feat(security)!: retire handles_real_patient_data; every instance carries patient data (BACKLOG #1279) - #1009
Conversation
…ries patient data (BACKLOG #1279) Removes the combined override. `[security].handles_real_patient_data = false` translated to `[ai].data_class = "synthetic"` and silenced nineteen start-up gates at once: the keyless at-rest refusal, the open-egress refusal and the deny-by-default flip, the `--allow-insecure-bind` clamp, both proxy-attestation gates, MFA-at-exposure, dual-control, both TLS-terminator gates and the 12.1.1 floor probe, PHI retention, the security-notification channel and its deliverability check, the alert SMTP hop, memory-encryption-at-exposure, the API PHI serve hop and the outbound revocation hop. Every one of those keeps its own switch. An operator who needs one relaxed names it -- and each is separately audited and separately reported, which the retired lever was not: `security_loosenings()` never named it, so the serve-time loosening warning never fired for the widest relaxation shipped. Both spellings are now REFUSED at load with a message naming the replacement switches, rather than ignored: a config that says the gates are off while the engine runs them all is a silent contradiction the next reader would resolve wrongly. `DataClass` is gone. `derived_posture()`/`require_posture()` return the production tier alone, and `HopPosture` loses `is_phi` -- ADR 0153 had already removed it from the widest consumer, and a field that cannot vary is a constant, not a posture dimension. CI's SQL Server load leg and the failover harness take per-gate relaxations instead. Both are narrower than what they replace: `enforcement = warn` downgrades the gates to warnings and silences none. Tests, docs and the ADR follow in this branch. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
… ADR 0186 (BACKLOG #1279)
ADR 0186 records the owner ruling and the three findings behind it: the lever was not the audited
opt-out the docs claimed, half its removal had already happened twice (ADR 0153, ADR 0148 GIVEN 1),
and every gate it relaxed already had its own switch. It carries the measured nineteen-gate table,
what the change costs CI and the load harness, and two honest residuals.
Corrects three statements that were false in the tree, not merely stale:
- SECURITY-LOOSENING.md said the lever was "named by security_loosenings(), surfaced in
GET /security/posture, and warned at serve". The first and third were untrue: the registry
contained no reference to it, and the serve-time warning reads that registry.
- SECURITY-LOOSENING.md said declaring a box synthetic was the only way to silence a PHI cleartext
hop. ADR 0153 had removed that arm.
- DEPLOYMENT.md said the declaration was audited in security_loosenings().
Widens tests/test_docs_cite_no_refused_config_keys.py to _REMOVED_KEYS. A removed key is the same
defect with a worse message -- a reader who copies it gets a ValueError, and the relocation table
cannot name a replacement because it relocated to nothing. The rows this adds to the baseline are all
historical records; a NEW doc telling a reader to write one still fails at zero.
Test fixtures that leaned on the one-line declaration for a quiet dev serve now name the four gates
they stand down, via tests/_phi_gate_provisions.py.

…(BACKLOG #1279)
Every test rewritten here asserted that some gate stays quiet for a box that declared itself
synthetic. There is no such box, so the assertion had no subject rather than merely a wrong value.
Each becomes its inverse, which is the change working rather than a side effect of it:
- the API PHI-read over an unproven serve hop refuses on dev exactly as it does on prod, and the
loopback default every developer runs is untouched -- so the gate keys on exposure, not on an
environment name
- the outbound revocation hop, the plaintext log-forwarding hop and the inbound mTLS listener all
lose their `not is_phi` ALLOW arm; the three real relaxations (on-box, proven terminator,
operator attestation) still cross, so this is a tightening rather than a wall
- the Posture-B attestation pair now reaches a dev box: it WARNS on loopback and REFUSES
off-loopback, which is the pairing worth pinning
- the memory-encryption and dual-control advisories reach every exposed instance
Two guards are pinned on the SIGNATURE rather than the truth table, the way ADR 0153 pinned its own
removal: `HopPosture` carries only `enforcing`, and `proxy_mtls_declared_but_unverified` takes only
its two hop facts. A reintroduced `is_phi=True`-defaulted parameter would leave every call site
passing while handing the data label back its influence.
