From 3355daff4b63ce6d1be72b5f487c520d05c37ac5 Mon Sep 17 00:00:00 2001 From: Leynos Date: Fri, 10 Apr 2026 23:48:22 +0000 Subject: [PATCH 01/30] docs(execplans): add ExecPlan for converting root manifest to hybrid workspace This new ExecPlan outlines the staged approach to convert the root Cargo.toml into a hybrid workspace manifest as part of roadmap item 10.1.1. It details the constraints, risks, tolerances, progress checkpoints, and testing strategy for preserving the root package as the default workspace member while enabling formal verification infrastructure in subsequent steps. The document also specifies documentation updates and behavioral regression coverage needed to support this workspace transition without disrupting existing workflows.

Date/Author: 2026-04-10 / Codex. + +## Outcomes & Retrospective + +(To be completed when implementation lands.) + +## Context and orientation + +Relevant repository areas: + +- `Cargo.toml` currently defines only the root `wireframe` package. +- `wireframe_testing/Cargo.toml` depends on the root crate by path but is not a + workspace member today. +- `docs/roadmap.md` owns the 10.1.1 acceptance criteria. +- `docs/formal-verification-methods-in-wireframe.md` is the relevant design + document and already defines the eventual hybrid-workspace end state. +- `docs/developers-guide.md` is the correct place for contributor-facing Cargo + workflow guidance. +- `docs/users-guide.md` must be inspected for any consumer-facing fallout, + although none is expected. +- `tests/` already contains both `rstest` integration tests and the + `rstest-bdd` structure under `tests/features/`, `tests/fixtures/`, + `tests/steps/`, and `tests/scenarios/`. + +The most important design nuance for this item is the distinction between the +**stage-1 workspace shape** and the **final formal-verification end state**. +Item 10.1.1 should only make the root manifest workspace-aware and keep the +root package as the default member. Item 10.1.2 should then add the dedicated +verification crate and extend the member list. + +## Plan of work + +### Stage A: confirm the staged workspace contract + +Resolve the staging question before editing files: + +1. Verify that the root manifest can become a hybrid workspace without adding a + placeholder verification crate. +2. Lock the 10.1.1 contract to "hybrid workspace now, verification member in + 10.1.2" unless Cargo proves otherwise. +3. Identify the minimal file set for this item: + `Cargo.toml`, design docs, developer docs, optional user docs, roadmap, and + new regression-test files. + +Go/no-go: proceed only once the staged contract is written into this ExecPlan +and ready to be mirrored into the formal-verification design doc. + +### Stage B: convert the root manifest + +Edit the root manifest to add the workspace section while preserving the root +package. + +Planned manifest changes: + +- add `[workspace]`, +- set `members = ["."]` for 10.1.1, +- set `default-members = ["."]`, +- set `resolver = "3"`. + +Then validate the raw Cargo behaviour immediately: + +- `cargo metadata --no-deps --format-version 1` +- `cargo build` +- `cargo test --workspace` + +If the hybrid layout changes package resolution, path dependency behaviour, or +test target discovery, fix those regressions before moving on to test or docs +work. + +Go/no-go: continue only when the repository builds and the workspace metadata +matches the staged 10.1.1 contract. + +### Stage C: add `rstest` regression coverage + +Add a focused integration test, likely `tests/workspace_manifest.rs`, that uses +`#[rstest]` fixtures to gather and reuse repository metadata. + +The test should validate stable invariants only: + +- the repository now exposes a workspace, +- the root package is a workspace member, +- the root package is the default member, +- 10.1.1 does not unexpectedly widen default-member coverage. + +Prefer a small local metadata helper in `tests/common/` if more than one test +needs to inspect the `cargo metadata` output. Do not invoke nested +`cargo build` or `cargo test` from these tests. + +Go/no-go: continue only when the new `rstest` coverage passes reliably in +isolation. + +### Stage D: add `rstest-bdd` behavioural coverage + +Add a small BDD slice that expresses the contributor-facing behaviour of the +new layout, for example: + +- feature file under `tests/features/workspace_manifest.feature`, +- fixture world under `tests/fixtures/workspace_manifest.rs`, +- step definitions under `tests/steps/workspace_manifest_steps.rs`, +- scenario bindings under `tests/scenarios/workspace_manifest_scenarios.rs`, +- module wiring in `tests/fixtures/mod.rs`, `tests/steps/mod.rs`, and + `tests/scenarios/mod.rs`. + +The scenario should describe the observable contract in plain language: the +repository acts as a hybrid workspace, while the root package remains the +default target for ordinary root-level cargo commands. The implementation +should inspect metadata or other stable manifest observations, not recursively +re-run the full build. + +Go/no-go: continue only when the new BDD coverage compiles and passes alongside +the existing feature suite. + +### Stage E: documentation and roadmap updates + +Update the design and contributor documentation once the manifest and tests are +stable. + +Required documentation work: + +- update `docs/formal-verification-methods-in-wireframe.md` so the + "Root `Cargo.toml` changes" section explains the staged rollout: + `members = ["."]` in 10.1.1, then `[".", "crates/wireframe-verification"]` in + 10.1.2; +- update `docs/developers-guide.md` with hybrid-workspace semantics and clear + guidance on when to use plain cargo commands versus `--workspace`; +- inspect `docs/users-guide.md` and update it only if the workspace change + alters anything a library consumer needs to know; +- mark 10.1.1 done in `docs/roadmap.md` after all gates pass. + +Go/no-go: proceed to final validation only when the docs reflect the actual +implemented contract. + +### Stage F: validation and quality gates + +Run targeted checks first, then the full repository gates.

It improves error handling by returning io::Error when the prefix length is invalid rather than panicking or assuming correctness. Additional changes include: - Updating callers to handle the Result return value. - Adding comprehensive tests using rstest to verify correct buffer placement for all supported prefix sizes and endianness. - Enhancing documentation in docs/developers-guide.md for fill_buf_with_prefix and ServerShutdownHandle. - Various minor fixes and improvements in message_assembler series tests and workspace manifest test fixture. This refactor improves robustness and correctness in frame conversion logic.
