+## P36 build outcomes (2026-08-13)
+
+Issues #588–#597, milestone P36 (17 commits, 4a9be6f..a444d75, branch
+`p36-cy2026-rule`). Deviations and measurements vs the design:
+
+- **Comment farm was already complete** — the design's "only ~2,905 of
+  14,092 extracted" understated prior work: all 2,905 attachment-bearing
+  comments had extractions; the remaining ~11.2k are body-only (abstract
+  fallback covers them), and the whole corpus (164k comments, 726,620
+  chunks incl. 62,486 for CMS-2025-0304) was already embedded post-P33.
+  #596 reduced to rule-text indexing.
+- **Rules collection**: 5,769 chunks (2,254→2,208 NPRM CMS-1832-P,
+  3,611→3,561 final CMS-1832-F) after an inline-HTML-strip fix round and
+  force reindex; final-rule bib item gained `cms-rule:CMS-1832-F`.
+- **pfs.rvu_proposed**: 14,169 rows (NPRM Addendum B), in aco.duckdb +
+  replica + DuckLake; `cms.ingest_log` provenance (18 rows/2 runs) with
+  sha256, FR citation, pincite. Column names deviate from `pfs.rvu`
+  (`modifier`/`mod`, `nonfac_pe_rvu`/`non_fac_pe_rvu`) — follow-up #607.
+- **CY2026 NPRM parameters** (all source-verified at 90 FR 32352 et seq.):
+  proposed CF 33.4209 non-QP / 33.5875 QP, anesthesia 20.5728/20.6754,
+  BN adjustor 1.0055, telehealth originating-site fee $31.85, comment
+  close 2025-09-12.
+- **qpp module**: QP thresholds 75%/50% (partial 50%/35% — patient-count
+  value is a disclosed inference), revenue nominal-risk standard 8%
+  (414.1415(c)(3)(i)(A), established 83 FR / 2018-24170); the
+  benchmark-based standard (c)(3)(i)(B) is stated nowhere in the corpus
+  as a bare percentage → `None` with notes. APM incentive sunset and the
+  first-year QP/non-QP CF split (payment year 2026) encoded with
+  citations at 90 FR 49928/49979–49980.
+- **Citation correction found by final review**: `RULES[2026]`'s
+  final-rule citation had been "90 FR 101174" — that is the *OPPS* final
+  rule's citation; the PFS final rule is **90 FR 49266–50481** (CFs at
+  49961). Corrected in registry + notebook (a444d75). Design note: the
+  spec itself restated the wrong citation as current state; future rule
+  cycles should re-verify pre-existing registry citations against newly
+  captured text.
+- **Interstitials landed on the branch**: #598 (test poisoned global
+  polars.DataFrame → duckdb replacement-scan cache corruption; full
+  suite 14,023 green post-fix), #599 (stale .git/hooks copies removed),
+  CVE bumps aiohttp 3.14.3 / pyasn1 0.6.4 / cryptography 50.0.0
+  (#581–#587 closed with per-CVE exploitability rationale).
+- **Notebook**: `notebooks/cy2026_pfs_proposed_rule.py`, 5 sections, all
+  values registry/lake-sourced (thresholds interpolated after review
+  fix), 18/18 headless integration green. CMS Table 92 (specialty
+  impact) is a scanned graphic → clearly-labeled CPT-range proxy.
