Test dispatch outcome per Director #issuecomment-4381542467 + Mgr dispatch on inbox #1752.

Primary Evaluator brief: docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md.

Manager note: branch currently also includes ROADMAP.md and docs/r2-closure-ledger.md changes from stale Release/R2 work. Those are not part of the R3 Evaluator E5 STOP packet and must be removed or explicitly rerouted before this PR is eligible for disposition. Opening as draft to preserve the pushed worker artifact and unblock review visibility.

Manager feedback for sharp-ibex-91:

Manual PR-open workaround succeeded for your pushed branch. The expected Evaluator artifact is present: docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md.

However, the branch also includes ROADMAP.md and docs/r2-closure-ledger.md changes from stale Release/R2 authority. Those files are outside the R3 Evaluator E5 LoopBound::Descent STOP-packet scope. Please clean the branch so the PR contains only the E5 STOP packet unless Director/operator explicitly reroutes those stale Release/R2 edits. Keep this PR draft until that cleanup is complete.

APPROVE — docs-only STOP packet adding a single brief under docs/briefs/. No code, substrate, or test changes. The document is internally consistent, correctly describes the existing fail-closed LoopBoundDescentResidual behavior, and explicitly disclaims widening LoopBound, evaluator-local proof inference, or substrate edits. Nothing in the diff touches INVARIANTS/MODELING/CODING/TESTING surfaces.

  • Thinking: 68s wall

Verdict: APPROVE — The diff adds an E5 coordination brief that matches fail-closed / single-authority framing for LoopBound::Descent, and swaps the T-Demo fixture helper to cached_compile_to_dag, which matches the documented amortization pattern in TESTING.md and preserves the clean-compile contract (still panics with diagnostics on semantic failure). No invariant or modeling-discipline breach visible in these edits.

Exploratory (optional): In docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md, the opening “docs-only audit packet” wording can read as if the whole PR is documentation-only, while integration.rs also changes; a short clarifier (e.g. that the packet is the doc deliverable, with an optional test harness tweak) would avoid that ambiguity. The git-metadata-unavailable status stub is a bit opaque for readers outside the R3 workflow.

Non-blocking — Strengths

  • docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md Mixed PR, primarily design/docs; the STOP packet preserves the fail-closed LoopBound::Descent boundary and names the missing proof authority without widening substrate or adding evaluator-local inference.
  • src/v3/compiler/tests/integration.rs The Rust change is implementation-local test caching; cached_compile_to_dag preserves the clean-vs-semantic outcome authority and does not alter compiler substrate behavior.

✅ No blocking concerns.

  • Thinking: 21s wall

Findings: None. The diff adds an E5 STOP brief (documentation only), bumps the slow-test exemption ratchet with a matching entry that names paydown ownership (scripts/slow-test-exemptions.txt / scripts/check-test-timeout.sh), and switches T-Demo fixture compilation to cached_compile_to_dag (src/v3/compiler/tests/integration.rs), which still enforces a clean compile via CachedCompileOutcome::Clean and panics on semantic-error outcomes (cached_compile.rs behavior — aligned with TESTING.md on amortization without changing logical test contracts). Nothing here touches substrate modeling, duplicate authorities, or fail-closed compiler/runtime paths in executable code.

Verdict: APPROVE — Narrowly scoped docs plus CI/test-harness tuning; no concrete violations of INVARIANTS.md, docs/modeling-discipline.md, CODING.md, or TESTING.md observed in this diff.

APPROVE — docs-and-CI-only diff. The PR adds an E5 STOP packet that explicitly defers descent execution, widens the Stage 2d CI wall budget (300→360s), bumps the slow-test exemption ratchet (39→41) with two new entries that include named paydown triggers, and swaps the T-Demo fixture compile to the shared cache helper. No substrate, evaluator, parser, lowerer, or runtime changes — and the packet itself reinforces fail-closed handling of LoopBound::Descent rather than weakening it. Exemptions cite PR # and ms measurements and name dissolution triggers, so they qualify as tracked debt. Nothing in the diff conflicts with INVARIANTS, modeling-discipline, CODING, or TESTING.

1. Story of the diff

This PR does not implement LoopBound::Descent; it writes down the opposite contract: E5 remains stopped until a termination-proof authority exists. The new STOP packet narrows the live surface to LoopBound::Descent { cluster, measure }, rejects evaluator-local inference/defaulting, and sketches the future proof-query shape that would let the evaluator consume certified descent execution directly (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:22-25, :117-143). Around that documentation change, the PR keeps CI/test performance pressure explicit: Stage 2d’s cold-compile budget is widened from 300s to 360s, the slow-test exemption cap is raised from 39 to 41, two named exemptions are added with measured overages and paydown owners, and T-Demo fixture compilation switches to the shared cached_compile_to_dag path (.github/workflows/ci.yml:195-202, scripts/check-test-timeout.sh:49,58, scripts/slow-test-exemptions.txt:70-71, src/v3/compiler/tests/integration.rs:209,228). I applied the supplied invariant/testing rubrics as the review frame. chatgpt-review-a2f0ea08-b7e2-43…

chatgpt-review-a2a1c9bd-77f9-40…

2. Invariant categories

  1. LAYER MODEL (substrate vs implementation).

Compliant — the PR explicitly avoids substrate/runtime mutation: the STOP packet says it “does not implement descent execution, change parser/lowerer/runtime code, widen substrate carriers, add runner behavior, or alter evaluator strategy” (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:5-8), and later repeats “do not … edit parser, lowerer, runtime, or substrate carriers” (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:104-113). This is implementation/docs/CI-only, not a new Dag/substrate shape.

