Honcho
Sibyl vs Honcho: same 42k corpus, same 250-question suite
Sibyl passes more questions with 4.5x smaller average context and an estimated Sonnet cost about 3.5x lower.

Read the pageMem0
Mem0 retrieves 92/350 and reaches 105/350 after Sonnet, with 1,720 average context tokens and about 92 minutes of ingestion.
Read the pageHindsight
Hindsight passes 152/350 in retrieval and answers, with 11,892 average context tokens and 98 minutes of ingestion.
Read the pageMnemosyne
Mnemosyne passes 5/350 in retrieval and 55/350 after Sonnet, but this result should be read carefully because vectors are disabled.

Sibyl
I would rather not open with a leaderboard. The honest starting point is the control run: a year of synthetic business life, 500 companies, 1,500 stakeholders, 209,000 write calls, and the one question I keep coming back to. Can an agent retrieve current operational state without dumping the whole past into the prompt?
Read the test noteHoncho
Honcho is the page I would show first to a technical reader, because it is closest to a real head-to-head: same 42k corpus, same 250 questions, same Sonnet model. The scar is visible too: the runner probably under-waits Honcho async processing.
Read the test noteMem0
The Mem0 story is really about cost, not a dunk. The local baseline I tested is real and reproducible, and limited on purpose. A stronger Mem0 mode exists, but the reports put a price tag on it: extraction stops being a footnote once the corpus hits 41M tokens.
Read the test noteHindsight
Hindsight is the subtle page. It does not collapse like a bad retrieval toy. It finds meaningful memories. The problem is that it often sends so much context that Sonnet becomes the expensive part of the memory system.
Read the test noteMnemosyne
This is the page where storytelling needs restraint. The number looks brutal, but the report also says vectors were disabled. The honest story is not victory-lap content. It is a warning label plus a next rerun.

25 PASS, 6 strict FAIL. Four failures are confirmed symlink/cross-profile isolation issues; two are harness exception failures.

The 0.4.17 retest is mixed: selected prompt-boundary escapes are fixed, while symlink isolation, migrated secret prefetch and learning-reference cases still need patch confirmation.

1 high, 2 medium, 1 low. The code is considered well hardened for such a young project, but several points still need fixes.
