Pharmacopedia extension specification

Version: 0.9.5 · Requires: MediaWiki >= 1.46.0 · PHP >= 8.5 Author: MDElliottMD · License: GPL-2.0-or-later Source: /var/www/mediawiki/extensions/Pharmacopedia/

The Pharmacopedia extension turns a MediaWiki install into a structured, community-edited medicine reference with rich user-profile, assessment, life-story, and visibility-sharing infrastructure. It adds parser tags, special pages, API modules, a chip-picker / autosave UI framework, a vis-timeline-based visual life timeline, a granular per-record sharing subsystem, and a database schema that together support:

  • Structured medicine pages via the {{MedTemplate}} template
  • Per-user rating on effects, problems, titration strategies, anecdotes, and drug-drug interactions (continuous 0–100 sliders, ±100 valence; no 0–5 likert anywhere)
  • Binary AND choice/multi voting on arbitrary content (type="single" / type="multi" with 2-5 options, results-visibility policy per element)
  • Two-perspective data capture (personal vs. provider) wherever clinically meaningful
  • User profile with dimensional personality / autism assessments (CATI, CAT-Q, MBTI, Enneagram, PID-5-BF, OCEAN/BFI-10) and rich auto-generated reports
  • Diagnosis autocomplete backed by ~41,500 ICD-10-CM, ICD-11, and DSM-5 codes
  • Life-story timeline: visual swimlanes (vis-timeline 7.7.3, vendored Apache-2.0) plus a synchronized trait-trajectory overlay (vis.Graph2d); card-list view alongside; quick-add free-text observation parser; range-date episode form with severity slider
  • Per-record sharing subsystem: rule types include public, private, users, cohort, link_token, reciprocal; time-bounded; audit log of who-viewed-what; bulk free-text → structured ref upgrader; privacy mode that disables legacy fallback
  • Chip-picker / autosave / slider-precise-input UI framework shared across editor surfaces
  • Date + time + range kit: PCPDatePicker (point/range/possibility), PCPTimePicker (fuzzy time-only: "4p", "noon", "quarter past 6")
  • Verified-provider role with document-based verification
  • Fail-closed ClamAV scan on every image / file upload (hard project rule)
  • Per-user research_id (stable 10-char hex, opaque, never reassigned) for de-identified research participation

Precision doctrine

A standing design rule (memorialised 2026-05-17) that shapes every storage / UI decision in the extension:

  • No bucketing where a number or free-text will do. Income is numeric + currency, not a 5-band dropdown. Education keeps the bucketed dropdown and adds numeric years of schooling + free-text field of study.
  • No single-select where multi-select reflects reality. Languages, gender identities, ethnicities, pronouns, religion, marital status, stop-reasons, all use chip-pickers (with optional severity per chip where relevant).
  • No forced category where a continuous score works. All assessments (Enneagram 9 type sliders, MBTI 4 dichotomy sliders, OCEAN 5 trait sliders, CATI/CAT-Q/PID-5-BF items) use continuous 0–100 sliders, never radio buttons or button rows. Valence is ±100, not ±3.
  • Storage in canonical form, UI converts at display. Heights stored cm regardless of user's preferred unit (cm or ft+in); ICD codes stored as ISO; date capture as range / possibility-mix JSON.
  • Browser auto-fill as suggestion only. Country chip pre-fills from navigator.language; languages from navigator.languages; time zone from Intl.DateTimeFormat().resolvedOptions().timeZone. User can always edit or remove.
  • Always allow custom free-text where the curated list might miss someone. Chip-pickers accept Enter-to-add custom chips for all picklists except ISO-coded ones (country, language).

High-level architecture

  • Backend (PHP): includes/, one class per parser tag, store, special page, or API module. Auto-loaded under MediaWiki\Extension\Pharmacopedia\. Assessment classes under includes/Assessments/. API modules under includes/Api/.
  • Frontend (JS): multiple ResourceModules per surface area:
    • ext.pharmacopedia: main IIFE (chip-picker, dx autocomplete, BFI-10 compute, vote logic for both binary and choice/multi)
    • ext.pharmacopedia.blocksave: debounced autosave per block (race-safe)
    • ext.pharmacopedia.datepicker: range / possibility-mix date widget
    • ext.pharmacopedia.timepicker: time-only widget (fuzzy parsing, extracted from DatePicker)
    • ext.pharmacopedia.share: per-record share dialog (People / Link / Cohorts tabs)
    • ext.pharmacopedia.observation: quick-add observation textarea + live preview
    • ext.pharmacopedia.refupgrade: bulk linker for free-text → structured refs
    • ext.pharmacopedia.vis-timeline-vendor: vis-timeline 7.7.3 (vendored)
    • ext.pharmacopedia.lifetimeline: visual life-story timeline + swimlanes + toolbar
    • ext.pharmacopedia.lifegraph: trait-trajectory overlay (vis.Graph2d) synced to timeline
    • ext.pharmacopedia.kitsync: glue that propagates kit-widget changes into legacy hidden inputs + drives privacy-mode toggle
  • Styles (CSS): shared dark-theme palette (black / dark-grey / purple / white primary; red / green / blue / teal sparingly for semantic distinction).
  • Schema: sql/, ~25 core tables plus migration patches. Picked up via LoadExtensionSchemaUpdates hook.

