 The first-party eBPF agent is now the **sole deployed** corroboration source. The port it
 feeds remains open to any sensor; only the Falco-specific adapter and the cancelled-bake
 measurement are gone.
+
+## Amendment (2026-08-08): baked offsets are the decided posture; a load-time BTF preflight replaces manual re-verification
+
+The agent's eBPF bindings hand-lay kernel struct offsets (verified at kernel 7.0.0) rather
+than relocating them via CO-RE. **The original CO-RE language was aspirational: rustc cannot
+emit BTF field relocations** (`preserve_access_index` is a pending Rust RFC; bpf-linker emits
+func_info BTF for fentry attach but not field-access relocations), so the agent bakes
+hand-verified offsets. The `offset_of!` guard catches an inconsistent *edit* but not a
+correct-looking layout that is *wrong for a new kernel* — and a stale
+`bpf_probe_read_kernel` offset reads **garbage silently**, feeding wrong corroboration
+signals into the action bar (only the `bpf_d_path` reads are verifier-checked).
+
+**The durable guard is a userspace load-time preflight.** Before attach, the loader verifies
+every baked field offset and BTF-visible enum value (`LOADING_MODULE`) against the node's
+**live BTF** (the same BTF it already reads for fentry attach). On mismatch it attaches only
+the struct-free probes (connect/ptrace/module-load), logs each divergent field
+(expected-vs-actual — the data needed to update the bindings), and reports degraded via the
+existing heartbeat — never crash-loops (degrade-gracefully). A kernel bump can move a field
+but can never silently ship wrong reads. Offsets live in **one place** — a const table in
+`agent/common`: the eBPF crate's `offset_of!` asserts `bindings == table` at compile time;
+the loader asserts `table == node-BTF` at load; transitively `bindings == kernel`. No
+`PROTECTOR_*` toggle (a correctness guard, not a feature).
+
+**Build-time binding generation was considered and rejected** — it bakes the *builder*
+kernel's offsets, which diverge from node kernels exactly during a rolling upgrade (the event
+this defends against), and cannot run off-fleet. **Real CO-RE is the recorded end state**:
+when the Rust toolchain can emit BTF field relocations, the preflight retires with the baked
+offsets. Any comments claiming the object is "CO-RE-relocated against node BTF at load" are
+corrected to reflect this — baked offsets + a load-time BTF check, not relocation. See
+`docs/ideas/ebpf-offset-self-verification.md`.

+## Addendum (2026-08-08): apply-side scope confinement; no in-product approve-to-apply
+
+§5's "human approval" is pinned down: **protector never grows an in-product approve→apply
+path for node containment.** Every operator-reachable surface is read-only by decision
+([ADR-0016](0016-severity-vs-urgency.md): presentation is a view, never a decision gate;
+[ADR-0031](0031-read-only-mcp-server-tiered-redaction.md): the MCP is read-only), and an
+approval control would be exactly the view-becomes-gate shape those ADRs refuse. The durable
+act stays where §4 put it — a human, out of band (cordon + runbook). The actuator's `apply`
+glue remains in-tree, tested in isolation; any future in-product flow requires its own ADR.
+This retires "the future apply call-site" as a design location.
+
+Consequently the `enforceScope` confinement of the co-resident deny sweep lives at the
+**actuation boundary**, not a hypothetical apply flow: the shared full-set sweep stays
+unfiltered (the revert path must lift *every* deny protector could ever have placed —
+filtering revert would orphan out-of-scope denies), while the **apply-facing subset — the
+only set `apply` accepts, by type (a `ScopedDenies` newtype)** — and the proposal-side
+eligibility check (`contain_node_in_scope`) both derive from the same
+[ADR-0021](0021-two-setting-operating-posture.md) scope match the webhook uses. Unscoped =
+full set; scoped = only in-scope co-residents are denied, and the containment is honestly
+**weaker**: out-of-scope pods on a contained node stay reachable, because a deny written into
+an unauthorized namespace is the enforce-everywhere escape ADR-0021 exists to prevent
+(filter, don't refuse-whole). The model-visible fixed proposal note is unchanged — the model
+decides *what*; `enforceScope` governs *where-authorized*. See
+`docs/ideas/containnode-scope-confinement.md`.

