fix(analysis): exclude suspect runs from every average, not just attenuation
Review finding, and it was right. The PR claimed that runs with impossible readings were "excluded from the averages". That was only true of the attenuation average. Run 12's bad final gravity was still poisoning three other statistics: - **Brew time** - its 56 days were folded into the average, making a typical brew look like 13.7 days when it is 10.9. - **Time to 1.010** - its 56 days did the same to that figure (8.4d). - **The history page's ABV** - an 18.64% ABV, which made run 12 the "strongest" beer in the history and pulled the average up. - **The fermentation curve** - its curve plunges from 1.042 to 0.900, which dragged the median line down and stretched the min-max envelope to cover a gravity below water. One bad reading was reaching four different statistics. What changed ------------ - The suspect runs are computed once and excluded from every aggregate: the attenuation, brew-time and time-to-1.010 averages, the fastest and slowest brews, the history page's ABV average, and its strongest and lightest. - `/api/runs` now carries a `suspect` flag, and the charts skip the flagged runs - the attenuation chart and the fermentation curve. - The suspect run stays in the table, with a "not counted" chip and a tinted row, so it can be corrected. It is excluded from the figures, not hidden. The card header says "16 brews (15 counted)" and the prose says how many brews the figures are based on. Tests ----- 133 (up from 127). New coverage: the suspect run is excluded from the brew time and time-to-1.010 averages, it is still listed for review, it is flagged in the API, it is not the strongest brew in the history, and the charts filter it out. The `logged_in` fixture moved to conftest.py, where both test modules can use it. |

feat(analysis): attenuation, fermentation curves and brew timings
Adds the analysis page the old app never had: how consistently the brews
ferment, and how long each one takes.
What it shows
-------------
- **Attenuation by brew** - what fraction of the original gravity was
fermented away, for every finished brew.
- **Fermentation curves** - the typical shape of a fermentation, drawn as a
median curve with the min-max envelope behind it. Plotting every brew
individually gave 16 near-identical lines and an unreadable legend.
- **Every finished brew** - OG, FG, ABV, attenuation, days in the fermenter,
days to reach 1.010, and the finish date.
- **Readings that need a second look** - readings outside the plausible
hydrometer range.
- Headline figures: average attenuation and its spread, average brew time,
average time to 1.010.
Data quality
------------
One live run (run 12) has a final gravity of 900, which worked out as 338%
attenuation and dragged the average to 103.2%. That is not a real result,
so:
- Attenuation is rejected when the final gravity is not physically possible
for the original gravity.
- Runs that fail that check are EXCLUDED from the averages rather than
silently distorting them, and are listed on the page as needing review.
- The average now reads 87.5% +/- 7.4 percentage points across 16 brews.
Chart bugs found while building this
------------------------------------
- **The gravity charts had their y axis reversed.** With `reverse: true`
the high reading sits at the BOTTOM, so the fermentation curve climbed
left to right - it read as gravity *rising* as the beer fermented. A
brewer reads a fermentation as a descending line. The point-scale run
chart on the run detail page had the same bug. Both are fixed.
- **The curve chart's x axis was treated as categorical.** The x values are
numeric (0-100), and Chart.js defaults a line chart's x axis to
category, which collapsed every point onto index 0 and rendered the
curve as a sliver at the origin. The axis is now explicitly linear.
- **The curve was interpolated by exact key lookup**, so it only worked when
every brew happened to be read at the same progress points. It now
interpolates between a brew's actual readings, and the curve carries 21
points across the full range.
- **Long beer names were clipped** at the left edge of the attenuation
chart ("...x crying out loud"). Names are trimmed to 18 characters with
an ellipsis; the tooltip and the table carry the full name.
Tests
-----
127 (up from 105). The two chart regressions are covered by reading
`charts.js` and asserting the gravity axis is not reversed and that long
names are trimmed - these are exactly the kind of change that silently
reverts, and they are invisible to a screenshot test.

