From 576810d928c4be3164dc9bda5bbad6eefee3c11e Mon Sep 17 00:00:00 2001 From: SaschaBa <18143567+SaschaOnTour@users.noreply.github.com> Date: Wed, 22 Apr 2026 00:15:52 +0200 Subject: [PATCH 01/15] refactor: introduce RlmSession, dissolve operations/, enforce adapter thinness MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CLI and MCP handlers now route every tool call through a single `application::session::RlmSession` that owns the `Database` handle and `Config`. Adapters do nothing but parse arguments, call one session method, and emit the result through their formatter. Key changes: - New `application::session::RlmSession`: one method per tool (search, read_symbol, read_section, overview, refs, context, deps, scope, partition, summarize, diff, files, verify, supported, stats, quality, replace_preview/apply, delete, insert, extract). Static methods for `index_project` and `supported`. - New `application::edit::write_dispatch`: shared orchestration (op → reindex → splice → record savings) for replace / delete / insert / extract. Adapters build an input struct and call. - New `application::query::read`: symbol + section logic lifted out of both adapters. MCP no longer imports `domain::chunk::Chunk`. - New `application::middleware` (moved from `interface::shared`): `record_operation` / `record_file_query` / `record_symbol_query`. - Stats/savings/quality consolidated: MCP `stats(savings?, since?)` replaces the standalone `savings` tool; new MCP `quality` tool mirrors `rlm quality`. - `application::savings` and `application::index::output` are now the physical homes for what used to live under `operations/`. - `src/operations/` deleted in full. `operations::refs::get_refs` was dead code (only called by its own tests); removed. Rustqual enforcement: - New `[[architecture.pattern]] adapters_no_direct_infrastructure` forbids `crate::db::`, `crate::ingest::`, `crate::application::index::`, `crate::domain::{chunk,file,reference}::`, and `crate::application::savings::` inside every CLI/MCP handler file. Test-only helpers are exempt. - `[architecture.layers.application]` no longer lists `src/operations/**`; the transitional layer is gone. Quality gates: - cargo build: clean - cargo clippy --all-targets -- -D warnings: clean - cargo nextest run: 825 passed, 6 skipped, 0 failed (2 tests removed with the dead `operations::refs::get_refs`) -

Rework cycles avoided + +A grep-based workflow over-matches (string hits that aren't semantic +refs) and under-matches (trait dispatch, re-exports, macro-generated +methods).

This isn't just a time savings — an agent +working from a noise-contaminated grep list will undercount and +overcount simultaneously, producing edits that miss some real call +sites and break unrelated code. + +### 3.
