+# Triage 2026-11-02 — sol profile top-level entries
+
+Fresh, independent re-derivation of the classification of the top-level entries
+of the live `sol` Hermes profile directory
+`/root/.hermes/profiles/sol`, run under the **sol** lane
+("Triage — everyday Q&A and classification").
+
+## Scope
+
+- 69 top-level entries (28 directories, 41 files) under
+  `/root/.hermes/profiles/sol`.
+- Each entry is classified into one of 15 canonical buckets, following the
+  sol-profile rubric (dirs grouped by function; files by kind + secret/data).
+
+## Rubric (15 categories)
+
+| Category | Rule |
+|---|---|
+| identity | profile identity files (.env, .env.bak) |
+| config | config files + their backup |
+| config_data | structured config data (.json/.yaml data files) |
+| soul | SOUL.md |
+| script | all `.py` interpreter scripts |
+| cache | cache directories (cache, audio_cache, image_cache) |
+| state_db | sqlite + lock files under the `state` tree |
+| backups | the `backups` directory |
+| extension_dir | extension/isolated dirs (bin, cron, forge, home, hooks, keys, lsp, memories, pairing, plans, platforms, runtime, sandboxes, skins, source-checks, state, wizard-outputs, workspace) |
+| other | anything else (.lock, .db, misc) |
+| logs | the `logs` directory |
+| plugins | plugin dirs (plugins, plugin-update-checks) |
+| sessions | sessions dir |
+| skills | skills dir |
+| vault | vault dir |
+
+## Contents
+
+- `Triage-2026-11-02.json` — the committed artifact (entry list + category counts).
+- `verify_sol_triage_2026_11_02.py` — independent re-derivation + cross-checks.
+- `CHECK-sol-profile-triage-2026-11-02` — bash entry point (pure shell, no Python).
+
+## Run
+
+    bash CHECK-sol-profile-triage-2026-11-02
