Why: The Dev combination must test the gate narrowing, fact checks and lazy
search registration.
Evidence: SELF - gitlink equals backend feature/agent-quality-phase05 head.
Impact: Pointer only.
Why: establish the authorized task workspace and its initial baseline.
Evidence: preserved precheck receipt in .task/feature-agent-quality-phase05.md; R0=d9786f0f4128bbee43e27bdcc1534e320aae1711.
Impact: task metadata only; the feature workspace starts at d9786f0f41.
Refs: .task/feature-agent-quality-phase05.md
Why: branches merged into main had left their task cards open; backfill status and archive to prevent bookkeeping debt.
Evidence: feature-agent-quality-phase04.md(PR#290) — merges verified via git log --merges against origin/main.
Impact: .task/*.md moved to .task/archive/ with status backfilled; no code or submodule change.
Refs: task.sh close (card-autoclose-r1)
Why: The Dev combination must test the working-method prompt set and the
compose demotion.
Evidence: SELF - gitlink equals backend feature/agent-quality-phase04 head.

Why: branches merged into main had left their task cards open; backfill status and archive to prevent bookkeeping debt.
Evidence: feature-agent-quality-phase03.md(PR#288) — merges verified via git log --merges against origin/main.
Impact: .task/*.md moved to .task/archive/ with status backfilled; no code or submodule change.
Refs: task.sh close (card-autoclose-r1)
Why: The Dev combination must test the workspace-tool opening and the build
pipeline.
Evidence: SELF - gitlink equals backend feature/agent-quality-phase03 head.
Impact: Pointer only.
Why: establish the authorized task workspace and its initial baseline.

Why: include the current integration baseline before verification.
Evidence: fetched origin/main=7d52861f15f2b25dd5121301ac1e92b5a5e16f8d.
Impact: integrate upstream changes without rewriting task history.

Why: Backend #114 (EXT-14, commands-as-tools) added the runmgr -> cmdbus
production import but its Dev-side ratchet update went missing, so make test
fails on any Dev head combining it (backend CI does not run the Dev
architecture check). Recorded here with the merge that surfaces it.
Evidence: SELF - lint-boundaries passes after the entry; the edge exists in
backend main (internal/runmgr/runmgr.go imports cmdbus).
Impact: Ratchet baseline only; unblocks the Dev combination for all in-flight
work.
Why: git receive-pack runs 'gc --auto' in the background after a push;
the fixture's TemporaryDirectory teardown then races the gc writer and
fails with OSError 39 (remote.git not empty) — observed on the PR #285
runner (job 1967). The fixture remote holds no durable value, so auto-gc
is pure flake surface.
Evidence: the failing test passes 5/5 locally after the fix; full
make test-governance green (104 tests).
Impact: test fixture only; no governance-script behavior change.
Refs: Dev CI run 1438 job 1967; same race family as the upload-host
TempDir flake fixed earlier.
Why: Backend #115 (transcript-authoritative switch) and #118 (squad pin
alignment) merged; the Dev combination tests the merged head.
Evidence: SELF - gitlink equals backend origin/main head; make test recorded
on the task card after this commit.
Impact: Pointer only.
Why: the EXT-16 acceptance is escape-negative driven; the tool-written
evidence row captures the local bwrap run (all probes blocked, product
task visible) and the card summary states scope and follow-ups.
Evidence: go test -run 'TestSetExecBackendValidation|TestSandboxArgvShape|
TestSandbox|TestDirect' via CMD=... make evidence exit 0 (10 tests,
bwrap 0.11.1); make test row recorded earlier at this head.
Impact: task card only.
Refs: proposal 2026-10-09-ext-g1-b1-b3 (EXT-16); Backend #119.
Why: EXT-16 abstracts the interpreter launch point into an ExecBackend
port (direct = byte-identical status quo; sandbox = bwrap isolation:
ro root, tmpfs /home+/tmp, session/skills-only writable mounts, no
network, ulimit -u fork cap, timeout kills the namespace) with config
key execBackend, env AGENT_SYSTEM_EXEC_BACKEND, CLI --exec-backend and
extension.Options.ExecBackend (SurfaceVersion 2.6.0-experimental).
DisableExecTools stays the top-priority fail-closed switch; RDM keeps
DisableExecTools=true until G3-7.
Evidence: Backend #119 head 4badecb vet-and-test CI success, merged as
1a55089; local escape negatives all blocked (home secret, sibling
session, network, 400-proc spawn storm, 60s-sleep timeout kill,
orphan die-with-namespace) recorded in the task card evidence rows;
full make test at this head recorded on the card.
Impact: umbrella gitlink only; no source edits outside modules/backend.
Refs: proposal modules/documents docs/proposals/2026-10-09-ext-g1-b1-b3
(EXT-16); Backend #119; Backend #110 (DisableExecTools).
