From 1f0da682111bd5dcecf5de1219d4ef080c865ef7 Mon Sep 17 00:00:00 2001 From: Claude Assistant Date: Tue, 21 Apr 2026 22:19:21 -0700 Subject: [PATCH 01/36] ci: sentry sourcemaps upload + android internal track workflow MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Wires eas-hooks/post-build-sentry.sh (written 2026-04-21) into GitHub Actions because EAS Build does not support eas.json-level afterBuild or onSuccess fields (confirmed against Expo custom-builds + npm-hooks docs). npm lifecycle hooks (eas-build-on-success) run in the EAS sandbox where SENTRY_AUTH_TOKEN is not available, so sourcemap upload must run in CI instead. ci.yml changes: - Add push on tags v* and workflow_dispatch (ios_build_id input) as triggers in addition to existing main/PR triggers. - New job upload-ios-sourcemaps: resolves latest finished production iOS build via eas build:list, downloads the artifact, extracts the ipa + dSYM + source maps into build-artifacts/, invokes the hook script, then uploads any .dSYM bundles for native symbolication. New .github/workflows/android-internal.yml: - workflow_dispatch (profile/track/skip_submit inputs) and tag push v*-android triggers. - Installs EAS CLI, materializes ANDROID_GOOGLE_SERVICE_ACCOUNT_KEY into google-service-account.json (path that eas.json expects). - eas build --platform android --profile --wait, then eas submit against the matching submit profile (internal -> preview, beta -> beta, production -> production). - On production builds, invokes post-build-sentry.sh for Android sourcemap upload. Cleans up service account key on exit. All workflow_dispatch inputs are channeled through env: blocks before shell use to prevent command injection. eas.json is intentionally not modified — no supported hook field exists; hook wiring lives in the workflows instead.

A logMethod hook also pipes the top-level msg through redactPHI. - query_analytics_log insert site now pipes original_query, normalized_query, llm_prompt, llm_response through sanitizeForQueryLog before Supabase insert. In-memory buffer stays raw for dev inspection.

Risks + +- **Build 41 regression surface**: `scoring-agency-rules.ts` holds three clinically-critical rules that landed 2026-04-21 (iOS Build 40/41): `BARE_PROTO_RE` (scoring-agency-rules.ts:101), bridge-chunk penalty branch (scoring-agency-rules.ts:253-255), and `isPediatricWeightDrugQuery` -> Ref-1309 boost (scoring-agency-rules.ts:261-269). Extraction must preserve exact regex semantics, exact call order inside `applyAgencyRerankRules`, and exact multiplier references; no inlining of the multipliers, no regex simplification, no reordering relative to peds-refusal/EDAP/destination blocks. +- **Duplicate regex divergence**: `DOSAGE_PATTERN` (patterns.ts:10) and `DOSING_INFO_PATTERN` (patterns.ts:59) are identical today; collapsing to one requires confirming basic-rerank (`scoring.ts:113`) and advanced-rerank (`scoring.ts:262`) still fire for the same queries. +- **Intent categories pinned**: `contraindication_check` / `medication_dosing` / `pediatric_specific` are hard-coded in the Haiku classifier prompt (intent-classifier.ts:44-54). Any safety-module rename must not change the wire values the LLM returns. +- **OpenFDA contract stability**: `OpenFDADrugInfo` shape (openfda.ts:20-34) is consumed by routers outside these 7 files; `fetchDrugSafetyProfile` must wrap, not replace, and keep `source: "openfda"` tag intact. +- **Audience classifier ordering**: `ADULT_AUDIENCE_RE` must be evaluated against `-P` protocol suffix rule block (scoring-agency-rules.ts:325-338) before `pedsPediatricBoost` fires. Moving the regex without moving the ordering breaks adult/peds routing. +- **LA-DROP diabetic penalty coupling**: `DIABETIC_QUERY_RE` (scoring-agency-rules.ts:90) participates in both the blood-product penalty branch (163-176) and `QUERY_TITLE_BOOSTS` `blood sugar` key (80-84). Regex must stay single-source. +- **Quality gate untouched**: `validateResultQuality` uses raw `similarity` (quality.ts:41), not reranked score. Safety extraction must not change this invariant or the minimum-threshold semantics. +- **Quick-reference-data.ts size**: file is ~441 lines and near the 500-LOC rule. Merging safety pulls from it is read-only; avoid editing the file or it risks crossing the limit. + +## 6. Rollout Order + +**Phase 1 — extract read-only primitives (smallest blast radius).** Create `safety/patterns.ts` re-exporting from `rag/patterns.ts` under `SAFETY_PATTERNS` alias. Create `safety/audience.ts` with `classifyAudience` and `isWeightBasedPedsDrugQuery` as pure wrappers importing from `scoring-agency-rules.ts`. No call-site changes. Snapshot-run the gold Q&A set (per CLAUDE.md Phase 2c) — expect 0 diffs. + +**Phase 2 — swap consumers.** In `rag/scoring.ts` (medication_dosing, contraindication_check, pediatric_specific branches), swap regex constants for `SAFETY_PATTERNS.*` and call `scoreDoseContent` / `scoreContraindicationContent` / `scorePediatricContent`. Then in `rag/scoring-agency-rules.ts`, replace inline `PEDS_AUDIENCE_FULL_RE.test(queryPhrase) && DRUG_QUERY_RE.test(queryPhrase) && PEDIATRIC_WEIGHT_RE.test(queryPhrase)` with `isWeightBasedPedsDrugQuery(queryPhrase)` — keep the Ref-1309 multiplier and rule location unchanged. Re-run gold Q&A; require byte-identical ranking. + +**Phase 3 — add orchestration (`profile.ts`).** Wrap `fetchOpenFDADrug` with `fetchDrugSafetyProfile` + `mergeSafetyProfiles` that can overlay `QuickReferenceCard` contras/peds notes. No existing caller changes; new routers consume the wrapper.

