I3015 — serve and mcp discover the repository once, through the shared model

✕BLOCKED wave 1 · p0 · implementation profile · parallel safe

Part of two-folder-integration — A repository that adopts Majordomus gains two directories and two lines, and can give them back.

Objective

majordomus serve and majordomus mcp take the repository App::load discovered instead of discovering it again (commands/serve.rs and commands/mcp.rs today discover beside App::load), and env, web and guard read the same cell, so every entry point of the executable pays one discovery.

Why

The second slice of I1105. The 2026-10-20 survey counted two discoveries at the startup of serve, serve status and mcp, and only App::load's discovery is timed, so the others are never measured.

Current state

serve.rs and mcp.rs call Repository::discover and then App::load, which discovers again.

Desired state

One discovery at each entry point, measured where it happens.

Scope

• apps/majordomus-cli/src/commands/serve.rs
• apps/majordomus-cli/src/commands/mcp.rs
• apps/majordomus-cli/src/commands/env.rs
• apps/majordomus-cli/src/commands/web.rs
• apps/majordomus-cli/src/commands/guard.rs
• apps/majordomus-cli/src/app.rs
• apps/majordomus-cli/tests/hot_path.rs

Out of scope

• The capabilities' Repository::open calls (I3016)

Dependencies

• I3014○READY The repository is found once per process, and a counter proves it

What waits on this

• I1105✕BLOCKED The repository is discovered once, into one model
• I3017✕BLOCKED Discovering the repository outside the model is refused

Acceptance criteria

• After serve's startup and after an MCP initialize, repository_discoveries is 1, asserted in tests/hot_path.rs
• The discovery phase is timed at every entry point that discovers

Validation

• cargo test --workspace --all-features

Evidence required

• one_discovery_at_every_entry

Evidence

None recorded. Every token above needs a command or an artifact behind it before this issue can be completed; narrative is refused.

Those three fields, the evidence above and the state of the dependencies are all the status is made of. There is no status field to disagree with them.