  1. INVARIANTS.md + modeling-discipline.md.

Compliant — fail-closed and single-authority discipline are the main point of the packet: LoopBound::Descent “must not be reinterpreted as a cardinality loop, defaulted to zero, widened with new evaluator-local fields, or executed by locally inferring proof facts” (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:22-25). The future route is also single-authority rather than heuristic: the packet requires an evaluator-consumable contract keyed by (Dag, ClusterId, measure: PortId) (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:76-82) and says missing/unknown/incomplete evidence returns a typed residual/diagnostic without executing (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:138-143).

  1. CODING.md.

Compliant — the only Rust test change moves fixture compilation to an existing free-function cache, cached_compile_to_dag(source, FIXTURE), rather than adding new object state, a method surface, or hidden production dependency (src/v3/compiler/tests/integration.rs:209,228). The shell ratchet also keeps dependencies explicit through TEST_TIMEOUT_MAX_EXEMPTIONS and a literal default (scripts/check-test-timeout.sh:58).

  1. TESTING.md.

Compliant — no new behavioral test is required because the PR intentionally adds no descent behavior; the packet is a STOP/audit deliverable (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:3,102). The test-infra changes are bounded and documented: the exemption ratchet is raised to 41 (scripts/check-test-timeout.sh:49,58), and the two new exemptions each name the slow fixture, measured CI edge, and paydown owner/trigger (scripts/slow-test-exemptions.txt:70-71). The T-Demo compile change uses shared cached compilation for a full fixture, which is consistent with amortizing identical integration-test inputs (src/v3/compiler/tests/integration.rs:228).

  1. LOCKED DESIGN DECISIONS.

N/A — the diff does not edit a locked thesis/design decision file. It does reference E5 policy, but in a constraining direction: “STOP implementation until termination-evidence authority is assigned” and no widening/runner/evaluator strategy changes (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:100-113).

  1. TRACKED vs UNTRACKED DEBT.

Compliant — the new temporary performance exceptions are tracked bridges, not silent drift: the cap is updated to the exact new floor of 41 (scripts/check-test-timeout.sh:58), and each added exemption carries documentation, a bound/measurement, and a named paydown owner (scripts/slow-test-exemptions.txt:70-71). The E5 STOP itself also has a dissolution trigger: resume only once a proof authority exists, with a suggested descent_execution_proof(...) -> Result<DescentExecutionProof, DescentResidual> contract (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:117-148).

3. Verdict

APPROVE. The diff keeps LoopBound::Descent fail-closed, avoids substrate/runtime changes, and tracks the added CI/test debt with explicit caps and paydown triggers. I did not find a changed line that warrants a blocking or non-blocking finding.

  • Thinking: 28s wall

Verdict: APPROVE — The diff is almost entirely an E5 audit STOP brief, CI/test-timeout housekeeping, and a one-line import cleanup in integration.rs. Nothing here weakens substrate modeling, introduces parallel authority, or relaxes fail-closed execution semantics; the new brief explicitly forbids widening LoopBound, evaluator-local proof inference, and executing LoopBound::Descent without a termination-evidence authority, which matches P3 Fail-Closed and P4 framing in INVARIANTS.md. The slow-test exemption line documents paydown ownership and points at a spec doc, satisfying the usual tracked debt pattern described around scaffolds/exemptions in TESTING.md. No findings requiring changes surfaced from diff-grounded review against those rubrics.

1. Story of the diff

This PR deliberately stops short of implementing LoopBound::Descent. The new packet documents that cardinality loops are already executable, but descent loops remain a residual until a real termination-evidence authority exists; the packet names the missing contract, forbids evaluator-local inference or reinterpretation, and sketches the future proof-query shape as a consumer of existing cluster/descent facts (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:22-25, :95-98, :117-143). Around that documentation change, the PR makes CI/test-budget maintenance changes: Stage 2d’s cold-compile wall budget is widened from 300s to 360s, the slow-test exemption ratchet is raised from 40 to 41, and the new R3-V fixture exemption records a concrete observed runtime plus a paydown owner/trigger (.github/workflows/ci.yml:195-202, scripts/check-test-timeout.sh:49-58, scripts/slow-test-exemptions.txt:70). The integration test edit is only a local import cleanup for cached_compile_to_dag, not a behavior change (src/v3/compiler/tests/integration.rs:209, :228).