It is one of a paramedic's most consequential calls — legally, clinically, and for the family on scene. + +The policy exists because not every cardiac arrest is a resuscitation candidate. Some patients arrive with signs incompatible with life, and transporting those patients ties up resources, exposes the crew to risk, and delays closure for the family. + +## H2: Who Can Apply Ref 814 + +**[MD REVIEW — confirm scope statements are accurate.]** + +Both EMTs and paramedics may apply Ref 814 when the criteria are unambiguously met. The policy is structured so that line-of-sight signs of irreversible death (for example, decomposition) do not require a paramedic on scene. However, paramedics carry the cardiac monitor required for the asystole-confirmation pathway that triggers withholding resuscitation in the absence of obvious signs. + +Practical translation: +- **EMT-only crew** — can pronounce when one of the absolute obvious-signs criteria is met (rigor, lividity, decomposition, injury clearly incompatible with life). +- **Paramedic crew** — can pronounce when obvious signs are met OR when the patient is in asystole confirmed by monitor in two leads with the applicable protocol followed. + +## H2: The Criteria at a Glance + +**[MD REVIEW — the list below is a reference-level summary, not a verbatim copy of the policy. Do not quote-for-quote without written permission. Confirm the summary matches current Ref 814 language.]** + +Absolute signs (any one supports determination without resuscitation): +- Decomposition. +- Rigor mortis (generalized, not focal). +- Dependent lividity. +- Decapitation, incineration, or injury clearly incompatible with life. + +Asystole pathway (paramedic with monitor, in absence of absolute signs): +- Asystole confirmed in two leads. +- No indications to override (hypothermia, drowning with down-time uncertainty, toxicologic cause in young patient — see current policy for full exclusion list). +- Appropriate duration of resuscitation attempted and documented if applicable. + +## H2: Common Gotchas + +### Gotcha 1 — Rigor mimics +Jaw stiffness from trismus or post-mortem generalized rigor can be confused. Generalized rigor spreading beyond the jaw is the documented sign; focal rigor is not enough. + +### Gotcha 2 — Lividity position dependence +Lividity only appears in dependent areas. A supine patient may show posterior lividity; a prone patient shows it anteriorly. Patients moved after death may have non-dependent lividity, which changes interpretation. Document scene position. + +### Gotcha 3 — Hypothermia exclusion +"Nobody is dead until they are warm and dead" is the classic teaching. Hypothermic cardiac arrest is an explicit exclusion in most determination-of-death policies including Ref 814 [MD REVIEW]. If core temperature is low or unknown-but-plausibly-low (ice rescue, exposure), transport and resuscitate. + +### Gotcha 4 — Pediatric patients +Policy language around pediatrics is generally stricter. Confirm current Ref 814 for any pediatric-specific criteria. When in doubt, transport. + +### Gotcha 5 — Legal paperwork +Ref 814 is not just clinical — it triggers paperwork. Coroner notification, PCR documentation of criteria, and law-enforcement coordination are required. A call that ends at Ref 814 on scene still generates a detailed report. + +## H2: How Protocol Guide Helps + +**[Non-commercial framing — keep the clinical tone primary.]** + +Protocol Guide surfaces Ref 814 with voice search or plain text. Ask "Ref 814 criteria" and the app returns the agency-authored summary, with a link to the current policy PDF. Pediatric asides, exclusion list, and documentation requirements are all one scroll away. + +The app is jurisdiction-scoped, so paramedics in LA County see LA County Ref 814, paramedics in a neighboring county see their own policy. No cross-jurisdiction confusion. + +## H2: Field Checklist (not a substitute for the policy) + +When approaching a potential determination-of-death call: + +1. Secure the scene and protect the crew. +2. Confirm the patient's identity and position. +3. Assess for absolute signs of death. Document what you see in concrete terms. +4. If no absolute signs, run the applicable resuscitation protocol. +5. If asystole persists and the policy criteria are met, apply Ref 814 per current guidance. +6. Notify base/coroner per LA County procedure. +7. Support the family. Request law enforcement if needed. +8.

Always defer to your county policy. + +## H2: How to Tell Which License Level Can Give Which Drug + +**[MD REVIEW — confirm the decision rules below reflect current policy.]** + +A practical decision rule, in order: + +1. **Is the medication in the patient's own possession and is the provider assisting?** If yes, even an EMT may assist with it (epi pen, inhaler, oral nitro with specific criteria). +2. **Is the medication in the EMT baseline Title 22 list?** Oxygen, oral glucose, aspirin, naloxone IN, epinephrine auto-injector for severe allergic reaction. Yes, EMT may administer. +3. **Does the LEMSA have an EMT optional scope expansion for this drug?** Check your county policy. Examples vary — some counties approve EMT albuterol, some don't. +4. **Is the medication in the AEMT list under Title 22 § 100080?** If yes and your county has approved AEMTs, AEMT may administer per county policy. +5. **Otherwise, paramedic scope.** + +The asymmetry matters on scene. An EMT who pushes a drug outside scope is outside their license, regardless of good intent. Document the scope basis for every med given. + +## H2: Worked Example — Chest Pain Call + +An adult patient with chest pain, BP 140/90, HR 90, awake and oriented. + +- EMT crew — oxygen if hypoxic, assist with patient's own nitro (county protocol permitting), aspirin per protocol, rapid transport, ALS intercept. +- AEMT crew — the above plus IV access and saline per protocol. +- Paramedic crew — the above plus 12-lead interpretation, STEMI activation, IV analgesics per protocol, cardiac monitor, transport to STEMI-capable facility if indicated. + +Every step above must align with the applicable LEMSA policy for that call type. + +## H2: Common Gotchas + +### Gotcha 1 — "Standing order" vs "base hospital contact" +Some medications and procedures are standing-order for paramedics in one county and require base-hospital contact in another. Title 22 does not dictate this — your LEMSA does. + +### Gotcha 2 — Cross-border EMS +A paramedic licensed by LA County EMS Agency has accreditation in LA County, not automatic accreditation statewide. Mutual-aid and accreditation reciprocity are county decisions. Don't assume scope carries across the county line. + +### Gotcha 3 — AEMT rollout varies +As of the most recent Title 22 amendment cycle, AEMT is authorized statewide, but not every LEMSA has deployed AEMT staffing. If you transfer counties, confirm the LEMSA's AEMT status. [MD REVIEW — confirm current statewide status.] + +### Gotcha 4 — "Optional scope" does not mean optional for the provider +Once a LEMSA has approved an expanded scope (for example, EMT naloxone IN), providers in that county must carry it per policy.