Parser tags

Registered via Hooks::onParserFirstCallInit:

Tag Purpose Class
<vote> after-vote\|hidden" for tally-visibility policy. VoteTag
<effect> Therapeutic or adverse effect; patient + provider perspectives; provider freq slider 0–100; shared valence slider ±100 EffectTag
<discuss> Threaded comment widget CommentTag
<effectsummary> Roll-up aggregate header EffectSummaryTag
<titration> Titration strategy card with up/down vote TitrationTag
<anecdote> Personal or provider story with up/down vote AnecdoteTag
<problem> A problem (formerly "indication") the medicine addresses; 0–100 efficacy likert slider + "don't know" toggle ProblemTag
<pharmaInteractions/> Self-closing; renders the Interactions section for the current page InteractionTag
<pharmaExperience/> Self-closing; renders the Experience report form (efficacy, burden, dose, route, schedule, stop-reasons) ExperienceTag

All non-self-closing tags take a slug argument and (where relevant) a title, label, author, ref, or perspective.

Tag wikitext examples

<problem slug="depression" title="Major depressive disorder"
  author="MDElliottMD">First-line for moderate to severe MDD.</problem>

<effect slug="nausea" label="Nausea"/>

<effect ref="hyperkalemia"/>   <!-- ref to global effect library -->

<titration slug="slow-start-elderly" title="Slow start (elderly)"
  author="MDElliottMD">Begin at 10 mg q AM; titrate by 10 mg every 14 days.</titration>

<anecdote slug="qi8sg2" perspective="provider"
  author="MDElliottMD">One patient developed serotonin syndrome at week 3...</anecdote>

<pharmaInteractions/>
<pharmaExperience/>

<vote slug="fav-color" type="single" options="Red; Blue; Green">
What's your favorite color?</vote>

<vote slug="side-effects" type="multi" results="after-vote"
  options="Dry mouth; Insomnia; Anxiety; Headache; None">
Which side effects did you experience?</vote>

Voting / rating semantics

Element Scale Perspectives Storage
Vote tag (binary) +1 / −1 binary single pcp_votes.v_value
Vote tag (single-choice) one of 2-5 options single pcp_votes.v_choices (CSV index)
Vote tag (multi-choice) any subset of 2-5 options single pcp_votes.v_choices (CSV indices)
Titration +1 / −1 binary single pcp_votes
Anecdote +1 / −1 binary single (perspective is metadata) pcp_votes
Problem (efficacy likert) 0–100 continuous slider, optional "Don't know" (-1) single pcp_likert_reports
Effect (patient) experienced ∈ {yes, no, unsure} + valence ±100 slider patient pcp_effect_reports (perspective=1)
Effect (provider) frequency 0–100 continuous slider + "Don't know" (-1) + valence ±100 slider provider pcp_effect_reports (perspective=2)
Interaction experience 1–5 + valence ±100 slider + optional note user + provider, separate aggregates pcp_interaction_reports

Choice / multi vote elements expose per-option tallies via tallyChoices() on demand. Per-option bars render inline in the picker. The results attribute gates tally visibility:

  • live (default) — tally always visible
  • after-vote — tally hidden until viewer has voted
  • hidden — tally never shown (only options + "thanks" on submit)

Server-side options-hash (ve_options_h) detects post-vote option-list edits; the API rejects new votes whose submitted hash doesn't match the live one. Voter identities are stored as HMAC-SHA256 (v_voter_hash) so admins reading the DB cannot map votes to user accounts without the HMAC secret.

Server-side aggregates: n, mean of the rating field, and (for interactions) severe = (vmean ≤ −83.0) (rescaled from the original ±3-scale −2.5). Aggregates are recomputed and returned by every report-submit API call so the row re-renders in place without a page reload.

