  "textContent": "Lot of chatter on the interwebs lately about _\"state surveillance\"_ , where _\"both sides\"_ are relentlessly attempting to remove all **_E_** nd-to-**_E_** nd-**_E_** ncyption _(aka**E2EE**)_, but that is not what this post is about, and this post is not about politics.\n\nAlso a lot of talk about Github being compromised and having 3,000+ internal repos exfiltrated. Surely GitHub has 100% Code Coverage Testing and End-to-End Test (Work)Flows, right? No, they do not. Anyway..\n\nThis post is focused on **E2ET** _(**_E_** nd-to-**_E_** nd-**_T_** esting) _of application service roles and machine provisioning automation. So, let's start by seeing just exactly wtf I'm referring to with testing in the first place.\n\n* * *\n\n## CI Systems - Failure Mode Example\n\nIn the reporting system here we use a host type definition of `K10` which is mostly arbitrary, but the root story is an irrelevant tangent, used in this infrastructure as an example of a standdalone system which requires specific attention to failure state definitions, stateful analysis of gated operations, and is used for iterative looped-based resolution testing.\n\nThe **K10** host is assigned to a role which features CPU-native `cpuid2cpuflags` architecture optimized compiler flags. We never use generic kernels, or generic machines, because efficiency and optimization in the industry is basically a broken afterthought and it gets old after a while - dealing with non-optimized non-attentitive systems engineering approaches featuring inefficient broken theories based the shrug-method, _\"just make it auto-scaling and put more kubes or something?\"_\n\n* * *\n\n### Network Booting the Baseline OS\n\nThe **K10** baseline system boots over the network using `iPXE/HTTPv4,` while other devices require `chainload PXE/TFTP -> iPXE/HTTPv4` boot images. This facilitate a system of host-based discovery and domain authentication via `initrd` embedded kernel modules + connection parameters for `FreeIPA/SSSD for RBAC + AAA` using MAC and PKE enrollment. We also do this for FreeBSD hosts, with some minor differences.\n\nThe **K10** is also connected to local-rack PDUs with remote power cycling via either `ACPI signal` for _\"soft shutdown\"_ or via its switched-outlet port. The PDUs are controlled by the Command-&-Control Server using `SNMPv3 user + group authentication` via its infrastrcture management LAN connection with an auth-hook to FreeIPA via RADIUS.\n\n### Let's See Some Reports!\n\nHaving covered some blathering about provisioning systems, we can move on to agent-based querying for `SITREP` , which is executed on our in-house LLM structured query execution tooling. That whole chain of events required writing a new _\"Agentic Forge Control Plane\"_ , which was enjoyable most of the time... and it has become a baseline distributed comms system for \"Project Coherent Storage\" which is currently managing a bit over 1PB of data on OpenZFS.\n\nEarlier this year I paused for some PTO and rewrote all of my formerly Ansible driven and automated `Infrastructure as Code` workflows to support an upcoming revision to our dual-continent presence at six datacenter locations. It's occasionally and very tentatively being referred to as `\"minimalist-maxxing\"` which is mostly pure nonsense where grammatical excellence is concerned, but ultimately accomplishes the following:\n\n  * Gentoo w/ Optimized Stage4, LLVM/Clang, OpenRC\n  * Minimalist service containers using our Stage4 baseline, with service roles layered on top. Try it out:\n\n\n\nNo, these were not Kubernetes, not Helm, not Cloudslop. Sometimes translates into `Infrastructure as a Service`, for enablement of `event-driven architecture` with a hybrid-local service enablement for LLM predictive action controls.\n\nThat's a lot of words to say, _\"I make the code do the things with the signals processing and patterns and stuff.\"_ Wait wait.. no, this is not going to cover anything about _\"N~less Computing\"._\n\nstop calling anything _\"Serverless Computing\"_ or _\"Whatever-less Barf\"_.\n\n> [host K**10**]: currently has transient AAA validation, not E2ET pass. The AP7901 reboot proved the current netboot rootfs does not persist SSSD/IPA state.