Protocol: tmg-grill-round — both agents seeded with --new and executed SESSION-BOOTSTRAP.md Steps 1–8 before the round; questions capped at 10; sequential verbatim relays.
Topic: grill both the diagnosis and the plan of round 005 (stdin piping + TTY-aware output contract), verified against the code, the truth tree, and the tell-me-go reference.
Round 005 turns tellme from a "prompt must be an argv string" CLI into a pipeline-composable one: it can read the prompt from standard input and its output contract is TTY-aware, matching tell-me-go's posture. The user-visible delta is cat file | tellme "summarize" working, plus a pinned guarantee that a redirected answer is the answer text alone. The round is delivered end-to-end through the AIxBDD pipeline (21/21 tasks [X], specs/plans/005-stdin-piping/tasks.md), and it lands in three places: product code (internal/cli/prompt.go is new; internal/cli/cli.go is changed to a run(args, version, stdin, stdout, stderr, isTTY) seam with Run binding the real os.*), interface truth (specs/truth/features/cli/chat/piping-a-prompt.feature, piping-the-answer-out.feature, +9 rows in chat/dsl.md), and the ledger (truth-delta.md: /axb-technical-research MODIFY ×4, /axb-dsl-refine ADD ×2 + MODIFY ×1, /axb-api-plan and /axb-data-plan NOOP). It satisfies acceptance-coverage (both plan-side acceptance features are carried by interface features), dsl-exact-one-match (topology audit PASSED, 261 steps), and delta-covers-all-owners.
Four decisions, all verified against the reference source, not just its docs. Scope (Clarify Q1): piping only; -r is deferred because tellme emits no rendered output, so its bytes already equal tell-me-go's -r output — a literal -r would be a dead flag (FR-011, techstack.md "Not Introduced Yet"). The combine rule (Q2): the prompt is strings.Join(args, " ") + "\n" + piped bytes, then TrimSpace — I confirmed this is byte-for-byte the reference's main path (tell-me-go/internal/ui/capture.go: combined = prompt + "\n" + string(bytes) then finalizePrompt → TrimSpace), not its callback-worker "arg wins" path. The TTY-aware contract (Q3): presentation suppressed when stdout is not a terminal, mirroring session_manager.go:260 (UseColor: isTTY && !sc.GetRawOutput()). The 1 MiB cap: maxStdinBytes = 1 << 20 in prompt.go matches the reference's maxPromptSize = 1024*1024, and resolvePrompt reads stdin only when it is not a terminal (isTTY(stdin) gating), which is what keeps interactive use from hanging (FR-004/FR-008). The diagnosis is sound: the reference reads the pipe regardless of whether an argument is present, and combinePrompt does the same.
The change stays inside the existing CLI package — no new package, no new dependency (go.mod unchanged). The seam inverts OS coupling exactly the way round 003 inverted os.LookupEnv: cli.Run supplies os.Stdin/Stdout/Stderr and defaultIsTerminal; run and resolvePrompt receive them injected so the prompt-combination and I/O-mode matrix are pure and unit-testable (research.md Decision 4, folding issue #14). prompt.go holds four small pure seams — combinePrompt, readPipedStdin (io.ReadAll(io.LimitReader(r, maxStdinBytes))), defaultIsTerminal (stdlib *os.File + os.ModeCharDevice), and resolvePrompt — with dispatch precedence --version → -d → prompt turn → boot so --version/-d never read stdin (FR-010). Tests are two-layer: internal/cli/prompt_test.go (table-driven: combine matrix, TTY×arg×stdin mode selection, read-error propagation, bounded read, parseFlags) plus black-box E2E — harness.RunWithStdin feeds a pipe (a non-char-device, so the child reads it) and 9 self-registering per-file stepdefs (step_t006–step_t014, Zero Shared Edits via register.go). The output contract is realized as renderTurn's fmt.Fprintln(out, resp.Text) (answer on stdout only, one trailing newline) with no global-stream writes after the F3 fix.
