"""Integration tests for  (REMEDIATE): tree → write_emit_ctx → emit_result.

The defect: parse_wave.py writes `_partial_reason` and `_pending_fetches`
into the tree on disk. emit_result.py reads `ctx["partial_reason"]` and
`ctx["pending_fetches_count"]` from the emit ctx. But write_emit_ctx.py
NEVER populated those ctx keys from the tree — they silently defaulted to
empty / 0 on every run. Depth-cap truncation was invisible downstream.

These tests exercise both halves of the wiring:

    test_write_emit_ctx_reads_tree_partial_signals
        fake tree JSON → write_emit_ctx → assert ctx keys populated.

    test_end_to_end_tree_surfaces_partial_reason_in_result_block
        tree → write_emit_ctx → emit_result → assert RESULT block carries
        PARTIAL_REASON + PENDING_FETCHES_COUNT. End-to-end — this is the
        test both reviewers called for.

Missing-tree behavior is also covered so early-abort paths still work.
