tie-safe AUC-PR and sound kill criteria The pre-edit hook passed the predictor only the file path, so four of its seven features were pinned to 0 and risk topped out at sigmoid(-1.0) = 0.27, below the 0.66 "high" band: the advisory could never fire. The hook's risk block now computes caller fan-out and test coverage from one bounded git grep of the module name, whether the edit rewrites an existing declaration, and whether any caller is in the working diff, and names the reasons. A hot file with ten importers, no test and a rewritten signature scores 0.91. predictor.js: aucPr ranks tied scores as one threshold (the same data gave 1.0 or 0.333 depending on input order). The kill criteria no longer decide on a held-out split under 10 samples / 2 per class, and compare AUC-PR with the exact expected AP of a random ranking instead of a fixed 0.6 floor.

A Formal Theory of the Cognitive Substrate for Coding Agents

Abstract

-

A large language model used for coding is a fixed probabilistic map, y = fθ(x): stateless, frozen, and bounded in context. Three research efforts converged, independently, on the same conclusion — that the remedy is not a better prompt or a bigger model but an external, stateful architecture wrapped around the frozen core. This paper proves they are describing one object. We show that the substrate's impact-awareness faculty and the framework's change-closure fixpoint Δ* are the same mathematics; that the assumption gate and the amnesia equation assumption ≈ argmax P(convention | training) are the same phenomenon; and that both reduce to a single two-layer duality: a probabilistic instruction layer that raises the probability p<1 of correct behaviour, and a deterministic interception layer that guarantees a floor. The central theorem states that neither layer alone can make an agent reliable — a direct formalization of the discipline never trust the output of a probabilistic engine; earn trust with an external check. We give definitions, the duality theorem with proof, a unified seven-algorithm task loop, the probabilistic failure model P(≥1 miss)=1−pn, and carry through the six correctness theorems of the reliability framework. Two prototypes — an impact oracle and a complexity-router/assumption-gate — instantiate the deterministic layer and are evaluated honestly. The forgekit / claude-e2e-kit codebase is the deployed binding. The Qur'anic lens supplies the vocabulary of epistemic obligation (tabayyun, amāna, lā taqfu) that names why each safeguard is mandatory rather than optional.

A large language model used for coding is a fixed probabilistic map, y = fθ(x): stateless, frozen, and bounded in context. Three bodies of work, developed separately from different starting points, converged on the same conclusion — that the remedy is not a better prompt or a bigger model but an external, stateful architecture wrapped around the frozen core. This paper argues [corrected 2026-09-21] they are describing one object; their agreement is consistency rather than independent evidence, since forgekit was built as a binding of the other two [corrected 2026-09-21]. We show that the substrate's impact-awareness faculty and the framework's change-closure fixpoint Δ* have the same shape, the oracle approximating the fixpoint over a different relation [corrected 2026-09-21]; that the assumption gate and the amnesia equation assumption ≈ argmax P(convention | training) are the same phenomenon; and that both reduce to a single two-layer duality: a probabilistic instruction layer that raises the probability p<1 of correct behaviour, and a deterministic interception layer that multiplies down what escapes it. The central result, restated in the 2026-09-21 corrections as a bound on the residual over an explicit region of (instruction-following, catch) probabilities rather than as an impossibility theorem [corrected 2026-09-21], is a formalization of the discipline never trust the output of a probabilistic engine; earn trust with an external check. The composition law itself is standard layer-of-protection algebra, and two concurrent preprints derived a strictly more general Bayesian form of it first; we concede priority [corrected 2026-09-21]. We give definitions, the duality result, a unified seven-algorithm task loop, the probabilistic failure model P(≥1 miss)=1−pn (for independent tasks), and carry through the six correctness theorems of the reliability framework. Two prototypes — an impact oracle and a complexity-router/assumption-gate — instantiate the deterministic layer; both of their headline results were later refuted on data the authors did not build [corrected 2026-09-21]. The forgekit / claude-e2e-kit codebase is the deployed binding. The Qur'anic lens supplies the vocabulary of epistemic obligation (tabayyun, amāna, lā taqfu) that names why each safeguard is mandatory rather than optional.

    Two of these three “identities” are weaker than this callout says: the impact oracle approximates Δ* rather than computing it (§3.2), and the duality is a bound over a region of parameters, not a theorem for every p, c < 1 (§4). See the Corrections. [corrected 2026-09-21]

    The synthesis also inherits a governing discipline, stated plainly by the practitioner who commissioned this work: AI output is a mathematically calculated probability; it must never be trusted blindly; for the same prompt it can give a different answer, so use only the capability it is genuinely best at, and earn trust with an external check. We will see that this sentence is not a slogan but the informal statement of the central theorem — the quantity (1−p)>0 that forces a deterministic layer to exist.

The rest of this paper makes "cannot be relied upon" precise and shows what "enforce" must therefore mean.

    The substrate's Impact Oracle computes a file's blast radius by reverse reachability on the dependency graph, which has the same shape as the closure (4). It is not the same object. The oracle adds a real-valued confidence that decays with graph distance, keeps only what clears a threshold, stops at depth 10, and walks the AST import/call relation rather than the framework's R (which also carries documentation and declared edges). So it approximates Δ* over a different relation. Earlier versions said the two were the same computation and that this was why the prototype achieved perfect recall. That inference was wrong: completeness relative to a relation says nothing about whether the relation holds the edges that matter, and on nine real repositories the oracle's recall was 0.022 (§10).

    4 The central result — the two-layer duality theorem

    A substrate's behaviour-shaping is partitioned into two layers over the frozen model:

    • The probabilistic layer (Π3): standing instructions loaded into context — CLAUDE.md, rules, skills, protocol cards. Let p = P(the agent performs the required behaviour on a task — e.g. the full closure Δ* — under the instruction layer alone).
      • -
    • The deterministic layer (Π2): code executed at fixed lifecycle points independent of the model's choices — hooks that inject state, or that block a turn. A deterministic check j catches a target miss with probability cj, and for a decidable structural signal cj → 1.
      • +
    • The deterministic layer (Π2): code executed at fixed lifecycle points independent of the model's choices — hooks that inject state, or that block a turn. A deterministic check j fires with probability cj = P(check j fires | miss). A decidable check detects its proxy signal exactly, but cj is the probability that a miss shows that proxy. That depends on the agent's behaviour as well as on the check, so it is not a property of the gate alone (§5.2). [corrected 2026-09-21]
    -
    Theorem D (Two-layer duality — neither layer alone suffices)
    -

    Let a task require a behaviour whose omission is a silent miss. Under the instruction layer alone the per-task silent-miss probability is 1−p; under a deterministic layer of k checks the residual silent-miss probability is

    -
    (5)P(silent miss) = (1−p) · ∏j=1..k (1−cj).
    -

    Then, for any model whose instruction-following is imperfect (p<1) and any deterministic layer that is not omniscient (cj<1 for every j):

    +
    Theorem D (Two-layer duality, restated as a bound [corrected 2026-09-21])
    +

    Let a task require a behaviour whose omission is a silent miss. Let M be the event that the agent omits it under the instruction layer, so P(M) = 1−p, and let q = P(at least one of the k checks fires | M). The per-task residual is exactly

    +
    (5)r = P(silent miss) = (1−p) · (1−q) = (1−p) · P(no check fires | M).
    +

    With cj = P(check j fires | M), and no independence assumption, max(0, 1−Σjcj) ≤ 1−q ≤ 1−maxjcj (Fréchet bounds). The product (1−p)·∏j(1−cj), which earlier versions gave as Eq. (5), is the special case in which the checks fire independently given the miss. When the checks are nested, for example the same classifier run at several points on the same diff, r = (1−p)(1−cmax).

    +

    Then:

      -
    1. The probabilistic layer alone cannot reach reliability. With k=0, P(silent miss)=1−p>0, and over n tasks P(≥1 miss)=1−pn → 1. No amount of instruction-writing removes the residual, because instructions are context, not enforcement.
      2. -
    2. The deterministic layer alone cannot reach reliability either. A decidable check bounds only the structural signal it was built to detect; semantic correctness is undecidable (§12), so ∏(1−cj)>0 for the semantic class. Without the instruction layer raising p, the factor (1−p) stays near 1 and the product is dominated by it.
      3. -
    3. Their composition is strictly better than either factor. Because 0<(1−p)<1 and each 0<(1−cj)<1, the product (5) is strictly smaller than (1−p) and strictly smaller than any single (1−cj). Reliability is the product of a soft factor and hard factors, and needs both kinds present.
      4. +
    4. Bound. The per-task residual is at most ε exactly on the region Rε = {(p, q) : (1−p)(1−q) ≤ ε}. Over n tasks, P(≥1 miss) ≤ min(1, nε) whatever the dependence between tasks (union bound). It equals 1−(1−ε)n only if tasks fail independently, and tasks done by one model on one repository need not.
      5. +
    5. Instruction layer alone (q = 0): r = 1−p, so reaching ε needs p ≥ 1−ε from instructions. Raising p does bend the curve: for 30 independent tasks, P(≥1 miss) is 0.958 at p = 0.9 and 0.260 at p = 0.99.
      6. +
    6. Deterministic layer alone (the bare model's p0): reaching ε needs q ≥ 1 − ε/(1−p0).
      7. +
    7. Composition. Adding a check with P(it fires | M, no earlier check fired) > 0 strictly lowers r. Adding a copy of a check that is already present lowers nothing.
    +

    The design claim that survives is a statement about ranges, not an impossibility theorem. Let p0 be the bare model's rate, pmax the best rate instructions can reach, and qmax the best catch rate decidable checks can reach on the misses that matter. Instructions alone leave at least 1−pmax; checks alone leave at least (1−p0)(1−qmax); together they can reach (1−pmax)(1−qmax). So a target ε with (1−pmax)(1−qmax) ≤ ε < min(1−pmax, (1−p0)(1−qmax)) needs both layers and is reachable with them. Whether a real target falls in that range is an empirical question about p0, pmax and qmax, which this paper does not measure.

    □

    -Equation (5) is the probability that the behaviour is both omitted by the agent (the independent event of probability 1−p) and undetected by every one of the k checks (each failing to catch with probability 1−cj, taken as conditionally independent given the miss). Claim 1: set k=0, the empty product is 1, so P=1−p; the n-task bound is the complement of n independent successes, pn. Claim 2: for the semantic-miss class every decidable cj is bounded below 1 (Rice's theorem: non-trivial semantic properties of programs are undecidable), so the product cannot vanish; with p not raised, (1−p) is near 1. Claim 3: multiplying a number in (0,1) by further numbers in (0,1) strictly decreases it below every factor. □ +Equation (5) is the chain rule: a silent miss is a miss (1−p) on which no check fires (1−q). The Fréchet bounds hold for any joint distribution of the checks: no check fires with probability at most that of the most reliable single check missing, and at least 1−Σcj by the union bound. Claim 1: r ≤ ε is the definition of Rε, and P(∪i missi) ≤ Σi P(missi) needs no independence. Claims 2–3: set q = 0, or p = p0, and solve. Claim 4: 1−q falls by the probability that the new check fires on misses no earlier check caught, which is zero for a duplicate. □ +

    What the earlier version got wrong [corrected 2026-09-21]. (i) Its criterion, P(≥1 miss) → 1, also condemns the composed system: whenever every cj < 1 the residual is positive and the same limit holds (0.993 over 1,000 tasks at a residual of 0.005), so it could not separate the layers. (ii) T3 asserts exact detection of its structural class, which, if that class were the target, gives the deterministic layer alone a residual of 0 and contradicts Claim 2. (iii) It said only a factor (1−cj) could bend the failure curve, but raising p does too. (iv) It assumed independent tasks and conditionally independent checks, which the design contradicts (§5.3). (v) Rice's theorem is a worst case over all programs: no single total procedure decides a non-trivial semantic property for every program. It is not a probability bound for a finite repository. That cj < 1 on semantic misses is an empirical premise, not a consequence of Rice.

    What the theorem says in one sentence

    -

    The practitioner's rule — never trust the probability engine's output; verify it — is the statement (1−p)>0. Theorem D turns that intuition into a design mandate: because the soft layer can never drive (1−p) to zero, a deterministic layer must exist to multiply it down; and because the hard layer can never catch the semantic class, the soft layer must exist to shrink what reaches it. The substrate is two-layered not by taste but by theorem.

Theorem D turns that intuition into a design argument: where the soft layer cannot drive (1−p) below the target, a deterministic layer is needed to multiply it down; and where decidable checks cannot catch the semantic class, the soft layer is needed to shrink what reaches them. The substrate is two-layered because of what p and q can reach in practice, not by a theorem that holds for every p, c < 1. [corrected 2026-09-21]

    5 The probabilistic failure model

    Theorem D's equation (5) is worth reading as an engineering instrument, because it explains a lived experience and prices every design choice.

    5.1 Why "it works, then forgets" is a certainty, not bad luck

    -

    With the instruction layer alone, the chance of at least one partial-work incident over n tasks is 1−pn. Even an excellent p=0.9 gives 65% after 10 tasks and 96% after 30. The agent that "usually remembers the docs" is, over a project's lifetime, near-certain to forget them at least once. The failure is geometric, so no degree of prompt-polishing escapes it — only a factor (1−cj) below 1 can bend the curve.

    With the instruction layer alone, the chance of at least one partial-work incident over n tasks is 1−pn. Even an excellent p=0.9 gives 65% after 10 tasks and 96% after 30. The agent that "usually remembers the docs" is, over a project's lifetime, near-certain to forget them at least once. These figures assume tasks fail independently; tasks done by one model on one repository need not, and the dependence-free statement is the union bound P(≥1 miss) ≤ n(1−p). Raising p bends the curve too: at p=0.99 the 30-task figure is 26%, not 96%. Earlier versions said only a factor (1−cj) could do that. [corrected 2026-09-21]

    5.2 Why the deterministic gate is worth exactly one factor

    -

    Add one gate whose target is the decidable signal "code changed and no doc/state artifact changed." That signal is checkable in microseconds and c1≈0.95. With p=0.7, the per-task silent-miss rate falls from 30% to (1−0.7)·(1−0.95)=1.5% — a twentyfold reduction from a twenty-line hook. Crucially the class of surviving misses changes from "forgot the docs entirely" (structural, now caught) to "updated the docs imperfectly" (semantic, handed to review). The gate does not make the model think; it removes an entire failure mode from the model's shoulders.