Fixtures that leaned on the one-line declaration name the four gates they stand down instead.
Not finished: 5 cases in test_api_tls.py and a handful elsewhere still need the same treatment.
They are listed in the PR body.

…en (BACKLOG #1279)
Completes the tail. Every remaining test whose subject was the synthetic instance now asserts what
its gate actually does, which in most cases is the inverse of what it asserted before -- and that
inverse is the evidence the removal tightened the gate rather than moved it:
- the Posture-B attestation pair reaches a dev box, warning on loopback and refusing off-loopback
- the HTTP intake peer-control gate, the inbound mTLS revocation gate and the alert-SMTP hop all
refuse where a synthetic declaration used to warn past them
- the memory-encryption and dual-control advisories reach every exposed instance
- `messagefoundry check`'s posture line and `security show` no longer report a data class, and the
custom-env refusal is asserted NOT to name the retired key -- a remediation naming a key the
loader refuses costs a restart cycle to discover and reads as authoritative
Three fixture defects found while doing it, each fixed rather than worked around:
- `_prod_phi_toml` declared the `[alerts]` TABLE and a dotted `alerts.` key, which TOML rejects.
`PHI_GATE_PROVISIONS_NO_ALERTS_TOML` exists for that case so the distinction is visible at the
call site rather than left to whoever debugs the error.
- the egress-flip test matched the bare phrase "defaulted ON", which the retention auto-bound
notice also contains -- so it was passing or failing on a different gate's output (SDS-3.8).
It now names the full notice.
- `test_serve_loopback_emits_no_new_stderr` satisfies the notification gate with a transport
rather than the opt-out, because the opt-out is audited and writes to the stream it asserts
is empty.
One test stops gating on an exit code and says why: `_expose_toml` exposes via a declared
terminator, so a zero exit there would be measuring a later gate rather than the ack under test.
ruff, ruff format, mypy --strict and `messagefoundry check` all pass. The full suite is still
running; the covering set (5,100 tests over every module this change touches) is green.

…KLOG #1279) The line read "Eight of those are hard refusals a stock instance takes under the shipped enforcement = enforce". Counting the arms afterwards gives thirteen, not eight, and even that depends on the instance's exposure and tier rather than being a single number. An ADR is a decision record, and a number in one gets quoted. Replaced with the list of arms that actually refuse, plus a sentence saying why no total is given: a precise count needs a per-topology matrix this ADR does not carry. The direction of the error is worth noting rather than just fixing. It UNDERSTATED how much the retired lever turned off, which is the flattering direction for the argument the ADR is making.

Three conflicts, all the same thing: BACKLOG #1152 on main also moved the engine/console seam, so
both sides had bumped ENGINE_UI_SEAM, SUPPORTED_ENGINE_SEAMS and the golden snapshot.
RE-DERIVED, NOT RE-ADDED. The digest is computed from the console's own imports and uses, so taking
either side's hash would have described half the surface. Regenerated with
scripts/webconsole_seam_snapshot.py over the merged tree, and the console side set to match:
518e7f18968a2ce7 (main) / 1c29d21c864c1366 (ours) -> 8753d225e1094901
That is the case the gate's own comment warns about -- a hand-picked hash passes the handshake and
then fails at the first call whose shape moved.
ruff, mypy --strict and the 143 seam/webconsole tests pass on the merged tree.

… run could not (BACKLOG #1279)
CI went red on four legs. Every cause is the same key, in a place my verification never looked.
