53	49
54	50		## Mandatory Surprise
55	51
56		-	[RESOLVED] The Rhai plugin runtime had no HTTP request limits or timeout enforcement.
57		-
58		-	All four gaps have been fixed in `host_functions.rs`:
59		-
60		-	- Request count limit: `MAX_REQUESTS_PER_FETCH = 100` with `check_request_limit()` on every HTTP call.
61		-	- Response size cap: `MAX_RESPONSE_BYTES = 2 MB` via `.take()` on response reader.
62		-	- URL restriction: `validate_url()` blocks non-HTTP schemes and localhost/private ranges (10.x, 192.168.x, 172.16-31.x, 169.254.x, [::1], 0.0.0.0).
63		-	- Aggregate fetch timeout: `MAX_FETCH_DURATION = 60s` with `check_fetch_deadline()` (AtomicU64 epoch-ms deadline) checked on every HTTP call. Prevents 100 x 15s = 25 min worst case.
	52	+	Keychain migration race condition (crypto.rs:74-85).
64	53
65		-	Verdict: Resolved. The most significant gap in the codebase has been fully addressed with defense-in-depth limits at multiple layers.
	54	+	The keychain migration path reads the old encryption key from disk, stores it in the OS keychain, then deletes the disk file. If the process crashes between the keychain store and the disk delete, the key exists in both locations -- this is fine (idempotent on next run). However, if the process crashes between reading from disk and storing in the keychain, the key is only on disk -- also fine (retry on next startup).

77		-	\| Cold spots \| 5 \| 5 \| 2 \| 8 \| 5 \| 4 \| 4 \| 1 \| 0 \|
	56	+	The actual race condition is: if two instances of the app start simultaneously during migration, both read the disk key, both try to store in the keychain, and one may overwrite the other's store. Since both are storing the same key value, this is technically safe, but the second instance may also try to delete the disk file while the first is still reading it. On macOS, this is a benign race (the file handle remains valid), but on Windows, the delete could fail or cause the first instance's read to fail.
78	57
79		-	---
	58	+	Verdict: Low practical risk -- simultaneous app launches during first-time migration is unlikely. But the migration should use a file lock or atomic rename to be fully correct.
80	59
81		-	See [audit_history.md](./audit_history.md) for full chronological audit log.

82	61
83		-	---
	62	+	Rhai plugin runtime HTTP limits -- all 4 gaps resolved (request count limit, response size cap, URL restriction, aggregate fetch timeout). Verdict: Resolved.
84	63
85	64		## Strengths
86	65
87	66		- Zero `.unwrap()` in business logic. Every fallible operation uses `Result`, `unwrap_or_else`, or `unwrap_or_default` with reasoning comments. Only 4 unwrap/expect in startup/static contexts.
88	67
89		-	- All SQL is parameterized. Every query in `repository.rs` (1,822 lines) uses `?N` placeholders with `.bind()`. The `sanitize_fts_query` function wraps search terms in double quotes to prevent FTS5 operator injection. Dynamic placeholder strings built safely.
90		-
91		-	- Defense-in-depth security. Multiple independent layers: Rhai engine sandboxed (100k ops, depth 128), AES-256-GCM encryption for secrets at rest with versioned format, HTML sanitization strips dangerous elements, XML escaping in OPML export, URL tracker parameter stripping, extensive input validation.

95		-	- Comprehensive test suite (602 tests). Coverage spans crypto roundtrips, FTS5 search, feed health, tag CRUD, stale cleanup, upsert conflict, plugin manager lifecycle, Rhai conversions (50+ tests), ordering (25 tests), generator pagination, command integration (50 tests), sync service.

	78	+	### 1. ~~Massive test count regression (-392 tests)~~ (False finding)
	79	+	Audit ran `cargo test` without `--workspace`. BB uses `default-members = ["src-tauri"]`, so only 210 of 601 tests were counted. Verified 2026-04-22.

103		-	- ~~No circuit breaker.~~ Circuit breaker implemented (migration 008, threshold 10, skip in auto-fetch, reset API, event emission).
	81	+	### 2. ~~bb-feed has 0 tests~~ (False finding)
	82	+	bb-feed has 110 tests. Same `--workspace` issue. Verified 2026-04-22.
104	83
105		-	- ~~Sync changelog unbounded growth.~~ Changelog cap at 10,000 entries with `enforce_changelog_retention()` on sync tick.
	84	+	### 3. ~~Manual XSS risks~~ (False finding)
	85	+	All user content (feed titles, authors, descriptions, tags) escaped with escapeHtml()/escapeAttr(). Rich HTML body uses sanitizeHtml(). Verified 2026-04-22.
106	86
107		-	- ~~Zero automated JS tests.~~ 55 JS tests covering state management, utilities, sources sidebar rendering, items rendering, and settings-sync 4-state flow.
	87	+	### 4. ~~FTS query injection~~ (False finding)
	88	+	sanitize_fts_query wraps every word in double quotes, which neutralizes all FTS5 operators including NEAR and column: prefixes. Tests confirm this at lines 1862-1874 of repository.rs. Verified 2026-04-22.
108	89
109		-	- FTS query sanitization gaps. `sanitize_fts_query` strips standard operators but may not cover `NEAR` or `column:` prefix syntax. Low risk (local DB) but incomplete.
	90	+	### 5. ~~Sparse documentation~~ (Fixed)
	91	+	All public items now have `///` doc comments. 14 doc files in docs/. Fixed 2026-04-22.

162		-	### Overall Doc Grade: A
	157	+	### Overall Doc Grade: B-
163	158
164		-	Clean doc set. README and plugin_authoring.md are good additions from recent audit work. Main issue was stale test count in todo.md (106 vs 225 actual). description.md is an intentional placeholder.
	159	+	Doc set exists but is sparse in some areas. Changelog only partially maintained. Module docs need expansion.
