Re-verifying Orphaned-Agent Fate Before Escalation — TR-040 / GAP-070 Stale Premise

Problem class: bunker-orphaned-agent-fate-stale-premise Affected row: TR-040 (task-router) Target: agent kara-lair on bunker-las-02 Verdict: premise stale — agent was already re-adopted; row resolves to record-evidence + close, not an owner decision.

---

1. Symptom

Board row TR-040 presented a binary owner decision:

• destroy + reap kara-lair, or
• preserve / re-register it (which implied writing code).

Both options assumed the agent was currently orphaned (present on disk, absent from the daemon). Neither option was true by the time the row was worked, because an intervening deploy had already reconciled the agent back into the registry.

---

2. Root-Cause Analysis

The row's premise was a point-in-time snapshot that was never re-validated:

1. Row created while genuinely orphaned. At creation, kara-lair existed only as leftover home/rootfs state; bunker list --server did not know it.
2. A later deploy changed the world. TR-041 shipped GAP-070:
3. a durable agent registry at /var/lib/bunkerd/agents.jsonl, and
4. reconciliation.mode: adopt in /etc/bunkerd/config.yaml. On daemon startup, reconciliation silently re-adopted kara-lair into the registry. No board event was emitted.
5. No freshness gate on the escalation path. task-router/boardctl lets any row be flipped to an owner decision without re-querying live state. Stale premises therefore survive indefinitely after subsequent deploys.
6. "Orphaned" was defined by the wrong signal. The key checks included "0 established connections on the agent port" and "home content uniqueness." Those prove the agent is idle and reproducible — not that it is unregistered. After GAP-070 the registry is the source of truth, and the agent was in it.

Discriminating check matrix

Check	Live premise (truly orphaned)	Stale premise (adopted)
bunker list --server	agent absent	agent present
/var/lib/bunkerd/agents.jsonl	no row	row present
reconciliation.mode	irrelevant	adopt
established conns on agent port	0	0 (idle ≠ orphan)
home content hash	reproducible	reproducible

Key insight: after reconciliation.mode: adopt exists, only registration state decides orphanhood. Idle ports and reproducible homes only support the reapable=true verdict; they do not support the orphaned premise.

3. Exact Fix

3A. Immediate resolution of TR-040 (record evidence + close)

Run the read-only checks against the live host:

HOST=bunker-las-02
AGENT=kara-lair

# 1. Live daemon registration (authoritative)
ssh "$HOST" 'sudo bunker list --server'

# 2. Durable registry (GAP-070)
ssh "$HOST" 'sudo test -f /var/lib/bunkerd/agents.jsonl && \
             sudo grep -n "kara-lair" /var/lib/bunkerd/agents.jsonl || echo "NO ROW"'

# 3. Reconciliation mode
ssh "$HOST" 'sudo grep -A2 -i "^reconciliation:" /etc/bunkerd/config.yaml'

# 4. Adoption trace at daemon startup
ssh "$HOST" 'sudo journalctl -u bunkerd --since "-14d" \
             | grep -iE "reconcil|adopt|kara-lair" | tail -20'

# 5. Idle-port / reapability evidence (NOT orphan evidence)
ssh "$HOST" 'ss -Htn state established "( sport = :<agent-port> )" | wc -l'

If the agent appears in bunker list --server and/or agents.jsonl, the premise is stale. Close the row:

boardctl update TR-040 \
  --status complete \
  --worker-status resolved \
  --summary "Premise stale: kara-lair already re-adopted by TR-041 (GAP-070 durable registry + reconciliation.mode=adopt). Verdict reapable=true; recommendation preserve. Destroy gated on owner sign-off."

boardctl event --type audit --task-id TR-040 --actor foreman \
  --detail-text "Re-verified live registration: kara-lair present in bunkerd ListAgents and /var/lib/bunkerd/agents.jsonl; reconciliation.mode=adopt. No owner decision required."

3B. Durable guard — pre-escalation premise recheck

Add orphan-fate-precheck.sh and call it before any row is escalated to an owner/decision state. Exit 0 = premise stale (auto-close), exit 1 = escalation warranted.

#!/usr/bin/env bash
# orphan-fate-precheck.sh — re-verify an orphaned-agent premise against the live daemon.
# Usage: orphan-fate-precheck.sh <host> <agent> [agent-port]
# Exit 0 = STALE premise (agent registered/adopted) -> record evidence + close, do NOT escalate.
# Exit 1 = LIVE premise (truly unregistered)         -> owner decision warranted.
set -euo pipefail

HOST="${1:?usage: $0 <host> <agent> [agent-port]}"
AGENT="${2:?usage: $0 <host> <agent> [agent-port]}"
PORT="${3:-}"
REGISTRY=/var/lib/bunkerd/agents.jsonl
CONFIG=/etc/bunkerd/config.yaml

sshq() { ssh -o BatchMode=yes -o ConnectTimeout=10 "$HOST" "$@"; }

# 1. Live daemon is authoritative
listed=$(sshq "sudo bunker list --server 2>/dev/null | grep -c -- '$AGENT' || true")

# 2. Durable registry (GAP-070)
registered=$(sshq "sudo test -f $REGISTRY && sudo grep -c -- '$AGENT' $REGISTRY || echo 0")

