POTESTAS 6.1 — event types and ledger format for the track

[4444J99]

Phase: #2084 · Program: #2077

Wire POTESTAS into studium's existing analysis spine. Do not build a second one.

Event types

Add to studium/analysis/events-schema.yaml:

• mechanism_observed — {mechanism: <registry id>, channel: <medium class>}. A named mechanism was recognized in the wild. This is the program's core signal: it measures recognition, which is the actual trained skill.
• drill_run — {family: <mechanism family>, named_correctly: bool}. Inoculation practice.
• decision_deferred — {class: financial|commitment|scope}. The financial-decision protocol (Φ4 POTESTAS — DEPLOYMENT (prestige route): the two named training failures #2082 → 4.2) held: a decision was moved off a synchronous channel. The one event that records a protocol working rather than a failure being observed.

Also add disclosure and negotiation to the rubric enum for the rubric_score event.

Posture — inherited, non-negotiable

From the schema's own header: append-only, local-first, non-PII. actor is self. Never a name, email, handle, or message body — only the structured fields above. Community-scale collection stays consent-gated.

mechanism_observed records the mechanism id, never who did it. That constraint is what keeps the event stream a record of a skill developing rather than a dossier on a person, and it is the structural mitigation for this program's named failure mode.

Ledger

POTESTAS entries use the existing studium/ledger/studium-YYYY-MM-DD.md per-day format. No new ledger, no new cadence, no automation. Self-scored, slow.

Why decision_deferred matters most

Every other event in this program records something being noticed. That one records something being done differently. It is the only event whose count going up means the training worked rather than that the observer got more sensitive.

Done

The three event types and both rubric names are in events-schema.yaml, the ledger format carries POTESTAS entries, and no event field can hold identifying free text.
