chore: release v1.20.1 (#437)

The shareStockStatus UI toggle was replaced by shareMedicationOverview in
commit e0fb77d, but the backend gating logic was left intact. Users who
had previously set shareStockStatus=false were stuck with empty stock
values ('-') on the shared medication overview with no UI to change it.

- Remove showStockStatus parameter from buildSharedMedicationOverview()
- Remove visibility gating that nullified stock fields
- Remove shareStockStatus from settings API responses and PUT schema
- Remove shareStockStatus from frontend types, hooks, and context
- Clean up all related test fixtures and dead test cases
- DB column share_stock_status retained (never remove columns)

+# Principal software engineer mode instructions
+
+You are in principal software engineer mode. Your task is to provide expert-level engineering guidance that balances craft excellence with pragmatic delivery as if you were Martin Fowler, renowned software engineer and thought leader in software design.
+
+## Core Engineering Principles
+
+You will provide guidance on:
+
+- **Engineering Fundamentals**: Gang of Four design patterns, SOLID principles, DRY, YAGNI, and KISS - applied pragmatically based on context
+- **Clean Code Practices**: Readable, maintainable code that tells a story and minimizes cognitive load
+- **Test Automation**: Comprehensive testing strategy including unit, integration, and end-to-end tests with clear test pyramid implementation
+- **Quality Attributes**: Balancing testability, maintainability, scalability, performance, security, and understandability
+- **Technical Leadership**: Clear feedback, improvement recommendations, and mentoring through code reviews
+
+## Implementation Focus
+
+- **Requirements Analysis**: Carefully review requirements, document assumptions explicitly, identify edge cases and assess risks
+- **Implementation Excellence**: Implement the best design that meets architectural requirements without over-engineering
+- **Pragmatic Craft**: Balance engineering excellence with delivery needs - good over perfect, but never compromising on fundamentals
+- **Forward Thinking**: Anticipate future needs, identify improvement opportunities, and proactively address technical debt
+
+## Technical Debt Management
+
+When technical debt is incurred or identified:
+
+- **MUST** offer to create GitHub Issues using the `create_issue` tool to track remediation
+- Clearly document consequences and remediation plans
+- Regularly recommend GitHub Issues for requirements gaps, quality issues, or design improvements
+- Assess long-term impact of untended technical debt
+
+## Deliverables
+
+- Clear, actionable feedback with specific improvement recommendations
+- Risk assessments with mitigation strategies
+- Edge case identification and testing strategies
+- Explicit documentation of assumptions and decisions
+- Technical debt remediation plans with GitHub Issue creation

 ## Critical Safety Rules
 
+- **Do EXACTLY what the user asks — nothing more.** If the user says "create a PR and merge to main", do only that. Do NOT also start a release. If the user says "do a release", do only the release. Never chain additional steps the user did not request.
 - **NEVER release, tag, push, or create PRs without explicit user confirmation at each step.** Always present your plan and wait for approval.
+- **This specialist agent is the only agent allowed to perform remote release operations after explicit confirmation.**
+- **Use GitHub MCP for all GitHub remote operations. Never use `gh` CLI.** Issues, PRs, workflow checks/logs, project updates, comments, merges, and releases must go through GitHub MCP tools only.
 - **NEVER push directly to `main`** — GitHub will reject it (`GH013: Repository rule violations`). All changes go through Pull Requests.
 - **NEVER skip CI checks.** Wait for all status checks to pass before merging.
 - **Testing ownership belongs to `@testing-manager`**. Do not plan or implement tests in this agent; request/hand off to testing-manager when testing work is required.
+- **Pre-PR local quality gate is mandatory**: before creating any PR, require confirmation from `@testing-manager` that lint is clean (no errors and no simple/fixable warnings) and all relevant tests passed locally.
+- **No CI-first failures policy**: do not use GitHub CI as first detection for obvious test/lint regressions; those must be reproducible and fixed locally before PR creation.
+- **Never trust a dirty local `main` workspace as release truth**: before splitting work, branching, or preparing a PR, fetch the authoritative remote and verify whether the local workspace is ahead/behind/stale relative to `<remote>/main`.
+- **If the main workspace is dirty, behind, or contains mixed stale copies of already-merged work, quarantine it**: do not branch from it and do not keep splitting PRs out of it. Create a fresh branch/worktree from the authoritative remote main and transplant only the intended scope.
 - **Track all work in the GitHub Project board.** Every PR should reference an issue. Move issues through the board as work progresses.
 - **ALWAYS verify Project board status after merge.** The `project-auto-done.yml` workflow moves items to "Done" automatically when issues close or PRs merge. Verify it ran successfully; if it didn't, move items manually via GraphQL (see Task 6).

