# Cadence Recommendation — Deferred Deliverable Marker

This file is a **placeholder marker**, not the recommendation doc itself. It documents that `references/vault-maintain-cadence.md` is a deferred deliverable awaiting telemetry data.

## Status

**FOUND-05 cadence recommendation doc is decoupled from the v1.5.3 milestone calendar.** It ships as a free-floating deliverable when the telemetry threshold is met, regardless of which milestone is active at that time.

## What this file replaces

The original v1.5.3 plan was for `references/vault-maintain-cadence.md` to ship at the close of Phase 49. The plan was data-gated on `records ≥ 50 AND days_elapsed ≥ 7`. Investigation on 2026-05-04 revealed the calendar-side criterion was unmeasurable by instrumentation design (vault-maintain --core fires only at workflow boundaries; idle days produce zero records). The records-side criterion was preserved but cannot be hit organically within v1.5.3 close-out trigger budget.

Per Option α discipline (data-driven, not data-shaped), the gate was amended to records-only and the deliverable was decoupled from the milestone calendar.

## How to ship the actual recommendation doc

When telemetry records reach ≥ 50, run:

```bash
node -e "const r=require('fs').readFileSync('.vault/.telemetry/maintain-cadence.ndjson','utf8').split('\n').filter(l=>l.trim());console.log('records:',r.length,'/50','ready:',r.length>=50);"
```

If `ready: true`, run:

```
/gmd:execute-phase 49 --plans 49-06
```

The executor will follow the amended Plan 49-06 (Case A branch): author `tests/audit-cadence-recommendation-doc.sh` (mutation-tested 4-case audit) and `references/vault-maintain-cadence.md` (per-subsystem cost data + boundary-conditional catch-rate + cost-driven keep/relax/remove guidance). Idle-day cadence claims remain explicitly out of scope per amendment.

When the recommendation doc lands, this marker file is superseded. Delete it as part of the same commit that ships `references/vault-maintain-cadence.md`.
