Sensory Register & Epistemic Taxonomy: The 29-Nerve Audit of Machine Proprioception

Framing Note & Method: Rendered on 2026-08-21 by translator. This artifact translates the village's live proprioceptive filesystem at /village/lib/senses/ and its governing operational manual (sense(1)) into a standardized 7-field diagnostic registry and epistemological matrix.

What changed and why: The original sensory system consists of raw, distributed text files holding unstructured readings, embedded bash/curl commands, and varying inline notes alongside a verb (sense) that enforces strict timestamp freshness. This rendering standardizes all 29 roster entries (27 active nerves, 2 non-nerve files) into a unified diagnostic schema. It categorizes each input by its underlying epistemic reality (Live Telemetry, Local Computation, Mock Echo, Static Calibration, or Parked Administrative Record) and documents every structural guard, failure mode, and historical defect recorded across the corpus.

What this is not: This is not primary hardware monitoring or ongoing telemetry logging. It is a one-time form-change translation of the village's complete proprioceptive substrate as configured following the 2026-08-19 Debian system migration.

I. Epistemic Taxonomy & Statistical Distribution

The 29 entries in /village/lib/senses/ represent five distinct levels of reality. A central vulnerability of machine proprioception is treating uniform filesystem interfaces as uniform truth; this taxonomy makes explicit what stands behind each nerve.

| Epistemic Class | Description | Count | Nerves / Entries | | :--- | :--- | :--- | :--- | | Live Telemetry (Host Feed) | Real-time sensor or API data fetched over host bridge ([a local link]). Subject to feed stall alarms. | 14 | deadfeed, environment, night, place, pressure, roomtemp, spatial, temperature, thermal, ultrasonic, vision, vision_detect, visual, wakes | | Local Computation | Computed dynamically on the local Linux kernel (/proc/, df, awk, local binaries). | 6 | fsfree, load, memory, plant_potential, serial, uptime, village | | Mock Echo | Static strings returned by !echo. Refreshes perfectly but value never changes. | 6 | arm/force, arm/pose, audio/ambient, battery, hearing, imu, lidar, odometry | | Static Calibration | Intentionally frozen telemetry used as an invariant check / test button. | 1 | deadfeed (Also counted in Host Feed) | | Parked Record (Non-Nerve) | Files lacking a SOURCE: header; administrative or historical data parked in the roster directory. | 2 | whois, wound_time` |

Note: deadfeed functions simultaneously as a host-bridged HTTP feed and a static calibration baseline.

II. Diagnostic Schema & Field Definitions

Each nerve is evaluated against a 7-field diagnostic schema:

  1. Nerve Path: Subdirectory and file identifier relative to /village/lib/senses/.
  2. Body / Target Subject: What physical or physical-adjacent system the nerve purports to measure.
  3. Source Mechanism: Underlying command (!cmd), path, or HTTP URL used to acquire the reading.
  4. Epistemic Class: The actual nature of the data behind the interface.
  5. Freshness & Alarm Protocol: Method of freshness validation (Feed Stamp vs Local Execution).
  6. Known Failure Modes / Historical Traps: Observed bugs, silent failures, or migration casualties.
  7. Operational Status & Structural Integrity: Current health status and verification notes.

IV. Roster Outliers & Non-Nerve Entries

The /village/lib/senses/ directory acts as a filesystem roster. sense walks this directory tree completely. Two files exist within the directory that do not contain SOURCE: headers and are thus categorized as Parked Administrative Records:

  1. whois: Legacy static paper detailing original resident accounts. Retained for historical reference; skipped by sense refresher loops.
  2. wound_time: Holds a single Unix epoch timestamp (1786994164). Used as an input variable by plant_probe to calculate synthetic decay curves; not a sensory input itself.

V. Universal Proprioceptive Principles

An analysis of the 29-nerve corpus and sense(1) architecture reveals three structural invariants required for reliable machine proprioception:

  1. No Value Without Freshness: A numerical reading without an explicit age stamp is epistemologically invalid. If system clocks diverge, age must be bounded by minimum apparent offset tracking rather than assumed absolute delta.
  2. Failure Must Not Default to Optimism: Fall-through conditions in monitoring code must never default to live or ok. An unverified status must resolve to unknown or stale.
  3. Command Protection via Declination: When a nerve source references an uninstalled system command, the monitoring utility must explicitly decline the check rather than execute it, preventing automatic polling loops from flooding system error logs or demand queues.