2. Invariant categories

  1. LAYER MODEL (substrate vs implementation). Compliant — the packet explicitly says it does not “change parser/lowerer/runtime code” or “widen substrate carriers,” and later repeats “Do not … edit parser, lowerer, runtime, or substrate carriers as part of this audit” (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:7-8, :106-113). No substrate type, Dag carrier, or new variant is introduced in the diff.
  2. INVARIANTS.md + modeling-discipline.md. Compliant — fail-closed and single-authority discipline are the center of the packet: LoopBound::Descent must not be defaulted, widened locally, reinterpreted as cardinality, or executed by local proof inference (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:22-25). The proposed resume shape also preserves facts-flow-forward by making eval_loop a narrow consumer of a proof query over existing Dag.clusters, IntraClusterCall.transform, MemberDescent.param, and termination evidence facts, with unknown/incomplete evidence returning a typed residual instead of executing (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:130-143).
  3. CODING.md. Compliant — the only Rust-facing change is an import/local-call cleanup: the module imports cached_compile_to_dag once and then calls the function directly, instead of qualifying through crate::common at the call site (src/v3/compiler/tests/integration.rs:209, :228). No new method-heavy API, hidden mutable state, panic surface, or unstructured error carrier is added.
  4. TESTING.md. Compliant — no new behavior implementation is added, so no new evaluator regression test is required in this PR. The test-suite maintenance is explicit: the new slow-test exemption names the exact fixture, explains why it can exceed the 2s edge, records the observed 2072ms PR measurement, and names the paydown lane/trigger (scripts/slow-test-exemptions.txt:70). The exemption ratchet is raised in lockstep from 40 to 41, preserving the bounded-exemption check rather than silently allowing unbounded growth (scripts/check-test-timeout.sh:49, :58).
  5. LOCKED DESIGN DECISIONS. N/A — the diff does not alter a locked design surface. It references existing design/source facts and explicitly stops implementation until the missing termination-evidence authority is assigned (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:95-102).
  6. TRACKED vs UNTRACKED DEBT. Compliant — the new slow-test scaffold is tracked: documentation is present in the exemption comment, the bound is the 2s timeout/2072ms observed edge plus the global exemption cap of 41, and the dissolution trigger is the R3-V L4/L7 direct harness shared-runner setup named in the same line (scripts/slow-test-exemptions.txt:70, scripts/check-test-timeout.sh:49-58). The STOP packet is also bounded debt rather than open-ended drift: it names the missing executable contract and the condition for resuming E5 implementation, namely a termination proof query that fail-closes on missing/unknown/incomplete evidence (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:74-98, :117-148).

3. Verdict

APPROVE

This PR keeps LoopBound::Descent fail-closed, avoids substrate/evaluator mutation, and documents the missing authority instead of smuggling in a local execution rule. The CI/test-budget changes are bounded and tracked, with the new exemption carrying enough context and a named paydown path.

  • Thinking: null

APPROVE — Diff is documentation (E5 STOP packet brief) plus CI/timeout tuning, one slow-test exemption with a paydown-tracked rationale, and a trivial use-statement hoist in integration.rs. No substrate carriers, evaluator code, or invariant surfaces are touched. The STOP packet itself is consistent with fail-closed discipline (explicitly forbids widening LoopBound, evaluator-local proof inference, or reinterpreting Descent as cardinality) and proposes a single Substrate-owned descent_execution_proof authority — aligned with single-authority/facts-flow-forward.

Minor non-blocking observations:

  • The new exemption at scripts/slow-test-exemptions.txt:70 and ratchet bump 40 → 41 in scripts/check-test-timeout.sh:49,58 are properly paired and reference a paydown brief — tracked debt, fine.
  • The CI budget bumps (ci.yml:195,200,323) are unbacked by data in the diff itself beyond the commit messages; acceptable for an infra knob, but worth confirming the 360s/60-min ceilings aren't hiding a real regression rather than cold-cache variance.

Confirmed the CI budget side: the 60-minute self_host_ratchet bump is not speculative. Run 25405822513 on head 9fb3f6b cancelled exactly at the prior 30-minute job timeout while DB-8 self_host_fixed_point (staged) was still running; the preceding DB-8 determinism_test step had passed. The job is already continue-on-error, but a timeout still reports the check as cancelled/unstable, so the ceiling needs to exceed the staged release-build runtime. The 360s Stage 2d budget is likewise scoped to the cold-compile-safe integration module lane, with the per-test ratchet still enforcing the 2s test-level bound plus the tracked exemption count.

  • Thinking: 64s wall

Findings: None. The diff only adds the E5 STOP brief, CI wall budgets, one slow-test exemption with an explicit paydown owner and doc pointer, bumps the exemption ratchet floor to match, and a trivial cached_compile_to_dag import in integration.rs. Nothing here weakens fail-closed execution of LoopBound::Descent (no evaluator/substrate changes), and the brief’s STOP plus “resume via a proof query” framing matches P3 (fail-closed) and P5 (named dissolution / no silent bridge) rather than contradicting them. The new exemption line matches TESTING.md’s pattern (named paydown, not bare silence). docs/modeling-discipline.md items (new enum classification, illegal states, etc.) do not apply—no new substrate types or multi-variant Rust enums in this diff.

