In `@src/main/java/net/tfminecraft/rpcharacters/focus/FocusData.java`:
- Around line 65-71: Update FocusData’s regeneration logic to accumulate
fractional points for each complete interval using a persisted fractional
remainder, rather than rounding to at least one point per interval. Avoid
narrowing the interval count before multiplication, retain the fraction after
awarding whole points, and clear the remainder when points are capped; advance
lastRegenMs only by complete intervals processed, preserving existing behavior
for any additional partial interval.
In `@src/main/java/net/tfminecraft/rpcharacters/focus/FocusService.java`:
- Around line 152-154: Gate cached-focus access on an active character in
FocusService: update dataFor to return no data for inactive characters, and make
tickRegen and saveAllOnline deactivate and skip players without an active
character before reading loaded. Preserve existing behavior for active players.
In `@src/main/java/net/tfminecraft/rpcharacters/focus/FocusStore.java`:
- Around line 80-84: Update FocusStore.fileFor to reject character IDs
containing either path separator before constructing the file path, preventing
reads or writes outside the focus folder.

Accrue fractional points per complete interval and prevent interval-count overflow.
base_per_hour and extra_per_hour_per_point form the hourlyRate. A short regen_interval_ticks must not force one point per interval. With 100 ticks, the current code awards 720 points per hour for a rate of 10. The int cast can also overflow before multiplication.
Do not replace the interval calculation with floor(elapsed / msPerPoint). That counts an incomplete configured interval. FocusDataTest expects 20 points after two complete one-hour intervals, although the elapsed time includes an additional partial interval.
Add a persisted fractional accumulator to FocusData. For each complete interval, add hourlyRate * intervalMs / 3_600_000 to the accumulator, award its whole-point part, retain its fraction, and advance lastRegenMs by the complete intervals processed. FocusStore serializes FocusData with Gson, so the accumulator will persist with the record.

RPCharacters now owns per-character focus configuration, storage, lifecycle and regeneration. Expose RPCharacters.getFocusService() for Magic/Research and provide /focus restore and /focus reload with rpchar.focus.admin (operator default). Invalid records remain unavailable rather than being replaced with fresh balances; focus reload failure does not skip unrelated character reload steps.
The plugin reads only its own focus.yml and data/focus files. Operators copy the existing server files manually before starting the coordinated dev/main update; there are no automatic imports or version-detection paths. Technical instructions are in Docs. Cached focus must match the active character, and storage rejects path separators in character IDs.
Regeneration cadence, rounding and record format are preserved by this ownership move. CodeRabbit identified existing fractional-rate rounding/overflow behavior; correcting the rate model and adding persisted fractional accrual is deferred to a separate behavior change.
Validation: Maven verify passed 96 tests (baseline 78), covering persistence/corrupt records, character switching, regeneration, service lifecycle, inactive/mismatched character caches, path rejection and admin commands; runtime JAR checks passed. Intended provider API release: RPCharacters 2.1.0.
Coordinated PRs
TLibs 2.1.0 and RPCharacters 2.1.0 are published with verified release artifacts. No server deployment has been performed.
