Add CSV import/export feature with Formatting module - #79
Conversation
Start the CSV import/export spec project: the project overview capturing the requested columns, import flow (batch ID, warnings/errors, two-phase scan-then-import), export flow, and the Settings section. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019uJ5vvSZQeALLcULAatrfX
Covers the CSV contract (columns, aliases, dates, escaping), the scan-then-commit import flow with its error/warning taxonomy, the shared bracketed transcript format used by export, Copy and import parsing, the async export flow, the Settings section, and the user-facing guide. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019uJ5vvSZQeALLcULAatrfX
Architecture: a Foundation-only Formatting module (TimeFormatting moved down from DesignSystem, plus ISO-8601 and the shared "[0:23] Steve" transcript render/parse), an ImportExport module (RFC 4180 parser, pure scanner, chunk-streaming exporter), DataStore fields and APIs, and the Settings wiring. Also folds in two spec changes: misformatted rows are now a skip-with- warning rather than a file-level critical error, and a debug-build "Delete Imported Meetings" affordance.

Overview, functional spec, architecture, and implementation plan are all approved. Transcript rendering collapses consecutive same-speaker segments, as specified. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019uJ5vvSZQeALLcULAatrfX
… and future CSV import/export (csv_import_export Phase 1) New Foundation-only `Formatting` module in BiscottiKit: - `TimeFormatting` moved verbatim from `DesignSystem` (which now depends on `Formatting`); seven consumer targets and four test targets rewired. - `ISO8601Formatting`: renders `2026-01-03T14:26:42.017Z` via a per-call `ISO8601DateFormatter` (the `Date.ISO8601FormatStyle` first sketched truncates sub-millisecond error downward, so it was rejected — recorded in architecture §3.2); lenient parse accepts fractional/second-precision ISO-8601, bare epoch seconds/milliseconds split at 1e11, and bare yyyy-MM-dd at local midnight, all whole-string matched. - `TranscriptTextFormatting`: the single "[0:23] Name" transcript text format — `displayName`, `render` (same-speaker collapse, blank-line separated turns), and `parse` (header regex with inline "Name: text" shape, one segment per line, sequential speaker IDs, Unknown Speaker at 0 before any header). `TranscriptSegmentDraft` added to DataStore as parse's output type. Call sites rewired onto the shared renderer; duplicates deleted: `TranscriptContent.plainText`/`displayName` (Copy button now emits the bracketed form) and `MCPServer`'s private `TranscriptTextFormatter` (MCP transcript timestamps change `[00:04]` -> `[0:04]`; tests updated and `mcp_real_client` marked not-run per the staleness rule). New `FormattingTests` target: moved `TimeFormattingTests` plus ISO-8601 render/parse/boundary cases and transcript render/parse/round-trip suites. Phase 1 of the csv_import_export spec project is complete; functional spec §4 and architecture §3.2 amended to match the shipped collapse and formatter decisions.
…raft types, write/read/delete paths (csv_import_export Phase 2)
…unk-streaming exporter (csv_import_export Phase 3)
AppCore gains the three import/export actions (scan off-main, batch commit + reload, CSV export) plus the debug-only imported-counts and bulk-delete pair. Settings gains an Import/Export section after Custom Vocabulary: two rows with Learn-more links to the new user guide (App/ImportingExporting.md), per-button spinners, open/save panels behind injectable seams, and the full alert flow (blocked / review with Cancel-default / result / failure). A header-only CSV commits zero meetings deliberately and reports "Imported 0 meetings." Debug builds gain a Delete Imported Meetings row with the destructive-confirmation flow; replacing an existing export preserves the old file on failure (replaceItemAt). Exports over an existing destination replace safely.
…ild) Critical: the export replace-check decoded the save path (path(percentEncoded: false)), which silently lost confirmed exports at paths with spaces; a hostile Int.min epoch value no longer traps the import scan. Moderate: the exporter writes via Data().write and propagates real errors (CSVExportError deleted); .nothingToImport gates on real data rows so trailing blank lines keep header-only files on the commit-zero path; blocked alerts now also list the warning counts (spec §3.3 touched up); exportData dedupes duplicate IDs and the write path skips taken meeting IDs; exportData reuses mapTranscript (now internal); dismissImportAlert drops a held scan; AppCore.exportMeetingsCSV takes a directory so tests stop sleeping past second boundaries (.serialized kept only on the export suite). Mild: whitespace-only lines, dead code and dead API removed, save panel restricts to .csv and opens in Downloads, spinner no longer covers the file chooser, CSVParser exact rowPending flag and index iteration, exporter close-failure surfaced. Adds message-copy, failure-path, store read-path, and path-with-space tests; updates the stale MCP transcript-format spec and the user guide.

Qualify the “no meetings” blocking error.
The guide says that an import is blocked when it “contains no meetings that can be imported.” This also describes a valid header-only CSV. MeetingCSVImporter.scan keeps header-only files error-free, and AppCoreImportExportTests.commitHeaderOnly commits zero meetings without writing to the store. Require at least one data row before reporting this blocking error.

