Who Need Help — implementation verification

Observed on 2026-07-18 in the local workspace. This report separates observed results from product limits and unknown production properties.

Verified MVP capabilities

Requirement	Status	Observed evidence	Limit
Urgent medicine-help flow	Implemented and tested	Request creation, discovery, matching, start, handover, two-party completion, and review rules are covered by the Phoenix test suite and exercised in the local UI.	The product coordinates pickup of an already purchased or reserved legal item; it is not a pharmacy, medical, or emergency service.
Urgent roadside help	Implemented and tested	Fuel, car wheel, bicycle, motorcycle, vehicle-breakdown, and secured-incident categories are seeded as a translated hierarchy. Server and LiveView tests exercise category paths, required fields, allowed values, boolean normalization, unknown-field rejection, and request creation.	Roadside requests require no immediate danger; this is not emergency response or professional recovery.
Extensible categories	Implemented and tested	Categories and validated text/select/boolean fields are stored in PostgreSQL. Proposal, vote, approve, reject, and merge paths have automated tests.	Coffee, cinema, hiking, and other social activities remain separate from urgent-help safety and ranking rules.
Separate Activity mode	Implemented and tested	Coffee, cinema, walk, and hiking categories use a separate activity lifecycle. Domain and two-client LiveView tests cover creation, join request, organizer approval, capacity enforcement, public/pending/chat privacy, exact-location disclosure to approved users, group chat, blocking, completion, and zero impact on helper reputation. Activity and message reports expose only the linked group conversation to an audited moderator; moderators can hide and restore reported activities.	This does not guarantee participant identity or physical safety.
Map and discovery	Implemented and browser-verified	A headed Chrome session rendered the MapLibre request map, marker, controls, attribution, and configured OpenStreetMap raster tiles. Tile requests returned HTTP 200 during the check.	A production operator must configure a tile provider appropriate for its policy and traffic.
Private matched chat	Implemented and cross-client verified	A message sent from the helper browser appeared in the requester's browser without reload. An earlier Android emulator run also sent a message that appeared in the requester browser in real time.	There is no unsolicited general-purpose inbox.
Consent-driven live tracking	Implemented and cross-client verified	On API 37, Android started `TrackingService` as a location foreground service with a persistent Stop notification. After Home minimized the Activity, an emulator coordinate change reached PostGIS. Notification Stop removed the service, notification, active session, and raw position.	Browsers stop with the page. Android has no `ACCESS_BACKGROUND_LOCATION`, unattended start, or route history.
Privacy settings	Implemented and browser-verified	The profile exposed hidden, approximate public, exact for active match, and explicit exact-public options. Blocking and current-position cleanup have automated tests.	Exact public location remains a user opt-in; legal privacy and retention text still requires jurisdiction-specific review before launch.
Reputation and anti-abuse	Implemented at MVP level	Handover codes, two-party completion, double-blind reviews, unique-counterpart ranking, optional movement/proximity evidence, reports, blocks, abuse signals, and moderator audit paths have automated tests.	The system is not bot-proof and does not claim identity verification. No punitive numeric policy is enabled without measured and approved thresholds.
Social profiles	Manual links implemented; GitHub verification implemented and automated-tested	Manual links cannot set verification fields. The optional GitHub flow uses state, PKCE, a user-bound one-time session, unique provider ownership, and an audit record; 146 tests pass, including callback replay/state checks. No access-token field exists and the controller receives only normalized identity attributes.	The staging operator has not supplied GitHub OAuth credentials, so the real external provider redirect/callback remains disabled and has not been browser-verified. Other providers remain manual/unverified.
Voluntary thanks	Implemented as an external optional link	A helper can expose an optional link after completion; the UI states that the platform does not process the payment.	The platform does not provide payments, escrow, refunds, tax reporting, or payment guarantees.
Android client	Debug client implemented and emulator-verified	The native package `org.whoneedhelp.mobile.debug` launches the same authenticated LiveView app. Login, map, chat, permission prompts, minimized foreground-service location updates, notification Stop, and server cleanup were exercised on API 37.	Production signing, a public production origin, Play Store publication, unattended/background-permission tracking, and iOS are not implemented.
Multiple web/worker instances	Implemented and locally verified	Docker Compose and kind each ran 2 web and 2 worker replicas. The project probes cross-node Phoenix PubSub using different BEAM nodes. Kubernetes web/worker pods were Ready with zero restarts at the final observation.	Local PostGIS is a single instance. Production database HA, backups, and recovery are operator work and are not claimed complete.

