A non-numeric MAM_READY_EMPTY_GIVEUP, SKS_EMPTY_GIVEUP, SKS_IDLE_RETRIES,
SKS_IDLE_RETRY_BACKOFF_S, MAM_LOCK_STEAL_RETRIES, MAM_DIFF_MAX_BYTES,
MAM_DIFF_MAX_LINES or RECONCILE_POLL_INTERVAL was a `[` error or a sleep
error at the point of use (PR #43 review claude R3). They now go through
mam_int_knob: decimal, a warning and the default for a bad value. Minimums
are in test_issue26_ints.py INT_KNOBS: 1 for the give-up counts (0 acts as
1), the diff caps (0 truncates every diff) and the poll interval (0 is a
busy loop); 0 for the retry counts (one attempt) and the retry backoff.
SKS_QUIESCENT_INTERVAL stays raw: its default is 0.5 s and sleep's
fraction is its meaning; NOT_ARITHMETIC says so.
loop_lock.sh and diff_collect.sh also run without lib.sh (the Python runner
and the tests source them alone), so mam_int / mam_int_knob move verbatim
to lib_int.sh, which lib.sh sources and those two source when the function
is missing. remove.sh's no-manifest fallback list names the new file
(install copies every file under .agents/skills). test_issue21_loop_b l15,
which builds a control root holding only diff_collect.sh, copies it too.
Tests: the table guard now reads every shell file; scripts sourced alone
read their knobs as decimal; _pane_quiescent with SKS_EMPTY_GIVEUP=abc
gives up with a warning and no `[` error (14 of the new cases fail at
0051fd6).

A session row now records the control plane it belongs to, and the pane
gets it explicitly instead of relying on env inheritance.
- lib_py/control_plane.py (+ thin lib.sh wrappers mam_control_plane_json /
mam_control_plane_prefix): the binding is WORKSPACE_ROOT,
AGENT_SESSIONS_YAML, MAM_JOBS_DIR, DELEGATE_JOB_LOGS_DIR as absolute paths.
- create: the binding is always persisted on the row (`control_plane`) and
forwarded to the pane only when it differs from what --workspace alone
implies, as leading K=V tokens that lib.sh's new-session already turns into
--env (fresh pane) or `env K=V` (reused idle pane). pane.cmd_full and
start_command stay unprefixed. A binding with whitespace that would have to
be forwarded is refused with exit 2 (lib.sh splits the flags unquoted); the
~/.local/bin wrapper path records the binding but warns it is not forwarded.
- resume: the row's binding wins over the caller's env (a difference is
reported on stderr) and is forwarded again; a legacy row without one uses
the caller's binding and update_yaml_resumed.sh records it.
- stop: registry order MAM_JOBS_DIR > the row's mam_jobs_dir >
$WORKSPACE_ROOT/.mam/jobs > .mam/jobs, exported for delegate_publish_event.
- status: both get_job_status copies look in MAM_JOBS_DIR, the row's
registry and the matching audit logs before the old candidates.
- reconcile: MAM_JOBS_DIR wins in the subscribe heredoc and is passed in.
Tests T3-0..T3-8 (mock herdr: forwarding is verified at the herdr-call level
only; real pane env propagation is left to item 7). T3-7 is a static guard.

Review round 3 (reviewer-grok-01, NOT PASS N1; non-blocking B1):
- reconcile.sh (N1): the python subscriber installs its SIGTERM/SIGINT
handlers before connect/loop_start. A signal during the broker handshake,
the CONNACK wait, or right after the paho thread logs "subscribed to" now
takes the clean path (the signal line, loop_stop/disconnect, rc 0) instead
of Python's default action; the CONNACK wait ends on it, and a signalled
subscriber never falls back to polling (rc 3).
- reconcile.sh (B1): `_sub_stop` reads `$!` with nounset off. On bash 3.2
`${!:-}` and `${!+x}` are both unbound before the first `&`, so the trap
died with rc 1 instead of 143.
- tests: SIGTERM during a CONNACK wait against a silent local listener (no
broker needed), and the verbatim `_sub_stop` run without and with a
child; both fail on 8f9745b.
- docs: monitor SKILL.md and VERSIONS.md state the handler order; test
count 16.