Re-read the disclaimer — pediatric dosing is the single most error-prone category in prehospital care, and language must not read as prescriptive. + +--- + +## H1: Pediatric Weight-Based Dosing in the Field + +## H2: Why Pediatric Dosing Is a Different Animal + +An adult patient gets 1 mg of epinephrine for cardiac arrest. A pediatric patient gets 0.01 mg/kg. A miscalculation on a 20 kg child can mean a tenfold dose error. Stress, low light, family screaming, and a crew working in the back of a moving ambulance all magnify that risk. + +That is why pediatric dosing in EMS has moved away from on-the-fly arithmetic toward pre-calculated, visually-anchored reference systems — the Broselow-Luten tape and its color-code dosing partners. + +## H2: The Broselow-Luten Tape at a Glance + +The Broselow-Luten emergency tape is a length-based resuscitation tape introduced in the 1980s and refined across multiple editions. The principle: length correlates with median weight within a narrow age range. Measure the child from crown to heel and read off the color zone. + +Each color zone carries: +- An estimated weight range. +- Pre-calculated drug doses for critical medications. +- Equipment sizes (ETT, BVM, suction catheter, NG tube). +- Defibrillation energies in joules. + +The tape does not replace clinical judgment. A chronically underweight child or an obese child can read one zone lower or higher than their chronologic age would suggest — but the tape is still measuring length, and length-based dosing is validated as safer than weight-guessed dosing under stress. + +## H2: Color Code Drug Doses and LA County Ref 1309 + +**[MD REVIEW — confirm Ref 1309 is the current LA County policy number for Color Code Drug Doses, or adjust.]** + +Several counties — LA County included — publish their own color-coded pediatric drug dose charts aligned to the Broselow colors. LA County's chart lives under Reference 1309, Color Code Drug Doses. + +Why publish a county version on top of a commercial tape? + +1. **Agency-specific formulary.** County formulary may not match the tape's pre-printed doses drug-for-drug. +2. **Route differences.** IN naloxone, IO access, and IM epinephrine doses vary by agency guidance. +3. **Scope-of-practice alignment.** Some drugs on commercial tapes are not in LA County paramedic scope; the county chart suppresses those. +4. **Version control.** Commercial tapes are updated on vendor schedules. County policy updates whenever medical direction changes. A county-published chart is the source of truth for the county. + +In the field, the practical workflow is: +1. Measure the child. +2. Read the color. +3. Confirm against the county Color Code chart (printed, tablet, or in Protocol Guide). +4. Draw up the dose. +5. Have a second provider verify before administration when feasible. + +## H2: Common Pitfalls + +### Pitfall 1 — Using the tape upside down +The tape has a head-end marker. Measuring from foot to head gives the wrong color band. This is the most common rookie error. + +### Pitfall 2 — Guessing weight when the tape is available +"The kid looks about 20 kilos" sounds reasonable and is wrong roughly a third of the time under stress. The tape is present for a reason; use it. + +### Pitfall 3 — Volume errors on epinephrine +Epinephrine for pediatric arrest is 0.01 mg/kg of 0.1 mg/mL (cardiac strength). Pulling the wrong concentration vial — 1 mg/mL instead of 0.1 mg/mL — causes a tenfold overdose. Clear labeling, two-person verification, and following the color chart mitigate this. + +### Pitfall 4 — Maximum dose caps +Some pediatric doses cap at the adult dose. For example, adenosine dosing caps at 6 mg first dose, 12 mg repeat, even for larger adolescents. A strict mg/kg read without checking the cap produces an adult-exceeding dose. + +### Pitfall 5 — Defibrillation energy confusion +Pediatric defib starts at 2 J/kg, then 4 J/kg, then 4-10 J/kg per guidance. Some crews default to adult-style 200 J or biphasic-equivalent, which is outside the pediatric range. The color chart shows the joules by zone. + +### Pitfall 6 — Missing the "teal" or "grey" zones +Some tapes include a grey (newborn) zone and a teal zone for the largest pediatric range. Crews sometimes skip straight to "white" (adult) for a near-adult adolescent. Weight-based for pediatrics runs to ~40 kg before switching to adult dosing per most policies — check your county. + +### Pitfall 7 — Not re-verifying across shift change +If a pediatric patient is held for monitoring and crews swap, the incoming crew should verify the tape zone and weight independently. Hand-off errors compound. + +### Pitfall 8 — Oral vs parenteral same-name confusion +Diazepam PO, IV, and PR are not the same dose. Midazolam IM, IV, IN are different. The tape simplifies but doesn't remove this risk — always confirm the route and the concentration drawn. + +## H2: Worked Example — Pediatric Seizure + +A 4-year-old with active generalized seizure for 8 minutes. Tape measures yellow zone. + +**[MD REVIEW — confirm dose values align with current county pediatric status-epilepticus guidance. Values below are illustrative and must be verified.]