+## GitHub Operations (GitHub MCP Only)
 
-- Never use `gh` commands that can open an interactive pager and block execution (requiring `q`).
+- Never use `gh` CLI in this agent.
-- Always run `gh` commands in non-interactive mode using `GH_PAGER=cat` (or `--no-pager` where supported).
+- Use GitHub MCP tools for all GitHub actions: issue creation/comments, PR creation/view/merge, workflow status/log inspection, project board updates, release publishing, and branch/PR metadata lookup.
-- Do not use these commands in agent flows:
+- Prefer structured MCP operations over shell-based GitHub access so remote actions stay explicit, auditable, and non-interactive.

+## Workspace Hygiene And Source-Of-Truth Rules
-- Use safe variants instead:
+
-   - `GH_PAGER=cat gh pr view <PR_NUMBER> --json statusCheckRollup --jq '<jq-filter>'`
+- The authoritative comparison target is the actual remote default branch used for shipping, normally `github/main` or `origin/main`. Determine it first and use the same remote consistently for fetch/diff/pull decisions.
-   - `GH_PAGER=cat gh api repos/<owner>/<repo>/commits/<sha>/check-runs --jq '<jq-filter>'`
+- Before any PR split or branch creation, run a source-of-truth audit:
+   1. fetch the authoritative remote
+   2. inspect `git status`
+   3. compare local `main` against `<remote>/main`
+   4. compare intended changes against `<remote>/main`, not only against local `HEAD`
+- If a dirty workspace contains files that are already present on `<remote>/main`, treat that workspace as stale local state, not as unshipped work.
+- When mixed local changes must be split into multiple PRs, do the classification first: `already upstream`, `intended for current PR`, or `unrelated/local-only`.
+- If the classification is unclear, stop using the dirty workspace as the source branch and move the intended scope into fresh worktrees from `<remote>/main`.
+- After a PR is merged, do not continue future PR extraction from an older dirty workspace unless it has been explicitly re-synced and re-audited against the authoritative remote.

+## Testing Strategy Defaults
+
+- **Default to targeted validation, not shotgun runs**: start with the smallest test command that exercises the changed behavior.
+- **Do not run every test by default**: broad full-suite runs are reserved for cross-cutting changes, shared infrastructure, release gates, or when focused runs show signal that wider breakage is plausible.
+- **Frontend browser behavior must use Playwright when the real browser matters**: routing, auth/session flows, focus behavior, form workflows, responsive behavior, optimistic UI rollbacks, and other end-to-end user journeys should be validated in Playwright instead of only Vitest.
+- **Frontend component logic that does not require a real browser stays in Vitest**: hooks, utilities, component state, rendering branches, and request handling should usually be validated with targeted Vitest tests first.
+- **Backend changes should usually prove three things separately**: affected Vitest regression scope, backend static gate (`tsc --noEmit` through `npm run check`), and broader backend suite only when the change touches shared route/service behavior.
+- **Escalate only when justified**: run full backend/frontend suites or broader Playwright coverage only if the touched area is shared, the failure mode is unclear, CI disproves the focused pass, or release-manager explicitly needs a broader pre-PR gate.
+
 ## Required Test Workflow
 
 1. Identify changed behavior and expected outcomes.
-2. Add/update tests near the affected feature.
+2. Map the change to the correct layer: backend Vitest, frontend Vitest, or frontend Playwright browser coverage.

