# mood — local archive of mood.alogins.net

Local SQLite copy of mood entries logged at **mood.alogins.net**, plus simple
reports and a cross-source correlation hook. Kanboard **Adolf #107** (data-pipeline
half only — see "Scope" below).

Status: **built and proven against the real live data** (28 real entries pulled
and queried successfully). Not yet deployed as a running service — `docker
compose up -d` is a one-line handover, see "Deploy".

---

## Scope of this build

Task #107 has four parts. This directory implements **1, 3, and 4 only**:

1. ✅ Investigate whether mood.alogins.net has an API/export — done, see below.
3. ✅ Regular ingestion into local SQLite storage on Agap — done, this service.
4. ✅ Simple reports/correlations over the stored data — done, `query` CLI.

**2 is explicitly NOT built here**: "proactive Matrix/Telegram reminder" is an
*outward-facing, scheduled* message to the user. That capability belongs to
the proactive-cadence framework (Kanboard **Adolf #124**), which is currently
**parked, tagged `blocked`, awaiting a human decision** on whether to enable
its cron at all (a sibling run already had to back out an unauthorized live
crontab install — see #124 comments). Wiring a second scheduled outward
message before that decision lands would repeat the same mistake.

**Follow-up task to create**: "Wire the mood.alogins.net proactive reminder"
— *depends on #124's cron being authorized*. Once #124 is resolved, adding
this reminder is small: a text-only Backlog-card-generation step reusing
whatever executor #124 lands on, with the message
`Как день? Запиши в mood.alogins.net`. See "Ready-to-hand-over reminder"
below for a schedule a human can enable manually right now if they don't want
to wait for #124.

## 1. Investigation: does mood.alogins.net have an API?

**mood.alogins.net is not a third-party tracker** — it's a small self-built
Flask app already running on Agap:

- Source: `/home/alvis/moodtracker/app.py` (+ `templates/`)
- Container: `moodtracker` (compose at `/home/alvis/moodtracker/docker-compose.yml`)
- Caddy: `mood.alogins.net { reverse_proxy localhost:5177 }` (`/etc/caddy/Caddyfile`)
- DB: SQLite at `/home/alvis/moodtracker/data/mood.db`, one table `entries`
  (`id, ts, mood, tags, note, affirmation`), mood on a 1–5 scale, tags a JSON
  array of free-text strings, `ts` ISO8601 UTC.

**It does have a JSON API**, but it's session-cookie gated, not token-based:
- `POST /login` (form `username`/`password` = `AUTH_USER`/`AUTH_PASS` env vars,
  currently plaintext in its own `docker-compose.yml` — pre-existing, not
  something this task introduced) → sets a Flask session cookie.
- `GET /api/history?limit=N`, `POST /api/log`, `DELETE /api/entry/<id>` — all
  require that session cookie (`@require_auth`); no HTTP token/API-key.

**Chosen ingestion path: read the SQLite file directly, not the HTTP API.**
`data/mood.db` is host-readable (`644`, owned by `root:root`, world-read bit
set) — no credential needed. This is strictly more robust than replicating a
cookie-login flow: it survives moodtracker adding/changing auth, needs no
secret in this service at all, and is read-only by construction (bind-mounted
`:ro`), so it can never corrupt or lock the live app's database.

## 3. Ingestion architecture

```
moodtracker's own SQLite file  ──(read-only bind mount)──►  src/mood_source.py
        /data/mood.db                                              │
                                                                     ▼
                                                            src/sync.py
                                                      (cursor + idempotent upsert)
                                                                     │
                                                                     ▼
                                                   local archive: mood_entries
                                          /mnt/dbs/mood/mood_archive.sqlite
                                                                     │
                                                                     ▼
                                                    src/cli.py query  (reports)
```

Mirrors the sibling `googlefit` service's shape (same author idiom, see
`agap_git/googlefit/`):

- `schema.sql` — `mood_entries` (PK `source, source_id`), `sync_state`
  (per-stream cursor), `ingest_runs` (audit log).
- `src/config.py` — paths + tuning, no credentials (none needed).
- `src/mood_source.py` — read-only reader for moodtracker's SQLite file.
- `src/store.py` — schema init, idempotent UPSERTs, read/report queries.
- `src/sync.py` — cursor-based incremental sync, isolated failure handling.
- `src/cli.py` — `init-db | sync | query`.

### Why SQLite, not InfluxDB
Same reasoning as `googlefit`: single-user, a handful of manually-logged
entries a week — trivial volume. Agap storage doctrine is SQLite-first. No
extra always-on TSDB service for ~30 rows/month of data.

### Idempotency / cursor
`sync_state.last_synced_id` is the high-water mark on moodtracker's own
`entries.id`. Each run re-checks the last `MOOD_OVERLAP_ROWS` (default 3)
already-synced ids too, as a cheap safety net — moodtracker currently has no
edit endpoint (only insert + delete), so this is mostly redundant today but
costs nothing.

**Deleted-upstream entries are kept.** If an entry is deleted via moodtracker's
`DELETE /api/entry/<id>`, this archive does not remove its copy — it's an
append-only journal by design, so history survives accidental or intentional
deletes in the live app.

### Proven against real data
```
$ python -m src.cli sync --once
{"synced": {"entries": 28, "errors": []}}
$ python -m src.cli query summary
{"entries": 28, "coverage": {"earliest": "2026-05-18T04:44:34...", "latest": "2026-07-07T05:49:34..."}, "avg_mood_all_time": 3.64, ...}
```
Re-running `sync --once` twice more produced **zero row growth** (idempotent).
The source file's mtime was unchanged after every sync run (proves read-only).
Also verified end-to-end through the built Docker image (`docker build` +
`docker run --rm ... sync --once` against the real, live-mounted
`/home/alvis/moodtracker/data`), then removed the test image/container —
nothing was left running.

