conductor eb3a2c681c fix(scaffolding): T22 — connect the MiMo edge and apply the meaning gate on the native path
Reality-wins audit of the accepted Scaffolding V1 system against the live
repo/runtime found three genuine wiring defects (no architecture invented):

1. The MiMo edge was DEAD. `~/.mimocode/hooks/builder-bridge.ts` hardcoded
   the ephemeral interpreter `/tmp/ci-venv/bin/python`, which no longer
   exists, so every bridge call failed and the hook silently degraded —
   MiMo received NO Rune Core preflight at all (zero fire-log lines). The
   hook was also UNVERSIONED (no canonical copy), which is how it rotted.
   Repair: canonical source `config/mimo-hooks/builder-bridge.ts` with
   durable interpreter resolution (env override > repo venv > user venv >
   /usr/bin/python3), installed + hash-verified + drift-checked by
   `install_mimo_hook.py`, which now manages a hook SET rather than one file.

2. The native path skipped the canonical meaning layer. `construction_intent`
   (the §17J/§17L/§17M intent resolver: interrogative structure, negation,
   request modals, referent/proposal resolution) existed but was imported
   ONLY by tests. `rune_operator._construction_activation` went straight to
   `classify_mode`, so a pure question carrying a target reference
   ("explain how this module works") classified EXISTING_PROJECT_CHANGE and
   recorded a construction activation for a discussion turn. Repair: the
   intent layer now resolves MEANING before the ONE classifier decides mode
   (the boundary the intent module documents). DISCUSSION maps to
   NOT_CONSTRUCTION — the canonical vocabulary is unchanged, an explicit
   user override (/scaffold-mode) outranks the gate, and an unavailable
   intent layer preserves the previous behaviour exactly rather than
   silently changing governance.

3. The shared Construction Context reported a TERMINAL contract as active.
   `construction_context()` selected on `status == "open"` alone, so 8
   contracts with phase `abandoned` (terminal) were reported as the active
   construction. Repair: terminal phases are now DERIVED once from the
   canonical transition table (`scaffold.TERMINAL_PHASES`), and a contract
   is active only when its phase is non-terminal.

Also: the bridge capsule now surfaces the active Scaffolding construction
(contract/phase/scope/obligations/next-action) to the builder as a
read-only projection of the shared Construction Context — the MiMo edge of
state Scaffolding already owns. Inject-nothing is preserved when no
contract is active; the projection never mutates and degrades to [].

Spine projection refreshed (import graph legitimately gained importers).

Honest boundary: no byte-level enforcement point exists. `tool_executor.py`
never consults construction state, so the 19A invariant gates only the
/build-start route. Establishing MiMo-surface enforcement is NEW
architecture (a tool.execute.before governance hook) and was NOT built
here — it is recorded as the exact remaining blocker.

Verification: 511 passed across the construction/operator/bridge/hook/
structural/parity suites; native-default matrix 12/12; real operator-path
proof with fresh-process readback (EXISTING_PROJECT_CHANGE activated,
question -> NOT_CONSTRUCTION, PROJECT_BUILD bootstraps scaffold + registry);
installed hook invoked directly -> capsule injected + fire log written.
LOCAL_MODEL_COMPUTE_EXECUTED = NO.

- 21.2B: resolve_cwd returns repo_identity (git:<path> stripped) not
  scaffold_location; worktree override; unknown project raises; no
  repo → refuse; 8 held-outs incl. old-bug reproduction.
- 21.2C: wait_guard covers time.sleep(N) (inline + heredoc), polling
  loops (while/until + status on full command), repeated delay+status;
  7 new held-outs; legitimate cases still pass.
- 21.2D: canonical hook source at config/mimo-hooks/event-wait-guard.ts;
  scripts/install_mimo_hook.py verifies hash; drift test detects
  canonical↔installed divergence.
- 21.2G: programme_gates.py — mandatory gates end in PASS/BLOCKED/
  WAIVED_BY_USER only; GateDemotionError prevents mandatory→optional
  demotion; 6 held-outs.