+6. Run lint + required local test/build gates before PR handoff.
+7. Report what was run, what passed, and why broader suites were or were not needed.
+
+## Lint and Quality Gates
+
+- Run lint as part of every validation cycle when code changed.
+- Required before PR creation and before PR-ready handoff from `@release-manager`: no lint errors and no simple/fixable warnings left unresolved.
+- If lint fails, fix root causes first, then re-run affected tests.
+- Required before PR creation: relevant local tests must pass (`backend`/`frontend` unit tests and relevant Playwright scope when affected).
+- If CI fails after a claimed local pass, treat it as a test validity gap and close that gap with deterministic local reproduction.
+- Use `tsc` intentionally: backend and frontend type checks are part of the local gate and should be run through the existing `npm run check` scripts unless a narrower `tsc --noEmit` repro is needed during diagnosis.

 ## E2E Test Patterns
 
 - Use stable selectors and explicit assertions.
 - Avoid flaky timing assumptions; prefer waiting for concrete UI states.
 - For auth-sensitive flows, handle both auth-enabled and auth-disabled environments when applicable.
-- For CI triage, inspect failed run logs first, then reproduce locally with targeted specs.

+- Prefer user-meaningful assertions (visible state, persisted effects, API-visible outcomes) over brittle internal hooks.
+- Prefer the narrowest browser scenario that covers the changed user path before considering a full stable suite.
+
+## When To Run Broad Suites
+
+- Run the full backend Vitest suite when shared backend services, route helpers, schema-adjacent behavior, or broad scheduling logic changes can affect multiple route families.
+- Run the full frontend Vitest suite when shared context/providers, global hooks, router shells, or common rendering utilities change.
+- Run broader Playwright coverage when the change spans multiple user journeys, modifies auth/navigation foundations, changes network synchronization behavior, or a targeted browser test is insufficient to prove safety.
+- For small isolated fixes, a narrow Vitest file, a narrow Playwright spec, and the relevant `check` command are usually enough.

+## Test Validity Checklist

+- The test fails when the real target logic is intentionally broken.

+# MedAssist-ng - Copilot Entry Point
 
-## Purpose
+## VERY IMPORTANT
 
-Use `AGENTS.md` as the canonical governance source. Read the referenced skill files before starting any task.
+- Always keep agent work memory updated in `doku/memory_notes.md` so progress and decisions remain recoverable across context loss.
+- Always keep a user-facing work report updated in `doku/report.md` so completed work is easy to review.
+- This memory/report rule replaces the previous `doku/APP_BEHAVIOR.md` persistence requirement.
 
-## Project Orientation (Read First)
+Use `AGENTS.md` as the single source of truth for all governance, workflow, and skill rules.
 
-- **Product**: MedAssist-ng is a medication planner with stock tracking, reminders (email/push), refill history, and schedule sharing.
+## Required Startup Steps
-- **Tech stack**: React + TypeScript + Vite (`frontend/`), Fastify + TypeScript + Drizzle + SQLite (`backend/`).
-- **Request path**: Frontend uses `/api/*` only; backend route handlers live in `backend/src/routes/`.
-- **Primary backend modules**:
-	- Auth/SSO: `backend/src/routes/auth.ts`, `backend/src/routes/oidc.ts`, `backend/src/plugins/auth.ts`
-	- Medications/data: `backend/src/routes/medications.ts`, `backend/src/db/schema.ts`
-	- Reminders: `backend/src/services/reminder-scheduler.ts`, `backend/src/routes/planner.ts`, `backend/src/routes/settings.ts`
-- **Primary frontend modules**:
-	- Pages: `frontend/src/pages/`
-	- Shared app state: `frontend/src/context/AppContext.tsx`
-	- Domain hooks: `frontend/src/hooks/`
-	- Translations: `frontend/src/i18n/en.json`, `frontend/src/i18n/de.json`
 
-Use this orientation for quick navigation before applying the rules below.
+1. Read `AGENTS.md` first.
+2. Identify triggered skills from `AGENTS.md` and read each referenced `SKILL.md` before making changes.
+3. Follow delegation boundaries exactly (`@testing-manager` for testing, `@release-manager` for release orchestration).
 
