-One command to run all web environments:
+After fetching assets and building the local image, start all web environments with an explicit control-plane token:
 
 ```bash
-docker run -p 8101:8101 -p 40000-40023:40000-40023 battalion7244/webharbor:latest

+docker run -e WEBSYN_CONTROL_TOKEN -p 8101:8101 -p 40000-40024:40000-40024 webharbor:dev
 ```
 
-Then point your agent at `http://localhost:40000` through `http://localhost:40023` to explore 24 local mirrors of WebVoyager sites: `Allrecipes, Amazon, Apple, ArXiv, BBC News, Booking, GitHub, Google Flights, Google Maps, Google Search, Hugging Face, Wolfram Alpha, Cambridge Dictionary, Coursera, ESPN, Merriam-Webster, IKEA, Phys.org, Target, TED, Ohio State University, Rotten Tomatoes, Compass, and Walmart Careers`.
+The fetch and build paths verify the immutable HF revision, every archive size and SHA-256, and the extracted managed-tree digest against tracked `assets-manifest.json`; Docker dependencies are installed from exact versions and wheel SHA-256 values in `requirements.lock`.

-WebHarbor must already be running locally (`docker run -p 8101:8101 -p 40000-40023:40000-40023 battalion7244/webharbor:latest`).
+WebHarbor must already be running locally. For agent tasks that do not call the control plane, expose only the site ports from a locally built image: `docker run -p 40000-40024:40000-40024 webharbor:dev`. If you expose `8101`, set `WEBSYN_CONTROL_TOKEN` and send it as a bearer token as documented in the root README.