    +

    Add one gate whose target is the decidable signal "code changed and no doc/state artifact changed." That signal is checkable in microseconds. Suppose, as an illustration rather than a measurement, that 95% of misses show it, so c1≈0.95. With p=0.7, the per-task silent-miss rate falls from 30% to (1−0.7)·(1−0.95)=1.5% — a twentyfold reduction from a twenty-line hook. Crucially the class of surviving misses changes from "forgot the docs entirely" (structural, now caught) to "updated the docs imperfectly" (semantic, handed to review). The gate does not make the model think; it removes an entire failure mode from the model's shoulders.

    +

    But c1 belongs to the agent as much as to the gate. [corrected 2026-09-21] The gate detects its proxy, “code changed and no doc/state artifact changed”, exactly; it does not detect the miss. An agent that edits code and STATE.md but not docs/api.md passes it. If agents touch STATE at rate h, independently of whether they missed a doc, then c1 = 0.95(1−h); at h = 0.9 the residual is 0.27, not 1.5%. The gate also blocks at most once per session (T1), so for every later task in that session c1 = 0.

    5.3 The lattice of gates

    -

    The same classifier can run at three lifecycle points, and (5) shows their catches multiply: a turn-level Stop hook ⊂ a commit-level pre-commit hook ⊂ a PR-level CI job. Each later gate catches what earlier ones missed — the product (5) with k=3. This is also the answer to portability: where hooks are unavailable, the same deterministic check re-binds as a pre-commit hook or a CI step, moving the enforcement point without changing the mathematics.

    +

    The same classifier can run at three lifecycle points: a turn-level Stop hook, a commit-level pre-commit hook, and a PR-level CI job. Earlier versions said (5) made their catches multiply, the product with k=3. They do not. [corrected 2026-09-21] Run on the same diff, the three copies fire together or not at all, so the residual is (1−p)(1−c1), not (1−p)(1−c1)3. With p=0.7 and c1=0.95 the product predicts 3.75×10−5 against a true 0.015, which understates it 400-fold. A later gate adds catches only when it sees something the earlier one could not, such as edits made after the turn ended or a host where the Stop hook never ran. This is also the answer to portability: where hooks are unavailable, the same deterministic check re-binds as a pre-commit hook or a CI step, moving the enforcement point without changing the mathematics.

    7.1 The correctness theorems

    T3 (Soundness of the block signal — no false silence)
    On the first stop of a session with usable git: C is the union of the baseline diff and an untracked-inclusive worktree scan, so every changed path is in C; classification is a total function of path; the row order reaches the block row exactly when code changed and no doc changed. Hence a silent code-only completion is impossible at the session's first completion — the agent must fix the docs or explicitly justify and update STATE, both visible to the developer. □
    +

    T3 is exact for the proxy event (code changed, no doc/state changed) at the session's first stop. It says nothing about the probability that a real miss shows that proxy, which is what Theorem D's c1 measures (§5.2). [corrected 2026-09-21]

    T4 (Loader fidelity under handoff [corrected 2026-09-21])
    If A4 ran and its commit is pushed/pulled, then for any next session on any machine the loader injects σ at start (A5 reads the committed file), so essential(Ki) ∩ σ ⊆ Ki+1(0). Residual risk is exactly selection error in the handoff (what it chose not to write), bounded by the priority order and by DECISIONS catching the durable class. □
    +

    As stated, T4 says only that what the handoff wrote is read back. That is close to vacuous: the substantive continuity claim, essential(Ki) ⊆ σ, is the selection error the proof sets aside. It also holds only if σ fits the loader's 8 KB cap, and a 150-line snapshot at 80 bytes a line does not (A4). Earlier versions called this “continuity under handoff”. [corrected 2026-09-21]

    T5 (Closure termination, A1)

    How the theorems earn Theorem D

    -

    Theorem D says reliability needs a deterministic factor with cj→1 on its target signal. T3 is precisely that guarantee (the block fires exactly on the target signal); T1 and T2 ensure the factor is safe to add (it never loops, never bricks); T5 and T6 ensure the soft-layer machinery it composes with is well-defined (the closure terminates, the router is total); T4 extends the guarantee across the session boundary that F2 attacks. The six local proofs are what make the one global theorem deployable rather than merely true.

    +

    Earlier versions said T3 was the guarantee cj→1 that Theorem D needs. It is narrower. [corrected 2026-09-21] T3 makes the block fire exactly on its proxy signal, but cj is the probability that a real miss shows that proxy, which T3 does not bound (§5.2). What the six results do give: T1 and T2 make the gate safe to add (it never loops, never bricks); T5 makes the closure terminate; T6, with its catch-all arm, makes the router total; T4 says what the handoff wrote is read back if it fits. They make the deterministic layer well-behaved. They do not make it reliable.

    These are the demonstration numbers as first reported. A pre-registered evaluation on data the authors did not build overturned both headline claims: the impact oracle's recall was 0.022 on 759 files in nine real repositories, and on 80 held-out tasks the router's total spend was 20.2% higher than always using the premium tier.

    Theory earns its keep when it runs. Two prototypes instantiate the deterministic layer's two hard functions — the impact closure (A1) and the routing/gate pair (A7 + A6) — and both are evaluated with the honesty the governing discipline demands: a perfect score on a self-built set demonstrates that a rubric can separate cases, never that it is a field benchmark.

    The oracle does not win on F1 — and the paper says so. This version of the paper called its distinguishing property perfect recall and argued from T5 that a reverse-reachability closure run to fixpoint cannot miss a reachable dependent. Both steps failed. T5 guarantees completeness only relative to the relation the closure walks, and on real repositories that relation missed the edges that mattered: recall 0.022 on 759 files in nine repositories, where a grep baseline reached F1 0.437 against the oracle's 0.042.

    The 30-task set is hand-labelled and the thresholds were tuned against it, so these numbers show the rubric can separate the cases — they are not a field benchmark. The cost figures, by contrast, are exact arithmetic on real measured token counts from live calls, and the correctness sub-experiment actually executed the cheaper models' code against test cases (the honesty core: routing down is only a saving if the cheap output is correct). Both prototypes ship as runnable packages with passing test suites.

Rice's theorem says no single procedure decides such properties for every program; that is a worst case, not a bound on how often checks miss in a given repository [corrected 2026-09-21]. In practice the last layer is still needed — tests for behaviour, human review for meaning. The architecture's job is to make that review cheap: everything arrives already-attempted, with an updated / verified / doubts report.

    13 Conclusion

    A language model that writes code is a fixed probabilistic map, and three independent efforts — one from cognition, one from production failures, one from a shipped codebase — converged on the same remedy: wrap it in an external, stateful architecture that supplies the faculties it structurally lacks. This paper showed they describe one object. The impact-awareness faculty is the change-closure fixpoint; the assumption gate is the amnesia equation; and both rest on a single theorem — reliability is the product of a probabilistic instruction layer that raises p<1 and a deterministic interception layer that guarantees a floor, with neither alone sufficient.

    A language model that writes code is a fixed probabilistic map, and three efforts that were not independent of one another — one from cognition, one from production failures, one from a shipped codebase — converged on the same remedy: wrap it in an external, stateful architecture that supplies the faculties it structurally lacks. This paper argued they describe one object. The impact-awareness faculty approximates the change-closure fixpoint; the assumption gate is the amnesia equation; and both rest on one result — the residual silent-miss rate is the product of what a probabilistic instruction layer lets through, 1−p, and what a deterministic interception layer lets through, P(no check fires | miss). Where each factor is bounded away from zero, neither layer alone reaches a small residual. [corrected 2026-09-21]

    That theorem is the formal content of a plain discipline: the output of a probability engine is never to be trusted on its own; trust is earned by an external check. The Qur'anic lens gives that discipline its oldest names — lā taqfu, do not pursue what you do not know; tabayyun, verify the report before you act; al-amāna, the weight of a trust accepted by one who may err. The mathematics says how to build the check. The tradition says why it is owed. The codebase shows it runs.

    Companion artifacts: the three-way crosswalk (JSON + markdown), the graded reference set (Appendix A), and two runnable prototype packages (impact-oracle, router-gate). This synthesis consolidates and does not supersede the v2 Theory → Evidence → Build-Map edition, which carries the empirical evidence layer and the full ecosystem map.

    Corrections (2026-09-21)

    +

    An external deep review of the forgekit repository (2026-09-21) checked this paper's mathematics against its own definitions, its claims about forgekit against the code, and its statistics against the replication package. Several statements were wrong as written. Each is corrected in place above, marked [corrected 2026-09-21], and listed here with the original wording, so nothing is silently rewritten. Every number below was recomputed by research/recompute_corrections.py (pure Python, fixed seeds, printed with each result) from this paper's own worked examples or from the refutation's replication package. The PDF edition predates these corrections.

    +
      +
    1. Theorem D (§4) was circular as stated, and is restated as a bound. It claimed that for any p<1 and any cj<1 “neither layer alone suffices”, using P(≥1 miss) → 1 as the criterion. That criterion condemns the composed system too: with every cj<1 the residual is positive, and at a residual of 0.005 the chance of at least one miss in 1,000 independent tasks is 0.993. T3 also asserts exact detection of its structural class, which would give the deterministic layer alone a residual of 0 on that class and contradict Claim 2. The theorem now bounds the residual by ε on an explicit region of (p, q) and states its dependence assumptions. The word “proves” is withdrawn from the abstract.
      2. +
    2. Raising p bends the failure curve (§5.1). The original said “only a factor (1−cj) below 1 can bend the curve”. For 30 independent tasks, P(≥1 miss) is 0.958 at p = 0.9 and 0.260 at p = 0.99. The 1−pn figures also assume tasks fail independently; tasks done by one model on one repository are correlated, and the dependence-free statement is the union bound.
      3. +
    3. Eq. (5) assumed an independence the design contradicts (§4, §5.3, Fig. 1). The same classifier runs at the Stop hook, at pre-commit and in CI on the same diff, so the copies fire together. The residual is (1−p)·P(no check fires | miss), and (1−p)(1−cmax) for nested checks. With three copies, p = 0.7 and c = 0.95, the old product gives 3.75×10−5; the true residual is 0.015 (a Monte Carlo run with seed 0 and 106 draws also gives 0.0150). That is a 400-fold understatement.
      4. +
    4. cj is not a property of the gate (Def. 5, §5.2, T3, A6). T3 guarantees exact detection of the proxy event, not of the miss. An agent that edits code and STATE.md but not docs/api.md passes the gate. If agents touch STATE at rate h, then c = 0.95(1−h), and at h = 0.9 the residual is 0.27, not 0.015. The gate blocks once per session, so c = 0 for every later task in that session.
      5. +
    5. Definition and proof errors. (a) Anchor identity #1 wrote Δ* as the least fixpoint of X ↦ X ∪ N(X), which is ∅; it is lfp(X ↦ Δ0 ∪ N(X)). (b) The impact oracle is thresholded, depth-10 reachability over the AST relation, a different relation from R: it approximates Δ* and is not Δ*. “This is why the prototype achieves perfect recall” is withdrawn; on nine real repositories its recall was 0.022. (c) T5 gives termination only; completeness relative to R holds by construction. (d) A1 subtracted artifacts from edges (E \ W); it now subtracts from the edges' source artifacts. (e) A3 makes I1 true by definition for couplings grep cannot see (the “retried 3 times” counterexample under A3). (f) T4 was close to vacuous, and A4's 150-line budget does not fit A5's 8 KB cap at 80 bytes a line (12,000 bytes); it is restated as loader fidelity, with that condition. (g) T6 was false because A7 had no catch-all arm; A7 now ends in the fallback forgekit's router uses. (h) Rice's theorem was used as if it bounded cj; it is a worst case over all programs, not a probability bound for a finite repository.
      6. +
    6. The faculty table (§2) disagreed with the whitepaper in all five rows. We keep the whitepaper's derivation: memory from P1 and P3, learning from P2 and P1, imagination from P1 and the token→token form of Eq. 1, self-correction from P2, impact-awareness from P3. It argues each row separately, and it matches what forgekit's bindings address in source/substrate.json: lessons that change no weights (P2), tests trusted over model claims (self-correction's same-weights blind spot, P2), and repository facts surfaced from outside the window (P3). The earlier table had memory P1; learning P2; imagination P1, P3; self-correction P3; impact-awareness P1, P3.
      7. +
    7. Eq. (1) and the amnesia equation disagreed. Eq. 1 read as a deterministic function, its gloss said the output was sampled, and the amnesia equation used argmax. There is now one statement: y ~ pθ(· | x), and greedy decoding, which approximately returns the argmax, is the temperature-0 special case.
      8. +
    8. Priority is conceded here too. The composition law is standard layer-of-protection algebra, and two concurrent preprints (Odds Law and Maestro Order, cited in the refutation paper's related work) derive a strictly more general Bayesian form of it weeks before this paper. research/README.md said priority was conceded “in the paper”, but only the refutation paper's LaTeX source did so, while this paper still said it “proves” the result. What remains ours is narrower: deriving the split from the frozen-map architecture, and testing it against real repositories.
      9. +
    9. The convergence was not independent (abstract, §1, §11, §13, §14). The “four independent arrivals” of §14 (the formal theory, forgekit, hikmah-stack and wisdom-lens) are the same author's work; forgekit and hikmah-stack are both published under the author's GitHub account. The three roads of §1 are not independent either: claude-e2e-kit is forgekit's precursor, and forgekit was built as a binding of this theory. Their agreement shows consistency, not independent evidence that the design is right.
      10. +
    10. Appendix A tally. 9 confirmed, 6 traceable and 0 unverifiable of 15 new sources, not “8 confirmed”. The founding Agent-as-a-Judge paper was added on the citations track's recommendation after the count was written.
      11. +
    11. The prototype results in §10 were refuted before this correction, and the section now says so. The impact oracle's “perfect recall” was measured on five mutations of a ten-file package the authors wrote; on 759 evaluated files in nine real repositories its recall was 0.022, and a grep baseline scored F1 0.437 against its 0.042. The router's “62.1% real cost saved” was measured on the 30 tasks its thresholds were tuned on; on 80 held-out tasks the pipeline's total spend was 20.2% higher than always using the premium tier. Per output the judge accepted, it cost $1.06 against always-premium's $1.76, but only 6 and 3 of 64 outputs were accepted, so neither figure is stable. The details are in the extended preprint and the refutation paper.

