# Zero-OS Builder – Persistent TODO

This canonical checklist is the single source of truth for ongoing work. It mirrors the live task tracker but is versioned in-repo for review and PRs. Jump-points reference exact functions and files for quick triage.

## High-level

- [x] Regenerate repository function index: [scripts/functionlist.md](../scripts/functionlist.md)
- [x] Refresh NOTES with jump-points and roadmap: [docs/NOTES.md](NOTES.md)
- [x] Extend RFS design with RESP/DB-style backend: [docs/rfs-flists.md](rfs-flists.md)
- [x] Make Rust components Git fetch non-destructive: [bash.components_download_git()](../scripts/lib/components.sh:72)
- [ ] Update zinit config for "zosception" workflow: [config/zinit/](../config/zinit/)
- [ ] Add zosstorage to the initramfs (package/build/install + zinit unit)
- [ ] Validate via minimal rebuild and boot tests; refine depmod/udev docs
- [ ] Commit and push documentation and configuration updates (post-zosception/zosstorage)

## Zosception (zinit service graph and ordering)

- [ ] Define service graph changes and ordering constraints
  - Reference current triggers:
    - Early coldplug: [config/zinit/udev-trigger.yaml](../config/zinit/udev-trigger.yaml)
    - Network readiness: [config/zinit/network.yaml](../config/zinit/network.yaml)
    - Post-mount coldplug: [config/zinit/udev-rfs.yaml](../config/zinit/udev-rfs.yaml)
- [ ] Add/update units under [config/zinit/](../config/zinit/) with proper after/needs/wants
- [ ] Validate with stage runner and logs
  - Stage runner: [bash.stage_run()](../scripts/lib/stages.sh:99)
  - Main flow: [bash.main_build_process()](../scripts/build.sh:214)

## ZOS Storage in initramfs

- [ ] Decide delivery mechanism:
  - [ ] APK via [config/packages.list](../config/packages.list)
  - [ ] Source build via [bash.components_parse_sources_conf()](../scripts/lib/components.sh:13) with a new build function
- [ ] Copy/install into initramfs
  - Components copy: [bash.initramfs_copy_components()](../scripts/lib/initramfs.sh:102)
  - Zinit setup: [bash.initramfs_setup_zinit()](../scripts/lib/initramfs.sh:13)
- [ ] Create zinit unit(s) for zosstorage startup and ordering
  - Place after network and before RFS if it provides storage used by rfs
- [ ] Add smoke command to confirm presence in image (e.g., which/--version) during [bash.initramfs_validate()](../scripts/lib/initramfs.sh:820)

## RFS backends — implementation follow-up (beyond design)

- [ ] RESP uploader shim for packers (non-breaking)
  - Packers entrypoints: [scripts/rfs/pack-modules.sh](../scripts/rfs/pack-modules.sh), [scripts/rfs/pack-firmware.sh](../scripts/rfs/pack-firmware.sh)
  - Config loader: [bash.rfs_common_load_rfs_s3_config()](../scripts/rfs/common.sh:82) → extend to parse RESP_* (non-breaking)
  - Store URI builder (S3 exists): [bash.rfs_common_build_s3_store_uri()](../scripts/rfs/common.sh:137)
  - Manifest patching remains:
    - Stores table: [bash.rfs_common_patch_flist_stores()](../scripts/rfs/common.sh:385)
    - route.url: [bash.rfs_common_patch_flist_route_url()](../scripts/rfs/common.sh:494)
- [ ] Connectivity checks and retries for RESP path
- [ ] Local cache for pack-time (optional)

## Validation and boot tests

- [ ] Minimal rebuild after zinit/units/edit
  - Helper: [scripts/rebuild-after-zinit.sh](../scripts/rebuild-after-zinit.sh)
- [ ] Validate contents before CPIO
  - Create: [bash.initramfs_create_cpio()](../scripts/lib/initramfs.sh:691)
  - Validate: [bash.initramfs_validate()](../scripts/lib/initramfs.sh:820)
- [ ] QEMU / cloud-hypervisor smoke tests
  - Test suite: [bash.testing_run_all()](../scripts/lib/testing.sh:299)
- [ ] Kernel embed path and versioning sanity
  - Embed config: [bash.kernel_modify_config_for_initramfs()](../scripts/lib/kernel.sh:130)
  - Full version logic: [bash.kernel_get_full_version()](../scripts/lib/kernel.sh:14)

## Operational conventions (keep)

- [ ] Diagnostics-first changes; add logs before fixes
- [ ] Absolute path normalization respected
  - Normalization: [scripts/lib/common.sh](../scripts/lib/common.sh:244)