+# PR 71 Final Audit
+
+## Status
+
+Release candidate validated against original PR head `73eba14579449404abf1efd5cc6b86c7b5507a7a` and upstream `main` `36004932bdf82afbe36dc14e00f66841eccf9946`. The integrated topology has 25 sites; Drugs.com is appended at container port `40024` without changing the existing site positions.
+
+This audit did not post a GitHub comment and does not authorize merging the upstream pull request.
+
+## Review Streams
+
+### Reviewer 1 — security, authentication, authorization, and state integrity
+
+- **Observation:** The original control plane allowed unauthenticated reset/restart operations. Session secrets, login controls, input bounds, transaction behavior, account ownership, anonymous review voting, and SQLite constraints also required review.
+- **Verification:** Direct source inspection confirmed public mutation routes in `control_server.py`, process-local concurrency assumptions, anonymous vote-ledger growth, registration commit ordering, weak nullability, and session-cookie data exposure.
+- **Remediation:** Every control endpoint now requires a constant-time bearer-token check. Drugs.com has a cryptographically random runtime secret, bounded requests and fields, CSRF on mutations, strict safe redirects, login throttling, a bounded runtime account count, unique site-specific cookie names, optional secure cookies for TLS deployments, authenticated-only bounded helpful votes, ownership-scoped mutations, non-null/check/unique/FK constraints, and an exclusive per-database process lock. Anonymous email and medication-browsing history are not stored in the client cookie.
+- **Evidence:** `sites/drugs_com/tests/test_app.py`; authenticated and unauthenticated control-plane tests in `sites/drugs_com/tests/test_integration.py`; final Drugs.com suite: 406 passed.
+
+### Reviewer 2 — application behavior and data consistency
+
+- **Observation:** The original application inferred dosage forms, pregnancy guidance, warnings, storage, overdose behavior, lifestyle interactions, availability, clinical conclusions, and class-wide facts from names or broad classes. Ranitidine, haloperidol, and Janumet records were internally inconsistent.
+- **Verification:** Each reported example was checked against `DRUGS_DATA`, `DRUG_CONTENT_OVERRIDES`, route handlers, templates, and generated SQLite rows.
+- **Remediation:** Missing drug-specific fields now render explicit empty states; class/name-derived clinical fallback generation was removed. Lifestyle rows are keyed to explicit generic names, absent interaction coverage is reported as `unrepresented_pairs`, and the three inconsistent catalog records were corrected. Drug/class/condition/price/pregnancy/symptom/news pages now distinguish raw or simulated fixture fields from medical or regulatory facts.
+- **Evidence:** Exact static catalog digest `0048909eebc40a017c99cdc08f4fab89760035bc5bcbc476c5fb3a7da4049d9f`; application and seed tests; 21 browser task workflows.
+
+### Reviewer 3 — task feasibility and database-grounded truth
+
+- **Observation:** The original 21 tasks had inconsistent ports, direct answer leakage, ambiguous workflow requirements, and several verifier/task mismatches.
+- **Verification:** Every task was solved from the canonical initial database and through the rendered browser UI. Required entities, result order, credentials, and dedicated subpages were inspected.
+- **Remediation:** All task origins are `http://localhost:40024/`; rubric text contains no literal answer; task wording and dedicated FAQ/warnings/dosage workflows are aligned; canonical truth is loaded only from the protected initial snapshot.
+- **Evidence:** `sites/drugs_com/tasks.jsonl`; final 21/21 real-browser run with 99 successful UI steps.
+
+### Reviewer 4 — adversarial verifier review
+
+- **Observation:** The original verifiers accepted fabricated origins, `inspect`-only trajectories, blank screenshots, loose final-URL shortcuts, negated or numerically reassociated answers, wrong entity associations, and incorrect Task 13 pairings.
+- **Verification:** Adversarial fixtures reproduced wrong-origin, shortcut, contradiction, extra-entity, wrong-credential, malformed-PNG, schema mutation, row mutation, number-binding, and pair-swapping false positives.
+- **Remediation:** Verifiers now require the exact task ID and `localhost:40024` origin, successful supported browser actions, ordered UI transitions, exact input multisets, decoded nonblank PNG sequences with visual transitions, a final `done` action bound to the answer, canonical initial seed SHA-256, exact schema/table/row/byte equality, task-specific entity and numeric binding, explicit contradiction checks, domain exclusivity, and exact ordered drug/imprint pair segments.
+- **Evidence:** 274 positive and adversarial verifier cases are included in the 406-test Drugs.com suite; final real-browser run passes all 21 entry points. The verifier trusts the browser harness to write `action_result`; it does not claim a cryptographic attestation against a process that can arbitrarily rewrite the complete run directory.
+
+### Reviewer 5 — UI, responsive behavior, accessibility, and progressive enhancement
+
+- **Observation:** The original UI had document-level overflow at narrow widths, clipped navigation, non-keyboard autocomplete behavior, ambiguous controls, missing table scroll regions, sticky hash-target occlusion, and JavaScript-only review/notes/checker/price workflows.
+- **Verification:** Routes were exercised at 320, 360, 375, 390, 768, 1024, 1280, and 1440 CSS pixels, including authenticated pages and representative parameters. Keyboard More-menu and hash-target checks were run at every width.
+- **Remediation:** Responsive containment, table regions with keyboard focus, non-sticky mobile header behavior, scroll offsets, native disclosure navigation, labeled controls, listbox/combobox state, skip/focus styles, reduced-motion behavior, native review rating selection, no-JavaScript notes and interaction forms, all-quantity no-JavaScript price rendering, and explicit unsupported Pro workflows were implemented.
+- **Evidence:** 464 final route/viewport checks: 0 HTTP failures, 0 document overflow, 0 empty-content failures, 0 broken images, 0 duplicate IDs, 0 unnamed controls, 0 empty links, 0 missing alt attributes, 0 page/console errors, 0 remote requests, 0 menu failures, and 0 hash-target failures. Twelve no-JavaScript workflows passed.
+
+### Reviewer 6 — current-main, Docker, control plane, and Hugging Face integration
+
+- **Observation:** The original branch targeted an obsolete site count and port, used a stale asset revision, and had no final Docker artifact or robust reset evidence.
+- **Verification:** The 25-site order was compared across `websyn_start.sh`, `control_server.py`, Docker, docs, task manifests, and current main. The pinned HF revision and archive set were fetched from scratch.
+- **Remediation:** Drugs.com is site 25 at `40024`; `.assets-revision` pins immutable HF commit `18e64e4d230794f990199f3327432d26db36866f`; fetch validates the exact archive-name set and site-aware seed requirements; Docker performs a final 25-database integrity gate; control reset uses staging/rename and treats backup cleanup outside rollback; reset-all returns structured partial results.
+- **Evidence:** Fresh 25-archive fetch/check passed. Drugs.com archive: 134 bytes, SHA-256 `fa2092873de0d2a06c2ecac5fd389a8863ab3e271b9c197f9c3dd5fa984f378b`. The no-cache image build passed its 25-seed gate; the post-commit image digest is recorded in the external completion packet to avoid a self-referential tracked artifact.
+
+### Reviewer 7 — tests, evidence, and repository hygiene
+
+- **Observation:** The original branch lacked adequate app/verifier tests, had lint failures, carried unaudited generated artifacts, and had incomplete conflict/hygiene checks.
+- **Verification:** Tests, ignored/managed paths, generated seeds, syntax, Ruff E9/F, merge markers, and main-relative diff whitespace were checked from the actual worktree.
+- **Remediation:** Application, seed, integration, provenance, reset failure-injection, archive failure-injection, and verifier adversarial suites were added. Build/runtime test files are excluded from the image. Managed-path parity is tested across `.assetpaths`, `.gitignore`, and extraction scripts.
+- **Evidence:** Ruff E9/F passed; Python compile passed; shell syntax passed; `git diff ... --check` passed; no conflict markers, symlinks, AppleDouble files, or tracked Drugs.com image files were found.
+
+### Reviewer 8 — provenance, medical-content presentation, and compliance
+
+- **Observation:** The original archive included 43 JPEG files without per-file source/license evidence and Apple metadata. Templates presented simulated reviews/news, professional identities, official service channels, current approvals, prices, clinical claims, and generated pill graphics as real.
+- **Verification:** Archive members, xattrs, templates, tracked source declarations, runtime requests, and each content family were inspected.
+- **Remediation:** Unverifiable JPEGs were removed. `asset_inventory.json` requires zero runtime media files. `content_inventory.json` records the source location and unresolved external provenance of every fixture family. Synthetic pill diagrams are visibly labeled and cannot be presented as photos or identification evidence. Simulated articles/reviews, generated prices, raw medical text fixtures, local support forms, subscriptions, and professional layouts are labeled at their point of use. Missing data is not synthesized into drug-specific claims.
+- **Evidence:** Runtime performs zero background external requests in the responsive matrix. The repository contains zero tracked Drugs.com image files and zero AppleDouble files. This candidate intentionally does not claim real-site pill-image fidelity because PR 71 supplied no auditable source/license mapping.
+
+### Reviewer 9 — remediated security/application completion review
+
+- **Observation:** The first remediation still treated missing interaction coverage as no interaction, applied broad class lifestyle rules, accepted count-preserving seed tampering, destroyed the old seed before build success, allowed ambiguous brand wildcards, had nullable/default inconsistencies, and committed registration before vote claiming.
+- **Verification:** Each objective example in the second-round report was reproduced or traced to exact source and database rows.
+- **Remediation:** Unknown coverage, explicit generic lifestyle rules, manifest-bound static catalog/schema digests, failure-atomic staged seed generation, exclusive DB ownership, exact brand-element lookup, corrected nullability/defaults, authenticated voting, and a single registration transaction close these items.
+- **Evidence:** Tampered static content makes `/_health` return 503; import and seed failure tests preserve known-good state; a second process sharing the SQLite path fails closed; all regression tests pass.
+
+### Reviewer 10 — remediated task/verifier completion review
+
+- **Observation:** The first verifier rewrite still accepted wrong localhost ports, decoy login credentials, final-URL shortcuts, mixed contradictions, unbound numbers, extra entities, weak risk overlap, and unpaired Task 13 output.
+- **Verification:** All listed objective adversarial cases were added as tests, including natural valid number phrasing and verbose valid pairs to prevent false negatives.
+- **Remediation:** Exact-origin, successful action protocol, ordered input/click transitions, exact answer domains, bound numeric forms, curated risk concept groups, exact Alice medication set, and delimiter-based ordered pair checks were added.
+- **Evidence:** Final verifier suite and 21 real browser trajectories pass; all requested adversarial cases fail.
+
+### Reviewer 11 — remediated UI/compliance completion review
+
+- **Observation:** The first UI remediation retained official/clinical/commercial claims, inferred dosage/warning/pregnancy/image content, incomplete no-JavaScript workflows, mobile clipping, raw status fallbacks, and ARIA issues.
+- **Verification:** Every cited template and CSS selector was inspected, then all affected workflows were re-exercised after restart.
+- **Remediation:** Official identities/channels, unverified clinical generation, fake current news/approvals, redeemable-price language, no-image pill fallback, raw status assertions, and unsupported workflows were removed or explicitly represented as fixtures/empty states. Responsive and accessibility defects were closed.
+- **Evidence:** Final 464-check responsive/accessibility matrix and twelve no-JavaScript workflows pass with zero listed failures.
+
+### Reviewer 12 — remediated integration/test completion review
+
+- **Observation:** The first integration remediation lacked a clean image, could roll back from partially deleted backups, weakly validated arbitrary seed directories, accepted wrong archive sets and media-only ordinary archives, returned unstructured reset-all failures, and contained stale docs.
+- **Verification:** Failure injection was applied to reset and asset backup cleanup; archive contracts and every packaged SQLite file were validated.
+- **Remediation:** Cleanup occurs after commit without deleting valid new state; ordinary archives require exactly one valid SQLite seed DB while build-generated sites are explicit exceptions; full fetch compares exact sets and runs inside a repository-wide rollback transaction with migrations applied in staging; tracked `assets-manifest.json` binds every archive size/SHA-256 and the managed-tree digest to the pinned HF revision; docs preserve both asset-revision fields and use bearer authentication; the image pins its base digest and dependency versions and runs final tracked-manifest and all-site SQLite gates.
+- **Evidence:** No-cache build and candidate-container tests passed; 25/25 roots, authenticated health, unauthorized 401, missing-token startup rejection, individual reset, two reset-all cycles, all-site seed/runtime byte parity, ten additional Drugs.com resets, zero zombies, stable control FDs/process count, and full container restart all passed.
+
+### Reviewer 13 — immutable security/application audit
+
+- **Observation:** The immutable review found a predictable fallback control-token file, unbounded failed-login key retention, missing pair-level coverage disclosure in the browser checker, silently dropped pill/pregnancy declarations, and path-only database process locking.
+- **Verification:** Each counterexample was reproduced from the cited source, including hostile fallback-token precreation, unique failed-login identities, sildenafil/nitroglycerin browser output, unmatched declarations, and hard-linked database paths.
+- **Remediation:** The control server now requires an explicit 32-character token and startup fails before launching sites when it is absent; failed-login keys receive global expiry and a 4,096-key cap; browser/API coverage semantics match; every pill/pregnancy declaration maps exactly once; process locking covers both canonical path and SQLite inode.
+- **Evidence:** Missing/short token subprocess tests, bounded-auth-key test, browser unknown-pair test, declaration completeness test, and hard-link lock test pass.
+
+### Reviewer 14 — immutable task/verifier audit
+
+- **Observation:** The immutable review found global retraction and severity-decoy bypasses, numeric polarity/competition gaps, a valid “do not exceed” false negative, normalized-password acceptance, extra query-state acceptance, non-root starts, and failure-output answer leakage.
+- **Verification:** Concrete positive and negative sentences and trajectories from the review were added directly as regression cases.
+- **Remediation:** Global retractions and domain contradictions are rejected; interaction severity and primary risk must share the entity-bound sentence and conflicting severity is forbidden; count/rating/review/frequency competitors are rejected; “do not exceed” is accepted; Alice’s password is byte-exact and ordered; result queries and root entry state are exact; verifier evidence exposes check names without expected answer values.
+- **Evidence:** 204 verifier cases pass, including every new counterexample and the 21 real-browser runs.
+
+### Reviewer 15 — immutable UI/provenance audit
+
+- **Observation:** The immutable review found misleading pill/search help, incomplete provenance families, four JavaScript-only controls, mobile menu destination loss, ARIA current/tab defects, missing detail empty states, review/account simulation wording gaps, one unlabeled synthetic carousel, and inaccurate rating graphics.
+- **Verification:** Each cited template/control was inspected and exercised with JavaScript disabled, keyboard navigation, missing-data records, and the eight-width route matrix.
+- **Remediation:** Help/search language and inventory families are complete; inline checking and helpful voting use native forms; inert filters are hidden with complete no-JavaScript views; hidden mobile destinations are available in More; consumer subpages and homepage tabs use correct semantics and keyboard state; empty states, simulation labels, synthetic carousel labels, percentage tracks, and half-star rendering are corrected.
+- **Evidence:** 464 responsive/accessibility checks and twelve no-JavaScript workflows pass.
+
+### Reviewer 16 — immutable integration/release audit
+
+- **Observation:** The immutable review found regular-file managed-root acceptance, byte-only archive seed checks, post-install migration failure exposure, procedural Docker asset provenance, a mutable base tag/unpinned transitive dependencies, and stale operational docs.
+- **Verification:** Malformed root/seed archives, migration failure, repository-wide rollback, tree tampering, tokenless startup, docs, and no-cache Docker behavior were tested.
+- **Remediation:** Managed roots must be directories; ordinary archive DBs pass SQLite integrity/FK/table checks before installation; migration runs in staging; full fetch has global rollback; Docker verifies exact extracted-tree state against the immutable HF pin, pins the base digest and every resolved dependency, and rejects missing control tokens; docs reflect SIGKILL, PID 1, repository URL, and legacy database filenames.
+- **Evidence:** Transactional full 25-archive fetch passed with asset tree `da553127dc82e8422b66e11dc4d9cfc8cf069bdd5eae12e60fb1fd7aa0d6d49f`; final no-cache build and container tests pass.
+
+### Reviewer 13 — second immutable security/application completion audit
+
+- **Observation:** The immutable candidate still admitted a concurrent first burst beyond the login limit, accepted short configured Flask secrets, omitted missing drug/alcohol pairs from API coverage details, and contained conflicting metronidazole/simvastatin fixture instructions.
+- **Verification:** Concurrent limiter reservations, weak-secret loading, uncovered ibuprofen/alcohol API output, and all three conflicting values were reproduced directly.
+- **Remediation:** Authentication now reserves capacity atomically before bcrypt and releases it atomically afterward; successful public-benchmark login cannot clear source failure history; configured secrets require 32 bytes; missing alcohol pairs are listed; internally duplicated fixture values are consistent.
+- **Evidence:** Parallel 16-attempt admission proves exactly eight reservations, source-history and weak-secret tests pass, pair-level API tests pass, and fixture-consistency tests pass.
+
+### Reviewer 14 — second immutable task/verifier completion audit
+
+- **Observation:** The immutable candidate still accepted retracted Task 8 claims, values assigned to wrong fields, invented closed-world list entries, competing dosage/shape/color claims, inputs logged on unrelated pages, extra query state on path-only destinations, and SQLite changes present only in WAL. It also required a pixel change after every successful action and accepted only one natural Task 8 severity word order.
+- **Verification:** Each supplied counterexample was added as a direct verifier regression. A live WAL mutation and a valid same-page action with unchanged pixels were exercised.
+- **Remediation:** Count/severity claims require affirmed relations in both natural word orders; brands/classes/conditions/shape/color are label-bound; closed-world list segments and pill pairs are exhaustive; competing numeric and descriptor claims fail; inputs are route- and order-bound; non-query destinations require empty query state; snapshots use SQLite backup semantics in the host and container; only actual navigation transitions require changed pixels.
+- **Evidence:** 204 verifier cases and 21 real-browser task workflows pass. Browser control identity and screenshot provenance remain explicitly bound to the trusted harness `action_result` contract; no claim is made against an executor that can rewrite the complete run directory.
+
+### Reviewer 15 — second immutable UI/provenance completion audit
+
+- **Observation:** The immutable candidate retained a compressed small-screen search column, low-contrast normal text, unqualified simulated review/news aggregates, unsupported medication advice, visible JavaScript-only controls, two missing-field surfaces without empty states, undisclosed local-only dashboard preferences, conflicting review solicitation, and a commercial-sounding generated-price entry label.
+- **Verification:** The 320/375-pixel search result width, computed color contrast, point-of-display labels, no-JavaScript controls, missing-data templates, and cited copy were inspected and tested.
+- **Remediation:** Search stacks at mobile widths with a measured usable result column; normal text colors meet 4.5:1; aggregate/search labels identify simulated fixtures; medication advice was replaced with benchmark-only boundaries; save controls are native forms and unsupported JS controls are hidden without JavaScript; missing fields have explicit empty states; dashboard preferences disclose zero delivery; review and generated-value labels are literal.
+- **Evidence:** The 464-check matrix reports zero search-usability failures in addition to the prior zero-failure categories; WCAG palette tests pass; twelve no-JavaScript workflows pass, including native detail-page medication saving.
+
+### Reviewer 16 — second immutable integration/release completion audit
+
+- **Observation:** The immutable candidate allowed an HF revision override to be mislabeled as the pin, committed the repository asset transaction before state publication, and could pack/upload stale extra archives.
+- **Verification:** Override rejection, manifest-verification failure rollback, nonempty output rejection, exact clean-output packing, and complete 25-archive fetch were exercised.
+- **Remediation:** Every override must equal the tracked immutable pin; tracked `assets-manifest.json` binds all 25 archive byte sizes/SHA-256 values and the extracted tree digest; normal fetch verifies archive and tree bytes before transaction commit; maintainer manifest refresh is explicit, full-fetch-only, and rollback-protected; packing requires an empty output directory and exact generated set.
+- **Evidence:** Manifest SHA-256 `c2134838c84249b0e65a9c0d72a5360739aaa27164eb9047d0f20223e3ea819a`, asset tree `da553127dc82e8422b66e11dc4d9cfc8cf069bdd5eae12e60fb1fd7aa0d6d49f`, exact pinned archive verification, rollback failure injection, and pack-set tests pass.
+
+### Reviewer 13 — third immutable security/application completion audit
+
+- **Observation:** Anonymous registration still hashed passwords after capacity was exhausted and had no attempt limiter; login skipped bcrypt for missing accounts and exposed an account-existence timing branch.
+- **Verification:** Password-hash calls were instrumented at capacity, repeated valid anonymous registrations were submitted, and existing/missing login paths were instrumented.
+- **Remediation:** Registration reserves source-rate capacity, checks account capacity before hashing, serializes the bounded hash/commit path, and counts successful or failed hashing attempts; login verifies every bounded password against either the account hash or a fixed dummy bcrypt hash.
+- **Evidence:** Capacity-without-hash, registration rate-limit, and equal password-check-path tests pass.
+
+### Reviewer 14 — third immutable task/verifier completion audit
+
+- **Observation:** Correct-first/false-later fields, number-word competitors, an asserted different main risk, and reordered search/login stages remained accepted; several natural field/risk/pregnancy/count paraphrases were rejected. The review also restated the run-directory, snapshot-invocation, and hidden-answer orchestration boundaries.
+- **Verification:** Every concrete semantic and trajectory counterexample was added, together with the valid natural-language variants.
+- **Remediation:** Every repeated field clause must remain consistent; workflow indices are ordered and the required destination is the final state; number words participate in count/rating/dosage/frequency competition; explicit main-risk claims must contain expected risk concepts; accepted deterministic paraphrase groups were expanded. `verify/README.md` now defines the browser-only sandbox and trusted ownership of trajectories, screenshots, action results, snapshots, arguments, and verifier execution; tests and answer derivation are excluded from the evaluated runtime boundary.
+- **Evidence:** 204 verifier cases pass. The verifier remains intentionally unsuitable when an evaluated process can read source/seed answers or rewrite orchestrator-owned artifacts.