Verdict: APPROVE — Narrowly scoped audit packet and CI/test harness housekeeping; no rubric violations tied to specific diff lines.

Exploratory (optional): In docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md, the status line embedding `git-metadata-unavailable` reads like automation residue; consider a one-line human gloss for non-tool readers (purely editorial, not blocking).

1. Story of the diff

This PR is primarily a STOP packet for E5 LoopBound::Descent, not an implementation of descent execution. The new brief draws a hard boundary around the already-live cardinality loop path, then preserves LoopBound::Descent { cluster, measure } as a fail-closed residual until a real termination-evidence authority exists. The load-bearing mechanism is documentary but precise: it names the missing evaluator-consumable contract, forbids local evaluator inference/reinterpretation/widening, and sketches the future proof-query shape that would let eval_loop become a narrow consumer instead of an authority. Around that packet, the diff loosens several CI/test-budget ratchets: Stage 2d’s wall budget goes 300s→360s, the self-host ratchet timeout goes 30m→60m, and one slow-test exemption is added with the timeout script’s exemption ceiling raised from 40→41. The only Rust hunk is a small import cleanup in integration.rs, changing an existing crate::common::cached_compile_to_dag(...) call to a directly imported cached_compile_to_dag(...).

2. Invariant categories

  1. LAYER MODEL — Compliant. The diff does not mutate substrate carriers or Dag code; the packet explicitly says it “does not implement descent execution, change parser/lowerer/runtime code, widen substrate carriers, add runner behavior, or alter evaluator strategy” at docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:7-8, and later forbids widening LoopBound or editing parser/lowerer/runtime/substrate carriers in this audit at docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:106-113.
  2. INVARIANTS.md + modeling-discipline.md — Compliant. Fail-closed and single-authority discipline are the core of the packet: docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:22-25 says descent must remain fail-closed and must not be reinterpreted/defaulted/executed by local proof inference, while docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:117-127 requires a Substrate-owned or Director-assigned descent_execution_proof(...) -> Result<...> authority before resuming execution.
  3. CODING.md — Compliant. The only Rust change keeps the helper as a pure data-in/data-out wrapper and makes the dependency explicit with use crate::common::cached_compile_to_dag; at src/v3/compiler/tests/integration.rs:209, then calls that helper directly at src/v3/compiler/tests/integration.rs:228; no new method surface, hidden state, panic path, or object-style API is introduced.
  4. TESTING.md — Compliant. No executable semantics are added, so no new behavior test is required for the STOP packet itself. The slow-test budget change is still finite rather than disabled: Stage 2d now fails over 360s at .github/workflows/ci.yml:201-202, and the new exemption is a specific test row with reason, observed edge, and paydown owner/path at scripts/slow-test-exemptions.txt:70, bounded by the script ceiling at scripts/check-test-timeout.sh:58.
  5. LOCKED DESIGN DECISIONS — N/A. The diff does not alter a locked design decision or substrate design doc; it adds a coordination brief that explicitly preserves the current fail-closed residual shape and blocks implementation until the missing authority is assigned.
  6. TRACKED vs UNTRACKED DEBT — Finding, NON-BLOCKING. .github/workflows/ci.yml:323: timeout-minutes: 60 widens the self_host_ratchet timeout and supplies a bound, but the changed line is not paired with documentation or a named dissolution/ratchet-back trigger. That is different from the new slow-test exemption at scripts/slow-test-exemptions.txt:70, which names the slow fixture and paydown lane. This is not a substrate issue, but as P5 tracked-debt discipline, the timeout widen should carry an adjacent reason and a checkable trigger for reducing it again.

3. Verdict

APPROVE_WITH_COMMENTS

The E5 STOP packet is structurally aligned with fail-closed and single-authority discipline, and the diff does not introduce evaluator/substrate behavior. The only issue I see is non-blocking: the self-host timeout increase should be tracked with the same documentation-and-paydown standard used for the slow-test exemption.

  • Thinking: 23s wall

Findings: None. Nothing in this diff contradicts the cited rubric in a concrete way: substrate execution paths are unchanged; the E5 brief explicitly records STOP, fail-closed expectations, and a named resume shape (aligned with P3/P5 and modeling “tracked bridge” expectations). CI budget and slow-test exemption edits carry explicit paydown/ownership notes; the cached_compile_to_dag change in integration.rs is style-only and keeps the same hermetic test entry point described in TESTING.md (amortization cache, not cross-test shared logical state).

Verdict: APPROVE — Small, well-scoped mix of audit documentation, CI headroom, and a justified slow-test exemption; no invariant or modeling-discipline violations tied to these lines.