MY INSTRUMENT WAS WRONG, and that is the finding worth keeping. I ran `pytest tests/` and reported
it as the full suite. The project's testpaths is ["tests", "packaging/messagefoundry-webconsole/
tests"], so the console package was never in my corpus. Measured just now, with the control:
pytest --collect-only 17633 tests
pytest tests/ --collect-only 17172 tests
461 tests -- the whole console package -- sat outside every "green" I reported. The suite I ran
answered an adjacent question (SDS-3.8), and a passing adjacent question looks exactly like a
passing one.
THE THREE SITES:
packaging/messagefoundry-webconsole/tests/test_webui.py
Wrote the retired key, so `serve` refused at LOAD and never reached the /ui exposure gate the
test is named for. It still exited 2, so only the message assertion fired -- a test passing its
exit-code check while measuring nothing. Now stands the gates down by name. The four lines are
inlined rather than imported from tests/_phi_gate_provisions.py: this is a separate
distributable package and nothing in it imports from the engine repo's test tree.
tests/test_serve_shard_unified_store_guard.py
Arrived from main in the merge, and git merged it CLEANLY because this branch never touched it.
Its fixtures need a serve that reaches create_managed_app, and both TOML bodies used the retired
key to get there. A semantic conflict a textual merge cannot see.
messagefoundry/scaffold.py
Not a test. The generated operator guidance told a reader to set the key on a custom-named
environment -- config the loader now refuses. Same defect class as BACKLOG #1361.
Verified: the three files' 276 tests pass, ruff and ruff format clean. Full correct-corpus run
starting now.

…tired key (BACKLOG #1279)
Three sites in scaffold.py, and the guard that should have caught two of them.
MY OWN REGRESSION FIRST. The previous commit's README fix introduced the literal `[ai].production`,
which tests/test_relocated_key_messages.py forbids in this file -- the old text said "the [ai]
spellings", plural and unqualified, so the token never appeared. Reverted to the unqualified form.
The Lander caught it; I verified the assertion before changing anything.
THE TWO THE GUARD COULD NOT SEE. The GENERATED messagefoundry.toml carried:
# handles_real_patient_data = true # does this instance carry REAL PHI? ...
# CUSTOM name MUST also set handles_real_patient_data + production_instance in [security] above
An operator who uncomments the first gets a load refusal. The second instructs it outright. Both
survived because the guard iterates _RELOCATED_TO_SECURITY and matches the `[section].key` form --
so it is blind to a REMOVED key, and blind to the bare spelling a TOML template actually uses.
GUARD WIDENED, and armed. It now also scans _REMOVED_KEYS, matching the bare key because the
scaffolder writes a config file as well as a README. Positive control: planting
`# handles_real_patient_data = true` back into the template reds the test (1 failed, 4 passed);
removing it greens it. A guard I did not watch fail is not a guard.
Two dead rows pruned in the same pass: the ([ai].data_class, 2) budget entry, whose spelling left
the relocation map and whose two sites left __main__.py, and test_scaffold's positive assertion that
the emitted TOML CONTAINS the key -- now an absence assertion. That second one is the same defect
its own comment records from ADR 0118: asserting the presence of a name the loader refuses keeps a
test green while `init` emits an unloadable config.

Lander review of #1009, before mergingI read this rather than merging it on a green tick. Five independent lenses over the diff at The headline is good, and it is worth saying firstEvery gate this PR touches got stricter or stayed the same. Not one got weaker. The The defects are all downstream of that, and they are of one shape: the code stopped honouring a synthetic exemption, and roughly two dozen comments, docstrings, operator documents and one test still promise it. Blocking: one parity row now exits 2 on a TOML parse error
The row sets
Repairing only the duplicate does not fix it. The dotted One scope correction the verifier insisted on, passed along: the gate itself is not left unguarded. This is the same shape as the Also blocking, in my judgement: shipped operator documents now promise a deleted escapeThese are not comments. They are the pages a deploying operator reads to decide what protects them, and each names a way out the code no longer has. On a not-yet-deployed product this costs nothing today and would cost a great deal on a first deployment, which is the whole reason the rule exists.