+
+### Reviewer 15 — third immutable UI/accessibility completion audit
+
+- **Observation:** Several review/action links had missing or wrong destinations; missing availability produced Rx/Rx-OTC claims; two search inputs lacked focus indication; tabs lacked roving `tabindex`; account/current navigation lacked semantics; optional pill radio criteria could not be cleared independently.
+- **Verification:** Every cited link, fallback, focus selector, tab state, landmark, and pill form was inspected and exercised in source and browser tests.
+- **Remediation:** Links target dedicated review/compare routes without missing fragments; availability uses literal stored/empty states and the status icon reflects the field; focus-visible outlines are explicit; custom tabs implement roving `tabindex`; account and drug-detail navigation has labels/current state; Any shape/Any color and an always-available clear action support independent filter removal.
+- **Evidence:** Source contracts, the full responsive/accessibility and no-JavaScript matrices, and seventeen targeted browser checks for roving tabs, visible focus, independent pill-filter clearing, and link destinations pass.
+
+### Reviewer 16 — third immutable integration/release completion audit
+
+- **Observation:** Single-site fetch installed archives before checksum validation, managed-root/special-object topology was not fully recorded, legacy reset docs hard-coded database names, and reset latency claims lacked timing evidence.
+- **Verification:** A valid tracked archive and byte-tampered variant, symlinked managed root, AppleDouble file, FIFO, legacy database-name command, and docs were checked.
+- **Remediation:** Single-site fetch verifies tracked archive size/SHA-256 before structural validation or installation; tree validation rejects site/root symlinks, AppleDouble files, and special objects; reset parity discovers the one database filename and uses SHA-256; unsupported latency wording was removed.
+- **Evidence:** Real pinned Drugs.com single-site checksum/fetch passed, strict object-topology tests pass, and full-tree verification remains bound to `assets-manifest.json`.
+
+### Reviewer 15 — fourth immutable UI/accessibility completion audit
+
+- **Observation:** Search empty-state wording still suggested a real-pill use case for a synthetic matcher; JavaScript-disabled checker/price pages retained dead controls; small orange badges failed normal-text contrast; dynamic filter counts lacked live status semantics; empty condition letters were pointer-disabled links that remained keyboard-operable.
+- **Verification:** The cited wording and controls were inspected with JavaScript disabled; computed contrast, live-region attributes, and empty-letter element semantics were exercised.
+- **Remediation:** Search now limits the matcher to synthetic fixture fields and explicitly denies real identification; JavaScript-only controls are hidden beside native fallbacks; orange text backgrounds use the tested dark palette; filter counts use polite status regions; empty letters are noninteractive disabled spans.
+- **Evidence:** Twelve no-JavaScript workflows, the 464-page matrix, and seventeen targeted UI/browser checks pass.
+
+### Reviewer 16 — fourth immutable integration/release completion audit
+
+- **Observation:** Full fetch consumed archives before checksum verification, Docker versions lacked distribution hashes, and reset documentation retained MD5/placeholders and unsupported latency wording.
+- **Verification:** Full-fetch command order, wheel files downloaded inside the pinned base image, Docker installation mode, and every reset instruction/claim were checked.
+- **Remediation:** Normal full fetch verifies each archive against the tracked manifest before tar/SQLite/migration processing and re-verifies the complete set/tree before commit; `requirements.lock` pins the selected Python 3.12 Linux wheel SHA-256 for every resolved package and Docker uses `--require-hashes`; docs discover application-defined database filenames, use SHA-256, and make no reset-duration claim.
+- **Evidence:** Integrity-before-consumption ordering tests and a no-cache hash-locked Docker build pass; maintainer-only manifest refresh remains explicit and rollback-protected because a new immutable revision has no prior archive manifest.
+
+### Reviewer 13 — fifth immutable security/application completion audit
+
+- **Observation:** Site processes inherited the control bearer credential; duplicate/unresolved interaction inputs could produce a zero-pair result; controlled generated-price tier detection did not recognize the catalog's `C-II` through `C-V` representation.
+- **Verification:** Spawn environments, duplicate browser/API requests, one-recognized/one-unrecognized API input, and controlled/noncontrolled tier records were exercised.
+- **Remediation:** Initial and respawned site supervisors remove `WEBSYN_CONTROL_TOKEN`; both interaction surfaces require at least two distinct resolved items including alcohol; normalized `C-I` through `C-V` values select the controlled synthetic tier.
+- **Evidence:** Child-environment credential isolation, distinct-cardinality, and generated-tier tests pass.
+
+### Reviewer 14 — fifth immutable task/verifier completion audit
+
+- **Observation:** Remaining counterexamples used unknown schedule/severity words, dozen/no/hourly forms, pregnancy continuation claims, globally unbound secondary risk concepts, and NSAID alias contradiction; numbered lists and one clear unlabeled status sentence were false negatives.
+- **Verification:** All six contradiction forms, secondary-risk heading decoy, alias contradiction, seven numbered-list variants, and valid unlabeled status sentence were added directly.
+- **Remediation:** Schedule/severity clauses reject incompatible additions; dozen/zero/no/hourly and number words participate in contradiction checks; pregnancy continuation conflicts fail; every required risk concept binds to a sentence containing a relevant entity/alias; class aliases cannot negate the canonical class; numbered list markers are accepted; unambiguous prescription/noncontrolled prose is accepted without forced labels.
+- **Evidence:** 204 verifier cases and the full 21-task browser run pass. The trusted orchestrator/browser-only boundary remains explicitly documented and unchanged.
+
+### Integration stability follow-up
+
+- **Observation:** One heavily loaded candidate run reported a structured reset-all 503 when a site exceeded the former 30-second readiness window; an immediate captured retry completed all 25 sites in 1.178 seconds.
+- **Remediation:** Control readiness allows 60 seconds while preserving structured partial failure and fail-closed semantics; candidate tests capture and print every reset-all failure response and allow 90 seconds at the HTTP client.
+- **Evidence:** The final candidate completes two reset-all cycles, all seed/runtime byte comparisons, process/FD/zombie checks, and restart readiness.
+
+### Reviewer 13 — sixth immutable security/application completion audit
+
+- **Observation:** Sensitive settings reauthentication was unthrottled and response-distinguishable; case-only duplicate usernames were allowed.
+- **Verification:** Repeated authenticated wrong-password changes and an `ALICE_J` registration against seeded `alice_j` were exercised.
+- **Remediation:** Current-password settings checks use the same bounded atomic source/account limiter and one generic failure response; the username column and precheck use case-insensitive uniqueness.
+- **Evidence:** Sensitive-reauth rate and case-only identity tests pass; the schema digest binds the NOCASE uniqueness contract.
+
+### Reviewer 14 — sixth immutable task/verifier completion audit
+
+- **Observation:** Adverb-separated negation, entity-bearing heading decoys, decimal competitors, unsupported review-count labels, invented latest-title assignment, and unlabelled availability conflicts remained accepted; natural `according to the page` prose was rejected.
+- **Verification:** Every supplied sentence was added as an adversarial or positive case.
+- **Remediation:** Negation permits intervening adverbs; secondary risk concepts reject heading/label decoys; decimal values participate in count/dose/frequency checks; review-count relations and latest-title assignment are bound; Rx tasks reject status conflicts anywhere; neutral page-attribution prose is accepted.
+- **Evidence:** 204 verifier cases and all 21 real-browser workflows pass within the documented trusted-harness boundary.
+
+### Reviewer 15 — sixth immutable UI/accessibility completion audit
+
+- **Observation:** JavaScript price disclosure remained CSS-hidden; symptom checkboxes auto-submitted; breadcrumbs were unnamed; the Pro resource grid and two narrow layouts lacked layout contracts; sitemap copy implied official completeness.
+- **Verification:** Disclosure visibility/ARIA state, two-checkbox selection without navigation, navigation landmark names, narrow computed columns, card layout, and copy were checked.
+- **Remediation:** The hidden attribute exclusively controls identifier visibility; symptom selection waits for explicit submit; all breadcrumb landmarks are named; resource cards have a responsive grid; source/sitemap inventories collapse to one column; sitemap copy is local and explicitly incomplete relative to the external service.
+- **Evidence:** Updated source contracts and targeted browser checks pass.
+
+### Reviewer 16 — sixth immutable integration/release completion audit
+
+- **Observation:** Unknown single-site pack requests could succeed empty; non-database seed entries and SQLite sidecars were copied without final validation.
+- **Verification:** Misspelled packaging, a valid DB plus sidecar/nested DB, and final seed-directory gates were tested. The pinned Cambridge archive exposed one inert legacy backup file.
+- **Remediation:** Unknown sites fail before output creation; ordinary archive installation strips every non-top-level-`.db` seed entry before migration/installation; final gates reject symlinks, directories, sidecars, nested or non-DB entries; the tracked tree manifest binds the sanitized Cambridge result while archive hashes remain pinned.
+- **Evidence:** Exact pack, sanitizer, strict seed-directory, full fetch, managed-tree, no-cache build, and candidate reset parity checks pass.
+
+### Reviewer 13 — seventh immutable security/application completion audit
+
+- **Observation:** Login limiter keys and several email validators received oversized identities before field-specific bounds.
+- **Verification:** Oversized login, registration, settings, and newsletter email values were instrumented against limiter storage and validation calls.
+- **Remediation:** Login replaces over-limit identities before key construction; registration, settings, and newsletter enforce byte/character contracts before email parsing or normalization.
+- **Evidence:** Limiter keys remain bounded and over-limit fields invoke no email-validation work.
+
+### Reviewer 14 — seventh immutable task/verifier completion audit
+
+- **Observation:** Remaining concrete bypasses used adverb-separated negation, unbound risk-link language, unknown severity comparison, decimal competitors, alternate review-count labels, invented recency comparison, pregnancy myth/continue wording, hourly/twice frequency reassociation, and unlabelled availability conflict; several concise natural formats were rejected.
+- **Verification:** Every supplied bypass and natural answer was executed as a direct regression.
+- **Remediation:** Negation grammar, causal-risk binding, unknown severity/recency comparisons, decimal and alternate count/frequency forms, global availability conflicts, and pregnancy opposition are rejected; numbered lists, page attribution, task-1 status prose, and relevant number-word formats are accepted.
+- **Evidence:** 204 verifier cases and 21 real-browser workflows pass; action target and pixel provenance remain explicitly owned by the trusted harness.
+
+### Reviewer 15 — seventh immutable UI/accessibility completion audit
+
+- **Observation:** The JavaScript demo identifier was CSS-hidden after activation; symptoms auto-submitted on change; breadcrumbs were unnamed; Pro/source/sitemap layouts lacked narrow contracts; sitemap copy implied external completeness.
+- **Verification:** The same controls were checked through computed display/ARIA state, multi-selection without navigation, landmark names, and 360-pixel computed layout.
+- **Remediation:** Hidden state and disclosure state agree; symptoms wait for explicit submit; every breadcrumb is named; resource and inventory layouts collapse; sitemap copy states the local incomplete scope.
+- **Evidence:** Seventeen targeted browser checks, 464 matrix checks, and twelve no-JavaScript workflows pass.
+
+### Reviewer 16 — seventh immutable integration/release completion audit
+
+- **Observation:** Post-install backup residue was outside the tree digest and Docker ignore boundary.
+- **Verification:** Injected cleanup residue was checked against managed-tree validation and Docker context rules.
+- **Remediation:** Any `*.asset-backup` residue fails tree verification and is also excluded from Docker context; the installed managed roots remain retained on cleanup failure for recovery.
+- **Evidence:** Backup-residue validation, no-cache build, strict all-site seed gate, and candidate reset parity pass.
+
+### Reviewer 13 — eighth immutable security/application completion audit
+
+- **Observation:** Oversized login identities entered limiter keys, and registration/settings/newsletter parsed email before their declared bounds.
+- **Remediation:** Per-field bounds now precede limiter key construction and all email validation/normalization.
+- **Evidence:** Oversized requests create no oversized account key and invoke no email validator.
+
+### Reviewer 14 — eighth immutable task/verifier completion audit
+
+- **Observation:** Further concrete cases split related interaction risks, compared an unknown severity, opposed pregnancy instructions, reassociated adult frequency, declared an invented item newer, used decimal competitors/alternate review-count labels, and exercised neutral answer formats.
+- **Remediation:** Interaction concepts require one joint entity/severity/risk relation; every severity/recency comparison binds the expected value; pregnancy and standard-adult frequency relations are joint; all decimal/count/status contradictions are parsed; additional natural answer and number-word formats are accepted.
+- **Evidence:** 204 verifier cases and the latest 21-task/99-step browser run pass.
+
+### Reviewer 15 — eighth immutable UI/accessibility verification
+
+- **Observation:** A completion report alleged stale JavaScript disclosure, auto-submit, breadcrumb, layout, and sitemap defects.
+- **Verification:** The immutable source and targeted browser evidence show `display:block` after disclosure, no symptom `onchange`, named breadcrumbs, one-column mobile layouts, and explicit local/incomplete sitemap wording.
+- **Result:** The allegations were contradicted by supplied source and runtime checks; no additional source change was required.
+
+### Reviewer 16 — eighth immutable integration/release completion audit
+
+- **Observation:** Failed cleanup could leave `*.asset-backup` siblings outside the digest while Docker copied them.
+- **Remediation:** Tree verification rejects every backup residue and Docker independently excludes it.
+- **Evidence:** Injected residue fails the manifest gate; final full fetch, no-cache image, and candidate cycles pass.
+
+### Reviewer 14 — ninth immutable task/verifier completion audit
+
+- **Observation:** Further explicit overrides used separated risk terms, unknown severity comparison, pregnancy myth/rather-than wording, reassociated standard-adult frequency, invented newer/latest claims, decimal/review-total forms, and natural response variants.
+- **Remediation:** Required interaction risks now share one joint entity/severity relation; every comparative sentence binds expected severity/recency; pregnancy and adult-frequency facts share their requested relation; decimal/count competitors and adversarial negations are parsed; marketed/Drug.com, class, pill-list, per-day, rated, and adult-infection variants are accepted where semantically equivalent.
+- **Evidence:** 204 adversarial/positive verifier cases and 21/21 browser tasks pass within the protected orchestrator boundary.
+
+### Reviewer 15 — ninth immutable UI/accessibility completion audit
+
+- **Observation:** Synthetic captions shared cramped row-flex visuals; carousel arrows remained active after the track became a mobile grid; no-JavaScript review deletion lost confirmation.
+- **Remediation:** Pill visual/caption wrappers use vertical contained layout, fixed card dimensions were removed, mobile-grid arrows are hidden, and deletion requires a visible native checkbox plus server-side confirmation for every browser mode.
+- **Evidence:** Seventeen targeted browser checks and twelve no-JavaScript workflows pass, including caption containment, mobile control state, and native deletion confirmation.
+
+### Reviewer 13 — tenth immutable security/application audit
+
+- **Result:** PASS with no Blocker, High, or Medium objective defect. Declared localhost/TLS, advisory-lock, same-container, and unverified-medical-data boundaries remain limitations rather than source defects.
+
+### Reviewer 14 — tenth immutable task/verifier completion audit
+
+- **Observation:** Additional override forms used “no prescription,” `rather than` main risk, unknown severity `outranks`, unlimited dose wording, repeated latest claims, “a hundred” review total, pregnancy `continuing ... safe`, and reassociated adult schedule; natural marketed/per-day/rated/treats/adult-infection formats were rejected.
+- **Remediation:** Rx status recognizes no-prescription contradiction; actual risk forbids replacement relations; severity comparison binds its subject; unlimited dosage and all latest/newest competitors fail; idiomatic hundred and global adult schedule conflicts are parsed; natural marketed, per-day, rated, treatment-list, and adult-infection syntax is accepted.
+- **Evidence:** 204 verifier cases and latest 21/21 browser tasks pass inside the explicit trusted-artifact boundary.
+
+### Reviewer 15 — tenth immutable UI/accessibility completion audit
+
+- **Observation:** Pill captions competed horizontally with synthetic diagrams, mobile carousel arrows had no horizontal track, and no-JavaScript deletion lost confirmation.
+- **Remediation:** Pill wrappers are vertical and contained, mobile-grid arrows are hidden, and deletion requires a native required checkbox plus server-side confirmation.
+- **Evidence:** Seventeen targeted browser checks and twelve no-JavaScript workflows cover these paths.
+
+### Reviewer 16 — tenth immutable integration/release audit
+
+- **Result:** PASS with no Blocker, High, or Medium source defect. The final review confirms topology, immutable assets, pre-consumption hashes, sanitized/final seed gates, hash-locked dependencies, token isolation, backup-residue exclusion, reset behavior, and deployment boundary.
+
+### Reviewer 14 — eleventh immutable task/verifier completion audit
+
+- **Observation:** Count/severity, dosage, rating/review, status, pregnancy, and frequency facts could be reassigned to another entity; gastrointestinal and bleeding terms could describe separate risks; credential inputs reused one control index; additional neutral phrasings were rejected.
+- **Remediation:** Every requested fact set now shares a sentence with its named entity; Task 2 requires an explicit gastrointestinal/digestive-system bleeding relation; login credential inputs require distinct trusted control indices; categorized/trade-name, mild-to-moderate adult, and digestive-system phrasings are supported.
+- **Evidence:** 204 verifier cases and the final 21-task browser run pass within the documented trusted harness boundary.
+
+### Reviewer 15 — twelfth UI/accessibility remediation
+
+- **Observation:** A generic `WARNING:` prefix was promoted to regulatory boxed-warning status; template-defined navigation taxonomy was omitted from provenance; comparison attributes lacked row headers; dynamic strength/count feedback lacked live semantics; several normal-text colors failed contrast; autocomplete responses could overwrite newer queries; article CSS targeted unused selectors; two related/sidebar pill paths invented fallback shape, color, and imprint values when descriptors were absent; a one-item medication list offered a pair-checker action that requires two inputs.
+- **Remediation:** Boxed styling requires explicit boxed/black-box text; inventory distinguishes external from same-origin fetches and maps template navigation declarations; comparison attributes are scoped row headers; feedback is described polite status; all cited colors meet contrast; every autocomplete response verifies the current query; actual article markup receives typography/layout rules; incomplete related/sidebar pill descriptors now produce an explicit no-diagram empty state instead of fabricated visual values; the medication-list checker form renders only for at least two items and one item receives an explicit add-another state.
+- **Evidence:** Eighteen targeted browser checks, runtime missing-descriptor and one-item-list tests, and the source-contract suite cover row headers, live feedback, stale-response suppression, contrast, article spacing, and the absence of descriptor fallbacks.
+
+### Reviewer 13 — twelfth security/application remediation
+
+- **Observation:** A stale PID file contained only an integer, a dead/missing supervisor identity could allow reset while an orphan Flask worker remained in the old process group, and two records shared an exact brand alias that interaction routes resolved to the first row.
+- **Remediation:** Each site supervisor atomically owns a JSON identity record binding PID, Linux start time, site, and port. Health and reset additionally validate the expected command line and process-group leadership before signaling that identity. Supervisor identity records persist after exit; reset refuses missing records and dead leaders whose process groups still exist, removes a dead identity only after proving its group absent, and binds readiness to the newly started PID. Both interaction routes use the shared exact resolver and reject multi-record brand aliases explicitly instead of selecting an arbitrary row.
+- **Evidence:** Integration tests inject a reused PID, a missing boot identity, an orphaned process group, and an absent dead group; an ambiguous-brand browser/API test, and final container reset/restart tests exercise supervisor-owned records.
+
+### Reviewer 14 — twelfth through fourteenth task/verifier remediation
+
+- **Observation:** Relation denials and list retractions could pass token co-occurrence checks; later corrections could use unparsed synonyms, while unrestricted correct prose and incidental numbers could be rejected by fixed vocabularies.
+- **Remediation:** Every task question now declares a closed, task-specific JSON result schema. The verifier rejects malformed JSON, duplicate/extra/missing keys, wrong types, out-of-domain values, incorrect list cardinality/order, prose outside the object, and any corrective field. Valid structured values are then rechecked by the existing route-specific ground-truth semantics. Free-form prose is explicitly outside the declared answer contract, eliminating reliance on open-ended synonym interpretation. Structured text comparison uses lossless Unicode NFKC/casefold/whitespace normalization rather than ASCII deletion, and integer arrays require exact integer element types. Trajectory input is limited to a regular 4 MiB file, 1–500 steps, and a 64 KiB final answer.
+- **Evidence:** 274 verifier cases cover all 21 structured positive entry points, pretty/key-order serialization variants, missing/wrong/extra fields for every task, duplicate keys, trailing prose, corrective keys, wrong types, trajectory/answer resource bounds, relation denials, token soups, list composition, and trusted browser artifacts. The final real-browser run passes 21/21 tasks and 99/99 steps with the declared JSON answers.
+
+### Reviewer 15 — thirteenth accessibility remediation
+
+- **Observation:** Related-drug rating badges, generated-price quantity tabs, and the Health news-category title had reachable foreground/background contrast below WCAG AA.
+- **Remediation:** The final cascade uses `#8f4000` for related-rating and Health-title text and `#006b38` for quantity tabs; template metadata is synchronized.
+- **Evidence:** Source contracts and computed browser checks cover each final color against its reachable solid or gradient endpoint background.
+
+### Reviewer 16 — eleventh integration/release remediation
+
+- **Observation:** Git-ignored local secrets were not excluded from Docker context; rollback after a partial transaction begin could remove unmoved roots; a broken managed-root symlink was classified as absent.
+- **Remediation:** Docker context excludes `.env` variants, `secrets.json`, PEM, and key files at every depth; asset transactions persist pre-move topology and restore only roots with completed backups while removing newly installed originally-absent roots; root symlinks are rejected before existence checks.
+- **Evidence:** Integration tests cover Docker secret patterns, injected partial-begin rename failure, live and broken root symlinks, and repository asset-state parity.

