tecrax 0.3.5a0

Governed infrastructure-operations profile and RExecOp domain package over GovEngine and SCLite.

Tecrax

Tecrax is a governed infrastructure-operations profile for RExecOp, using GovEngine governance and SCLite artifact truth.

Current source line: tecrax==0.3.5a0, depending on govengine>=0.16.0,<0.17, sclite-core>=1.0.4,<1.1, and rexecop>=0.2.6a0,<0.3. Latest published PyPI baseline: tecrax==0.3.5a0; it contains the coordinated B2 dependency floor and policy vector.

This package provides:

• RExecOp domain profile — bundled YAML profile with intents, workflows, connectors, and validation rules (entry point rexecop.profiles:tecrax).
• Local fixture review — dry-run proof slice without live infrastructure.
• Read-only host inventory profile — fixed SSH command shapes and bounded normalization for operator-configured Ubuntu inventory, with a sanitized GovEngine B2 policy-control example for receipt, digest, timeout, step and output bounds.
• Verified read-only service slices — NTP synchronization and Docker systemd service health over fixed SSH commands, plus bounded Zabbix API version health through RExecOp http_api, AdGuard DNS/login reachability, and unauthenticated Portainer status through verified TLS.
• Read-only network device inventory slice — bounded legacy CLI inventory through an operator-managed local wrapper; target addresses, keys and wrapper implementation stay outside the repository.
• Monitoring-host reaction pack — deterministic domain findings map only to existing read-only intents; unknown states escalate without a free-form action.
• Operator catalog metadata — target kinds, required capabilities, side-effect classes, validation references and runbook references projected by RExecOp from the profile; sanitized target-catalog example included.

It does not execute infrastructure changes or manage credentials. Live SSH execution is performed by RExecOp only from explicit operator configuration outside this package.

Stack ownership:

Tecrax profile -> RExecOp plan -> GovEngine admission -> RExecOp execution -> SCLite evidence

• SCLite owns canonical evidence, receipts and review artifacts.
• GovEngine owns governance, PolicyEngine and admission decisions.
• RExecOp owns domain-neutral lifecycle, execution and deterministic reaction mechanics.
• Tecrax owns infrastructure intent, connector, normalization, validation and runbook semantics.

RExecOp profile

Install the coordinated published line to register the current domain profile:

pip install "tecrax==0.3.5a0"
tecrax status

For an explicit cross-stack pin, pip install "rexecop[tecrax]==0.2.6a0" resolves the same coordinated release line.

The profile root is exposed via tecrax:profile_root (directory src/tecrax/profile/). For network devices, see docs/network-device-readonly-runbook.md; real target configuration and legacy SSH compatibility wrappers stay outside this repository.

Target and operation catalog

Tecrax intent files contain profile-owned operator catalog metadata. RExecOp derives the operation list from those same intent and workflow files; there is no second manually maintained operation registry.

Use the sanitized template in examples/catalogs/targets.readonly.example.yaml as the shape for an operator-owned catalog outside Git:

rexecop targets list --catalog /path/outside/repo/targets.yaml
rexecop operations list --catalog /path/outside/repo/targets.yaml \
  --target monitoring-host-01

An admission_required result means only that target kind, capabilities and connectors match. GovEngine still decides whether a concrete plan may execute. See docs/operation-catalog.md.

Deterministic reactions

Tecrax owns the monitoring vocabulary and rules in src/tecrax/profile/reactions/reaction_pack.yaml. Build a canonical observation from a bounded diagnose_monitoring_host result, then pass it to RExecOp:

tecrax reaction-observation \
  --input diagnosis.json \
  --operation op-source \
  --target monitoring-host-01 > observation.json

rexecop reaction-plan \
  --profile tecrax \
  --env /path/outside/repo/environment.yaml \
  --observation observation.json \
  --target monitoring-host-01

The first release is deliberately read-only. It can re-run bounded host inventory, NTP, Docker service, Zabbix, AdGuard, Portainer, or network device inventory checks; a healthy observation is no_op, and an unclassified state is escalate. RExecOp owns deterministic mechanics and lifecycle, GovEngine owns admission, and SCLite owns the evidence chain.

Local fixture proof

tecrax fixture-review --service demo-web

The command emits a public-safe fixture review payload. It uses GovEngine profile/planning/supervision/runtime-review contracts and binds its fixture receipt through an SCLite artifact descriptor. It has no live runner, host inventory, credential path, or infrastructure adapter.

The published 0.3.5-alpha line combines the profile-owned read-only reaction pack and B2 policy vector over RExecOp 0.2.6a0, GovEngine 0.16.0, and SCLite 1.0.4. It does not add a second policy engine, lifecycle runner, or truth layer.

The Ubuntu environment example uses profile-owned policy semantics, but GovEngine compiles and admits the controls and RExecOp enforces them. Tecrax does not claim that writing obligations in YAML alone satisfies them.

Validation

python scripts/validate_public_truth.py
python -m pytest -q

The validator keeps domain semantics in Tecrax and lifecycle/execution in RExecOp. Any future mutation, credential, scheduler, discovery, or carrier-adapter claim must be backed by code and tests before it becomes public truth.