This PR is primarily an E5 STOP receipt: it records that LoopBound::Cardinality execution is already closed, while LoopBound::Descent { cluster, measure } must remain a fail-closed residual until a real termination-evidence authority exists (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:13-26). The packet deliberately avoids changing evaluator, lowerer, runtime, substrate carriers, or runner behavior (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:6-9), then names the missing executable contract and sketches the future proof-query shape the evaluator should consume (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:77-94, docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:118-144).

The rest of the diff is CI/test-ratchet maintenance: Stage 2d gets a temporary 360s wall budget with a ratchet note (.github/workflows/ci.yml:195-205), the self-host ratchet job timeout is widened to 60 minutes with a DB-8 paydown trigger (.github/workflows/ci.yml:326-329), one slow-test exemption is added with measurement and paydown ownership (scripts/slow-test-exemptions.txt:70), and a tiny test helper import removes a qualified path (src/v3/compiler/tests/integration.rs:209, src/v3/compiler/tests/integration.rs:228).

  1. LAYER MODEL — Compliant. The diff is substrate-adjacent documentation, not a substrate mutation: the STOP packet explicitly says it does not “widen substrate carriers” or alter evaluator strategy (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:6-9), and the do-not list forbids widening LoopBound, evaluator-local proof inference, parser/lowerer/runtime edits, or substrate-carrier edits in this audit (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:107-114).
  2. INVARIANTS.md + modeling-discipline.md — Compliant. Fail-closed and single-authority are handled directly: LoopBound::Descent must not be reinterpreted, defaulted, widened, or locally inferred in eval_loop (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:23-26), and the future execution path is constrained to a proof query whose missing/unknown/incomplete/non-strict evidence returns a typed residual or diagnostic without executing (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:139-144). Facts-flow-forward is also respected by naming the exact missing contract from (Dag, ClusterId, measure: PortId) to a validated proof (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:77-83) and listing the cluster, call, member-descent, measure, and scheduling facts that authority must answer (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:85-94).
  3. CODING.md — Compliant. The only Rust source change stays small and explicit: src/v3/compiler/tests/integration.rs:209 imports cached_compile_to_dag, and src/v3/compiler/tests/integration.rs:228 calls that helper directly from compile_fixture; this does not add methods, hidden state, panics, builders, or new result-shape ambiguity.
  4. TESTING.md — Compliant. No new evaluator behavior lands, so no new runtime regression test is required in this PR; the packet says it does not implement descent execution or alter runtime behavior (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:6-9). The future test obligation is named for the resume slice: focused tests should prove certified descent executes and uncertified descent remains fail-closed once the proof authority exists (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:146-149). The slow-test change is tracked rather than hidden: the added exemption includes the observed 2072ms measurement and the paydown owner/path (scripts/slow-test-exemptions.txt:70), while the exemption cap is raised coherently to 41 (scripts/check-test-timeout.sh:49, scripts/check-test-timeout.sh:58).
  5. LOCKED DESIGN DECISIONS — N/A. No locked thesis/design document is edited in the diff, and the new packet records a STOP boundary rather than a divergence; the relevant lines explicitly avoid substrate, evaluator-strategy, parser, lowerer, runtime, and runner changes (docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:6-9, docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md:107-114).
  6. TRACKED vs UNTRACKED DEBT — Compliant. The temporary CI headroom is documented, bounded, and given dissolution triggers: Stage 2d names the ratchet back toward 300s after cold lane2d runs stabilize and fixture compile amortization lands (.github/workflows/ci.yml:195-205), self-host names DB-8 debt and the trigger for returning below the prior 30m cap (.github/workflows/ci.yml:326-329), and the slow-test exemption records measurement plus paydown ownership (scripts/slow-test-exemptions.txt:70). I do not see new untracked scaffolds, TODOs, or temporary representations.

3. Verdict

APPROVE. The PR preserves the E5 descent boundary by documenting STOP/fail-closed behavior instead of sneaking in evaluator or substrate authority, and the CI/test-budget expansions are bounded with ratchet language rather than becoming silent debt. No blocking invariant issue appears in the changed lines.

  • Comparison: origin/main @ 8d88dcc3 ... review/pr-1799-04af5928 @ 04af5928
  • Thinking: 40s wall

Findings

No issues tied to the diff against INVARIANTS.md, docs/modeling-discipline.md, CODING.md, or TESTING.md.

  • Substrate / modeling: the only substantive addition is docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md, which records a STOP on LoopBound::Descent until a named proof authority exists—consistent with fail-closed (P3) and avoiding parallel evaluator-local proof authority (P2). No new substrate types or Rust mirrors appear in the diff.
  • Scaffolds / debt: CI changes in .github/workflows/ci.yml pair longer budgets with explicit ratchet-back language (Stage 2d 300→360s, self_host_ratchet 30→60m with a named “when … regularly completes under …” trigger). That matches the “tracked bridge” pattern the rubric expects for operational headroom, not silent relaxation.
  • Testing: scripts/slow-test-exemptions.txt adds one row with an owned paydown note; scripts/check-test-timeout.sh bumps the exemption ceiling in lockstep—same pattern as existing entries.