Effect bucketing

When a wiki <ul> contains only <effect> cards, JavaScript groups them into buckets by the provider frequency mean (data-fmean):

Bucket fmean band Default state
Common > 20 expanded, always visible
Uncommon > 5 and ≤ 20 collapsed
Rare ≤ 5, provider vmean > −83 collapsed
Rare but Severe ≤ 5 and vmean ≤ −83 expanded by default, red highlight
Not yet rated no provider data (n=0) collapsed, only renders if non-empty

The vmean ≤ −83 threshold is also the trip-wire for the "severe" red treatment on interaction rows.

User profile

Special:MyProfile is the user-facing editor for everything personal. Every block on it autosaves on a 800 ms debounce (see Autosave infrastructure).

Visible at top: a Privacy-mode panel toggling whether legacy public fallback applies (privacy-mode ON = only explicit share rules grant access; OFF = the field-level pf_visibility enum applies).

🔗 Share chips appear in each fieldset legend (Demographics, Diagnoses, Medicines) so the owner can scope a share-rule to that namespace via the modal Share dialog.

Block list

  • Identity (display alias, default attribution, experience-report visibility, read-only Research ID badge)
  • Demographics (full chip-picker rebuild, see below)
  • Personality (Big Five OCEAN sliders + collapsible assessments)
  • Enneagram (9 type sliders + 45-item screening test)
  • MBTI (4 dichotomy sliders + 32-item OEJTS test)
  • Personality / autism assessments (PID-5-BF, CATI, CAT-Q, each as a collapsible inline test)
  • Diagnoses (multi-row with ICD-10-CM + ICD-11 autocomplete, severity slider 0–100, disability slider 0–100, status, origin, dates, notes)
  • Medicines I have tried (multi-row with med-name autocomplete, dose, route 16-option dropdown, schedule with datalist suggestions, efficacy + burden sliders 0–100, periods via date-picker)

Demographics (chip-picker / structured-widget rebuild)

All categorical demographics use the chip-picker widget (single or multi, with optional primary marker, optional custom free-text). All quantitative demographics use numeric inputs or structured composite widgets.

  • Birthday DatePicker (single / range / possibility-mix). Setting (or changing) the birthday auto-syncs a TYPE_STORY life event tagged auto-birth titled 'Born!' on the life-story timeline. Subsequent birthday edits move ONLY the event's date; user edits to title, body, tags, images are preserved.
  • Sex assigned at birth single-select (clinical category)
  • Gender identity multi-select chip-picker, 27 common terms + custom
  • Pronouns multi-select chip-picker, 17 common sets + custom
  • Ethnicity / race multi-select chip-picker, 23 broad categories + custom
  • Country of residence chip-picker single-value, ISO 3166 list (~100 entries), auto-suggested from navigator.language
  • Languages chip-picker multi-select with ★ primary marker, ISO 639-1 list (~70 entries with endonyms), auto-suggested from navigator.languages
  • Height / weight unit toggle (Metric cm/kg or US ft+in/lb); stored canonically as cm/kg regardless
  • Handedness single-select (3 options)
  • Smoking structured widget: status + cigs/day + years smoked + quit date (PCPDatePicker); auto-computes pack-years
  • Alcohol structured widget: drinks/week + typical drink type + max one occasion
  • Education bucketed highest-level + numeric years + free-text field of study
  • Employment bucketed status + free-text occupation + numeric hours/week
  • Income numeric amount + currency selector (20 options) + individual/household scope
  • Marital / relationship status chip-picker single + custom
  • Religion / spirituality chip-picker single + custom, 36 traditions + secular stances
  • Housing chip-picker single + custom
  • Number of children numeric
  • Time zone free text, auto-detects IANA TZ on first load if empty
  • Chronotype / sleep schedule two PCPTimePicker widgets (typical bedtime, typical wake; fuzzy parsing accepts "10p", "bedtime", "quarter past 6")
  • Political orientation two-axis compass sliders (economic ±100, social ±100)

Diagnosis subsystem

Diagnoses are stored in pcp_profile_diagnoses with autocomplete backed by pcp_diagnosis_abbreviations (~41,500 rows):

System Rows Notes
ICD-10-CM 25,542 CMS FY2026 valid-codes file, chapters A B C D E F G H I J K L M N O P Q R U + 553 friendly-alias rows (mdd, adhd, stroke, htn, etc.)
ICD-11 15,823 WHO MMS Apr 2026 linearization, chapters 01–24 except billing (22) / external causes (23) / extension modifiers (X) / functioning assessment (V) + 361 friendly-alias rows
DSM-5 32 Legacy hand-seed for codes without ICD equivalents
Other 34 somatic, unofficial, ICD-10 (WHO), instrument

Skipped intentionally: ICD-10-CM S/T (injury body) ~41k codes, V/W/X/Y (external causes) ~7.5k codes; ICD-11 chapter 22 (injury), 23 (external causes), 25 (special purposes), V (functioning scales), X (17.7k extension modifiers). These are billing scaffolding, not diagnoses.

