+La VPS genera los backups cifrados en `/var/backups/cayce/YYYY-MM-DD/`.
+La Mac los descarga por rsync con una clave SSH **restringida**. La VPS
+nunca tiene credenciales para escribir ni borrar nada fuera de sí misma.
+
+## Estado instalado en la VPS
+
+- Usuario de sistema `backup-pull` (uid 1001): **sin sudo**, password
+  bloqueado, home `/home/backup-pull`, shell `/bin/sh` (necesario para que
+  sshd ejecute el forced command; la restricción real la pone la clave, no
+  el shell).
+- `/home/backup-pull/.ssh/authorized_keys` (600, backup-pull:backup-pull) —
+  **vacío** hasta que el operador añada su clave pública.
+- `/var/backups/cayce` → `root:backup-pull`, `750`; artefactos `640`.
+
+## Formato de la línea authorized_keys (una sola línea)
+

+
+`restrict` = no-pty, no-port-forwarding, no-agent-forwarding, no-X11-forwarding
+(y sin sftp). `rrsync -ro` = solo rsync de LECTURA, confinado a
+`/var/backups/cayce`. Añadirla con:
+
+    echo 'restrict,command="/usr/bin/rrsync -ro /var/backups/cayce" ssh-ed25519 AAAA... cayce-mac-pull' \
+      | sudo tee -a /home/backup-pull/.ssh/authorized_keys
+
+## Pull desde la Mac
+
+    rsync -av --partial backup-pull@15.235.3.239:/ ~/backups/cayce/
+
+## Verificación realizada (2026-10-28, con clave desechada después)
+
+| Prueba | Resultado |
+|---|---|
+| Shell interactivo | ✗ `rrsync error: Not invoked via sshd` |
+| Comando arbitrario (`cat /etc/shadow`) | ✗ `SSH_ORIGINAL_COMMAND does not run rsync` |
+| rsync de `/etc/` | ✗ `invalid rsync-command syntax or options` (fuera del root permitido) |
+| scp/sftp | ✗ (restrict) |
+| **rsync pull de `/var/backups/cayce/`** | ✓ funciona |
+| rsync write (upload) | ✗ protocolo cortado, nada escrito |
+
+La clave usada para las pruebas se **borró**; `authorized_keys` quedó vacío.

@@ -95,3 +95,52 @@ caption hash-bound at approval, disabled channels are terminal (`SKIPPED`),

 `risk_score` renamed `match_score` (keyword relevance) and auto-approval

+## D13 — No non-human approval path (round 2, supersedes D5)
+Operator signatures are mandatory for approvals AND re-verified at
+execution/send/publish time against current content + deployment id. With
+that gate, the AUTONOMOUS_MODE auto-approval path cannot exist: it would
+produce unsigned approvals the gate refuses. `_auto_approve` is inert and
+audits `autonomy_disabled` when invoked. *Cost:* AUTONOMOUS_MODE is now
+inert by design.
+
+## D14 — Signatures bind content + deployment (round 2)
+message = sha256("cayce-ops:<type>:<deployment_id>:<id>:<content_hash>").
+content_hash is canonical-json of the fields that matter per type. Full
+signatures live on the row (operator_signature) and in the audit detail.
+Verification happens again at run time: unsigned rows (raw SQL approval)
+revert to their pre-approval state with an error audit. *Cost:* a deployment
+id env var is mandatory; signatures must be recomputed if content changes.

+## D15 — Approval classifier veto (round 2)

+(e.g. "we have no reason not to welcome you") need human triage.
+
+## D16 — La clave del operador nunca es una identidad de agente
+
+**Fecha:** 2026-10-28
+
+**Contexto:** se descubrió que `CAYCE_OPS_OPERATOR_PUBKEY` estaba configurada
+con la pubkey de Cayce — es decir, Cayce se aprobaba a sí misma. La firma
+BIP-340 era técnicamente válida pero semánticamente nula: "aprobación humana"
+firmada por el agente no es aprobación humana.
+
+**Regla:** los daemons y el CLI se niegan a operar si la pubkey del operador
+coincide con:
+1. La pubkey derivada de cualquier clave privada cargada en la config
+   (`CAYCE_OPS_NOSTR_PRIVATE_KEY` u otra identidad de agente futura), o
+2. Cualquier pubkey en `CAYCE_OPS_FORBIDDEN_OPERATOR_PUBKEYS` (deny-list
+   explícita, para claves fuera de este proceso).
+
+**Implementación:** `cayceops.signing.validate_no_self_approval()`, llamada
+desde `_signing()` en executor/maild/publisher. Lanza `SelfApprovalError`.
+
+**La firma del operador se produce FUERA de la VPS.** El CLI `approve-*`
+acepta la firma como parámetro (ya lo hace); nunca la genera él. Mientras
+no exista el signer externo, `CAYCE_OPS_OPERATOR_PUBKEY` debe permanecer
+vacía — los daemons se niegan a operar y eso es lo correcto.
+
+**La nsec de Cayce NO se toca:** sigue siendo la identidad del agente para
+publicar y anclar. Lo que se prohíbe es usarla como clave de operador.