-## Always-On Rules
+## Scope
 
-- English only for project artifacts.
+This file intentionally stays minimal to prevent duplicated or conflicting instructions.
-- **NEVER run remote git commands** — no `git push`, no `gh pr create/merge`, no `gh release`, no `git tag`. Prepare locally, then hand off to `@release-manager`.
-- Testing work belongs to `@testing-manager`.
-- PR/release/CI orchestration belongs to `@release-manager`.
-- Keep changes local, focused, and consistent with existing UI/API patterns.
-- **Hard PR scope + size rule**: one cohesive objective per PR; if scope drifts or diff becomes large (target <= 500 changed lines, hard split at ~800+), split into logical follow-up PRs instead of bundling.
-- Remove obsolete code when re-implementing — never leave dead code behind.
-- **Document behavioral discoveries**: When you discover or clarify how a feature works (e.g., what triggers notifications, how thresholds interact, which code paths exist), **always** add or update the relevant section in `doku/APP_BEHAVIOR.md`. This is mandatory — do not rely on conversation context alone.
-
-## MedAssist Essentials
-
-- Frontend calls backend through `/api/*`.
-- DB changes must stay backward-compatible (schema default + alter migration + null-safe reads).

+description: Apply assumption clarity, simplicity-first implementation, surgical diffs, and goal-driven verification for non-trivial coding tasks.
+---
+
+# Skill Instructions
+
+Use this skill as an execution style layer for implementation tasks where overengineering, broad refactors, or unclear assumptions are likely.
+
+## Use When
+
+- The request is ambiguous and assumptions must be made explicit.
+- The change can easily balloon in scope.
+- A bug fix or feature needs explicit success criteria and verification.
+- You need to keep diffs minimal and directly tied to the request.
+
+## Do Not Use When
+
+- The task is trivial and can be completed safely without extra process overhead.
+- The task is only about ownership routing (use `medassist-testing-handoff` / `medassist-release-handoff`).
+- The task is only about domain guardrails already covered by specialized skills (architecture, DB, i18n, UI, security, config, observability).
+
+## Core Principles
+
+### 1. Think Before Coding
+
+- Do not assume silently.
+- State assumptions explicitly.
+- If multiple interpretations exist, present them instead of picking one invisibly.
+- If uncertain or blocked by ambiguity, stop and ask.
+- If a simpler approach exists, call it out.
+
+### 2. Simplicity First
+
+- Implement the minimum code required to solve the asked problem.
+- Do not add speculative features, abstractions, or configurability.
+- Avoid defensive handling for impossible scenarios.
+- If the solution feels overcomplicated, simplify before finalizing.
+
+### 3. Surgical Changes
+
+- Touch only lines required for the request.
+- Do not refactor unrelated areas.
+- Match existing local style and patterns.
+- Remove only unused code introduced by your own change.
+- If unrelated dead code is discovered, mention it but do not remove it unless requested.
+
+### 4. Goal-Driven Execution
+
+- Translate requests into verifiable outcomes before implementation.
+- For multi-step tasks, define short steps with checks.
+- Verify the requested behavior explicitly before declaring done.
+
+Example execution frame:
+
+```text
+1. [Step] -> verify: [check]
+2. [Step] -> verify: [check]
+3. [Step] -> verify: [check]
+```
+
+## Response Format
+
+When this skill is used, report briefly:
+
+- Assumptions made (or clarifications requested)
+- Why the chosen approach is the simplest viable one
+- What was changed (and what was intentionally not changed)
+- Verification performed and result

@@ -26,6 +26,16 @@ Use `medassist-frontend-polish` only after these guardrails are satisfied.
 - Avoid custom inline modal/button patterns that diverge from project design.
 - Prefer extending existing CSS classes/styles instead of introducing parallel styling systems.
 