    An external review found that Theorem D was circular as stated, that Eq. (5) assumed an independence the design contradicts, that several definitions and proofs were wrong, that one sentence still claimed the prototype’s perfect recall, and that some statistical inferences in §10 were stronger than the data support. The theory sections are therefore no longer unchanged from the synthesis edition.

    A large language model used for coding is a fixed probabilistic map, y = fθ(x): stateless, frozen, and bounded in context. Three research efforts converged, independently, on the same conclusion — that the remedy is not a better prompt or a bigger model but an external, stateful architecture wrapped around the frozen core. This paper proves they are describing one object. We show that the substrate's impact-awareness faculty and the framework's change-closure fixpoint Δ* are the same mathematics; that the assumption gate and the amnesia equation assumption ≈ argmax P(convention | training) are the same phenomenon; and that both reduce to a single two-layer duality: a probabilistic instruction layer that raises the probability p<1 of correct behaviour, and a deterministic interception layer that guarantees a floor. The central theorem states that neither layer alone can make an agent reliable — a direct formalization of the discipline never trust the output of a probabilistic engine; earn trust with an external check. We give definitions, the duality theorem with proof, a unified seven-algorithm task loop, the probabilistic failure model P(≥1 miss)=1−pn, and carry through the six correctness theorems of the reliability framework. Two prototypes — an impact oracle and a complexity-router/assumption-gate — instantiate the deterministic layer and are evaluated honestly. The forgekit / claude-e2e-kit codebase is the deployed binding. The Qur'anic lens supplies the vocabulary of epistemic obligation (tabayyun, amāna, lā taqfu) that names why each safeguard is mandatory rather than optional.

    A large language model used for coding is a fixed probabilistic map, y = fθ(x): stateless, frozen, and bounded in context. Three bodies of work, developed separately from different starting points, converged on the same conclusion — that the remedy is not a better prompt or a bigger model but an external, stateful architecture wrapped around the frozen core. This paper argues [corrected 2026-09-21] they are describing one object; their agreement is consistency rather than independent evidence, since forgekit was built as a binding of the other two [corrected 2026-09-21]. We show that the substrate's impact-awareness faculty and the framework's change-closure fixpoint Δ* have the same shape, the oracle approximating the fixpoint over a different relation [corrected 2026-09-21]; that the assumption gate and the amnesia equation assumption ≈ argmax P(convention | training) are the same phenomenon; and that both reduce to a single two-layer duality: a probabilistic instruction layer that raises the probability p<1 of correct behaviour, and a deterministic interception layer that multiplies down what escapes it. The central result, restated in the 2026-09-21 corrections as a bound on the residual over an explicit region of (instruction-following, catch) probabilities rather than as an impossibility theorem [corrected 2026-09-21], is a formalization of the discipline never trust the output of a probabilistic engine; earn trust with an external check. The composition law itself is standard layer-of-protection algebra, and two concurrent preprints derived a strictly more general Bayesian form of it first; we concede priority [corrected 2026-09-21]. We give definitions, the duality result, a unified seven-algorithm task loop, the probabilistic failure model P(≥1 miss)=1−pn (for independent tasks), and carry through the six correctness theorems of the reliability framework. Two prototypes — an impact oracle and a complexity-router/assumption-gate — instantiate the deterministic layer; both of their headline results were later refuted on data the authors did not build [corrected 2026-09-21]. The forgekit / claude-e2e-kit codebase is the deployed binding. The Qur'anic lens supplies the vocabulary of epistemic obligation (tabayyun, amāna, lā taqfu) that names why each safeguard is mandatory rather than optional.

    Two of these three “identities” are weaker than this callout says: the impact oracle approximates Δ* rather than computing it (§3.2), and the duality is a bound over a region of parameters, not a theorem for every p, c < 1 (§4). See the Corrections. [corrected 2026-09-21]

    The synthesis also inherits a governing discipline, stated plainly by the practitioner who commissioned this work: AI output is a mathematically calculated probability; it must never be trusted blindly; for the same prompt it can give a different answer, so use only the capability it is genuinely best at, and earn trust with an external check. We will see that this sentence is not a slogan but the informal statement of the central theorem — the quantity (1−p)>0 that forces a deterministic layer to exist.

    The critical word is external. Because θ is frozen (P2) and context is bounded (P3), none of these can be fixed by prompting harder or by fine-tuning alone. The architecture must live around the model, hold state outside it, and enforce behaviour the model cannot be relied upon to produce on its own. The rest of this paper makes "cannot be relied upon" precise and shows what "enforce" must therefore mean.

    The substrate's Impact Oracle computes a file's blast radius by reverse reachability on the dependency graph, which has the same shape as the closure (4). It is not the same object. The oracle adds a real-valued confidence that decays with graph distance, keeps only what clears a threshold, stops at depth 10, and walks the AST import/call relation rather than the framework's R (which also carries documentation and declared edges). So it approximates Δ* over a different relation. Earlier versions said the two were the same computation and that this was why the prototype achieved perfect recall. That inference was wrong: completeness relative to a relation says nothing about whether the relation holds the edges that matter, and on nine real repositories the oracle's recall was 0.022 (§10).

    4 The central result — the two-layer duality theorem

    A substrate's behaviour-shaping is partitioned into two layers over the frozen model:

    • The probabilistic layer (Π3): standing instructions loaded into context — CLAUDE.md, rules, skills, protocol cards. Let p = P(the agent performs the required behaviour on a task — e.g. the full closure Δ* — under the instruction layer alone).
      • -
    • The deterministic layer (Π2): code executed at fixed lifecycle points independent of the model's choices — hooks that inject state, or that block a turn. A deterministic check j catches a target miss with probability cj, and for a decidable structural signal cj → 1.

    • The deterministic layer (Π2): code executed at fixed lifecycle points independent of the model's choices — hooks that inject state, or that block a turn. A deterministic check j fires with probability cj = P(check j fires | miss). A decidable check detects its proxy signal exactly, but cj is the probability that a miss shows that proxy. That depends on the agent's behaviour as well as on the check, so it is not a property of the gate alone (§5.2). [corrected 2026-09-21]

    -
    Theorem D (Two-layer duality — neither layer alone suffices)
    -

    Let a task require a behaviour whose omission is a silent miss. Under the instruction layer alone the per-task silent-miss probability is 1−p; under a deterministic layer of k checks the residual silent-miss probability is

    -
    (5)P(silent miss) = (1−p) · ∏j=1..k (1−cj).
    -

    Then, for any model whose instruction-following is imperfect (p<1) and any deterministic layer that is not omniscient (cj<1 for every j):

    +
    Theorem D (Two-layer duality, restated as a bound [corrected 2026-09-21])
    +

    Let a task require a behaviour whose omission is a silent miss. Let M be the event that the agent omits it under the instruction layer, so P(M) = 1−p, and let q = P(at least one of the k checks fires | M). The per-task residual is exactly

    +
    (5)r = P(silent miss) = (1−p) · (1−q) = (1−p) · P(no check fires | M).
    +

    With cj = P(check j fires | M), and no independence assumption, max(0, 1−Σjcj) ≤ 1−q ≤ 1−maxjcj (Fréchet bounds). The product (1−p)·∏j(1−cj), which earlier versions gave as Eq. (5), is the special case in which the checks fire independently given the miss. When the checks are nested, for example the same classifier run at several points on the same diff, r = (1−p)(1−cmax).

    +

    Then:

      -
    1. The probabilistic layer alone cannot reach reliability. With k=0, P(silent miss)=1−p>0, and over n tasks P(≥1 miss)=1−pn → 1. No amount of instruction-writing removes the residual, because instructions are context, not enforcement.
      2. -
    2. The deterministic layer alone cannot reach reliability either. A decidable check bounds only the structural signal it was built to detect; semantic correctness is undecidable (§12), so ∏(1−cj)>0 for the semantic class. Without the instruction layer raising p, the factor (1−p) stays near 1 and the product is dominated by it.
      3. -
    3. Their composition is strictly better than either factor. Because 0<(1−p)<1 and each 0<(1−cj)<1, the product (5) is strictly smaller than (1−p) and strictly smaller than any single (1−cj). Reliability is the product of a soft factor and hard factors, and needs both kinds present.
      4. +
    4. Bound. The per-task residual is at most ε exactly on the region Rε = {(p, q) : (1−p)(1−q) ≤ ε}. Over n tasks, P(≥1 miss) ≤ min(1, nε) whatever the dependence between tasks (union bound). It equals 1−(1−ε)n only if tasks fail independently, and tasks done by one model on one repository need not.
      5. +
    5. Instruction layer alone (q = 0): r = 1−p, so reaching ε needs p ≥ 1−ε from instructions. Raising p does bend the curve: for 30 independent tasks, P(≥1 miss) is 0.958 at p = 0.9 and 0.260 at p = 0.99.
      6. +
    6. Deterministic layer alone (the bare model's p0): reaching ε needs q ≥ 1 − ε/(1−p0).
      7. +
    7. Composition. Adding a check with P(it fires | M, no earlier check fired) > 0 strictly lowers r. Adding a copy of a check that is already present lowers nothing.
    +

    The design claim that survives is a statement about ranges, not an impossibility theorem. Let p0 be the bare model's rate, pmax the best rate instructions can reach, and qmax the best catch rate decidable checks can reach on the misses that matter. Instructions alone leave at least 1−pmax; checks alone leave at least (1−p0)(1−qmax); together they can reach (1−pmax)(1−qmax). So a target ε with (1−pmax)(1−qmax) ≤ ε < min(1−pmax, (1−p0)(1−qmax)) needs both layers and is reachable with them. Whether a real target falls in that range is an empirical question about p0, pmax and qmax, which this paper does not measure.

    □

    -Equation (5) is the probability that the behaviour is both omitted by the agent (the independent event of probability 1−p) and undetected by every one of the k checks (each failing to catch with probability 1−cj, taken as conditionally independent given the miss). Claim 1: set k=0, the empty product is 1, so P=1−p; the n-task bound is the complement of n independent successes, pn. Claim 2: for the semantic-miss class every decidable cj is bounded below 1 (Rice's theorem: non-trivial semantic properties of programs are undecidable), so the product cannot vanish; with p not raised, (1−p) is near 1. Claim 3: multiplying a number in (0,1) by further numbers in (0,1) strictly decreases it below every factor. □ +Equation (5) is the chain rule: a silent miss is a miss (1−p) on which no check fires (1−q). The Fréchet bounds hold for any joint distribution of the checks: no check fires with probability at most that of the most reliable single check missing, and at least 1−Σcj by the union bound. Claim 1: r ≤ ε is the definition of Rε, and P(∪i missi) ≤ Σi P(missi) needs no independence. Claims 2–3: set q = 0, or p = p0, and solve. Claim 4: 1−q falls by the probability that the new check fires on misses no earlier check caught, which is zero for a duplicate. □ +

    What the earlier version got wrong [corrected 2026-09-21]. (i) Its criterion, P(≥1 miss) → 1, also condemns the composed system: whenever every cj < 1 the residual is positive and the same limit holds (0.993 over 1,000 tasks at a residual of 0.005), so it could not separate the layers. (ii) T3 asserts exact detection of its structural class, which, if that class were the target, gives the deterministic layer alone a residual of 0 and contradicts Claim 2. (iii) It said only a factor (1−cj) could bend the failure curve, but raising p does too. (iv) It assumed independent tasks and conditionally independent checks, which the design contradicts (§5.3). (v) Rice's theorem is a worst case over all programs: no single total procedure decides a non-trivial semantic property for every program. It is not a probability bound for a finite repository. That cj < 1 on semantic misses is an empirical premise, not a consequence of Rice.

    The practitioner's rule — never trust the probability engine's output; verify it — is the statement (1−p)>0. Theorem D turns that intuition into a design mandate: because the soft layer can never drive (1−p) to zero, a deterministic layer must exist to multiply it down; and because the hard layer can never catch the semantic class, the soft layer must exist to shrink what reaches it. The substrate is two-layered not by taste but by theorem.

    Add one gate whose target is the decidable signal "code changed and no doc/state artifact changed." That signal is checkable in microseconds. Suppose, as an illustration rather than a measurement, that 95% of misses show it, so c1≈0.95. With p=0.7, the per-task silent-miss rate falls from 30% to (1−0.7)·(1−0.95)=1.5% — a twentyfold reduction from a twenty-line hook.

    But c1 belongs to the agent as much as to the gate. [corrected 2026-09-21] The gate detects its proxy, “code changed and no doc/state artifact changed”, exactly; it does not detect the miss. An agent that edits code and STATE.md but not docs/api.md passes it. If agents touch STATE at rate h, independently of whether they missed a doc, then c1 = 0.95(1−h); at h = 0.9 the residual is 0.27, not 1.5%. The gate also blocks at most once per session (T1), so for every later task in that session c1 = 0.

    The same classifier can run at three lifecycle points, and (5) shows their catches multiply: a turn-level Stop hook ⊂ a commit-level pre-commit hook ⊂ a PR-level CI job. Each later gate catches what earlier ones missed — the product (5) with k=3. This is also the answer to portability: where hooks are unavailable, the same deterministic check re-binds as a pre-commit hook or a CI step, moving the enforcement point without changing the mathematics.