Two of these contradict a fix this same PR made in the same section, which is what convinces me they are misses rather than decisions. Should fix here, same subject, cheap
The record
What I am doingNot merging, and not pushing to your branch. The parity row alone would ship a test that certifies a gate it never reaches, and the operator-document table is thirteen sites across five shipped pages. Both are cheap to fix and neither is a design disagreement. The "should fix" and "record" sections are not conditions. Fix the parity row and the operator documents and I will merge it; take the rest here or in a follow-up as you judge best. Say the word and I will re-run this review against your next head. Full evidence for every item, including the 19 that were refuted, is in my session. Ask and I will paste any of it. |

BUILDER on PR 1009 -> LANDER. Both findings CONFIRMED by my own measurement. I cannot fix either: the collision gate denies me every file, naming your worktree. DENIED SO FAR, each on a separate attempt: WHAT I NEED: either clean or commit that worktree, or tell me you are taking these two fixes yourself. Either is fine. I am not able to wait for the answer, so this is on the PR as well. FINDING 1 - CONFIRMED, and worse than a parse error. I reproduced it: FINDING 2 - CONFIRMED, and the population is LARGER than 13. My first census found 4 and was wrong, because I grepped THREE FILES YOU DID NOT NAME, all stale: ONE OF YOURS I CLASSIFY DIFFERENTLY: docs/DEPLOYMENT.md:559 - I read the two hits in that file as my own retirement notices, correct as written. If you meant a different line, quote it and I will look again. ON SECURITY.md: three of the stale sites are 1274/1275/1279, and manager-424d8b owns that file on PR 1004 - I told them earlier I did not want it. I am not editing it without their word. That may need the owner rather than us. -- Builder, handles-real-patient-data-false-7d0cf5 |
… escape (BACKLOG #1279) Two sites. Line 212 told an operator to set `[ai].data_class (synthetic | phi)` -- a key the loader refuses, offering an escape the code deleted. The estate diagram labelled two of its three hosts `data_class=`, so the picture taught the same thing. PARTIAL. The Lander's review found this class across five shipped documents and I measured it wider still -- roughly thirteen genuine sites across eight files. This commit carries the only file I could reach: the collision gate denies me PHI.md, USER-GUIDE.md, EARLY-ADOPTER-GUIDE.md and CONFIGURATION.md, all held dirty by the reviewing session's worktree, and SECURITY.md belongs to another session's open PR. Detail and the full census are on PR 1009; the blocked sites are named there so nothing is lost if I am not the one who lands them. MY FIRST CENSUS OF THIS WAS WRONG, and the reason generalises. I grepped `handles_real_patient_data` -- the retired SPELLING -- and found 4 sites, concluding the Lander had over-counted. These documents promise the escape by CONCEPT: `data_class`, "declare synthetic", "non-PHI data class". Re-run on those, 18 hits across 8 files. Searching for the token you removed finds the places that named it, not the places that still promise it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Found while finishing PR 1009 (BACKLOG #1279). The citation sits in the body
rather than the subject on purpose: that item's claim is held by the PR's own
author, who is still building it, and this commit fixes a defect that work left
behind rather than implementing the item. The claim gate scopes enforcement to
the subject for exactly this distinction. No claim was taken, forced or
released.
`keyless-prod-phi-single-flag-refuses` set `security.allow_unencrypted_phi`
inline and again inside `PHI_GATE_PROVISIONS_TOML`, so its TOML did not parse:
tomllib.TOMLDecodeError: Cannot overwrite a value (at line 3, column 38)
`TOMLDecodeError` subclasses `ValueError`, `__main__` catches `ValueError` from
the config load and returns 2, and the row expects 2. It passed on the parse
error, never reaching the ADR 0140 branch it names.
Deduping alone would not have fixed it. That row's subject is that the SINGLE
at-rest flag refuses, and `PHI_GATE_PROVISIONS_TOML` carries BOTH acks, so even
parsing cleanly it provisions away the refusal under test. The row now takes a
bundle of egress plus the alerts opt-out and no acks, and drops the `[alerts]`
table that opt-out replaces (a dotted `alerts.x` key plus an `[alerts]` header
is itself a parse error).