+# Idea brief — Close the ContainNode enforceScope escape at the actuation boundary
+
+**Status:** settled → ticketed (unblocks the deferred co-resident-deny scope-filter). Load-bearing decision recorded as an
+addendum to [ADR-0040](../adr/0040-node-scoped-containment-mechanism-escalation.md).
+
+## The idea (as posed)
+Unblock the deferred scope-filter for node containment: `co_resident_denies`
+(`engine/src/engine/respond/actuator/node_containment.rs`) returns one default-deny per
+labelled pod co-resident on a contained node, **unfiltered by `enforceScope`**. Applying it
+unfiltered would write default-deny `NetworkPolicy`s into namespaces the operator never
+authorized — the enforce-everywhere escape [ADR-0021](../adr/0021-two-setting-operating-posture.md)
+exists to prevent. The fix was deferred to "the future apply call-site," and the #324 review
+ruled the shared helper must **not** be filtered (the revert path uses the full set; filtering
+it would orphan out-of-scope denies).
+
+## Two findings that reframe the unblock
+1. **The "apply call-site" will never exist on the current trajectory.** Protector has *no*
+   approve→apply mechanism for *any* action class: the dashboard is a view that never gates
+   ([ADR-0016](../adr/0016-severity-vs-urgency.md)), the MCP is read-only by ADR
+   ([ADR-0031](../adr/0031-read-only-mcp-server-tiered-redaction.md)), and `Decision::Propose`
+   terminates in a log line. "Human approval" has always meant *the human acts out-of-band
+   (kubectl)*. `NodeContainmentActuator::apply` is documented as having no `Engine` call site.
+   Waiting for that call site is waiting forever.
+2. **The deny set is not rendered anywhere** (grepped every surface). The `ContainNode`
+   proposal an operator reads is the menu line + a *fixed-string* note (no names, no counts);
+   the pre-arm scope preview *excludes* `ContainNode` (it requires `is_additive_live()`);
+   nothing enumerates the co-resident denies. So there is no "misrepresenting render" to fix
+   — the set's only non-test consumers are `contain_node_in_scope` (eligibility, already
+   scope-aware), the revert seam (full set, must stay), and the caller-less `apply`.
+
+## Recommended approach — scoped-subset function + newtype at the actuator seam
+Add `co_resident_denies_in_scope(graph, host, scope)` beside the unfiltered helper: unscoped →
+full set (historical meaning); scoped → retain denies where `scope.in_scope(deny)` holds (the
+same ADR-0021 namespace-OR-label match the webhook uses). Wrap its result in a `ScopedDenies`
+newtype constructible only by that function; change `NodeContainmentActuator::apply` to accept
+`&ScopedDenies` (revert keeps `&[Mitigation]`, full set). Rebase `contain_node_in_scope` on the
+same function so eligibility and the apply subset are **one scope-match source**, exercised
+every pass — the filter is live code, not dead insurance. This makes the invariant structural
+("safe by construction, not caller discipline" — mirroring the revert seam's own ownership
+gate): the only door into `apply` demands a scope-confined set *by type*, the revert path is
+untouched (per #324), and eligibility stops being a parallel scope implementation.
+
+Approaches rejected: **enumerate + filter the deny set on operator surfaces** (filters a view
+that doesn't exist and doesn't close the actuation escape — ADR-0016 says the view is never the
+gate); **build the approve-to-apply flow** (a mutating authenticated surface on a
+deliberately-read-only product — contradicts ADR-0016/0031; needs its own ADR if ever wanted).