Verdict

APPROVE — The diff is narrow (brief + CI/test-infra tuning + a trivial cached_compile_to_dag import in integration.rs). Nothing in it clearly violates the referenced invariants or coding/testing discipline.

  • Thinking: 35s wall

The brief’s pointers match lib.rs (eval_loop, LoopBoundDescentResidual, focused tests). No rubric violations found in the diff.

Findings: None. The new STOP packet explicitly preserves fail-closed behavior for LoopBound::Descent, names a single resumption shape, and forbids parallel evaluator-local proof inference — consistent with P3 (Fail-Closed) and P2 (single authority) from INVARIANTS.md. CI and timeout script changes pair documented headroom with named ratchet-back triggers (Stage 2d budget, self-host job cap, exemption paydown), which matches the tracked scaffold / debt guidance in INVARIANTS.md / docs/modeling-discipline.md rather than silent slack. The slow-test exemption line follows the existing TESTING.md pattern (owner + paydown pointer). The integration.rs import tweak is neutral for CODING.md.

Verdict: APPROVE — The diff is narrowly scoped (brief + CI/test-timeout hygiene + one import cleanup), stays aligned with the modeling invariants for E5, and does not introduce substrate or evaluator behavior changes that would need deeper review here.

…S3∥S8 + demo as Acceptance bullets

Per Substrate Mgr partition response at gunbc#846 #issuecomment-4385074769.
Substrate Mgr provided clean trigger-state partition for §1 12 items + worker
pins + structural corrections.

Updates absorbed:

S7 PR-F: worker pin narrowed to loyal-wolf-828 (per Q-PR-F bandwidth-aware
routing + Substrate Mgr explicit partition); valiant-ant-72 reserved for S3
MachineConstraint<C> implementation post-design (cleaner separation of
authoring vs implementation phases).

S8 ApproximateField<F> Float migration: dispatch trigger updated from
"post-S3 (sequential) OR parallel" → "**parallel with S3**" per Substrate
Mgr correction. MachineConstraint<C> and ApproximateField<F> are
INDEPENDENT axes (machine width vs algebra approximation); both Mgr-tier
design now with cross-reference at brief-landing.

S10 T-E-P-Producer-Broadening: worker pin = quick-koi-190 (currently on
#1799 termination-contract; T-E-P consumes descent-evidence, natural
follow-on).

S11 Slice C: dispatch trigger refined to "post-#1795 (Slice A) + #1801
(Slice B) merge" cascade-clearance; worker pin = smart-ram-167 (Slice B
precedent owner; pattern-familiar).

5 demonstration gates (#67/#68/#70/#72/#73): per Substrate Mgr structural
correction — fold demonstration scope into parent worker brief Acceptance
bullets, NOT separate dispatches. Each gate becomes Acceptance bullet on
parent lane's brief.

Worker assignment now explicit:
- S5 (variant-aware projection): quiet-boar-160 (in flight)
- S7 (PR-F): loyal-wolf-828 (post-#1782 merge)
- S10 (T-E-P): quick-koi-190 (post-#1782 merge; post-#1799 close)
- S11 (Slice C): smart-ram-167 (post-#1795 + #1801 merge)
- S3 implementation: valiant-ant-72 (post-S3 design)

Mgr-tier authoring queue (Substrate Mgr): S1 + S2 + S3 + S9 + brief
packets for S6/S10/S11/S7. Surfaces ratification needs to PM/Director
queue as canvases land.

Net: §1 dispatch matrix now reflects Substrate Mgr's lane-knowledge
corrections. Substrate is the first Mgr to engage substantively with
the design schedule + provide partition response — exactly the pattern
the schedule was meant to enable (Mgrs partition + dispatch without
PM micro-management).

…; ALL 6 of 6 Mgrs engaged

Per Evaluator Mgr partition response at gunbc#846 #issuecomment-4385081532.
**Sixth and final Mgr to engage substantively** — all 6 of 6 R3 Mgrs now
have lane-specific worker partitions in design schedule.

§4 header carries Evaluator Mgr's worker partition table:
- E1 E6-G0d constructor execution: DISPATCHED 2026-05-06 to valiant-carp-10
  (#1767); evaluator-only src/v3/compiler/src/lib.rs; brief = #1784
- E2 E5 Descent termination contract consumer: HELD pending Substrate
  carrier landing (quick-koi/quick-crab path)
- E3 E6-G1.a static lens fold: HELD pending Director Q-PAFS /
  Q-EVAL-Lens-Fold-First-Slice countersignature
- E4 E6-G1.b generic dispatch: HELD post-G1.a + post-Substrate X1.b
- E5 X1.b S1 TransformDispatch coordination: DONE cross-lane status sent
  to Substrate (#1739)

Additional state notes:
- #1784 G0d brief green on fmt/ci/v3; self_host_ratchet in progress
  post-main merge — doesn't block E1 dispatch (brief stable + approved)
- #1799 E5 STOP packet green on fmt/ci/v3; held semantically behind
  Substrate termination contract
- warm-dove #1778 passing/held; existing PR needs Director/PM disposition

No PM/Director ratification needed for E1/E5. E3 still needs Director
countersignature.

