Move the flat backend/tests/*.py into domain subfolders so the suite
mirrors the code's concerns:
data/ climate, grading, scoring, grid, places, store
web/ api, content, homepage, views
notifications/ notify, digest, discord (+ dm/interactions/link)
accounts/ api_accounts
core/ metrics, singleton, dashboard
conftest.py stays at the tests/ root, so its sys.path setup and shared
fixtures still apply to every subfolder. The four tests that derive repo
paths from __file__ get their depth bumped one level to match their new
location. Pytest discovers the subfolders recursively; the CI command
(python -m pytest backend/tests) is unchanged.
Claude-Session: https://claude.ai/code/session_01XXxmNFy9cZ6Gh8Y9thZn62
The homepage was a bare tool: a find-bar and an empty panel reading "Find a
location to begin." A visitor arriving from a search result or a shared link
learned nothing about what the product does before deciding to leave.
Rebuild it around the Weekly view, which is untouched:
- Hero with the question as the h1, and a grade card showing a real graded
example — the most unusual city we're currently tracking, either tail. The
card's frame and text slots are server-rendered with reserved heights, so
app.js re-pointing it at the visitor's own place shifts nothing.
- "Unusual right now" strip, CSS scroll-snap, no JS carousel. A cold-tail city
is force-included whenever one qualifies.
- Stance line, how-it-works, explore cards, and 12 city chips linking into the
~1000-page /climate surface.
- Monthly digest form, in the footer of every page.
Serve / from Jinja instead of a static file with placeholder substitution, so
crawlers and no-JS readers get the whole page as real HTML. home.html.j2
extends base.html.j2 and carries app.js's DOM contract over verbatim; the brand
degrades to a <p> so the hero owns the sole h1. frontend/index.html is deleted
rather than left behind the static mount, where it would keep serving indexable
duplicate content.
"Where is it most unusual right now" has no cheap answer at request time —
percentiles live inside zlib-compressed payload blobs with no column to sort on.
So homepage.py sweeps the warm cache and writes data/homepage.json, read by the
template. The sweep is strictly cache-only (climate.load_cached_recent_forecast
is new, the sibling of load_cached_history), so grading ~1000 cities costs zero
upstream requests. It rides the notifier's timer behind an hourly guard rather
than starting a second daemon, and also runs at the tail of warm_cities so a
fresh deploy has a populated feed.
Instrumentation: metrics gains a product-event counter keyed by (event,
referrer domain, UTC day), behind an allowlist and a per-IP rate limit, fed by
POST /api/v2/event. The referrer is taken from the request's own header, never
from the client. The beacon gets its own inbound category that record_inbound
ignores, so reporting an interaction doesn't also count as traffic. The
dashboard grows an events block with per-referrer attribution.
Email is scaffolded but sends nothing yet. mailer.py talks stdlib smtplib to a
local Postfix null client on 127.0.0.1:25 (deploy/provision-mail.sh), so the
choice between direct-to-MX and relaying through a provider stays a Postfix
config change with no code change. The backend defaults to "console", which
logs and sends nothing, so dev and tests exercise the whole signup path safely.
Signups land in pending_digest unconfirmed; collecting the list shouldn't wait
on delivery.
Also adds /privacy, linked from the footer and kept out of the sitemap.
The strip's classes are named unusual-* rather than record-*: .record-card is
already the SEO records page's, and reusing it leaked layout rules onto
/climate/<slug>/records.
The ops dashboard marked subscription-notifier DOWN ~2/3 of the time after the
notifier was gated to a single leader worker. It judged the daemon by whether
its thread was present on whichever worker answered /api/v2/metrics, but only
the leader runs it — so polls landing on the other two workers saw no thread and
reported DOWN for a perfectly healthy notifier. Per-worker thread checks can't
describe a single-leader daemon, and worse, they could no longer distinguish a
real crash from a normal non-leader.
Report it by liveness instead: the notifier stamps a heartbeat (timestamp +
expected interval) into the shared metrics store each loop iteration, including
once at startup so the dashboard shows it up immediately after a restart. Since
the beat lives in the shared SQLite store, any worker's metrics response carries
it, so the dashboard sees the notifier's health whichever worker it polls.