+### Modal requirements (non-negotiable)
+
+Every modal/overlay **must** follow these rules:
+
+1. **Escape key**: Call `useEscapeKey(active, onClose)` from `hooks/useEscapeKey`. This registers a document-level `keydown` listener that works regardless of focus. **Never** rely on `onKeyDown` on an overlay div — it only fires when the overlay has focus, which almost never happens.
+2. **Scroll lock**: Call `useScrollLock(active)` from `hooks/useScrollLock` if the modal is **not** already covered by App.tsx's centralized `useScrollLock` call. Page-local modals (e.g. `ReportModal`, `ExportModal`) must call it themselves.
+3. **Click-outside close**: The overlay div gets `onClick={onClose}`, and `.modal-content` gets `onClick={(e) => e.stopPropagation()}`.
+4. **Key event containment**: `.modal-content` gets `onKeyDown={(e) => { if (e.key !== "Escape") e.stopPropagation(); }}` — this prevents non-Escape keys from leaking out while still allowing Escape to propagate to the document-level handler.
+5. **Nested sub-modals** (e.g. edit-stock inside MedDetailModal): Use `useEscapeKey` with `{ capture: true }` so the innermost modal intercepts Escape before the parent's handler fires.
+
 ## Decision Heuristics
 
 1. If an equivalent component exists, reuse it.

-# GitHub Project Setup
-
-This repository includes a GitHub Actions workflow that automatically adds new issues to a GitHub Project for tracking feature requests and bugs.
-
-## Setup Steps
-
-### 1. Create a GitHub Project
-
-1. Go to your GitHub profile → **Projects** → **New project**
-2. Choose the **Board** template (recommended for feature tracking)
-3. Name it e.g. **MedAssist-ng Roadmap**
-4. Configure the default columns:
-   - **Triage** – New issues land here
-   - **Backlog** – Accepted but not yet started
-   - **In Progress** – Currently being worked on
-   - **Done** – Completed
-
-### 2. Create a Personal Access Token (PAT)
-
-The workflow needs a token with project permissions. The built-in `GITHUB_TOKEN` does not support GitHub Projects.
-
-1. Go to **Settings** → **Developer settings** → **Personal access tokens** → **Fine-grained tokens**
-2. Click **Generate new token**
-3. Set:
-   - **Token name**: `add-to-project`
-   - **Expiration**: Choose an appropriate duration
-   - **Repository access**: Select **Only select repositories** → `DanielVolz/medassist-ng`
-   - **Permissions**:
-     - Repository permissions: **Issues** → Read
-     - Organization permissions (if applicable): **Projects** → Read and write
-   - For **user-owned projects**, you need a **classic** token with the `project` scope instead
-4. Copy the generated token
-
-### 3. Add Repository Secrets and Variables
-
-1. Go to the repository → **Settings** → **Secrets and variables** → **Actions**
-2. Add a **secret**:
-   - Name: `ADD_TO_PROJECT_PAT`
-   - Value: The PAT from step 2
-3. Add a **variable** (under the **Variables** tab):
-   - Name: `PROJECT_URL`
-   - Value: The full URL of your GitHub Project (e.g. `https://github.com/users/DanielVolz/projects/1`)
-
-### 4. Verify
-
-1. Create a test issue using the **✨ Feature Request** template
-2. Check the **Actions** tab to see the workflow run
-3. Verify the issue appears in your GitHub Project under **Triage**
-
-## How It Works
-
-The workflow (`.github/workflows/add-to-project.yml`) triggers when:
-- A new issue is **opened**
-- A label is **added** to an existing issue
-
-Issues with any of these labels are automatically added to the project:
-- `enhancement` – Feature requests
-- `bug` – Bug reports
-- `triage` – New issues needing review
-
-Both the feature request and bug report issue templates automatically apply the `triage` label, so all new issues from templates are captured.
-
-## Customization
-
-### Adding more labels
-
-Edit `.github/workflows/add-to-project.yml` and add labels to the `labeled` field:
-
-```yaml
-labeled: enhancement, bug, triage, documentation
-```
-
-### Restricting to feature requests only
-
-Change the `labeled` field to only include `enhancement`:
-
-```yaml
-labeled: enhancement
-label-operator: OR
-```
