importEvents inserted every event in one unguarded loop, so a single row the provider refused — it throws on a malformed RRULE straight out of insert — aborted the batch and left the user with "couldn't read this file" and nothing imported. Each event is now isolated and rejects are counted into IcsImportSummary.failed and shown. sanitizeRrule drops empty and malformed rule parts before the write. Alongside that, several things a foreign file carries that we dropped: VTODO components (silently lost, now imported as events), EXDATE, the CATEGORIES calendar name, and colours — X-FOSSIFY-EVENT-COLOR / COLOR / the category colour plus the X-SMT-* legacy spellings, snapped in Oklab to the nearest key a palette account publishes since those reject a raw EVENT_COLOR. Two correctness fixes on our side: an all-day event may no longer end at or before it starts (the provider expands a zero-length series into no instances, so it just disappears), and imported all-day reminders now go through the same encoding as hand-created ones instead of firing at UTC midnight. A VALARM trigger pointing after the start is read as a time of day rather than clamped to zero. Note for later: their all-day DTEND is RFC-correct — endTS anchors at noon of the last day and the exporter's +12h rounds it to the following midnight. Do not "fix" it by sniffing PRODID; the holiday files bundled in Fossify are conformant and name Fossify in theirs. One is kept as a fixture. Refs #225

Where to look for what:
| Document | What it is |
|---|---|
../CONTRIBUTING.md |
How to contribute: issue-first workflow, which branch to target, translations, the rules a change is reviewed against |
BUILDING.md |
Building from source: submodule, JDK/SDK requirements, Gradle tasks, what CI runs |
ARCHITECTURE.md |
Orientation tour: principles, layers, navigation, recurring-write / conflict / reminder pipelines, testing |
RELEASING.md |
Release process: versioning, the merge-driven pipeline, the two-forge split, secrets, key custody |
../CHANGELOG.md |
Release history (Keep a Changelog, SemVer) |
| Issues + milestones | The roadmap. What's planned, in progress, and shipped — a milestone maps to its release/vX.Y.Z branch |
../.planning/PROJECT.md |
What the project is: core value, stack + version pins, constraints, naming, forge/release infrastructure |
design/ |
Per-feature design notes kept for features whose provider behaviour is worth recording |
../fastlane/metadata/android/ |
Store metadata (single source of truth): descriptions, title, icon, screenshots (DE + EN). Harvested directly by the official F-Droid repo; transformed into the self-hosted repo layout at release time by ../scripts/fastlane_to_fdroid_localized.sh |
../fdroid-metadata/ |
App-level F-Droid control file (*.yml: Categories, License, links) for the self-hosted repo's fdroid update |
fdroid-official/ |
Recipe + notes for publishing to the official F-Droid repo (reproducible build + developer-signed binary) |
Conventions: planning lives in the issue tracker, not in this repository. The
.planning/ files that predated it (a roadmap, a development-state snapshot, and
a per-milestone requirement checklist) are gone — issues and milestones say the
same thing without going stale. PROJECT.md is what remains, and it describes
the project rather than its plan.
ARCHITECTURE.md is the authoritative orientation tour: it is updated with the
code, and is the right place for a lesson learned about the calendar provider.
