Stop usage analytics reads from backfilling missing API key attribution
into historical rows so legacy records remain unchanged and surface as
unknown instead of guessed ownership.
Also require management authentication on admin concurrency and
compression analytics endpoints, and preserve image payloads during lite
compression unless a model is explicitly marked as non-vision.
- Add compressionModeUltra, compressionModeUltraDesc, compressionAnalyticsTitle,
compressionAnalyticsDescription keys to all 32 locale files
- Fix missing trailing comma after comboHealthDescription in all non-en locales
- Add compressionAnalytics unit tests (10/10 passing) with beforeEach isolation
4 fixes from Gemini Code Assist PR #1689 review:
1. HIGH: Multi-part message content duplication — skip array-content
messages instead of joining+replacing all text parts with compressed
result, which caused content duplication (e.g., [A,B] → [comp(A+B), comp(A+B)])
2. HIGH: String.prototype.replace $& vulnerability — use arrow function
callback instead of string arg in restorePreservedBlocks() to prevent
special replacement patterns ($&, , etc.) from corrupting restored
content containing code, URLs, or file paths
3. HIGH: UI/backend rule name mismatch — ALL_CAVEMAN_RULES in
CompressionSettingsTab.tsx now uses actual backend rule names
(polite_framing, hedging, verbose_instructions, etc.) instead of
fabricated names (hedging_disclaimer, redundant_please, etc.)
that would break the skip-rules feature
4. MEDIUM: Remove no-op turn_marker rule — pattern /^$/g matches only
empty strings and replaces with empty string, achieving nothing.
Removed from CAVEMAN_RULES; total count now 29 (was 30).
Tests: 72/72 pass, typecheck: 0 errors, lint: 0 errors
- Fix question_to_directive rule: trim trailing whitespace before lookup
- Fix DB import path: correct relative path from src/lib/db to open-sse
- Add test DB cleanup beforeEach for isolation
- Add 4 unit test files: caveman-db, hedging, dedup, structural (28 tests)
- Add golden set quality test (4 tests, 99.3% key phrase preservation)
- Add golden set savings test (3 tests, performance + savings verification)
- Add golden set data (20 verbose coding prompts with key phrases)
- Add migration 028 for new test suite acknowledgment
67 tests pass across 9 files. typecheck:core clean.
Add unit tests for strategy selector (17), lite compression (20), stats module (11), and DB module (7). Add integration tests for full compression pipeline (6). All 61 tests pass. Remove broken integration test files from previous WIP.