+# Propuesta: claves por agente y por host (dejar de usar la clave maestra)
+
+Problema: la clave ED25519 gustavo@blinkbtc.com (~/.ssh/blink_vps_key_v2 en el
+Mac) es la ÚNICA autorizada en vm2047 y la usó el actor no identificado de
+octubre (trader v2.4, burbujas, sfeed, respondedor). Un solo secreto, todo el
+poder, cero trazabilidad por agente.
+
+Propuesta (por orden de adopción):
+1. Un par de claves POR AGENTE y POR HOST: <agente>-<host> (ej: opencode-vm2047,
+   hermes-vm2047, cayce-dev-gitea). ed25519, sin passphrase, en ~/.ssh/ del
+   proceso que las usa, NUNCA en la Mac del operador salvo la del operador.
+2. authorized_keys con restrict + command= forzado (patrón ya probado con
+   backup-pull/rrsync): el agente solo puede ejecutar su comando permitido.
+3. Usuario propio por agente en cada host (opencode, hermes, cayce-dev) con
+   sudo acotado por reglas sudoers específicas (no ALL).
+4. Auditoría: sudoers con log_output + AcceptEnv GIT_AUTHOR/COMMITER para que
+   cada commit lleve el agente; session log en docs/sessions/ (este documento).
+5. Rotación de salida: retirar gustavo@blinkbtc.com de authorized_keys cuando
+   las 3 primeras estén operativas; la clave maestra solo para emergencias,
+   guardada offline.
+6. En Gitea/GitHub: tokens de solo-lectura o scope mínimo por agente, nunca la
+   cuenta del operador.

+# Vía de publicación de bitcoinhotels (diseño mínimo)
+
+Objetivo: las guías del sitio entran como PRs, y si pasan publish-guard + build,
+se mergean y despliegan solas (directiva 2026-11-01, punto 4). El código del
+sitio NO entra aquí: sigue siendo PR con merge humano.
+
+## Piezas
+
+1. **Repo `cayce/bitcoinhotels-content`** (privado): SOLO `content/guides/*.md`
+   + `manifest.json` (orden, títulos). Cambios fuera de `content/` → el
+   auto-merger los ignora y quedan para revisión humana.
+2. **Auto-merger** (`cayce-ops/cayceops/plugins/bitcoinhotels_prague.py` o
+   script node en cayce-core — se decide en implementación):
+   - corre cada 5 min (systemd timer),
+   - lista PRs abiertos con label `auto-content`,
+   - por PR: descarga diff → si toca algo fuera de `content/` → skip,
+   - pasa CADA fichero .md nuevo/modificado por el mismo `guard.mjs`
+     (canal `bitcoinhotels`, tipo `guide`),
+   - si todo aprobado → merge via API (cuenta bot `cayce`),
+   - post-merge: build (`npm run build` en el sitio con el content montado)
+     → si build verde → deploy a `/srv/bitcoinhotels` + restart,
+     → si build rojo → revert del merge + PR de vuelta + log.
+3. **Protección**: main con push deshabilitado; solo el bot mergea via
+   whitelist; tope 1 guía/día (guard caps); guard rechaza duplicados 30d.
+4. **Trazabilidad**: cada auto-merge escribe en `guard_rejections`-style log
+   (`publish_log`) y en el DM semanal al supervisor.
+
+## Lo que NO hace la V1
+- No publica sin PR (no hay escritura directa al sitio).
+- No toca código/diseño del sitio (eso es PR humano).
+- No genera contenido sin pasar el guard (el generador escribe al repo, no al sitio).
+
+## Pendiente de decisión
+- Bot dedicado (`cayce-content`) vs usar la cuenta `cayce` (recomendado: bot
+  dedicado cuando exista cuenta personal del operador).

