+#+title: Youdis Task Log 
+#+updated: [2026-03-31 Tue 08:00]
+
+* [X] 1.1.1: stabilize youdis core bot behavior (estimate 3 commits)
+refactor the current `youdis.py` flow so authorization, download execution, and user feedback are correct and predictable without changing the product shape.  keep this narrowly scoped to correctness and maintainability; do not redesign into a queueing platform yet.  preserve archive-first behavior and dm status updates; do not add new infrastructure dependencies and prefer boring explicit state over clever concurrency.
+
+** acceptance criteria
+1. initialize and load `/config/users.json` safely in all cases
+   - create parent dirs before touch/open
+   - ensure `authorized_users` always has a valid default
+   - normalize stored ids to a single type
+2. fix command-path correctness for `/youtube`, `/adduser`, and `/removeuser`
+   - authorized users can successfully invoke downloads
+   - add/remove user commands persist changes correctly
+   - remove broken/incomplete code paths
+3. duplicate prevention relies on archive.txt
+
+** pm notes
+
+** evidence
+- commit: 033d9dd
+- tests: ~python3 -m py_compile ./youdis.py~
+- datetime: [2026-03-31 Tue 13:28]
+
+** notes
+- store Discord user ids as strings in `users.json`
+- duplicate prevention should continue to rely on `archive.txt`, not inferred hook errors
+
+* [ ] 1.1.2: remove global mutable download state and define single-job semantics (estimate 2 commits)
+eliminate shared mutable hook state and make concurrent behavior explicit, even if the initial policy is just "one active job at a time."  don't build a scheduler; ok if simplest outcome is single active job with clear busy message.  cancellation can be coarse if yt-dlp/process boundaries make graceful stop annoying
+
+** acceptance criteria
+1. improve runtime handling for downloads
+   - replace brittle thread/join pattern with a simpler async-safe execution path
+   - catch and report real yt-dlp failures
+   - avoid misleading "already exists" error assumptions
+2. progress reporting is isolated per request
+   - no module-level mutable title state shared across jobs
+   - hooks derive state from request-local context
+3. active-job behavior is explicit
+   - either reject a second request while busy or implement a minimal tracked active job
+   - user-facing response explains current behavior
+4. `/interrupt` is either implemented minimally or downgraded honestly
+   - no fake command implying cancellation works when it does not
+   - command behavior matches implementation
+
+** evidence
+- commit:
+- tests:
+- datetime:
+
+** notes
+- verify slash-command response patterns against the `interactions` library while touching runtime flow
+
+* [ ] 1.1.3: move static yt-dlp behavior into config and shrink python surface area (estimate 2 commits)
+shift stable downloader options into `default-yt-dlp.conf` so the bot code only handles dynamic inputs and orchestration.  optimize for inspectability and low-friction manual ops.  keep output naming durable enough for plex/plain-file use.  avoid duplicating config values across code and conf.
+
+** acceptance criteria
+1. separate static vs dynamic yt-dlp options cleanly
+   - stable defaults live in `default-yt-dlp.conf`
+   - python injects only request-specific/runtime values
+2. preserve archive and output behavior
+   - `archive.txt` remains the duplicate-prevention mechanism
+   - output paths remain stable and browseable
+3. document config ownership
+   - clarify which settings belong in config vs code
+   - make future yt-dlp tuning possible without major python edits
+
+** evidence
+- commit:
+- tests:
+- datetime:
+
+** notes
+
+* [ ] 1.1.4: simplify image/build/update workflow around manual ops (estimate 3 commits)
+reduce repo cruft from the gitea-runner/nightly-update experiment and replace it with explicit manual update/rebuild mechanics.
+
+** acceptance criteria
+1. define a manual update path for yt-dlp and app image lifecycle
+   - document or script manual `git pull`, rebuild, and redeploy
+   - remove or quarantine brittle auto-update assumptions
+2. review and simplify `update-ytdlp.sh`, workflow yaml, and weekly restart artifacts
+   - keep only artifacts that serve the current manual-ops model
+   - delete or mark deprecated anything tied to abandoned automation paths
+3. retain unraid deployment viability
+   - container can still be rebuilt and redeployed cleanly on jeeves
+   - resulting flow is understandable without rereading old ci experiments
+
+- pm note: weekly restart is presumed suspect until proven necessary
+
+** evidence
+- commit:
+- tests:
+- datetime:
+
+** notes
+- do not let runner/workflow complexity dominate a small bot
+- prefer explicit version pinning or manual binary refresh over magical nightlies
+
+* [ ] 1.1.5: clean up packaging/deployment artifacts for unraid consumption (estimate 2 commits)
+make the dockerfile, run script, and unraid-ca template consistent with the refactored app so deployment is less of a ritual ordeal.
+
+** acceptance criteria
+1. align docker/runtime assumptions
+   - paths like `/config` and `/downloads` are consistent across code, scripts, and container metadata
+   - env vars are documented and validated
+2. review deployment artifacts for drift
+   - `dockerfile`, `run-youdis.sh`, and `unraid-ca-template.xml` reflect current behavior
+   - remove stale references and dead assumptions
+3. make fresh deployment understandable
+   - a new deploy on unraid is possible without reconstructing tribal knowledge from old files
+
+- pm note: this is packaging polish after core correctness, not before
+
+** evidence
+- commit:
+- tests:
+- datetime:
+
+** notes
+- keep container surface area small
+- optimize for “future me can redeploy this without cursing past me too hard”