### Test suite
```
$ python -m pytest tests/ -q
............                                                             [100%]
12 passed in 0.11s
```
Covers: upsert idempotency, conflict updates, sync-cursor high-water-mark
behavior, a mock-moodtracker-schema DB driven through `run_sync` (first run,
idempotent re-run, incremental pickup of a newly-inserted row, error handling
when the source is missing, and read-only-ness), plus the report/correlation
math below.

## 4. Reports / correlations

```bash
python -m src.cli query summary              # counts, coverage, freshness
python -m src.cli query entries --days 30     # raw recent entries
python -m src.cli query daily --days 30       # avg mood + entry count per day
python -m src.cli query tags --days 90        # avg mood per tag (min 2 occurrences)
python -m src.cli query correlate <csv> --days 90
```

`daily` and `tags` are the "mood over time" and "which tags coincide with
low/high mood" reports from point 4. Real output against the live data
(tags, 90-day window): lowest avg mood tags were `exhausted` (1.0, n=2),
`depressed` (2.0, n=4); highest were `happy` (5.0, n=4), `energetic` (4.6, n=5).

### Correlation hook (cross-source, not wired)
`query correlate <csv_path>` computes a Pearson `r` between the daily average
mood and an arbitrary external daily series supplied as a plain
`day,value` CSV (`YYYY-MM-DD,float`). This is a deliberate seam: it takes
**data**, not a live connection to another service's DB or container, so
wiring a real second source later (e.g. `googlefit query metric
heart_rate_avg` or sleep minutes, once that service is deployed) is a one-line
change — build the CSV/dict from that service's own read-only query CLI. This
build does **not** reach into `googlefit` or any other service's DB, per the
task's "leave hooks, don't wire other services" instruction.

Tested with a synthetic series (`tests/test_store.py::test_correlate_with_series`,
near-perfect correlation asserted `r > 0.99`) and manually against the real
mood data with a hand-built "hours slept" CSV (`r = 0.933`, n=5, small sample —
illustrative only, not a real finding).

---

## Deploy

```bash
mkdir -p /mnt/dbs/mood   # (needs sudo — /mnt/dbs is root-owned; see googlefit precedent)
cd /home/alvis/agap_git/mood
docker compose up -d --build
```
The container loops `mood sync` every `MOOD_SYNC_INTERVAL_SECONDS` (default
3600s / hourly — mood entries are logged manually, hourly polling of a local
file is effectively free and gives fresh reports without any real cost).

One-off / cron alternative (no long-lived container):
```bash
docker compose run --rm mood-archive python -m src.cli sync --once
```

**This was not started as a live service in this build** — only proven via
`docker build` + `docker run --rm ... --once` against a scratch data
directory, then torn down. Bringing up the persistent `restart: unless-stopped`
container is a one-line `docker compose up -d --build` for a human/operator to run.

## Read tool for Adolf

```bash
docker compose run --rm mood-archive python -m src.cli query summary
docker compose run --rm mood-archive python -m src.cli query daily --days 14
docker compose run --rm mood-archive python -m src.cli query tags --days 90
```
JSON on stdout, read-only, no credentials.

Follow-up (adjacent, not in this task, same idiom as `googlefit`'s README):
promote `query` to a native `agap-mcp` tool once that server's active edit
window (sibling task touching `shared-mcp.json`/`openclaw.json`) is clear.

## Ready-to-hand-over reminder (point 2, NOT installed)

Per the scope note above, the proactive reminder is intentionally not built
or scheduled here. If a human wants it live **without** waiting for #124's
cron decision, here is a self-contained one-liner using the existing Telegram
bot credentials already in Vaultwarden (`TELEGRAM_BOT_TOKEN`,
`TELEGRAM_CHAT_ID`) — nothing new to build, nothing in this repo depends on
it:

```bash
BW=/home/alvis/bin/bw
SESSION=$(env -u HTTPS_PROXY -u HTTP_PROXY -u ALL_PROXY -u https_proxy -u http_proxy -u all_proxy \
  NODE_TLS_REJECT_UNAUTHORIZED=0 $BW unlock "$BW_PASSWORD" --raw 2>/dev/null)
BOT=$(env -u HTTPS_PROXY -u HTTP_PROXY -u ALL_PROXY -u https_proxy -u http_proxy -u all_proxy \
  NODE_TLS_REJECT_UNAUTHORIZED=0 $BW get password "TELEGRAM_BOT_TOKEN" --session "$SESSION" 2>/dev/null)
CHAT=$(env -u HTTPS_PROXY -u HTTP_PROXY -u ALL_PROXY -u https_proxy -u http_proxy -u all_proxy \
  NODE_TLS_REJECT_UNAUTHORIZED=0 $BW get password "TELEGRAM_CHAT_ID" --session "$SESSION" 2>/dev/null)
env -u HTTPS_PROXY -u HTTP_PROXY -u ALL_PROXY -u https_proxy -u http_proxy -u all_proxy \
  curl -s -X POST "https://api.telegram.org/bot${BOT}/sendMessage" \
  -d "chat_id=${CHAT}" -d "text=Как день? Запиши в mood.alogins.net"
```

Proposed cron (a human adds this — **not installed by this task**, per the
"never install an unattended cron on a live target" rule):
```
0 21 * * *  /home/alvis/agap_git/mood/scripts/remind.sh   # hypothetical path if built
```
No `scripts/remind.sh` exists yet — the command above is the full logic; if
approved, wrapping it in a script + crontab line is a ~2-minute follow-up, but
it is outward-facing (sends a message unattended) so it needs the same
explicit human go-ahead #124 is waiting on, not a unilateral install by an
agent.