    The same classifier can run at three lifecycle points: a turn-level Stop hook, a commit-level pre-commit hook, and a PR-level CI job. Earlier versions said (5) made their catches multiply, the product with k=3. They do not. [corrected 2026-09-21] Run on the same diff, the three copies fire together or not at all, so the residual is (1−p)(1−c1), not (1−p)(1−c1)3. With p=0.7 and c1=0.95 the product predicts 3.75×10−5 against a true 0.015, which understates it 400-fold. A later gate adds catches only when it sees something the earlier one could not, such as edits made after the turn ended or a host where the Stop hook never ran. This is also the answer to portability: where hooks are unavailable, the same deterministic check re-binds as a pre-commit hook or a CI step, moving the enforcement point without changing the mathematics.

    T3 (Soundness of the block signal — no false silence)
    On the first stop of a session with usable git: C is the union of the baseline diff and an untracked-inclusive worktree scan, so every changed path is in C; classification is a total function of path; the row order reaches the block row exactly when code changed and no doc changed. Hence a silent code-only completion is impossible at the session's first completion — the agent must fix the docs or explicitly justify and update STATE, both visible to the developer. □
    +

    T3 is exact for the proxy event (code changed, no doc/state changed) at the session's first stop. It says nothing about the probability that a real miss shows that proxy, which is what Theorem D's c1 measures (§5.2). [corrected 2026-09-21]

    T4 (Loader fidelity under handoff [corrected 2026-09-21])
    If A4 ran and its commit is pushed/pulled, then for any next session on any machine the loader injects σ at start (A5 reads the committed file), so essential(Ki) ∩ σ ⊆ Ki+1(0). Residual risk is exactly selection error in the handoff (what it chose not to write), bounded by the priority order and by DECISIONS catching the durable class. □
    +

    As stated, T4 says only that what the handoff wrote is read back. That is close to vacuous: the substantive continuity claim, essential(Ki) ⊆ σ, is the selection error the proof sets aside. It also holds only if σ fits the loader's 8 KB cap, and a 150-line snapshot at 80 bytes a line does not (A4). Earlier versions called this “continuity under handoff”. [corrected 2026-09-21]

    How the theorems earn Theorem D

    -

    Theorem D says reliability needs a deterministic factor with cj→1 on its target signal. T3 is precisely that guarantee (the block fires exactly on the target signal); T1 and T2 ensure the factor is safe to add (it never loops, never bricks); T5 and T6 ensure the soft-layer machinery it composes with is well-defined (the closure terminates, the router is total); T4 extends the guarantee across the session boundary that F2 attacks. The six local proofs are what make the one global theorem deployable rather than merely true.

    +

    Earlier versions said T3 was the guarantee cj→1 that Theorem D needs. It is narrower. [corrected 2026-09-21] T3 makes the block fire exactly on its proxy signal, but cj is the probability that a real miss shows that proxy, which T3 does not bound (§5.2). What the six results do give: T1 and T2 make the gate safe to add (it never loops, never bricks); T5 makes the closure terminate; T6, with its catch-all arm, makes the router total; T4 says what the handoff wrote is read back if it fits. They make the deterministic layer well-behaved. They do not make it reliable.

Earlier versions called this an independent team's work and “the strongest available evidence that the architecture is discovered, not invented”. It is not independent: claude-e2e-kit is forgekit's precursor, and forgekit was built as a binding of this theory, so the agreement shows the framings are consistent; it is not independent evidence that the architecture is right.

    13 Conclusion

    -

    A language model that writes code is a fixed probabilistic map, and three independent efforts — one from cognition, one from production failures, one from a shipped codebase — converged on the same remedy: wrap it in an external, stateful architecture that supplies the faculties it structurally lacks. This paper showed they describe one object. The impact-awareness faculty is the change-closure fixpoint; the assumption gate is the amnesia equation; and both rest on a single theorem — reliability is the product of a probabilistic instruction layer that raises p<1 and a deterministic interception layer that guarantees a floor, with neither alone sufficient.

This paper argued they describe one object. The impact-awareness faculty approximates the change-closure fixpoint; the assumption gate is the amnesia equation; and both rest on one result — the residual silent-miss rate is the product of what a probabilistic instruction layer lets through, 1−p, and what a deterministic interception layer lets through, P(no check fires | miss). Where each factor is bounded away from zero, neither layer alone reaches a small residual. [corrected 2026-09-21]

    The limit this edition discovered the hard way

    That theorem is the formal content of a plain discipline: the output of a probability engine is never to be trusted on its own; trust is earned by an external check. The Qur'anic lens gives that discipline its oldest names — lā taqfu, do not pursue what you do not know; tabayyun, verify the report before you act; al-amāna, the weight of a trust accepted by one who may err. The mathematics says how to build the check. The tradition says why it is owed. The codebase shows it runs.

    Companion artifacts: the three-way crosswalk (JSON + markdown), the graded reference set (Appendix A), and two runnable prototype packages (impact-oracle, router-gate). This synthesis consolidates and does not supersede the v2 Theory → Evidence → Build-Map edition, which carries the empirical evidence layer and the full ecosystem map.

    Corrections (2026-09-21)

    +

    An external deep review of the forgekit repository (2026-09-21) checked this paper's mathematics against its own definitions, its claims about forgekit against the code, and its statistics against the replication package. Several statements were wrong as written. Each is corrected in place above, marked [corrected 2026-09-21], and listed here with the original wording, so nothing is silently rewritten. Every number below was recomputed by research/recompute_corrections.py (pure Python, fixed seeds, printed with each result) from this paper's own worked examples or from the refutation's replication package. The PDF edition predates these corrections.

    +
      +
    1. Theorem D (§4) was circular as stated, and is restated as a bound. It claimed that for any p<1 and any cj<1 “neither layer alone suffices”, using P(≥1 miss) → 1 as the criterion. That criterion condemns the composed system too: with every cj<1 the residual is positive, and at a residual of 0.005 the chance of at least one miss in 1,000 independent tasks is 0.993. T3 also asserts exact detection of its structural class, which would give the deterministic layer alone a residual of 0 on that class and contradict Claim 2. The theorem now bounds the residual by ε on an explicit region of (p, q) and states its dependence assumptions. The word “proves” is withdrawn from the abstract.
      2. +
    2. Raising p bends the failure curve (§5.1). The original said “only a factor (1−cj) below 1 can bend the curve”. For 30 independent tasks, P(≥1 miss) is 0.958 at p = 0.9 and 0.260 at p = 0.99. The 1−pn figures also assume tasks fail independently; tasks done by one model on one repository are correlated, and the dependence-free statement is the union bound.
      3. +
    3. Eq. (5) assumed an independence the design contradicts (§4, §5.3, Fig. 1). The same classifier runs at the Stop hook, at pre-commit and in CI on the same diff, so the copies fire together. The residual is (1−p)·P(no check fires | miss), and (1−p)(1−cmax) for nested checks. With three copies, p = 0.7 and c = 0.95, the old product gives 3.75×10−5; the true residual is 0.015 (a Monte Carlo run with seed 0 and 106 draws also gives 0.0150). That is a 400-fold understatement.
      4. +
    4. cj is not a property of the gate (Def. 5, §5.2, T3, A6). T3 guarantees exact detection of the proxy event, not of the miss. An agent that edits code and STATE.md but not docs/api.md passes the gate. If agents touch STATE at rate h, then c = 0.95(1−h), and at h = 0.9 the residual is 0.27, not 0.015. The gate blocks once per session, so c = 0 for every later task in that session.
      5. +
    5. Definition and proof errors. (a) Anchor identity #1 wrote Δ* as the least fixpoint of X ↦ X ∪ N(X), which is ∅; it is lfp(X ↦ Δ0 ∪ N(X)). (b) The impact oracle is thresholded, depth-10 reachability over the AST relation, a different relation from R: it approximates Δ* and is not Δ*. “This is why the prototype achieves perfect recall” is withdrawn; on nine real repositories its recall was 0.022. (c) T5 gives termination only; completeness relative to R holds by construction. (d) A1 subtracted artifacts from edges (E \ W); it now subtracts from the edges' source artifacts. (e) A3 makes I1 true by definition for couplings grep cannot see (the “retried 3 times” counterexample under A3). (f) T4 was close to vacuous, and A4's 150-line budget does not fit A5's 8 KB cap at 80 bytes a line (12,000 bytes); it is restated as loader fidelity, with that condition. (g) T6 was false because A7 had no catch-all arm; A7 now ends in the fallback forgekit's router uses. (h) Rice's theorem was used as if it bounded cj; it is a worst case over all programs, not a probability bound for a finite repository.
      6. +
    6. The faculty table (§2) disagreed with the whitepaper in all five rows. We keep the whitepaper's derivation: memory from P1 and P3, learning from P2 and P1, imagination from P1 and the token→token form of Eq. 1, self-correction from P2, impact-awareness from P3. It argues each row separately, and it matches what forgekit's bindings address in source/substrate.json: lessons that change no weights (P2), tests trusted over model claims (self-correction's same-weights blind spot, P2), and repository facts surfaced from outside the window (P3). The earlier table had memory P1; learning P2; imagination P1, P3; self-correction P3; impact-awareness P1, P3.
      7. +
    7. Eq. (1) and the amnesia equation disagreed. Eq. 1 read as a deterministic function, its gloss said the output was sampled, and the amnesia equation used argmax. There is now one statement: y ~ pθ(· | x), and greedy decoding, which approximately returns the argmax, is the temperature-0 special case.
      8. +
    8. Priority is conceded here too. The composition law is standard layer-of-protection algebra, and two concurrent preprints (Odds Law and Maestro Order, cited in the refutation paper's related work) derive a strictly more general Bayesian form of it weeks before this paper. research/README.md said priority was conceded “in the paper”, but only the refutation paper's LaTeX source did so, while this paper still said it “proves” the result. What remains ours is narrower: deriving the split from the frozen-map architecture, and testing it against real repositories.
      9. +
    9. The convergence was not independent (abstract, §1, §11, §13). Earlier versions called the three roads of §1 independent and the kit “an independent team”'s work. claude-e2e-kit is forgekit's precursor, and forgekit was built as a binding of this theory. Their agreement shows consistency, not independent evidence that the design is right.
      10. +
    10. Appendix A tally. 9 confirmed, 6 traceable and 0 unverifiable of 15 new sources, not “8 confirmed”. The founding Agent-as-a-Judge paper was added on the citations track's recommendation after the count was written.

      • 801 vs 759. 801 files were labelled; the metrics are over 759 of them, because the pre-registered cap of 200 files per repository cut pytest from 242 to 200.
        • +
      • File-level intervals understate uncertainty. Every ground-truth pair is mirrored (all 20,144 pairs among the 801 labelled files have both ends labelled and appear from both sides), and files cluster in nine repositories. Resampling repositories instead of files (seed 1234, 20,000 resamples), the oracle's precision interval is [0.15, 0.91] (file-level: [0.27, 0.57]) and its recall interval [0.0005, 0.052] (file-level: [0.012, 0.033]). The refutation survives: oracle F1 [0.001, 0.093] against grep's [0.381, 0.539], and the paired difference in F1 (grep minus oracle) is [0.342, 0.517].
        • +
      • “The repaired oracle beats the baseline” is not established. On the three held-out repositories the point estimate favours it: F1 is higher by 0.044 at the canonical threshold 0.02 and by 0.057 at 0.10, and at 0.10, where per-repository counts exist, all three repositories agree in sign (+0.114 loguru, +0.131 requests, +0.033 pytest). But three out of three gives a one-sided sign-test p of 0.125, pytest supplies 71% of the held-out pairs, and the separately computed file-level F1 intervals overlap ([0.382, 0.446] and [0.332, 0.405]).
        • +
      • The split was not clean for structural choices. The eight numeric parameters were fit on the six tuning repositories only, but the choice of which relations to add (sibling, forward) came from the failure analysis pooled over all nine, held-out repositories included.
        • +
      • The labels come from one model. The gold labels and the “independent” second labelling pass were both produced by the same model (claude-sonnet-5) with differently worded prompts, on a 30-task subset; that model is also the correctness judge and the mid-tier executor. κ measures how robust the labels are to prompt wording, not whether they are valid.
        • +
      • The cost inversion is largely mechanical. 58 of 64 tasks fail at every tier, and always-premium is judged correct on only 3 of 64, so escalation pays for every tier on almost every task. Per output the judge accepted, the pipeline cost $1.06 against always-premium's $1.76 (about 40% lower), from 6 and 3 accepted outputs; neither figure is stable at those counts.
        • +
      • The ceiling does not show that 96.8% of misses are fixable. It counts pairs joined by some static path in the oracle's graph. Co-change is symmetric while impact is directional, and no control measured how many random pairs are connected in the same dense graph. It bounds what a static method could reach.

    A Cognitive Substrate for Coding Agents

    A first‑principles design study, grounded in field evidence. The five faculties are argued from the shape of a frozen model and grounded in 32 primary sources (memory‑augmentation, continual‑learning, self‑correction, world‑model, and program‑analysis literatures). This edition adds an evidence layer — twelve load‑bearing pain‑point statistics independently re‑grounded from primary sources and graded confirmed / vendor‑reported / unverifiable — six mechanisms (routing, assumption gate, decomposition, goal‑anchoring, anti‑over‑engineering, inline verification), a build‑opportunity map against the real 2026 Claude‑Code stack, and a second prototype (a complexity‑aware router + assumption gate, evaluated live on real models). An epistemological and ethical lens drawn from Qur'anic sources runs throughout, used as design framing, never as technical authority.  |  Companion artifacts: evidence map, ecosystem map, gap‑map, reference list, Qur'anic‑lens table, and two runnable packages (impact‑oracle, router‑gate). +
    +
    Status: both prototype results in this edition were refuted · corrections 2026-09-21
    +

    This edition was written before any real-repository evaluation existed. A later pre-registered evaluation (research/empirical-refutation/) overturned both prototype claims: the impact oracle’s recall was 0.022, not 1.00, on 759 files in nine open-source repositories, and on 80 held-out tasks the router’s total spend was 20.2% higher than always using the premium tier, not 62.1% lower. An external review (2026-09-21) also found a misquoted statistic, a wrong worst-case cost, and an inconsistency between Eq. (1) and M2. Corrections are made in place, marked [corrected 2026-09-21] or [refuted], and listed with the original wording in Corrections. The theory sections remain the programme’s working framework; the prototype numbers do not. The PDF edition predates these corrections.

