 ### Fixed
 
+- 999 now accepts SNIP 3+ findings with `E` instead of rejecting every ERROR. HIPAA acknowledgement selection follows the implementation version and enabled agreement expectation; outbound HIPAA ST carries its implementation identifier.
+- Qualified HL/NM1 anchors distinguish healthcare hierarchy levels; repeated loop names under different parents retain separate occurrences. Situational rules inherit direct ancestor segments without borrowing values from sibling occurrences.
+- Review/Result records expose identifiers only. A marked RC.5 PHI logging bridge prevents core upsert query diagnostics from copying claim/member values into logs.
+
 - Inbound apply no longer fails with a null-pointer error on a target table that has no associations (flat tables such as the 214 status sample).

+## HIPAA and PHI
+
+Original **QQQ baseline guides** cover 837P (005010X222A1), 837I (005010X223A2),
+835 (005010X221A1), 270/271 (005010X279A1), 276/277 (005010X212), 834 (005010X220A1)
+and 999 (005010X231A1). These are in-house structure and usage baselines, not licensed TR3s.
+No TR3 text or full licensed code lists ship. Hosts may import their licensed guides.
+
+SNIP 1–2 covers envelopes and the active guide. SNIP 3 uses exact decimals for claim charges,
+claim/line CAS adjustments and payments less signed PLB adjustments (zero tolerance). SNIP 4
+rules run per loop occurrence, including dependent patients, claim/line dates, diagnoses,
+subscriber demographics and benefits-or-rejection responses. SNIP 3+ findings produce `E` and
+an exception; SNIP 1–2 errors produce `R`. HIPAA replies use 999 when acknowledgement is enabled.
+SNIP 5 includes ICD-10 diagnosis shape, NPI Luhn with the 80840 prefix, and US ZIP shape.
+`ExternalCodeSetProvider.isValid(codeSet, code, asOf)` supplies licensed membership checks for
+EXTERNAL code lists; without it, only formats are checked. The System widget reports that state.
+
+Healthcare agreement documents default to PHI and SNIP 4. Clinical keys go only to
+`edi_transaction.phiBusinessKey`; validation excerpts, acknowledgements, events, exceptions,
+alerts and process summaries contain no submitted clinical values. Healthcare sample maps and
+host tables live **only in test sources/resources** and use seeded synthetic patients and claims.
+Their NPI `1234567893` is a checksum test fixture, not an asserted provider identity.
+
+**The host must encrypt the database at rest and should install qbit-secured-data.** Payloads
+are always AES-GCM encrypted; PHI columns rely on host database encryption. RC.5's
+`EdiClassifications` stand-in marks PHI/PII/CONFIDENTIAL and denies PHI AI exposure, but does not
+mask values. Without secured-data policies, a user with table access can read PHI columns.
+The home explicitly reports this limitation. Use record-level audits on host PHI target tables
+until core classified-value audit protection is available.
+
+RC.5 also logs query criteria verbatim. The marked `PhiLogScope` bridge suppresses synchronous
+logger diagnostics during PHI mapping/application and preview; ordinary value-free EDI events
+remain persisted. It changes no logger levels and does not suppress other threads. Replace both
+bridges with core secured-data support at 4.1.0-RC.6. Map samples use record-level audits to avoid
+copying expected-result PHI into audit details. Host code outside these scopes must protect its
+own logging, audits and asynchronous work.
+
+Download Raw Document uses a session-bound process grant, rechecks `edi.raw.download` and record
+read/partner access at download time, streams decrypted bytes without local files, and records
+`RAW_DOWNLOADED` with the user and row references, never content. Download filenames are generic.
+
+`PhiCanaryTest` scans every five-character marker window through gateway/HTTPS intake, forced
+SNIP 2/3/4 errors, mapping/apply, 999, replay/resend, Review/Result, alerts, DEBUG logs, all EDI
+query exports and all home/child widgets. FULL exports exempt only PHI-classified columns;
+RC.5 HIDDEN field-lock exports have no exemptions. MASKED tiers and the optional Quick Search
+qbit require the newer secured-data integration and are not claimed by these RC.5 tests.

+## Phase e implementation notes (2026-10-14)
+
+- Core RC.5 logs full query criteria, including PHI upsert keys. `PhiLogScope` is a scoped,
+  marked bridge to suppress synchronous diagnostic logging during PHI map/apply and previews;
+  it leaves unrelated threads and persisted value-free events intact. Remove with the core
+  classification/logging bridge at RC.6. Map samples use record-level audits on RC.5 because their
+  expected-result column can contain PHI. Host asynchronous code, target audits and queries outside
+  these boundaries still need host secured-data protection. Raw downloads use RC.5's existing
+  session-bound storage grant and an `edi_event` audit rather than a not-yet-available access log.
+- Situational rules bind to their occurrence and inherit only direct ancestor segments, so a
+  sibling line's service date cannot satisfy another line. Fixed loop-head qualifiers distinguish
+  HL/NM1 roles; the same 2300/2400 names can occur under subscriber and patient parents.
+- The 271 baseline requires benefits or an AAA rejection for a traced response; it does not
+  perform cross-document 270/271 correlation. Provider differences that cannot be inferred from
+  the submitted document belong in a companion guide or host rule; no rendering provider is
+  invented from an absent identifier.
+- Healthcare maps and sample target tables are test-only, per the phase-e scope. The 837 sample
+  map is a single-claim example with service-line associations; the validator supports multiple
+  claims and checks each independently. The 835 and 834 samples map multiple claim/member
+  associations. These are baseline examples, not a complete licensed TR3 implementation.
+- Child-list widgets explicitly enforce their nested queries on RC.5; the generic renderer
+  otherwise bypasses field locks inside the already-authorized widget action scope.
+- MASKED-user response scanning and Quick Search indexing are not available on the pinned RC.5
+  test classpath. FULL and actual HIDDEN-field-lock scans run now; no simulated masking is used.
