Replaced with a versioned NATIVE namespace (SCHEMA_NS = 'schema-v2') on both the upserted vectors and the query: native namespaces need no metadata index and exclude every stale cohort at the source, so no topK slot is ever spent on a discarded match and the filter is gone. The version is in the vector ids too, so re-indexing writes a new cohort and a Worker rollback keeps working against the old one. An un-reindexed environment gets zero matches → the documented full-dictionary fallback. Also from the self-review: the stale module header still said trap-rules are embedded; system-prompt tests fed trap strings retrieval can no longer produce; and no test entered through the composed seam — added a retrieveSchemaContext → buildSystemPrompt test seeded with the real corpus asserting every DATA_TRAP renders exactly once (negative-controlled: re-adding traps under a disguised id/kind fails it and the new corpus-length assertion).

It now routes through the real write path into a recording fake, retrieves the WHOLE corpus, and derives its score from the floor — so the write→read metadata contract (text key, ids, namespace) is under test and a trap re-added at any position under any id/kind fails it (negative-controlled again with a tail-appended, table-kind trap). Also: remaining fixtures moved off pre-v2 unversioned ids; the semanticSearch test title no longer claims a namespace it does not use (it pins the entity METADATA filter); the module header no longer claims the bindings satisfy the structural types (the route casts — drift is not tsc-checked); the new-cohort rollback guarantee is now correctly stated as bump-only, with an explicit WHEN TO BUMP rule (in-place upserts, positional query ids, orphan risk); the README no longer suggests purging a cohort inside its rollback window and notes delete-vectors needs an explicit id list; dropped the stale '150 теста' verification claim. --- apps/web/app/lib/assistant/README.md | 18 +++++--- apps/web/app/lib/assistant/rag.test.ts | 14 +++--- apps/web/app/lib/assistant/rag.ts | 19 +++++--- .../app/lib/assistant/system-prompt.test.ts | 44 ++++++++++++------- 4 files changed, 59 insertions(+), 36 deletions(-) diff --git a/apps/web/app/lib/assistant/README.md b/apps/web/app/lib/assistant/README.md index a140334ba..4f240f42f 100644 --- a/apps/web/app/lib/assistant/README.md +++ b/apps/web/app/lib/assistant/README.md @@ -25,7 +25,8 @@ | `agent.ts` | Vercel AI SDK glue: BgGPT през AI Gateway + `streamText` | §2/§9.5 | typecheck | | `routes/assistant.chat.tsx` | Stateless chat ресурс route | §2/§5 | typecheck | -**Проверено:** `pnpm --filter web typecheck` → 0; **150 теста** преминават; `pnpm audit --audit-level=high` +**Проверено:** `pnpm --filter web typecheck` → 0; целият тестов пакет на `apps/web` преминава (бройката +расте с всяко ревю — не я кодираме тук, `pnpm --filter web test` я показва); `pnpm audit --audit-level=high` чист; Prettier чист.

Опционален quote клас след името затваря и трите форми (adversarial тестове; негативен контрол: падат без промяната). Идентификатор с padding в кавичките е РАЗЛИЧЕН за SQLite и не резолва built-in — не изисква обработка (бележка от ревюто). --- apps/web/app/lib/assistant/sql-guard.test.ts | 17 +++++++++++++++++ apps/web/app/lib/assistant/sql-guard.ts | 8 +++++++- 2 files changed, 24 insertions(+), 1 deletion(-) diff --git a/apps/web/app/lib/assistant/sql-guard.test.ts b/apps/web/app/lib/assistant/sql-guard.test.ts index c15c3c3b5..38ad35199 100644 --- a/apps/web/app/lib/assistant/sql-guard.test.ts +++ b/apps/web/app/lib/assistant/sql-guard.test.ts @@ -130,6 +130,23 @@ describe('assertReadOnlySelect', () => { } }); + it('rejects QUOTED denylisted function names — SQLite resolves "group_concat"(x) as the function (review f/u)', () => { + // Modern SQLite (D1) resolves a double-quoted, bracketed, or backticked identifier in call + // position to the same built-in, so `"group_concat"(name)` reached the aggregate while the + // bare-name regex saw only `group_concat"(` and let it through (review, ydimitrof). + for (const sql of [ + 'SELECT "group_concat"(name) FROM bidders', + 'SELECT [group_concat](name) FROM bidders', + 'SELECT `group_concat`(name) FROM bidders', + 'SELECT "printf"(\'%1000000d\', id) FROM contracts', + 'SELECT "string_agg" (name, \',\') FROM bidders', + ]) { + const r = assertReadOnlySelect(sql); + expect(r.ok, sql).toBe(false); + if (!r.ok) expect(r.reason).toMatch(/function not allowed/); + } + }); + it('strips comments without corrupting string literals (review #80, follow-up)', () => { // A `/* */` or `--` INSIDE a single-quoted literal is data, not a comment: a literal-unaware strip // changed `'a/*b*/c'` to `'a c'` (wrong rows) and truncated `'x -- y'` (fail-closed false-deny). diff --git a/apps/web/app/lib/assistant/sql-guard.ts b/apps/web/app/lib/assistant/sql-guard.ts index 22da9ba2b..da5b1b0ab 100644 --- a/apps/web/app/lib/assistant/sql-guard.ts +++ b/apps/web/app/lib/assistant/sql-guard.ts @@ -177,8 +177,14 @@ export function assertReadOnlySelect(rawSql: string): GuardResult { // memory before capRows sees the row; no analytics query needs any of them (review #80, red-team R2; // printf/format + aggregate + string_agg alias f/u, ydimitrof).