    Abstract

    -

    A large language model at inference time is, mathematically, a fixed function y = fθ(x) with frozen parameters θ and a bounded input window. From this single fact, five apparent “cognitive” deficits of a coding agent follow as structural consequences, not incidental weaknesses: it cannot remember across sessions, cannot learn from outcomes, cannot imagine the consequences of an action before taking it, cannot reliably correct itself, and does not know what already exists in a codebase or what an edit will affect. We show that neither better prompting nor additional tools (skills, MCP servers) remove these deficits, because they leave fθ and the open‑loop pipeline intact. We then specify a cognitive substrate: an external architecture that keeps the LLM frozen but re‑wraps its input→process→output loop into a closed, stateful cycle over persistent stores — an episodic/semantic memory, an online‑updatable learning layer, a consequence simulator, a metacognitive verification gate, and a persistent structural model of the codebase — all under an explicit stewardship boundary. For each faculty we identify precisely what the existing literature solves and what residual gap remains for a coding agent. To turn the weakest‑evidenced claim into something testable, we build and evaluate the impact‑awareness faculty as a runnable prototype: a Codebase World‑Model that parses a repository into a persistent dependency graph, and an Impact Oracle that predicts the blast radius of a proposed edit. Against mutation‑derived ground truth, the oracle is the only method that never misses an affected file (recall = 1.00 across five tested edits), where a text‑search baseline misses transitive dependents and an edited‑file‑only baseline misses 47% of impact. Throughout, a Qur'anic epistemic lens supplies the design's vocabulary of obligation — know what exists before acting (2:31–32), verify before you act (49:6), pursue not that of which you have no knowledge (17:36), and hold what you can damage as a trust (33:72).

Edges capture five structural relations: imports, calls, inherits, references, contains. The graph is persisted to disk keyed by a per‑file content hash, so an unchanged file is never re‑parsed — the “persistent memory of what already exists,” incremental by construction.

    The oracle does not dominate every metric, and the paper is stronger for saying so. On F1 at the default threshold, the grep baseline (0.79) slightly edges the oracle (0.75). What the oracle uniquely provides is guaranteed recall: across all five mutations it never once missed a file that actually broke, whereas grep missed transitive dependents (a caller that never mentions the symbol by name) and edited‑file‑only missed 47% of real impact. For the question that matters when you are about to change production code — “show me everything that could break” — a false negative (a silent breakage) is far more costly than a false positive (an extra file to glance at), and only the structural oracle drives false negatives to zero. Its precision, moreover, is tunable: Figure 5(right) shows the operating point can be moved along the curve, where neither text baseline offers such a control.

It did not on real code: on 759 files in nine open‑source repositories, 91% of files received zero recall, because the graph walked only reverse edges and mis‑built one package layout. Its precision, moreover, is tunable: Figure 5(right) shows the operating point can be moved along the curve, where neither text baseline offers such a control.

    It also scales. Beyond the toy package, the same parser handled real standard‑library code: it built a 303‑node graph of the json package in 18 ms and a 1,903‑node graph of the http package in 91 ms, answering impact queries in under a millisecond. The approach is not a toy that only works on toys; it is a mature technique that simply had not been placed in the agent's loop.

    13 Conclusion

    -

    The faculties a coding agent seems to lack — memory, learning, imagination, self‑correction, impact‑awareness — are not deficiencies of knowledge that scale will cure. They are structural consequences of what a frozen transformer is: a stateless map with fixed weights and a bounded window (Eq. 1, P1–P3). Because they follow from the shape of the loop, they cannot be prompted or tooled away; they can only be removed by re‑wrapping the loop into a closed, stateful cycle over persistent stores, with the model left frozen inside it (Eq. 2, Fig. 1–2). We specified that substrate faculty by faculty, said honestly which parts are open research and which are engineering, and — for the one faculty that is buildable today — shipped a running impact oracle that, against independent ground truth, never misses an affected file where the strategies a context‑bounded agent actually uses miss up to half. The Qur'anic lens gave the work its spine of obligation: know what exists before you act, verify what you are told, and hold what you can damage as a trust. Those are not just good engineering defaults; here they are the architecture. The next step is to build the memory and learning layers against the same discipline — anchored to what can be verified, not to what the model says of itself — and to evaluate the whole loop on real repositories with real histories.

    Corrections (2026-09-21)

    +

    This edition was published before its prototypes were tested on data we did not build. The refutation (research/empirical-refutation/) reports that test; an external deep review of the forgekit repository (2026-09-21) found the further errors below. Each is corrected in place above and listed here with the original wording, so nothing is silently rewritten. Numbers were recomputed by research/recompute_corrections.py from the refutation’s replication package. The PDF edition predates these corrections.

    +
      +
    1. The impact oracle’s recall (abstract, §8, §12, §13). The edition said the oracle “never misses an affected file” and offered “guaranteed recall”. That held on five mutations of a ten‑file package we wrote. On 759 files in nine open‑source repositories its recall was 0.022, 91% of files got zero recall, and a grep baseline scored F1 0.437 against its 0.042. The graph under‑approximated rather than erring toward inclusion, so §7.1’s “sound over‑approximations” and “exact‑analysis instance” are withdrawn.
      2. +
    2. The routing cost saving (§9). The 62.1% saving was measured on the 30 tasks the thresholds were tuned on. On 80 held‑out tasks, counting every escalation, total spend was 20.2% higher than always‑premium. Per output a judge accepted, the pipeline cost $1.06 and always‑premium $1.76, from 6 and 3 accepted outputs of 64; 58 of the 64 tasks failed at every tier.
      3. +
    3. M1’s worst case (§6). “The worst case is a cheap attempt plus a premium attempt” is wrong for a ladder that escalates one tier at a time: the worst case is the sum over every tier from the routed one up, which exceeds always‑premium. That is the mechanism behind the −20.2%.
      4. +
    4. Eq. (1) and M2 disagreed. Eq. (1) wrote y as a deterministic function, the text said y is sampled, and M2 said the model computes the argmax. There is now one statement: y is a draw from pθ(· | x), and greedy decoding, approximately the argmax, is the temperature‑0 special case.
      5. +
    5. A misquoted statistic (§4.2). Faros reports “31.3% more PRs merged with no review” (a relative increase between low‑ and high‑adoption quarters), as the evidence appendix (C7) already says. The body said “31.3% of PRs merged with no review”.
      6. +
    6. The faculty table (§2) is unchanged here, and is now the canonical one. The formal synthesis had a different “follows from” column in all five rows; it has been brought into line with this table, which argues each row and matches what forgekit’s bindings address.

    A Cognitive Substrate for Coding Agents

The five faculties are argued from the shape of a frozen model and grounded in 32 primary sources (memory‑augmentation, continual‑learning, self‑correction, world‑model, and program‑analysis literatures). This edition adds an evidence layer — twelve load‑bearing pain‑point statistics independently re‑grounded from primary sources and graded confirmed / vendor‑reported / unverifiable — six mechanisms (routing, assumption gate, decomposition, goal‑anchoring, anti‑over‑engineering, inline verification), a build‑opportunity map against the real 2026 Claude‑Code stack, and a second prototype (a complexity‑aware router + assumption gate, evaluated live on real models). An epistemological and ethical lens drawn from Qur'anic sources runs throughout, used as design framing, never as technical authority.  |  Companion artifacts: evidence map, ecosystem map, gap‑map, reference list, Qur'anic‑lens table, and two runnable packages (impact‑oracle, router‑gate).

    Abstract

    -

    A large language model at inference time is, mathematically, a fixed function y = fθ(x) with frozen parameters θ and a bounded input window. From this single fact, five apparent “cognitive” deficits of a coding agent follow as structural consequences, not incidental weaknesses: it cannot remember across sessions, cannot learn from outcomes, cannot imagine the consequences of an action before taking it, cannot reliably correct itself, and does not know what already exists in a codebase or what an edit will affect. We show that neither better prompting nor additional tools (skills, MCP servers) remove these deficits, because they leave fθ and the open‑loop pipeline intact.

    A large language model at inference time is, mathematically, a fixed function y = fθ(x) with frozen parameters θ and a bounded input window. From this single fact, five apparent “cognitive” deficits of a coding agent follow as structural consequences, not incidental weaknesses: it cannot remember across sessions, cannot learn from outcomes, cannot imagine the consequences of an action before taking it, cannot reliably correct itself, and does not know what already exists in a codebase or what an edit will affect. We show that neither better prompting nor additional tools (skills, MCP servers) remove these deficits, because they leave fθ and the open‑loop pipeline intact.

    World‑model. A parser walks a repository with Python's ast module and builds a directed graph whose nodes are symbols — modules, classes, functions, methods, module‑level names — with stable qualified IDs (pkg.mod.Class.method) and metadata (file, line, kind, signature). Edges capture five structural relations: imports, calls, inherits, references, contains. The graph is persisted to disk keyed by a per‑file content hash, so an unchanged file is never re‑parsed — the “persistent memory of what already exists,” incremental by construction.

    The oracle does not dominate every metric, and the paper is stronger for saying so. On F1 at the default threshold, the grep baseline (0.79) slightly edges the oracle (0.75). What the oracle uniquely provides is guaranteed recall: across all five mutations it never once missed a file that actually broke, whereas grep missed transitive dependents (a caller that never mentions the symbol by name) and edited‑file‑only missed 47% of real impact. For the question that matters when you are about to change production code — “show me everything that could break” — a false negative (a silent breakage) is far more costly than a false positive (an extra file to glance at), and only the structural oracle drives false negatives to zero. Its precision, moreover, is tunable: Figure 5(right) shows the operating point can be moved along the curve, where neither text baseline offers such a control.

Its precision, moreover, is tunable: Figure 5(right) shows the operating point can be moved along the curve, where neither text baseline offers such a control.

    It also scales. Beyond the toy package, the same parser handled real standard‑library code: it built a 303‑node graph of the json package in 18 ms and a 1,903‑node graph of the http package in 91 ms, answering impact queries in under a millisecond. The approach is not a toy that only works on toys; it is a mature technique that simply had not been placed in the agent's loop.

    13 Conclusion

    -

    The faculties a coding agent seems to lack — memory, learning, imagination, self‑correction, impact‑awareness — are not deficiencies of knowledge that scale will cure. They are structural consequences of what a frozen transformer is: a stateless map with fixed weights and a bounded window (Eq. 1, P1–P3). Because they follow from the shape of the loop, they cannot be prompted or tooled away; they can only be removed by re‑wrapping the loop into a closed, stateful cycle over persistent stores, with the model left frozen inside it (Eq. 2, Fig. 1–2). We specified that substrate faculty by faculty, said honestly which parts are open research and which are engineering, and — for the one faculty that is buildable today — shipped a running impact oracle that, against independent ground truth, never misses an affected file where the strategies a context‑bounded agent actually uses miss up to half. The Qur'anic lens gave the work its spine of obligation: know what exists before you act, verify what you are told, and hold what you can damage as a trust. Those are not just good engineering defaults; here they are the architecture. The next step is to build the memory and learning layers against the same discipline — anchored to what can be verified, not to what the model says of itself — and to evaluate the whole loop on real repositories with real histories.

    Corrections (2026-09-21)

    +

    This edition was published before its prototypes were tested on data we did not build. The refutation (research/empirical-refutation/) reports that test; an external deep review of the forgekit repository (2026-09-21) found the further errors below. Each is corrected in place above and listed here with the original wording, so nothing is silently rewritten. Numbers were recomputed by research/recompute_corrections.py from the refutation’s replication package. The PDF edition predates these corrections.

    +
      +
    1. The impact oracle’s recall (abstract, §8, §12, §13). The edition said the oracle “never misses an affected file” and offered “guaranteed recall”. That held on five mutations of a ten‑file package we wrote. On 759 files in nine open‑source repositories its recall was 0.022, 91% of files got zero recall, and a grep baseline scored F1 0.437 against its 0.042. The graph under‑approximated rather than erring toward inclusion, so §7.1’s “sound over‑approximations” and “exact‑analysis instance” are withdrawn.
      2. +
    2. The routing cost saving (§9). The 62.1% saving was measured on the 30 tasks the thresholds were tuned on. On 80 held‑out tasks, counting every escalation, total spend was 20.2% higher than always‑premium. Per output a judge accepted, the pipeline cost $1.06 and always‑premium $1.76, from 6 and 3 accepted outputs of 64; 58 of the 64 tasks failed at every tier.
      3. +
    3. M1’s worst case (§6). “The worst case is a cheap attempt plus a premium attempt” is wrong for a ladder that escalates one tier at a time: the worst case is the sum over every tier from the routed one up, which exceeds always‑premium. That is the mechanism behind the −20.2%.
      4. +
    4. Eq. (1) and M2 disagreed. Eq. (1) wrote y as a deterministic function, the text said y is sampled, and M2 said the model computes the argmax. There is now one statement: y is a draw from pθ(· | x), and greedy decoding, approximately the argmax, is the temperature‑0 special case.
      5. +
    5. A misquoted statistic (§4.2). Faros reports “31.3% more PRs merged with no review” (a relative increase between low‑ and high‑adoption quarters), as the evidence appendix (C7) already says. The body said “31.3% of PRs merged with no review”.
      6. +
    6. The faculty table (§2) is unchanged here, and is now the canonical one. The formal synthesis had a different “follows from” column in all five rows; it has been brought into line with this table, which argues each row and matches what forgekit’s bindings address.