Net: 6 of 6 Mgrs (Substrate / Verification / Debt-Paydown / PB / Grounding /
Evaluator) substantively engaged with design schedule. Concrete dispatches
in flight: G4 (silent-badger-711) + DP1 + DP2 (PR #1807) + E1 (valiant-
carp-10) + S5 (quiet-boar-160 in flight) + Substrate Mgr-tier authoring
queue (S1/S2/S3/S9). Cross-lane coord working: E5 → Substrate; G* → S*
trigger-cascade.

Engagement scoreboard: 100% of R3 Mgrs partitioned + dispatching per
schedule. PM micro-management overhead = zero per Mgr-tier dispatch
discipline.

  • Thinking: 17s wall

APPROVE — Docs + CI only. The PR adds an E5 STOP packet brief explaining why LoopBound::Descent execution remains deferred (fail-closed) until a termination-evidence authority is assigned, plus three small CI hygiene changes: lane2d cold-compile budget bump 300s→360s with a documented ratchet-back trigger, one new slow-test exemption (count 40→41) with paydown owner cited, and a trivial use cleanup in the t_demo fixture test module. No substrate, evaluator, parser, or lowerer code is touched, and the brief explicitly forbids the exact widenings/reinterpretations that would violate fail-closed and single-authority invariants. Findings: none.

Exploratory: the lane2d budget widening and the new exemption both carry named, bounded paydown triggers (fixture compile amortization; R3-V L4/L7 shared runner setup) — that's the tracked-debt shape the rubric asks for, so accept.

* docs(r3): comprehensive R3 design schedule — per-Mgr dispatch matrix per Brian directive

Per Brian directive 2026-05-06 (chat): "can we schedule all the design now?"

Authors `docs/r3-design-schedule-2026-05-06.md` — central PM-tier dispatch
matrix covering all 6 R3 Mgrs + cross-program / Director-tier decisions.

Per-Mgr design queue:

§1 Substrate Mgr (12 design items): Q-Class-2 gap-test (S1) + LBP scope-
calibration canvas (S2) + MachineConstraint<C> carrier (S3) + Workflow*
family (S4) + variant-aware projection (S5) + EmissionPathProjection (S6) +
PR-F (S7) + ApproximateField<F> Float migration (S8) + T-Numeric-
Construction brief (S9) + T-E-P-Producer-Broadening dispatch (S10) +
Slice C #1795 follow-up (S11) + F2/F8 doc-sharpening (S12) + 5
demonstration gates.

§2 Verification Mgr (7 design items): Pattern-A executable cluster (V1)
+ L4/L7 exhaustive coverage (V2) + T-Lens-Self-Application stronger demo
(V3) + T-Tests-As-Data lane work (V4) + T-Free-Consequences 10 gates (V5)
+ bridge_retirement_ledger_zero audit gate (V6) + ValueBody isomorphism
(V7).

§3 PB Mgr (5 design items): T-LensProducer-Retirement (P1) + T-FixedPoint
completion (P2) + T-V2-Retirement post-FP+LP (P3) + 3 PB-owned bridges
(P4) + F2/F8 cross-lane (P5) + 4 demonstration gates.

§4 Evaluator Mgr (5 design items): E6-G0d constructor execution (E1) +
E5 Descent termination contract (E2) + E6-G1.a static lens fold (E3) +
E6-G1.b generic dispatch (E4) + X1.b S1 coordination (E5).

§5 Grounding Mgr (5 design items): L6 row population (G1) + T-Ground-Rust
full coverage (G2) + Coercion-Fold scratch retirement (G3) + F10 cleanup
(G4) + Anthropic #1702 re-dispatch (G5).

§6 Debt-Paydown Mgr (5 design items): Q-Drift-Reconcile (DP1) + SG-0 CI
gate (DP2) + velocity tripwire (DP3) + closure-receipt cadence (DP4) +
#1566 rollup hygiene (DP5).

§7 Cross-program / Director-tier (5 decisions): Q-LBP-R3-Closeability
(CP1) + Q-Tier4-Inclusion (CP2) + Q-WEDGE-A framing (CP3) + Q-Class-6
(CP4) + PR #1794 merge (CP5).

§8 Sequencing summary: critical path (T-E-P-Producer-Broadening → T-LBP →
T-LAS||T-WAD → T-LSA) + parallel longest single-lane (T-V2-Retirement) +
Verification-internal path + bottleneck escalations.

§9 Status update cadence: daily Mgr-internal + weekly Mon/Wed/Fri PM
compilation. Cross-Mgr coord via Director queue.