Autocomplete via action=pharmacopediadxsearch, multi-token AND search (e.g. "ADHD inattentive" matches the F90.0 row that contains both substrings); ORDER BY FIELD(da_system, 'ICD-10-CM', 'ICD-11', 'DSM-5', ...) so ICD-10-CM leads, then ICD-11, then everything else.

Personality / autism assessments

Six assessments, all with continuous-slider items, "Not sure" toggle per item, auto-computed subscale + total scores, and a rich auto-generated report at Special:MyAssessment/{key}:

Assessment Items Score range Cutoffs / threshold Report
CATI 42 (6 subscales) 1–5 per item, sum per subscale 148 / 139 / 141 / 156 (English 2025 gender-specific) gender-specific scoring against English 2025 normative tables (12,253-row CatiNorms.php from OSF supplementary)
CAT-Q 25 (3 subscales) 1–7 per item, sum per subscale Total ≥ 110 + per-subscale cutoffs (NeurodivUrgent recalibration) subscale narratives, top-item analysis
PID-5-BF 25 (5 domains) 0–3 per item, mean per domain mean ≥ 2.0 per domain domain narratives, cross-system mapping (DSM-5 AMPD ↔ ICD-11 PD ↔ Big Five)
MBTI 32 OEJTS items + 4 direct dichotomy sliders ±2 per axis none (dimensional treatment, no forced categorisation) 4-axis Position column with letter + strength + bar, cognitive function stack, Big Five mapping, top-item analysis
Enneagram 45 (5 per type × 9 types) 0–100 per type none (no clinical cutoffs for typology) hero banner (primary + wing + tritype), 9-bar profile, primary deep-dive, wing analysis, centers, Hornevian + Harmonic groups, stress / growth lines, cross-system map (Big Five, MBTI)
OCEAN (Big Five) 5 direct sliders + optional BFI-10 (10 items) 0–100 per trait none (personality, not pathology) trait deep-dives (high / mid / low at your score), BFI-10 item table, cross-system mapping (MBTI ↔ Enneagram ↔ PID-5-BF) pulling live data from the profile

All assessment items submit raw responses to pcp_profile_fields under namespace {key}_raw (e.g. cati_raw); the computed scores live under namespace {key} with keys like subscale_SOC, total, plus a taken_at timestamp. Re-scoring happens automatically on every save (autosave fires scoreResponses() on the full raw set, skipping "unsure" rows). Each completed assessment also auto-upserts a Life-story keyframe row (see Life-story timeline) so trajectories plot over time.

Life-story timeline

Special:MyLifeStory is the owner-facing editor + viewer for everything time-anchored about the user. Backed by pcp_life_events with extension columns for episode / observation / keyframe metadata.

Event types

le_type Meaning Notes
0 (TYPE_STORY) Plain timeline entry title, body, optional image
1 (TYPE_IMAGE) Image-primary entry same shape, image is the main payload
2 (TYPE_KEYFRAME) Auto-created assessment snapshot populated by upsertAssessmentKeyframe on every assessment save
3 (TYPE_OBSERVATION) Plain-text observation created via the quick-add textarea; parser extracts date, polarity, refs
4 (TYPE_EPISODE) Time-bounded period start + end (PCPDatePicker range mode); type / subtype / severity 0-100

Quick-add observation

A textarea at the top of Special:MyLifeStory (and a 📝 modal trigger on Special:MyProfile) accepts plain text like: 

anxiety from bupropion in jan 2020
did not experience anxiety from bupropion in feb 2018
panic attack 2 months ago
depressed as a freshman
i had a manic episode sep 1 2020 till nov 15 2020
no insomnia while on melatonin in summer 2023
felt great on christmas 2020
happiest on my 30th birthday

ObservationParser::parse() extracts:

  • Date (point or range): ISO, MM/DD/YYYY, "Month D YYYY", "Month YYYY", "Season YYYY", "early/mid/late YYYY", bare year, decades ("2010s"); date RANGES via "X to Y", "X till Y", "from X to Y", "X - Y"; relative-to-now ("yesterday", "last week/month/year", "N months ago", "a few weeks ago"); holidays (christmas, halloween, new year's, valentine's, july 4th, thanksgiving with computed 4th-Thursday-of-Nov, MLK / Memorial / Labor day); age-relative ("7y8mo", "51.2yo", "at age 14", "ages 2-10"); life stages ("in childhood", "as a teen", "as a freshman", "junior year"); Nth birthday ("my 30th birthday")
  • Polarity (negation detection): "not", "didn't", "did not experience", "never", "without", "denied" → polarity=0 (negative); else 1 (positive)
  • Leading verbs stripped: "I was diagnosed with", "I took", "started taking", "tried", "was on", "experienced", "felt" — so the subject is the noun, not the verb
  • Adverbs stripped: "briefly", "occasionally", "frequently", "sometimes", "always" — so the subject is the noun, not the modifier
  • Role splitting: "from / caused by / due to / while on" → role='cause'; "with / during / while" → role='context'
  • Ref resolution, in priority order:
    1. User's meds (pcp_user_meds)
    2. Wiki pages in Category:Medicines
    3. Effects catalog (pcp_effects)
    4. Problems catalog (pcp_problem + pcp_problem_alias)
    5. User's diagnoses (pcp_profile_diagnoses)
    6. Global ICD diagnosis abbreviations (pcp_diagnosis_abbreviations)
    7. Free-text fallback (stored as type='free' for later upgrade)
  • Auto-promote unrecognized subjects to custom-trait keyframes: when the subject doesn't match an existing entity but the input has BOTH a numeric value AND a date (e.g. my neuroticism was 5 at 10yo), the subject is treated as a NEW custom trait (namespace='custom', key derived from subject text). Creates a TYPE_KEYFRAME event with the value + a trajectory point. Future inputs with the same subject auto-append to that series.
  • Flexible range separators: X to Y, X through Y, X thru Y, X until Y, X till Y, em-dash, en-dash, flexible-whitespace hyphens (digit-aware so 2026-05-31 ISO dates aren't split), .. / ... ellipsis.
  • Age-range phrases without literal "ages": when I was 11-13, from 11 to 13, between ages 5 and 12, aged 10 to 14. Negative lookahead prevents false matches on dosages (10-20 mg), durations (5-10 years ago), measurements (cm/mm/ft/lb/etc).
  • Episode-shape detection: "manic episode" → type=mood, subtype=manic; "psychotic break", "panic attack", "anxiety attack", "trauma response" all route to addEpisode instead of addObservation. A date RANGE alone is enough to force is_episode=true.

Live preview chips appear under the textarea as you type. Submit routes to pharmacopediaobservation API which writes the row + refs via setEventRefs().

Episode form

Click the "🌀 Episode" button (or the quick-add detects an episode shape) for the structured form:

  • Type selector: mood / psychotic / anxiety / panic / trauma response / dissociative / substance use / eating / sleep disturbance / pain flare / migraine / medication adjustment / hospitalization / creative surge / spiritual / transcendent / relationship crisis / grief / somatic / other
  • Subtype (text + datalist) — for mood: depressive / manic / hypomanic / mixed / dysphoric / euthymic
  • Severity slider 0-100 (per precision doctrine)
  • Date range via PCPDatePicker locked to range mode
  • Title, body, single virus-scanned image, visibility (4-state)

Visual timeline

Top of Special:MyLifeStory has a tabbed view: Visual timeline (default) / Card list.

The visual timeline uses vis-timeline 7.7.3 (vendored Apache-2.0 at resources/vendor/vis-timeline/) with these features:

  • Swimlanes (toggleable chips): Episodes (range bars), Events, Observations, Keyframes (off by default), Derived
  • Trait-trajectory overlay: a synchronized vis.Graph2d draws smooth (centripetal Catmull-Rom interpolated) lines for every keyframe trait series (CATI subscales, PID-5-BF domains, CAT-Q, custom traits like "shyness") DIRECTLY on top of the timeline plot area. Same X-axis; the graph's data + time axes are CSS-hidden so only the lines + points show. Values are normalized to 0-100% within each series so different scales coexist.
  • Toolbar: Visual/Card tabs, group toggle chips, magnifier + zoom +/- buttons, Fit visible / Fit everything
  • Plain wheel = vertical scroll inside the timeline (520px fixed height); Ctrl+wheel = zoom; Shift+wheel = horizontal pan
  • Click empty timeline area: prefills the quick-add textarea with "on YYYY-MM-DD" at that date + scrolls + triggers live preview
  • Click an item: routes to its edit form (event / episode / observation, each has its own route)
  • Collapsible "Trait series (N)" legend with chip toggles to show/hide individual series

Edit / delete / duplicate flows

Each event type has its own edit route under Special:MyLifeStory:

  • Special:MyLifeStory/edit-observation/<id> — re-parses raw text on save; supports polarity override + date override
  • Special:MyLifeStory/edit-episode/<id> — full episode form
  • Special:MyLifeStory?edit_event=<id> — existing event / image / keyframe form

All three forms have side-by-side "Delete X" + "Duplicate X" buttons. Duplicate copies fields + refs + keyframe traits (NOT images) and redirects to the new row's edit form.