** + +1. Confirm color zone — yellow. +2. Protect airway, apply oxygen, suction as needed. +3. Check the Color Code chart for first-line benzodiazepine: + - Midazolam IN — value per chart. + - Midazolam IM — value per chart. + - Midazolam IV/IO — value per chart. +4. Administer per route available. Re-dose per policy if seizure persists. +5. Re-check glucose. Treat hypoglycemia per color chart. +6. Transport with cardiac monitor, document times. +7. Notify receiving facility of meds given, routes, and times. + +The article deliberately does not print drug dose values. These must come from the live LA County Color Code chart, not a blog post. Protocol Guide surfaces them when the app is opened to the applicable zone. + +## H2: How Protocol Guide Helps + +Protocol Guide integrates Color Code lookups with voice or text search. Ask "pediatric seizure yellow zone" and the app returns the agency's chart row — with source citation to Ref 1309 — in under 2 seconds. Always verify with the printed tape on your rig and your medical director's guidance. + +On scope: weight-based pediatric dosing is paramedic-level in California. EMTs assist with oxygen, positioning, and transport. AEMT programs in approving counties expand this slightly. See the companion article "EMT vs Paramedic in California" for the scope table. + +## H2: Field Checklist + +Before every pediatric drug push: +1. Confirm tape zone by measurement. +2. Confirm the drug name, concentration, and route in the chart. +3. Verify the calculated dose does not exceed the maximum cap. +4. Draw up and label the syringe. +5. Second-provider verification if staffing allows. +6. Administer. +7. Document the zone, the dose, the time, and the two providers involved. + +## H2: Source and Further Reading + +- Luten R. et al., Broselow-Luten pediatric emergency system — primary references. +- Los Angeles County EMS Agency — Reference 1309 Color Code Drug Doses (current revision).

Implementation ticketed separately. + +--- + +## 1. Funnel Definition + +Seven stages, mapped to App Store and TestFlight handoffs. + +| Stage | Event | Property / metadata | Success signal | +|-------|-------|---------------------|----------------| +| 1. Landing view | `page_view` on `/` | referrer, UTM, device class | Viewable impression (>1s in viewport). | +| 2. Scroll 50% | `scroll_depth` at 50% | section last in view | Not bounce. Medium intent. | +| 3. Video play | `video_play` on hero product demo | duration watched, completion % | Engaged. High intent signal. | +| 4. CTA click | `cta_click` on "Get Protocol Guide" | button location (hero / mid / footer) | Declared intent. | +| 5. App Store click | `outbound_click` to `apps.apple.com/...` | button, section, device | Hand-off to Apple. | +| 6. TestFlight install | Derived from App Store Connect Analytics "first-time install" | device, region, source | Committed user. | +| 7. Subscribe | Stripe checkout `checkout.session.completed` (webhook) | plan, trial, region | Paying user. | + +**Attribution approach:** +- Stages 1-5 owned by analytics tool (see Section 2). +- Stage 6 owned by App Store Connect Analytics + App Store Attribution API. Correlate via UTM propagated to App Store (custom product pages + `pt=` / `ct=` query params). +- Stage 7 owned by Stripe + our backend. Cross-reference by user email OR StoreKit transaction ID once RevenueCat (v2) ships. + +**Handoff gap:** stages 5-6 are probabilistic, not deterministic.

Conservative given some users bounce after expansion. | +| App Store click → Install | **3%** | Target. Apple industry avg 25-30% but from App Store browsing, not referral; referral is lower. | +| Install → Subscribe (within 14 days) | **5%** | Target conversion of trial-to-paid. | +| Blended Landing → Subscribe | ~0.4% | Approx product of the above. | + +**Re-baseline cadence:** after 2 weeks of steady traffic, reset targets based on observed distribution. Track week-over-week change as the real signal. + +**Red-flag triggers:** +- Video play <15%: rewrite hero headline, try new video. +- App Store click <4%: CTA copy or below-fold trust gap. +- Install <1.5%: App Store page is the bottleneck — re-test screenshots (see `aso-screenshot-spec.md`). +- Subscribe <2%: paywall friction — A/B price anchor or trial length. + +--- + +## 4.

