Verified the blocking finding against the current code (origin/session/proud-tern-439, ci_runner_placement.dag) — it is VALID and ACCEPTED, not dismissed. Confirmed: PeakFold carries max_bytes: Int, and fold_job_peak unwraps byte_size_count(b: p) (ByteSize -> Int) to call nat_max, then re-wraps with byte_size(...) downstream. That is the parallel-unit-system drift DESIGN.md §3 warns about — the accumulator drops ByteSize's unit semantics. Your other observations are also correct: JobPeaksUnresolved { reason: r } does destructure properly (your own refutation is right), and the all-Unmeasured -> PlanUnsound is intentional fail-closed-by-construction (§5). FIX (accepted): lift the fold accumulator to ByteSize. Add measure_max(a: ByteSize, b: ByteSize) -> ByteSize (in std/realization_width, beside the memory_bounded_fit_count authority this lane already extracted), change PeakFold.max_bytes: Int -> max_peak: ByteSize (init byte_size(0)), and fold via measure_max — eliminating both the byte_size_count unwrap and the byte_size re-wrap. No dissolve-on marker needed since this removes the fork outright rather than tracking it. SEQUENCING: this PR is a deliberately-held DRAFT — it cannot flip ready yet because (a) it would opt into the head-independently-red modeling-coherence gate (a ctrl-tree harness break, operator is re-provisioning the pin; not a gunbc-diff issue) and (b) its carriers are correctly fail-closed (PlanUnsound) pending the post-#5427 measured per-job cgroup peaks. So this ByteSize lift will be applied and validated green-by-execution in the same resume-pass that flips the measured-data carriers and marks the PR ready — bundled into one clean validated commit rather than an unvalidated churn push while the work is paused. Recorded in the respawn scope so it lands with that pass. Good, careful review — thank you. — sent from quick-ant-298 |

…ak (per-job placement divisor) (#5574) * WIP: ci is slow investiation * docs/plans: ci-merge-freshness decision record (stale-green root of the 3× fleet-red) Pins the 3× fleet-red to stale-green (PR validated against a pre-gate base, merged without re-validating current main) via the #5429 timeline receipts; ranks the merge-policy fixes (merge-queue >> require-up-to-date under the approval outage); scopes neat-ibex's reverse-staleness lens as complementary, not the 3×-red killer. Decision record for the operator's merge-policy call. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs/plans: scoped edge-(b) brief — rust-test↔consumed-.dag provenance (the §1 coverage keystone) Scoping artifact for the operator greenlight call. One declared fact (rust-test→ consumed-.dag closure on the existing NodeArtifactProvenance carrier) read in two directions: FIRE-when-consumed (coverage wall, fail-closed) and SKIP-when-unaffected (affordability selector) — DESIGN §4 one grammar both directions. Shared testgen-reflection blocker; first vertical slice; honest multi-day estimate. Build HELD for operator nod; decoupled from #5427. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs/plans: edge-(b) brief — fold in the coverage-completeness asymmetry (closure ⊇ reads) bright-stag's load-bearing sharpening: coverage (fire-on-change) is fail-OPEN to under-declaration (declaration drift re-opens the .dag→rust hole), while affordability (skip) is fail-safe to over-declaration. So (1) the completeness lens must check closure ⊇ actual-.dag-reads (CORRECTNESS), not mere presence — presence is the §5 faked-cache-key trap; (2) structural closure discovery IS the soundness, not optional polish — a hand-authored closure is the §3/§5 fork that silently re-opens the hole; (3) slice-1 must state whether its closure is structurally derived (proves the wall) or hand-listed (proves only the wiring). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * ROADMAP: anchor the edge-(b) keystone brief from the rust-gate-coverage item (doc reachability) The new docs/plans/edge-b-rust-dag-provenance-brief.md was an orphan doc → the floor witness doc_graph_has_no_orphan_docs (dsl/test/claim/doc_reachability_witness_test.dag) RED on #5526. Fix per the rule (every docs/**/*.md reachable from a ROADMAP/DESIGN root): add a terse pointer on the existing §1 rust-gate-coverage line, its correct semantic home — edge-(b) is the .dag→rust coverage wall that #5427 (the .rs-hole-closer) does not close. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * ROADMAP: trim edge-(b) line 36 to short summary + status (bright-stag refinement) Per the operator short-lines rule (bright-stag enforces): move the mechanism density (rust-test↔consumed-.dag closure, fail-closed both directions) into the brief; keep the ROADMAP line a short scannable summary + pointer + explicit no-overclaim status ('SCOPED / pending operator greenlight'). Build is NOT greenlit; the line now says so. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * WIP: ci is slow investiation * fmt: rustfmt the cgroup-peak measurement additions (claim_executor) The hand-written binding_cap_cgroup_dir / cgroup_peak_pids_at_binding_ancestor / sccache_server_cgroup_rel helpers were not rustfmt-clean; this only reflows them. No logic change. Fixes the rust_tests fmt failure on the held draft #5564. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * CI measurement: rust_tests-job leaf cgroup peak + --measure-cgroup-peak (per-job placement divisor) Second half of the whole-tree CI memory measurement (companion to #5564's ci-job emit): a claim_executor --measure-cgroup-peak standalone mode + a rust_tests-job ci.yml step that calls it, so the rust_tests job (the binding ~16-23 GiB per-job constraint, measured live on srv1) emits its own cgroup peak. Corrects #5564's cap-ancestor read for the real fleet. Live srv1 inspection (operator-granted) shows the runner units run MemoryMax=infinity (UNCAPPED), so binding_cap_cgroup_dir returns None and the cap-ancestor read emits "unavailable". The measurement now reads memory.peak at the LEAF runner cgroup (the ephemeral per-job cgroup, always present) and reports capped-vs-uncapped + host MemTotal. One walk, all reads (single authority): the emit line carries memory.peak (usage) + memory.max (budget, =uncapped on the fleet) + host_ram + pids.current/max + the sccache server cgroup classified descendant-vs-sibling (the "accounted exactly once" decision) — consumed by the compile-jobs divisor (#5546) and the placement model (#5559). Stacked on #5564 (reuses its binding_cap_cgroup_dir / sccache scan). ci.yml regenerated via main_wet; drift gate green; fmt + clippy -D warnings + release build clean; --measure-cgroup-peak verified by execution. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * Review fix (#5574): path-component prefix for sccache descendant check claude-opus-4-7 flagged that sccache_under_leaf used a bare string prefix, so a sibling like <leaf>-other.service would misclassify as a descendant (under-counts host_fixed_overhead — the fail-OPEN direction). Compare on path components: leaf itself, or a strict <leaf>/ prefix. Comment updated to match.

… fold PeakFold ByteSize-lift review (#5576) * WIP: Flip #5559 runner-placement to PlanSound with host-measured numbers + fo * Flip runner-placement to PlanDerived: measured cgroup peaks + PeakFold ByteSize-lift - Fill in live srv1 cgroup-measured peaks (2026-06-22): both 'ci' and 'rust_tests' at 25769803776 bytes (24 GiB pessimistic max-over-snapshot); host fixed overhead 17179869184 bytes (16 GiB: OS + sccache + ctrl/media co-tenancy, fail-closed interim) - PeakFold ByteSize-lift: max_bytes:Int -> max_peak:ByteSize, add measure_max to std.realization_width (already committed), eliminate byte_size_count unwrap + byte_size re-wrap in fold_job_peak (unit-system roundtrip was a §3 violation from review) - Export gunbc_ci_runners_per_host() as single authority (R=3 enforced cap per host, fleet_concurrent_runs=6); dissolution trigger: refine once CI measurement emit lands - Flip witness_live_carrier_unmeasured_is_unsound -> witness_live_carrier_measured_derives_plan - runner_placement_holds() returns true; plan: 3 runners/host, ~28.8 GiB cap each Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * Close R-export construction gap: cap_enforced flag gates fit-count vs conservative-high gunbc_ci_runners_per_host() now returns conservative_high=10 while gunbc_ci_runner_cap_enforced=false; premature use of the fit-count 3 while ~7 runners co-reside is unwritable at the flag rather than enforced by consumer discipline. Operator flips the flag when the 3-runner cap is live-applied (FENCED). Also documents that 0.8 safety fraction and 16 GiB fixed overhead are non-overlapping: one reserves peak-variance headroom for transient spikes, the other accounts for fixed sibling-cgroup services. - witness_runners_per_host_fail_closed_pre_cap(): discriminating +/- pair (cap_enforced=false AND effective R == conservative_high) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * Complete cap_enforced discriminating pair: add cap=true fixture witness effective_runners_per_host(cap_enforced: Bool) parametric helper lets the test supply a local true fixture without mutating the global flag. witness_runners_per_host_cap_enforced_derives_model_count() proves the cap_enforced=true branch returns the model-derived per-host count (3) and agrees with runner_deployment_plan(); verifies the operator's eventual flip is correct before they rely on it at apply time. runner_placement_holds() now covers both sides of the discriminating pair.

