Remediates reviewer findings F1, F2, and F3 from review 483 on PR #770.
F1 (blocking): _current_runtime_mode_report derived the runtime-gate alignment
input as realpath(workspace_root) == process_project_root, redefining
workspace_roots_aligned. Its established meaning is ctx["roots_aligned"]
(canonical_repo_root == process_project_root) — a repository-level question.
Because the global worktree rule requires all task work to live in a branches/
worktree, the old derivation reported aligned False for exactly the sessions
that are configured correctly, raising unsafe_process_root_workspace_alignment
and refusing every non-read operation once an author, reviewer, or merger
namespace held a worktree binding. The gate is now fed ctx["roots_aligned"].
F2 (blocking): _current_runtime_mode_report cached its first result into
_STARTUP_RUNTIME_MODE, which was initialised to None rather than captured at
import, and the read-only refresh=True path seeded it too. Session-scoped
fields (active_task_workspace and its derived alignment) and mutable fields
(dirty_files) were frozen for the process lifetime, so the acceptance
criterion 7 dirty-runtime blocker stopped applying after the snapshot and one
session's binding decided alignment for every later session.
Immutable process facts (process root, branch, head, checkout-ness) are now
captured at import as _STARTUP_RUNTIME_FACTS, matching the #420 parity
baseline. Dirty state, workspace binding, and alignment are recomputed on every
call. A new stable_control_runtime.observe_dirty_files() splits out the one
runtime fact that legitimately changes during a process lifetime;
observe_runtime() delegates to it so the parsing lives in one place. refresh is
retained for the read-only reporting path but no longer selects a cache, so a
read-only call can neither seed nor weaken a later mutation decision.
F3 (major): no test exercised the real derivation — every server-wiring test
asserting a healthy runtime permits mutations patched
_current_runtime_mode_report with a fixture whose workspace_roots_aligned was
True. New TestServerWiringRealDerivation patches only the derivation's inputs
and lets the real function build the report:
- a clean stable control checkout plus a correctly bound branches/ worktree
permits an otherwise authorized mutation;
- misaligned process/canonical roots fail closed;
- newly dirty task state is detected after an earlier clean read;
- a read-only refresh cannot freeze a permissive mutation result;
- an unresolvable binding reports unknown alignment, never alignment proof.
Acceptance criteria 6, 8, 10, and 11 are unchanged and untouched.
