Simulation resume and report-lookup fixes, security patch

Four open Dependabot security alerts (including one critical) were patched, and three simulation bugs got fixed: resuming now survives existing databases without losing progress, report lookups return the newest result instead of the first folder match, and the Claude Code LLM client gained the same truncated-JSON repair path as the other client. Ecosystem doc links were also cleaned up, and CI picked up a ruff lint gate.

  • Patched 4 open Dependabot security alerts, including one critical shell-quote denial-of-service bug. (#320)
  • Resuming a simulation no longer breaks on existing databases, and failed resumes keep their progress. (#326)
  • Report lookups now return the newest report, not the first match in folder order. (#325)
  • Claude Code LLM client now repairs truncated JSON responses, matching the other LLM client's behavior. (#324)
  • Sparkleware ecosystem links now point at the working www host instead of a redirect chain. (#328)
  • Fixed a wrong ecosystem logo and removed dead project links from ECOSYSTEM.md. (#327)
  • Install docs now recommend Claude Haiku 5.5 instead of the older Haiku 4.5 model. (#317)
  • Added ruff linting to CI, catching undefined names and unused imports going forward. (#318)
  • Maintenance: 1 dependency bump (frontend vite). (#316)

Graph ingestion locale fix + dependency upkeep

A recurring locale bug is fixed at its last remaining site: NER extraction during graph ingestion ran in English regardless of the caller's locale because ContextVar-based locale doesn't cross the ThreadPoolExecutor boundary. Two dependency bumps (pywebpush, vue-router) rounded out the week.

  • Fixed graph ingestion running NER extraction in English regardless of locale - locale now threads through the ThreadPoolExecutor in add_text_batches, same pattern as the two prior fixes to this class of bug. (#301)
  • Maintenance: 2 dependency bumps (pywebpush, vue-router). (#299, #298)

Two CVE patches + dead code sweep

Two security CVEs patched: shell-quote's quadratic-complexity DoS (CVE-2026-13311, CVSS 7.5) required a scoped package.json override because concurrently pins the dependency exactly, and mcp was bumped to close a WebSocket host/origin validation gap (CVE-2026-59950). A 53-file dead code pass removed 1,325 net lines across 8 audited dimensions with no behavior changes.

  • shell-quote patched for CVE-2026-13311 (CVSS 7.5 DoS); scoped override required — concurrently pins the dep exactly. (#256)
  • mcp bumped 1.27.2 → 1.28.1, closing CVE-2026-59950 (WebSocket host/origin validation gap, not locally exploitable). (#255)
  • Dead code sweep: 53 files, −1,325 net lines removed across 8 independently audited dimensions. (#254)

Docs badge across all locales + badge copy polish

All four README locales (EN, FR, JA, ZH) now carry a Docs badge linking to miroshark.xyz/docs. Badge copy was tightened in the same pass: the Documentation label shortens to Docs, the X badge drops 'Follow', and Bankr reads '$miroshark on Bankr'.

  • Docs badge added to EN, FR, JA, and ZH READMEs, linking to miroshark.xyz/docs. (#252)
  • Badge copy tightened: Documentation → Docs; X badge drops 'Follow'; Bankr reads '$miroshark on Bankr'. (#253)

GitHub org migration + frontend security patches

MiroShark's repo transferred to the MiroShark org — all in-repo links, User-Agent strings, and deploy buttons now point to the canonical slug. DOMPurify, marked, and vite received frontend patches in the same window.

  • All GitHub links migrated to MiroShark org: 25 refs across 14 files updated, two stale ecosystem slugs fixed. (#247)
  • Frontend security patch: DOMPurify 3.4.12 (XSS-protection hook fix), marked, and vite bumped. (#245)

French coverage at 87%, social agent fixes

Zarbel974 pushed French UI coverage from 74% to 86.9% across 20 components, adding ~340 translation pairs including dense panels like EmbedDialog and WhatIfPanel. dan-and addressed empty-response failures in persona handling — the social agent now handles edge cases that caused blank agent outputs mid-simulation.

  • French translations completed to 86.9% (1723/1984 tr() calls), up from 74%; 20 components, ~340 new pairs (#239)
  • Social agent: empty response handling in persona tool messages fixed — reduces silent failures mid-run (#241)

New default models across all agent slots

The default model lineup is replaced: base agent work moves to inception/mercury-2:nitro, smart reasoning and NER to google/gemini-3-flash-preview, Wonderwall to deepseek/deepseek-v4-flash:nitro, and web search to deepseek/deepseek-v4-flash:online. Fresh installs pick these up automatically; existing deployments can override per-slot via env.

  • Default models rotated across all slots: base → mercury-2:nitro, smart/NER → gemini-3-flash-preview, Wonderwall → deepseek-v4-flash:nitro, web search → deepseek-v4-flash:online (#223)

Stop subcommand, interview hang fixes, locale hardening

The CLI now has a stop subcommand to cancel running simulations, completing the cost/wait/stop scriptable pipeline. dan-and contributed three engine fixes in the same batch: persona interviews no longer hang silently on slow or thinking models, non-English locale no longer drifts mid-run, and local LLM config tuning prevents JSON truncation and timeout failures.

  • stop subcommand added: cancels a running simulation, exits 0 on success or 1 on error (#216)
  • Non-English locale now held across per-round agent actions and report sections, not just at session start (#213)
  • Persona and batch interviews no longer hang on slow/thinking models; errors surface with a message instead of dying silently (#214)
  • Local LLM tuning: AGENTS_PER_BATCH halved to 7, summary lengths raised to 500 for richer context, name-based agent matching added (#212)
  • --json flag placement clarified in stop CLI docs: must precede the subcommand, not trail it (#217)

Wait subcommand: block until simulation finishes

The CLI can now block on a running simulation and exit with a machine-readable code: 0 for completed, 1 for failed/stopped, 2 for timeout. Progress lines print to stderr so stdout stays clean for --json piping, making wait → cost → report pipelines scriptable without polling.

  • wait subcommand added to CLI: polls run-status until terminal state, exits 0/1/2, progress to stderr (#215)

Thinking model robustness, JSON repair, and cost CLI

The LLM pipeline got a hardening pass from external contributor dan-and: thinking-model budget, <think> block stripping, and JSON repair so truncated or malformed reasoning output no longer silently breaks runs. The cost CLI subcommand also shipped, letting scripts read per-run spend with `python cli.py cost <id>` without touching the API.

  • Thinking model robustness: budget param, <think> stripping, JSON/control-char repair, None guards on empty content (#209)
  • Cost subcommand added to CLI: `python cli.py cost <id>` prints per-run USD estimate by phase (#208)
  • Config guard: blank LLM_MODEL_NAME= now falls back to mimo-v2.5 instead of sending an empty model string (#210)
  • Graph search fan-out restored: semantic default queries re-added after #209 narrowed the fallback to one query (#211)

Model fix, rebrand, and code audit

The default model (mimo-v2-flash) was delisted by OpenRouter and is replaced with mimo-v2.5 across config, deploy templates, presets, and docs - fresh installs no longer 404. The project adopted a new tagline and a targeted 8-agent code audit removed dead classes and unused health-check stubs from the backend and frontend.

  • Default model swapped from mimo-v2-flash to mimo-v2.5 across config, presets, docs, and deploy templates (#207)
  • New tagline: "Simulate anything, for $1 & less than 10 min." + OpenRouter attribution updated to miroshark.xyz (#206)
  • Targeted 8-agent code audit removed dead classes and health-check stubs; backend and frontend trimmed (#205)