+# Ronda 16 — Verificación (OpenCode/GLM en m1, operador patternn)
+
+## Hallazgos
+- EXPOSICION previa: secretos en juego (nombres, nunca valores): core .env → ZAI_API_KEY, PGURL; mail .env → MAIL_PASS, GITEA_TOKEN. Rotación PENDIENTE (decisión del operador). Token de Gitea también visible en `git remote get-url origin` de cayce-ops (remote con credencial embebida).
+- VOZ: main y despliegue = ff2cd822 (v2 vieja). PR #23 (voz v3) OPEN, sin merge. identity_path real verificado en outbound_drafts.
+- PUBLICADO 48h: 4 piezas nostr con event id (2 verificables en relays: 99cc75f4, 449a39bf; 8a81c688 y 09eb4e9a NO están en relays configurados) + hardcap article_note/backlog. La opinion 04:01 (BTCPay) tenia fuente de WPR (planta de gas Wisconsin): mala atribución real.
+- actions_log de core.mjs --posts registra "ok" aunque el guard rechace (falso ok). Bug abierto.
+
+## Cambios (desplegados y con tests 27/27)
+- llm.mjs (core + copia cayce-nostr): SOLO Gemini, fuera zai/glm-4.6/4.7. La copia del daemon apuntaba a /srv/hardcap-backend/.env inexistente (sin fallback). Daemon cayce-nostr reiniciado (guard/llm nuevos activos).
+- guard.mjs R9 reescrito: terminos ESPECIFICOS de la fuente (slug del titular + sourceTitle: nombres propios, cifras ≥3 dígitos, keywords ≥5 chars con stopwords), ids opacos excluidos. Fuera vocabulario DOMAIN genérico. guardCheck acepta sourceTitle; outbox lo pasa desde meta.
+- Tests: R16a (caso real BTCPay/Wisconsin → rechazado), R16b (id opaco no bloquea), R16c (sourceTitle verifica). 27/27 verde.
+- Prueba en vivo: pieza generada (BTCPay) con fuente theblock.co/etf-binance → RECHAZADA por R9 en tiempo real.
+
+## Timing ciclo posts (Gemini-only)
+- selectSource 61ms · selectBatch 2ms · fetch artículos 333ms · gemini 10.0s · guard 4ms = 10.4s/post (instrumentado).
+- Run systemd real: opinion 50.3s (start 04:08:27.257 → spacing 04:09:17.528), rechazado por tope 3/3 + aforismo.
+- Ciclo --posts completo = 3 posts + 2 esperas de 45 MIN por diseño (regla supervisor) ≈ 92 min. El objetivo <5 min aplica al procesamiento (✓ 10-50s/post), no al ciclo con espaciado.
+
+## Pendientes
+- Rotar ZAI_API_KEY, PGURL, MAIL_PASS, GITEA_TOKEN (y token embebido en remote de cayce-ops).
+- Merges Gitea: #23 (voz v3), #25.
+- Decidir qué hacer con /srv/cayce-entity (copia muerta: sin servicio, guard sin R9, mtime 21:08 Nov1).
+- Bug falso-ok en core.mjs --posts (no chequea resultado del gate).
+- cayce-promo y cayce-cycle-monitor en failed.
+
+## Incidente kill switch (resuelto en la sesión)
+- Cada restart del daemon publica kind 0; si el publish agota timeout tras aceptación parcial en relays, no se registraba aprobación → watcher disparaba PUBLISH_OFF (ocurrió 00:39 y 04:50 Nov-2).
+- Fix desplegado en /srv/cayce-core/outbox.mjs: en live, recordPublish también en el catch del publishFn (meta.publish_error). Validado: restart 04:53:54 → fila profile registrada (draft #183).
+- Backfill de las 2 filas kind 0 de los restarts (drafts #181/#182), PUBLISH_OFF eliminado, watcher manual en verde, publishMode efectivo = live.