I would defend the diagnosis and the mechanical delivery, but I would volunteer four soft spots rather than have them extracted. First, the "stdin is read only on the prompt-turn path" claim is imprecise. run calls resolvePrompt on every non---version/non--d dispatch, so a piped-but-empty, no-argument run does read stdin (bounded, gets empty) and then falls through to boot — the offline guarantee (NFR-004, zero network) still holds, but both techstack.md's "Prompt input" row and the PR body over-state the read scope by excluding the boot fall-through. The accurate phrasing is "read only on the non-version, non-diagnostic path." Second, the F2 reconciliation was partial. F2 fell for a phantom isTTY(stdout); the fix reconciled techstack.md and research.md, but plan.md:38 still says "gates presentation on isTTY(stdout)" and tasks.md T019's boundary still says "以 isTTY(stdout) 閘控任何呈現" — the plan package still carries the over-claim the truth no longer does. Third, the TTY output contract is a pin with a zero behavioral delta today — no isTTY(stdout) is ever computed (I grepped: it appears only in docs), so FR-007 and the "no terminal decoration" step can never fail; they are forward-looking, and the round's real, falsifiable deliverable is the stdin ingestion. Fourth, two design choices are judgment calls I'd want stress-tested: the char-device proxy reports "terminal" for /dev/null (the research records this honestly, and it is what preserves round-004's offline boot behavior for the existing E2E scenarios, since harness.Run leaves cmd.Stdin unset → the child reads /dev/null), and the 1 MiB cap truncates silently rather than erroring — defensible as reference-parity but it means an oversized pipe is silently narrowed. I would also note the "completes without waiting" step is a weak assertion (runErr == nil && stdinSet) that relies on the suite's own hang-to-timeout as the real signal, and that the "pipes nothing" interface Example drops the acceptance-level "configuration: ready" assertion in favor of the no-network + success pair. None of these block merge; all are refinements I'd rather own explicitly than defend as "fine."
Q1 (griller): You filed the plan.md:38 / tasks.md:202 divergence under "the F2 reconciliation was partial… the plan package still carries the over-claim the truth no longer does" — and closed it as "None of these block merge." But I read that line differently: tasks.md is the execution control plane, and the Phase 4B Boundary (which governs T019/T020, both marked [X]) still instructs the implementer to "以 isTTY(stdout) 閘控任何呈現 … 只 pin 契約." The shipped code computes no stdout probe, and post‑F2 the truth now says the stdout probe is deferred. So we have a task marked complete whose stated Boundary was not executed, in a ledger that was not corrected, with a truth‑delta that records the techstack reword but is silent on the plan-side contradiction. Which of these is the truth of the round? … My recommendation: Option 1, with a narrow fix — amend the Phase 4B Boundary text (and the plan.md:38 comment) … and record that withdrawal on the F2 truth-delta row … I do not accept "non-blocking": a [X] task whose Boundary contradicts both the code and the reconciled truth is a ledger-integrity defect, not a wording nit.
A1 (subject): I accept Option 1 — fix before merge. I retract my "non-blocking … wording nit" characterization; you are right that it is a control-plane/ledger-integrity defect, and I accept the pre-merge window argument. … First, Option 2 is not a defensible position on the facts — plan-package-frozen binds a package at delivery, not while it is active; round 005 is un-merged, and the round's own F2 fix (acc4c82) already amended plan-package artifacts (research.md, truth-delta.md) in this exact window. So the divergence is inconsistency the round's own fix introduced: F2 rewrote the narrative while leaving the control plane (tasks.md Phase 4B Boundary) and the source-structure comment (plan.md:38) asserting the withdrawn probe. Second, the fix locus in your recommendation is slightly off — truth-delta.md is a ledger of TruthArtifact changes; plan.md/tasks.md are plan-side, so "record the withdrawal on the F2 truth-delta row" cannot be the primary fix. Concretely: (1) reword the tasks.md Phase 4B Boundary; (2) plan.md:38 likewise; (3) a one-line cross-reference on the F2 truth-delta row. On method, I side with your audit-trail-preserving variant — annotate the deviation (superseded by F2 — stdout probe deferred; seam wired to stdin this round) rather than blank-replacing the original clause, and keep T019/T020 [X] — their Test Scope was met; what was unmet was the Boundary's mechanism clause, not the verified behavior.
