# Project journal

Append-only, newest first. **Entries are never edited** — the value of this file is
that it records what was believed at the time, including the parts that turned out
wrong. Where things stand *today* is in `STATUS.md`, which is generated.

Four lines per entry. The analysis belongs in the issue or the decision record; this
file carries the reasoning and the pointers.

- **Why** — the driver. The one line git cannot reconstruct later.
- **Obligates** — issues this change created elsewhere. Numbers, not prose.
- **Refs** — commits, issues, decision records.

## 2026-09-30 · repo · moved out of Nextcloud; code syncs only through Gitea

**Why:** Nextcloud was syncing this repo's `.git`, which risks conflict copies inside
it and stalls the client's cold scan across dozens of repos. Nothing untracked is
data, so nothing is linked (`--no-data`); the move changed no test result (1,101
pass, 2 skip before and after).
**Obligates:** #73, #74
**Refs:** 4bedf85 (ci/apt-https pushed to clear the move's preflight), 63b421a

## 2026-09-09 · ci · Linux R-CMD-check legs unblocked (recorded 2026-09-30)

**Why:** GitHub's ubuntu-latest image carries a google-chrome apt source that
intermittently fails its own hash check, and setup-r's `apt-get update` died on it for
every R version; the source is now found by URL and removed, and the step fails
loudly if it survives.
**Obligates:** (none)
**Refs:** d83301b, d1165a5

## 2026-09-09 · model · #36 coverage counter finished, two bugs caught before merge

**Why:** the drafted n_units_collected fix (uncommitted) derived its candidate
cohort from category-filtered results instead of the caller's full expected
cohort, and hardcoded a view name absent below schema_version 5 -- both
silent on the fixture, both would have shipped without an independent review
pass before merge.
**Obligates:** #72
**Refs:** #36, b41d5ee, PR#71

## 2026-09-09 · model · #33/#34 split into independently-tested commits

**Why:** #33's own branch had its tests sitting uncommitted, and quietly bundled
a behavior change (#34) into what its commit message called a pure refactor;
splitting them let each pass CI with its own tests instead of merging on a
false "tests pass" claim.
**Obligates:** (none)