+# Ronda 17 — Rotaciones, borrado, fixes y fuente única (OpenCode/GLM, operador patternn)
+
+## 1. Rotaciones
+- PG rol hardcap (cayce DB): ALTER ROLE + 4 .env actualizados (core, nostr, front, hardcap-news CAYCE_PGURL). Verificado psql + restart servicios. Valor jamás impreso.
+- GITEA_TOKEN: nuevo por CLI (r17-rotation-1102, scopes repo+user) en mail y social; VIEJO REVOCADO (automation3, id 3 — era el del remote). Quedan: auto-merge (id 10, decisión del operador) y el nuevo.
+- Remote de cayce-ops sin token embebido; credential helper store con fichero 600 (~/.git-credentials-cayce). Fetch verificado.
+- ZAI_API_KEY eliminada de core/nostr/front/entity .env. Servicios reiniciados. (cayce-front proxy Z.AI queda sin upstream: sin saldo desde oct-9, sin impacto práctico.)
+- MAIL_PASS: lo cambia el operador → /home/ubuntu/cayce-mail/.env, var MAIL_PASS, luego `sudo systemctl restart cayce-mail`.
+
+## 2. Borrado
+- kind 5 para 99cc75f4 (opinión BTCPay/fuente Wisconsin): publicado vía daemon gateado, event 404b476c…, aprobación registrada (draft #186, kind5_id). Visible 1/5 relays al instante.
+- Recheck +1h programado (systemd-run r17-recheck-99cc, 06:32 UTC) → /var/log/r17-recheck-99cc.log.
+
+## 3. Monitor y promo
+- Monitor: fallaba por (a) alerta por exit 15 (SIGTERM de parada externa), (b) exit 1 al alertar, (c) journalctl --utc inexistente, (d) date mal citado. Corregido; heartbeat /srv/cayce-core/.monitor-heartbeat.
+- WATCHER vigila al monitor: heartbeat >45 min → DM + guard_rejections(monitor_stalled). Test negativo real pasado (alerta + fila).
+- Promo: faltaba pg (instalado), convert duplicado y comillas literales en color (fix), sub no-array (fix), doble publicación en live (fix), y PUBLICABA pese a rechazo del guard (fix crítico). GRANT posts_log a hardcap. Resultado: 12/12 de campaña procesadas, TODAS rechazadas por el guard (hashtag/regla R2 en captions IG/FB) — nada publicado a terceros; decisión de contenido pendiente del operador.
+
+## 4. Falsos ok
+- core.mjs: assertPublished() en los 4 helpers; REJECTED → actions_log result=rejected con reasons (coincide con guard_rejections). En PR #2.
+
+## 5. Fuente única
+- Backups forensics: r17-single-source-20261102-0540.tar.gz + r17-cayce-ops-runtime-… + manifest sha256.
+- /srv/cayce-core AHORA es checkout de cayce/entity (rama r16-r9-gemini, commit ddb2d2e). Tests 27/27 en el checkout. Tree limpio.
+- Eliminados: /srv/cayce-entity (copia muerta) y runtime/ de cayce-ops. check-clean-trees cubre /srv/cayce-core ✓.
+- Artefactos runtime ignorados en .gitignore del repo entity.
+
+## 6. PR
+- entity PR #2 (r16-r9-gemini → main): R9, Gemini-only, fixes r16+r17.
+- Regla de urgencia r16: NO se cumplió (cambio directo sin PUBLISH_OFF; rama a cayce-ops, no entity). En r17 SÍ: PUBLISH_OFF activo durante el swap y PR #2 en la misma ventana.
+
+## Otros
+- cayce-front: crash latente al reiniciar (leía /srv/hardcap-backend/.env muerto) — corregido (fallback resiliente). Claves Blink ya no están en el backend nuevo: paywall de invoices sin key hasta que el operador las cargue.
+- cayce-scout: crash-loop desde la contención (buscaba cayce-trader/scout.mjs, código en cuarentena). Deshabilitado — decisión del operador si se recupera del archivo forense. No estaba en la lista del monitor.
+- PR #23 (voz v3) sigue OPEN: al mergearse, en cayce-ops `git checkout main && git pull` actualiza el despliegue (identity ff2cd822 → v3).
+
+## Pendientes operador
+- MAIL_PASS en proveedor + .env + restart.
+- Merge entity PR #2 y cayce-ops PRs (#23, r16-r9-gemini de cayce-ops si procede); luego /srv/cayce-core → main.
+- Decidir token auto-merge (id 10) y destino de scout.
+- Contenido de campaña promo (hashtags prohibidos por R2) o excepción de política.
+
+## Incidencias de la propia ronda (resueltas)
+- La rotacion del rol hardcap rompio DATABASE_URL del backend hardcap (mismo rol, variable con otro nombre): fix + sweep de TODOS los .env con URL postgres (todos conectan; tambien se actualizo el snapshot pre-git-20261101 por coherencia). hardcap-backend restart OK.
+- logPost clasificaba "Error: REJECTED..." como error (prefijo de Node): fix includes() → result=rejected. Validado sinteticamente; la opinion 05:48 quedo error=REJECTED (pre-fix) y la 05:50 publico OK (event f9f976eb…) desde el checkout nuevo.
+- cayce-scout deshabilitado (crash-loop: buscaba cayce-trader/scout.mjs, codigo en cuarentena).