When the parser stored a free-text ref (because the entity wasn't in the user's data at the time), Special:MyRefLinks finds all such refs and offers one-click "link to {match}" buttons. Matches come from the same catalogs the parser checks at write time. A banner on Special:MyLifeStory ("📎 N free-text references could be linked → Review & link") appears when unmatched refs exist.

Per-record sharing subsystem

A granular per-record sharing system layered on top of the legacy pf_visibility enum without removing it. Resolved by VisibilityResolver; the new model is additive (legacy fallback preserved unless Privacy mode is on).

Rule types (vr_rule_type)

  • private — explicit deny (only owner)
  • public — explicit allow (anyone)
  • users — payload {user_ids: [...]}; allow if viewer in list
  • cohort — payload {cohort_id: N}; allow if viewer in pcp_cohort_members for that cohort
  • link_token — payload {token: '...', uses_remaining: null|N}; allow if URL ?pcpshare=TOKEN matches
  • reciprocal — allow if viewer has a matching users rule sharing the same shape back to owner

Rules scope at three levels: (profile, namespace, key), (profile, namespace, NULL), or (profile, '*', NULL). Most-specific-first matching. Rules can have vr_expires (time-bounded) and vr_revoked (preserves audit trail).

Privacy mode

When Privacy mode is ON for a profile, a *-wide private rule is created. VisibilityResolver::canView() short-circuits to false instead of falling through to the legacy pf_visibility check, so only explicit share rules grant access. Default: OFF (back-compat).

Share dialog

Triggered by 🔗 chips on assessment reports, profile sections, life-story timeline. Modal with three tabs:

  • People: username autocomplete (↓/↑/Enter/Esc keyboard nav), per-shared-user pill with × to remove just that user, optional expires DatePicker, "Auto-share back" reciprocal toggle
  • Link: "Generate link" creates a link_token rule; copies the URL to clipboard with toast; optional max-uses + expires
  • Cohorts: dropdown of the owner's cohorts (managed at Special:MyCohorts); optional expires

Audit log

Every permitted view through a rule (not legacy) writes a row to pcp_visibility_view_log. Special:MyShareLog shows the last 200 views with timestamp, viewer (or anonymous IP masked to /24), namespace, key, rule id.

Choice / multi voting

The <vote> tag's binary up/down mode is unchanged. With type="single" or type="multi" + options="A; B; C" (2-5 entries, semicolon separator), it renders a compact chart-icon chip that expands inline to a radio (single) or checkbox (multi) picker with per-option count bars.

Server-side storage:

  • pcp_votable_elements.ve_options (JSON array of labels)
  • pcp_votable_elements.ve_options_h (first 8 hex of sha256; drift hash)
  • pcp_votable_elements.ve_results_policy (live / after-vote / hidden)
  • pcp_votes.v_choices (CSV indices)
  • pcp_votes.v_options_h (drift hash at vote time)

API route: same pharmacopediavote endpoint; presence of choices or options_h params routes to castChoice(). Response includes tally + user_choices (null for binary). Tally hidden per results policy.

Drift behavior: if the page editor changes the options list after votes exist, ve_options_h updates and new votes' v_options_h reflects the new value. Existing votes stay but their hash no longer matches (marked stale). New votes whose submitted hash mismatches the live one are rejected — protects against browser cache races. Tallies still aggregate by raw index, so RENAMING an option in place silently turns old votes into new-label votes; reordering is the dangerous case. Appending new options is safe.

Research ID

Every user profile carries a research_id: a 10-character hex string (bin2hex(random_bytes(5)) = 40 bits), generated once at profile create, stored UNIQUE in pcp_user_profiles.prof_research_id, and never reassigned.

Purpose: provides a stable opaque identifier for de-identified research participation. It does not reveal the user's wiki username, user_id, or HMAC voter_hash; it survives username changes; and it stays constant across the user's lifetime on the wiki. Users can find theirs in the Public identity fieldset on Special:MyProfile (single-click to select-and-copy).

