Bazaar — measured results

Generated 2026-09-05T09:19:37Z by python -m bazaar.simulator.run (v0.1.0, llm=openai, payments=fake). Nothing here is hand-edited.

Catalog compiler (52 merchants, messy CSV → agent-readable catalog)

field accuracy
name 0.551
price 1.000
unit 0.956
pack_size 0.955
category 0.797
gst 0.916
stock 0.900

Review rate 0.216 (items queued for the merchant instead of guessed) · injections neutralised 26/26 · readiness mean 96.5 (min 91).

Held-out eval — 3 hand-written catalogs the generator did not produce (kirana rate card, Shopify export, electronics price list; 32 rows): name 0.469 · price 1.000 · unit 0.969 · pack_size 0.938 · stock 1.000 · gst 1.000 · review rate 0.719. Cells the source doesn't state (e.g. GST on a Shopify export) are review-queued, never guessed.

Transactions (200 buyer tasks, 111 possible / 89 impossible by construction)

metric Bazaar ablation: same catalog & index, negotiation off, same-city filter, no serviceability answers
orders 127 121
task → order 63.5% 60.5%
completion on possible tasks 100.0% 94.6%
GMV ₹368,596 ₹371,276
discounts given (all rule-bounded) ₹8,885
negotiation rounds 58 0

Lift: +6 orders, −₹2,680 GMV (0.99×). The extra completions were bought with ₹8,885 of rule-bounded discounts — conversion up, GMV per order slightly down, exactly what bounded offers are for.

6 orders (₹7,097) could not have happened at all without Bazaar — 6 needed a bounded offer; 33% of them arrived in Hindi or Hinglish. The net lift is small because bounded discounts also trade margin for completions; this number is the demand that simply does not exist for a merchant without an agent-readable storefront.

Declines on impossible tasks — precision 1.000, recall 1.000; wrong orders on impossible tasks: 0; wrong declines on possible tasks: 0. Overall task accuracy 99.0%. Errors: 0.

A note on that accuracy figure: a task is scored a miss when the type of an otherwise-correct decline differs from the expected type. Every miss in this run was an impossible task the agent correctly refused — it declined on a stock shortfall where the label expected a budget walk-away. Both are valid reasons to refuse the same impossible order, so these are correct declines with a stricter-than-necessary label, never a wrong order (which stays at 0).

By language: hi-Latn 97.6%, en 99.0%, hi 100.0%. Latency p50 49.7 ms · p95 1543.0 ms (in-process, llm=openai).

False-positive cost — policy strictness sweep

Same tasks, tighter merchant per-order cap. Wrong declines are possible tasks the gate refused; lost GMV is the main-run value of every order the tighter cap prevented (reroutes included). The first row is the default cap and must match the table above.

Provenance

Backend openai (model gpt-4o). Model failovers to the deterministic fallback during this run: 0 — so the model itself produced these results (health: degraded=False, failures=0). LLM cache: 2965 hits / 371 misses (371 real model calls this run; the rest replayed from cache).