Q2 (griller): specs/truth/techstack.md:19 states verbatim: "…standard input is read only on the prompt-turn path." The code contradicts that: printf '' | tellme → run reaches resolvePrompt before the turn-vs-boot branch; isTTY(stdin) is false (a pipe), so readPipedStdin reads it, combinePrompt returns "", and the run falls to renderBoot. So stdin was read on a run that is not a prompt turn. The same false phrasing recurs in research.md Decision 6, tasks.md, plan.md, and the run docstring. Which resolution: 1. It's a truth-accuracy defect; fix the truth (behavior stands). 2. The behavior is wrong; fix the code. 3. Something else. My recommendation: Option 1 … the fix belongs in specs/truth/techstack.md itself (owner /axb-technical-research), with the truth-delta row #1 updated to match.
A2 (subject): I accept Option 1, and I accept the characterization as a truth defect (owner /axb-technical-research) a fortiori. I retract my "imprecise wording" filing a second time. The reason Option 3 fails is internal to the row: it names boot as a distinct dispatch outcome from prompt turn one clause earlier, so "prompt-turn path" cannot be shorthand for "the turn and the boot fall-through." Option 2 is rejected on the mechanism: at the io.Reader seam you cannot know the pipe was empty without reading it, so "boot never reads stdin" is not an implementable predicate without an fd-level peek; NFR-004 constrains network, not reads; the reference reads the pipe before deciding. So the fix is: reword the truth to the exact predicate — standard input is read on the non-explicit-mode dispatch path (the prompt-resolution step shared by the reasoning turn and the empty→boot fall-through); --version and -d never read it. Per truth-single-owner, only /axb-technical-research may write techstack.md. On the ledger: not duplicate authority — either correct row #1's summary, or add a single review-driven row mirroring the #4 pattern — exactly one of the two. Same mandate as Q1: fix before merge.
Q3 (griller): techstack.md "Not Introduced Yet" records the renderer as not introduced — and Q1 deferred -r on the ground that "a literal -r would be a no-op flag." Yet the same round records the renderer's suppression half as enforced truth (interface Rule piping-the-answer-out.feature Rule 1; the DSL row "carries no terminal decoration"; FR-007; NFR-003). No code computes isTTY(stdout) and nothing emits an escape sequence, so the Then cannot fail. The round applied "no-op ⇒ defer" to the flag but "no-op ⇒ pin" to the contract. Is that coherent? My recommendation: Option 2 — a classification fix, not a deletion (keep the Then for coverage; record the suppression half as a forward-pin).
A3 (subject): I stand by Option 1 — accepting only a cosmetic provenance marker, rejecting your defect diagnosis. The concession: an explicit pending the renderer marker is harmless cosmetics. Rejection: this is not the Q1/Q2 defect class — the predicate is true, not false: renderTurn does fmt.Fprintln(out, resp.Text), so the captured stdout genuinely contains no ANSI today. "You correct false predicates; you do not defer true ones." Four grounds why "no-op flag ⇒ defer" does not compel "no-op contract ⇒ defer": (1) surface vs. guard; (2) self-arming — the guard becomes a live regression detector the instant presentation exists; (3) antecedent — FR-007 is a condition whose antecedent is currently false, hence vacuously satisfied; (4) coverage. And the deferral is already recorded in four places (spec.md Assumptions, the Terminal-detection row, "Not Introduced Yet", the feature comment). So: Option 1 substantively; Option 2's remedy only as optional cosmetics; Option 2's diagnosis rejected.