Backfilled retroactively for all pre-existing profiles on 2026-05-18 (v0.9.4).

ClamAV scan rule (project standard)

Hard rule, set 2026-05-17: every server-accepted file upload (image, PDF, document, anything) MUST go through VirusScanner::scanFile($path) (includes/VirusScanner.php) BEFORE being moved to permanent storage. Fail-closed: if /usr/bin/clamdscan is unavailable or returns error, the upload is rejected.

Wired into:

  • LifeStoryStore::addImage() — life events / episodes / observations
  • LiteratureStore::storeUploadedPdf() — literature PDFs
  • ProviderAppStore::saveUploadedFile() — provider verification documents

AttachmentScanner (used by feature-request attachments) is left alone — its status-return model is intentional for the queued-moderation flow there. AntivirusHelper (the old silent-no-op variant) was deleted; all callers consolidated onto VirusScanner.

Autosave infrastructure

Every block on Special:MyProfile is wrapped in <div data-pcp-save-block="block-name">. The blocksave.js library:

  1. Listens for input and change events on every input inside any save-block
  2. 800 ms after the last event, POSTs the block's serialized form data to Special:SaveProfileBlock with block=block-name
  3. Shows a transient chip (top-right and bottom of the block): pending… → saving… → ✓ saved (fades after 1.2 s) or ✗ error (sticks, clickable to retry)
  4. Race-safe: if user keeps typing during an in-flight save, the in-flight save records what it sent; newer changes mark the block dirty again and schedule another save when the response returns
  5. Diagnosis + medicines "Add a row" slots are exempted from autosave (would create duplicates); they require an explicit + Add button
  6. Programmatic widgets (chip-pickers, units, smoking, alcohol, chronotype) fire change events on their hidden fields so the listener notices

Slider numbers are also clickable: a single delegated handler on every <output> next to a range slider swaps it for a number input on click, accepts a precise typed value (clamps to the slider's min/max), commits with Enter, cancels with Escape.

Scroll position is preserved across the rare reloads (delete operations on diagnoses / medicines / experience reports, and the auto-reload after a new diagnosis or medicine is added) via sessionStorage.

Interactions feature

The Interactions section is rendered by placing <pharmaInteractions/> anywhere in the wikitext of a med article (NS_MAIN) or a Category page (NS_CATEGORY).

Entity model

An interaction is an undirected edge between two endpoints. Each endpoint has a type (med or category) and a slug (DB-key form of the page title). Pairs are stored in canonical order: smaller (type, slug) tuple on the left.

Rendering rules

  • On a med page M, list:
    • Direct edges: rows where M is one side.
    • Transitive edges: rows where one side is a category C that M is itself a member of (via MW's categorylinks).
  • Direct wins: if the same counterparty is reachable both directly and transitively, drop the transitive duplicate.
  • On a Category page, list direct edges only (no transitive walk).
  • Sort: pooled valence_mean ascending (most negative on top). Nulls sink. Tiebreakers: n desc, then alphabetic.
  • Severe (any of pooled / user / provider vmean ≤ −83.0): red 4 px left border + red-tinted background + "severe" pill + counterparty title in red.

Add-interaction modal

Triggered by the + Add interaction button at the bottom of the section. Two-stage UX: search → click Use → confirm with Add interaction → POST to pharmacopediainteractionadd. Categories appear in the modal only if tagged with the marker category (default Category:MedCategory, configurable via $wgPharmacopediaInteractionCategoryMarker).

Experience reports

User-submitted reports of personal or clinical experience with a medicine, via <pharmaExperience/> on a med page. Stored pending in pcp_experience_reports; visible publicly only after sysop approval through Special:ReviewExperience.

Captured fields:

  • Perspective (personal / clinical)
  • Currently taking it (yes / no, stopped)
  • Duration (value + unit)
  • Dose (mg, decimal-precise)
  • Route (16-option dropdown: PO, IV, IM, SC, SL, buccal, inhaled, intranasal, topical, transdermal, PR, ophthalmic, otic, vaginal, insufflated, other)
  • Schedule (free text with datalist of QD / BID / TID / QID / q4h / q6h / q8h / q12h / qHS / qAM / qPM / PRN)
  • Patient count (clinical only): min + optional max for ranges
  • Efficacy (0–100 slider)
  • Side-effect burden (0–100 slider)
  • Stop reasons (personal + stopped only): JSON multi-select with optional severity slider per reason — codes: side_effects / ineffective / cost / no_longer_needed / clinician_advised / other
  • Free-text anecdote
  • Problems addressed (multi-pick with per-problem efficacy)
  • Effects experienced (multi-pick with per-effect valence + frequency)

