These workplans exist only in the retired local hub. Their random pre-ADR-007 identifiers are refused by C-06 as stale references, so they cannot be registered. Deriving from the canonical record id takes no identity from anything: central does not hold them and the old ids die with the cache. Records central already holds were deliberately left untouched.

# RCLUSTER-WP-0014 — cluster resource evidence
|
|
|
|
## Goal
|
|
|
|
Publish reproducible non-secret evidence for
|
|
`resource:railiance:reef-railiance:k3s`: capacity, requested and observed
|
|
utilization, persistent-storage exposure, failure domains, and allocation
|
|
drivers. Origin: `RESOURCE-WP-0003-T04` delegated evidence gap.
|
|
|
|
This is ADR-0006 reef evidence (capacity headroom, failure-domain
|
|
assumptions). It does not promote a binding to `production-approved`.
|
|
It does not publish a public metrics listener (ADR-0008). Collect
|
|
in-cluster or via the operator tunnel.
|
|
|
|
Current reality: one Ready node (`railiance01`), local storage, Traefik.
|
|
Do not invent a three-domain map or report Longhorn as live capacity.
|
|
`RAIL-BS-WP-0007` is the HA *target*.
|
|
|
|
S2 publishes facts. `reef-railiance` cites them. `resource-control` /
|
|
fin-hub allocate. No booked EUR in this repo.
|
|
|
|
## T01 — Produce periodic cluster capacity observations
|
|
|
|
```task
|
|
id: RCLUSTER-WP-0014-T01
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "abc4980e-4103-5d63-9e05-5a198dc7988b"
|
|
```
|
|
|
|
Collect node count, allocatable CPU/memory/storage/pods, workload requests and
|
|
limits, observed usage when metrics are available, and PVC requested capacity.
|
|
Aggregate by namespace/workload without exposing Secret data or pod
|
|
environment. Preserve observation time, cluster identity, units, unavailable
|
|
metrics, and source commands.
|
|
|
|
Done when repeated observations use a stable machine-readable interface and
|
|
resource-control can distinguish headroom, reservations, and actual usage.
|
|
|
|
**Outcome (2026-08-22):** `make cluster-observe REMOTE=railiance01` now emits
|
|
versioned, timestamped JSON with node allocatable/observed resources,
|
|
namespace/workload requests and limits, PVC/PV/storage-class state, stable
|
|
units, source commands, and explicit gaps without reading Secrets or pod
|
|
environments.
|
|
|
|
## T02 — Publish the failure-domain and storage contract
|
|
|
|
```task
|
|
id: RCLUSTER-WP-0014-T02
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "9e0dc15e-a853-512e-be44-71525ce0bc47"
|
|
```
|
|
|
|
Expose the current node-to-host/provider failure-domain map and the actual
|
|
storage-class/PVC durability contract. Link the target ThreePhoenix work in
|
|
`RAIL-BS-WP-0007` without reporting target nodes or distributed storage as
|
|
current capacity.
|
|
|
|
Done when consumers can calculate correlated-failure risk and recognize which
|
|
state remains local to `railiance01`.
|
|
|
|
**Outcome (2026-08-22):** the evidence contract reports one Ready node,
|
|
`local-path` storage, `threephoenix_ready: false`, and the missing independent
|
|
region/zone labels. Target HA and Longhorn capacity are not represented as
|
|
current facts.
|
|
|
|
## T03 — Define technical allocation-driver evidence
|
|
|
|
```task
|
|
id: RCLUSTER-WP-0014-T03
|
|
status: done
|
|
priority: medium
|
|
state_hub_task_id: "8a052726-e6f2-5852-aada-a14e67bca695"
|
|
```
|
|
|
|
Evaluate namespace/workload CPU-request hours, memory-request hours, PVC
|
|
GB-month, and observed usage as allocation drivers. Publish numerator,
|
|
denominator, residual/unallocated capacity, method version, and uncertainty;
|
|
do not convert the result into booked spend.
|
|
|
|
Done when resource-control can create an explainable allocation and fin-hub can
|
|
reconcile it to referenced financial facts.
|
|
|
|
**Outcome (2026-08-22):** `cluster-raw-drivers-v1` publishes CPU requests,
|
|
memory requests, PVC bytes, observed usage, totals, residual capacity, and
|
|
uncertainty, while leaving formula selection and booked cost to
|
|
`resource-control`.
|
|
|
|
## Acceptance
|
|
|
|
- [x] Capacity evidence separates allocatable, requested, limited, and observed.
|
|
- [x] Current single-host/local-storage risk is machine-readable.
|
|
- [x] Allocation drivers reconcile to explicit totals and residuals.
|
|
|
|
## Completion evidence
|
|
|
|
- `python3 -m unittest discover -s tests -p 'test_*.py' -v`: 2 tests passed.
|
|
- Live read-only capture:
|
|
`docs/evidence/resource-reef-railiance-k3s/observations/20260822T100349Z.json`.
|
|
- Observed totals: 1 node, 53 workloads, 25 claims; 4,000m allocatable CPU,
|
|
3,830m requested CPU, 16,770,076,672 allocatable memory bytes, and
|
|
137,438,953,472 requested PVC bytes.