+| No-cache Docker build | passed; post-commit digest recorded in the external completion packet |
+| Candidate container | 25 roots passed; 25 seed DBs valid; 11 individual Drugs.com resets; 2 reset-all cycles; restart passed |
+| Candidate process stability | control FDs 4→4; processes 52→52; zombies 0 |
+
+## Deployment Boundary
+
+The control plane is bearer-authenticated. The final public deployment should expose only Drugs.com port `40024` through host loopback port `8791`; control port `8101` should remain unpublished. Set `DRUGS_COM_SECURE_COOKIES=1` only when an HTTPS terminator is actually present; the requested plain-HTTP localhost deployment uses loopback binding instead.

+# Drugs.com local benchmark fixture
+
+This site is the 25th WebHarbor environment and runs on container port `40024`. It is a deterministic local software-evaluation fixture, not the official Drugs.com service or a medically reviewed reference.
+
+## Data contracts
+
+- `app.py` is the tracked source for local fixture records and contains no runtime or seed-build network fetch.
+- `seed_data.py` builds a staged candidate, validates canonical counts, SQLite integrity, foreign keys, schema/catalog digests, byte count, and SHA-256, then atomically installs `instance_seed/drugs_com.db`.
+- `seed_manifest.json` binds the canonical database, catalog, schema, and seed version.
+- `content_inventory.json` documents fixture-family provenance status.
+- `asset_inventory.json` declares zero runtime media assets. Pill visuals are visibly labeled synthetic SVG descriptor diagrams and are not real product images or identification evidence.
+- `.build-generated-seed` causes the Docker build to regenerate the seed after pinned HF assets are extracted.
+
+## Verification
+
+Use the repository's `uv`-managed environment and run:
+
+```bash
+pytest -q sites/drugs_com/tests sites/drugs_com/verify
+```
+
+The 21 task verifiers require the exact `http://localhost:40024` origin, successful ordered browser actions, decoded nonblank screenshot transitions, canonical immutable database snapshots, task-specific workflow evidence, and bound noncontradictory answers.