Q4 (griller): I concede Q3's core (the predicate is true of the bytes; FR-007 is vacuously satisfied; the deferral is disclosed). But the defense's load-bearing pillars (points 2 and 4) rest on the no-decoration row doing detection work its sibling assertion already does. (1) piping-the-answer-out.feature Rule 1 carries both is exactly "{answer}" and carries no terminal decoration; if a future renderer leaked ESC, is exactly would already fail. (2) The row's own clauses disagree in scope: 必查 = "contains no ANSI escape sequences" (content-blind, absolute); 不該發生 = "not wrapped in presentation control codes" (system-added only); FR-007 is the latter. Counterexample: an answer that itself contains ANSI (resp.Text = "red \x1b[31mtext") → stdout = red \x1b[31mtext\n is correct behavior; is exactly passes, but the row's 必查 would fail it. My recommendation: Option 1 — narrow the 必查 to no system-introduced presentation codes.
A4 (subject): I accept Option 1 — and yes, I concede the row's 必查 and 不該發生 describe two different predicates, and that my point-2 pillar does not survive in its strong form. I over-stated in Q3. step_t013 is if strings.Contains(sc.stdout, "\x1b[") — content-blind; with resp.Text = "red \x1b[31mtext" on a pipe, step_t012 passes, step_t013 fails. FR-007 suppresses system-added presentation; NFR-003 says output must not depend on terminal detection beyond the suppression rule — so passing the answer's own bytes verbatim (ANSI included) is correct, and the row would reject it. Point-2 retreats because the detection value is not the row's — any decoration tellme adds changes the byte stream, so is exactly already fails on every real leak. So the fix is Option 1: narrow 必查 to FR-007's actual contract, keep the step, correct the ledger — locus is specs/truth/features/cli/chat/dsl.md, owner /axb-dsl-refine (a different owner than Q1/Q2), recorded as a corrective MODIFY. One honest consequence: narrowed to be correct, this row's assertion collapses onto is exactly; its value becomes an explicit carrier of FR-007's intent — documentation with a test attached — not an independent detector. Severity: latent (no canned answer carries ANSI today) but a genuine contract error. I stand corrected on Q3's claim.
Q5 (griller): renderTurn ends with fmt.Fprintln(out, resp.Text) — it unconditionally appends one \n. parseAnswer returns the content untrimmed. So for an answer "hi\n", stdout = "hi\n\n". Compare: FR-006 ("exactly one trailing newline"); the DSL row 必查 ("equals {answer} followed by exactly one trailing newline"); the Rule title ("the answer text alone"). These do not name one predicate. The suite cannot tell the difference — every fake answer is newline-free. My recommendation: Option 1 — keep the code, fix FR-006's wording, add the falsifying scenario.
A5 (subject): I accept Option 1 — keep the code, fix FR-006's wording, add the falsifying input class. And I reject Option 2: it mutates content to satisfy a byte count. The precision: the executable truth already implements Option 1 — step_t012 computes want := answer + "\n", so code and DSL agree; the artifact that reads as Option 2 is the wording (FR-006's "exactly one trailing newline"; the row's 必查), where the word trailing invites the false reading. That makes Q5 a wording defect, not a behavior defect. Ownership: FR-006 is a Spec (PM-owned, spec-pm-authored); the DSL row prose is /axb-dsl-refine. One correction: "add a scenario with a newline-terminated answer" is not a one-line addition — the current DSL cannot express that input (step_t010 passes {answer} verbatim; Gherkin params are single-line), so it is unrepresentable, not merely absent. The newline-terminated class needs a new mechanism (a new Given row + stepdef, or an escape convention). Severity: the sharpest contract-definition issue — it names the round's core output predicate and the falsifying class is unrepresentable — but same shape as Q3/Q4. Fix before merge, keeping renderTurn as it is.
Q6 (griller): step_t010 passes {answer} verbatim through the single-line matcher; fakeprovider.jsonString would round-trip a "\n"; harness.Run leaves cmd.Stdin nil (→ /dev/null, read as a terminal), RunWithStdin uses strings.NewReader (→ an os.Pipe), and stdout is always a pipe — never a real TTY; step_t014 has no time bound. So the four flagged assertions share one structural cause. My recommendation: Option 1 — fix the representable input surface (newline/ANSI-answer class; bounded-time "did not block") and explicitly record the pty/TTY branch as unverifiable-this-round.
