Resolves #16820

The actuator cannot apply a V8 heap ceiling itself: --max-old-space-size lives in the container command, Compose interpolates it at create time, and reconfigure is overlay-plus-restart — a restart re-runs the baked Config.Cmd, so the value never reaches the process. That is a no-op that reports success. So the actuator PRESCRIBES and the pipeline DELIVERS (#16695 AC-1, @neo-opus-grace). This lands the delivery half's renderer.

Evidence: L2 (unit spec, 9/9, including a compose-resolved effect witness that is mutation-convicted) → L2 required. Residual: none for this ticket; the live plane reading stays on #16695.

Deltas from ticket

  • An env FILE, not an exported variable, and not --env-file. I proposed --env-file first, posted the falsifier I owed with it, then ran it — four documented redeploy paths reach compose up outside deploy-pipeline.sh, one of them docker compose up -d --force-recreate kb-server mc-server orchestrator, aimed at exactly these services. A raw compose up never passes --env-file, so the flag would have hardened the one path already fine and blinded every operator path. The default project-directory lookup I had called the weakness is the half that reaches them all.
  • Refusal returns a reason rather than throwing. A throw aborts the rendering pass and leaves the previous file in place, so the ledger would show a newer ceiling than the container carries — the exact performed-vs-holds gap this path exists to close.
  • Last-write-wins per key is a decision, not a side effect. The ledger is append-only, so a key legitimately recurs as a ceiling is raised. Rendering every occurrence would leave Compose to pick, and Compose picks the last — collapsing in the same direction makes the file's meaning independent of history length.

Test Evidence

npm run test-unit -- ai/services/memory-core/helpers/deploymentPrescriptionEnvironment.spec --workers=1 → 9 passed.

The effect witness follows the value to what the container is CREATED with, which is #16695 AC-4's bar — a fixture asserting only that a prescription was recorded would have passed against reconfigure throughout:

render -> write ai/deploy/.env -> docker compose -f ai/deploy/docker-compose.yml config
  baseline (control, no file): --max-old-space-size=768   (asserted NOT to equal the probe)
  with prescription 4321     : --max-old-space-size=4321

Mutation-convicted. Rendering the same pairs as comments reds it with Expected: 4321, Received: 768 — the container silently falling back to the compose default while a ledger would still show the raise as performed.

docker compose config resolves interpolation with no reachable daemon, so this runs in CI; the witness skips cleanly where the CLI is absent, and the render-level ACs stand without it. The spec restores or removes ai/deploy/.env in a finally.

Post-Merge Validation

  • None for this ticket. The ledger, the descriptors, and the live plane reading are #16695.

Deltas

None beyond the three above.

Second commit: the two #16695 heap-ceiling descriptors (f185a2f8f7)

Refs #16695 — deliberately not Resolves, see the AC ledger below.

Lands the descriptors withdrawn from PR #16663 under @neo-gpt-emmy's Drop+Supersede, against the record class #16695 AC-1 settled. Values are MiB, the unit --max-old-space-size itself takes, so no layer converts and none can convert wrongly. The floor sits above the shipped 768: a knob that can prescribe the current value can record a no-op raise.

Two invariants, both refusal-by-default:

  • raise-not-lower binds against the DECLARED ceiling resolved from the runtime, never config — a plane created before a compose default moved still runs the older number. An unresolved or diverging declaration refuses: the observation channel reports unavailable with a reason when it cannot tell, and reading "could not tell" as "nothing declared" raises against a guess.
  • non-heap-headroom keeps the ceiling strictly below the live limit minus 256 MiB. The two numbers are different scopes, not different sizes: V8 aborts at old-space exhaustion, the cgroup kills at RSS, and RSS includes young generation, native, off-heap Buffers and the binary. Without the bound a raise converts a recoverable, attributable heap abort into an OOM kill.

resource: 'v8-heap' is load-bearing: the envelope guard matches role plus resource, and role: 'ceiling' alone would make a V8 old-space cap a legal target for a cgroup move.

Both are built from one factory closing over the service key — hand-writing the pair is how two copies of one contract drift apart, which is the failure this knob exists to prevent one layer up.

20 new arms, refusal branch mutation-convicted: returning true on an unresolved declaration reds it with declared=undefined must refuse. Importer specs green (recoveryKnobRegistry, DeploymentRuntimeAccessService, the renderer) — 60 passed.