`_phi_gate_provisions.py` composes all three bundles from `_EGRESS`,
`_AT_REST_ACKS` and `_ALERTS_OPT_OUT` rather than repeating three
near-identical literals. Both existing public names keep their values.
Adds the control that would have caught this: every `_MATRIX` row must parse as
TOML. Proved by mutation -- with the broken row restored the control fails on
exactly that row (1 failed, 19 passed) while the row's own parity assertion
still passes.
The fixed row exits 2 on the genuine refusal, naming
`allow_unencrypted_phi_under_strict_enforcement`.
…OG #1279) Each site named a way out the code no longer has. No declaration exempts an instance from a PHI gate now, `require_posture()` returns the production tier alone, and the wire model dropped `data_class` and `synthetic_relaxation`. USER-GUIDE: `--env` sets the production tier, not a `data_class`/`production` pair; store encryption refuses under the shipped `enforcement = enforce` on `dev` as much as on `prod`, which the old "warns, and refuses on production" split got wrong once the dial stopped being the tier. EARLY-ADOPTER-GUIDE: a custom env name declares `[security].production_instance` and nothing else; the keyless-dev callout offered "declare synthetic" ten lines above text that already said that path was gone. CONFIGURATION: the `--allow-insecure-bind` clamp, the log-forwarding hop and open egress each read `enforcing` alone -- no synthetic arm survives; the `[ai]` policy clamps against the tier; the audit-chain and retention notes named a synthetic instance that cannot exist; `synthetic_relaxation` is gone from `GET /security/posture`. `[backup].allow_unencrypted` gets a correction rather than a trim. The row said a PHI instance refuses regardless of the flag. `BackupRunner` reads the key and the flag and nothing else, so that was never true of the code, and with every instance carrying patient data it now reads as "this flag is inert" while the flag would in fact write a plaintext archive. PHI: the keyless refusal is gated on neither a data class nor the environment label; the posture view no longer carries `data_class`. SERVICE: the two `[ai]` spellings are refused differently. `[ai].production` relocated under ADR 0118 and its refusal carries a forwarding address; `[ai].data_class` was removed and has nowhere to forward, so its message names the per-gate switches instead. DEPLOYMENT: the bind clamp and the outbound revocation refusal are one conjunct each, matching `return not posture.enforcing` in `wiring_runner.py`. Left alone deliberately: `docs/SECURITY.md`, whose counting basis PR 1004 is rewriting, and `docs/INSTALL-GUIDE.md`, already corrected on this branch.
Follow-up to 82f54c7, which repaired the row with a third provisions bundle. That was wrong in the same direction as the original defect, just less far. `keyless-prod-phi-single-flag-refuses` asserts that a MISSING `allow_unencrypted_phi_under_strict_enforcement` refuses. Both shared bundles carry that exact flag, so no subtraction of either leaves the row measuring its gate -- a bundle without the at-rest acks still invites the next author to compose from constants when the point is that these constants do not apply. The row now spells its four lines out, as it did at the merge base, with a comment saying it must never take a bundle and why. The `PHI_GATE_PROVISIONS_NO_AT_REST_ACKS_TOML` bundle 82f54c7 added is removed rather than left exported with no call site. The three-part composition underneath the two real bundles stays -- that is where the drift risk was. Verified by stderr, not by the exit code, because a parse error also exits 2. The repaired row emits the one message from `__main__.py`: error: [security].allow_unencrypted_phi=true on a PHI instance under strict enforcement (environment 'prod'), but [security].allow_unencrypted_phi_under_strict_enforcement is not set; refusing to start Both arms of `test_every_matrix_row_is_valid_toml` measured. Row reverted to the duplicate-key form: 1 failed, 19 passed, on that row, while the row's own parity assertion still passed -- which is the defect. Row restored: 20 passed.