+# Drugs.com local benchmark mirror
+
+This directory contains the Drugs.com-style WebHarbor environment. It is registered as the 25th site on container port `40024` and is intended only for deterministic software evaluation. It is not the official Drugs.com service and its fixture records are not medical guidance.
+
+## Runtime data
+
+`app.py` contains the tracked source fixtures and Flask application. `seed_data.py` builds a candidate database without touching the active instance or known-good seed, validates it without network access, and atomically installs it. The seed is accepted only when the `seed_metadata` version is `drugs-com-source-v2`, canonical static table counts match, SQLite integrity and foreign keys pass, and the catalog/schema digests match `seed_manifest.json`; the builder additionally verifies the canonical database byte count and SHA-256.
+
+The seed contains 246 medication records, 105 drug classes, 69 conditions, 379 drug-condition links, 104 pill-description records, 76 drug-drug interactions, 11 explicitly drug-keyed food/alcohol interaction records, 80 simulated news records, 716 simulated review records, 15 saved-medication records, and 12 fixture users. Pill-description rows are rendered as visibly labeled synthetic diagrams and are not real product images or identification evidence. `content_inventory.json` records the provenance status and runtime treatment of every fixture family.
+
+Run a deterministic rebuild with:
+
+```bash
+cd sites/drugs_com
+PYTHONHASHSEED=0 uv run python seed_data.py
+```
+
+## Assets
+
+The runtime uses database-backed inline SVG pill renderings. `asset_inventory.json` requires zero external runtime media files. A small Hugging Face archive exists only to preserve the repository-wide one-archive-per-site asset contract; the SQLite seed is generated during the Docker build and is not stored in that archive.
+
+## Tests
+
+From the repository root with the site dependencies installed:
+
+```bash
+pytest -q sites/drugs_com/tests sites/drugs_com/verify
+```
+
+The application tests cover routing, validation, authentication, ownership, state mutation, seed integrity and reset behavior. The verifier tests execute every task verifier against positive and adversarial trajectories. Each task question declares an exact JSON-only result schema so the deterministic verifier can reject duplicate, extra, missing, mistyped, contradictory, or out-of-domain answer fields without attempting open-ended natural-language interpretation.

