A single-agent code review of this branch's diff (builder/pipeline/
publisher/sanity/hash + main/config/fetcher/state/verifier changes)
found six real issues, all fixed here:
- builder.rs: validate_shell_safe only rejected a literal single quote
and newline, written for the single-quoted PKGBUILD fields. But
asset_name (via install_source) and binary_name land in the install()
line, which is necessarily double-quoted so ${srcdir}/${pkgdir} can
expand — where $, backtick, and backslash are still live. Not
currently exploitable (the one variable component, version, is already
independently constrained by validate_pkgver's strict charset), but a
latent gap relying on that coincidence rather than the validator
actually covering its real use context. Widened the reject-list to
cover both quoting styles, added regression tests including one at the
generate_pkgbuild level. Corrected SPEC.md's "single-quoted" claim to
match.
- pipeline.rs: a verification failure returned Ok(()) from
process_package, so run_check never counted it as a failure and the
process exited 0 even on a failed cryptographic/attestation check —
exactly the event a monitoring setup (systemd OnFailure=, cron
mail-on-error) most needs a non-zero exit to catch. Now bails, which
run_check already treats as a package failure. Added an integration
test against a mocked GitHub server exercising this exact path.
- builder.rs: find_built_package hardcoded the .pkg.tar.zst suffix, so a
box with a different PKGEXT in makepkg.conf would report a false
"makepkg failed" for a build that actually succeeded. Widened to match
any .pkg.tar.* compression. Added direct unit tests (it had none).
- pipeline.rs: a newer tier 4-6 version silently overwrote a still-
unreviewed older pending version with no indication anything was
superseded. Now says so explicitly.
- hash.rs: builder/verifier each read a whole downloaded artifact into
memory via std::fs::read just to hash it, doubling peak memory for no
reason since the file's already on disk. Added sha256_hex_file,
streamed in fixed-size chunks; both callers switched to it.
- Deduplicated two near-identical test-only "write an executable shell
script" helpers (publisher.rs, sanity.rs) into a shared
src/test_support.rs.
75 tests (was 63), cargo make ci clean. Re-verified end to end against
the real astral-sh/uv release after all six fixes — build, sanity check,
and publish into a scratch repo all still succeed.

Researched current industry practice on code organization/maintainability
(Ousterhout's deep modules and information hiding, package-by-feature vs.
package-by-layer, functional-core/imperative-shell testability, tech-debt
prevention via ADR-equivalent inline rationale) and wrote it into
ARCHITECTURE.md as a set of concrete, project-specific rules rather than
a generic essay — each principle cites a real example already in this
codebase or fixed by this commit. Cross-linked from SPEC.md, which stays
about product design, not code organization.
Applied it to this PR's own code:
- Pulled process_package/fetch_and_verify/build_and_publish/run_review/
approve out of main.rs into a new pipeline.rs. main.rs's own main() had
grown to 278 lines and zero tests by treating "it's just the entry
point" as an excuse to skip separating logic from wiring; now main.rs
is argv dispatch only.
- Extracted decide_tier_action as a pure function (verification outcome +
pending-state -> what to do), replacing dispatch logic that was
previously inlined into a function that also made the real network/
build calls. Four unit tests, no I/O, covering all four outcomes.
- Added a `//!` module doc comment to every file touched in this branch,
each stating that module's one job in a sentence, per the "deep
modules" principle the spec argues for.
Coverage's reported total drops (94% -> 78%) because pipeline.rs is
deliberately NOT excluded from it the way main.rs is, even though it's
mostly the same kind of untestable I/O orchestration — excluding it would
hide decide_tier_action's real unit-test coverage along with the untested
parts. Noted inline in Makefile.toml/ci.yml so the number doesn't look
like a quality regression at a glance.
Also added a project reference memory pointing at ARCHITECTURE.md rather
than duplicating its content there, per this session's own memory-hygiene
rules (architecture/conventions are derivable from the repo and shouldn't
be duplicated somewhere that can go stale).