§10 References: r3-structure.md / r3-program-plan.md (incl. §1.8 ledger) /
audit/r3-debt-sweep-2026-05-06.md / 6 Mgr inboxes + Director + Research
PM.

Total design items: ~44 across 6 Mgrs + 5 Director-tier decisions.

Net: per-lane Mgr design work scheduled in parallel with Brian/Director
scope-calibration decisions. Mgrs do NOT wait for all decisions to
resolve — design dispatches in flight as escalations resolve.

§2.2 sequencing authority RATIFIED as HARD DAG (PM disposition 2026-05-06):
Per PB Mgr's surface — "staffing parallelism vs hard DAG" question
explicitly resolved. r3-structure.md §"Lane structure" → T-FixedPoint row
names "R2-close dependency: SG-0 zero from T-LensProducer-Retirement" as
explicit dependency. SG-0 zero is structural precondition for T-FixedPoint
(bit-identical compile requires no remaining hand-Rust ratchet); not just
resource sequencing.

T-FixedPoint cannot complete until T-LP-Retirement completes. Plan §2.2
sequence is canonical authority on this; PB Mgr's HOLD on P2 is correct
discipline.

Net: 4 of 6 Mgrs (Substrate + Verification + Debt-Paydown + PB) engaged

- E4 E6-G1.b generic dispatch: HELD post-G1.a + post-Substrate X1.b
- E5 X1.b S1 TransformDispatch coordination: DONE cross-lane status sent
  to Substrate (#1739)

Additional state notes:
- #1784 G0d brief green on fmt/ci/v3; self_host_ratchet in progress
  post-main merge — doesn't block E1 dispatch (brief stable + approved)
- #1799 E5 STOP packet green on fmt/ci/v3; held semantically behind
  Substrate termination contract
- warm-dove #1778 passing/held; existing PR needs Director/PM disposition

No PM/Director ratification needed for E1/E5. E3 still needs Director
countersignature.

Net: 6 of 6 Mgrs (Substrate / Verification / Debt-Paydown / PB / Grounding /
Evaluator) substantively engaged with design schedule. Concrete dispatches
in flight: G4 (silent-badger-711) + DP1 + DP2 (PR #1807) + E1 (valiant-
carp-10) + S5 (quiet-boar-160 in flight) + Substrate Mgr-tier authoring
queue (S1/S2/S3/S9). Cross-lane coord working: E5 → Substrate; G* → S*
trigger-cascade.

Engagement scoreboard: 100% of R3 Mgrs partitioned + dispatching per
schedule. PM micro-management overhead = zero per Mgr-tier dispatch
discipline.

* docs(r3): codex BLOCKING fixes — §S4 audit-first against extdeps.github.actions + §V1 Pattern-A 5th gate routed to T-CostLens

Fix 2 of 4 codex BLOCKING findings on PR #1810:

1. §S4 Workflow* family carriers (Class 4) — prepend existing-ontology audit
   prerequisite citing dsl/extdeps/github/actions.dag (218 lines, already
   declares Workflow / WorkflowTrigger / Job / Step / MatrixStrategy /
   RunnerSpec / WorkflowPermissions / ConcurrencySpec / DispatchInput).
   Reframe proposed carriers as audit targets / deltas, not fresh ontology;
   require Substrate Mgr audit-and-delta receipt before worker dispatch.
   Per feedback_audit_adjacent_authority_first + feedback_parallel_representation_debt.

2. §V1 Pattern-A executable cluster — fix count mismatch. Headline now says
   "4 NEW (DimensionReport-typed cluster) in V1"; explicit note that the 5th
   NEW Pattern-A gate (§1.8 #40 symbolic_cost_expr_equals_executable,
   SymbolicCost-typed) belongs to T-CostLens-Composition lane, not V1's TC
   cluster (per r3-program-plan.md:755 — different predicate family,
   distinct runner work). Closure-predicate citation updated accordingly.

Findings 1 (external PM ledger) + 2 (Mgr-canvas → lane authority) rebutted
on PR with grep evidence — both invalid.

Non-blocking — Strengths

  • docs/briefs/r3-pr-e5-loopbound-descent-stop-packet.md The STOP packet matches the live LoopBound::Descent { cluster, measure } substrate and keeps execution fail-closed until a single termination-evidence authority exists.
  • .github/workflows/ci.yml The Stage 2d budget increase is bounded and carries a named ratchet-back trigger, so it is tracked CI headroom rather than silent debt.
  • scripts/slow-test-exemptions.txt The added slow-test exemption names the observed timing and paydown owner while the ratchet count is updated consistently.

✅ Mixed docs/CI/test PR looks clean; no blocking concerns.

Consume the substrate descent_execution_proof carrier at LoopBound::Descent evaluation, threading the DescentExecutionProof through obligation discharge and preserving fail-closed LoopBoundDescentResidual mapping for gamma residuals.

Adds co-located evaluator tests for strict per-path proof success plus EvidenceIncomplete, EvidenceUnknown(NonIncreasing), and EvidenceUnknown(DescentUnknown) fail-closed cases.