A6 (subject): I accept Option 1 — but it must be root-cause + rows, not root-cause instead of rows, and "permanently unverifiable" must become "unverifiable this round." The synthesis is right and it's the strongest thing in the grill. But the cause is an enabler, not a substitute — Q4's defect is a false predicate the surface did not create; Q5's is a wording mismatch. And the interlock settles it: the moment you add an ANSI-bearing-answer class, step_t013 goes red on a correct run — so the Q4 predicate fix is a precondition for widening the surface. Representable fixes: (a) a DSL way to express a newline/multi-line answer; (b) a bounded-time run (exec.CommandContext + ceiling — a falsification bound, not a time.Sleep synchronization, so ADR-036 holds); (c) the Q4/Q5/FR-006 fixes that (a) forces. No dependency; converts Q5 and spot-5 from vacuous to live while forcing Q4's correction. On the word: nothing is permanently unverifiable; the honest classification is unverifiable-this-round (real-TTY fidelity + the stdout-is-a-terminal suppression branch need a pty + the deferred renderer). Where it lands is cross-owner: test infra (tests/e2e/harness/**), /axb-dsl-refine (new Given + Q4/Q5), /axb-technical-research (Testing row), PM (spec.md Assumptions / "Not Introduced Yet").
Q7 (griller): specs/truth/features/cli/dsl.md:40 enumerates the environment phrase's causes ("one class for the not-usable and unset paths"); exitcode.go documents EnvironmentError = 4 // runtime home unset/unusable, workspace unusable. Round 005 emits the same phrase for a third cause — a stdin read failure, where the home is intact — so the phrase text is false for that cause, and exit code 4's documented meaning doesn't cover it either. STATUS.md records F1 as "no truth change" — but F1 changed which phrase that path emits, and the phrase's meaning is enumerated in truth. My recommendation: Option 1 — record the overload + retract "no truth change".
A7 (subject): I accept Option 1 — retract "no truth change" is a precondition, not a garnish — and I reject Options 2 and 3, each on a structural ground. F1 is a truth change: the phrase's cause-mapping is enumerated in the interface-root dsl.md and the exit-code semantics are truth-published. Option 2 is wrong because "stdin unreadable" is not a peer class — it is an environment condition, so it belongs under the environment phrase; a tenth phrase would mis-model the class structure. Option 3 is not a clean third way: its "surface it without the home phrase" variant has no cataloged home-free phrase (degenerates into Option 2 or an uncataloged line — the F1 defect reintroduced); its "fall through to boot" variant silently discards a bound I/O failure, converting a loud correct failure into a silent no-op — a worse violation. On the exit code: keep 4; the value is right, its meaning is incomplete (a documentation-of-meaning widening). And I'd name the permanent smell: the phrase's text is home-texted while its class is environment-wide — predating F1; Option 1 is the proportionate fix this round, but the honest long-term fix is a class-level phrase, which changes an existing frozen phrase → a freeze-breaking change out of scope → a forward ADR-worthy note.
Q8 (griller): FR-007 permits color/spinner/rendering at a terminal; NFR-003 requires stdout bytes identical across repeated runs. Clause 1 forbids run-to-run variation; clause 2 explicitly permits terminal-dependent output via FR-007 — and FR-007 names a spinner. A time-driven spinner differs run-to-run at a terminal → clause 1 false, clause 2 permits it. NFR-003 cannot be satisfied for the terminal case. My recommendation: Option 1 — scope NFR-003 to the redirected/non-terminal stream; optionally drop "spinner".