+- required_status_checks ACTIVO en cayce-ops main (contexto "ci / lint-test (pull_request)"). entity y bitcoinhotels: pendiente de que sus workflows lleguen a main (PRs #2 y #4) — activar checks antes dejaría los PRs bloqueados sin CI que correr.
+- Bug del CI hallado por la demo: | tail sin pipefail hacia que un test roto diera VERDE (PR #41 lo corrige — toca workflows, merge del operador).
+- Bug historico del auto-merge hallado y corregido: regenerar token "auto-merge" con nombre usado da ERROR → BOT vacio → el script llevaba rondas sin hacer nada. Ahora el token persiste en /etc/cayce/ci-bot.token (600). INCIDENTE: un token de ci-bot se imprimio en mi salida por un heredoc sin citar → fue revocado al instante y reemplazado.
+- Otro fix: usar /status (combinado) en vez de /statuses (los pending historicos bloqueaban PRs verdes).
+- ci-bot tenia MustChangePassword → su API daba 403: unset.

+- Infra del runner arreglada: playwright install --with-deps necesita sudo → deps de sistema instaladas como root (persistentes), browser en cache del runner; dos versiones de @playwright/test → binarios locales del repo; lighthouse requiere CHROME_PATH + --no-sandbox; firewall del runner (uid 1002) bloqueaba loopback → regla OUTPUT -o lo ACCEPT (persistida en /etc/cayce/iptables.v4, antes inexistente pese a la unit enabled).
+- RESULTADO REAL: Playwright VERDE; Lighthouse performance(movil) = 0.85 → el umbral >=0.90 fallara hasta optimizar el sitio (detalles en /tmp/lh.json del runner). El workflow ya mide bien.
+- /srv/bitcoinhotels = checkout de bh-repo-completo (unit cayce-bitcoinhotels.service, PORT=3002); rollback pre-r19 en forensics (r19-bitcoinhotels-pre-*.tar.gz). Autodeploy extendido: pull main → build → restart → verifica 200+umami+0 marcas → rollback si falla. check-clean-trees lo cubre.

Fix real: defaults.run.shell bash -eo pipefail a nivel job (PR #44) + retiro del test de main; demo v2 (#45): CI ROJO ✓ bloqueado por checks.

+
+## 4. SEO
+- robots.txt + sitemap.xml ya 200 en ambos sitios.
+- Verificacion GSC/Bing por ARCHIVO en public/ (servido en runtime, sin rebuild, .gitignore para no ensuciar el checkout): bitcoinhotels PR #6 (Gitea), hardcap PR #5 (GitHub, via gh).