\n>\n> Under this definition, **K10** must rebuild rootfs or disk-install with aaa-domain-client, reboot, then pass the full post-boot E2ET suite before it can unblock `xen-sun99-x12spl-099108.rfc1918.host` reimage confidence.\n\n### Standard Example 'K10 Automation Report'\n\n\n    # E2ET Definition\n    End to End Testing / E2ET should mean: a reproducible host acceptance pipeline that proves a machine can move from inventory intent to installed, rebooted, validated, scored, documented, and release-eligible state.\n\n    For RFC99, a host is not E2ET-passed just because we fixed it live. It passes only after the fix is represented in source-of-truth and survives the full lifecycle.\n\n    ## Policy Definition\n    For validation hosts like `K10`:\n\n    1. Fix live only to recover evidence or confirm root cause.\n    2. Backport the fix into repo-owned profile, role, manifest, package list, NetBox/DNS/IPAM metadata, and docs.\n    3. Reinstall or rebuild/reboot through the intended provisioning path.\n    4. Run post-boot validation.\n    5. Generate a conformance report.\n    6. Only then mark the host RC/GA-capable.\n\n    > A one-off live fix can be marked transient validated, but never E2ET passed.\n\n    ## E2ET Stages\n\n    ### Host Pipeline\n\n    1. **Inventory Gate**: NetBox/IPAM/DNS/Ansible host metadata matches expected MACs, interfaces, service IPs, PDU mapping, console path, boot protocol.\n    2.** Provisioning Gate**: iPXE or PXE-chainload path works, installer runs, ZFSBootMenu/bootfs/rootfs pools validate, OS install completes.\n    3. **First Boot Gate**: kernel cmdline, serial console, hostname/FQDN, SSH, time sync, logging, package profile, OpenRC services.\n    4. **Platform Gate**: CPU model, RAM, disks, NVDIMM/Optane if present, sysfs, kernel modules, firmware, CVE mitigation status.\n    5. **Network Gate**: management interface, service interfaces, VLANs, routes, DNS forward/reverse, NetBox consistency, nmap readiness.\n    6. **Storage Gate**: ZFS pools, NFSv3/v4, NFS-RDMA, Ceph, iSER, iSCSI, sshfs as applicable.\n    7. **Identity Gate**: FreeIPA/SSSD/PAM/SSH keys, UID/GID consistency, sudo policy, offline cache, break-glass account.\n    8. **Service Gate**: required services running, no unexpected failed services, role-specific smoke/functional checks.\n    9. **Performance Gate**: CPU, memory, disk, network, build/distributed compile benchmarks against baseline.\n    10. **Conformance Report**: JSON + Markdown + optional JUnit output with hard-gate pass/fail and weighted score.\n\n    ### Scoring Model\n    Use hard gates plus weighted scoring.\n\n    ### Hard Fails\n      - Cannot boot.\n      - Cannot SSH via management path.\n      - IPAM/DNS mismatch for primary identity.\n      - Root pool invalid.\n      - SSSD missing on an AAA-required profile.\n      - Required service failed.\n\n    ### Score Zones\n      - p60: minimally usable, not release candidate.\n      - p80: acceptable lab host.\n      - p90: RC candidate.\n      - p95: GA for normal infra.\n      - p99: production-critical or rebuild-template quality.\n\n    ## Policyinctions\n    While there is overlap with \"conformance tiers\", this functionally is separate from \"statistical confidence\" until we have sufficient historical run-data to compute \"Real-Number Percentiles\" and data-driven pattern-based repeatably-provable \"Statistically Significant\" probability assessments.\n\n    ### K10 Applied Meaning\n    The host definition for `K10` currently has transient AAA (not AAA DNS: `\"ACK & AGREE & APPROVE\"`) validation, not E2ET pass.\n\n    #### **Actioned Event**\n    Its connected PDU port *(SKU: APC AP7901)* reboot proved the current `netboot rootfs` does not persist `SSSD/IPA` state.\n\n    #### **Action Rephase**\n    Host definition `K10` requires a rebuild of rootfs or disk-install with `aaa-domain-client`, another reboot, then pass the full `Post-Boot E2ET` test suite before it can unblock dependency-trees.\n\n    Otherwise K10 risks being labeled a permanent `reimage-processing confidence blocker`, which leads to hardware decomission.\n\n    ## K10 Dead-Reckoning\n    Previously we defined the `RFC99` & `SUN99` workflow as `K10 Host E2ET Acceptance Pipeline v0.1`, for this we'll re-implement the process using block-notation in Ansible + Python with the new report tooling, and enable `cicd-rfc99-jenkins-099199` for orchestrating it once the checks are stable.\n",