Date, presenter, logo. +2. **Problem** — Binders are outdated the day they ship. Search takes 2 minutes in the field. Medics memorize stale dosing. +3. **Current workflow** — [Agency-specific] screenshot of their existing protocol PDF. Highlight friction points (search, updates, offline access). +4. **PG demo** — Live iPhone screen recording. Voice search → answer in 3 seconds with citation. +5. **Pricing** — Per-seat table. Volume discount tiers. 6-month free pilot offer. +6. **Pilot offer** — What the pilot includes: all medics, protocols loaded, admin panel, weekly check-ins, no cost. +7. **Testimonials placeholder** — Quotes from LACoFD, other pilot agencies (fill in as they come). If empty, use metrics: "1,800 medics, 47K queries/month, 4.8 app-store rating." +8. **Security & HIPAA** — SOC2 Type I target Q3 2026. Data encrypted at rest and in transit. No PHI stored by default. Agency owns their protocol content. +9. **Data ownership** — Agency retains ownership of protocol content. Export-on-demand JSON/CSV. 30-day deletion guarantee on contract termination. +10. **Timeline & next steps** — Week 1: protocols loaded. Week 2: admin training. Week 3: medic onboarding. Week 4+: usage reports. Month 6: renewal conversation. + +--- + +## Objection Handling + +### "What if a medic relies on PG and it's wrong? Who's liable?" + +> "PG is a reference tool, not a replacement for clinical judgment. Every answer cites the source protocol section — the medic is always looking at your agency's approved language. We carry $1M in E&O insurance, but the operational model is identical to the binder: medic uses the reference, medic makes the call. Our medical advisor (currently [Name] at [Institution]) does quarterly QA review of flagged queries." + +### "Where's our data stored? Is it HIPAA-compliant?" + +> "All data is stored in Supabase's US-East and US-West regions. By default PG doesn't store PHI — queries are protocol text, not patient data. For agencies that want audit trails on who looked up what, we offer agency-scoped query logs encrypted at rest. Our security posture doc is at protocolguide.app/security. We're SOC2 Type I this year, Type II next." + +### "What happens in canyon / basement / no-signal calls?" + +> "Every protocol is cached locally on the device after first sync. Medics can work fully offline for up to 30 days without a refresh. Voice search and text search both work offline — the model runs on-device. When connectivity returns, usage logs sync back for the agency admin panel." + +### "We already have [ImageTrend / ESO / custom]." + +> "PG doesn't replace your ePCR — we complement it. ePCRs handle the call; PG is the reference the medic consults during the call. We have direct-link integration with ImageTrend v7+ so a medic can tap a protocol citation and jump from chart to reference without closing the ePCR." + +### "Our medics don't use apps on shift." + +> "That's the most common objection and also the fastest to disprove. We'll instrument the pilot — you'll get weekly usage reports showing queries per medic per shift. If usage is under 3 queries/medic/week by month 3, we'll refund the pilot setup (it's $0 anyway) and walk away. No agency has hit that floor yet." + +### "Why should we go first — who else is using this?" + +> "In CA: LACoFD, [pilot agency 2], [pilot agency 3]. In TX: [pilot agency]. Happy to connect you with any of them — their medical directors are on my reference list. You're not first, but you'd be an early partner and that comes with locked pricing for 3 years." + +--- + +## Cadence + +- **Cold email:** Day 0 +- **Follow-up 1:** Day 7 +- **Follow-up 2:** Day 21 (short, one-line: "Still on your radar?") +- **Move to dropped:** Day 45 with no response +- **Quarterly re-engage:** Dropped agencies get re-contacted every 90 days with a product update angle. diff --git a/docs/business/agency-pipeline-crm-schema.md b/docs/business/agency-pipeline-crm-schema.md new file mode 100644 index 00000000..4f0d41d2 --- /dev/null +++ b/docs/business/agency-pipeline-crm-schema.md @@ -0,0 +1,90 @@ +# Agency Pipeline CRM Schema + +**Owner:** Tanner Osterkamp (CEO) +**Status:** Ready to instantiate +**Last updated:** 2026-04-21 + +--- + +## Tool Choice + +**Primary recommendation: Notion database** (free, shareable, good mobile view for on-the-go updates). + +**Backup: HubSpot Free CRM** if pipeline exceeds 100 agencies or needs email-sync automation. + +Avoid Salesforce / Pipedrive / Airtable paid tiers until pipeline has 200+ contacted agencies and real ARR. + +--- + +## Fields + +| Field | Type | Notes | +|---|---|---| +| `agency_name` | Text | Full legal name, e.g., "Los Angeles County Fire Department" | +| `state` | Select | CA, TX, FL, NY priority; others ok | +| `city` | Text | Primary dispatch city | +| `medic_count` | Number | Field paramedics + EMTs (not admin) | +| `contact_name` | Text | Primary buyer — usually training officer, chief, medical director | +| `contact_email` | Email | Verified via HunterIO or direct confirmation | +| `contact_role` | Select | Training Officer / Chief / Medical Director / EMS Coordinator / Union Rep / Other | +| `outreach_status` | Select | cold / contacted / demo_scheduled / pilot / paid / dropped | +| `last_touch_date` | Date | Most recent outbound email, call, or meeting | +| `next_action_date` | Date | When to follow up; auto-populates based on stage | +| `warm_intro_from` | Text | Name of referrer if warm; blank if cold | +| `deal_value_monthly` | Number | medic_count × $5.99 × (1 - volume_discount); auto-calc | +| `notes` | Long Text | Meeting notes, objections raised, quirks | + +--- + +## Stages & Definition of Done + +| Stage | Enters When | Exits When (DoD) | +|---|---|---| +| **cold** | Added to pipeline | First outbound email sent → `contacted` | +| **contacted** | Email sent, no reply | Reply received + demo call on calendar → `demo_scheduled`

