Giorgio Gilestro 2f223b75a3 strip prompt-echo leakage in indicator summaries 
DeepSeek occasionally regurgitates the system prompt verbatim
("Constraints: ≤60 words...", "Example good: ..."). Three-pronged fix:

1. Removed the inline good/bad example blocks from the per-group and
   aggregate system prompts — DeepSeek was treating them as templates
   to copy. The hard constraints alone are clear enough.

2. Expanded the LEAK_PATTERNS list to catch the prompt-label echoes
   that still occasionally slip through ("Key observations:", "The
   indicators are:", "Must cite ...", "Should give ...", bare "Key:").
   Cleanup now runs up to 6 passes for compound leakage.

3. Added looks_like_leakage() — if the cleaned output still contains
   tell-tale phrases ("≤60 words", "instructions:", etc.), the summary
   is skipped rather than persisted. Logs a 'leakage_detected' warning
   and an ai_calls row with status=leaked so we can see the failure
   rate over time. The previous good summary stays visible.

Cassandra

Containerised macro-strategy dashboard — hourly market data, RSS news, Trading 212 portfolio, and an AI-generated strategic log. Read-only by design.

Quick start

cp .env.example .env       # fill in API keys; set CASSANDRA_TOKEN if exposing
docker compose up --build  # db + app + scheduler + daily backup sidecar
open http://localhost:8000/

Architecture

  • app (FastAPI + Jinja2 + HTMX) — web dashboard on port 8000
  • scheduler (APScheduler) — hourly ingestion jobs (market, news, portfolio, AI log)
  • db (MariaDB 11) — quotes, headlines, portfolio snapshots, strategic logs, job runs
  • backup (sidecar) — daily mariadb-dump to ./backup/

See /home/gg/.claude/plans/ok-i-think-this-tidy-lake.md for the design plan.

Config

File Purpose
config/default.toml Universal data tables: indicator groups, RSS feeds, keyword presets
config/portfolio.toml User-specific portfolios (overrides default.toml)
.env Secrets and runtime knobs — mounted read-only into containers

Endpoints

  • GET / — dashboard
  • GET /portfolio/{name} — portfolio detail
  • GET /news — news feed
  • GET /log — strategic-log archive
  • GET /api/health — job status (last success / failure per job)

All authenticated routes require Authorization: Bearer $CASSANDRA_TOKEN if the env is set; if unset, the app is open (LAN-only mode).
