The operator, reviewing SNMP on #5214: "this system looks incomplete like
there's something missing from it". The one device shown was plugin.yaml's
example (core-switch 192.168.1.1, community public), polled every minute;
devices could only be defined by editing YAML in the image; a failed poll was
logged at DEBUG and stored nowhere, so the page said "waiting for the next
poll" forever; v3 ran as v2c; counters showed as lifetime totals.
- Devices are rows (snmp_devices, migration snmp_001): address, port,
v1/v2c community or a v3 user with auth/priv protocols and keys (secrets
encrypted), presets plus custom readings, an optional host binding, and
the newest poll's outcome. The YAML device list and its example are gone.
- The SNMP page adds, edits and deletes them (admin, audited, with
get_audit_entities so the audit log names and links a device). Readings
come from presets (system uptime, interface traffic by number, UPS-MIB,
Linux net-snmp) and custom "OID name [unit]" lines.
- One GET per device with every OID, devices polled at once. The outcome is
written to the row in words ("No reply from … within 5 s. Check the address
and port, that SNMP is on, and the community"), with readings it lacks.
v1's whole-request error drops that OID and asks again. SNMPv3 signs in
with USM (MD5/SHA-1/SHA-2, DES/3DES/AES).
- Test asks the unsaved form's device for its name, description, uptime and
interfaces by number. It is an admin's explicit action; every page reads
only stored rows (System 178's ruling).
- Each reading has a unit; a counter is stored as a per-second rate (bytes as
bit/s), a reset or wrap skipped. The page, widget and host panel say values
in units and why a device is silent; the device page draws a chart per
reading on a dated axis.
Tests: readings and presets, the form and its secrets, v3 checks, rates,
the poller against a stand-in pysnmp (one GET, v1 retry, timeout wording,
USM), the pages, and an integration test of the poll writing outcomes and
rates on Postgres.

#5255 "SNMP — Devices: status in words and key readings".
- Verdict first: "All N devices answering", "ups: no reply since 14m ago",
"N of M devices not answering", or "N not polled yet".
- Devices that stopped answering come first, then those never polled, then
the rest.
- One header row: Device / Readings / Polled.
- The name is the link; the separate "detail →" is gone.
- The hollow dot is replaced by words: "no data yet", or "no reply since …;
readings are from then".
- Key readings: the first two in config order, gauges ahead of counters.
Units come from the label suffix: _centisecs as a duration, _pct, _dV as
volts, _octets as bytes total.

#5210 "Problems first, with since-time, across every list" (milestone 477),
second batch.
- Host page: an "Alerts on this host" strip first (rules on its agent
series, its containers or its monitors: alert_svc.watches_host); its
monitors problems first with "Down 12m · reason"; Docker above Ansible.
- Uptime page and widget: worst 24h uptime first, then 7d and 30d; hosts
with no uptime yet last.
- Agent panel and fleet widget: last seen as "3m ago", not a clock time.
- SNMP: a device is "Reachable" only while it answered within the last 3
polls; older readings say "No answer" with their age, and every device
says when it was last read (was: reachable whenever any reading existed).
- Traefik: a router missing from 3 scrapes in a row is listed apart as no
longer reported, by when it was last seen, instead of keeping its last
state (a removed router stayed Failing).

The dashboard's host widgets took 18-60 s. Every "latest reading" query
(hosts overview, host-agent fleet, host page, vitals, SNMP, MCP get_host)
searched plugin_metrics for the newest row per metric. Postgres has no skip
scan, so each one read every raw sample in the 7-day window.
- plugin_metric_latest: one row per (source, resource, metric).
record_metrics upserts it in the same transaction, moving forward only and
in sorted key order. Migration 0030 seeds it by stepping the existing index.
- Retention drops a latest row once its sample leaves the raw window, so a
resource that stopped reporting disappears when its history does, as before.
Renames carry it along.
- A quiet host keeps its last values, marked stale. A time-bounded query
would have shown it as missing.
- Vitals sparklines span the 6 h they claim, averaged in SQL to ~120 points,
instead of fetching 6 h raw and drawing the last 120 samples.
- Dashboard and share-view cells: "Loading…" until the first answer; a 20 s
deadline per fetch; "Couldn't load (why)" with Retry now and an automatic
retry for cells that don't poll; "as of HH:MM" in the header, and
"couldn't refresh · as of" when a refresh fails over shown data.

