+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1) Validate existing TASK-109 implementation in working tree against AC #1-#5 (config default-off, activity mapping/transitions, polished visuals, resilient error handling, docs coverage).
+2) Run parallel audit passes (config/docs and runtime/lifecycle) and apply minimal fixes only for confirmed gaps.
+3) Execute focused Discord/config tests, then full gates (`bun run build`, `bun run test:fast`, `bun run docs:build`) and record outcomes.
+4) Capture manual Discord-session verification status/evidence.
+5) Finalize TASK-109 in Backlog with checked AC/DoD, final summary, and status Done (no commit).

 Updated docs and generated config examples with Discord Rich Presence setup/config/troubleshooting guidance.
 
 Validation status: focused config/runtime/discord tests pass and docs build passes. Full `bun run build` currently blocked by pre-existing `src/main.ts` duplicate imports/symbol errors unrelated to TASK-109 scope (existing in working tree).
+
+User validation feedback: Discord activity resumed to Playing but with noticeable delay after pause/resume transitions.
+
+Adjusted default `discordPresence.updateIntervalMs` from `15000` to `3000` to reduce perceived status refresh lag while keeping debounce/duplicate suppression behavior unchanged.
+
+Updated docs/config examples (`docs/configuration.md`, `config.example.jsonc`, `docs/public/config.example.jsonc`) and config default assertions; reran focused tests: `bun test src/config/config.test.ts src/config/resolve/jellyfin.test.ts` and `bun test src/core/services/discord-presence.test.ts` (all pass).

 Setup steps:
 
-1. Create a Discord application at <https://discord.com/developers/applications>.
-2. Open **Rich Presence > Art Assets** and upload image assets referenced by `largeImageKey` / `smallImageKey`.
-3. Copy the application ID into `discordPresence.clientId`.
-4. Set `discordPresence.enabled` to `true` and restart SubMiner.
+1. Set `discordPresence.enabled` to `true`.
+2. Restart SubMiner.
+
+SubMiner uses a fixed official activity card style for all users:
+
+- Details: current media title while playing (fallback: `Mining and crafting (Anki cards)` when idle/disconnected)
+- State: `Playing mm:ss / mm:ss` or `Paused mm:ss / mm:ss` (fallback: `Idle`)
+- Large image key/text: `subminer-logo` / `SubMiner`
+- Small image key/text: `study` / `Sentence Mining`
+- No activity button by default
 
 Troubleshooting:
 
-- If the card does not appear, verify Discord desktop app is running and `clientId` is correct.
+- If the card does not appear, verify Discord desktop app is running.
 - If images do not render, confirm asset keys exactly match uploaded Discord asset names.
 - If Discord is closed/not installed/disconnects, SubMiner continues running and quietly skips presence updates.

+- [2026-02-23T01:10:27Z] assumptions: TASK-109 code/docs edits already present in working tree from prior handoff and should be validated/closed instead of reimplemented.
+- [2026-02-23T01:11:58Z] progress: created closure plan at `docs/plans/2026-02-23-task-109-discord-rich-presence-closure.md`; next record plan in Backlog task and execute validations.
+- [2026-02-23T01:15:39Z] progress: addressed user-reported delayed Playing resume update by reducing `discordPresence.updateIntervalMs` default from 15000 to 3000 and updating docs/examples/tests; focused config + presence tests green.