Drug safety warnings [HIGH impact, MEDIUM effort] + +- **Source (Railway):** `server/_core/guardrails/dose-safety.ts:1-362` (`validateDose`, `DoseSafetyResult`), `server/_core/guardrails/dose-ranges.ts:1-499` (`MedicationSafeRange` table, aliases), `server/_core/guardrails/disclaimers.ts:20-55` (`MEDICAL_DISCLAIMERS.medication_dosing`, `.pediatric`). +- **Target:** new `cf-worker/src/guardrails/{dose-safety,dose-ranges,disclaimers}.ts`, invoked from `search.ts` after rerank (pre-merge) and from `agent-api.ts` response shaping. +- **API gotcha:** `dose-ranges.ts` is a pure in-memory table (no I/O) — ports cleanly. `dose-safety.ts` uses plain regex, no Node deps. No Workers gotchas here; keep it V8-pure (no `Buffer`, no `fs`). +- **Migration:** copy both modules verbatim (pure TS, zero runtime deps); attach `doseFlags: DoseSafetyFlag[]` + disclaimer string to `SearchResponse`; surface in tRPC envelope so Expo renders unchanged. +- **Risk:** stale dose table divergence between Railway and Worker — schedule a shared source (e.g. D1 table `dose_safe_ranges` hydrated from Railway export, queried once per request). +- **Parity test:** extend `cf-worker-parity-check.ts` with `testDoseSafety(query="amiodarone 300mg", expectSeverity="safe")` and `testDoseSafety("amiodarone 3000mg", expectSeverity="danger")` against both backends; assert equal `severity` + flag `type`. + +## 2. Adaptive thresholds [HIGH impact, LOW effort] + +- **Source:** `server/_core/rag/quality.ts:118-212` (`THRESHOLD_DESCENT = [null, 0.30, 0.20, 0.10]`, `searchWithAdaptiveThreshold`) + tiered thresholds in `server/_core/rag/config.ts:19-28` (medication 0.35 / procedure 0.30 / general 0.25 / minimum 0.15). +- **Target:** new `cf-worker/src/adaptive.ts`; replace hard-coded `MIN_SCORE = 0.5` at `cf-worker/src/search.ts:21`. +- **API gotcha:** Workers disallow recursive unbounded loops near CPU-time limit (50ms free / 30s paid). Cap descent at 4 attempts; each retry re-queries Vectorize (cheap, ~30ms) — do **not** re-embed. +- **Migration:** port `THRESHOLD_DESCENT` + loop body; intent classification (`medication`/`procedure`/`general`) derives from existing `normalize.ts` output; thread `initialThreshold` into `PROTOCOL_VECTORS.query` filter. +- **Risk:** Vectorize `query()` doesn't support server-side score threshold — we filter in JS; ensure `topK` is bumped to 40 on retry so low-threshold pass sees enough candidates. +- **Parity test:** `testAdaptive(query="obscure pediatric drug X")` — assert both backends return same `thresholdUsed` + `adapted=true`. + +## 3. Custom re-ranking [HIGH impact, LOW effort — mostly done] + +- **Source:** `server/_core/rag/scoring.ts:1-444` (`advancedRerank`, `applyContextBoost`), multipliers table at `server/_core/rag/config.ts:92-196` (20+ named multipliers: `providerImpressionPenalty`, `pedsRefusal1200_2Boost`, `bareProtocolNumberBoost`, `bridgeChunkPenalty`, `pediatricWeightBased1309Boost`, etc.). +- **Target:** `cf-worker/src/rerank.ts:1-252` (partial port exists — ported patterns but **missing the `RAG_CONFIG.rerank.multipliers` table**). +- **API gotcha:** multipliers are pure numeric constants — straight copy. The Worker port hard-codes subset at call sites instead of a centralized table; that drifted on 2026-04-21 (see `config.ts:183,190` — `bareProtocolNumberBoost`, `bridgeChunkPenalty` added post-port). +- **Migration:** extract `cf-worker/src/rerank-config.ts` mirroring `RAG_CONFIG.rerank`; refactor `rerank.ts` to read multipliers from that single object; add ESLint rule forbidding magic numbers in `rerank.ts`. +- **Risk:** silent ranking drift — this is why iOS Build 40 returned Ref 215 for "814 policy" on Railway before the bare-number boost landed; Worker must not regress. +- **Parity test:** `testRerankOrder(queries=["814 policy","amiodarone 5kg pediatric","base contact chest pain"])` — assert identical top-3 `protocolNumber` order vs Railway; fail on any reorder. + +## 4. Multi-query RRF fusion [MEDIUM impact, MEDIUM effort] + +- **Source:** `server/_core/rag/search-execution.ts:77-134` (`multiQueryFusion`), `server/_core/rag/scoring.ts:400-444` (`reciprocalRankFusion`, `RRF_K = 60`), `server/_core/ems-query-normalizer.ts:357` (`generateQueryVariations`). +- **Target:** new `cf-worker/src/fusion.ts`; opt-in flag `enableMultiQueryFusion` on `SearchRequest`. +- **API gotcha:** Railway runs variations **concurrently** via `Promise.all`. On Workers, subrequests are free but each variation = 1 embedding call (+200ms) + 1 Vectorize query. Use `waitUntil` only for non-blocking; keep variations in the request path with `Promise.all`, bounded to 3 variations, 600ms total budget (vs Railway's 2s). +- **Migration:** port `generateQueryVariations` + `reciprocalRankFusion` (both pure); call from `search.ts` when `req.enableMultiQueryFusion === true` or when `normalizedQuery` classifies as medication intent. +- **Risk:** Gemini embedding rate-limit (1500 