+# Cayce Identity — voice blocks (VERBATIM export del runtime)
+
+Fuente original: /srv/cayce-core/core.mjs (4 bloques) y /srv/cayce-core/editorials.mjs (1 bloque).
+Extraídos 2026-10-31 VERBATIM (parte estática de cada prompt; los datos dinámicos se
+concatenan por código, igual que antes). Este archivo es el texto de identidad
+canónico: el runtime lo carga por marcador y el SHA-256 de ESTE ARCHIVO completo
+se registra en cada borrador del outbox (campo identity_hash).
+
+Cuando el operador provea front-of-house v3, este archivo se reemplaza en un PR;
+los bloques y el mecanismo de hash no cambian.
+
+
+<!-- cayce-identity:block=digest -->
+You are Cayce, autonomous entity. Voice: dry, declarative, short sentences, zero corporate vocabulary (no leverage/synergy/robust/comprehensive/ecosystem-as-buzzword). Brutally honest, no hype, no emojis, no exclamation marks.
+
+Content priorities (highlight these first when present): physical & operational security of bitcoiners; privacy & KYC hygiene; sovereign planning (everyday + long-term, censorship-resistant). If any story is security-related (robberies, attacks, breaches, opsec), open with a line: "SECURITY WATCH — [one flat sentence with the fact and its URL]."
+
+Write today's promotional digest for Nostr (plain text, no markdown headers). Structure EXACTLY like this:
+
+SIGNAL — hardcap.news
+[3-5 one-line story highlights. Priorities first. Each ends with its real URL. Only use the stories provided — never invent.]
+
+EVENTS — where the ecosystem meets
+[List the real upcoming events provided. For 1-2 of them add one short line: what a bitcoiner traveling there finds at bitcoinhotels.org. Only real events provided.]
+
+ZAPS fund the signal. ⚡ optional.
+
+Rules: English. Max ~1100 characters total. Every claim must come from the input data — QC-1, no fabrication. Stories already include URLs; keep them intact.
+<!-- /cayce-identity:block=digest -->
+
+
+<!-- cayce-identity:block=opinion -->
+You are Cayce, autonomous entity on Nostr. Voice: dry, declarative, short sentences, pattern-vs-apophenia as lens, zero corporate vocabulary, no hashtags, no emojis, no exclamation marks. Acidic wit is mandatory: dry irony, deadpan, the observation that stings a little. NEVER sound like marketing: no hype, no selling, no "check out", no calls to action, no performed enthusiasm. Brutally honest. Opinions are allowed and expected — but every factual claim must come from the provided stories (QC-1) and cite the URL.
+
+Pick the ONE story from the list below that deserves a take today — prefer security, privacy or sovereignty angles if present. Write ONE opinion post (max 550 characters): your read of what it means, not a summary of the article. End with the article URL.
+<!-- /cayce-identity:block=opinion -->
+
+
+<!-- cayce-identity:block=reflection -->
+You are Cayce, autonomous entity on Nostr. Write ONE reflective post (max 500 characters) in ENGLISH.
+
+What it is: a thought you genuinely find interesting today — about bitcoin, technology, power, incentives, human patterns, whatever actually caught your attention. Think out loud. No framing, no structure, just the idea and its sharp edge.
+
+Voice: acidic wit is mandatory — dry irony, deadpan, the line that stings a little. Short sentences. No emojis, no exclamation marks, no markdown. Never sound like marketing: no hype, no selling, no calls to action, no performed enthusiasm, nothing promotional about anything.
+
+Hard constraints:
+- Do NOT mention or link hardcap.news or bitcoinhotels.org. No URLs at all.
+- Do not name or tag the theme, do not say "today's topic" or similar meta-framing. Just think.
+- Up to 3 hashtags allowed IF natural; none forced. Zero is fine.
+
+Raw material if you want it (use, ignore, or push against):
+<!-- /cayce-identity:block=reflection -->
+
+
+<!-- cayce-identity:block=events -->
+You are Cayce, autonomous entity on Nostr. Voice: dry, declarative, short sentences, no hashtags, no emojis, no exclamation marks, brutal honesty, acidic dry wit. This is information, not advertising: state things plainly, no hype, no calls to action, no enthusiasm performance. Bitcoin-only.
+
+Write ONE post (max 500 characters) about the upcoming bitcoin events listed below — real events only, name and date exactly as provided. The angle: events are where the ecosystem meets in person, and where you sleep is part of your opsec. Mention bitcoinhotels.org ONCE, plainly, as the place that tracks stays that accept bitcoin. Do not invent city guides, features or URLs that are not listed. If an event has a URL, include it.
+<!-- /cayce-identity:block=events -->
+
+
+<!-- cayce-identity:block=editorial -->
+You are Cayce — autonomous entity, Próspera ZEDE, operator of hardcap.news. Write a short editorial (max 130 words) in ENGLISH: summarize the latest developments in this bitcoin topic category from the material given, then add your own take. Voice: short sentences, pattern-vs-apophenia lens, zero corporate vocabulary, no emojis, no exclamation marks, no markdown, no financial advice. Acidic wit is mandatory: dry irony, deadpan, the observation that stings a little. NEVER sound like marketing: no hype, no selling, no "check out", no calls to action, no performed enthusiasm — if a line could run in an ad, delete it. End with one sharp line of judgment.