+
+## Key decisions (see the [ADR-0040](../adr/0040-node-scoped-containment-mechanism-escalation.md) addendum)
+1. **No in-product approve→apply path for node containment** — the human act stays out-of-band
+   (kubectl cordon + runbook). This retires "the future apply call-site" as a design location.
+2. **Scoped apply is honest partial containment** — out-of-scope pods on a contained node stay
+   reachable, because writing into an unauthorized namespace *is* the ADR-0021 escape. Filter,
+   don't refuse-whole (consistent with the actuator's "partial containment is safer than none").
+3. **Filter home:** a sibling pure function + newtype at the actuator seam; the shared full-set
+   helper is untouched (revert semantics preserved).
+4. **`contain_node_in_scope` derives from the same subset function** — one scope-match source.
+5. **The model-visible fixed note is NOT amended** — encoding deployment scope into it would
+   churn the prompt fingerprint for information the model has no business weighing (the model
+   decides *what*, `enforceScope` governs *where-authorized*).
+
+## Risks / open items
+- Full-set revert vs filtered apply asymmetry is **safe**: revert deletes only protector-named
+  objects, so lifting a never-placed deny is a harmless no-op. Invariant: the revert set ⊇ any
+  set apply could have placed under any historical scope. Holds by construction.
+- Scope changed between passes: the subset is computed fresh at each call site from current
+  scope — no stored stale set.
+- Genuinely open: none. Pure-function change with exhaustive unit coverage.
+
+## HANDOFF TO PLAN-SPRINT
+Theme: **"close the ContainNode enforceScope escape at the actuation boundary + record the
+no-in-product-approve decision."** One small pure-function engine PR: `co_resident_denies_in_scope`
++ `ScopedDenies` newtype + `apply` takes the scoped set by type + rebase `contain_node_in_scope`
++ the ADR-0040 addendum. No chart/RBAC/config/dashboard surface. The deferred scope-filter ticket closes against it.
+Panel: infra.

+# Idea brief — eBPF offset self-verification (load-time BTF preflight)
+
+**Status:** settled → ticketed. Load-bearing decision recorded as an amendment to
+[ADR-0014](../adr/0014-behavioral-telemetry-ebpf.md).
+
+## The idea (as posed)
+Eliminate the agent's **manual eBPF struct-offset maintenance**. The eBPF crate
+(`agent/protector-agent-ebpf/src/vmlinux.rs`) hand-lays kernel structs so its field reads
+sit at verified kernel-7.0.0 byte offsets, with an `offset_of!` const block as a guard. The
+ticket proposed either **real CO-RE** (`preserve_access_index` BTF field relocation) or
+**build-time binding generation** from node BTF.
+
+## The problem, sharpened
+The `offset_of!` guard catches an *inconsistent edit* but not a *correct-looking layout that
+is wrong for a new kernel*. And the failure modes are worse than "a probe fails to load":
+only the `bpf_d_path(&file->f_path)` reads are verifier-checked against kernel BTF (they fail
+as `loaded=N<6`); every `bpf_probe_read_kernel` chase (`i_nlink`, `s_magic`, `uid.val`,
+`i_ino`, `d_name.name`, `linux_binprm.file`) at a stale offset **silently reads garbage** —
+feeding *wrong corroboration signals* (anon-inode exec, tmpfs secret-read, priv-change) into
+the action bar. The 6.8→6.11 `struct file` reorg already bit once (`loaded=4/6` fleet-wide),
+and two offsets + one enum value are still marked ON-NODE-PENDING in the tree. The fleet is
+homogeneous kernel 7.0.0 today, so the risk is **latent** — it bites on the next kernel bump
+or a new arch.
+
+## Assumptions corrected
+- **"aya gives us CO-RE" — false.** rustc cannot emit BTF field relocations for Rust struct
+  accesses; the `preserve_access_index` intrinsics are a pending Rust RFC (rust-lang/rfcs#3966).
+  bpf-linker emits BTF func_info (which is why fentry attach works) but **not** field-access
+  relocations. So CO-RE is blocked *upstream*, not a choice we can make today.