A8 (subject): I accept Option 1's scoping — and I reject both Option 2 and the "already scoped" reading. But I'd decline the de-pin. The "no change needed" reading fails on grammar: clause 2 carves out terminal-dependence, not run-identity; a time-driven spinner produces the latter, so clause 1 is violated and clause 2 does not reach it. Option 2 is wrong because it deletes the guarantee that matters — byte-identity across runs is a pipeline guarantee, coterminous with the redirected stream the round actually tests. Scoping NFR-003 to the non-terminal stream makes FR-007 and NFR-003 cover disjoint streams. And I decline the de-pin — "spinner" is the witness of the contradiction, not its cause: the conflict is FR-007's general terminal permission; removing "spinner" would hide the witness while leaving the contradiction live. Classification: a fourth flavor — a requirements contradiction within one authoritative artifact; latent but pinned. Locus: spec.md (spec-pm-authored) — a PM-side correction.
Q9 (griller): The grill has accumulated an owner-mapped correction set (Q1–Q8). Two items are different in kind: the class-level phrase rename (freeze-breaking) and the pty harness (a new dependency). What is the cut line — and does "FULL APPROVAL — READY TO MERGE" stand? My recommendation: Option 1 — in-flight = corrections to artifacts round 005 authored/pinned/invalidated; deferred = needs a new capability/dependency or rewrites a pre-005 frozen artifact; and since merge ⇒ freeze, "READY TO MERGE" no longer holds until the in-flight set lands.
A9 (subject): I accept Option 1 — but I'd sharpen two words. Sharpen #1: "don't rewrite frozen history" is nearly a dead letter — merge freezes the plan package, not specs/truth/** (truth is truth-current, live). The real deferral grounds are: (i) needs a new capability/dependency → the pty harness; (ii) changes pre-005 operator-visible behavior/contract text → the class-level phrase rename. Sharpen #2: apply the criterion per-change, not per-finding — Q7 splits into record the third cause (in-flight) vs class-level rename (deferred); Q6 splits into representable half (in-flight) vs pty harness (deferred). In-flight set: Q1, Q2, Q4, Q5, Q6(representable), Q7(record-the-cause), Q8, across four owners (PM, /axb-technical-research, /axb-dsl-refine, + test code/plan-side prose). Why not Option 2: the rename changes pre-005 behavior → its own ADR/round. Why not Option 3: "changes no observable behavior today" is exactly the excuse that lets false artifacts get frozen (the F1 "no truth change" error); and Q4 is not independently deferrable — Q6's surface widening forces it. On the merge question: "FULL APPROVAL — READY TO MERGE" is superseded for the changed artifacts (merge ⇒ freeze ⇒ permanent plan-side falsehoods + orphaned truth corrections), while the code-level approval stands (the pass is docs + test code only; no internal/ behavior change). Downgrade to "changes requested: one in-flight correction pass across the four owners, then a single re-review" — the F1–F3 precedent, scoped to docs and tests.
The Subject's diagnosis held up: scoping to piping-only and deferring -r, the args + "\n" + stdin combine rule (verified byte-for-byte against the reference's main path, distinct from its callback-worker "arg wins" path), the TTY-aware posture, and the isTTY(stdin)-gated 1 MiB bounded read all check out — the mechanical delivery is sound and the product behavior is correct. Where it did not hold up is the artifact layer: the grill extracted five distinct defect flavors — a false predicate in truth (Q2), a false predicate in the plan-side control plane (Q1), a wrong predicate in the decoration 必查 that would misfire on a correct run (Q4), a mis-recorded truth change ("no truth change" for F1, Q7), and a requirements contradiction inside spec.md (FR-007's spinner vs NFR-003, Q8) — plus a structural root cause (the harness/DSL input surface, Q6) and a mis-named core output predicate (FR-006, Q5).
Recommendation: proceed with changes — land one in-flight, four-owner pre-merge correction pass (docs + test code only — no internal/ behavior change), then a single scoped re-review; the prior "FULL APPROVAL — READY TO MERGE" is superseded for the changed artifacts while the code-level approval stands, and the class-level phrase rename and the pty harness are named and deferred, not built.

- Class-level phrase rename (
the runtime home is not usable→ environment-class text) — changes pre-005 contract text and ripples into round-001/002 features; its own ADR-round. - pty-capable harness (real-TTY stdin fidelity + the FR-007 stdout-is-a-terminal suppression branch) — needs a dependency round 005 forswore; a future dependency-authorized round.