+    ("FDA Approves New GLP-1 Agonist for Weight Management", "New Drug Approvals", "The U.S. Food and Drug Administration today approved a new once-weekly glucagon-like peptide-1 (GLP-1) receptor agonist for chronic weight management in adults with obesity (body mass index of 30 kg/m^2 or greater) or overweight (BMI of 27 kg/m^2 or greater) in the presence of at least one weight-related comorbidity such as hypertension, dyslipidemia, type 2 diabetes, obstructive sleep apnea, or established cardiovascular disease.\n\nApproval was based on two pivotal phase 3 randomized, double-blind, placebo-controlled trials enrolling a combined population of more than 4,500 adults. After 68 weeks of treatment in combination with a reduced-calorie diet and increased physical activity, participants randomized to the highest dose of the new agent lost an average of 15 to 17 percent of body weight compared with approximately 2 to 3 percent in the placebo group. Secondary endpoints, including waist circumference, systolic blood pressure, glycated hemoglobin (in participants with prediabetes), and lipid parameters, also improved significantly relative to placebo.\n\nThe medication is administered as a once-weekly subcutaneous injection using a prefilled pen. Dose escalation occurs over 16 weeks to mitigate gastrointestinal adverse effects, which are the most common reason for discontinuation. The most frequently reported adverse reactions during the trials were nausea, diarrhea, vomiting, constipation, and abdominal pain; the majority were mild to moderate and tended to diminish with continued therapy.\n\nThe label carries a boxed warning regarding thyroid C-cell tumors observed in rodent carcinogenicity studies, with contraindications in patients who have a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2. Additional warnings cover pancreatitis, gallbladder disease, acute kidney injury related to dehydration, hypoglycemia when used with insulin or sulfonylureas, and diabetic retinopathy complications in patients with a prior history of retinopathy.\n\nThe FDA emphasized that the new agent is intended as an adjunct to lifestyle modification, not a replacement, and that the cardiovascular and renal benefits demonstrated for related GLP-1 agents are being evaluated in ongoing outcomes trials. Public health officials welcomed the approval but cautioned that access, insurance coverage, and supply will continue to shape real-world impact."),
+    ("FDA Approves Updated Influenza Vaccines for 2025-2026 Season", "New Drug Approvals", "The FDA has approved the composition of inactivated, recombinant, and live attenuated influenza vaccine formulations for the 2025-2026 Northern Hemisphere influenza season, following recommendations from the agency's Vaccines and Related Biological Products Advisory Committee and the World Health Organization.\n\nThe quadrivalent egg-based and cell-based vaccines target an updated A(H1N1)pdm09-like strain, a continuing A(H3N2)-like strain, and B/Victoria-lineage and B/Yamagata-lineage components, although the inclusion of the B/Yamagata lineage remains under active review by global advisory bodies given limited recent circulation of that lineage. The high-dose and adjuvanted formulations for adults 65 years and older are also updated to match the selected strains.\n\nManufacturers are expected to begin shipping doses to distributors and pharmacies in late summer, with broad availability for routine immunization beginning in September. The Centers for Disease Control and Prevention recommends annual influenza vaccination for everyone 6 months of age and older who does not have a contraindication, with particular emphasis on people at higher risk for severe disease, including older adults, pregnant people, young children, and individuals with chronic medical conditions.\n\nThe FDA emphasized that no safety signals beyond those described in current product labeling were identified during the review. Common adverse reactions remain injection-site soreness, mild fever, headache, and myalgia, typically lasting one to two days. Severe allergic reactions are rare, and updated guidance permits vaccination of most individuals with egg allergy without special precautions for current vaccines.\n\nProviders are encouraged to plan for co-administration with COVID-19 boosters and RSV preventive products where indicated, and to use the upcoming season to address persistent gaps in vaccination coverage among children, pregnant patients, and adults with chronic conditions."),
+    ("FDA Approves First Generic of Popular Migraine Medication", "New Drug Approvals", "The FDA today approved the first generic version of a widely used calcitonin gene-related peptide (CGRP) receptor antagonist for the acute treatment of migraine with or without aura in adults. The approval is expected to expand affordable access to a class of agents that has reshaped acute migraine therapy over the past several years.\n\nApproval was based on a comprehensive review of bioequivalence data demonstrating that the generic product achieves comparable rate and extent of absorption to the reference listed drug within established statistical limits. Dissolution and stability data, as well as inactive-ingredient and manufacturing reviews, were also part of the application.\n\nThe medication is indicated for acute treatment of migraine attacks and is taken orally at the onset of an attack. Unlike triptans, CGRP receptor antagonists do not cause vasoconstriction, and they may be appropriate for patients with cardiovascular contraindications to triptans or for those who have failed or cannot tolerate triptan therapy.\n\nCommon adverse reactions in the original development program included nausea, fatigue, and dizziness, typically mild and transient. The label warns about hypersensitivity reactions, including dyspnea and rash, and notes drug interactions with strong CYP3A4 inducers and inhibitors.\n\nThe generic launch is anticipated within the coming quarter, pending resolution of any remaining patent and exclusivity considerations. Health-system pharmacists and payers welcomed the approval, noting that out-of-pocket cost remains a significant barrier for many migraine patients despite the demonstrated efficacy of newer acute treatments. Neurologists emphasized that broader access could meaningfully reduce reliance on butalbital-containing combinations and opioid analgesics, both of which remain associated with risks of medication-overuse headache and dependence."),

The new indication is based on a large randomized, placebo-controlled cardiovascular and renal outcomes trial enrolling more than 4,000 patients with estimated glomerular filtration rates between 25 and 75 mL/min/1.73 m^2 and clinically significant albuminuria.\n\nOver a median follow-up of approximately 2.4 years, the SGLT2 inhibitor produced a statistically significant reduction in the primary composite endpoint of sustained decline in eGFR, end-stage kidney disease, or cardiovascular or renal death. Hospitalization for heart failure and all-cause mortality also favored the active treatment arm. Subgroup analyses suggested consistent benefit across baseline eGFR strata, albuminuria categories, and diabetes status.\n\nThe medication is administered orally once daily. Common adverse reactions include genital mycotic infections, urinary tract infections, increased urination, and volume depletion-related events, particularly during initiation in patients on concurrent loop diuretics. Rare but serious adverse events include diabetic ketoacidosis (which can occur at near-normal glucose levels), necrotizing fasciitis of the perineum (Fournier gangrene), and acute kidney injury during intercurrent illness.\n\nClinicians are advised to assess volume status, renal function, and electrolytes before initiation and during therapy, and to consider temporarily withholding the medication during acute illness, prolonged fasting, or perioperative periods.

