Session Handoff

Current Objective

• Goal: Work through open issues one at a time, all consolidated into a single PR (user explicitly asked for fewer PRs, not one per issue).
• Current status: 6 issues done and pushed (#33, #36, #31, #39, plus #40/#41/#42/#48 from an earlier session), all on one branch/PR. Issue #38 (i18n) was scoped but paused before any code was written — waiting on the user's answer to a scope question.
• Branch / commit: claude/fix-directory-symlink-pull-260713 @ 4eebebc → PR #51 (open, all CI checks green as of last check)

Completed This Session

• #31 - fix: surface a clear error when requestUrl() itself rejects with HTML content — some Obsidian versions eagerly JSON-parse inside requestUrl(), so a login/proxy HTML page rejected the whole call with a raw SyntaxError, bypassing the existing parseJson() HTML-detection wrapper. Added the same detection to safeRequest's outer catch.
• #33 - fix: symlinked directories no longer break pull discovery — a directory symlink is a single git blob, not a real tree; local scanning recursed into it as if it were, causing bogus remote .gitignore 404s and a permanently-stuck "remote only" status. Also fixed createLocalSymlink's missing Windows symlinkSync type hint.
• #36 - perf(refresh): use tree blob SHAs to avoid per-file content fetches — refresh now compares a locally-computed git blob SHA against each tree entry's SHA instead of one getFile network call per file; diff content is fetched on demand via a new getBlob(sha, path) per service. Symlink-aware hashing (real/follow/skip modes) per the issue's follow-up design.
• #39 - feat: show new feature tips after update — new src/changelog.ts (hand-curated, separate from the auto-generated CHANGELOG.md) with a notable flag per entry, a WhatsNewModal, and a lastSeenVersion setting so the tip shows once per upgrade only.
• Consolidated everything (this session's 4 issues + the prior session's #40/#41/#42/#48) onto one branch/PR (#51) per the user's explicit request to reduce PR count — closed/merged the now-redundant PRs #49/#50/#52/#53.
• #38 (i18n) - paused, not started. Counted scope (~47 strings in settings.ts, ~24 in SyncStatusView.ts, 37 Notice() call sites across 4 files) and asked the user how deep to scope it; the question prompt was dismissed without an answer before they ran /firstsun-harness. No src/i18n/* files exist yet — don't assume a design, ask again first.

Verification Evidence

Check	Command	Result	Notes
Lint	npx eslint .	0 errors	Repo-wide, no exceptions
Type check + compat	npm run build	Pass	Includes typecheck-compat.mjs against Obsidian 1.11.0
Tests	npx vitest run	302/302 passed	22 test files
Duplication	npx jscpd --min-lines 5 --min-tokens 50 src	14 clones, all pre-existing	Checked after every commit — SonarCloud's gate is 3% on new code, learned this the hard way earlier (PR #49 failed at 8.3%)
Manual (in Obsidian)	—	Not done	No Obsidian instance available in this environment

Files Changed (this session, cumulative across the 4 issues)

• src/services/git-service-base.ts, git-service-interface.ts, github-service.ts, gitlab-service.ts, gitea-service.ts — tree-entry sha, getBlob(), HTML-error detection in safeRequest
• src/logic/gitignore-manager.ts, src/ui/SyncStatusView.ts — symlink-directory recursion guard, SHA-based status refresh, lazy diff loading
• src/utils/symlink.ts — Windows symlinkSync type hint
• src/utils/git-blob-sha.ts, src/utils/version.ts (new) — SHA-1 blob hashing, numeric version compare
• src/changelog.ts, src/ui/WhatsNewModal.ts (new) — what's-new modal + data
• src/ui/components/DiffPanel.ts, FileListItem.ts — on-demand diff fetch
• src/settings.ts, src/main.ts — lastSeenVersion field, update-check wiring
• Corresponding test files under tests/ for all of the above (302 tests total)

Decisions Made

• One PR, not one-per-issue: user said "不要那麼多pr merge" (don't want so many PRs). All further issue work goes directly onto claude/fix-directory-symlink-pull-260713 — do not create a new branch/PR for the next issue.
• src/changelog.ts is hand-curated, separate from CHANGELOG.md: the auto-generated changelog (via semantic-release) isn't shipped in release assets and is too commit-log-granular for an end-user popup anyway.
• Deduped two accidental code-duplication regressions mid-session (test mocks, getBlob bodies) before they could trip SonarCloud's new-code gate again.

Blockers / Risks

• #38 (i18n) needs a scope answer from the user before any code is written. Options put to them: (a) build the i18n mechanism + fully migrate settings.ts only, Notices later; (b) fully migrate settings.ts and all 37 Notice call sites now; (c) build just the t()/detection/fallback mechanism with a couple of sample keys, defer actual string migration. Don't guess — the wrong choice means redoing a large diff.
• PR #51 is now fairly large (6 issues). Consider flagging to the user that it may be worth reviewing/merging before more commits pile on.

Next Session Startup

1. Read CLAUDE.md, feature_list.json, progress.md, then this file.
2. Run ./init.sh before editing.
3. Ask the user for #38's scope decision (see "Blockers / Risks") before touching any i18n code.
4. All new commits go on claude/fix-directory-symlink-pull-260713 (PR #51) unless told otherwise.

Recommended Next Step

• Get the #38 scope decision, implement it, then move to #37 (Bitbucket provider) per the previously agreed order (39→38→37, all done).