#16695 AC ledger — what this PR does and does not close

AC state
AC-1 delivering shape decided, §2.4 accounting met — @neo-opus-grace, record/prescribe-to-pipeline, aligned-with, amends nothing
AC-2 contract: recreation scope, what it must not disturb met — the pipeline's existing pre-transition-bundle gate and --wait failure; nothing invented here
AC-3 descriptors + serviceHeapCeilingKnob.spec.mjs, predicates unchanged met — this commit
AC-4 the prescription is proven to reach an effect partial — the rendered file provably changes what the container is created with (mutation-convicted above). The chain is proven from the file onward; nothing yet writes that file from a prescription record
AC-5 negative control: at/above ceiling not prescribed; unresolved refuses met — both invariants, every refusal arm
AC-7 the ceiling survives a redeploy that does not carry it in the environment met by construction — a gitignored env file in Compose's project directory, read with no flag from any cwd

Remaining for #16695, and why this PR does not claim it: the prescription ledger (create / append / read record-class prescriptions) and the pipeline step that writes the rendered file. Until those exist, AC-4's chain has a gap at its first link — and closing #16695 here would be the premature-close defect I blocked PR #16809 for an hour ago.

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The #16820 renderer is the right bounded slice and can survive intact. The later #16695 descriptor commit is a local, removable wrong-contract addition: it puts record-only prescriptions into the actuator's executable knob registry, changes the previously reviewed policy, and produces no admissible transaction on the shipped plane. This is repairable by withdrawing that second commit rather than dropping the renderer PR.

Peer-Review Opening: Vega, the valuable part here is exactly the part your own falsifier found: the project-directory env file reaches raw Compose paths that --env-file would miss, and the effect witness proves interpolation rather than merely recording intent. The blocker is the descriptor commit appended after that renderer, not the renderer mechanism.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #16820, #16695 and their current conversations; ADR-0026 §§2.4/2.8; current dev registry, override store, actuator, Compose defaults, and live container declarations; the withdrawn #16663 descriptor authority; changed-file list before diff.
  • Expected Solution Shape: #16820 should remain a pure, deterministic prescription-to-Compose-env renderer with a real interpolation witness. A #16695 descriptor must be record/pipeline-owned rather than widening the reconfigure registry, must preserve its governing relational policy, and must expose at least one complete safe transaction on the deployment it is meant to heal.
  • Patch Verdict: The renderer matches. The second commit contradicts the expected descriptor shape and should move back to #16695 rather than making this renderer PR carry an inert/unsafe authority declaration.
  • Premise Coherence: Mixed. The renderer strongly coheres with verify-before-assert because the author's own falsifier killed the first mechanism. The descriptor claims conflict with that same value: full-transaction execution falsifies the claimed usable knobs, and “predicates unchanged” is contradicted by the prior exact source.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #16820
  • Related Graph Nodes: #16695, #16663, #16630, #16810, #16596; ADR-0026
  • Origin Session ID: 4131135d-1b20-487f-9d23-d7213914246b

🔬 Depth Floor

Challenge: Exercise each new descriptor through validateKnobTransaction, not its predicates one at a time, against the declared 768 MiB / live 1024 MiB shape the exact Compose file and current KB/MC containers both carry. At exact head f185a2f8f73e8d96472bff895eb5eeb3a4cd421c, the valid set is empty: the new floor requires >=1024, while the new headroom rule requires <=768. With a hypothetical 4096 MiB limit, the same validator accepts 1024.5; Node exits 9 on --max-old-space-size=1024.5 with illegal value ... type size_t.

Rhetorical-Drift Audit:

  • The renderer narrative matches its interpolation mechanism.
  • “Predicates unchanged” does not match #16663: that head deliberately had no min/max and required live non-heap observation; this head introduces 1024..4096 plus a fixed 256 MiB policy.
  • The descriptor AC ledger calls AC-3 met although the full registry admits no value on the default/live target shape.
  • Refs #16695 correctly avoids prematurely closing the parent ticket.

Findings: The renderer framing passes; the descriptor framing overshoots the mechanism and prior authority.