- metrics.py: both stores record/expose heartbeats (SQLite reuses the meta
table, so every worker's beats share one file); snapshot() converts each beat
to a server-computed age so readers needn't reconcile clock skew.
- notify.py: beat at loop start and every wake.
- dashboard.py: judge heartbeat daemons by freshness (up to 2 missed intervals
before DOWN, with beat age shown); neighbor-warmer keeps its per-worker thread
check, which is correct since every worker runs it.
- Tests: heartbeat store/snapshot shape + cross-worker sharing; dashboard
fresh/stale/missing rendering and the unchanged warmer check. 194 passed.

* Serve the app on thermograph.org at root; redirect emigriffith.dev/thermograph
Move Thermograph to its own domain. thermograph.org serves the app at its root,
and emigriffith.dev/thermograph* permanently redirects there (prefix stripped,
so deep links map straight across).
- app.py: BASE now supports an empty root prefix. THERMOGRAPH_BASE=/ (or empty)
yields BASE="" so routes sit at "/", "/calendar", "/api/v2/…" with no double
slashes; the bare-base redirect is skipped and the static mount falls back to
"/". Non-empty values keep the existing "/thermograph" sub-path behavior
unchanged (backward compatible).
- deploy/Caddyfile: add a thermograph.org site block reverse-proxying to the
uvicorn on 127.0.0.1:8137; turn emigriffith.dev's /thermograph handler into a
permanent redirect to thermograph.org.
- deploy/thermograph.env.example: default THERMOGRAPH_BASE=/.
- DEPLOY.md: document the two-domain layout and that deploy.sh does not ship the
Caddyfile or env — those are applied on the VPS by hand.
The frontend already uses base-relative URLs, so it follows the root base with no
changes. Verified both modes locally (root serves /, /calendar, /api/v2/*; the
/thermograph sub-path still redirects bare→slash and 404s at root).
* Add dashboard (#144)
* Auto-submit IndexNow on deploy when the URL set changes (#130)
Hook the production deploy (deploy/deploy.sh) to ping IndexNow after the health
check passes, so new/changed pages reach Bing/DuckDuckGo/Yandex without a manual
run. Best-effort — wrapped so it can never fail a deploy — and it sources
/etc/thermograph.env so its key matches the one the running service serves.
To avoid re-blasting ~14k URLs on every code push, indexnow.py gains a
--if-changed mode gated by a signature of the URL set (persisted to
data/indexnow_state.txt): code-only deploys skip; a deploy that adds or removes a
city submits. `make indexnow` still forces a full submit.
* Add ops metrics endpoint + SSH/Termux dashboard (#131)
Adds observability for the running app, viewable over SSH (e.g. Termux):
- backend/metrics.py: thread-safe, best-effort in-process counters for inbound
requests (per category) and outbound calls (per external source), plus a
phase->source map and snapshot(). Hooked into climate._request (outbound, all
six weather/geocode sources) and the existing revalidate_static middleware
(inbound). Never raises into the request path.
- GET /api/v2/metrics: token-gated JSON of the counters + warm-queue depth +
thread names/uptime/pid. Returns 404 unless a valid THERMOGRAPH_METRICS_TOKEN
is presented or the request is direct loopback with no proxy X-Forwarded-*
header, so ops data is never exposed through Caddy on the public domain.
- scripts/dashboard.py (+ scripts/dash, make dashboard): stdlib-only terminal
dashboard. Reads cache (parquet + SQLite), accounts (users + active
subscriptions), and system resources (/proc + systemd) directly, and pulls
traffic from the metrics endpoint over loopback. Live refresh, --once, --json;
mobile-terminal width. Paths resolve relative to the script so the same tool
works on the LAN dev and prod VPS checkouts.
- Monitoring sections in DEPLOY.md / DEPLOY-DEV.md; unit tests for the counters.