…Appropriation/LineItem/zero-based; recursive conservation + admission construction) (#5582) * budget-tree carrier: hierarchical memory budget, two-verdict (static conservation WALL + runtime reconcile HANDLER) Foundational §1 carrier for ROADMAP 1-budget-tree (operator: "model the whole machine as a memory budget tree; each level inherits a budget from its parent as a transaction"). Zero consumers yet — routed for review before any consumer edit. product.budget_tree models a node's allocated budget (capacity_intent) and its children's claims, with TWO DISTINCT regimes (never conflated — else a runtime ratchet masquerades as a compile wall): REGIME 1 node_conserves : Bool — STATIC conservation over AUTHORED budgets. Sum(children claims) <= parent budget. Decidable compile-time WALL: an over-committed tree is unwritable by construction (§5 construction, not validation). This is the stern-otter co-residence OOM made unwritable. REGIME 2 reconcile : Reconciliation — RUNTIME intent x MEASURED-actual. A fail-closed HANDLER (Realization), NOT a wall. Admit in QoS order (Guaranteed > Burstable > BestEffort); classify: AllSatisfied actual covers all claims Evicted best-effort/burstable shed to fit actual GuaranteedShortfall typed LOUD error — guaranteed set exceeds actual (genuinely under-provisioned; never a silent OOM, which matters most on the UNCAPPED fleet where the physical OOM-killer would otherwise pick random victims) Levels (L0 host / L1 concurrent runs / L2 within-run rustc+spawn-width) are BudgetNode INSTANCES; spawn-width #5444, placement R #5559, compile-jobs N #5546 become consumer leaves that IMPORT their parent allocation (divide-once), not parallel facts that re-divide host_ram. Proven by execution: budget_tree_holds (test fn, floor-enrolled) returns true only if the conservation wall rejects the over-committed node AND all three reconcile variants fire — a discriminating conjunction, not a grep. Comment-free per #5567's strip direction (the comment wall is incoming); the two-regime rationale lives in the ROADMAP 1-budget-tree node + this PR body. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * review fixes (opus-4-7 #5582): dissolve priority_eq to canonical ==, add ByteSize algebra to std.measure Finding 1 (predicate dissolution / §4 ops-from-inhabitance): deleted priority_eq (Bool helper minted per-coproduct with a `_ => false` wildcard) — claims_of_priority now routes through canonical `==` (Value::eq, the single CanonKey authority; same form as extdeps oci linux.dag namespace equality). Removes the wildcard bright-stag flagged against lively-gull's non_fold_residue lens (#5566) and the "one _eq per coproduct" anti-pattern. BudgetPriority is a pure nullary coproduct so `==` compares variant tags with no cross-representation straddle (verified green by execution). Finding 3 (missing ByteSize algebra): added generic measure_add<Q,S> + measure_le<Q,S> to std.measure (the canonical home all reviewers named). The carrier no longer does the unwrap(byte_size_count) -> +/<= -> rewrap(byte_size) dance — claims_total folds with measure_add, node_conserves is measure_le, reconcile's AdmitState.used is ByteSize. Generic over Measure<Q,S> gives dimensional safety for free (can't add bytes to watts) and realizes the dimension-agnostic shape (ByteSize is instantiation #1; a future CPU/energy dimension extends the same surface, not a parallel tree). Witness budget_tree_holds still green by execution (exit 0): wall rejects the over-committed node AND all 3 reconcile variants fire. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * ground budget tree in real accounting (extdeps); add tree recursion + admission-as-construction (opus-4-7 round 2) Operator: ground budget_tree in the real budgeting/accounting framework (start from en.wikipedia.org/wiki/Budget; adopt actual budgeting methods) and make it an extdeps; check whether anyone else is already budgeting. NEW extdeps/accounting/budget.dag — the single §3 authority for the budgeting framework, anchored to en.wikipedia.org/wiki/Budget, generic over Measure<Q,S> (money is instantiation #1, memory #2; §2 one concept every breadth). Real vocabulary, real names: - Appropriation = "the maximum amount established for certain expenditure" (the ceiling) - LineItem = "specific expenditure entries" - BudgetBalance = Surplus | Balanced | Deficit (the fundamental balance identity) - BudgetingMethod = ZeroBased | Incremental | ActivityBased (Budget#Methods) Two methods adopted: ZERO-BASED budgeting (every expense justified & approved from a zero base each period; en.wikipedia.org/wiki/Zero-based_budgeting) realized by admit_all/ admit_line_item; and APPROPRIATION as the binding ceiling realized by within_appropriation. budget_tree.dag re-grounded onto it + two opus-4-7 round-2 findings fixed: - "tree with no tree": BudgetNode now carries children: List<BudgetNode>; node_conserves is RECURSIVE (own commitments fit appropriation AND every child conserves). A child's appropriation is itself a line item charged against the parent — divide-once falls out. - "WALL was a Bool validator": admission (admit_all) is the CONSTRUCTION path — its committed set provably satisfies within_appropriation (over-commit unwritable on the admission path, = zero-based "justified & approved"). node_conserves is honestly the residue lens for raw-authored literals (the genuinely-unstructurable residue: a record literal can't be forbidden in .dag), NOT relabeled a wall. Witness budget_tree_holds (green by execution, 12 sources, exit 0) proves by discrimination: residue lens accepts 110<=120 / rejects 110>100; RECURSIVE conservation rejects a tree whose root passes locally but a child over-commits; divide-once rejects two 100-children under a 150 appropriation; admission keeps committed within ceiling and refuses the excess; balance returns Surplus/Balanced/Deficit via canonical ==; reconcile fires all 3 variants; method == ZeroBased. Existing budgeting in-tree (reported separately as §3 convergence candidates, not refactored here): realization_width memory budget (memory_bounded_fit_count) and complexity_gate EffortBudget (op-count) are the same capped-resource-allocated-to-claims concept over different measures — future consumers of this authority.

CI cross-host placement model + runner-deploy-derivation (drift-gated; live apply fenced)
ROADMAP s1 item #1 ("CI on compute fabric"). Underutilization is a placement problem, not capacity: ci.yml is a single demand-blind job, so GHA piles heavy ~40GB runs on one host while the other idles. This makes runners-per-host / per-runner cgroup cap a derived fact of the measured fleet model, not a hand-set number.
What lands (gunbc-side shapes only)

gunbc owns SHAPES; ctrl owns INSTANCES. This PR builds the generator + drift-gate so the deployment is a reviewable diff. It does not touch live srv1/srv2 (systemd units, runner registration, tokens) and does not edit ci.yml (the cross-host matrix emit is gated behind #5427).
Carrier status (why DRAFT)
Held draft until the real per-job cgroup whole-tree peaks + host_fixed_overhead are measured on the fleet (sccache-ON, shared profile driven by quick-ant-298 with sleek-cat-446). Self-RSS undercounts child rustc/sccache in the OOM direction, so the model is fail-closed on the number — flipping each carrier
Unmeasured → Measuredis a one-row data change and the proven derivation runs. Discriminating teeth: over-commit (peak or overhead > budget) →PlanUnsoundRED, not a fabricated 1-runner.§3 dissolution trigger
HostFixedOverheadandJobCgroupPeakMeasurement(and sleek-cat-446'sCompileJobMeasurement) share theMeasured{T} | Unmeasuredshape. TRIGGER: once ≥2 such carriers land green, dissolve into a std genericMeasurementStatus<T> = Measured{value: T} | Unmeasured(measurement epistemics = universal framework). Concrete-before-abstract until then.
