Changelog

Phase 0: Shared test infrastructure

• PrivStack.TestUtilities class library with GenericMockSdk (registration-based

entity routing), MockSdkExtensions (Seed, AssertStored, AssertActionSent),

and shared TestAppBuilder for Avalonia headless testing

• Living design doc (TESTING_STRATEGY.md) with full test plan across 4 phases

Phase 1: Pure logic tests (no SDK dependency)

• Calendar: RecurrenceGeneratorTests (49 tests) — daily/weekly/monthly/yearly

patterns, end conditions, excluded dates, exception events, DST, safety limits

• Calendar: IcsParserTests — RFC 5545 parsing, date formats, RRULE, export roundtrip
• Habits: StreakCalculatorTests (23 tests) — boolean/numeric/duration streaks,

frequency-aware gaps, completion rate, sparkline data, performance

• Email: HtmlSanitizerTests (44 tests) — element/attribute stripping, XSS vectors,

CID replacement, tracking pixels, media queries, constraint CSS

• Email: EmailThreadingServiceTests (12 tests) — MessageId chains, subject fallback,

circular reference protection, deduplication

• Notes: MarkdownBlockParserTests, BlockTreeHelperTests, LinkSearchScorerTests

(60 tests) — all 23 block types, tree traversal/mutation, fuzzy search scoring

• Contacts: VCardParserTests (20 tests) — vCard 2.1/3.0, QP encoding, types, bday
• Contacts: CsvContactParserTests (7 tests) — delimiter detection, header mapping
• Tasks: GitHubIssueFieldMapperTests (22 tests) — state/priority mapping, parsing
• Data: ContextDetectorTests + ProblemDetectorTests (19 tests) — SQL cursor context,

schema validation, ambiguous columns

• Journal: GpxParserTests (7 tests) — GPX 1.0/1.1, Haversine distance
• RSS: OpmlTests (7 tests) — OPML parse/export roundtrip

InternalsVisibleTo added to Contacts and Email plugins for test access.

Add three test files covering the core Notes plugin service classes:

• MarkdownBlockParserTests (24 tests): ATX/setext headings, paragraphs,

bullet/numbered/task lists, fenced code, blockquotes, horizontal rules,

images, footnotes, callouts, indents, tables, definition lists, mixed

content, and unique ID generation.

• BlockTreeHelperTests (14 tests): FindBlockById, GetBlockAtPath,

GetParentList, FlattenTree, IndentBlock, OutdentBlock, CollectBlockText

across nested block tree structures.

• LinkSearchScorerTests (12 tests): empty query, exact/prefix/fuzzy match,

case insensitivity, multi-word scoring, subtitle contribution, starts-with

bonus, and short-word fuzzy tolerance threshold.

Also adds InternalsVisibleTo attribute to Notes plugin csproj to expose

internal static classes (MarkdownBlockParser, LinkSearchScorer) to the

test project.

Bar chart:

• Dynamic height based on category count (32px per category, min 400px)
• Fix $0 data labels by hiding sub-$1 values
• Add XToolTipLabelFormatter for proper currency tooltips on hover
• Smart X-axis step intervals to prevent label cramming

Pie chart:

• Group categories below 10% of total into an "Other" slice
• "Other" slice rendered in distinct gray color with count/percentage tooltip
• Drill-down: click "View N smaller categories" to see Other breakdown
• Back button to return to main distribution view
• Increased chart height to 400px with centered horizontal alignment
• Section title updates dynamically based on drill-down state

Replace Version="*" with Version="$(PrivStackSdkVersion)" across all 15

plugin csproj files and the Finance test project. Add PrivStackSdkVersion

(1.68.0) to PrivStack-Plugins/Directory.Build.props.

This eliminates non-deterministic NuGet resolution in CI/standalone builds

where the wildcard would resolve to stale published versions (e.g. 1.5.3)

missing newer types like AdaptiveCartesianChart, causing MissingFieldException

at runtime. Local dev is unaffected — Directory.Build.props already swaps

these for project references when the sibling PrivStack-IO checkout exists.

OpenStreetMap tile server returns 403 for requests without a valid

User-Agent header. Mapsui's default CreateTileLayer() derives the

User-Agent from Assembly.GetEntryAssembly() which resolves incorrectly

in the plugin's AssemblyLoadContext, producing an empty/invalid value.

Pass an explicit "PrivStack/1.68" User-Agent to both the editor and

read-only map views.