* Dashboard: run under the app venv, not the box's default python3 (#132)
The box's default python3 can be a build without _sqlite3 (pyenv 3.10 here), so
./scripts/dash crashed on import. Prefer the repo's .venv interpreter (the Python
the server itself runs on, which always has sqlite3); fall back to python3/python.
Also make the sqlite3 import in dashboard.py optional so a fallback interpreter
degrades to empty cache/accounts panels instead of crashing, and point the
'make dashboard' target at the wrapper.
* Dashboard: redraw live view in place so it stops scrolling to the bottom (#133)
The live loop did a full clear-and-reprint each refresh; when the output is taller
than the terminal (common on a phone) that scrolls the view to the bottom every tick.
Redraw from the top instead: hide the cursor, clear once, then each frame move to home
and rewrite line-by-line (clear-to-EOL + clear-below), capping the body to the window
height so it never prints more lines than fit and never scrolls. Restore the cursor on
exit; piped (non-TTY) output prints plain frames.
* Dashboard: make the live view a scrollable in-place pager (#134)
The live mode is now an alt-screen pager (like top/less): it shows only the latest
snapshot, you scroll it with swipe/arrows/jk/PgUp-PgDn/g/G, and each refresh replaces
the page in place while keeping your scroll position — nothing gets appended below and
the view is never yanked to the top or bottom. On exit it restores the cursor, leaves
the alternate screen, and resets the terminal mode.
--once still prints a single static snapshot (also used automatically when stdout/stdin
aren't a terminal, e.g. piping); --json unchanged.
* Metrics: don't count the dashboard's own /api/v2/metrics polling (#135)
The ops dashboard polls the metrics endpoint every few seconds; counting those hits
just shows the monitor watching itself and inflates the inbound totals. Skip the
'metrics' category in record_inbound (so it's excluded from inbound_total too), and
hide it in the dashboard's inbound list defensively.
* Dashboard: add a STORAGE section (archive + DB sizes) (#136)
Show on-disk storage: the parquet archives (with history/recent split), the derived
SQLite DB, and the accounts SQLite DB individually, plus a total. Archive bytes are
summed during the existing TTL-cached cache scan; DB sizes include the -wal/-shm
sidecars (WAL holds recent writes, so the base file alone understates the footprint).
Drop the now-redundant 'payload db' line from CACHE.
* Dashboard: show STORAGE sizes in fixed GB (0.01 GB floor) (#137)
The auto-scaling formatter only switched to GB once a value passed 1 GB, so the
archives read as MB and the DBs as KB. Format the STORAGE section in fixed GB with two
decimals and a 0.01 GB floor (so the small databases stay visible instead of rounding
to 0.00). Memory readouts keep the auto-scaling formatter.
* Dashboard: show STORAGE under 50 MB in MB, GB above (#138)
Values below 50 MB now render as MB with one decimal (no KB), so the databases read
naturally (derived 7.7MB, accounts 0.4MB) instead of 0.01GB; 50 MB and up stay in GB
with two decimals. Renames the helper _gb -> _storage_size to match.
* Dashboard: move STORAGE MB->GB cutoff to 500 MB (#139)
Values below 500 MB show in MB (one decimal); 500 MB and up in GB.
* Dashboard: accounts totals only; log client IPs per request (#140)
Dashboard ACCOUNTS section now shows only totals (users, active/total subscriptions,
notifications, push subs) — the per-user and per-subscription lists are gone, and the
dashboard no longer queries that PII at all.
Backend: add a per-request access log (logs/access/access-<date>.jsonl) recording the
client IP (real IP via the left-most X-Forwarded-For hop when proxied behind Caddy,
else the peer address), method, path, status, and category. Static assets and the
dashboard's own metrics polling are skipped. Best-effort, never raises into the request
path — retained for later traffic/IP analysis.
* Dashboard: wrap-aware pager so the header stops scrolling off (#141)
The pager counted one screen row per logical line, but on a narrow phone many lines
wrap to two rows — so a page printed more physical rows than the terminal had, scrolling
the top (title + CACHE header) off-screen with no way to scroll back to it. Measure each
line's wrapped height and fit a page to the real physical-row budget; page/End step by
what's actually visible; read the true tty size (not shutil, which honors stale
COLUMNS/LINES). Status line is clipped to one row.
