Fixes #915

Summary

  • introduce the harness-neutral remoteControlDaemon session marker and symmetric --daemon CLI vocabulary for Claude and Codex
  • reserve remoteControl for Claude's per-session /rc capability, while preserving legacy Claude and Codex daemon encodings on read
  • dual-write legacy fields from new session writers so rollback remains safe, and retain deprecated CLI, environment, and Settings pseudo-profile spellings
  • update daemon detection across Settings, session APIs, supervision, hibernation, Spot handling, and WhatsApp task binding
  • refresh documentation, generated module output, native fixtures, and golden snapshots

Compatibility

New daemon sessions write both the canonical marker and the prior harness-specific fields. Existing registries continue to work, including Claude remoteControl=true + remoteControlServer=true, Codex remoteControl=true, --remote-control server, and the prior Settings/environment values.

Validation

  • nix build -L --keep-going .#ci-native
  • python3 tests/test-codex-pairing.py
  • python3 tests/test-profile-panel.py
  • python3 tests/test-session-capacity.py
  • python3 tests/test-sessions-api.py
  • python3 tests/test_agentbox.py
  • git diff --check origin/master...HEAD

The x86_64 VM lanes are left to GitHub CI on this aarch64 host.

📝 Walkthrough

The change separates interactive Remote Control from persistent daemon mode for Claude and Codex. It adds a canonical daemon session field and --daemon option, preserves legacy settings and flags, and updates session creation, runtime selection, settings flows, metadata, and documentation.

Changes: Claude and Codex daemon mode

Layer / File(s) Summary
Daemon configuration and session shape
README.md, bin/agentbox, modules/agent-box.nix, modules/agent-box.nix.in, modules/src/default-agents.md, tests/spec.nix, tests/native/expected/etc/agent-box/seed/*, tests/test_agentbox.py, tests/golden/*/etc/agent-box-guides/*
Configuration and session seeds add remoteControlDaemon. Validation limits the option to Claude and Codex. Documentation distinguishes interactive Remote Control from daemon mode and describes legacy aliases.
Daemon session creation
modules/agent-box.nix, modules/src/session-cli.sh, tests/golden/vm/payloads/agent-box-session/bin/agent-box-session, tests/sessions.nix
The CLI adds --daemon and retains --remote-control server as a deprecated alias. It normalizes legacy Codex daemon selection, validates incompatible options, and writes the daemon marker while keeping Claude’s legacy field.
Daemon recognition and runtime handling
modules/agent-box.nix, modules/src/lib/session-hibernation.py, modules/src/spot-monitor.sh, modules/src/supervisor.sh, tests/golden/vm/payloads/*
Runtime components recognize the canonical marker and legacy encodings. Daemon status controls harness launch, hibernation exclusion, and Spot notification handling.
Settings, pairing, and session metadata
modules/agent-box.nix, modules/src/settings-daemon.py, tests/golden/web/payloads/agent-box-settings/bin/agent-box-settings, tests/test-codex-pairing.py, tests/test-profile-panel.py, tests/test-sessions-api.py
Settings and pairing flows create and classify daemon sessions. Session metadata exposes daemon status, and picker and row labels use daemon terminology. Claude daemon prompt and WhatsApp restrictions remain in place.

Merge Risk: 🔴 Critical · up to c5077

After this change, Claude sessions fail to start: the supervisor stops on an unset variable before creating the Claude pane. Codex daemon sessions recorded only with the new daemon flag also start as daemons but are tracked and restarted as ordinary terminal sessions. This would break a core workflow if merged and should be fixed first.

Explanation

The changed source files implement daemon classification and compatibility handling. The documentation, tests, fixtures, golden snapshots, and generated output support the same issue #915 behavior. No unrelated change is established by the reviewed summary.

Full details: Docstring Coverage

Explanation

Docstring coverage is 48.57% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 35 functions across 9 files. (21 skipped: 21 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Full details: Linked Issues check

Explanation

Issue #915 coding objectives are implemented in the reviewed changes. The code adds remoteControlDaemon, preserves legacy Claude and Codex encodings, adds --daemon compatibility handling, updates Settings, APIs, supervision, hibernation, Spot, and WhatsApp logic, and adds documentation, regression tests, fixtures, and generated artifacts. The reported native validation covers the listed native tests. The PR description states that the x86_64 VM lanes remain for GitHub CI, so completion of the relevant VM and CI automated checks is not established.

Resolution

Provide evidence that the relevant x86_64 VM lanes and CI checks pass, then reassess issue #915 compliance.

- Around line 1089-1092: Update the remote-control checks in start_session to
use the derived rcdaemon value instead of unassigned rcserver, and include
rcdaemon in Claude name derivation and Codex daemon-session routing, target
selection, exit handling, and native-session recording. Keep TUI-only behavior
gated on rc so daemon sessions are not treated as TUI sessions.