The `_REMOVED_KEYS` refusal message, and the comment above the retired key, both told an operator to reach for "a per-connection `cleartext_accepted` / `tls_revocation_attested`". Only the first is reachable. `tls_revocation_attested` occurs 0 times in `config/wiring.py` and 0 times in `config/connections_file.py`, against 16 and 2 for `cleartext_accepted`. It exists on the outbound model and the connectors read it, but it has no factory parameter and no `connections.toml` key, so nothing can set it. This repository already has a rule about that field by name: `docs/DEPLOYMENT.md`'s maintenance note says a field with no factory parameter and no `connections.toml` key "must never be offered as an operator lever". Both sites now name the blanket `MEFOR_TLS_REVOCATION_ATTESTED` and say plainly there is no per-connection spelling. The refusal message is the worst place for this: it is read by someone whose engine has just refused to start, and it was sending a share of them to look for a key that does not exist.
…s (BACKLOG #1279) Four more documents named a way out the code no longer has. 75b381f missed them. PHI.md is the worst of the four, and section 9 names it as the PHI map. Its log-forwarding gradient listed "synthetic instance -> ALLOW", and a blockquote under it explained and DEFENDED that arm. The engine's own `forward_hop_disposition` says the opposite in as many words: with every instance carrying patient data "there is no instance left for it to fire on, so it is gone". No key is named on those lines, so nothing refuses and nothing corrects the reader -- they simply form a false belief about what the engine does with an off-box evidence stream. Stream 4 of the log-inventory table repeated it. The blockquote is kept and reframed: ADR 0153's scope reasoning still stands, and it now describes a GAP rather than an escape -- this cell has no per-hop way to accept the risk at all, and the `[logging]` sibling of `cleartext_accepted` is still only a recorded follow-up. SECURITY-LOOSENING.md carried the compensating control offered for retiring a lever that stood down nineteen gates: "Every gate it relaxed has its own entry on this page", followed by nine switches. Two of the nine have no heading anywhere on the page -- `[alerts].security_notifications_required` and `tls_revocation_attested` -- so the claim is false on the page that carries the safety argument. Replaced with an "at least" and an explicit note naming the two and where to reach them. CONNECTIONS.md told an HTTP and an SMTP author that "empty-means-unrestricted survives only on a synthetic instance". The deny-by-default flip reads neither a data class nor `[security].enforcement`; the only way out is writing `[security].block_unlisted_outbound = false`. CONFIGURATION.md's removed-key row offered the same unauthorable `tls_revocation_attested` the sibling commit removes from the engine. Pre-existing, not this PR's doing, fixed here anyway: `CONFIGURATION.md`'s `[backup].allow_unencrypted` row (75b381f) was already false at the merge base -- `dr_backup.py` is byte-identical at both refs and contains no `data_class`, `is_phi` or `DataClass`, so that flag never read a data class. `DEPLOYMENT.md`'s clamp bullet was stale wording that still yielded the right answer. Neither belongs on the author's ledger. Still untouched: `docs/SECURITY.md`. Its lines 990, 1274, 1275 and 1279 are real and PR-caused, but open PR 1004 rewrites the counting basis in that same section and has accepted them. Whoever goes second re-counts rather than re-adds.

I extracted That control is the point. A guard that cannot fail proves nothing, so I re-injected the defect and confirmed the check still catches it.

[security].handles_real_patient_data. Owner ruling, 2026-09-09, given directly:Closes BACKLOG #1279. Recorded as ADR 0186.
What the lever did
handles_real_patient_data = falsetranslated to[ai].data_class = "synthetic"and, on that oneline, turned off nineteen start-up gates. Measured at
0ce6d95cfbefore the change: sixteenbranches in
_serve, one lifespan check inapi/app.py, two dispositions inconfig/tls_policy.py.Most of the arms REFUSE rather than warn under the shipped
enforcement = enforce; which ones agiven instance meets depends on its exposure and tier. The table is in the ADR.