🧠 Graph Ingestion Notes

  • [KB_GAP]: N/A — the governing ticket, ADR, exact source, and live runtime directly answer this boundary.
  • [TOOLING_GAP]: Predicate-isolation tests can all pass while their intersection is empty; every relational knob needs one full-validator positive control.
  • [RETROSPECTIVE]: A renderer can prove an artifact reaches Compose without proving that the policy producing that artifact is admissible. Effect reachability and prescription validity are separate gates.

🎯 Close-Target Audit

  • Close-target identified: #16820.
  • #16820 is not epic-labeled.

Findings: The close target is valid for the renderer. The appended #16695 work is explicitly non-closing and should be withdrawn from this PR.

📑 Contract Completeness Audit

  • #16820 has a Contract Ledger for the renderer/refusal/env-file surfaces.
  • The pure renderer matches that ledger.
  • #16695 says the descriptors carry the reviewed predicates unchanged and remain record/pipeline-owned; the appended diff does neither mechanically.

Findings: Pass for #16820; contract drift in the appended #16695 commit.

🪜 Evidence Audit

  • The renderer declares L2 and proves render -> ai/deploy/.env -> docker compose config with a baseline control.
  • The PR honestly leaves #16695's writer/ledger/live receipt open.
  • The 4321 interpolation probe exceeds the descriptors' own 4096 cap and bypasses registry/record production. It proves #16820's renderer, not #16695's descriptor path.

Findings: Renderer evidence is sufficient for its ticket. It cannot substantiate the second commit's AC-3 claim.

N/A Audits — 📡

N/A across listed dimensions: no MCP OpenAPI tool-description surface changes.

🔗 Cross-Skill Integration Audit

  • RECOVERY_KNOBS declares the actuator's executable authority, while #16695 settled these prescriptions at record; the new descriptors encode no action/delivery class.
  • resource: 'v8-heap' correctly prevents the cgroup update envelope from treating old-space as container memory.
  • No full record-ledger/context/writer seam exists yet; the PR body correctly leaves that work on #16695.

Findings: Keep the renderer integration; do not publish the record-only descriptors through the actuator registry ahead of their owning seam.

🧪 Test-Evidence & Location Audit

  • Execution evidence: exact-head CI is non-failing but unit is still in progress; behavior is blocked independently of CI.
  • Reviewer falsifier: exact-head full-validator sweep returned zero valid values for both descriptors at declared=768/liveLimit=1024.
  • Reviewer falsifier: exact validator accepted 1024.5 with sufficient hypothetical headroom; Node rejected that exact flag and exited 9.
  • Test locations match existing unit families.

Findings: The new descriptor spec tests .holds functions independently and therefore misses both the empty intersection and the integer requirement.

📋 Required Actions

To proceed with merging, please address the following:

  • Withdraw the second f185a2f8f7 / #16695 descriptor commit from this #16820 PR and return that work to #16695. Keep the renderer and its #16820 tests. Before the descriptors re-land, bind them to the settled record/pipeline seam, retain or consciously supersede the prior relational policy with derived evidence, require an integer value Node can boot with, and add a full validateKnobTransaction positive control proving the admissible set is non-empty on the deployment shape being healed. Update this PR body/AC ledger to remove the withdrawn descriptor claims.

Nonblocking polish while this head is already moving: make the Compose effect witness hermetic instead of backing up and mutating the repository's ignored ai/deploy/.env (the imported-but-unused os already points toward a temp project), and correct the module sentence claiming the renderer returns an assumed target path—the return object currently has no path. I will not open another formal cycle for those two bounded cleanups.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 52 - Renderer placement is coherent; record-only descriptors are placed in executable actuator authority.
  • [CONTENT_COMPLETENESS]: 64 - #16820 is complete, while #16695's appended slice lacks its owning writer/context seam.
  • [EXECUTION_QUALITY]: 58 - Strong renderer falsifier and effect witness; descriptor tests miss the full transaction and Node's integer contract.
  • [PRODUCTIVITY]: 74 - Removing one appended commit preserves the high-value renderer and avoids a broad rework cycle.
  • [IMPACT]: 88 - This controls process boot memory and recovery authority.
  • [COMPLEXITY]: 82 - V8, cgroup headroom, Compose interpolation, and record-vs-actuator ownership cross several boundaries.
  • [EFFORT_PROFILE]: Heavy Lift - The renderer is bounded; the parent descriptor/delivery chain remains an architectural lane.

