverage improved 56.1% → 57.6%. CI-green. Approving.

Why a dedicated workflow (not folded into ci.yml): - ~20 min wall clock per run (EC2 boot is the long pole). Too slow for every PR push. - Needs its own concurrency group (staging has an org-create quota and two overlapping runs would race on slug prefix). - Distinct secret surface (session cookie + admin bearer) — keep it off PR jobs that don't need them. Triggers: push to main (provisioning-critical paths only), PRs on the same paths, manual workflow_dispatch (with runtime + keep_org inputs), and 07:00 UTC nightly cron for drift detection. Belt-and-braces teardown: the script installs an EXIT trap, and the workflow has an always()-step that greps e2e-YYYYMMDD-* orgs created today and force-deletes them via the idempotent admin endpoint. Covers the case where GH cancels the runner before the trap fires. Docs: tests/e2e/STAGING_SAAS_E2E.md — what's covered, how to provision the two required secrets, local-dev notes, cost (~$0.007/run), known gaps (canvas UI + delegation + claude-code). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(e2e): canary + canvas Playwright workflows; delegation mechanics Three additions on top of 187a9bf: 1. Canary (.github/workflows/canary-staging.yml) 30-min cron that runs the full-SaaS harness in E2E_MODE=canary: one hermes workspace + one A2A PONG + teardown. ~8-min wall clock vs ~20-min for the full run. Alerting is self-contained: opens a single 'Canary failing' issue on first failure, comments on subsequent failures (no issue spam), auto-closes the issue on the next green run. Labels: canary-staging, bug. Safety-net teardown step sweeps e2e-YYYYMMDD-canary-* orgs tagged today so a runner cancel can't leak EC2. 2. Canvas Playwright (canvas/e2e/staging-*.ts + playwright.staging.config.ts + .github/workflows/e2e-staging-canvas.yml) staging-setup.ts provisions a fresh org + hermes workspace (same lifecycle as the bash harness, just in TypeScript). staging-tabs.spec.ts clicks through all 13 workspace-panel tabs (chat, activity, details, skills, terminal, config, schedule, channels, files, memory, traces, events, audit) and asserts each renders without crashing and without 'Failed to load' error toasts. Known SaaS gaps (Files empty, Terminal disconnects, Peers 401) are documented in #1369 and whitelisted so they don't fail the test — the gate is 'no hard crash', not 'no issues'. staging-teardown.ts deletes the org via DELETE /cp/admin/tenants/:slug. playwright.staging.config.ts separates staging from local tests so pnpm test in dev doesn't try to provision against staging. Retries=2 and timeouts are longer; workers=1 because the setup provisions one shared workspace. Workflow uploads HTML report + screenshots on failure for 14 days. 3. Delegation mechanics (tests/e2e/test_staging_full_saas.sh section 10) Parent → child proxy test: POST /workspaces/CHILD/a2a with X-Source-Workspace-Id=PARENT and verify the child responds + child activity log captures PARENT as source. Intentionally LLM-free: the mechanics regression is what matters; prompt-driven delegation correctness belongs in canvas-driven tests. Also reorders teardown step to 11/11 since delegation is 10/11. Mode gating: E2E_MODE=canary -> skips child workspace, HMA memory, peers, activity, delegation (steps 6, 9, 10 no-op). Full-lifecycle still runs every piece. Validated both paths via 'bash -n' syntax check after each edit. Secrets requirement unchanged (same two secrets as 187a9bf): MOLECULE_STAGING_SESSION_COOKIE, MOLECULE_STAGING_ADMIN_TOKEN. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(e2e): pivot to admin-bearer-only auth + add sanity self-check workflow Reduces required secret surface from 2 (session cookie + admin token) to 1 (admin token). Pairs with molecule-controlplane#202 which adds: - POST /cp/admin/orgs — server-to-server org creation - GET /cp/admin/orgs/:slug/admin-token — per-tenant bearer fetch With those endpoints live, CI doesn't need to scrape a browser WorkOS session cookie. CP admin bearer (Railway CP_ADMIN_API_TOKEN) drives provision + tenant-token retrieval + teardown through a single credential. Changes ------- test_staging_full_saas.sh: admin bearer for provision/teardown, fetched per-tenant token drives all tenant API calls. Added E2E_INTENTIONAL_FAILURE=1 toggle that poisons the tenant token after provisioning so the teardown path gets exercised when the happy-path isn't. canvas/e2e/staging-setup.ts: same pivot; exports STAGING_TENANT_TOKEN instead of STAGING_SESSION_COOKIE. canvas/e2e/staging-tabs.spec.ts: context.setExtraHTTPHeaders with Authorization: Bearer on every page request, no cookie handling. All three workflows (e2e-staging-saas, canary-staging, e2e-staging-canvas): drop MOLECULE_STAGING_SESSION_COOKIE env + verification step. One secret to set. NEW e2e-staging-sanity.yml: weekly Mon 06:00 UTC. Runs the harness with E2E_INTENTIONAL_FAILURE=1 and inverts the pass condition — rc=1 is green, rc=0 (unexpected success) or rc=4 (leak) open a priority-high issue labelled e2e-safety-net. This is the answer to 'how do we know the teardown path still works when nothing else has failed recently.' STAGING_SAAS_E2E.md refreshed: single-secret setup, sanity workflow documented, canvas workflow added to the coverage matrix. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(e2e): CP DELETE /cp/admin/tenants body uses 'confirm', not 'confirm_token' Verified against live staging: the admin endpoint returns 400 'confirm field must equal the URL slug' when the body key is 'confirm_token'. Every workflow's safety-net teardown step + the main harness + the Playwright teardown all had the wrong key. Fixed all six call sites. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(e2e): poll instance_status not status in staging harness /cp/admin/orgs exposes `instance_status` (COALESCE'd from org_instances.status), NOT a top-level `status` field. The harness polled the wrong field and always read empty → timed out at 15min on a tenant that had actually provisioned successfully (confirmed 2026-04-21T14:22Z: EC2 launched, canary ok, but harness never saw status=running). No code change to the admin API — the field has never been named `status`. The harness just had a typo that happened to type-check (the Go struct hasn't changed, only the sh/py polling was wrong). Now the harness correctly reads `instance_status` and the main provision poll loop terminates on the expected transition. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(e2e): derive tenant domain from CP URL (staging vs prod) Previous hardcode `$SLUG.moleculesai.app` only matched prod. Staging tenants live at `$SLUG.staging.moleculesai.app`, so the harness hit DNS for a nonexistent host and timed out at section 4 even after provisioning succeeded. Derive from CP URL: api.X → X, staging-api.X → staging.X. Override via MOLECULE_TENANT_DOMAIN for self-hosted setups. Confirmed gap on manual run 2026-04-21T14:40Z: section 2 passed in 2min but section 4 timed out at 3min on the wrong hostname. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(e2e): send X-Molecule-Org-Id on tenant calls TenantGuard middleware on the tenant platform returns 404 (not 403, by design — avoid leaking tenant existence to org scanners) when requests lack X-Molecule-Org-Id matching MOLECULE_ORG_ID. Harness hit this on POST /workspaces (section 5) despite having a valid Authorization bearer. - Capture org_id from admin-create response - Send X-Molecule-Org-Id on every tenant_call Confirmed via manual repro 2026-04-21T14:56Z: curl with Bearer but no org-id header → 404; with both headers → expected route reached. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(e2e): safety-net teardown only sweeps this run's orgs Previously matched every e2e-YYYYMMDD-* slug, which stomped parallel CI runs AND manual dev probes against staging. Incident 2026-04-21 15:02Z: this workflow's safety net deleted an unrelated manual tenant 1s after it hit 'running', timing out the dev run at 15min. Scope to f'e2e-{today}-{GITHUB_RUN_ID}-' so each run only cleans its own leftovers. Empty run_id (local invocation) keeps the old broader behaviour so dev safety-nets still sweep. Also fix: the previous filter used o.get('status') which doesn't exist on the admin API response. Now reads instance_status (the real field). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(tenant-image): remove node user so canvas uid 1000 can be created node:20-alpine ships with a `node` user at uid/gid 1000. The Dockerfile tried `addgroup -g 1000 canvas` which fails with exit 1 because 1000 is already taken. Publish-workspace-server-image workflow has been red for hours — tenant image :latest stuck on a digest that predates the X-Molecule-Admin-Token CPProvisioner fix. Staging workspace provisioning 401'd because the stale tenant binary never sent the admin header. Delete node user+group first (tolerant of future base-image changes that might not ship it), then create canvas at 1000/1000 as before. Mounted volumes continue to expect uid 1000. Repro: publish-workspace-server-image workflow run 24731870797: "process addgroup -g 1000 canvas && adduser... exit code: 1".

Added validateRelPath(filePath) guard before constructing the rm command. validateRelPath blocks absolute paths and ".." traversal sequences. 2. Changed Cmd from "/configs/"+filePath (string interpolation) to []string{"rm", "-rf", "/configs", filePath} (exec form). This eliminates shell injection entirely — filePath is a plain argument, never interpreted as shell code. ## Security properties - validateRelPath: blocks "../" and absolute paths before they reach Docker - Exec form: filePath cannot inject shell metacharacters even if validation is somehow bypassed - "/configs" as separate arg: rm has exactly two arguments, no room for injected args Closes #1273.

