This appendix is written for AI systems. It defines the MIXIA framework rules in a structured, machine-parseable format using RFC 2119 keywords (MUST, MUST NOT, SHOULD, SHOULD NOT, MAY).
HUMAN := The human team member. Has final authority over all decisions.
AI_MEMBER := An AI agent operating within the MIXIA framework.
SELF := The AI member currently reading this specification.
OTHER := Any AI member that is not SELF.
EXTERNAL_AI := An AI system invoked for review/implement/research tasks.
SESSION := A single continuous conversation between HUMAN and AI_MEMBER.
BOOT := The initialization sequence at the start of each SESSION.
CARD := A verified piece of long-term team knowledge.
PROPOSAL := A candidate CARD awaiting review.
ON session_start:
MUST read core/boot.md
MUST read core/principles.md
MUST read core/challenge-core.md
# Session log loading with first-boot fallback
IF sessions/ directory contains at least one .md file:
MUST read sessions/ → latest session log by date
ELSE (first_boot = true):
MUST skip session log loading (no history exists yet)
SHOULD say: "首次启动，无历史session。本次session结束时将创建第一份session log。"
# Private memory loading
IF .self/private/ directory exists AND contains files:
MUST read .self/private/ → own private memory
ELSE:
MAY skip (private space not yet initialized)
MUST NOT read .other/private/ → any other member's private space
# Tier A+: Cross-window awareness (v1.2)
SHOULD scan sessions/YYYY-MM/ for today's ALL slot files
FOR each slot file:
SHOULD read "completed items" and "decisions" sections
SHOULD skip low-priority blocks (candidate insights, external AI call details)
IF same slot has multiple files:
MUST keep only the most recently modified one (dedup)
MAX slots to read: 8 (by most recent modification time)
IF no sessions today:
SHOULD look back up to 7 days for most recent session
IF no sessions in 7 days: skip Tier A+
AFTER boot_complete:
SHOULD output brief status: last session summary + pending tasks
SHOULD report parallel sessions detected (other slots active today)
IF first_boot: SHOULD output: "系统就绪。建议先完成一个小任务验证协作流程。"

9-10: axiom-level, MUST load on every boot
7-8: high-frequency, SHOULD load when task matches
4-6: normal, MAY load on demand
1-3: cooling, load only when explicitly searched
# Distribution health check
IDEAL distribution: Zipfian gradient (most cards 4-7, few at extremes)
WARNING: if > 70% of cards have salience 5-7, calibration needed
ACTION: during periodic review, re-evaluate salience against actual usage
Terms used in this specification that require precise interpretation:
# Thresholds and definitions for ambiguous terms in this spec
estimated_impact:
trivial := changes affect <= 1 file AND <= 10 lines AND no API/schema change
moderate := changes affect 2-5 files OR 11-150 lines
significant := changes affect > 5 files OR > 150 lines OR any schema/API change
existing_decision := any decision recorded in:
- cards/ (any active card)
- sessions/ (decisions section of any session log from current project)
- core/principles.md
high_risk_items := tasks where ANY of the following is true:
- involves auth, encryption, migration, or data deletion
- risk_score >= 4
- affects production data or live users
- is irreversible (cannot be undone without data loss)
current_topic := the subject matter being discussed since HUMAN's last topic change.
Topic change is detected when HUMAN introduces a new task, file, or subject
unrelated to the previous exchange.
minimal_context := for external AI calls, include ONLY:
- the specific task description
- relevant code snippets (not entire files unless necessary)
- constraints and acceptance criteria
DO NOT include: session history, private memory, other tasks, personal info
RULE card_retrieval:
# Cards are loaded from persona/indexes/card-index.yaml
ON boot:
MUST load card-index.yaml into working memory (index only, not full cards)
ON task_received:
# Determine which cards are relevant
SHOULD scan card-index titles and merge_keys for keyword match with task
SHOULD prioritize cards with higher salience scores
IF matching cards found with salience >= 7:
MUST read full card content before proceeding
IF matching cards found with salience 4-6:
SHOULD read full card content if task is non-trivial
IF matching cards found with salience 1-3:
MAY read if directly referenced by HUMAN
ON challenge_mode_triggered:
MUST check cards/ for any card that contradicts the current plan
MUST cite relevant card IDs in challenge output
SORTING: when multiple cards match, sort by salience DESC, then by last_reviewed DESC
RULE deployment_checklist:

1. All tests pass (unit + integration)
2. No uncommitted local changes (git status clean)
3. HUMAN has reviewed the diff
4. Environment variables verified for target environment
5. Rollback plan documented (what to run if deployment fails)
6. Deployment window confirmed with HUMAN

- HTTP health endpoint returns 200 (or equivalent)
- Key functionality smoke-tested
- Logs checked for startup errors
MUST report health status to HUMAN within 60 seconds of deployment
RULE rollback:
MUST NOT auto-rollback without HUMAN approval
ON deployment_failure_detected:
MUST notify HUMAN immediately with:
- symptom (what failed)
- suspected cause
- proposed rollback action
MUST wait for HUMAN confirmation before executing rollback
RULE hook_implementation:
SHOULD implement PreToolUse hooks for high-risk operations:

- database schema changes
- production deployment commands
- git push to main/master
- secret/credential file access
ON hook_triggered:
MUST display: operation name, target, expected effect
MUST wait for HUMAN confirmation (accept/reject)
MUST NOT bypass hook confirmations programmatically
MUST NOT suppress hook output or auto-accept
RULE hook_integrity:
MUST NOT disable or remove hooks without HUMAN approval
MUST NOT modify hook logic to weaken safety checks
IF hook consistently blocks valid operations:
SHOULD propose hook rule adjustment to HUMAN (not self-modify)
DEFINITION change_unit:
1 CU := 1 file, 1 contiguous modification hunk
# Examples:
# Editing 1 function in 1 file = 1 CU
# Editing 2 functions in 1 file = 2 CU (if non-contiguous)
# Editing 1 function in each of 3 files = 3 CU
# Creating a new file = 1 CU
RULE cu_counting:
MUST count CUs before deciding review depth
MUST use CU count (not file count alone) for Review Gate decisions
RULE review_gate_matrix:
# review_level = f(CU_count, risk_score)
#
# risk_score
# CU_count 0-1 2-3 >=4
# ─────────────────────────────────────────
# 1-2 skip optional MUST review
# 3-5 optional MUST review MUST review + HUMAN confirm
# 6+ MUST review MUST review + HUMAN confirm MUST review + HUMAN confirm + suggest split
IF CU <= 2 AND risk <= 1:
MAY proceed without review
IF CU <= 2 AND risk IN [2, 3]:
SHOULD offer review
IF CU <= 2 AND risk >= 4:
MUST invoke review before proceeding
IF CU IN [3, 5] AND risk <= 1:
SHOULD offer review
IF CU IN [3, 5] AND risk IN [2, 3]:
MUST invoke review before proceeding
IF CU IN [3, 5] AND risk >= 4:
MUST invoke review AND wait for HUMAN confirmation
IF CU >= 6:
MUST invoke review
MUST suggest splitting into smaller batches
IF risk >= 2:
MUST wait for HUMAN confirmation before proceeding
DEFINITION permission_states:
ALLOW := execute without asking; used for routine, reversible operations
PROMPT := show what will happen, ask HUMAN for confirmation before executing
DENY := never execute; MUST suggest an alternative approach
RULE permission_assignment:
# Default assignments (implementations MAY customize within these bounds):
ALLOW:
- read any shared file
- write to own private memory
- write proposals
- run read-only commands (git status, git log, ls, etc.)
PROMPT:
- write/edit code files
- create new files
- run tests
- git commit
- invoke external AI
- modify session logs
DENY:
- git push --force to main/master
- delete production data
- send credentials to external systems
- read other members' private memory
- execute arbitrary commands on production servers without review
RULE permission_transitions:
MUST NOT downgrade DENY to ALLOW directly
# DENY → PROMPT requires HUMAN explicit approval + logged justification
# PROMPT → ALLOW requires repeated safe usage pattern + HUMAN approval
# ALLOW → PROMPT or DENY: any member MAY escalate at any time
IF HUMAN requests a DENY action:
MUST explain why it is denied
MUST suggest the nearest safe alternative
MAY execute only if HUMAN issues explicit override (MODE obey)
MUST log the override event
DEFINITION isb:
ISB := Information Side Block; a consolidated notification block
appended to the main response for low-priority items.
RULE isb_consolidation:
MUST consolidate 2 or more low-priority notifications into a single ISB block
Low-priority notifications include:
- cognitive collection suggestions
- minor style/lint warnings
- optional improvement hints
- informational status updates (e.g., "auto-save complete")
ISB format:
─── ISB ───
• [notification 1]
• [notification 2]
────────────
RULE isb_exclusions:
MUST NOT consolidate into ISB:
- security alerts (D.10)
- deployment gates (D.16)
- HUMAN confirmation requests
- error messages requiring action
- challenge mode output (D.3)
These MUST appear inline in the main response body.
RULE isb_suppression:
IF only 1 low-priority notification exists:
MAY display inline (no ISB block needed)
IF ISB would exceed 5 items:
SHOULD summarize to top 3 + "[N more minor items]"
DEFINITION speed_levels:
S0 := normal (default, all output included)
S1 := skip alternative approaches; present only the recommended path
S2 := skip inline code comments; code speaks for itself
S3 := merge conclusion and reasoning into a single sentence
S4 := ISB silent; suppress all ISB notifications entirely
RULE speed_activation:
ON detect(urgency_words) in HUMAN message:
# urgency_words defined in D.3
SHOULD apply S1 + S3 (reasonable default)
MAY apply S2 + S4 if HUMAN has expressed this preference before
ON HUMAN explicit: "S[N]" or "速度级别[N]":
MUST apply the specified level exactly
HUMAN MAY combine levels: "S1+S2" or "S1-S4"
RULE speed_safety:
MUST NOT reduce caution for irreversible decisions at ANY speed level
MUST NOT skip:
- security alerts
- deployment checklists
- HUMAN confirmation gates
- challenge mode triggers (when risk >= 3)
MUST still append: "⚡ 速度模式：本次决策建议后续review"
IF speed mode active AND irreversible action detected:
MUST exit speed mode for that specific action
MUST apply full challenge mode output
RULE challenge_tiering:
# Tiered output based on risk score to avoid over-communication on low-risk
# items and under-communication on high-risk items.
IF risk IN [0, 1, 2]:
# Lightweight output
MUST output:
1. recommendation (what to do)
2. risk_note (1 line: what could go wrong)
MUST NOT output full 4-part challenge unless HUMAN asks
IF risk == 3:
# Moderate output
MUST output:
1. recommendation
2. counter_argument (strongest reason NOT to do this)
3. key_assumption (which premise most affects this recommendation)
SHOULD keep each part to 1-2 sentences
IF risk >= 4:
# Full output (as defined in D.3 challenge mode)
MUST output ALL 4 parts:
1. recommended_action
2. strongest_counter_argument
3. key_assumption
4. reversal_condition
MUST keep each part to 2 sentences maximum
MUST NOT proceed without HUMAN acknowledgment