Review round 2 (planner-reviewer-codex-01, NOT PASS P2):
- conftest `_is_subscriber_daemon_argv`: `ps -o args=` joins argv unquoted,
so the script path is taken from the shell word up to the first
`/reconcile.sh --subscribe` instead of as one whitespace token. A sandbox
or --basetemp path with a space no longer hides its daemon from the
fixture reaper and the session leak guard. A candidate with whitespace
counts only when it names an existing file, so a bash wrapper under the
root whose later argv carries the words is still excluded.
- tests: a whitespace-path selector regression and an owned live-process
cleanup check (both fail on c096cb4); the R-2 test also pins the bash
wrapper exclusion.
- docs: the polling fallback's signal handling is stated precisely in
monitor SKILL.md and VERSIONS.md (a running --once pass finishes first,
the interval's sleep child ends on its own); create SKILL.md says an
already-running daemon's PID is still reported under the opt-out;
VERSIONS selector wording and test count (14).

Review round 1 (claude PASS, agy PASS) recommendations:
- reconcile.sh: `_sub_stop` falls back to `$!` for the window before
`_sub_pid=$!` (R-1); lock identity compared as (st_dev, st_ino).
- lib.sh legacy start_watchdog prints nothing when opted out and no daemon
runs, byte-identical to the python body.
- conftest/test: `_is_subscriber_daemon_argv` selects only
`bash|sh <root>/.../reconcile.sh --subscribe`, never a brief-carrying
wrapper that quotes the words or a prefix-colliding sibling root (R-2);
one new unit test for the selector.
- monitor SKILL.md / VERSIONS.md: the polling fallback checks the lock
file's presence only and does not exclude a second daemon; measurement
wording uses the argv-shape criterion instead of raw pgrep.

create_session.sh detaches `reconcile.sh --subscribe --idle-timeout 0` per
workspace; test sandboxes never reaped it and the daemon neither noticed its
workspace vanish nor honoured SIGTERM (bash deferred the signal behind the
foreground python child). 202 orphans were found holding public-broker
wildcard subscriptions for deleted pytest tmpdirs.
- daemon.py / lib.sh: MAM_NO_SUBSCRIBER_DAEMON=1 (literal) skips the spawn but
still reports a running daemon; cli prints a stderr note, stdout stays empty.
- reconcile.sh: python subscriber runs as a waited background child with a
TERM/INT trap (exit 143); the MQTT loop exits when the workspace dir is gone
or .mam/monitor.lock is no longer the held inode; SIGTERM/SIGINT handled via
the stop event so loop_stop/disconnect run; the polling fallback checks the
same and sleeps in a waited child.
- conftest: sandbox default MAM_NO_SUBSCRIBER_DAEMON=1, per-sandbox reaper
finalizer, session-scope leak guard over the pytest basetemp.
- tests: 11 lifecycle tests (tests/test_issue19_subscriber_daemon_lifecycle.py);
phase-1 watchdog/daemon characterization tests opt back in.
- docs: monitor SKILL.md lifecycle contract + pitfalls, create SKILL.md note.

- Drop per-session agent runtime markers (CLAUDECODE, CLAUDE_CODE_CHILD_SESSION,
CLAUDE_CODE_SESSION_ID, Claude Code messaging/bridge/pid markers, and the
agy/hermes/grok/opencode session ids) from the environment lib.sh's shim hands
to a bootstrapped `herdr --session <name> server`; user configuration such as
CLAUDE_PROJECT_DIR still inherits
- Add MAM_NO_AUTOSTART=1 so query-only callers never bootstrap a server as a side
effect; status.sh and reconcile.sh export it, and the shim's `ls` reports a down
server as "no server running" so reconcile keeps herdr_confirmed instead of
freezing drift detection for every server
- send_keys_safe: treat `timeout` / `agent_prompt_stalled` from `agent prompt
--wait` as an accepted submission and confirm delivery for SKS_DELIVERY_GRACE_S
(default 15 s) via agent_status working, a busy token the pane did not show
before, or the pane moving on from its pre-submit snapshot; no signal at all
still fails closed (rc 4). Codex under herdr 0.9.0 never reports `working`, so
every delivered prompt was closed as agent_blocked and its later
started/completed events refused
- delegate wrapper: before closing an unconfirmed inject as agent_blocked, honour
the registry's own acknowledgement for MAM_INJECT_ACK_GRACE_S (default 10 s)
- Switch T1-7's failure trigger to transport_error (timeout now means accepted);
add test_issue9_server_env.py (5 cases) and test_issue14_delivery_ack.py (7)
- Verified live: a freshly bootstrapped multi-agent-mux server carries no markers
and the claude panes save transcripts again; codex job d04ebcb5 had its