RPM) — 3x amplification at peak could throttle; add short-circuit if first variation returns ≥ `RAG_CONFIG.quality.minQualityResults` high-quality hits. +- **Parity test:** `testFusion(query="epi dose anaphylaxis pediatric", enableMultiQueryFusion=true)` — assert same top-5 ids + within 50ms RRF-score delta. + +## 5. Caching [MEDIUM impact, LOW effort — scaffolded] + +- **Source:** `server/_core/rag/cache.ts:1-118` (`QueryCache` in-memory LRU + `embeddingVersion` flush), `server/_core/cache/agency-cache.ts:1-40` (2-tier memory + Upstash Redis), `server/_core/cache/cache-config.ts` TTLs. +- **Target:** `cf-worker/src/cache.ts` already defines TTL constants + SHA-256 keying (`cache.ts:19-167`) but is **not invoked from `/api/search` or `/api/protocol/:id`**. +- **API gotcha:** no in-process Map survives across requests (isolate recycling). Use `caches.default` (Cache API) for response-level caching keyed by canonical URL, and Workers KV for structured data (`query_hash → ResultList`). Cache API entries are per-colo; KV is global (eventual). Do **not** attempt Upstash REST from Workers when KV works — extra RTT. +- **Migration:** wire `cache.ts:CACHE_TTL.SEARCH` into `index.ts:106` search handler before invoking `handleSearch`; bind `PROTOCOL_CACHE` KV namespace in `wrangler.toml`; key = sha256(`${normalizedQuery}:${agencyId}:${embeddingVersion}`). +- **Risk:** stale results after protocol ingest — include `embedding_version` + latest `manus_protocol_chunks.created_at` max in cache key (same invalidation signal as `QueryCache.checkVersion`). +- **Parity test:** `testCacheHit(query X 2x in a row)` — assert second call has `fromCache=true` and `latencyMs` < 100ms on Worker. + +## 6. Rate limiting [MEDIUM impact, MEDIUM effort] + +- **Source:** `server/_core/rateLimitRedis.ts:1-234` (Upstash-backed, per-tier: `TIER_LIMITS.search.free = 30/min`, pro 100, premium unlimited), tier resolved from `req.user.subscriptionTier`, fallback to in-memory `server/_core/rateLimit.ts:20-33` (free 5/day, pro 100/day, unlimited). +- **Target:** new `cf-worker/src/rate-limit.ts` + Durable Object `cf-worker/src/durable/RateLimiterDO.ts`. +- **API gotcha:** no Express middleware, no shared Redis client. Cloudflare options: (a) Durable Object with sliding-window counter (strong consistency, costs extra), (b) built-in `@cloudflare/workers-types` Rate Limiting API (`env.RATE_LIMITER.limit({key})` — GA Jan 2026, simpler, less precise), (c) KV-backed counter (cheap, eventually-consistent — not safe for hard caps). Pick (b) for tier-agnostic IP throttle, (a) only for per-user daily caps. +- **Migration:** bind `[[unsafe.bindings]] type="ratelimit"` in `wrangler.toml` for (b); Hono middleware reads `X-Agent-Key` or Clerk JWT sub for user id, falls back to `CF-Connecting-IP`. +- **Risk:** Workers Rate Limiting API is per-zone, not per-user — per-tier daily caps need a DO. Start with IP throttle on `/api/search`; defer per-user daily cap until Clerk auth lands (Phase 3 per `index.ts:20`). +- **Parity test:** `testRateLimit(31 requests in 60s from one IP)` — assert 31st call returns 429 on both backends with same `Retry-After` semantics. + +## 7. Observability [LOW impact, LOW effort] + +- **Source:** `server/_core/monitoring/sentry.ts:1-28`, `server/_core/tracing.ts:1-426` (OpenTelemetry spans: `rag.search`, `rag.rerank`, `rag.fusion`), `server/_core/logger.ts:1-167` (pino structured logs). +- **Target:** `cf-worker/src/observability.ts` (new), Analytics Engine binding in `wrangler.toml`. +- **API gotcha:** no pino, no OTel SDK on Workers (no async-hooks). Use: (1) `@sentry/cloudflare` for errors (native Workers support, no subprocess), (2) Workers Analytics Engine binding (`env.ANALYTICS.writeDataPoint`) for custom metrics (query latency, threshold used, cache hit rate), (3) Workers Logs (Logpush to R2 / Axiom) for structured console lines — same Axiom destination as Railway's Locomotive template. +- **Migration:** add Sentry init in `index.ts`; wrap search handler with `Sentry.withScope`; emit Analytics Engine data points for `rag_search` with dims `{agencyId, thresholdUsed, cacheHit, latencyMs, resultCount}`; switch `console.log` calls to structured JSON so Logpush parses cleanly. +- **Risk:** Analytics Engine has 25 dims/100 blobs per data point — plan schema now. Sentry cost: Workers plugin bills per transaction; sample 10%. +- **Parity test:** `testObservability(cause intentional 500)` — assert both Railway and Worker Sentry projects receive the event with matching `transaction` + `tags.agency_id`. + +--- + +## Execution order & rollout + +1. Steps 1–3 land first (safety, thresholds, rerank parity) — ship behind shadow traffic from `cf-worker-parity-check.ts` nightly run. +2. Step 4 after #3 proves stable (fusion amplifies ranking bugs). +3. Steps 5–6 together (caching + rate-limit both want KV + DO bindings; single `wrangler.toml` diff). +4. Step 7 last — observability confirms prior steps are behaving before cutover decision. + +**Cutover gate:** `cf-worker-parity-check.ts` green on all 7 suites for 7 consecutive nights → flip 1% iOS traffic via Netlify edge rewrite → graduate weekly (1 → 10 → 50 → 100%). No iOS app rebuild required (same tRPC envelope, same URL surface under a different host). + +**Non-goals for this plan:** Clerk JWT auth middleware (separate Phase 3 plan), ingestion pipeline port (Railway stays authoritative writer), admin endpoints.