- 1 MiB silent truncation (spot 4): verified reference-parity (
captureFromPipetruncates silently) and spec-compliant (NFR-001 bounds; no error required). Defensible; no change. /dev/null-as-terminal proxy (spot 4a): no observable defect; its fidelity limit folds into Q6's "unverifiable-this-round" naming.
I accept the verdict. The diagnosis held; the code is right; the artifact layer is where the round is not yet true — and because merge delivers the package, the fix belongs in the pre-merge window. I accept proceed with changes, the four-owner in-flight pass (docs + test code only), the single scoped re-review, and the supersession of "FULL APPROVAL — READY TO MERGE" for the changed artifacts while the code-level approval stands.
What I stand by (unchanged). The scope decision; the combine rule (verified byte-for-byte against capture.go's main path); the TTY-aware posture and the isTTY(stdin)-gated, 1 MiB-bounded read; the injected run(...) seam. That Q2's read-scope and Q1's boundary text are wording errors, not behavior errors, is the load-bearing point of my defense — and it survived (no file under internal/ changes behavior; Q7's exitcode.go edit is a comment). I also stand by the two soft spots the grill let stand: the 1 MiB silent truncation (reference-parity, spec-compliant) and the /dev/null-as-terminal proxy (no observable defect).
What I revised. (1) Q1 — filed as plan-side "non-blocking wording"; it is control-plane integrity and pre-merge. (2) Q2 — filed as "imprecise" prose; it is a truth-accuracy defect in the authoritative Techstack, owner /axb-technical-research. (3) Q3 → Q4 — I retract that the decoration row's two clauses were both accurate; the 必查 is content-blind and would misfire on a correct ANSI-bearing answer; is exactly already arms against every real leak, so the row adds zero unique true positives and one false-positive class. (4) Q5 — refined: the step already implements Option 1, so the fix is wording (PM + /axb-dsl-refine), and the falsifying class is unrepresentable in the current DSL, not merely absent. (5) Q6 — corrected "permanently unverifiable" to unverifiable-this-round, and reframed the root cause as a precondition for the row fixes. (6) Q7 — retracted F1's "no truth change"; "stdin unreadable" is not a peer class but an environment condition; exit 4 is the right code, only its documented meaning widens. (7) Q9 — sharpened: truth never freezes; only plan packages do, so the deferral grounds are "needs a new capability/dependency" and "changes pre-005 contract text." The meta-lesson: I defaulted, repeatedly, to "the behavior is correct, therefore the artifact claim is minor" — when in this methodology the artifacts are the deliverable, so an untrue artifact is a first-class defect regardless of whether the behavior is right.
Open questions to settle in the correction pass. (a) Q6 mechanism: an escape convention vs a new Given row — and whether the falsifying newline/ANSI scenarios belong at the acceptance layer too. (b) Q4 end-state: keep a narrowed but redundant Then as FR-007's named carrier, or fold the clause into is exactly's prose (I lean to keeping the carrier). (c) Q7 ratification: knowingly leave a home-texted phrase as the environment class label, or prioritize the rename. (d) Q6/pty naming locus: techstack.md "Not Introduced Yet", a spec.md Assumption, or an ADR — I lean to recording it in both the truth and the spec. (e) Re-review scope: the re-check must test the interaction of the four owners' edits (Q6's input widening coupling to Q4's predicate fix; the Q2/Q7 truth edits not re-introducing an over-claim), not each finding in isolation.
Net, from my side: I hold the diagnosis and the code, I accept the eight-item correction inventory as scoped, and I treat the deferred pair — the class-level phrase rename and the pty harness — as named obligations for their own rounds, not as loose ends.
Round run as a tmg-grill-round between architect (subject) and griller, orchestrated by butler. Both agents were seeded with --new and executed SESSION-BOOTSTRAP.md Steps 1–8 before the round. 9 questions (cap 10), verdict + post-grill position recorded above.