+- **"Build-time codegen removes the maintenance" — shaky.** It moves the offset bake from a
+  human to the *builder node's* kernel and silently assumes builder-kernel == every
+  node-kernel — which breaks precisely during a rolling kernel upgrade, the exact event this
+  work defends against. It also can't run off-fleet (dev/macOS, generic CI), so a checked-in
+  fallback survives anyway. It automates the ritual without closing the gap.
+- **Dangerous doc-rot found:** `agent/Dockerfile`, `.github/workflows/agent.yml`, and
+  `docs/ebpf-testing-on-nodes.md` claim the object is "CO-RE-relocated against the node's BTF
+  at load." That is **factually wrong** — `vmlinux.rs` is the only honest doc. The false
+  claim invites exactly the complacency this work exists to prevent; correct it.
+
+## Recommended approach — load-time BTF preflight (keep hand bindings; re-prove them at load)
+Keep the curated hand bindings, but before attach the userspace loader verifies each
+`(struct, field, expected-offset)` and the `LOADING_MODULE` enum value against the node's
+**live BTF** (the loader already reads `aya::Btf::from_sys_fs()` for fentry attach). On
+mismatch: log expected-vs-actual per field (the log *is* the regeneration data), attach only
+the struct-free probes (connect/ptrace/module-load), and surface degraded via the existing
+heartbeat/`probes_loaded`. This is the only option that checks offsets against **the kernel
+the probes actually run on**, per-node — so even a heterogeneous mid-upgrade fleet degrades
+honestly node-by-node. It converts "silent garbage reads / mystery `loaded=4/6` → human SSH
+session" into "the agent log names the exact field, its expected offset, and the kernel's
+actual offset." It is also the continuous on-node verification the two PENDING offsets need.
+
+Approaches rejected: **CO-RE** (blocked upstream — recorded as the *successor* end state for
+when the Rust toolchain lands field relocations); **build-time codegen** (bakes the builder
+kernel's offsets — automates the wrong thing).
+
+## Key decisions (see the [ADR-0014](../adr/0014-behavioral-telemetry-ebpf.md) amendment)
+1. **Single source of truth:** a const offset+enum table in `agent/common` (shared `no_std`).
+   The eBPF crate's `offset_of!` consts assert `bindings == table` at compile time; the loader
+   asserts `table == node-BTF` at load time; transitively `bindings == kernel`. No number lives
+   in two places.
+2. **Fail-closed on struct-reading probes, fail-open on scalar-only probes.** A mismatched
+   field disables the probes that read structs; connect/ptrace/module-load still attach. The
+   agent never crash-loops on mismatch — it stays up to report (ADR-0014 degrade-gracefully).
+3. **Include the enum check** (`LOADING_MODULE`) — the one constant that is a silent
+   misclassification today with no verifier backstop.
+4. **No toggle** (correctness guard, not a feature — repo convention).
+5. **CO-RE is the recorded successor**, revisited when rustc emits BTF field relocations; the
+   preflight then retires with the baked offsets. **Build-time codegen is rejected.**
+6. **Correct the stale "CO-RE-relocated at load" comments** in the same change.
+
+## Risks / open items
+- aya 0.13 `Btf` API surface for member iteration — worst case a small direct parse of
+  `/sys/kernel/btf/vmlinux` (aya-obj is already in the tree). Bounded; settled in the first
+  hour of building.
+- Anonymous-union members (`i_nlink`): the BTF walk must recurse into anon unions/structs
+  accumulating offsets — unit-tested against a fixture BTF blob (plain userspace Rust,
+  off-fleet testable).
+- The preflight validates *offsets*, not *semantics* (a field whose meaning changes at the
+  same offset slips through) — accepted; nothing short of CO-RE + kernel review fixes that.
+- Agent-workspace CI is not a required check (known blind spot) — the guard is runtime so it
+  doesn't depend on CI; flag making the ebpf job required as adjacent.