Reproducible checks

./scripts/test.sh: 146 tests, 0 failures after verified GitHub linking on Elixir 1.20.2 and Erlang/OTP 29.0.3.
mix compile --force --warnings-as-errors and mix format --check-formatted: passed after the OAuth change.
The generated Activity migration was rolled back by exactly one step and migrated forward again against who_need_help_test; both directions passed.
The Activity-report migration was also rolled back and migrated forward. The observed database constraint changed from exactly one of 3 urgent-help targets to exactly one of 5 urgent-help/Activity targets.
mix format --check-formatted: passed in the final run.
Android Docker build target: testDebugUnitTest, lintDebug, and assembleDebug passed; the final lint report contains no errors or warnings.
Release Android guard: a release build without WNH_BASE_URL failed as intended; release configuration accepts only an explicit HTTPS origin.
Helm lint, template rendering, server-side dry-run, rollout waits, readiness checks, and cross-node PubSub verification passed in the local kind cluster.
Browser verification used headed Chrome. The authenticated matched-request page rendered its chat, MapLibre marker, and live-location controls with no console errors or warnings after the foreground-service rollout.

Android artifact:

android/dist/who-need-help-debug.apk
Final post-upgrade SHA-256: 063f3d8d877009ee229a403692e4b16517244dd9e7dddab4c2b3c202c5def4b8
Observed manifest values: version 0.1.0-debug, minimum SDK 24, target and compile SDK 37.

Configuration finding

WNH_DEBUG_BASE_URL is a required Android build input, because the trusted same-origin value is compiled into the debug APK. Its concrete local value is read from the repository's ignored .env by scripts/android-build.sh and is passed to Docker with --build-arg. android/Dockerfile only declares ARG WNH_DEBUG_BASE_URL; it contains no URL default.

The example http://10.0.2.2:4010 remains only as unit-test data for origin matching. It is not a runtime or build default. The ignored .env is also excluded from the root Docker build context.

Database observations

The post-roadside local Compose observation found 2 users, 1 help request, 7 messages, and 1 assignment before and after deployment. Category seeding changed only the category count from 1 to 9: 7 selectable categories and 2 inactive grouping nodes. These are local scenario data; the database is not assumed empty.

The Activity migration then preserved those same user/help/message/assignment counts, added empty activities, activity_participants, and activity_messages tables, and expanded the category tree to 14 rows: 9 help rows and 5 Activity rows. A validated custom-format dump was created immediately before that migration at output/backups/compose-before-activity-20260718-203930.dump; this ignored local artifact is not a substitute for the still-required isolated restore drill.

The final kind observation found 0 users, 0 help requests, and 0 messages. That state was queried before changing the database workload. The migration from the old emptyDir Deployment created a custom-format dump, validated it with pg_restore --list, changed PostGIS to a persistent StatefulSet, and restored the dump before the Helm upgrade. The final kind database reported PostgreSQL 18.4 and PostGIS 3.6.4.

The local kind Secret contains independently generated values. Only their decoded lengths were inspected: the PostgreSQL password is 64 characters and each application secret is 128 characters. Secret values were not printed or written to tracked files.

