oimiragieo tensor-grep: design authorization ladder
Closes the gap between demand proven and product code licensed. Industry parallel (Exa /
Nygard 2011 ADR): significant choices land as short records with Context / Decision /
Alternatives / Consequences before implementation. We do not use the GitHub adr workflow
or doc/arch numbering — we use in-repo docs/requirements/ + docs/design/ +
docs/decisions/ packets with a shared revision id and content-hash (A46/A51). Proven on
DD-006 (2026-08-14/15). Full worked example:
references/dd006-ladder-worked-example.md.
When to use / NOT
| Your task | Use |
|---|---|
| Demand trigger SATISFIED; next work is a design/requirements/decisions packet | this skill |
| Operator says “skip Fable” / Fable quota-blocked on a named docs packet | this skill (A117) |
| Board row has mixed dispositions (demand ok / design landed / build not started) | this skill (A122) |
| PERF vs HONESTY (or similar) sub-dispositions must stay separate for full close | this skill |
| Sol/Codex exact-commit audit of packet bytes before merge | this skill |
| Measuring whether a DEMAND_GATED Trigger is satisfied | tensor-grep-demand-gate-measurement |
Implementing src/ after a deliberate build go |
tensor-grep-backlog-campaign + tensor-grep-change-control |
| Adversarial security gate on daemon/acceptor/auth code | A3 via change-control / enterprise-agent |
DO NOT USE FOR:
- Treating a merged design PR as SHIPPED or READY for CUJ close.
- Treating a Fable waiver as license to touch
src/, spend, or CEO_GATED flips. - Building Option A (
request_queue_size) without the R7 aggregate pre-auth cap (A121).
The ladder (numbered stages)
- Demand measure — bounded, plan-frozen probe; Trigger re-derived from
origin/main. Skill:tensor-grep-demand-gate-measurement. Outcome: SATISFIED / unmet / CANNOT_MEASURE. - Design packet — same revision id across
docs/requirements/,docs/design/,docs/decisions/. ADR-shaped sections (Context, Decision, Alternatives, Consequences) without claiming GitHub ADR tooling. Cite production symbols by name (e.g.request_queue_size,ThreadingMixIn,_DAEMON_CONNECT_TIMEOUT_SECONDS), never stale lines. - Sol exact-commit audit — hash designated packet bytes (
git hash-object); seat stamps the exact SHA/revision. APPROVE / REVISE / BLOCKER. No product code yet. - Optional Fable waiver (A117) — operator may waive the Fable design-audit seat for the named docs packet only after Sol APPROVE. Record on the PR. Does not clear product build, spend, or CEO_GATED (extends A74).
- Deliberate build go — explicit authorization before any
src// product-test / workflow change. Split sub-dispositions if full close needs more than one shippable slice (e.g. DD-006-PERF vs DD-006-HONESTY). - TDD + A3 — failing tests first; security-class surfaces (daemon acceptor, pre-auth paths, concurrency caps) get the mandatory adversarial gate before merge.
Fable waiver vs build license (A117)
| Cleared by “skip Fable” | Not cleared |
|---|---|
| Named docs/design/decisions packet after Sol exact-commit APPROVE | Product/src/ changes |
| Merging that docs PR | Spend or CEO_GATED flips |
| Recording the waiver on the PR | Treating a quota substitute as durable clearance (A74) |
A117: waiver is seat-scoped and artifact-named. Build still needs stage 5 + 6.
Design ≠ SHIPPED (A122)
Demand SATISFIED + design packet on main is not SHIPPED. Keep the parent row open with
honest mixed dispositions (e.g. demand done / design landed / PERF+HONESTY product not started).
Do not flatten to READY or close on docs alone. Full parent close needs every linked
sub-disposition’s product code under a deliberate go.
Measurement envelope (A120) + backlog+R7 (A121)
A120 — three time numbers. Freeze probe duration, frozen grace, and enclosing shell timeout. Outer timeout must strictly exceed duration + grace. Equal timeouts are Sol REVISE (the probe cannot finish cleanly).
A121 — backlog without R7 is incomplete. Raising request_queue_size (listen backlog) without
a finite fail-closed aggregate pre-auth concurrency cap enlarges DoS admission.
ThreadingMixIn spawns a thread per accept; a larger backlog alone is Sol BLOCKER-class for
DD-006-PERF. Pair backlog change with R7 (or equivalent named cap) in the design before build.
Client connect budget lives in _DAEMON_CONNECT_TIMEOUT_SECONDS — cite by name when discussing
warm→cold fallback honesty.
Sol exact-commit audit
- Shared revision id on requirements + design + decisions.
git hash-object(or designated worktree bytes) — record method + digest (A46).- Seat reads that exact artifact; verdict binds that SHA only (A51). Newer worktree bytes lose clearance.
- Fold BLOCKER/REVISE into the packet before merge; do not “fix in the build.”

through design packet #1015, Sol, Fable waiver, and the still-open PERF+HONESTY build gate.