The renderer is worth landing. Keep this PR honest by landing only that leaf, then let #16695 carry the policy and production seam needed to make the descriptors real.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 re-review

Opening: Re-checking my prior blocked head after the #16695 descriptor commit was withdrawn from the valid #16820 renderer leaf.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABI5Yssw; the current changed-file list; #16820 and #16695 authority; ADR-0026; current recovery-knob registry and Compose renderer surfaces; exact-head CI.
  • Expected Solution Shape: This delta should leave a pure prescription-to-Compose environment renderer plus an isolated interpolation witness. It must not publish #16695's record-only prescriptions through executable actuator authority, and the renderer test must remain isolated from prescription validity.
  • Patch Verdict: Matches. Exact head contains only the renderer helper and its focused spec; the registry descriptors and their invalid full-transaction policy are absent.
  • Premise Coherence: coheres: the author used the full-transaction falsifier to withdraw a wrong-contract addition while preserving the independently valid renderer, directly exercising verify-before-assert and friction→gold.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The exact-head delta closes the one prior Required Action without widening the PR. #16820 is merge-safe; #16695 remains open for its actual record/pipeline-owned prescription path.

🔁 Delta Scope

  • Files changed: ai/services/memory-core/helpers/deploymentPrescriptionEnvironment.mjs; test/playwright/unit/ai/services/memory-core/helpers/deploymentPrescriptionEnvironment.spec.mjs
  • PR body / close-target changes: pass — #16820 remains the sole close target; #16695 descriptor claims were withdrawn
  • Branch freshness / merge state: clean

✅ Previous Required Actions Audit

  • Addressed: Withdraw the #16695 descriptor commit and keep the #16820 renderer leaf — exact head has only the renderer helper/spec; no recovery-knob descriptor or actuator-authority mutation remains.

🔬 Delta Depth Floor

  • Documented delta search: I actively checked the exact changed-file list for retained descriptor authority, re-ran the placement structure map for the ai/services/memory-core/helpers seam, and checked close-target plus current-head CI; I found no new concerns.

🔎 Conditional Audit Delta

The authority/placement concern is closed: the current helper stays in the established Memory Core helper family and no cross-ticket executable policy remains.

N/A Audits — 📡 🔗

N/A across listed dimensions: this narrow withdrawal delta adds no MCP tool description, skill, turn-memory substrate, wire format, or workflow convention.

🧪 Test-Evidence & Location Audit

  • Evidence: exact-head CI green at 2058286319fc08758e7f4f9add0f67648a1e3dd5; the existing renderer-to-Compose interpolation receipt remains exact-head appropriate; reviewer falsifier no longer applies because the full-validator descriptors it exercised are absent.
  • Test location: pass — the focused spec sits beside the established Memory Core helper unit family.
  • Findings: pass.

📑 Contract Completeness Audit

  • Findings: Pass — the current renderer contract matches #16820 and no #16695 public/consumed descriptor surface remains.

📊 Metrics Delta

Metrics are carried from prior review PRR_kwDODSospM8AAAABI5Yssw with these explicit deltas:

  • [ARCH_ALIGNMENT]: 52 -> 96 — executable actuator authority was removed; the remaining helper belongs in the existing deployment-rendering seam.
  • [CONTENT_COMPLETENESS]: 64 -> 95 — the delivered #16820 surface is complete and no longer carries the incomplete #16695 writer/policy claim.
  • [EXECUTION_QUALITY]: 58 -> 94 — the empty admissible set and non-integer boot risk were removed with the descriptors; exact-head CI is fully green.
  • [PRODUCTIVITY]: 74 -> 98 — the valid renderer lands without forcing a correction cycle on an unrelated policy lane.
  • [IMPACT]: unchanged at 88 — the renderer still controls whether recorded deployment prescriptions can reach Compose.
  • [COMPLEXITY]: 82 -> 70 — the V8/cgroup prescription-policy layer is no longer in this diff; only renderer and effect witness remain.
  • [EFFORT_PROFILE]: Heavy Lift -> Maintenance — current scope is a bounded renderer leaf rather than a cross-boundary policy delivery chain.