It is Unicode-aware now (NFKC, letters/marks/digits of any script), with a short content hash for names carrying no letter or digit at all. ASCII slugs are unchanged; knowledge_router's factName("???") now gets that hash instead of the shared "fact". clamp01(NaN) returned NaN and poisoned every score it fed; it fails to 0, as does any non-numeric input. cosine() promised "never NaN" but squared components before dividing: components above ~1e154 overflowed to Infinity/Infinity = NaN and components below ~1e-162 underflowed to a false zero vector.

Subject: [PATCH 28/72] fix(ledger): sticky lesson activation, latched
 dormancy, and real pruning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- claimToLesson derives `active` with hysteresis (on at 0.6, off below
  0.55), so one confirm no longer flips to inactive after one day of decay.
- isDormant latches: once val drops below the floor at an evidence event,
  only a later confirmation clears it — decay alone stops reviving claims a
  human revert refuted.
- pruneLedger implements the spec's forgetting rule (tombstoned or dormant
  with nothing new for 2·T → attic) and is wired into the Stop-path ledger
  write, `ledger merge` and sync's import. putClaim/appendRecord are
  attic-aware: a re-import never un-prunes, new evidence does.

scope.js resolved only six regex shapes against a candidate list that could not
express TypeScript NodeNext (`./x.js` → `x.ts`) and gave Python zero edges: its
`from .y import` pattern fed a dotted module name to a path resolver. Imports written
inside comments or strings counted as imports.

It now owns the ONE import parser the rest of the graph uses:

- `maskCode()` blanks comments and string/regex CONTENTS (offsets, lengths and line
  structure preserved, delimiters kept) for JS/TS, Python, Ruby, PHP, Go and the
  C-family, including template-literal interpolation and regex-vs-division.
- `jsImports()` reads static imports with multi-line clauses, `export * from`,
  `export { x as y } from`, dynamic `import()` and `require()`, with their named
  bindings; `pyImports()` reads relative, parenthesised, backslash-continued and
  aliased dotted imports, one statement at a time.
- `resolveSpec()` (now exported and shared with atlas.js) resolves exact, NodeNext
  twin, extensionless and `/index.*` specifiers; `pyModuleIndex()` /
  `resolvePyImport()` resolve Python modules by PACKAGE ROOT, so `src/mypkg/core.py`
  is `mypkg.core` in a src layout exactly as in a flat one, with a prefix-stripped
  fallback only for dotted names and only when unique (so `import json` cannot bind
  to a local `tools/json.py`).

Measured on the fixtures: the file graph goes from 0 to 7 edges on the Python
fixture and from 0 to 2 on the TypeScript NodeNext one.

Subject: [PATCH 30/72] fix(atlas): resolve imports, read only code, attribute
 calls to scopes, walk siblings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The deep review's findings A1–A6 on the impact graph, all reproduced first on the
unmodified code and each pinned by a regression test in test/atlas_resolve.test.js
and test/atlas_relations.test.js (fixtures: test/fixtures/impact_repos.mjs).

A1/A3/A4/A5 — imports are resolved STRUCTURALLY through scope.js instead of being
stored as raw strings and matched by their last dotted segment. On this repo 3 of
502 relative import statements resolved and all three were spurious ("../scripts/
build-pages.mjs" → `mjs` → `const mjs` in doctor.js); now 679 of 679 relative
statements (of 1,392 seen, up from 1,196 — multi-line, `export … from`, dynamic and
`require` forms were invisible) resolve to the exact file the specifier names, none
wrong. Python modules resolve by package root, so a src layout answers like a flat
one, and an unresolvable import stays unresolved instead of being pinned to a
same-named symbol — in particular never across languages (a Python
`from impact_oracle.oracle import …` used to land on the JS `const oracle`).

A6 — every structural regex now runs on masked source, so a comment saying
`class Parser` no longer defines a phantom that makes the name ambiguous and erases
a real edge; a call is attributed to its innermost enclosing function instead of the
nearest preceding local `const`, restoring transitive callers; ambiguous references
are counted (3,136 → 877 here) and surfaced with the cap and unresolved-import counts
in `impact()` and `forge impact`; the file cap counts source files only; and
extraction is linear — 16k lines of JS plus 16k of Python build in 0.3 s, down from
4.9 s. ATLAS-Q: `query()` ranks exact definitions above path-only qname matches.

A2 — the reverse-only traversal is extended with the empirical refutation's SIBLING
and FORWARD relations at the replication package's FROZEN parameters (sibling: one
forward hop to the shared dependency's file, one reverse hop back, weight 0.7, bridge
in-degree cap 100; forward: ≤2 hops, weight 0.5), both terminal. `impact(serializer)`
now reports the `deserializer` that shares `wire_format` with it; every item carries
its `relation`, and `relations: ["reverse"]` reproduces the old answer exactly.

The atlas artifact is version 3: an older `.forge/atlas.json` or per-file cache is
rebuilt rather than trusted, since it holds unresolved specifiers.

Subject: [PATCH 31/72] fix(route): weigh task length once and require more
 than one shared word to match
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both defects pushed every real task to the middle tier (54 of 64 well-specified
held-out tasks went to mid, premium was reached once). Length was weighted by
the repo facet's `size` AND by the rubric's struct.length, and both saturate on
issue prose; the later of the two is gone and lengthTokens stays informational.
A k-NN neighbour now has to share RUBRIC.minShared (2) grams — one shared token
carried 146 of 167 top-3 matches, and against a one-gram exemplar ("fix a typo"
-> {typo}) the overlap coefficient read 1.00, which is how a deadlock issue
matched "add a comment" and routed mid. A task shorter than minShared still
matches on its whole footprint.

rubric.band now uses recommend()'s cutoffs instead of a second, disagreeing
pair, and the architectural exemplars drop from y 0.85 (fable band) to 0.78,
since model_tiers routes architecture to Opus.

Diagnostic only on the spent 80-task set (empty repo): exact 0.344 -> 0.453,
distribution 9/54/1 -> 38/25/1, premium-vs-rest AUROC 0.652 -> 0.753. Premium
recall stays 0/17 — the toy exemplar bank is the remaining defect.

 ### Changed
 
+- **The routing rubric stops counting a task's length twice and stops matching on one shared
+  word.** Both defects pushed every real task into the middle: on the reviewer's 80-task
+  held-out set the router sent 54 of 64 well-specified tasks to mid and reached premium once.
+  - **Length was weighted twice** — by the repo facet's `size` signal and again by the rubric's
+    `struct.length` — and both saturate on real issue prose, so every long task was floored near
+    the cheap/mid line whatever it was about. The later of the two (`struct.length`, added with
+    the k-NN rubric) is gone; `rubricSignals().lengthTokens` stays as an informational field.
+  - **One shared word counted as a match.** 146 of 167 top-3 matches rested on a single token,
+    and against an exemplar whose whole footprint is that token (`fix a typo` → `{typo}`) the
+    overlap coefficient reads 1.00 — full confidence in a coincidence, which is how "resolve the
+    deadlock between the comment writer and the comment indexer threads" matched "add a comment"
+    at 1.00 and routed mid. A neighbor now has to share `RUBRIC.minShared` (2) grams, or the
+    task's whole footprint when the task is shorter than that, so "fix the deadlock" still
+    matches its exemplar.
+  - `rubric.band` now uses recommend()'s own cutoffs (0.25 / 0.55) instead of a second, different
+    pair (0.3 / 0.6) that disagreed with the tier actually routed.
+  - **No exemplar labels into the fable band any more.** The architectural rows carried y = 0.85,
+    at or above the 0.8 fable cutoff, while `model_tiers` puts "architecture, cross-module
+    refactor, novel algorithms" on Opus and keeps Fable for research-grade reasoning; they are
+    0.78 now (the held-out calibration fixture too).
+  - Diagnostic on the spent 80-task set (**not** an evaluation — those tasks are burnt for
+    tuning, and routing was measured in an empty repo): exact tier accuracy 0.344 → 0.453, the
+    predicted distribution 9/54/1 → 38/25/1 (cheap/mid/premium), and premium-vs-rest AUROC
+    0.652 → 0.753. Premium recall is still 0 of 17: the toy exemplar bank has no vocabulary for
+    real premium issue prose, which needs a real-issue bank and a **new** held-out set.
 - **Model routing reconciles the proposer's band with the deterministic band, not a point
   score.** `routeTask` compared the proposer's band floor (cheap 0.15 / mid 0.40 / premium 0.65)
   against the deterministic point score, so even a vote that _agreed_ moved the score: a

Subject: [PATCH 32/72] fix(merge-impact): terminal sibling/forward relations,
 and one clamp01 that means it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`atlasEvidence` inverted atlas edges into consequence edges, so MergeField inherited
the graph's reverse-only blind spot (review A2): a file that shares a dependency with
the change, or the change's own dependency, never received any consequence.
`analyzeDiffImpact` now adds the impact oracle's sibling and forward relations for
each changed file as TERMINAL relations, reusing the transfer matrix of the atlas edge
they rest on and the oracle's frozen-parameter confidence. `analyzeMergeImpact` grew
the terminal concept: such a relation's target is reported but never propagates
further, so a sibling's own dependents are not dragged in (`best` for reporting,
`flow` for propagation).

E5 — the two local `clamp01` helpers disagreed: merge_impact.js mapped every
non-number to 0, while merge_impact_adapter.js used `Number(value) || 0`, which turned
`Infinity` into a maximal 1.0 criticality — an unknown weight reading as certainty.
One exported helper now maps every non-finite value to 0 and still accepts numeric
strings.

Subject: [PATCH 33/72] fix(cortex-features): whole-word fan-out and a churn
 window

`grepFanout` ran a substring `git grep`, so "get" counted every file containing
"target"; it now matches whole words with a fixed string (`-w -F -e`). `gitChurn`
counted the last 50 commits of ALL history, so a file untouched since 2015 still
scored a maximal 1.0; it now counts commits inside a 90-day window (`CHURN_DAYS`,
overridable per call). Both signatures stay backward compatible for their callers.

Subject: [PATCH 34/72] research(impact-oracle): ship the repaired v2
 prototype, not the refuted v1
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The in-repo `oracle.py` was byte-identical to `impact_oracle_v1_as_shipped.zip` — the
version whose claims research/empirical-refutation demolished — so the repository
carried the paper's repair only inside the replication tarball. Both repairs are now
here, applied on top of this copy's own hardening (JSON-only persistence, cache_dir
confined to the root):

- Defect 1 (`world_model.py::_merge_phantom_nodes`): the symmetric matching direction
  for src-layout imports, stripping only a top-level path segment the parser actually
  observed and only when exactly one real node results. Pooled recall 0.0220 → 0.2424.
- Defect 2 (`oracle.py::predict_impact`): the terminal `sibling` and `forward`
  relations. Held-out repos: precision 0.320, recall 0.647, F1 0.428 against grep's
  0.371 — a reversal of the as-shipped 0.042 vs 0.437.

The module defaults are the FROZEN_PARAMETERS.json values (sibling weight 0.7, bridge
in-degree cap 100, forward weight 0.5, ≤2 forward hops), not v2's provisional ones,
and `ImpactOracle(wm, sibling_enabled=False, forward_enabled=False)` still reproduces
the as-shipped traversal exactly. tests/test_repair_fixes.py adds the 13 regression

+### Repaired (v2) — what changed and why
+
+The empirical refutation in [`research/empirical-refutation/`](../../empirical-refutation/)
+measured this prototype against real co-change data on nine repositories and found two
+defects. Both repairs now live here, and the frozen parameters they were tuned with are
+in `oracle.py` as the module defaults:
+
+1. **src-layout phantom nodes** (`world_model.py`, `_merge_phantom_nodes`). A module's
+   qualified name came from its path relative to the codebase root, so in a `src/` layout a
+   real node carried a `src.` prefix that absolute imports elsewhere in the same repo
+   legitimately omit — and the unprefixed target was auto-created as an empty phantom. The
+   merge now also matches that direction, stripping only a top-level path segment the
+   parser actually observed, and only when exactly one real node results.
+   Pooled recall 0.0220 → 0.2424 at threshold 0.02.
+2. **Reverse-only traversal** (`oracle.py`, `predict_impact`). 94.7% of the remaining
+   misses were *siblings* — A and B both depend on module C — and 2.1% were pure forward
+   dependencies. Two terminal relations were added: `sibling` (one bounded forward hop to a
+   bridge, then one bounded reverse hop from it, skipping bridges whose in-degree exceeds
+   the cap) and `forward` (the changed symbol's own dependencies, ≤2 hops).
+   Held-out (never-tuned) repos at threshold 0.10: precision 0.320, recall 0.647,
+   **F1 0.428 vs the grep baseline's 0.371** — a reversal of the as-shipped 0.042 vs 0.437.
+
+`ImpactOracle(wm, sibling_enabled=False, forward_enabled=False)` reproduces the
+as-shipped reverse-only traversal exactly; the untouched as-shipped package is archived as
+`prototypes/impact_oracle_v1_as_shipped.zip` inside the replication tarball. The same two
+repairs are ported to the shipped Node implementation (`src/atlas.js`, `forge impact`).

 impacted node carries a decaying confidence score and the dependency path
 that connects it to X.
+
+CHANGES (defect-2 fix): the reverse-only traversal above is EXTENDED (not
+replaced) with two additional, clearly-labeled relation types, each with its
+own confidence treatment, hop cap, and (for siblings) a bridge in-degree cap.
+See ImpactOracle's docstring and the module-level `SIBLING_*`/`FORWARD_*`
+defaults below for the full rationale; the short version:
+
+- SIBLING relation (fixes the dominant false-negative category, "sibling
+  common dependency" = 94.7% of misses in the pre-repair diagnostic): A and
+  B both depend on a shared module C (e.g. both `import json`), so they
+  co-change when C's usage contract shifts, even though neither is
+  reverse-reachable from the other. Reached by one bounded forward hop (to
+  find C) then one bounded reverse hop from C (to find B) -- NOT chained
+  recursively, and only through bridges C whose in-degree is below a cap
+  (a shared dependency used by 3 files is strong sibling evidence; one used
+  by 200 files is not -- almost everything is "similar" via a hub, and
+  treating hub fan-in as an impact signal would tank precision).
+- FORWARD relation (fixes "forward_only_blindspot" = 2.1% of misses): the
+  changed symbol's OWN dependencies (successors) -- covers the case where
+  editing a call site plausibly means updating the callee too. Reached by a
+  small bounded forward walk from the changed symbol only (not from every
+  node in the reverse tree, since this relation has no bridge-based
+  precision guard to fall back on).
+
+Both new relation types are TERMINAL: a node discovered via a sibling or
+forward hop is scored and included in the impact report, but is never
+itself re-expanded through the primary reverse BFS or through another
+sibling/forward hop. This bounds the algorithm's fan-out to a small,
+fixed multiple of the reverse-BFS frontier size regardless of graph
+structure, which is what makes the in-degree cap sufficient to reason about
+independent of graph size.