Dependency-upgrade observations

The running Compose and kind releases reported Elixir 1.20.2 and Erlang/OTP 29.
Compose reported Traefik 3.7.8 and Mailpit 1.30.4; Compose and kind both reported PostgreSQL 18.4 and PostGIS 3.6.4.
The production asset build reported Tailwind CSS 4.3.3 and daisyUI 5.6.18; esbuild is configured at 0.28.1.
The isolated Node build stage reported Node.js 24.18.0, npm 12.0.1, npm outdated --json returned {}, and npm ci reported zero known vulnerabilities.
The Android build used Android Gradle Plugin 9.3.0, Gradle 9.6.1, Command-line Tools 22.0, and its embedded Android CLI 1.0.15857036. Unit tests, lint, and debug assembly passed; the lint report says “No errors or warnings.” The rebuilt emulator image contains the API 37 ps16k AVD and APK, and its emulator 36.6.11.0 binary returned its version successfully at runtime.
The final complete scripts/kind-up.sh run was idempotent and finished with both 2-replica Deployments Ready and a successful cross-replica PubSub probe.

The migration 20260718114233 and reverse block lookup index blocks_blocked_id_blocker_id_index were present. An actual EXPLAIN ANALYZE for that reverse lookup selected the index. The table contained no block rows, so this confirms query shape, not production performance.

Exact production capacity, minimum CPU/RAM, and scaling thresholds are unknown: there is no representative load dataset or target-environment measurement. The Helm chart therefore does not invent resource limits or an HPA policy.

Public staging observation

On 2026-07-18, whoneedhelp.imalto.site was published through the existing Ubuntu Nginx gateway and its OpenVPN path to the local Compose proxy. HTTP redirected to HTTPS; the homepage, fingerprinted assets, and both health endpoints returned HTTP 200. A headed Chrome session rendered the public page with zero console errors or warnings. A complete WebSocket Upgrade request to /live/websocket returned 101 Switching Protocols.

The observed Let's Encrypt certificate had the correct DNS:whoneedhelp.imalto.site SAN and an expiry of 2026-10-16. Nginx and the Certbot renewal timer were active. This verifies the current staging path; it does not make the workstation or gateway a production availability environment.

After the Activity rollout, headed Chrome rendered the updated public navigation, followed the Activity link to the authenticated route, and received the expected login redirect and flash with zero console errors or warnings.

After commit 307794c, staging was rebuilt with the optional GitHub OAuth boundary. Both web and both worker replicas started, the cross-node PubSub probe passed, public home/readiness returned HTTP 200, and the before/after database counts remained 2 users / 1 request / 7 messages / 14 categories / 1 assignment / 0 activities / 0 reports / 0 social identities.

A headed Chrome E2E run then registered a uniquely named example.invalid account, consumed its confirmation link from local Mailpit, authenticated, opened /profile, and observed:

the GitHub network option and the explicit provider-disabled explanation;
no Verify button while both OAuth environment variables were absent;
a manually added Telegram link labelled unverified;
removal of that owner-controlled manual link;
a direct /auth/social/github request returning to the profile with the controlled provider is not configured flash;
zero browser console errors or warnings.

The exact E2E user was checked for every foreign-key relationship to users. It had only its one authentication token and no domain records after the manual link was removed. That exact user was then deleted through Ecto, its browser session became invalid, the generated Mailpit message was deleted individually, and the original database counts were observed again. The browser windows were left open.

Known work before a public production launch

Replace the temporary staging origin with the production-owned domain and production-sign the Android app.
Operate PostgreSQL/PostGIS with backups, recovery testing, and the required availability model.
Load-test representative data and traffic, then set measured pool, resource, autoscaling, and action-limit policies.
Add pagination or bounded loading where real measurements show that request, chat, moderation, or leaderboard result sets require it.
Publish jurisdiction-specific emergency contacts, privacy, retention, prohibited-items, and voluntary-payment guidance after legal review.
Create and configure a GitHub OAuth App, then exercise the real external provider redirect/callback in a headed browser. Until then staging keeps the provider disabled and manual links remain unverified.