SNMP devices map onto a Steward host's detail page via _devices_for_host,
which previously matched the device's `host` field (the SNMP poll target)
against the Host's address/name — a coincidence of strings that breaks when
the poll target differs from how the Host is recorded.
Add two optional per-device config fields that decouple the binding from the
poll target:
• host_id — exact Steward Host UUID match (the explicit link)
• steward_host — friendly bind by Host name or address (case-insensitive)
An explicit binding is exclusive: a device bound to host A never implicitly
matches host B by a coincidental address. No explicit binding → existing
implicit `host`-string match (fully backward compatible).
host_panel passes host.id and badges explicitly-bound devices. plugin.yaml
documents the new fields. Tests cover explicit id/name, exclusivity, wrong
uuid, and legacy fallback.

SNMP devices are config-defined by IP/hostname, not Steward Host records, so
they had no presence on a host's page. Map them by address and embed a fragment
(mirrors the Docker per-host fragment).
- _devices_for_host(devices_cfg, address, name): case-insensitive match of a
device's configured host to the Steward host's address or name (tolerates
non-dict / host-less entries).
- Route /plugins/snmp/host/<id>: renders the matched device(s) + latest readings,
or nothing when none map (so hosts without SNMP carry no empty card).
- snmp/host_panel.html: per-device card (name · address · reachability) with a
readings grid (K/M scaling) and a History link to the full device page.
- hosts/detail.html embeds it after the Docker fragment, gated on snmp enabled.
- Unit test for the matching helper (by address, by name, no-match, blank).

The fabledscryer->steward rename had only ever reached host_agent. The other
five bundled plugins (http, snmp, traefik, unifi, docker) still imported
`from fabledscryer.*` (package no longer exists) and read FABLEDSCRYER_* env
vars — so every one of them was broken at import since the original rebrand.
CI stayed green only because none are enabled by default and migrations don't
import plugin modules. Now that they version in-tree, complete the rename:
- fabledscryer.* -> steward.* imports across all five plugins
- FABLEDSCRYER_* -> STEWARD_* in plugin migration env.py files
- author/repository/homepage + user-facing 'Fabled Scryer' strings -> Steward
- snmp/scheduler.py: also drop dead `now`/datetime; record_metric from steward
Adds tests/test_no_legacy_names.py — fails if 'scryer'/'roundtable' ever
reappear in shipped code (the drift bit twice; this stops a third time).
Also clears pre-existing ruff lint debt (unused imports, semicolon statements,
mid-file import) surfaced by the new lint lane.

First-party plugins (host_agent, http, snmp, traefik, unifi, docker) are now
tracked under plugins/ and baked into the image, so they version atomically
with core — ending the cross-repo import drift the roundtable->steward rename
exposed. History for these files is preserved in the archived Roundtable-plugins
repo.
Plugin discovery becomes multi-root: PLUGIN_DIR (single) -> PLUGIN_DIRS
(bundled first, then external) + PLUGIN_INSTALL_DIR. Bundled ships in the image;
third-party plugins still mount at runtime into the external root
(STEWARD_PLUGIN_DIR, default /data/plugins) and downloads/installs land there.
Bundled shadows external on a name collision.
- config.py: load_bootstrap returns plugin_dirs + plugin_install_dir
- app.py: iterate PLUGIN_DIRS at the migration + load sites
- migration_runner.py: discover_all_in() unions every plugin root
- plugin_manager.py: resolve_plugin_path() (pure, first-root-wins); load /
install / hot-reload span all roots; installs target the external root
- settings/routes.py: _discover_plugins scans all roots, dedup bundled-first
- Dockerfile: COPY plugins/ ; docker-compose: drop host bind, document external
- tests/test_plugin_dirs.py: resolution, multi-root discovery, bootstrap split