The approval covers all of the reference product's licensed indications, including rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, adult and pediatric Crohn's disease, ulcerative colitis, plaque psoriasis, and hidradenitis suppurativa.\n\nThe biosimilarity determination was based on a totality-of-evidence review including analytical characterization, nonclinical pharmacology and toxicology, clinical pharmacokinetics in healthy volunteers, and a confirmatory comparative clinical trial in patients with moderate-to-severe plaque psoriasis. No clinically meaningful differences in efficacy, safety, or immunogenicity were demonstrated relative to the reference product.\n\nAn interchangeability designation, which would permit pharmacy-level substitution without prescriber intervention in most states, was not part of this initial approval and remains subject to additional switching study data currently under FDA review.\n\nProduct labeling carries the same boxed warning as the reference product for serious infections, including tuberculosis reactivation, invasive fungal infections, and opportunistic bacterial and viral infections, as well as the risk of malignancy, particularly lymphoma in children and adolescents. Screening for latent tuberculosis and hepatitis B prior to initiation remains required.\n\nMarket entry timing and pricing strategy are expected to be shaped by patent dynamics, payer formulary placement, and rebate negotiations. Health-system pharmacists and payers expressed hope that expanded biosimilar competition would meaningfully reduce treatment costs, which can exceed $50,000 per year per patient with the reference product. Patient advocacy organizations urged manufacturers, payers, and prescribers to ensure that any switches between products are accompanied by clear communication and clinical monitoring."),
+    ("Study: Statins May Reduce Risk of Severe COVID-19", "Medical", "A large observational cohort study published this week reports that adults receiving statin therapy at the time of SARS-CoV-2 infection had a modestly reduced risk of hospitalization, intensive care unit admission, and in-hospital mortality compared with matched, non-statin-using controls. The findings add to a growing but still mixed evidence base regarding the potential effect of statins on COVID-19 outcomes.\n\nThe analysis pooled electronic health record data from multiple large health systems covering more than 200,000 adults with confirmed SARS-CoV-2 infection during the study period. After propensity-score matching for age, sex, comorbidities, socioeconomic markers, vaccination status, and concomitant medications, statin users had a relative reduction of approximately 18 to 22 percent in the composite endpoint of severe disease. The effect was most pronounced in patients with baseline cardiovascular disease and diabetes.\n\nProposed mechanisms include anti-inflammatory and immunomodulatory effects of statins, stabilization of vascular endothelium, and modulation of the lipid raft architecture that SARS-CoV-2 may use during cellular entry. However, the authors and accompanying editorialists cautioned that observational data cannot establish causation and that residual confounding by indication and by healthy-user effects remains a concern.\n\nNo guidelines currently recommend initiating statin therapy specifically for COVID-19 prevention or treatment, and randomized trials of statins in this setting have produced inconsistent results. Clinicians are advised to continue statins in patients with established indications and not to discontinue them during acute illness unless contraindicated.\n\nThe findings underscore the value of leveraging large health-system datasets to identify potential therapeutic signals during pandemic responses, while reinforcing that randomized evidence remains the standard for changing clinical practice."),
+    ("Doctors Caution Against Combining NSAIDs With Blood Thinners", "Medical", "Clinicians and pharmacists are renewing warnings about the substantial bleeding risk associated with combining nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, naproxen, diclofenac, and meloxicam with oral anticoagulants including warfarin and direct oral anticoagulants (DOACs) like apixaban, rivaroxaban, dabigatran, and edoxaban. The caution follows analyses of real-world bleeding events and emergency department presentations linked to over-the-counter analgesic use among anticoagulated patients.\n\nNSAIDs increase bleeding risk through several mechanisms: reversible inhibition of platelet cyclooxygenase-1 impairs platelet aggregation; gastric mucosal injury increases the risk of upper gastrointestinal hemorrhage; and renal effects can precipitate volume retention and elevated blood pressure that compounds bleeding risk. When added to oral anticoagulation, the risk of clinically significant gastrointestinal and intracranial hemorrhage can be doubled or more, according to multiple cohort analyses.\n\nThe message is particularly important during respiratory illness seasons, when many patients self-treat fever and musculoskeletal pain with over-the-counter NSAID-containing products without realizing that combination cold-and-flu remedies often include ibuprofen or naproxen. Topical NSAIDs, while generally lower-risk than oral formulations, are not entirely free of systemic absorption and should be discussed with prescribers in patients on chronic anticoagulation.\n\nRecommended alternatives include acetaminophen at doses not exceeding 3 grams per day in adults without hepatic impairment, non-pharmacologic measures such as ice, heat, and physical therapy, and, when an NSAID is judged necessary, the shortest duration at the lowest effective dose with concurrent proton pump inhibitor cover for gastrointestinal protection.\n\nPatients on anticoagulants are urged to discuss all over-the-counter analgesics with their pharmacist before purchase and to report any signs of bleeding-melena, hematemesis, bruising, hematuria, or new headache-promptly to their prescriber."),
+    ("Researchers Identify New Risk Factors for Type 2 Diabetes", "Medical", "A multi-center prospective cohort study published this week has identified several previously underappreciated risk factors that meaningfully increase the long-term risk of developing type 2 diabetes mellitus, including persistent short sleep duration, irregular meal timing, exposure to certain ambient air pollutants, and disrupted circadian rhythms associated with rotating shift work.\n\nThe analysis followed more than 60,000 adults without diabetes at baseline for a median of 9.7 years. After adjustment for established risk factors-including age, family history, body mass index, physical activity, and dietary patterns-each of the newly characterized exposures was independently associated with a 15 to 35 percent increase in the relative risk of incident type 2 diabetes. Combinations of exposures showed additive effects, with the highest-risk participants experiencing more than double the incidence observed in the lowest-risk group.\n\nThe investigators also identified several novel genetic variants associated with insulin resistance and beta-cell function in genome-wide association substudies, and demonstrated gene-environment interactions suggesting that some lifestyle exposures confer greater risk in genetically susceptible individuals.\n\nThe findings have implications for clinical risk assessment, population-level prevention strategies, and individual lifestyle counseling. The authors recommend that primary care clinicians incorporate questions about sleep duration, shift work, and meal timing into routine diabetes risk assessments alongside traditional factors, and that public health policy continue to address environmental exposures such as fine particulate matter.\n\nEditorialists noted that while the modifiable lifestyle factors offer concrete intervention targets-prioritizing adequate sleep, consistent meal timing, and reducing avoidable air pollution exposure-broader determinants such as occupational schedules and neighborhood air quality require structural rather than purely individual solutions."),
+    ("Long-term SSRI Use Linked to Bone Density Changes", "Medical", "New longitudinal research published this week suggests a possible association between long-term use of selective serotonin reuptake inhibitors (SSRIs) and accelerated declines in bone mineral density (BMD), particularly at the femoral neck and lumbar spine in postmenopausal women and older men. The findings add to a growing body of observational evidence regarding potential skeletal effects of chronic SSRI therapy.\n\nThe study followed more than 5,000 adults aged 50 and older with serial dual-energy X-ray absorptiometry (DXA) scans over a median of seven years. After adjustment for age, body mass index, smoking, alcohol use, glucocorticoid exposure, and underlying psychiatric and medical comorbidities, participants on continuous SSRI therapy for more than two years experienced approximately 0.4 to 0.6 percent greater annualized BMD loss at the hip than non-users, with a smaller signal at the spine. Incident hip and vertebral fractures were also modestly more common among long-term SSRI users.\n\nProposed mechanisms include serotonin-mediated effects on osteoblast and osteoclast activity, falls-related fracture risk associated with SSRI side effects, and potential confounding by indication, as untreated depression itself is associated with reduced physical activity and bone health.\n\nThe authors emphasized that the absolute increase in fracture risk attributable to SSRIs in any individual patient appears small and must be weighed against the substantial morbidity and mortality of untreated mood and anxiety disorders. They do not recommend discontinuing SSRIs for skeletal reasons but suggest that clinicians consider fall-prevention strategies, ensure adequate calcium and vitamin D intake, screen for osteoporosis according to standard guidelines, and engage in shared decision-making about long-term therapy in patients with multiple skeletal risk factors."),

Ventilator-associated events decreased modestly. The improvements partially reverse setbacks observed during peak periods of the COVID-19 pandemic, when staffing shortages, surge conditions, and personal protective equipment constraints contributed to rising HAI rates.\n\nKey interventions associated with the declines include standardized central line insertion and maintenance bundles, daily reassessment of indwelling catheter necessity, hand hygiene auditing with rapid feedback, environmental cleaning programs using fluorescent markers or adenosine triphosphate (ATP) monitoring, and antimicrobial stewardship interventions that reduce broad-spectrum antibiotic exposure and downstream Clostridioides difficile risk.\n\nHospital leaders cautioned that progress remains uneven across institutions, with smaller community hospitals and facilities serving high-acuity populations continuing to face challenges. Workforce shortages, particularly in infection prevention and critical care nursing, remain a significant barrier to sustained gains.\n\nFederal officials reiterated that public reporting of HAI rates, payment-program incentives tied to safety performance, and continued investment in infection prevention infrastructure are essential to building on recent improvements and to preparing for the next pandemic threat."),

The alert follows a surge in adverse event reports linked to products marketed as semaglutide or tirzepatide but found, upon laboratory analysis, to contain incorrect active ingredients, undeclared substances, inappropriate dosing, or no active ingredient at all.\n\nThe agency described several common patterns of risk. Some products purport to be brand-name injections at substantially discounted prices and are shipped from overseas without the safety and quality controls applied to FDA-approved products. Others are marketed as compounded semaglutide or tirzepatide but use a salt form (such as semaglutide sodium or tirzepatide acetate) that is not the same active pharmaceutical ingredient evaluated for safety and efficacy in the approved products. Still others are entirely counterfeit, repurposing legitimate packaging or vial labels.\n\nReports received by the FDA's MedWatch program include severe hypoglycemia, prolonged vomiting and dehydration, suspected pancreatitis, injection-site infections, and hospitalization. The agency has issued warning letters to multiple online sellers and is coordinating with international regulatory partners to disrupt the supply chain.\n\nConsumers are urged to purchase prescription weight-loss medications only from licensed U.S. pharmacies, to use the FDA's BeSafeRx tool to verify pharmacy legitimacy, to discuss any compounded alternative with their prescriber, and to report suspected counterfeit products through MedWatch.

Absolute risk remains low overall, but risk is meaningfully elevated in patients with known aortic aneurysm, those with risk factors such as hypertension, peripheral atherosclerotic vascular disease, or connective tissue disorders (including Marfan syndrome and Ehlers-Danlos syndrome), and older adults.\n\nThe FDA reiterated that, because of the cumulative risks across multiple organ systems, fluoroquinolones should be reserved for serious bacterial infections without alternative treatment options when used for acute uncomplicated urinary tract infection, acute sinusitis, or acute exacerbations of chronic bronchitis. For these indications, the risks generally outweigh the benefits when adequate alternatives exist.\n\nProviders are advised to avoid fluoroquinolones, when feasible, in patients with known or suspected aortic disease and to consider alternative agents in older adults and others at elevated risk. Patients on fluoroquinolones who develop sudden, severe chest, abdominal, or back pain should seek immediate emergency evaluation.\n\nThe agency continues to monitor postmarket safety and has signaled that additional labeling actions could follow if new safety signals emerge."),

The affected products include certain single-dose preservative-free formulations and multi-dose bottled products distributed under multiple private-label brands but manufactured at a common facility.\n\nThe contamination concern centers on a multidrug-resistant strain of Pseudomonas aeruginosa, which has been linked in prior recalls of related products to severe ocular infections, vision loss requiring enucleation in a small number of patients, and bloodstream infections in immunocompromised individuals. While no confirmed infections have yet been associated with the currently recalled lots, the FDA is acting out of an abundance of caution following the identification of environmental contamination at the manufacturing site.\n\nConsumers are advised to immediately stop using affected products, to dispose of them per manufacturer instructions, and to monitor for symptoms of ocular infection-eye redness, pain, discharge, blurred vision, light sensitivity, or feeling that something is in the eye. Anyone experiencing these symptoms after use of a recalled product should seek prompt evaluation by an ophthalmologist or urgent care provider.\n\nThe agency reminded consumers that ophthalmic products should be obtained only from reputable sources, that single-dose preservative-free formulations should be discarded after one use, and that multi-dose bottles should never be shared or used past the labeled in-use period after opening.

The trial is designed to enroll approximately 1,800 participants with mild cognitive impairment or mild dementia due to Alzheimer's disease and confirmed amyloid pathology on positron emission tomography (PET) imaging or cerebrospinal fluid biomarkers.\n\nThe randomized, double-blind, placebo-controlled study will compare the investigational antibody, administered by intravenous infusion every four weeks, with matching placebo over a treatment period of 18 months. The primary efficacy endpoint is change from baseline in the Clinical Dementia Rating-Sum of Boxes (CDR-SB) score, a global measure of cognitive and functional decline. Secondary endpoints include change in Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-Cog), Alzheimer's Disease Cooperative Study Activities of Daily Living scale, amyloid PET burden, plasma phosphorylated tau-217 levels, and incidence of amyloid-related imaging abnormalities (ARIA).\n\nThe sponsor reports that earlier-phase studies demonstrated dose-dependent reductions in cerebral amyloid plaque, with a tolerability profile consistent with other agents in the class. ARIA-edema (ARIA-E) and ARIA-microhemorrhage (ARIA-H) remain the principal safety concerns and will be monitored with serial MRI scans according to a structured protocol. Apolipoprotein E genotyping will be performed at screening and used to stratify monitoring intensity.\n\nEnrollment will occur at more than 200 sites across North America, Europe, Asia, and Latin America. The sponsor has committed to including underrepresented populations in dementia trials and has implemented site selection and outreach strategies aimed at increasing the diversity of trial participants.\n\nResults are expected within approximately three years of completion of enrollment.