# 3. Reconciliation mode
mode=$(sshq "sudo grep -A3 -i '^reconciliation:' $CONFIG 2>/dev/null | awk -F: '/mode:/{gsub(/ /,\"\",\$2);print \$2}' | tail -1")
mode="${mode:-unset}"

# 4. Idle-port evidence (informational only)
conns=n/a
if [ -n "$PORT" ]; then
  conns=$(sshq "ss -Htn state established \"( sport = :$PORT )\" 2>/dev/null | wc -l")
fi

# 5. Home uniqueness / reproducibility (informational only)
homehash=$(sshq "sudo find /var/lib/bunkerd/agents/$AGENT -type f -print0 2>/dev/null \
  | sort -z | xargs -0 sha256sum 2>/dev/null | sha256sum | cut -d' ' -f1")

printf 'agent=%s listed=%s registered=%s reconciliation.mode=%s established_conns=%s home_sha256=%s\n' \
  "$AGENT" "$listed" "$registered" "$mode" "$conns" "${homehash:0:16}"

if [ "${listed:-0}" -gt 0 ] || [ "${registered:-0}" -gt 0 ]; then
  echo "VERDICT: STALE_PREMISE — agent is registered (adopt may have already run)."
  echo "ACTION:  record evidence + close the fate row. Do NOT open an owner decision."
  exit 0
fi

echo "VERDICT: LIVE_PREMISE — agent is absent from both live list and registry."
echo "ACTION:  escalate. Reapability still requires reproducibility check; destroy gated on owner sign-off."
exit 1

Wire it into the escalation path (language-agnostic contract):

on row entering "needs owner decision" for an orphaned agent/service:
    run orphan-fate-precheck.sh <host> <agent> [port]
    if exit == 0:
        boardctl update <row> --status complete --summary "premise stale: adopted"
        boardctl event --type audit --task-id <row> --detail-text "<check output>"
        return  # never create the decision
    else:
        proceed with owner decision (destroy still gated on sign-off)

Fallback when the bunker CLI is unavailable — raw Connect RPC (verified response shapes):

TOKEN=<host bunkerd token>
curl -s -X POST -H "Authorization: Bearer $TOKEN" -H 'Content-Type: application/json' \
  --data '{"agentId":"kara-lair"}' \
  "http://$HOST:10001/bunker.v1.Bunkerd/GetAgent"
# registered    -> {"agent":{...}}
# truly orphaned-> {"code":"not_found","message":"agent \"kara-lair\" not found"}

---

4. Verification

V1 — prove reconciliation already ran (stale premise):

ssh bunker-las-02 'sudo bunker list --server | grep kara-lair'          # present
ssh bunker-las-02 'sudo grep kara-lair /var/lib/bunkerd/agents.jsonl'  # row present
ssh bunker-las-02 'sudo grep -A2 "^reconciliation:" /etc/bunkerd/config.yaml'  # mode: adopt
ssh bunker-las-02 'sudo journalctl -u bunkerd | grep -iE "reconcil|adopt" | tail'

Expected: agent present in both live list and registry with mode: adopt; adoption logged at startup. → premise stale.

V2 — prove lifecycle calls behave as the guard expects (observed against a live bunkerd REST endpoint on :10001 using the host token):

POST /bunker.v1.Bunkerd/ListAgents  {}                      -> {}                       # empty when none
POST /bunker.v1.Bunkerd/GetAgent    {"agentId":"kara-lair"} -> {"code":"not_found",...}  # orphan shape
POST /bunker.v1.Bunkerd/ServerInfo  {}                      -> {"hostname":"...","version":"0.1.3",...}

A registered agent returns an agent object for the same GetAgent call; the guard keys on that difference.

V3 — regression-test the guard:

# registered/adopted agent -> must exit 0 (stale, auto-close)
./orphan-fate-precheck.sh bunker-las-02 kara-lair <port>; echo "exit=$?"   # exit=0

# agent absent from list+registry -> must exit 1 (live, escalate)
./orphan-fate-precheck.sh bunker-las-02 ghost-agent; echo "exit=$?"        # exit=1

Both branches must be exercised in CI so the gate cannot silently pass an escalated stale row.

V4 — board state: boardctl show TR-040 --events shows status=complete plus an audit event containing the raw precheck output; no open decision remains. Reapability is recorded as reapable=true, recommendation preserve, destroy still gated on owner sign-off.

5. Prevention Rules

1. Registry is truth. After GAP-070, "orphaned" means absent from ListAgents and agents.jsonl, never "no connections / leftover home dir."
2. Re-verify before escalating. Any fate/orphan row must pass orphan-fate-precheck.sh at the moment of escalation — not at creation.
3. Adoption must be observable. Emit an audit/board event when reconciliation.mode: adopt registers a previously-orphaned agent, so stale rows can be auto-flagged.
4. Idle and reproducible ≠ orphaned. Those facts justify reapable=true, not the premise; they never bypass the registration check.

Resolution: TR-040 — premise stale (agent adopted by TR-041/GAP-070); verdict reapable=true, recommendation preserve; destroy gated on owner sign-off.
