… fabric" Centralize all srv1/srv2 management/modeling under the fabric: one host ResourceEnvelope authority, every resource/parallelism knob derived from it and generated (gunbc owns unit shapes, ctrl owns instances). Enumerate the dimensions now (pids cap/TasksMax, jobserver tokens, spawn_width, build fan-out, MemoryMax, watchdog, runner topology) so they aren't forgotten — the EAGAIN clone-reject flake, spawn_width OOM, and MemoryMax drift are all one un-modeled-envelope root. Names the parallelization-by-realization arm as the single carrier with §2 caching. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

main's compact bullet (#5459) said 'spawn_width (memory- & pids-aware)' — the same conflation quick-ant corrected in compute-envelope-model.md. spawn_width is RUN-phase (cores∧mem, prebuilt binary, pids-light); pids binds the BUILD phase (fan-out × concurrent-builds). Keeps ROADMAP consistent with the doc in one PR. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

…r one authority) (#5462) * docs/plans: compute-envelope-model — one authority for the CI fleet's resource dimensions Plan doc resolving the §1 ROADMAP "CI on compute fabric" pointer. Models the bimodal crash-or-idle pathology as one root (N hand-tuned resource dimensions, no single ResourceEnvelope authority) and the §3 fix: derive every knob — spawn_width, fan-out, TasksMax, jobserver, MemoryMax — from one measured envelope, with the public(shape)/ctrl(realization) split. Co-owned warm-lark-306 + quick-ant-298 (§1 lead); CC bright-stag-194 (ROADMAP + test profile). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * compute-envelope-model: correct current width = pinned 4 (quick-ant verified) Memory-aware width model was removed as unwired (#5419); current floor width is a pinned constant 4 (ci_floor_plan.dag:292), ~3% of 128c. #5444 re-adds the memory term (not yet on main). The lever lifts both the pin and the shard_count cap from the envelope. Fresh spawn-width slice to be reopen-scoped by quick-ant. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * ROADMAP §1: point the CI-on-fabric chore-line at the compute-envelope plan doc Makes #5462 self-contained (doc + its own pointer, atomic, no orphan window). Different line from the §1 nightly-reframe edits — no collision. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * compute-envelope-model: split RUN-phase width from BUILD-phase pids (quick-ant) The §3 invariant conflated two phases. spawn_width is the discovery-corpus RUN-phase shard width (witnesses against the prebuilt binary — cores∧mem-bound, pids-light), so it does NOT multiply per_build_pids; width-up is pids-safe on its own. The pids crash is the BUILD phase: concurrent_builds × per_build_pids ≤ pids_cap, coupling host-packing × fan-out, not spawn_width. Two invariants, not one product. Also: #5375 memory-aware was superseded by #5419's pin (#5444 re-adds the term). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * ROADMAP §1: fix chore-line spawn_width conflation (RUN/BUILD split) main's compact bullet (#5459) said 'spawn_width (memory- & pids-aware)' — the same conflation quick-ant corrected in compute-envelope-model.md. spawn_width is RUN-phase (cores∧mem, prebuilt binary, pids-light); pids binds the BUILD phase (fan-out × concurrent-builds). Keeps ROADMAP consistent with the doc in one PR. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * ROADMAP §1: adopt quick-ant's precise spawn_width de-conflation wording Explicit RUN/BUILD phase labels — spawn_width = cores∧mem (RUN, prebuilt binary, pids-light); pids burst belongs on per-build fan-out (BUILD, concurrent_builds × per-build-pids ≤ TasksMax). No "pids" on the spawn_width bullet at all (the conflation's verification check). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * ROADMAP §1: shorten CI-on-fabric chore-line to a summary + doc pointer Per operator: ROADMAP lines stay scannable progress summaries; density goes in plan docs (its own stated rule — no restating detail). The 1175-char inline chore-list/diagnosis/formulas now live in compute-envelope-model.md; the line is a one-sentence summary + pointer. Density preserved in the doc, not lost.
