# Two pipelines in one file, split by event (Woodpecker, NEVER GitHub Actions):
#
#   • event: push  → the m11p8 RELEASE GATE (rolling-upgrade tier-3 test) then a
#     Kaniko image build. Deployment is MANUAL (kustomize, orchard9-k3sf ops repo).
#   • event: cron  → the m11p9 NIGHTLY CONTINUOUS-CORRECTNESS run: the tier-3
#     chaos suites (incl. the disk-full / slow-fsync / asymmetric-partition fault
#     classes) with elevated kill-points, plus the security/ops owner-tests (mTLS,
#     backup/restore round-trip, gap-free WAL archival). A nightly failure flags a
#     correctness regression for that day.
#
# Per-step `when:` routes each step to its event; the workflow-level `when` admits
# both. The cron pipeline requires a cron named "nightly" in the Woodpecker repo
# settings (the same `tidal-server` binary serves standalone AND multi-process
# `cluster --region`, so one image covers both deployments).
#
# ── Honesty note, 2026-08-30 ────────────────────────────────────────────────────
# For 216 days this file described a nightly correctness programme that had NEVER
# RUN: the "nightly" cron was never created, so four pipelines existed in total
# and all were push events. Tier-3 chaos, the fault classes, the soak's p99 and
# error-rate gates, mTLS and the PITR test produced exactly ZERO signal, while
# reading to anyone opening this file like rigorous standing coverage. A gate
# nobody runs is worse than no gate, because it makes the project look covered.
#
# The nightly SOAK step was REMOVED rather than scheduled. It is not a capacity
# quibble — it is unfalsifiable here. Measured free capacity on the best node is
# 1700m CPU (agent-1; server-1/2 have 435m/550m), and the step drove 1000 rps for
# 600s while gating on p99 ≤ 250ms. On that hardware the gate fails from CPU
# starvation, not from a regression, so scheduling it would manufacture a nightly
# false alarm — the same fake-coverage defect inverted. Its command list now lives
# in docs/runbooks/nightly-soak.md as a pre-release step, run where the capacity
# to make its numbers mean something actually exists.
when:
  branch: main
  event: [push, cron]

# CARGO_INCREMENTAL=0 for every Rust step. Incremental compilation is pure waste
# here: Woodpecker gives each workflow a FRESH 10Gi workspace PVC, so nothing is
# ever reused across pipelines, and the artifacts are enormous. Measured locally,
# `target/debug/incremental` was 11G of a 27G target tree — 41%.
#
# ── Why the release gate is no longer on the push path (2026-08-31) ────────────
# `mp_rolling_upgrade_no_loss_no_stall` gated the image build from m11p8 until
# today. It is MARGINAL on this hardware and has now been measured as such:
# pipelines #5 and #6 passed, #9 and #10 failed, all four on the same 3 CPU / 6Gi
# step and all four failing identically at
#
#   cluster_lifecycle.rs:362  timed out: WAL relay alone must reconverge all
#                             three nodes to 1e-6 after the rolling upgrade
#
# The same test on the same commit passes locally in 19.61s. It spawns three real
# tidal-server processes, each with its own WAL, HNSW index, gRPC transport and
# tokio runtime, and asks them to reconverge to 1e-6 inside 180s — on a node with
# ~1700m of free CPU shared with the production tidalDB cluster. Two passes and
# two failures is a coin flip, and a coin flip that blocks image builds is worse
# than no gate: it teaches everyone to re-run until it goes green, which is how a
# gate stops being one.
#
# Raising the budget again would be loosening a measured threshold to hide the
# hardware, so it was not done. This is the escalation the roadmap's own task 01
# prescribed: a tier-3 three-process test does not belong on a 4-CPU shared node,
# so it becomes a pre-release step run where it demonstrably passes
# (docs/runbooks/deploy-verification.md), and it still runs nightly inside
# `cluster_lifecycle` with the same budgets, where a flake costs a re-read of the
# morning report instead of a blocked release.
#
# What gates the image now is `fast-suites`: 51 tests across nine deterministic
# in-process suites, no spawned processes, no timing budget to starve. It catches
# the class of regression that actually reached main today — `cluster_routes`
# asserting a wire fabrication that had been deleted hours earlier.

steps:
  # ── Push gate: deterministic in-process suites ──────────────────────────────
  # These nine suites hold the guards that matter for a release and none of them
  # spawn processes or depend on a convergence budget, so their result means the
  # same thing on a loaded shared node as on a workstation. Measured 872s in CI
  # (mostly cold-cache rustc) and 71s locally.
  #
  # Fourteen of the 23 integration suites were run by NO pipeline before today.
  # That is how `cluster_routes` kept asserting `applied_events == 0` with a lag
  # derived from it — a fabrication deleted earlier the same day — and how the
  # dense-rank (`cluster_sharding`) and vector distance-contract (`vector_search`)
  # guards came to sit unexecuted. A failure here BLOCKS the image build below.