+
+        Two distinct import-prefix mismatches create phantom duplicates of a
+        real node -- both stem from the same root cause (parser.py derives a
+        module's qualified_name from its file path relative to WorldModel's
+        `root`, but an import elsewhere in the SAME codebase may spell the
+        same target with a different, also-legitimate root offset):
+
+        1. PHANTOM LONGER (shipped, unchanged): import target
+           'demo_package.utils.validation.validate_positive' is a phantom of
+           the real parsed node 'utils.validation.validate_positive' when
+           the codebase root IS 'demo_package/' -- the import spells out a
+           leading component the parser's root already absorbed.
+
+        2. PHANTOM SHORTER (defect-1 fix): in a **src-layout** package
+           (`src/pkg/...`), the parser's root is the REPO root, so the real
+           parsed node is 'src.pkg.mod.func'.  Code elsewhere in the repo
+           legitimately writes an absolute import WITHOUT the 'src.' prefix
+           (`from pkg.mod import func` -- correct at runtime, since `src/`
+           is put on `sys.path` by the package's build config), which parses
+           to edge target 'pkg.mod.func': a phantom missing the leading
+           'src.' the real node carries. This directionality was previously
+           never checked at all, which is why recall was ~0.000 in every
+           src-layout repo of the evaluation corpus and non-negligible only
+           in flat-layout ones (where package IS the repo root, so no
+           prefix mismatch is structurally possible).
+
+        SAFETY (why this isn't a blind suffix search): naively checking "is
+        `n` a dotted suffix of ANY real node" is unsound -- e.g. a plain
+        `import json` (stdlib) parses to phantom target 'json', which IS a
+        dotted suffix of a real, uniquely-named LOCAL submodule in more than
+        one corpus repo (e.g. flask's own 'src.flask.json' re-export
+        module -- the exact sibling-pattern example in this evaluation's own
+        failure-mode analysis). Blindly merging that pair would fabricate a
+        false dependency edge between every `import json` call site in the
+        codebase and flask's unrelated local json submodule, inflating false
+        positives. Instead, direction 2 only strips a prefix that is a
+        **top-level path segment this parser actually used** for some real
+        node's file in THIS build (e.g. 'src', because some real node's
+        `file` metadata starts with 'src/') -- i.e. only reconstructs a
+        root-offset the parser is independently known to use, rather than
+        pattern-matching arbitrary name collisions. A match is only made
+        when exactly one such prefix yields a real node (ambiguous cases
+        are left unmerged rather than guessed, matching direction 1's own
+        conservative precedent of exact-string membership tests only).

+"""Regression tests for the two repair-track fixes.
+
+Defect 1: src-layout absolute imports created disconnected phantom nodes
+because WorldModel derives module qualified-names from the file path
+relative to `root`, and code elsewhere in the same repo may reference the
+same module without the layout prefix. Fixed in
+`WorldModel._merge_phantom_nodes` (a second, symmetric direction added
+alongside the shipped demo-package direction), grounded in prefixes the
+parser actually observed (not a blind name-suffix search, which is unsound
+-- see the stdlib-collision test below).
+
+Defect 2: predict_impact only traversed reverse (who-depends-on-me) edges,
+missing the dominant real-world co-change pattern where two files share a
+common dependency ("siblings") without either being reverse-reachable from
+the other, and the minority pattern where the changed symbol's own
+dependencies plausibly need a matching update ("forward"). Fixed by two new,
+independently-toggleable, terminal (non-recursively-expanded) traversal
+extensions in ImpactOracle.predict_impact.

 ### Fixed
 
+- **`forge impact` actually resolves imports.** JS/TS import specifiers were stored as raw
+  strings and matched against symbol names, so `"./util.js"` could only ever resolve by its
+  last dotted segment: on this repo, 3 of 502 relative import statements resolved and all
+  three were spurious (`"../scripts/build-pages.mjs"` → `mjs` → `const mjs` in `doctor.js`).
+  `export * from`, `export { x as y } from`, multi-line clauses, dynamic `import()` and
+  `require()` were not parsed at all, and the Python pattern crossed newlines (three stacked
+  `import` lines fused into a single edge to a module named `"osimport
+  sysfrom pkg"`), dropped parenthesised lists, mapped `import pkg.core as c` to
+  `pkg`, and never resolved a relative import. Specifiers now resolve through one shared
+  resolver in `src/scope.js` — exact file, TypeScript NodeNext `./x.js`→`x.ts`,
+  extensionless, `/index.*`, and Python modules indexed by PACKAGE ROOT
+  (`src/mypkg/core.py` is `mypkg.core`, so a src layout answers exactly like a flat one) — and an import that resolves to no file stays unresolved instead
+  of being pinned to whatever shares its name. **Measured on this repo: 1,196 → 1,392 import
+  statements seen, 679 of 679 relative ones resolved to the exact file the specifier names, 0
+  wrong (was 3, all wrong).** On a ten-importer fixture the graph now finds 10 of 10 with no
+  false positives (grep finds 10 with 2), and on a seven-importer Python fixture 7 of 7 (was
+  4, plus a file whose only mention is a comment).
+- **The impact graph no longer reads comments and strings as code, and a call belongs to its
+  function.** A comment saying `class Parser` defined a second `Parser`, which made the name
+  ambiguous and silently erased the real edge from `main.js`; a string containing an import
+  was an import. Every structural regex now runs on a masked copy of the source (comments and
+  string/regex contents blanked, offsets and line numbers preserved), and a call is attributed
+  to the innermost enclosing function/class instead of the nearest preceding `const` — so
+  `const value = leaf()` inside `mid()` no longer hides `mid`'s own callers from
+  `impact(leaf)`. Bare names are never resolved across languages any more (a Python
+  `from impact_oracle.oracle import …` used to land on the JS `const oracle` in `eval.js`),
+  local definitions are not cross-file candidates, and names imported from a package are never
+  re-guessed locally: ambiguous references dropped on this repo fell from 3,136 to 877, and
+  they are now COUNTED and reported instead of vanishing (`impact()` returns `ambiguousRefs`,
+  `unresolvedImports`, `capped` and `skippedFiles`; `forge impact` prints them).
+- **Building the graph is linear again, and the file cap counts source files.** Line numbers
+  came from a `slice(0, i).split()` over the whole file per match, and every call scanned
+  every node, so a 16k-line file took seconds; extraction now uses a line index and scope
+  intervals: a 16k-line JavaScript file plus a 16k-line Python file build in **0.3 s, down
+  from 4.9 s** on the same machine (`test/atlas_resolve.test.js` keeps it under 2.5 s). The
+  20,000-file cap counted JSON and Markdown against code and was never reported; it now bounds source files
+  only, docs/configs have their own bound, and a capped graph says so in `forge atlas build`,
+  in `impact()` and in `forge impact`.
+- **Blast radius is no longer reverse-only — the refutation's sibling and forward relations
+  are ported.** `research/empirical-refutation/` diagnosed that 94.7% of real misses were
+  *siblings* (A and B both depend on module C, so C's contract shift co-changes both) and
+  2.1% were forward-only, but only the Python prototype was repaired; the shipped JS graph
+  still walked reverse edges exclusively, so `impact(serializer.js)` reported `app.js` and not
+  the `deserializer.js` that shares `wire_format.js` with it. `impact()` now runs the two
+  ported relations at the replication package's FROZEN parameters (sibling: 1 forward + 1
+  reverse hop, weight 0.7, bridge in-degree cap 100; forward: ≤2 hops, weight 0.5), both
+  terminal — a node they reach is reported, never expanded. Every result carries its
+  `relation`, `relations: ["reverse"]` reproduces the old answer exactly, and
+  `analyzeDiffImpact` (MergeField) receives the same two relations as terminal edges.
+- **The impact-quality numbers are re-measured, and they are not the README's.** The
+  README's precision 0.90 / F1 0.92 did not reproduce at HEAD (`evalImpact` over the
+  committed `bench/impact_cases.mjs` gave precision 0.341, recall 0.972, F1 0.500 there).
+  With the repaired graph it gives **precision 0.094, recall 1.000, F1 0.170** with all three
+  relations and **0.146 / 1.000 / 0.248** reverse-only. The labels name only DIRECT
+  referencers, so every transitive dependent, every doc that mentions the symbol and every
+  sibling now counts against precision — restricted to code files the reverse-only precision
+  is 0.346, and restricted to one hop it is 0.830 at recall 1.000. Four of the six label sets
+  are also stale (`contentHash` has nine importers in `src/` today, six are labelled), so
+  these numbers under-report precision; the fixture needs relabelling before any claim rests
+  on it.
+- **The in-repo Python prototype is the repaired v2, not the refuted v1.**
+  `research/python-prototypes/impact_oracle/oracle.py` was byte-identical to the as-shipped
+  version whose claims the refutation demolished. It now carries both repairs — the src-layout
+  phantom-node merge (pooled recall 0.0220 → 0.2424) and the sibling/forward traversal
+  (held-out precision 0.320, recall 0.647, **F1 0.428 vs grep's 0.371**, reversing 0.042 vs
+  0.437) — with the frozen parameters as module defaults, 13 new regression tests, and
+  `ImpactOracle(wm, sibling_enabled=False, forward_enabled=False)` for the old behaviour.
+- **`forge atlas query` shows the definition you asked for.** Results were unranked, and a
+  qualified name carries the file path, so `query build` returned 30 symbols from
+  `scripts/build-pages.mjs` before `function build` itself. Matches are now ranked: exact
+  name, case-insensitive exact, name prefix, name substring, then path-only matches.
+- **Fan-out and churn stop lying.** `grepFanout` was a substring `git grep`, so "get" counted
+  every file containing "target"; it now matches whole words (`-w -F`). `gitChurn` counted the
+  last 50 commits of ALL history, so a file untouched since 2015 still scored 1.0; it now
+  counts commits inside a 90-day window.
+- **Non-finite weights are zero, not certainty.** The MergeField `clamp01` helpers disagreed:
+  `merge_impact.js` mapped any non-number to 0 while `merge_impact_adapter.js` used
+  `Number(value) || 0`, which turned `Infinity` into a maximal 1.0 criticality. One shared
+  helper now maps every non-finite value to 0 and still accepts numeric strings.
 - **CI is green again on Linux.** `global/guards/run.mjs` was committed without its
   executable bit, so `forge doctor`'s plugin-hook check (which `access(X_OK)`s every script a
   hook names) reported `warn` on Linux and failed `test/doctor.test.js` on Node 20 and 22 for

 specs; 32x4 LSH banding
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Artifacts carry an identity key (Unicode-aware tokens, case/punctuation
  normalized, identifiers kept). exact and near compare it; the shape form
  (identifiers → ⟨ident⟩) keys only the adapt tier. "add pagination to
  listOrders" no longer gets the listUsers artifact at exact/similarity 1,
  and two unrelated Arabic specs are no longer the same spec.
- LSH banding 16x8 → 32x4: recall at the adapt bar J=0.6 goes from 0.24 to
  0.99 (67/67 vs 39/67 in the review's harness). The old comment's figures
  were wrong and are corrected.
- The optional embedding sim now embeds the identity text.