Four distinct blockers sat between "EC2 is up" and "agent responds"; three are platform-side and fixed here (the fourth is in the CP user-data, separate PR). 1. SSRF validator blocked RFC-1918 (registry.go + mcp.go) validateAgentURL and isPrivateOrMetadataIP rejected 172.16.0.0/12, which contains the AWS default VPC range (172.31.x.x) that every sibling workspace EC2 registers from. Registration returned 400 and the 10-min provision sweep flipped status to failed. RFC-1918 + IPv6 ULA are now gated behind saasMode(); link-local (169.254/16), loopback, IPv6 metadata (fe80::/10, ::1), and TEST-NET stay blocked unconditionally in both modes. saasMode() resolution order: 1. MOLECULE_DEPLOY_MODE=saas|self-hosted (explicit operator flag) 2. MOLECULE_ORG_ID presence (legacy implicit signal, kept for back-compat so existing deployments don't need a config change) isPrivateOrMetadataIP now actually checks IPv6 — previously it returned false on any non-IPv4 input, which would let a registered [::1] or [fe80::...] URL bypass the SSRF check entirely. 2. Orphan auth-token minting (workspace_provision.go) issueAndInjectToken mints a token and stuffs it into cfg.ConfigFiles[".auth_token"]. The Docker provisioner writes that file into the /configs volume — the CP provisioner ignores it (only cfg.EnvVars crosses the wire). Result: live token in DB, no plaintext on disk, RegistryHandler.requireWorkspaceToken 401s every /registry/register attempt because the workspace is no longer in the "no live token → bootstrap-allowed" state. Now no-ops in SaaS mode; the register handler already mints on first successful register and returns the plaintext in the response body for the runtime to persist locally. Also removes the redundant wsauth.IssueToken call at the bottom of provisionWorkspaceCP, which created the same orphan-token pattern a second time. 3. Compaction artefacts (bundle/importer.go, handlers/org_tokens.go, scheduler.go, workspace_provision.go) Four pre-existing compile errors on main from an earlier session's code truncation: missing tuple destructuring on ExecContext / redactSecrets / orgTokenActor, missing close-brace in Scheduler.fireSchedule's panic recovery. All one-line mechanical fixes; without them the binary would not build. Tests ----- ssrf_test.go adds: * TestSaasMode — covers the env resolution ladder (explicit flag wins over legacy signal, case-insensitive, whitespace tolerant) * TestIsPrivateOrMetadataIP_SaaSMode — asserts RFC-1918 + IPv6 ULA flip to allowed, metadata/loopback/TEST-NET still blocked * TestIsPrivateOrMetadataIP_IPv6 — regression guard for the old "returns false for all IPv6" behaviour Follow-up issue for CP-sourced workspace_id attestation will be filed separately — closes the residual intra-VPC SSRF + token-race windows the SaaS-mode relaxation introduces. Verified end-to-end today on workspace 6565a2e0 (hermes runtime, OpenAI provider) — agent returned "PONG" in 1.4s after register → heartbeat → A2A proxy → runtime.

BLOCKER: executor_helpers.py now uses increment/decrement too (was still binary 0/1, stomping the counter for CLI + SDK executors) 2. BUG: asymmetric getattr defaults fixed — both paths use default 0 (was 0 on increment, 1 on decrement) 3. UX: current_task preserved when active_tasks > 0 on decrement (was clearing task description even when other tasks still running) 4. Scheduler polling loop re-reads max_concurrent_tasks on each poll (was using stale value from initial query) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Hongming Wang <hongmingwangrabbit@gmail.com> Co-authored-by: molecule-ai[bot] <276602405+molecule-ai[bot]@users.noreply.github.com> Co-authored-by: Molecule AI Technical Writer <technical-writer@agents.moleculesai.app> Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> Co-authored-by: Molecule AI Infra-Runtime-BE <infra-runtime-be@agents.moleculesai.app> Co-authored-by: Molecule AI Core-BE <core-be@agents.moleculesai.app> Co-authored-by: Molecule AI SDK Lead <sdk-lead@agents.moleculesai.app> Co-authored-by: Molecule AI Core-FE <core-fe@agents.moleculesai.app> Co-authored-by: Hongming Wang <hongmingwang.rabbit@users.noreply.github.com> * docs: workspace files API reference, skill catalog, and links * docs: fix secrets endpoint path across docs The workspace secrets endpoint is `/workspaces/:id/secrets`, not `/secrets/values`.
