v0.7.8

Added

• agent-compass evidence builds the artifact a completion claim owes. It
  collects every JUnit report and screenshot into a self-contained bundle at
  .agent/evidence/ — index.html for a human, summary.md for the pull
  request — and the status is binary: complete only when nothing failed and the
  promised screenshots exist. Configure it with the evidence key of
  agent-compass.commands.json. Without that key it discovers the files and
  says so in the report, because a discovered count is a weaker claim than a
  declared one.
• A before/after report for a spec'd change. evidence --change <slug> --phase start records the proof and a SHA-256 snapshot of the workspace;
  --phase finish re-runs, diffs the snapshot, lists the changed and tested
  files, reads the acceptance criteria out of the spec, and renders the before
  and after screenshots side by side under .agent/changes/<slug>/. It is a
  gate: it exits non-zero unless the after-proof is complete and something
  actually changed, so a green suite over an empty diff cannot pass.
• docs/guidelines/definition-of-done.md. The formalism behind the
  Completion Gate: the AUTO / PR / REVIEW / N/A proof types, the rule
  that no level compensates another, the blocking conditions, the actions an
  agent may never take against a test, and an exception procedure that needs an
  owner and a deadline and then expires.
• docs/guidelines/accessibility.md, the first accessibility rules in the
  compass, plus the keyboard-path-before-done instinct. An automated audit
  reads the rendered tree; it cannot tell you that Tab skips your new button.
• specs/change-spec-template.md, whose ## Acceptance criteria and
  ## Expected proof scenarios headings are read literally by the change
  report, and the evidence-outlives-the-claim instinct.

Changed

• docs/guidelines/testing-tdd.md gained the proof half of testing: a fixed
  screen-profile matrix, the difference between regenerable execution evidence
  and committed visual baselines that only a human may update, the evidence
  commands, and the forbidden anti-patterns.

Fixed

• code-intel status reports an indexed repository as indexed. The project
  listing is read for a root path under five key names, and
  codebase-memory-mcp 0.10.5 returns the one that was missing, root_path.
  Every status read therefore ended on "this repository indexed: no", whatever
  the graph held. doctor never read that field and was correct throughout.