* Add log storage size to the ops dashboard STORAGE section (#142)
The STORAGE section reported parquet archives and both SQLite DBs but
omitted the logs/ footprint, so the "total" understated real disk use.
Add a recursive _tree_size helper and a "logs" row measuring the whole
logs/ tree (audit + errors + access JSONL plus stray *.log files), broken
out by stream, and fold it into the STORAGE total. Flows through --json
automatically via read_storage.
* Dashboard: show last-10-minute traffic per category (#143)
Add a rolling short-window view alongside the since-start totals. metrics.py
keeps per-minute buckets (epoch-minute -> {key: count}) for inbound categories
and outbound sources, summed over the last 10 minutes on snapshot() and exposed
as inbound_recent / outbound_recent / window_minutes. Cheap and bounded — at most
WINDOW+1 tiny dicts, pruned as minutes roll off; self-polling still excluded.
The dashboard's TRAFFIC section now renders that count as a dim column next to
each row's total (header reads "total · last 10m"); idle sources show "-".
* Add dashboard #2 (#145)
* Auto-submit IndexNow on deploy when the URL set changes (#130)
Hook the production deploy (deploy/deploy.sh) to ping IndexNow after the health
check passes, so new/changed pages reach Bing/DuckDuckGo/Yandex without a manual
run. Best-effort — wrapped so it can never fail a deploy — and it sources
/etc/thermograph.env so its key matches the one the running service serves.
To avoid re-blasting ~14k URLs on every code push, indexnow.py gains a

The dashboard's TRAFFIC section now renders that count as a dim column next to
each row's total (header reads "total · last 10m"); idle sources show "-".
* Run prod on 3 uvicorn workers with a shared metrics store
A single slow upstream weather fetch (cache-miss during an open-meteo/NASA
degradation) blocked the one uvicorn worker and took the whole app down for
~2 min — real users got aborted connections. Give prod concurrency headroom so
one slow request can't freeze the rest.
- deploy/thermograph.service: worker count is env-driven (`--workers ${WORKERS}`,
default 1); prod sets WORKERS=3 in /etc/thermograph.env. Dev's separate
--user unit is untouched (stays single-worker).
- metrics.py: with multiple workers, per-process counters would split the tally
and the ops dashboard (polls one random worker) would see only a fraction.
Add a shared SQLite store selected by THERMOGRAPH_METRICS_DB so every worker
tallies into one place; unset keeps the zero-dependency in-memory store for
dev/tests/single-worker. Public API and snapshot shape unchanged.
- The unit defaults THERMOGRAPH_METRICS_DB and clears it on each (re)start via
ExecStartPre, so bumping WORKERS can never silently fragment the dashboard and
"since start" tallies keep their old meaning.
- Tests: cover the SQLite store — cross-worker aggregation, window roll-off,
and env-based selection. Full suite: 178 passed.
Note: applying to prod also needs the unit reinstalled + WORKERS=3 in
/etc/thermograph.env — deploy.sh only pulls+restarts, it doesn't reinstall the
systemd unit.

On prod (served at root) the dashboard first probes /thermograph/api/v2/metrics before
falling back to root; that 404 was classified as inbound 'other' and shown as an error —
the monitor polluting the traffic it displays. Two fixes: classify any */api/v2/metrics
path as 'metrics' (excluded) whatever prefix it arrives under; and cache the working
metrics URL in the dashboard so it stops re-probing the failing base every refresh.
Add a rolling short-window view alongside the since-start totals. metrics.py
keeps per-minute buckets (epoch-minute -> {key: count}) for inbound categories
and outbound sources, summed over the last 10 minutes on snapshot() and exposed
as inbound_recent / outbound_recent / window_minutes. Cheap and bounded — at most
WINDOW+1 tiny dicts, pruned as minutes roll off; self-polling still excluded.
The dashboard's TRAFFIC section now renders that count as a dim column next to

just shows the monitor watching itself and inflates the inbound totals. Skip the
