…ver (fixes #4523) Route the persistence doctor's URL->backend detection through the tested PraisonAIDB._detect_backend instead of hand-rolled substring sniffing. Doctor-specific lenient fallbacks (sqlite/qdrant/memory and the chroma special-case) are retained via a CLI-local wrapper. Co-authored-by: MervinPraison <MervinPraison@users.noreply.github.com>

Confidence Score: 5/5The PR appears safe to merge, with no concrete changed-code defect identified. The doctor now uses the same backend resolver as the live persistence path, while unknown URLs continue to receive the existing store-specific fallback behavior.

Catch only resolver validation errors.
The outer store-test handlers already catch unexpected exceptions. This broad handler also hides import failures and resolver bugs, then selects sqlite, qdrant, or memory as if the URL were unknown. The doctor can probe the wrong backend and report a misleading result. Remove this handler and keep the documented ValueError fallback.

Confirmed against current head 924e1fd: the broad handler masks resolver/runtime defects, while the outer store-test path already owns unexpected-error reporting. I reproduced this with a RuntimeError regression (it was swallowed before the change) and verified the minimal fix—remove only except Exception, retain the documented ValueError fallback—with 53 focused tests passing. I have read-only access to this PR head, so a branch writer will need to apply the equivalent two-line removal before merge.

@dajiaohuang, thank you for the validation. The finding remains valid until a branch writer removes except Exception. Keeping only the ValueError fallback lets the outer store-test handlers report import failures and resolver defects correctly.

Summary
The
persistence doctorCLI helpers hand-rolled their own URL→backend detection, which had drifted from the canonical, testedPraisonAIDB._detect_backend. This consolidates behind the single source of truth while preserving the doctor's lenient fallbacks.Changes
_detect_store_backend(url, default)incli/features/persistence.pythat delegates toPraisonAIDB._detect_backendinside atry/except, falling back to a doctor-specific default onValueError._test_conversation_store→ defaultsqlite._test_knowledge_store→ keepschromaspecial-case, defaultqdrant._test_state_store→ defaultmemory.Why
The doctor now recognises the same schemes as the live path (
libsql://→ turso,*.supabase.co→ supabase,weaviate), which the copies previously mislabeled assqlite/qdrant. No public API, CLI surface, or probe behaviour changes.Validation
Verified detection across libsql, supabase, postgres, mysql, sqlite, redis, qdrant, weaviate, and unknown-scheme fallbacks — all resolve as expected.
