@@ -1615,3 +1615,34 @@ Current assessment:
- Phase 5.1 is now satisfied on the current FreeBSD prototype track
- the key boundary has shifted from “the checkout still crashes immediately” to “the checkout runs, and can now be used as the basis for real derivation/store experiments”
- the next step is to prove that a real derivation can be emitted against `/frx/store` from the now-runnable checkout
## 2026-04-01 — Phase 5.2 completed: real derivation generation validated against `/frx/store`
Completed work:
- added a runnable derivation-generation harness:
- `tests/guix/run-phase5-derivation-generation.sh`
- wrote the Phase 5.2 report:
- `docs/reports/phase5-derivation-generation-freebsd.md`
- ran the derivation-generation harness successfully and captured metadata under:
- `/tmp/phase5-derivation-metadata.txt`
Important findings:
- the now-runnable checkout can successfully use a real daemon/store connection on FreeBSD to lower a package through:
- `package->bag`
- `bag->derivation`
- the emitted derivation is a real `/frx/store` derivation path rather than an ad hoc placeholder or shell metadata artifact
- the validation used a deliberately minimal custom package with a custom low-level build system so that this subphase isolates the real lowering/store boundary without being dominated by still-unresolved upstream bootstrap assumptions for full native FreeBSD package graphs
- observed metadata confirmed:
- `bag_name=phase5-freebsd-lowering-0`
- `bag_host_inputs=("source")`
- `drv_path=/frx/store/...-phase5-freebsd-lowering-0.drv`
- `out_path=/frx/store/...-phase5-freebsd-lowering-0`
- this means the key architectural step is now real and no longer hypothetical:
- a package object in the checkout can be lowered to a real derivation targeting `/frx/store` on FreeBSD
Current assessment:
- Phase 5.2 is now satisfied on the current FreeBSD prototype track
- the next step is no longer “can we emit a derivation at all?” but “can the same daemon/store path accept and execute a derivation-backed build request successfully?”
