Merge pull request 'fix(alignment): resolve /root/ hardcoding and stale tanko-DSH references' (#147) from fix/agent-health-root-hardcoding-20260928 into master

The fleet's wrappers do not all use a hermes-real indirection. Some (tanko,
mumuni) exec the venv module directly. This check now:
  1. Tries hermes-real at {home}/.local/bin (koonimo's shape)
  2. Tries the venv under {home}/.hermes/hermes-agent/venv (tanko/mumuni shape)
  3. Tries /usr/local/lib/hermes-agent/venv (legacy system-wide shape)

Each match is reported with which shape it matched, so a genuinely broken
wrapper is still a failure while a different-but-valid shape is not.

 ## Purpose
 Auto-fix low-hanging fruit in the graph. No judgment calls — only deterministic Level 1 operations. Escalate anything that needs Kwame's input. When Kwame replies to an escalation, **execute the decision to completion** (update state and timestamps), never leaving a node in review-pending forever.

+### 5. Duplicate-Node Detection (Level 1 — read-only, every run)
+
+The graph's duplicate problem is rarely an agent mistyping a title: it is **recurring writers creating a new
+node per run instead of updating one**. This phase detects that class and reports it. It is read-only and
+**never merges**.
+
+```bash

+```

+do not re-implement it in the prompt or hand-count "duplicates" from titles.
+
+Consume each `items[]` entry's `verdict` field; do not invent your own:
+
+| `verdict` | Meaning | Required action |
+|---|---|---|
+| `WRITER-DEFECT` (`run_family: true`) | ONE scheduled task writes a new node per run | Report the ids, the `agents` (the writer) and `span_days`. **Never merge** — each node is that run's audit record. If the family grew since the last report, say `UNFIXED` and name the writer. |
+| `SAFE-MERGE` | Bodies identical | Still requires an explicit `merge #A into #B` decision from Kwame. |
+| `HUMAN-DECISION` | Same subject, bodies differ | Propose **connect (an edge)**, never merge. |
+
+- **Title overlap alone is not duplication.** Four distinct client workflows of one family (#357-#361) and two
+  different machines' migrations (#1792/#1793) both score high on title tokens while their bodies sit 0.1-0.3
+  apart. Confirm against body similarity before calling anything a duplicate.
+- Report clusters as **candidates for Kwame's decision**, never as established duplicates — a wrong auto-merge
+  destroys distinct content irrecoverably.
+- Per-run history nodes are kept deliberately. Bulk-merging a run family destroys the audit trail the family exists for.
+
 ## Level 2 Escalations (Kwame Decision Required)
 
 1. **Refresh-suggested stale nodes** flagged with `[REVIEW: refresh]` — refresh or keep? (Archive-suggested nodes are auto-archived under fix 4 and are not escalated.)
-2. **Duplicate Nodes** (same title or >70% title overlap) — Merge or keep?
+2. **Duplicate Nodes** — as detected by fix 5, by `verdict`, never by raw title overlap. `WRITER-DEFECT` is a writer fix (update one canonical node), not a merge decision; `SAFE-MERGE` and `HUMAN-DECISION` clusters are escalated for merge-or-connect.
 3. **Orphan Nodes >90 days old** — Archive or connect?
 
 ## Reporting Format
 
-The fixer reports to Kwame via this Zulip DM:
+The fixer does **not** send anything. Under the single-egress model (2026-09-21) every report leaves the node
+through Mumuni's gate (`comms_drop.py` for the queue, `comms_gate.py` to release and read-back verify), so
+exit 0 means QUEUED, never delivered. A report body is written to a file and handed to the outbox helper:

+"""Regression test for the fallback_providers list-shape crash in audit-hermes-config.py.
+
+WHY THIS FILE EXISTS: audit-hermes-config.py assumed `fallback_providers` was always a dict
+(single provider). Two live agents (koby, koonimo) carry it as a LIST of dicts (one entry per
+fallback), so the script crashed with:
+
+    File "audit-hermes-config.py", line 211, in audit
+        fb.get("provider") == "deepseek",
+    AttributeError: 'list' object has no attribute 'get'
+
+Both are REAL agent configs, so this is not a malformed-input case — the script simply could not
+audit two of the four agents it exists to audit. Until fixed, the key-hygiene check had no
+coverage for half the fleet while appearing to run.
+
+These tests execute the real CLI (`python3 audit-hermes-config.py <config>`) and assert:
+1. A config whose `fallback_providers` is a LIST of valid dicts does NOT crash (exit code is 0 or 1,
+   never a traceback/AttributeError).
+2. A config whose `fallback_providers` contains a MALFORMED entry (a list element that is not a
+   mapping) reports a VIOLATION naming the offending entry, NOT an uncaught exception.
+3. The dict shape still works (existing tests must stay green).
+
+No network, vault, or SSH access is required.