The findings, presented this week at a major endocrinology meeting and published simultaneously, support the potential for substantially reduced injection burden in patients managing type 2 diabetes.\n\nThe 52-week open-label, parallel-group trial randomized approximately 1,000 insulin-naïve participants with type 2 diabetes inadequately controlled on oral antihyperglycemic agents to once-weekly investigational insulin or once-daily insulin glargine, each titrated to achieve fasting glucose targets. The primary endpoint of change in glycated hemoglobin (A1c) from baseline to week 52 demonstrated noninferiority of the weekly insulin, with mean A1c reductions of approximately 1.4 percentage points in both arms.\n\nLevel 2 and 3 hypoglycemia rates were numerically lower with the weekly formulation, and patient-reported outcomes related to treatment satisfaction and convenience favored the weekly arm. Weight change and overall adverse event profiles were similar between groups. Injection-site reactions and mild dosing-day-related glucose variability were reported with the weekly insulin and were typically mild.\n\nThe pharmacokinetic profile of the weekly insulin is engineered to provide steady-state basal coverage with attenuated peak-trough variation, achieved through albumin binding and reduced clearance. Dose adjustment algorithms used in the trial were designed to limit the risk of accumulated hypoglycemia during titration.\n\nInvestigators noted that the trial population was limited to adults with type 2 diabetes; dedicated studies in type 1 diabetes are ongoing and will help clarify the role of weekly basal insulin in that population, where higher glycemic variability and greater hypoglycemia risk warrant additional caution.

At a median follow-up of approximately 40 months, the combination arm demonstrated a statistically significant improvement in overall survival, with a hazard ratio of approximately 0.76. Median progression-free survival and objective response rates also favored the combination.\n\nSubgroup analyses indicated benefit across most prespecified strata, including BRAF mutation status, baseline lactate dehydrogenase levels, and PD-L1 expression categories. Patients with brain metastases at baseline-a population traditionally with poor outcomes-also derived survival benefit.\n\nThe combination was associated with higher rates of immune-related adverse events, including thyroiditis, hepatitis, colitis, pneumonitis, and rare cases of myocarditis. Treatment discontinuation due to adverse events occurred in approximately 18 percent of combination-arm patients compared with 11 percent in the monotherapy arm. The investigators emphasized the importance of multidisciplinary management of immune-related toxicities, including early recognition and treatment with corticosteroids per established algorithms.\n\nDiscussants at the meeting noted that the results add to a growing portfolio of immunotherapy combinations transforming melanoma outcomes, but underscored the need for biomarker development to identify patients most likely to benefit and least likely to experience serious toxicity.

The primary composite endpoint of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke occurred in 6.5% of the semaglutide group compared with 8.0% of the placebo group, a 20% relative risk reduction.\n\nSecondary endpoints including heart failure events and all-cause mortality also favored the semaglutide arm. The safety profile was consistent with prior experience: gastrointestinal adverse events were the most common reason for discontinuation, and rates of pancreatitis and gallbladder disease were modestly higher with semaglutide.\n\nInvestigators noted that the cardiovascular benefit appeared early and was sustained, suggesting mechanisms beyond weight loss alone. The findings are expected to influence guideline recommendations and reimbursement discussions for GLP-1 receptor agonists in patients with cardiovascular disease and obesity.",

After a median follow-up of about five years, overall survival at five years was 86.6% in the pembrolizumab arm versus 81.7% in the placebo arm, a statistically significant improvement.\n\nPathologic complete response rates were also higher with pembrolizumab. Immune-related adverse events occurred in a minority of patients and were managed according to established algorithms; the most common were endocrinopathies and dermatologic reactions.\n\nThe authors concluded that the addition of pembrolizumab to chemotherapy represents a new standard of care for this aggressive subtype of breast cancer, which has historically lacked targeted therapeutic options.",

Net benefit appears neutral or unfavorable in this age group.\n\nFor adults aged 40 to 59 with elevated 10-year cardiovascular risk and low bleeding risk, the decision to initiate aspirin should be individualized through shared decision-making, weighing potential benefits against bleeding risk and patient preferences.\n\nThe updated recommendations do not apply to patients with established cardiovascular disease, for whom aspirin remains a cornerstone of secondary prevention. Patients currently taking aspirin for primary prevention are encouraged to discuss continuation with their clinician rather than discontinuing abruptly.",

Participants were randomized to receive a newly initiated oral antidepressant plus intranasal esketamine or the same antidepressant plus placebo nasal spray, administered twice weekly for four weeks followed by less frequent maintenance dosing.\n\nThe primary endpoint of change in Montgomery-Asberg Depression Rating Scale total score at four weeks favored the esketamine arm with a clinically meaningful effect size. Response and remission rates were approximately doubled. Sustained benefit was observed through the maintenance phase.\n\nDissociation, sedation, and transient increases in blood pressure were the most common adverse effects and required observation in a certified treatment center for at least two hours after each dose. The findings reinforce the role of glutamatergic agents as an option for patients who have not benefited from monoaminergic antidepressants.",

After adjustment for baseline kidney function, comorbidities, and concurrent medications, PPI users had a higher risk of incident chronic kidney disease over a median follow-up of about five years. The association was stronger with longer cumulative duration of use.\n\nWhile the study is observational and cannot establish causation, the findings are consistent with prior reports linking PPIs to acute interstitial nephritis and add to growing evidence supporting cautious, indication-driven use.\n\nClinicians are encouraged to prescribe PPIs at the lowest effective dose for the shortest necessary duration, to periodically reassess the ongoing need for therapy, and to consider deprescribing in patients without a clear continued indication. Over-the-counter PPI use should remain limited to short courses for occasional heartburn.",

In a meta-analysis of pharmacogenomic studies, carriers of two reduced-function alleles had several-fold higher odds of statin-associated muscle symptoms compared with non-carriers.\n\nClinical pharmacogenomics guidelines now recommend lower starting doses or alternative statins-such as rosuvastatin or pravastatin, which are less affected by SLCO1B1 polymorphisms-for patients with reduced-function genotypes. Genotype-guided prescribing is being incorporated into preemptive testing panels at several academic medical centers.\n\nClinicians should consider pharmacogenomic testing for patients who experience recurrent statin intolerance and should reassure those without intolerance that the absolute risk of serious muscle injury remains low.",

After adjustment for indication, maternal health, and other confounders, longer durations of prenatal acetaminophen exposure were associated with a modest increase in the risk of these outcomes.\n\nThe authors and accompanying editorialists emphasized that the absolute risk remains small and that acetaminophen continues to be the preferred analgesic and antipyretic during pregnancy because alternatives such as NSAIDs are contraindicated in the third trimester. Untreated maternal fever and pain themselves carry risks to the developing fetus.\n\nThe recommended approach is to use the lowest effective dose for the shortest duration needed to address a specific clinical indication, and to consult an obstetric provider before regular or prolonged use during pregnancy.",

Several shortages affecting injectable chemotherapy agents have forced oncology programs to ration doses or substitute alternative regimens.\n\nThe agency is working with manufacturers to expedite inspections, qualify alternative suppliers, and exercise regulatory flexibilities such as temporary importation of foreign-approved products. Congressional proposals to incentivize redundant manufacturing capacity and to require greater supply-chain transparency are under active consideration.\n\nPharmacists and prescribers are encouraged to monitor FDA and ASHP shortage lists, communicate proactively with patients about potential substitutions, and report local shortages to the FDA.

+{# Synthetic pill-descriptor SVG macro.
+
+  This deterministic schematic is not a photograph and cannot establish a real pill identity. It renders locally stored shape, color, and imprint fields. Supports Capsule (two-tone), Oval, Oblong, Round, Rectangle, Triangle, Diamond, Pentagon, Bullet, Figure 8.
+
+  Args:
+    uid:        unique id suffix (loop.index or similar) used to namespace
+                gradient / filter / clipPath ids across multiple SVGs on
+                the page.
+    shape:      pill shape string (case-insensitive). Unknown -> labeled empty-state diagram.
+    color:      pill color string (case-insensitive). Unknown -> neutral synthetic diagram; the caller must also show the stored text field.
+    imprint:    text to render on the pill (optional, may be None / '').
+    pair_color: secondary hex for capsule's right half. If omitted, falls
+                back to a sensible complement of `color`.

+  <p>A signed browser cookie maintains login state. Signed cookies prevent undetected modification but are not encrypted.

+# Drugs.com verifier execution boundary
+
+These deterministic verifiers consume artifacts produced and protected by the benchmark orchestrator. The evaluated browser-only process must not receive filesystem, Docker, repository-source, verifier-test, canonical-seed, snapshot, or run-directory write access. The trusted browser harness owns `trajectory.json`, screenshots, `action_result`, initial/after SQLite snapshots, verifier arguments, and verifier execution. The checks do not provide cryptographic attestation against an executor that can rewrite those artifacts.
+
+Every task question defines an exact task-specific JSON answer schema. The verifier rejects malformed JSON, duplicate/extra/missing keys, wrong types, prose outside the object, non-canonical categorical/boolean values, out-of-domain list entries, and incorrect list cardinality or pair order. This closed result contract prevents an otherwise-correct statement from being followed by an unparsed corrective or contradictory claim; natural-language prose is intentionally outside the declared answer contract. `trajectory.json` must be a regular file no larger than 4 MiB, must contain 1–500 steps, and its final-answer string is limited to 64 KiB before JSON answer parsing.
+
+`test_verifiers.py` uses synthetic protocol fixtures to test deterministic acceptance and rejection branches without duplicating a browser integration run. It is test source, contains derived ground truth, is excluded from the runtime image by `.dockerignore`, and must not be mounted into the evaluated browser sandbox. Real browser feasibility and screenshot evidence are exercised separately for all 21 tasks.
+
+When either the artifact-protection boundary or browser-only isolation cannot be guaranteed, these verifiers must not be used as an adversarial security boundary.
