v2.5.3

> **Deprecated (2026-10-04):** this release pins a `hermes-agent` image tag that no longer exists, so installing it fails. It is also affected by [GHSA-vqpg-pvjj-4cmq](https://github.com/Osmantic/ODS/security/advisories/GHSA-vqpg-pvjj-4cmq) and [GHSA-v3hj-52g2-2hmc](https://github.com/Osmantic/ODS/security/advisories/GHSA-v3hj-52g2-2hmc). Install from the [README](https://github.com/Osmantic/ODS#get-started) instead.

## Fixed

- Owner-card readiness now notices `dream-proxy` after `dream enable dream-proxy` and `dream start dream-proxy` without requiring a manual `dashboard-api` restart.

## Validation

- Fleet test run on 2026-05-26 at commit `cff3b21` validated the #1474 fix and passed regressions, zero-prereq bootstrap, install, verify, cloud-mode, dashboard, Hermes, UI, lifecycle, and distro lab validation across tower2, Strix Halo, Spark, and M5 MacBook Pro.
- The new `dream-proxy-owner-card-readiness-1474` regression fixture passed on Strix Halo from both already-enabled and disabled states, proving owner-card status returns `ready: true` without restarting `dashboard-api`.
- Capability reruns confirmed the initial Strix Halo and M5 MacBook Pro failures were model/timing flakes; full-model capability probes passed on Strix Halo and M5 MacBook Pro, while tower2 and Spark correctly deferred LLM-driven full-model probes on bootstrap models.
- Distro lab passed 10/10 Docker lanes and 5/5 Incus VM lanes.

Enabled fleet hosts:

- `tower2`: NVIDIA Blackwell x86, bootstrap model at capability probe time; install, product, UI, lifecycle, and non-LLM capability checks PASS
- `strix-halo`: AMD/Lemonade, `Qwen3.6-35B-A3B` full-model capabilities PASS on rerun
- `spark`: NVIDIA GB10 aarch64, bootstrap model at capability probe time; install, product, lifecycle, and non-LLM capability checks PASS
- `m5-mbp`: Apple M5 Max, `Qwen3.6-35B-A3B` full-model capabilities PASS on rerun

Notes:

- This release is cut from `release/2.5.x`, not from `main`.
- `v2.5.2` does not include the #1474 fix; use `v2.5.3` for the owner-card readiness hotfix.
- The release tag includes the metadata stamp plus the #1474 stable hotfix. No installer, model-routing, compose, GPU-detection, or dependency changes were introduced by the stamp itself.
