Espejo (Mirroring)

Coach Let me analyze this scenario. The user is practicing the Mirroring (Espejo) technique from Chris Voss's "Never Split the Difference" (Rompe la barrera del no).

The scenario: A client doubts the price in a sales meeting. Hidden pressure: budget pressure and a cheaper competitor.

Transcript:
- ASSISTANT (client): "Mira, aprecio la propuesta, pero el precio no me cierra." (Look, I appreciate the proposal, but the price doesn't work for me.)
- USER (student/seller): "No me cierra?" (Doesn't work for you?) — This is a good mirror! Repeating key words.
- ASSISTANT: "El número es más alto de lo que esperaba, francamente." (The number is higher than I expected, frankly.)
- USER: "Que esperabas?" (What did you expect?) — This is a mirror-ish attempt but grammatically it's a bit off. It's mirroring "esperaba" but phrased as a question "What were you expecting?" It's actually a decent mirror + calibrated question hybrid. But it could be better — it sounds slightly interrogative/challenging. Actually "¿Qué esperabas?" as a mirror of "más alto de lo que esperaba" is okay, but the tone matters. Chris Voss would say mirror should be 1-3 words repeated, said with inquisitive tone.
- ASSISTANT: "Algo más ajustado a mi presupuesto, la verdad. Y te soy honesto: tengo otra oferta sobre la mesa bastante más barata." (Something more adjusted to my budget, honestly. And I'm being honest: I have another offer on the table much cheaper.)

So now the client revealed black swans: budget constraint and a competitor offer. The user's mirrors worked — the client revealed the hidden pressures! That's a success.

Now I need to evaluate the last performance and respond ONLY with valid JSON with keys:
- bueno (what they did well, concrete)
- malo (concrete error)
- frase_modelo (better alternative phrase)
- ensenanza (book teaching applied to this moment)
- truco (practical trick for sales/negotiation)
- guia (mini guide 2-3 steps for next turn)
- aprendizaje (memorable lesson to take away)

Evaluation:
Good: The user used the mirror twice. "No me cierra?" is a classic mirror that got the client to elaborate. "Que esperabas?" continued drawing out info. Result: client revealed budget pressure and competitor offer — two black swans surfaced without the user asking probing "why" questions.

Bad/Error:
1. The mirror "¿Qué esperabas?" slightly shifted from mirror to calibrated question — it's fine but the phrasing "Que esperabas" without the inverted question marks and with a potentially challenging tone could sound like a challenge ("What did you expect?!"). Actually in Spanish, "¿Más alto de lo que esperaba?" would have been the purer mirror. The user changed "lo que esperaba" to "que esperabas" which is a slight reformulation — still works as mirror-ish.
2. More important: after the client revealed the competitor offer, the natural error would be to now jump to defending price or discounting. But the transcript ends there, so the "malo" should be about the last user turn. Hmm, the last user turn is "Que esperabas?" — the error: it verges on a "why/what" challenge that can sound confrontational; a purer mirror would be "¿Más alto de lo que esperaba?" Also, missing labeling — could combine mirror with a label to soften.

Actually, let's think: the technique focus is Espejo. The user did two mirrors. The second one "¿Qué esperabas?" is more of a calibrated question (What) than a mirror. It's not wrong per se, but the critique could be: the mirror should repeat their words, not rephrase — "¿De lo que esperaba?" or "¿Más alto de lo que esperaba?" keeps their language and tone inquisitive, whereas "¿Qué esperabas?" can sound like a challenge to justify.

Also there's a missed

El alumno aplicó dos espejos que funcionaron: el cliente pasó de 'no me cierra' a revelar dos cisnes negros (presupuesto ajustado y competidor más barato). El fallo principal: el segundo espejo fue una reformulación ('¿Qué esperabas?') que roza el interrogatorio, y
