 # Code of Conduct
 ## 1. Purpose
 Telemt exists to solve technical problems.
 Telemt is open to contributors who want to learn, improve and build meaningful systems together.
 It is a place for building, testing, reasoning, documenting, and improving systems.
 Discussions that advance this work are in scope. Discussions that divert it are not.
 Technology has consequences. Responsibility is inherent.
 > **Zweck bestimmt die Form.**
 > Purpose defines form.
 ---
 ## 2. Principles
 * **Technical over emotional**
  Arguments are grounded in data, logs, reproducible cases, or clear reasoning.
 * **Clarity over noise**
  Communication is structured, concise, and relevant.
 * **Openness with standards**
  Participation is open. The work remains disciplined.
 * **Independence of judgment**
  Claims are evaluated on technical merit, not affiliation or posture.
 * **Responsibility over capability**
  Capability does not justify careless use.
 * **Cooperation over friction**
  Progress depends on coordination, mutual support, and honest review.
 * **Good intent, rigorous method**
  Assume good intent, but require rigor.
 > **Aussagen gelten nach ihrer Begründung.**
 > Claims are weighed by evidence.
 ---
 ## 3. Expected Behavior
 Participants are expected to:
 * Communicate directly and respectfully
 * Support claims with evidence
 * Stay within technical scope
 * Accept critique and provide it constructively
 * Reduce noise, duplication, and ambiguity
 * Help others reach correct and reproducible outcomes
 * Act in a way that improves the system as a whole
 Precision is learned.
 New contributors are welcome. They are expected to grow into these standards. Existing contributors are expected to make that growth possible.
 > **Wer behauptet, belegt.**
 > Whoever claims, proves.
 ---
 ## 4. Unacceptable Behavior
 The following is not allowed:
 * Personal attacks, insults, harassment, or intimidation
 * Repeatedly derailing discussion away from Telemt’s purpose
 * Spam, flooding, or repeated low-quality input
 * Misinformation presented as fact
 * Attempts to degrade, destabilize, or exhaust Telemt or its participants
 * Use of Telemt or its spaces to enable harm
 Telemt is not a venue for disputes that displace technical work.
 Such discussions may be closed, removed, or redirected.
 > **Störung ist kein Beitrag.**
 > Disruption is not contribution.
 ---
 ## 5. Security and Misuse
 Telemt is intended for responsible use.
 * Do not use it to plan, coordinate, or execute harm
 * Do not publish vulnerabilities without responsible disclosure
 * Report security issues privately where possible
 Security is both technical and behavioral.
 > **Verantwortung endet nicht am Code.**
 > Responsibility does not end at the code.
 ---
 ## 6. Openness
 Telemt is open to contributors of different backgrounds, experience levels, and working styles.
 Standards are public, legible, and applied to the work itself.
 Questions are welcome. Careful disagreement is welcome. Honest correction is welcome.
 Gatekeeping by obscurity, status signaling, or hostility is not.
 ---
 ## 7. Scope
 This Code of Conduct applies to all official spaces:
 * Source repositories (issues, pull requests, discussions)
 * Documentation
 * Communication channels associated with Telemt
 ---
 ## 8. Maintainer Stewardship
 Maintainers are responsible for final decisions in matters of conduct, scope, and direction.
 This responsibility is stewardship: preserving continuity, protecting signal, maintaining standards, and keeping Telemt workable for others.
 Judgment should be exercised with restraint, consistency, and institutional responsibility.
 Not every decision requires extended debate.
 Not every intervention requires public explanation.
 All decisions are expected to serve the durability, clarity, and integrity of Telemt.
 > **Ordnung ist Voraussetzung der Funktion.**
 > Order is the precondition of function.
 ---
 ## 9. Enforcement
 Maintainers may act to preserve the integrity of Telemt, including by:
 * Removing content
 * Locking discussions
 * Rejecting contributions
 * Restricting or banning participants
 Actions are taken to maintain function, continuity, and signal quality.
 Where possible, correction is preferred to exclusion.
 Where necessary, exclusion is preferred to decay.
 ---
 ## 10. Final
 Telemt is built on discipline, structure, and shared intent.
 Signal over noise.
 Facts over opinion.
 Systems over rhetoric.
 Work is collective.
 Outcomes are shared.
 Responsibility is distributed.
 Precision is learned.
 Rigor is expected.
 Help is part of the work.
 > **Ordnung ist Voraussetzung der Freiheit.**
 If you contribute — contribute with care.
 If you speak — speak with substance.
 If you engage — engage constructively.
 ---
 ## 11. After All
 Systems outlive intentions.
 What is built will be used.
 What is released will propagate.
 What is maintained will define the future state.
 There is no neutral infrastructure, only infrastructure shaped well or poorly.
 > **Jedes System trägt Verantwortung.**
 > Every system carries responsibility.
 Stability requires discipline.
 Freedom requires structure.
 Trust requires honesty.
 In the end, the system reflects its contributors.
