# Role pipeline: analyst → architect → brief_echo → planner → implementer ⇄ reviewer
#
# Each stage produces a typed artifact that the next stage `needs`, so work flows forward
# without a human relaying notes. The decision journal (pinned into every stage's context)
# carries steering/approvals/verdicts across the whole run, so the reviewer sees the same
# ground truth as the planner.
#
# The implementer⇄reviewer loop is gated by review_report.verdict:
#   approved          → done
#   changes_requested → back to implementer (capped by implementer.max_retries, then escalates)
#

#     The brief_echo gate diffs the restatement against the original analysis;

# 4. Implement the plan. Writes files (jailed to the workspace). The loop target —
#    max_retries here caps how many review→implement refinement rounds are allowed.
#    Optional: a `writes` manifest (workspace-relative globs) hard-bounds where this
#    stage may write — a FILE_WRITE outside it is blocked as scope creep. Left open
#    here because the targets are task-specific; a task-scoped workflow would set e.g.
#      writes = ["core/sessions/**", "testing/sessions/**"]
#    Optional: `static_analysis` runs deterministic tools (compiler/detekt/formatters)
#    against the patch BEFORE the reviewer (role-reliability §5). A non-clean command
#    fails this stage retryably with its output fed back verbatim, so only static-clean
#    code reaches the reviewer — the reviewer never spends inference on what tools catch
#    for free. Commands are workspace-specific, so left commented; a Kotlin/Gradle repo
#    would set e.g.
#      static_analysis = ["./gradlew compileKotlin -q", "./gradlew detekt -q"]
