fix: reconcile documentation guarantees and enforcement (OM-15)

[chriswritescode-dev]

Summary

Addresses the 22 findings in the October 2 documentation drift audit against main at 6c878ae79a8a7a47f2c42a8df74c05c49dff4df2.

• Enforce preconfigured-admin signup suppression in the shared Better Auth user-creation hook, while preserving internal admin provisioning and existing-account sign-in.
• Preserve complete version tokens and fail closed on version-probe errors through one shell parser shared by Docker and development setup.
• Move legacy quarantine configuration restoration into the configuration-file owner, locking the whole read-modify-write operation by configuration directory and retaining backups on failure.
• Correct HTTPS cookie defaults, Docker reset/recreation and backup procedures, Compose service keys and environment forwarding, CLI destination selection and forced replacement, schedule isolation/retention, sandbox protections, notifications, shared pins, and contributor/API references.

Validation

• 296 distinct focused tests passed: 267 backend and 29 CLI tests.
• Native Bun/Better Auth check passed: HTTP signup rejected with 403, configured admin provisioned, sign-in returned 200.
• Backend typecheck passed.
• Repository lint passed with 40 existing warnings in unchanged backend/src/routes/repos.test.ts; final parser-test edits also passed focused lint.
• Shell syntax checks passed for all three changed scripts.
• Diff whitespace checks passed; 19 relative documentation link targets and the new sandbox anchor were checked.
• Replacement contributor test example executed successfully.

Limitations and follow-ups

• MkDocs was unavailable; no documentation build, full-suite coverage run, or deployment test was performed.
• A broader companion test run reported four SSH-route POST /test-ssh failures outside the changed modules; the baseline was not independently reproduced here.
• Successful-session push delivery from execution events remains an unconfirmed runtime follow-up outside the 22 findings.

project.md / OM-15

The user confirmed preserving workspace-scoped effective-config inspection and the fixed-white HTML preview canvas. Canonical documentation deltas are staged, not promoted:

• Proposed/OM-15/Agent Sandboxing.md
• Proposed/OM-15/Decisions.md
• Proposed/OM-15/Project Overview.md

After merge, promote these deltas and refresh the canonical overview and companion diagram. OM-15 remains in progress until promotion is complete.

Summary by CodeRabbit

• New Features

  • Scheduled-run completion and error notifications now open the run report instead of its session.
  • When an administrator account is preconfigured, new registrations—including OAuth sign-ups—are blocked. The configured administrator can still be provisioned at startup.

• Bug Fixes

  • Legacy OpenCode configuration backups are restored when available, while invalid configuration files are left unchanged.
  • The ocm command now avoids selecting a previously saved repository when run inside a Git repository without a matching Manager project.

• Documentation

  • Updated setup, configuration, security, Docker, and scheduled-run guidance, including defaults and limitations.

📝 Walkthrough

Walkthrough

The pull request changes authentication registration checks, legacy OpenCode config restoration, and OpenCode version parsing. It also updates configuration, development, product-feature, CLI, and operational documentation.

Changes

Admin signup

Layer / File(s)	Summary
Admin registration check backend/src/auth/index.ts, backend/src/routes/auth.ts, backend/test/auth/index.test.ts, docs/configuration/authentication.md	The auth module rejects disallowed user creation when both admin credentials are configured. Routes use the shared configuration check. Tests and documentation cover the registration behavior.

Legacy OpenCode config restoration

Layer / File(s)	Summary
Backup restoration and quarantine integration backend/src/services/opencode-config-file.ts, backend/src/services/opencode-plugin-quarantine.ts, backend/test/services/opencode-config-file.test.ts, backend/test/services/opencode-plugin-quarantine.test.ts	A shared service restores enforcement sections from legacy backups under a file lock. Quarantine restoration calls that service. Tests cover successful restoration, invalid config roots, backup retention, and serialized updates.

OpenCode version parsing

Layer / File(s)	Summary
Shared version-output parsing scripts/lib/opencode-release.sh, scripts/docker-entrypoint.sh, scripts/setup-dev.sh, backend/test/scripts/docker-entrypoint.test.ts, backend/test/shared/opencode-contract.test.ts	A shared helper parses version output. The entrypoint and development setup scripts use it. Tests cover valid and malformed output, binary reconciliation, and failed version probes.

Documentation updates

Layer / File(s)	Summary
Configuration and development guidance .env.example, AGENTS.md, CONTRIBUTING.md, docs/configuration/*, docs/development/setup.md, docs/getting-started/first-run.md, docs/troubleshooting.md	Documentation updates describe variable defaults, Docker Compose behavior, project commands, test examples, password resets, and database recovery.
Product behavior documentation docs/features/assistant-internal-api.md, docs/features/notifications.md, docs/features/sandboxing.md, docs/features/schedules.md, docs/features/session-pins.md	Feature documentation clarifies API responses, notification destinations, sandbox boundaries, scheduled-run behavior, and pin scope.
CLI behavior documentation docs/ocm-cli.md, ocm-cli/README.md	CLI documentation describes project-ID repo matching, saved-repo fallback, move behavior, and repo creation conditions.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to dcb50

This change is mostly documentation plus small guarded runtime changes. One doc line about --create overstates that it always creates a new repo; fix it before or shortly after merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to dcb50

The changes tighten registration controls and improve configuration recovery. No introduced security weakness was established, but production authentication behavior and recovery with external configuration writers remain partially validated.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The reviewed authority boundaries are public account creation into the backend account database, recovery of local OpenCode configuration affecting plugins and execution-related sections, and selection of a local OpenCode executable. The available evidence does not establish tenant-wide isolation or coordination across multiple backend processes.

Trust Boundaries and Controls

• observed — The new creation control distinguishes public requests from internal provisioning using request-context presence and configured-email equality, not a newly authenticated internal principal. Route forwarding and focused handler tests support the intended separation, but the supplied production-runtime proof gap is not fully closed.
• observed — Docker probes executables as the node user and discards failed probe output. Persisted unversioned binaries are removed, while development setup rejects empty or unsupported versions. Docker's top-level unknown-version branch still proceeds toward backend startup, so these changes do not establish a universal fail-closed startup guarantee.

Resilience and Maintainability Implications

• observed — Recovery validation rejects non-object configuration without overwriting it, retains the backup on that failure, and propagates restoration errors into the existing startup refusal path. This supports failure containment rather than launching with a known failed restoration.