fix: build the image on Python 3.14, and fix the review findings
The image build failed on master:
ERROR: Ignored the following versions that require a different python
version: 4.19.0 Requires-Python >=3.11
ERROR: Could not find a version that satisfies the requirement
pymongo==4.19.0
The base image was `python:3.10` but the pinned pymongo 4.19 needs Python
>= 3.11. The image is now `python:3.14-slim` — the current stable release,
so it is not carrying the CVEs fixed in 3.11, 3.12 and 3.13.
All the runtime dependencies ship a cp314 wheel (pymongo included), so no
compiler toolchain is needed. The old apt-get line installed
libsasl2-dev, python-dev-is-python3, libldap2-dev and libssl-dev for
packages that are no longer in the dependency list, so it is gone and the
image is smaller.
The build now asserts the interpreter version, so a base image change that
breaks the pinned requirements fails the build with a clear message rather
than a pip resolution error.
Review findings, all from the independent review of this PR
------------------------------------------------------------
- Mongo indexes: the run metadata is always looked up by `beer_run_id` and
the readings by `(beer_run_id, date)`. Both are now indexed.
- Content-Security-Policy: the app serves only its own vendored assets, so
a strict `default-src 'self'` policy is enforceable. Adding it required
removing the inline `style=` attributes from the templates (they became
`.mb-lg` / `.mt-lg` utility classes) and the one inline `<script> (the run
id now travels as a `data-run-id` attribute). A test asserts no template
has either.
- Job timeouts: the `test` and `build` jobs now have `timeout-minutes`, so
a wedged build stops occupying a runner.
- OG range: raised from 1300 to 1500 points, so a strong specialty brew
(a 1.150 wort is real) can be recorded.
Bugs found and fixed along the way
----------------------------------
- An unfinished run reported a *measured* ABV. `abv_percent()` now returns
None for a run that is still in the fermenter — its figure is a projection,
not a measurement. This was showing the two active runs in the "alcohol by
brew" chart as if they were finished.
- The `/api/runs` endpoints the charts fetch from did not exist, so every
chart was silently empty. They are back, with tests.
- The "brews over time" chart left out the months with no brews, which
spaced the busy months evenly and made the chart read as continuous
activity. The quiet months are now included with a zero.
- The run-detail chart was dropped when PR 1 was scoped down, leaving dead
code behind. It is restored.
Tests: 105 (up from 91).

feat(active): add the active beers page, run metadata and tap numbers
Adds the pages that were missing: an "Active Beers" view of what is in the fermenter right now, and the per-run metadata (canonical name, tap number, original gravity, brew notes) that could not be derived from the readings. Why the metadata is needed -------------------------- The `beer_data` collection stores a beer name on *each reading*, and that name drifts within a run - run 4 was entered as "Necatron-Christmas Beer", then "Nocturna the Christmas beer", then "Nocturna Christmas beer". There was nowhere to record a tap number, a confirmed original gravity, or a note about the brew. The new `beer_runs` collection holds one document per run with exactly those details. It starts empty; `scripts/backfill_run_metadata.py` populates it from the existing readings. The script is idempotent, only ever inserts into `beer_runs`, never touches `beer_data`, and never overwrites a name you have already set by hand. The active beers page --------------------- A card per brew that is still in the fermenter, showing the tap number, the current gravity, the projected alcohol, how many days it has been brewing, a sparkline of the gravity so far, and the latest comment on a reading. A run with only one reading and no recorded original gravity has no reliable estimate, so the alcohol figure shows a dash rather than a misleading number - record the OG or take a second reading and it appears. The same applies to the existing reads, where the legacy app's assumed OG of 1012 produced *negative* alcohol for a perfectly normal OG. Also adds the history page: alcohol by brew, brews per month, every run in a table, a comparison of the standard ABV formula against the legacy one, and a list of readings that fall outside the plausible hydrometer range. Changes to the existing pages ----------------------------- - The brew-process page and the run detail page now show the canonical run name and the latest comment, and the run detail page lets you edit the metadata inline. - Gravity is displayed as a decimal reading (1.039) with the point scale beneath it (39 points), which is the way a brewer reads it. Labelling the stored `1039` as "1039 points" would have been wrong. - A run's display name now prefers the name on its *final* reading - the one written when the brew was finished, so the name the operator settled on - falling back to the most-used name. - `upsert_run_metadata` now clears a field when it is passed as `None`, so a name or tap number can be deleted. `upsert_run_metadata_partial` is the non-clearing variant, used by the backfill. Bugs found and fixed along the way ---------------------------------- - The chart script was included both in the base template and again by each page, so every chart was drawn twice. A test now asserts it is loaded exactly once per page. - The chart library was never referenced by the base template, so all charts were silently dead. That was fixed in the previous PR. Tests ----- 91 (up from 74). New coverage: the active page contents, the tap number, the projected alcohol, the "needs 2nd reading" case, metadata saving and clearing, the stored name overriding the drifting reading name, the next free tap number, the partial-update semantics, the history page, the outlier list, and the point-scale formatting. Data safety ----------- `beer_data` is untouched by this change. The backfill script only inserts into `beer_runs` and skips any run whose name has already been set by hand. |
