From 23a9b2e805551b39aeb6a206dd0cb983b75bc677 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 27 Mar 2026 10:51:20 +0000 Subject: [PATCH 1/5] Implement browser storage for user annotations (#159) Add automatic save/restore of annotations (analysis markers, harmonic sets, doppler curves) using the Web Storage API. Trainer pages (identified by an "ANALYSIS" link) use localStorage for permanent persistence; student pages use sessionStorage for session-scoped persistence. - New storage adapter module (src/core/storage.js) with context detection, key generation, save/load/clear, schema versioning, and graceful degradation - JSDoc types for StoredAnnotations and related entities - GramFrame constructor integration: restore on init, save on state change - "Clear gram" button on trainer pages to reset all annotations - Comprehensive Playwright tests covering all 3 user stories plus edge cases - All 101 tests pass, typecheck clean, build clean https://claude.ai/code/session_01Gb6npXwykVzbvHBZUgmYty --- specs/155-browser-storage/tasks.md | 64 ++--- src/core/storage.js | 175 +++++++++++++ src/gramframe.css | 37 +++ src/main.js | 147 ++++++++++- src/types.js | 49 ++++ tests/fixtures/student-page.html | 32 +++ tests/fixtures/trainer-page.html | 33 +++ tests/helpers/gram-frame-page.js | 66 +++++ tests/storage.spec.js | 407 +++++++++++++++++++++++++++++ 9 files changed, 975 insertions(+), 35 deletions(-) create mode 100644 src/core/storage.js create mode 100644 tests/fixtures/student-page.html create mode 100644 tests/fixtures/trainer-page.html create mode 100644 tests/storage.spec.js diff --git a/specs/155-browser-storage/tasks.md b/specs/155-browser-storage/tasks.md index 3396f12..aa3ec9b 100644 --- a/specs/155-browser-storage/tasks.md +++ b/specs/155-browser-storage/tasks.md @@ -19,8 +19,8 @@ **Purpose**: No new project initialisation needed — GramFrame is an existing project.