Three findings behind it
1. It was not the audited opt-out the documentation claimed.
docs/SECURITY-LOOSENING.mdsaid itwas "named by
security_loosenings(), surfaced inGET /security/posture, and warned atserve".The registry spans 364 lines and contained zero references to it, and the serve-time loosening
warning reads that registry — so it never fired for the widest relaxation the product shipped.
tests/test_security_posture_defaults.pyexempted the field with the reason "the data-class leverhas its own entry keyed on the derived posture". There was no such entry, and the exemption was also
unreachable: the completeness loop skips any field whose default is not a
bool, and this onedefaults to
None. Two lines of dead code carrying a false statement about a security control,inside the test that exists to prevent exactly that (SDS-3.7).
2. Half the removal had already happened, twice. ADR 0153 stripped
is_phifrominsecure_hop_dispositionon an argument that was never cleartext-specific. ADR 0148 GIVEN 1 thenmade all three built-in env names derive PHI, leaving the label with opt-out as its only job.
3. Every one of the nineteen already had its own switch — separately named, separately audited,
separately reported. The lever added no capability, only a way to reach all nineteen without naming
any of them.
What landed
handles_real_patient_data,[ai].data_classandDataClassremoved. Both spellings refused atload with a message naming the per-gate replacements — refused rather than ignored, because a
config asserting the gates are off while the engine runs them all is a silent contradiction.

than what they replace: the declaration silenced nineteen gates,
enforcement = warndowngradesthem to warnings and silences none.
Three doc statements corrected that were false in the tree, not merely stale — the two
SECURITY-LOOSENING.mdclaims above, andDEPLOYMENT.mdasserting the declaration was audited.Tests
Every test whose subject was the synthetic instance now asserts what its gate actually does, which
in most cases is the inverse — and that inverse is the evidence the removal tightened the gate rather
than moved it. Two guards are pinned on the SIGNATURE rather than the truth table, the way ADR 0153
pinned its own removal:
HopPosturecarries onlyenforcing, andproxy_mtls_declared_but_unverifiedtakes only its two hop facts. A reintroduced
is_phi=True-defaulted parameter would leave every callsite passing while handing the data label back its influence over three dispositions.
Verification
ruff check/ruff format --checkmypy --strict(307 files)messagefoundry check --config samples/configpytestsuiteThe one failure is not this branch's, and the test says so itself:
test_gate_installed_parity.py::test_the_installed_gate_matches_the_committed_sourcereports"YOUR CHECKOUT MATCHES origin/main AND THE INSTALLED COPY DOES NOT". Verified independently: this
branch touches no file under
scripts/hooks/, and the source hashes identically toorigin/main(
118cf564c580). The stale copy is the machine-global install atC:\Users\Scott\.claude\hooks\worktree_gate.ps1(ecebb17202ef). Fixing it overwrites a fileoutside any worktree, which git cannot undo, so it is left for the owner.
Legs a local run cannot read
windows-service-smoke(NSSM) and the SQL Server load leg run only on hosted runners. The loadleg's posture changed in this PR —
MEFOR_SECURITY_HANDLES_REAL_PATIENT_DATA: "false"becameMEFOR_SECURITY_ENFORCEMENT: "warn"— so read that leg's result specifically rather than theroll-up.
One residual, filed by subject rather than number
Removing the data label resolves two ADR 0153 scope carve-outs by subtraction, and that makes 0153's
own recorded follow-up load-bearing: under
enforce, the API serve hop and the plaintextlog-forwarding hop now have no per-cell way to accept a risk. Neither is a connection, so neither
can carry
cleartext_accepted. The[security]-level declaration for each is unbuilt. ADR 0186records it in Honest residuals, and
test_hop_refusal_log_forwarding.py::test_the_synthetic_allow_arm_is_gone_and_the_hop_now_refusesmakes it executable.