Notable lessons learned

  • Synthetic Event needs bubbles:true to trigger delegated listeners. new Event('input') defaults to bubbles:false, so listeners on parent wrappers never see programmatic dispatches. Native input/change events bubble by default; only JS-fired ones don't. Pass { bubbles: true } explicitly. Bit DatePicker calendar-cell clicks 2026-05-18 — typing in the text field autosaved fine, but picking a date from the calendar didn't, because blocksave's wrapper listener never received the event.
  • MediaWiki form-field names collide with reserved URL params. A form <input name="title"> or name="action"> with user-controlled value silently HIJACKS MW's dispatch when POSTed (body param overrides URL param). Symptom: form submits but lands on a wiki article named whatever the user typed, with URL bar still showing the special page. Bit the episode form 2026-05-18 (user typed 'Fake one' as title → got a 404 'create article: Fake one' page). Fix: prefix ALL custom form inputs with pcp_ (both the input name="..." AND the matching $request->getVal('...', ...) read). Self-referential hidden inputs (name="title" value="<getPageTitle()>") are safe.
  • Cargo string fields cap at ~300 chars. structure and mechanism on MedTemplate are short VARCHARs; long prose goes in MEDIUMBLOB sections. Overruns silently lose Cargo data (MySQL Error 1406).
  • VARBINARY + LOWER() is a no-op. MariaDB's LOWER() returns binary types unchanged. pcp_diagnosis_abbreviations was migrated VARBINARY → VARCHAR/utf8mb4 so case-insensitive LIKE works natively without CONVERT() wrappers.
  • FlaggedRevs locks template inclusions by default. Config fix: $wgFlaggedRevsHandleIncludes=0 + remove NS_TEMPLATE from $wgFlaggedRevsNamespaces via an extension-function callback.
  • CSP must allow Cloudflare Turnstile and any other 3rd-party widget script source. Audit script-src / frame-src / connect-src / style-src whenever adding any 3rd-party JS widget.
  • Sidebar cache must be purged after CLI maintenance/edit.php writes to MediaWiki:Sidebar or other chrome pages.
  • CLI E_USER_DEPRECATED suppressed in LocalSettings.php (EmbedVideo / FlaggedRevs spam on MW 1.46). Web behavior unaffected.
  • MW ApiResult drops keys starting with _. Any field whose key starts with underscore in an ApiResult payload is treated as internal metadata and stripped. Rename to plain identifier. Bit Phase 2-4 of visibility-rules subsystem.
  • MW API serializes int-keyed assoc arrays unreliably. [23 => 'Alice'] may arrive as {"23": "Alice"} or worse. Always use list-of-objects ([{"id": 23, "name": "Alice"}]) for id-to-value maps across the API boundary.
  • PHP single-quoted strings don't interpret \xNN byte escapes. '\xF0\x9F\x94\x97' is 16 literal chars, NOT the 4-byte UTF-8 for 🔗. Use literal Unicode char or double-quoted \u{1F517}. Bit three times in one session.
  • PHP "0" is FALSY. !"0" evaluates to TRUE. So if ( !$x ) silently treats "0" (string zero) as missing. Bit choice-vote tallying when voter picked option index 0; vote was IN the DB but invisible to readers. Use === null || === for "missing or blank" intent. empty() has the same problem.
  • <span> can't contain <p>. MediaWiki auto-wraps tag content in <p> when there are newlines; browsers auto-close any <span> before the <p>, scattering child elements into wrong DOM positions. Use <div> for parser-tag wrappers whose content can span paragraphs (choice votes, life-story cards).
  • vis.Graph2d group style belongs at TOP LEVEL not nested in options. Nesting silently fails (no error, just invisible lines). Bit the trait-trajectory graph on first build.

Hooks

  • ParserFirstCallInit: register all parser tags
  • LoadExtensionSchemaUpdates: install / migrate schema (the sql/ directory + patches)
  • BeforePageDisplay: inject the ext.pharmacopedia.* ResourceLoader modules
  • UserGetRights + UserEffectiveGroups: verified-provider role wiring
  • Various special-page registrations via SpecialPage_initList

Configuration globals

  • $wgPharmacopediaInteractionCategoryMarker (default Category:MedCategory): only categories tagged with this marker appear in the add-interaction modal
  • $wgPharmacopediaVoteHashSecret (required): HMAC secret for v_voter_hash so vote rows can't be mapped back to user accounts by anyone reading the DB without the secret
  • (Various permission-grant arrays via standard MW $wgGroupPermissions)
