ai-sdlc

Shared foundation for the sdlc-* skill library: the engineering standard every session must meet, and the .ai-sdlc/state.md / journal.md file spec for cross-session handoff. Load when any sdlc-* skill references it or when reading/writing those files.

End-of-work discipline for project repos: hostile validation of the diff before declaring work done, and handoff (settle the tree, update state.md, append the journal) before ending a session with changes. Triggered by the claim, not the diff — use before any done/ship verdict, even for small edits.

Start-of-work discipline for project repos: orientation before the first substantive task of a session, and planning whenever a task is multi-step, risky, ambiguous, or touches config that propagates beyond this machine. Execution is governed by sdlc-core.
