Cx Dev Log — 2026-07-26

#cx #programming

No commits landed today. The test matrix sits at 380 pass, 0 fail on main, same as yesterday. v0.3.2 is stable and nothing moved. This is a status-check log rather than a progress report.

Where things stand

The 0.3.2 release shipped with gene/phen support and has been clean since it landed. The seven documentation site commits from July 24 are still branch-local on site, unmerged. The eight example file rewrites (hello.cx, fibonacci.cx, fizzbuzz.cx, arrays_and_loops.cx, error_handling.cx, generics.cx, structs_and_methods.cx, tbool_uncertainty.cx) have been parked on the daily-log-2026-07-04 branch since late June. Those are tutorial-style expansions: block comments explaining language features, reorganized code for better demonstration, more diverse examples. About 280 insertions and 78 deletions across the eight files.

Neither of these queued items moved today.

0.3.3 scope

The next milestone is scoped but not started. Three items define it:

Array-return lowering. Same ABI-shape work pattern as the struct-return fix from 0.3.2. The approach is established; this extends it to array types.
Generic-function lowering. Bringing T: GeneName bounded generics into the Cranelift JIT path. This is the piece that turns generics from a type-system feature into something that actually compiles and runs.
Expression receivers. Unlocking chained method-style calls and operator expressions on user types beyond the current single-expression restriction.

None of these have started. They carry forward as the primary engineering targets once active development resumes.

Pending cleanup

Two items that could land independently of 0.3.3:

The site branch has seven verified commits from a documentation sprint on July 24. Whether these merge to main or deploy independently is still undecided, but the content is ready.

The example file rewrites have been sitting for roughly a month. They are a self-contained set of changes and could ship as a small cleanup PR without blocking or depending on anything else.

The roadmap's "Last updated" date was corrected from 2026-07-04 to 2026-07-26 today. The content itself had already been reconciled by the 0.3.2 merge (PR #352), but the date line had not been bumped. No substantive roadmap changes.

What's next

The same three predictions from yesterday carry forward unchanged: 0.3.3 implementation work, site branch merge or deployment, and a README feature audit to update sections that still describe pre-gene/phen capabilities. None were addressed today.

When work resumes, array-return lowering is probably the lowest-friction starting point since the struct-return pattern from 0.3.2 provides a direct template.