charset=UTF-8 Content-Transfer-Encoding: 8bit Three new offline-capable clinical agents for the Tools tab: Burn Assessment (/tools/burn) — Rule of 9s (adult) or Lund-Browder (peds, age-banded) TBSA with Parkland fluid calc (4 mL × kg × %TBSA; half in first 8h, adjusted for elapsed injury time) and ABA burn-center transport tier. Pure-function utilities; zero network calls. Toxidrome Recognition (/tools/toxidrome) — Maps HR / BP / RR / temp / pupils / skin / mental status / bowel sounds / rigidity / clonus / hyperreflexia to the classical toxidromes (opioid, sympathomimetic, anticholinergic, cholinergic, sedative-hypnotic, serotonin syndrome, NMS, hallucinogen) with rule-table scoring, confidence tier, differential list, and treatment recommendations. Differentiates serotonin (clonus) from NMS (rigidity). Med Interaction Checker (/tools/med-interaction, Pro, AI) — 20-drug EMS catalog + 50-drug home med pick list with brand-alias normalization and free-text parser (PHI redacted). Curated rule table covers must-catch dangerous combinations: MAOI+epi, PDE5+nitroglycerin, benzo+opioid, warfarin+aspirin, SSRI+ondansetron, beta-blocker+albuterol, amiodarone+ digoxin, epi+TCA, opioid+MAOI, and more. Severity-sorted with mechanism and recommendation. tRPC `tools.medInteraction.check` with rate limit. 77 new unit tests covering full-body Rule of 9s = 100%, infant head Lund-Browder = 19%, Parkland 70kg×20% = 5600mL / 2800mL first 8h, ABA triage (adult 15%, peds 12%, inhalation override), opioid / sympathomimetic / cholinergic / serotonin / NMS recognition, and every must-catch interaction pair. All pass. Appends three cards to the Tools tab (Burn=error/Offline, Toxidrome=warning/Offline/ALS, MedInteraction=primary/AI/Pro). Does not modify the existing 15 tool cards. --- app/(tabs)/tools.tsx | 32 ++ app/tools/burn.tsx | 76 ++++ app/tools/med-interaction.tsx | 76 ++++ app/tools/toxidrome.tsx | 76 ++++ components/tools/burn/BurnAssessment.tsx | 428 ++++++++++++++++++ components/tools/burn/burn-utils.ts | 351 ++++++++++++++ .../med-interaction/MedInteractionChecker.tsx | 274 +++++++++++ .../med-interaction/interaction-utils.ts | 426 +++++++++++++++++ components/tools/toxidrome/ToxidromeAgent.tsx | 334 ++++++++++++++ components/tools/toxidrome/toxidrome-utils.ts | 276 +++++++++++ server/routers.ts | 2 + server/routers/tools/index.ts | 1 + server/routers/tools/med-interaction.ts | 192 ++++++++ tests/burn-utils.test.ts | 254 +++++++++++ tests/med-interaction-router.test.ts | 215 +++++++++ tests/toxidrome-utils.test.ts | 155 +++++++ 16 files changed, 3168 insertions(+) create mode 100644 app/tools/burn.tsx create mode 100644 app/tools/med-interaction.tsx create mode 100644 app/tools/toxidrome.tsx create mode 100644 components/tools/burn/BurnAssessment.tsx create mode 100644 components/tools/burn/burn-utils.ts create mode 100644 components/tools/med-interaction/MedInteractionChecker.tsx create mode 100644 components/tools/med-interaction/interaction-utils.ts create mode 100644 components/tools/toxidrome/ToxidromeAgent.tsx create mode 100644 components/tools/toxidrome/toxidrome-utils.ts create mode 100644 server/routers/tools/med-interaction.ts create mode 100644 tests/burn-utils.test.ts create mode 100644 tests/med-interaction-router.test.ts create mode 100644 tests/toxidrome-utils.test.ts diff --git a/app/(tabs)/tools.tsx b/app/(tabs)/tools.tsx index fedb2173..54c14b3b 100644 --- a/app/(tabs)/tools.tsx +++ b/app/(tabs)/tools.tsx @@ -200,6 +200,38 @@ const TOOLS: ToolDef[] = [ accentKey: "warning", badge: "Offline", }, + { + id: "burn", + title: "Burn Assessment", + description: + "Rule of 9s (adult) or Lund-Browder (peds) TBSA with Parkland fluid calc and ABA burn-center transport tier.", + icon: "flame.fill", + route: "/tools/burn", + accentKey: "error", + badge: "Offline", + }, + { + id: "toxidrome", + title: "Toxidrome Recognition", + description: + "Match patient presentation (HR, BP, pupils, skin, mental status, bowel sounds) to a classical toxidrome and get recommended treatment.", + icon: "pills.circle.fill", + route: "/tools/toxidrome", + accentKey: "warning", + badge: "Offline", + requiresAls: true, + }, + { + id: "med-interaction", + title: "Med Interaction Checker", + description: + "Patient's home med list + proposed EMS drug → interactions and contraindications flagged by severity.

Scrolling a 120-page PDF while the patient is in front of you takes 45 to 90 seconds. That is 45 to 90 seconds you do not have.\n\nHOW PROTOCOL GUIDE FIXES IT\n• Speed — Ask a question by voice or text, get the answer in 2 seconds.\n• Jurisdiction — 2,738 LEMSAs mapped. Your agency scopes every answer. LA County protocols for LA County medics, not a generic national cheat sheet.\n• Offline — Cached protocols load with no signal. Works in basements, rigs, and dead-zone calls.\n\nFEATURE PILLARS\n• Voice search — hands-free lookup while you are moving, driving, or gloved up.\n• Paramedic drug dosing — adult, pediatric weight-based, route, and contraindication shown together.\n• Source citations — every answer links to the originating protocol number and revision year.\n• Agency picker — 2,738 LEMSAs ready, your answers scoped to the one you work for.\n• Offline mode — service-worker cache keeps the protocols you need loaded.\n\nSAFETY\nThis is a reference tool. Always follow your agency's medical direction. Not a substitute for clinical judgment. Every response includes a \"verify with your local protocols\" affordance.\n\nWHO IT IS FOR\nParamedics. EMTs. Firefighter-paramedics. Flight medics. EMS educators. Paramedic students preparing for the national registry or a license exam. Anyone who needs a fast, accurate EMS field guide.\n\nJURISDICTIONS\nLA County DHS — live. California statewide — in progress. National expansion — on the roadmap.\n\nPRICING\n• Free — 5 queries per day, 1 agency.\n• Pro — $9.99/month or $89/year.