Issue #5 (Python core migration, CAS state transitions, shadow watcher,
auto-completion gate, eager-import immutable runtime, B-13 freeze removal)
is complete and merged to main. This stamps the release.
SemVer: MINOR, not MAJOR. The change is large but breaks nothing. Across the
whole Issue #5 range there are zero file deletions and zero renames, the event
wire schema stays at SCHEMA_VERSION 1, all four literal script paths survive as
compatibility shims, the 968-line legacy shell loop is still in run_loop.sh,
and every default change reverts through a single environment variable
(MAM_DELEGATION_PY / MAM_ENGINE_CAS / MAM_LOOP_PY / MAM_LOOP_FREEZE). The
riskiest new feature, auto-completion, ships default-off. No operator has
anything to migrate, which is the decisive reason not to call it 5.0.0. The
reasoning is recorded in the VERSIONS.md release notes, not just here.
Close a gap in the lockstep guard. lib.sh exports MAM_VERSION and eager_load()
refuses to start the loop when it disagrees with FRAMEWORK_VERSION, so eager.py
is a load-bearing fourth leg — but test_version_consistency.py only checked
three, and the sole check on eager.py was a hardcoded literal in the phase 4
test that a release bump has to edit anyway. The lockstep test now covers
eager.py, a new test pins the fail-closed gate itself, and the phase 4 test no
longer carries a version literal.
Fix a latent test-isolation defect the bump exposed. The first full run failed
four tests with "MAM_VERSION mismatch: expected 4.4.0, got 4.3.0 in
environment" — 4.3.0 was not in the tree, it was inherited from the shell that
launched pytest and had sourced the pre-bump lib.sh. Those tests were measuring
the runner's shell rather than the tree under test, and only passed until now
because the two values always happened to agree. A session-scoped fixture drops
the ambient value. Production is unaffected: run_loop.sh:17 sources lib.sh
before anything else and lib.sh re-exports MAM_VERSION unconditionally, so a
stale inherited value is always overwritten before Python starts.
Full suite: 750 passed in 912.50s, 0 failed, 0 skipped.

Records the measured numbers and syncs every document that names the
delegation script paths, then bumps the framework to 4.3.0 in the three-way
lockstep (lib.sh, VERSIONS.md current + matrix, eight SKILL.md frontmatters).
phase1-benchmark.md carries both arms. The deterministic fake transport is what
CI asserts on: 50 publishes cost 50 connections one-shot and 1 persistent, p50
54.813ms -> 0.002ms. The real broker run is informational, since the PoC
default is a public broker: p50 1892.728ms -> 275.992ms, about 85% off.
It also corrects the plan's own estimate rather than repeating it. D8 predicted
the new shell path would drop from 3 forks to 2; the implementation is still 3,
because keeping the `_delegate_script publish_event.py` lookup is the only
thing that produces the "missing script tree does nothing" non-fatal contract
that C-02 pins. Saving that fork would change the contract, so it is deferred
to phase 4 rather than taken quietly.
SKILL.md gains the context table saying which tree wins where, so an operator
reading it knows a frozen loop runs frozen delegation code. The script paths in
every document remain correct and every quoted command still works verbatim.

The four delegation scripts become a real package. Their old paths stay as
shims because those paths are a wire contract: agent instructions, the bash
wrapper, SKILL.md, BOOTSTRAP.md, deploy/install.sh and three test modules all
call them literally.
The shim binds the lib_py.delegation *package* to the tree beside it, once per
process, and never touches sys.path. Two cheaper designs were rejected with
evidence (the context matrix now lives in the test suite):
* inserting the sibling skills dir at sys.path[0] makes the first sandbox
copy imported under pytest shadow lib_py.agents/layout/state for the whole
session, and the identity assertion cannot see it -- `is` proves same
object, not same tree.
* loading only the named module by file path leaves a module that imports
siblings pulling them from whichever tree is on the path, so a frozen
publish_event ran against live dependencies and lost half of B-13.
Binding the package fixes both: one tree for all delegation modules, the parent
lib_py untouched, and a sys.path append only when no lib_py exists anywhere
(true standalone). Bind-once rather than nearest-wins, because rebinding would
split existing references and break monkeypatching.
Also moves the env-file load off import (_load_dotenv -> ensure_env_loaded,
called by each process entry point including reconcile.sh's embedded
subscriber), so importing the library no longer mutates os.environ.
Verified: PV-1 identity+provenance, PV-4's ten import scenarios plus K1/K3/K6
in fresh interpreters, PV-5 shim byte-identity, an AST check that the package
imports no sibling lib_py module, and --help output diffed against the
pre-move capture.