According to Apple’s current SwiftData ModelContext documentation, does a failed save discard pending inserts, or must the caller invoke rollback()?
💡 Result:
According to Apple's SwiftData documentation, a failed call to save does not automatically discard pending inserts or other uncommitted changes in a ModelContext [1][2][3]. The save method is responsible for writing pending inserts, changes, and deletes to persistent storage [1][3]. If this operation fails (throws an error), the changes remain in the context's memory. To discard these pending changes and revert the models to their most recent committed state, you must explicitly invoke the rollback method [2][3][4]. The rollback method is specifically designed to discard pending inserts and deletes, restore changed models to their most recent committed state, and empty the undo stack [1][4]. Therefore, if you need to ensure the context is clean following a failed save, you should handle the error and call rollback [2][3].

Rollback pending changes when the import save fails.
insertImportedMeetings inserts the meeting and transcript graph into DataStore.context, then calls DataStore.save(). SwiftData retains pending changes after a failed save. Call context.rollback() before rethrowing; otherwise, a later save can persist an import reported as failed.

Preserve colons in speaker names.
parseHeader treats every colon after the timestamp as the inline-text delimiter. A rendered speaker name such as Research: Platform imports as speaker Research plus content Platform. The resulting drafts are persisted, so this corrupts the speaker mapping and transcript content during export/import round trips.
Escape speaker names in render and decode them here, or define an unambiguous inline-text grammar.

CSV injection spreadsheet CSV leading = + - @ formula interpretation official documentation
💡 Result:
CSV injection, often referred to as Formula Injection, occurs when spreadsheet software (such as Microsoft Excel or LibreOffice Calc) automatically interprets data in a CSV file as an executable formula if the cell content begins with specific trigger characters [1][2][3]. Spreadsheet software typically interprets a cell as a formula if its first non-whitespace character is one of the following [1][2]: = (Equals) + (Plus) - (Minus) @ (At) Additionally, tab (0x09), carriage return (0x0D), and line feed (0x0A) characters are often stripped or handled by the software, meaning fields beginning with whitespace followed by a trigger character can also be evaluated as formulas [1][2]. In certain locales, full-width (double-byte) variants of these characters (e.g., ＝, ＋, －, ＠) may also trigger formula interpretation [1][4]. Mitigation strategies often involve sanitizing data before it is written to the CSV file to ensure it is treated as literal text. Common approaches include: 1. Prepending a single quote (') to the field value [5][6]. 2. Prefixing the content with a tab character (0x09) inside a quoted field (e.g., "\t=1+1") [1][7]. 3. Ensuring no cell starts with the aforementioned trigger characters by validating or encoding user-controlled input at the export layer [4][3]. There is no universal, perfect mitigation because different spreadsheet applications handle CSV files differently, and Microsoft Excel, in particular, may remove quotes or escape characters when a file is saved and subsequently reopened, potentially re-activating previously neutralized formulas [1][5][7]. Consequently, experts recommend a defense-in-depth approach, treating spreadsheet-level warnings as a secondary control and focusing on robust input sanitization at the export site [2][7].

Align the row-error rule with the functional specification.
This line makes invalid values in any row a critical error. functional_spec.md §3.2 defines those rows as warnings that are skipped while valid rows import. Update this overview so future work does not change the import flow to all-or-nothing.

In `@specs/projects/csv_import_export/project_overview.md` at line 25, Update the
CSV import error rule in the project overview to distinguish missing required
fields from invalid values in individual rows: invalid rows should produce
warnings, be skipped, and allow valid rows to import, as specified in
functional_spec.md §3.2. Keep critical-error handling for missing required CSV
fields or other cases explicitly defined as critical.

Summary
Implements CSV import/export functionality for meetings, completing the
csv_import_exportspec project. Introduces a newFormattingmodule (Foundation-only, shared formatters), theImportExportmodule (RFC 4180 CSV parser/writer + importer/exporter), storage layer additions toDataStore, and wires everything intoSettingsUIandAppCore.Key Changes
New modules:
Formatting— Foundation-only module with three shared formatters:TimeFormatting(moved fromDesignSystem)ISO8601Formatting(CSV date render + lenient parse)TranscriptTextFormatting(render + parse the[M:SS] Nameformat)ImportExport— CSV import/export engine (no UI, no AppKit):CSVParser/CSVWriter— RFC 4180 with lenient parsing (mixed line endings, BOM stripping, ragged rows)MeetingCSVImporter.scan()— pure, store-free scan producingImportScanResultwith drafts, warnings, and critical errorsMeetingCSVExporter— chunk-streaming export to temp file (bounded memory regardless of library size)ImportScanResult/ImportWarning/ImportCriticalError— error/warning taxonomy from functional spec §3DataStore changes:
