Adds the python side of the delegation helpers and switches lib.sh over to it.
daemon.py port of start_watchdog. Same monitor path, same pgrep pattern, so
a daemon started by either implementation is found by the other;
same stderr wording and exit 1 when reconcile.sh is missing; same
"print the PID" contract, multiple pgrep matches included, since
the shell echoed them all and trimming would be a silent change.
start_new_session detaches it, and SIGHUP is ignored across the
exec so it outlives its parent exactly as nohup did.
cli.py thin router. submit/publish forward to the existing main() of the
module that already owned the behaviour, so exit codes, stdout
shape and side effects cannot drift between the shell path and
the script path. Only ensure-daemon carries logic of its own.
service.py DelegationService facade, with an optional persistent connection
for the phase 2a engine. CLI and shell always use one-shot.
lib.sh keeps the three legacy bodies verbatim as _*_legacy behind
MAM_DELEGATION_PY=0, which is the instant rollback switch. PYTHONPATH is passed
explicitly so `-m` resolves lib_py from the tree this lib.sh belongs to, which
is what makes a frozen loop run frozen delegation code. start_watchdog survives
as an alias for ensure_subscriber_daemon.
The wrapper and run_loop.sh are untouched; reconcile.sh gains only the
ensure_env_loaded line from the previous commit.
Verified: C-01..C-09 pass against both the legacy and the python bodies, the
daemon dedups and survives its parent, the cli reproduces the legacy failure
line exactly, and publish failure semantics (status synced, seq consumed,
audit records published=false) are identical through the shim and the cli.
tier1+tier2 109 passed; bash -n clean on all six shell files.

Claude-Session: https://claude.ai/code/session_01UrDNJkHmm18uu7n7JwV5Qd
- Implement CodexAdapter in lib_py/agents/adapters/codex.py with safe flags and TUI readiness
- Extend create_session, resume_session, stop_session, and reconcile for codex CLI
- Support codex agent delegation and loop integration across all multi-agent skills
- Add unit, component, and contract test suites for codex integration
- Verify all 462 tests passing cleanly
- Prevent injecting 'env HERDR_WORKSPACE_ID=...' into final_cmd when caller passed no environment variables
- Avoid argument parse errors in real agent binaries (e.g. grok, agy) when reusing an idle pane in new-session
- Replace 'nohup ... server & disown' with portable Python 'Popen(..., start_new_session=True)' in lib.sh shim generator
- Isolate headless herdr server in its own SID/PGID to protect against parent process-group signal broadcast (SIGTERM/SIGINT)
- Add regression test test_h26_daemon_spawn_uses_process_group_detachment to verify child PGID detachment (Closes#3 Item 1)
- Bump MAM_VERSION to 4.0.0 in lib.sh
- Bump all 8 skill frontmatter versions to 4.0.0 in 3-way lockstep
- Update VERSIONS.md with v4.0.0 changelog, migration guide (B-1..B-5), and skill matrix
- Archive multi-agent version upgrade consensus and peer review reports (439 passed, 0 failures)
- Define immutable MAM_VERSION="3.1.0" runtime constant in lib.sh
- Bump YAML frontmatter version to 3.1.0 across all 8 skill packages
- Document v3.1.0 changelog, 2-tier TUI readiness architecture, and migration guide in VERSIONS.md
- Document new tuning knobs (MAM_KILL_ON_READY_TIMEOUT, MAM_DIALOG_TAIL_LINES, MAM_READY_EMPTY_GIVEUP) in .mam.env.example
- Add 3-way lockstep and immutability test suite in tests/test_version_consistency.py
- Separate TUI dialog detection into blocking gate layer (_MAM_MODAL_TOKENS) and recovery layer (_MAM_HINT_TOKENS) to eliminate idle dialog starvation
- Add modal_tokens contract across agent adapters (claude, cline) with dynamic scope facts resolution in send_keys_safe
- Implement fail-closed resolution for ambiguous same-kind panes (R-1) and enforce WORKSPACE_ROOT export (R-2)
- Preserve session on TUI readiness timeout when PID is alive for diagnostics
- Add comprehensive test suite in tests/test_c1_tui_readiness.py and adapter contract assertions in test_a4
- Accept agent_not_ready from herdr agent start to allow startup dialog handling without premature rollback, while preserving fail-closed behavior on dead process timeouts.
- Match Claude fullscreen renderer upsell modal via 'Yes, try it' and dismiss with Escape to avoid dropping permission flags or deadlocking on idle /tui tips.
- Add behavioral test suite in test_b19_headless_reconcile_fixes.py and cross-agent review reports.
- Change N=1->2 split policy from down to right to establish 2 full-height columns
- Share single decision table across GUI and headless modes
- Add _full_height_pane guard to prevent half-height column splits
- Quadruple-wire default max_columns=2 and max_rows=2 across layout.py, lib.sh, and .mam.env.example
- Update unit and integration tests to enforce deterministic 2x2 grid trajectory
- In stop_session.sh and update_yaml_resumed.sh: standardize explicit --agent option and use resolve_agent_type_from_registry to read agent type from YAML/DB state rather than brittle suffix-only regex inference.
- Update multi-agent-mux-stop/SKILL.md, multi-agent-mux-resume/SKILL.md, multi-agent-mux-create/SKILL.md, and deploy/INSTALL.md to standardize passing --agent explicitly.
- Fix J-1 in layout.py: refactor _env_int(*names, default=None) to take an explicit default parameter, eliminating the falsy-zero trap so MAM_MIN_PANE_COLS=0 is respected.
- Add regression and contract tests: test_j1_env_zero_min_cols_matches_flag_zero, test_j1_env_zero_min_rows_matches_flag_zero, test_comp_stop_agent_fallback_*, test_comp_docs_stop_examples_pass_agent.

- Remove dead agent_identities read path and PyYAML import from workspace_uuid.py
- Defer eager PyYAML import in verify_session.py to lazy YAML fallback branch
- Simplify UUID resolution to 2-tier model (tier-1 own row ID -> tier-2 adapter scan)
- Clean up unused Drift D and ghost cache clearing in reconcile.sh and stop_session.sh

- Update IMPROVEMENTS.md, VERSIONS.md, and SKILL.md files
- Option B / C-3b: Deprecate isolation.root and remove its 4 legacy consumers in lib.sh, workspace_uuid.py, verify_session.py, and stop_session.sh.
