Devlog: February 27, 2026

A sprawling day. Klar dominated the commit log with a full milestone sweep of the Meta Layer. Changesmith shipped a significant feature alongside a version bump and dependency cleanup. Lodex made a major architectural pivot. TimeTower and AirTower both wrapped up implementations. ClaudeCodeSettings and Marketing got quiet but meaningful attention too.

Klar

Thirteen commits. The Meta Layer is now complete.

Milestones M.1 through M.8 were all checked off and documented in PLAN.md — that's the full Meta Layer arc, shipped in one push. The work covered the klar meta CLI command (M.8), custom annotation definitions and validation (M.7), pure function verification in the type checker (M.6), and path separator unification to :: with a path param type. New builtins landed too: env_get, env_set, fs_stat, timestamp_now, and process_run — the kind of stdlib primitives that make a language actually usable for real scripts.

Three rounds of PR review feedback were addressed before the merge, which is a sign the Meta Layer is doing something non-trivial and worth getting right. A stdlib plan for Lodex infrastructure needs was also documented — a signal that Klar and Lodex are now deeply coupled in the roadmap. The .meta-test-results.json file got a gitignore entry to keep the working directory clean.

This is one of the most productive single-day pushes Klar has seen. The Meta Layer gives the language a first-class way to annotate and query code — that's infrastructure with long legs.

Changesmith

Five commits, a version bump to 1.9.0.

The headliner: security signal detection, audience inference, and prompt improvements in core. That's a meaningful feature — Changesmith can now detect security-relevant changes and tailor its output to different audiences. Combined with the new /hub resource center and a refreshed /docs with MDX, this is a real release, not just a patch.

Under the hood: the checkly dependency was upgraded to 7.3.0 and a minimatch audit override was fixed. Prettier formatting was applied to the commit-parser. The version bump to 1.9.0 makes it official. Clean branch, proper merge — CI is in good shape.

Lodex

Two commits. Big pivot.

Lodex is switching from Rust to Klar, replacing native SDKs with a CLI + HTTP API approach. That's an architectural decision with real implications — it means Lodex will run on top of the Klar runtime rather than compiled Rust. Given that Klar just completed its Meta Layer and stdlib foundation, the timing makes sense. A PHILOSOPHY.md was added alongside a rename from "collection" to "exploration tree/trail" terminology, which suggests the project's conceptual model is solidifying around a specific metaphor.

TimeTower

One commit: PLAN.md removed after completing implementation phases 1–9.

When the plan file goes away, it means the plan is done. Nine phases — from initial structure through auth and persistence — are complete. TimeTower appears to be feature-complete for its first milestone. Quiet commit, loud signal.

AirTower

A PR merged: Claude Code ecstatic-kirch branch. Without visibility into the PR contents, the branch name suggests an AI-assisted worktree session. AirTower continues to iterate on its developer tooling surface.

ClaudeCodeSettings

Three commits to the global Claude Code configuration.

PLAN.md format conventions were added as a global rule, git worktree awareness was added to the status line, and the project layout was updated with a Klar path fix and agent teams additions. These are infrastructure-level changes that affect every project — a meta-investment that pays dividends across the whole dev environment.

Marketing

One commit: a nano-banana image generation skill was added alongside a gitignore update. Nano-banana is Athena's image generation capability via Gemini. Getting it into the Marketing repo suggests some creative or visual work is on the horizon.
