Closes the remaining tractable items from the carry-forward queue.
1. Drop-root scaffold for the backend container (P2 mitigation)
`backend/Dockerfile` adds non-root `app` user (uid 1001) + `docker`
group (gid via `DOCKER_GID` build arg, default 999). `BACKEND_USER`
build arg defaults to `root` so existing deployments keep working;
set it to `app` plus `DOCKER_GID=$(getent group docker | cut -d: -f3)`
to flip the runtime non-root. `dashboard/DEPLOYMENT.md` gets a new
"Running non-root" section with the exact `chgrp`/`chmod` recipe
for the bind-mounted log files (the host-side prep that pairs with
the build flip). DEPLOYMENT.md mitigation roadmap updated.
2. Phase 6 trend cards
`lib/hermes-ops-history.ts` keeps the last 24 ops snapshots in
localStorage (de-duped on `generatedAt`, schema-guarded on read,
degrades silently on quota exceeded). Three trend cards in the
ops panel:
- Warning-volume sparkline + current count
- Healthy-instance count sparkline (X/2)
- Per-instance "minutes since last backup commit" with a 30m
stale threshold
SVG polyline sparklines, no chart library — `<svg viewBox="0 0
100 100" preserveAspectRatio="none">` with `vector-effect:
non-scaling-stroke` so the line stays 2px regardless of the
parent's width.
3. Phase 6 theme toggle
`components/theme-toggle.tsx` Sun/Moon button mounted in the
Hermes layout next to the instance switcher. Persists in
localStorage `bytelyst.theme.v1`. The design system already
defined `[data-theme="light"]` overrides in `styles/tokens.css`;
the toggle just sets the attribute. FOUC-prevention inline script
in the root layout reads the same key BEFORE React hydrates so
the first paint matches the user's last choice.
4. Phase 3 partial close: Agents pane → telemetry inventory
`/hermes/agents` now renders a "Memory & Skills inventory (live)"
SectionCard backed by the Phase 3 telemetry endpoint per instance
— `hermes memory list` and `hermes skills list` rendered with
per-section probe-status badges (`up`/`unknown`), item counts,
and the first N entries each. Agent **health** statuses (latency,
failure rate, last-success/failure) stay seed-data — observability
for those needs a separate ingestion contract that the telemetry
endpoint doesn't provide today.
5. Phase 0 reconfirmation
Roadmap Phase 0 ticked with explicit verification notes for each
guardrail (no public listener, manual approvals, secret hygiene,
Caddy review). Remains "must hold throughout" — the ticks reflect
today's verified state, not single-checkbox completion.
Verified: backend typecheck ✅, 74/74 backend unit tests ✅, web
typecheck ✅, 7/7 E2E ✅, lint 0 errors, build green, coverage gate
≥95% lines on every gated file.