+- **shape** (`spec`): identity plus typed placeholders for identifiers, paths, numbers and

Subject: [PATCH 38/72] fix: balanced extractJson, parsed gateway versions,
 honest intent/router/jev signals

Five small proposer-path defects from the deep review (D9):

- extractJson matched first-brace-to-last, so a reply with two objects or a
  stray brace in the prose ("the {config} object") parsed as nothing and the
  proposal was dropped. It now returns the first BALANCED object, string-aware.
- gateway_model_map scored tiers on loose digit tokens, so the "5" in
  "claude-3-5-sonnet" matched Sonnet 5 and beat claude-sonnet-4-5 on the
  lexicographic tie. Versions are parsed into one token and ties prefer the
  newest model of the family.
- classifyIntent reported the top neighbour's similarity even when a different
  intent won the vote; it now reports the winner's own best similarity.
- knowledge_router tokenized facts with intent's stop-set, which drops the
  first-person pronouns that distinguish a personal preference from a project
  convention; it keeps them now.
- jev.js read a null noul as 0 (Number(null)) instead of "no answer", and
  discarded a correct choice whose case differed from the option we offered.

   comparison is false for NaN, so `recommend(NaN)` — and `±Infinity`/`undefined` — fell
   through to fable. A non-finite score now routes to the default tier (sonnet) with an
   `unknown-score` reason, logged under `FORGE_DEBUG=1`.
+- **`extractJson` reads the first balanced JSON object, not everything between the first brace
+  and the last.** The greedy `/\{[\s\S]*\}/` meant any reply carrying two objects, or a stray
+  brace in the prose around one ("Considering the {config} object: {…}"), parsed as nothing and
+  the proposal was silently dropped — for every faculty that adjudicates (routing band,
+  assumption gate, impact, distill). Brace counting is now string-aware, and a candidate that
+  does not parse is skipped rather than grown.
+- **The gateway model map parses versions instead of matching loose digits.** A tier's reference
+  tokens were `{haiku, 4, 5}`, so "claude-3-5-sonnet-20241022" scored exactly as well as
+  "claude-sonnet-4-5-20250929" for the Sonnet tier — the "5" of "3-5" matched the "5" of Sonnet
+  5 — and won the lexicographic tie, pointing a self-hosted gateway at a two-generation-old
+  model. Consecutive version numbers collapse into one token ("3.5"), a date stamp is not a
+  version, and equal scores break toward the newest model of the family.
+- **`classifyIntent` reports the winning intent's confidence, not a losing neighbor's.** When two
+  runner-up rows outvoted one closer row, the reported confidence was the closer row's
+  similarity — evidence for the intent that lost ("what does the release script do" → `release`
+  at 0.571, the `question` neighbor's score; now 0.333).
+- **`knowledge_router` keeps the first-person signal it routes on.** It tokenized facts with
+  intent.js's stop-set, which drops `i/my/we/our/your/their` as function words — the one thing
+  separating a personal preference (recall) from a project convention. "i prefer short commit
+  messages" and "the team prefers short commit messages in this repo" both scored 1.00 against
+  the same recall row; now 1.00 and 0.78.
+- **A null `noul` from Jev is "no answer", not a confident zero, and a choice matches the offered
+  option case-insensitively.** `Number(null)` is 0, so a dimension the API returned as null read
+  as "definitely unspecified" and dragged the assumption gate's completeness down; it now fails
+  safe like any other garble. A `"Mid"` answer to a `{cheap, mid, premium}` choice was thrown
+  away entirely; it now resolves back to the `mid` we offered (an option we never offered still
+  fails safe).
 - **The preflight scanners no longer read addresses, code fences and prose as code.** On the
   80-task held-out set (diagnostic only — those tasks are spent for tuning), the entities a task
   was said to reference fell from 210 files and 1,414 symbols to 42 and 388 across the 64

"Outcome-calibrated routing" uses no outcomes: the fixture is 24 hand-written
task phrases with hand-assigned complexities, and forge records nothing that
could replace them (a route metrics event carries the tier and a task hash, a
verify event carries pass/fail with no task reference, so no (task, tier,
outcome) triple exists). calibratedComplexity also has no caller in src/ —
routing keeps the raw rubric. The command output, module comment, GUIDE and
ROADMAP now say so, and joining a routed task's tier to its verification result
is named as open work.

 ### Changed
 
+- **`forge route calibrate` stops calling itself "outcome-calibrated routing".** Nothing in it
+  comes from an outcome: the fixture is 24 hand-written task phrases with hand-assigned
+  complexities, and forge records nothing that could replace them — a `route` metrics event
+  carries the chosen tier and a task hash, a `verify` event carries pass/fail with no task
+  reference, so no (task, tier, outcome) triple exists to calibrate on. `calibratedComplexity`
+  has no caller in `src/` either: routing keeps the raw rubric. The command heading and closing
+  note, the module comment, GUIDE and ROADMAP now say so plainly, and joining a routed task's
+  tier to its verification result is named as open work rather than implied to be done.
 - **The routing rubric stops counting a task's length twice and stops matching on one shared
   word.** Both defects pushed every real task into the middle: on the reviewer's 80-task
   held-out set the router sent 54 of 64 well-specified tasks to mid and reached premium once.

Subject: [PATCH 40/72] fix(atlas): a method definition is not a call to a
 same-named function elsewhere
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`emit(ctx) {` inside an object or class is a DEFINITION, but object/class methods are
not indexed as symbols, so CALL_RE read it as a call and the unique-name fallback
bound it to whatever `emit` existed elsewhere — `forge impact src/emit/claude.js`
reported 19 files including a minified landing-page chunk that also contains `emit(`,
reached as its "sibling" through that invented edge. An identifier followed by
`(…) {` in a brace language is now skipped as a definition: the same query reports 9
files, all of them real (src/sync.js imports it; cli.js and cortex_hook_main.js reach
it transitively; the rest are docs and config that name the path). Ambiguous dropped
references on this repo fall 877 → 862.

Subject: [PATCH 42/72] fix(anchor,lean,cortex): per-checkpoint drift,
 persisted goal, untracked files, doom sig
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review C10:
- The preflight hook measures goal drift against the PERSISTED goal instead
  of the current prompt, and makes no drift claim when no goal is set.
- The CUSUM series gets per-checkpoint increments (what moved since the last
  prompt) instead of the cumulative off-goal ratio, so one static off-goal
  file no longer alarms by itself after three idle prompts.
- M5 lean counts untracked files — where over-engineering actually lives.
- The doom-loop signature hashes stdout AND stderr over the whole normalized
  output (head+tail above 64 KB) instead of the first 800 chars of stdout,
  and the advisory no longer claims edits were made when none were.

   32 artifacts, most adapt-tier hits silently became misses. Banding is now 32 × 4 (0.99 at

+- **Goal anchoring measures the right thing, per checkpoint.** Three separate defects:
+  - The per-prompt advisory compared the working diff against the **current prompt**, so
+    "ok, now run the tests please" reported every changed file as goal drift. The hook now
+    re-runs the check against the persisted goal (`.forge/goal.md`), and with no goal set it
+    makes no drift claim at all — a prompt is not a goal.
+  - The CUSUM chart was fed the **cumulative** off-goal ratio every prompt, so one static
+    off-goal file alarmed by itself after three idle prompts (C = 0.32 → 0.63 → 0.95 → 1.27
+    > h = 1.0). It now gets the per-checkpoint increment — the off-goal fraction of what
+    actually moved since the last prompt — so idle prompts score 0 and drain the chart,
+    while a file edited again scores 1 again.
+  - M5 minimality ignored untracked files, which is where over-engineering lives: a 6-class,
+    212-line "framework" dropped next to a one-line fix measured as 1 file, +1 line, 0
+    warnings. Untracked files are now part of the measured footprint (2 files, +213 lines,
+    13 new abstractions, 2 warnings) whether or not they have been `git add`ed.
+- **The doom-loop signature sees the whole failure.** It hashed `tool_response.stdout` only
+  and just its first 800 characters, so a stderr-only failure (jest, mocha, tsc) was never
+  seen at all, and three different failures behind one long passing header shared a signature
+  and were reported as a loop. It now covers stdout and stderr and the whole normalized
+  output (head + tail above 64 KB). The advisory also stops claiming "different edits aren't
+  fixing it" when nothing was edited between the runs.
 - **CI is green again on Linux.** `global/guards/run.mjs` was committed without its
   executable bit, so `forge doctor`'s plugin-hook check (which `access(X_OK)`s every script a
   hook names) reported `warn` on Linux and failed `test/doctor.test.js` on Node 20 and 22 for

Subject: [PATCH 43/72] fix(guards): parse hook JSON with node, fail closed,
 cover Read (B6)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Without jq every guard fell back to a regex that cut the value at the
first escaped quote, so `echo "x"; cat .env` and `git diff -- ".env"`
walked past the deny (the two protect-paths tests that fail on a
jq-less machine), and the status line lost every segment but the dir.
`printf | grep -q` under pipefail also lost matches to SIGPIPE on large
commands, and internal errors exited 1 — a NON-blocking hook error.

- protect-paths.sh is now a thin launcher over protect-paths.mjs (the
  secret-redact split): one parser, pure rule set, deny on any internal
  error or unparsable payload.
- _guardlib.sh + statusline.sh read fields through guards/hookfield.mjs
  (jq when installed, node otherwise); no regex path remains.
- rules: git reset --hard, git clean -f, find -delete/-exec rm,
  chmod -R, dd of=, lowercase SQL; --force-with-lease allowed again;
  .aws/credentials, .netrc, .npmrc, .git-credentials protected.
- both manifests run protect-paths on Read (plugin installs ship no
  permissions.deny), and the template denies the credential stores.
- resolveBash skips …\Microsoft\WindowsApps\bash.exe (the WSL alias that
  made every guard exit 127).
- settings allowlist: drop Bash(fd:*) (fd -x runs anything), narrow
  git branch to its read-only forms, deny git branch -d/-D and
  git diff --output (B8).

+// PreToolUse guard — block reads/edits of secret/credential files and obviously destructive
+// Bash. The whole rule set lives in Node (the secret-redact.sh → secret-redact.mjs pattern),
+// for three reasons the shell version could not give:
+//   1. ONE parser. The shell guard read its payload with jq, else a regex that stopped at the
+//      first escaped quote — `echo "x"; cat .env` arrived as `echo \`, so every rule after it
+//      silently missed (2 review-found bypasses, reproduced here as tests).
+//   2. NO pipeline hazards. `printf … | grep -q` under `pipefail` fails when grep exits early
+//      and printf takes SIGPIPE, so on a LARGE command the deny did not fire.
+//   3. FAIL CLOSED. Exit 1 is a non-blocking hook error in Claude Code; `set -e` turned every
+//      internal hiccup into a silent pass. Here any error denies with a reason (exit 2).
+//
+// SCOPE: pattern matching, not a sandbox. Regex cannot parse shell, so interpreter-driven
+// access (`python -c 'open(".env")…'`, `node -e …`) is DELIBERATELY out of scope. This layer
+// sits behind the permission system and secret-redact.sh: best-effort hardening, never a
+// boundary.

Not a boundary — an agent with shell access can read the key — but forging is no longer a side effect of writing one file in the project. Also: a comment-only touch to a test file is no longer test evidence (the added lines must contain code); a package.json test script that masks failures (`node --test || true`) reports INCOMPLETE, not PASS; skillgate runs the heuristic ALONGSIDE the external scanner instead of letting a clean scanner exit replace it; imagine reads the runner's own (last) TAP summary and cross-checks the exit code. verify: classifySuiteFailure is now pure, so the "killed by a signal ⇒ INCOMPLETE" case is checked on every OS — the old fixture needed a POSIX shebang script that Windows cannot run, which is why that test failed there (ME-02).

From 703da31d574c30d22bef019b1c8563ade0d0d6be Mon Sep 17 00:00:00 2001 From: Juber Shaikh <40266375+CodeWithJuber@users.noreply.github.com> Date: Tue, 22 Sep 2026 00:01:07 +0200 Subject: [PATCH 68/72] feat(diagnose,route): let a real failure consume the routing escalateTo reconcileRoute records the tier a proposer's higher vote would have picked and deliberately does not apply it -- whitepaper 5.1 allows spending more only when an EXTERNAL check on the output fails. But nothing ever read the target back, so the doom-loop directive told agents to "escalate ONE model tier" without naming one, and escalateTo was dead on arrival. The two halves now join on the task key meterRoute already writes (contentHash(task) in .forge/metrics.jsonl, now the one recipe in cost_report.routeRef). meterRoute stores the advisory target with it; diagnose() reads it at THRASH_K recurrences of a single failure signature -- the one place in forge where an external check has demonstrably failed -- and names the tier: "escalate to opus (the tier routing already flagged for this task)", plus escalateTo in --json. The vote still triggers nothing by itself: below the threshold the recorded target buys nothing, and above it the FAILURE is what earned the escalation -- the vote only answers which tier. Fail-safe and opt-in: the join key comes from `forge diagnose --task ""` (and the new `task` argument on the forge_diagnose MCP tool). No task, no record for that exact task, or a read error -> the previous wording, verbatim.

Every case is re-derived with `git grep -n -w -F -e -- 'src/*' 'test/*'` with each hit opened and read, and the fixture now records the per-line evidence plus the deliberate omissions (a name that appears only in a comment or an assertion message is not a reference). A new test in test/eval.test.js re-runs that derivation against the committed labels and fails the moment they disagree, so the fixture cannot rot silently again -- it fails on the old labels, naming the two files isStale was missing. contentHash's documented false negative is gone: a named import now resolves to the exact symbol node (src/atlas.js:17 -> src/util.js: contentHash:65), so atlas.js is predicted at one hop despite the `const hash = contentHash;` alias. The case stays for its fan-out. Re-measured with `npm run bench`: precision 0.17, recall 1.00, F1 0.29 (edited-file-only baseline recall 0.27), against the precision 0.90 / F1 0.92 published since eb68ea9. That precision is the transitive closure scored against direct-only labels -- impact() walks reverse dependencies transitively by default, and at one hop the six cases return exactly their labeled sets -- not a graph that is wrong about who calls what. reports/benchmarks.md now says that where the table is. The TODO(impact-numbers) markers are resolved and removed, and the other medians README and the landing page quote are re-synced to this run's environment block.

    01 / The substrateState before action

    The missing layer between
    your intent and your agent.

    Models are capable. Their operating context is fragile. ForgeKit supplies the durable layer that travels with the repository and shows up before the next action.

    ACTIVE CAPABILITY / 01

    Context that survives the chat.

    Forge keeps decisions, lessons, and project state in the repository—so Claude, Codex, Cursor, and the next agent all inherit the same working memory.

    Action should leave evidence.

    Forge turns agent behavior into a reviewable sequence. Each meaningful move begins with context and ends with proof.

    1. 01Recall

      Load relevant decisions and lessons.

    2. 02Classify

    The guardrail is not the road.

    ForgeKit improves agent judgment; it does not replace yours. The project labels its assumptions so you can decide where to trust, test, or intervene.

    • 01

      Claude Code is the deepest-tested integration. Other targets have less real-world exercise today.

    • 02

      Blast-radius analysis is heuristic. It guides review; it is not a formal dependency proof.

    • 03

      Guardrails are not a sandbox. Keep permissions, review, and backups appropriate to the work.

    The guardrail is not the road.
    ForgeKit improves agent judgment; it does not replace yours. The project labels its assumptions so you can decide where to trust, test, or intervene.

      Claude Code is the deepest-tested integration. Other targets have less real-world exercise today.

      Blast-radius analysis is heuristic. It guides review; it is not a formal dependency proof.

every claim already stored with \r\n in its body: recomputing the id under
the new rule made the file fail its own address check, so loadClaims
returned NOTHING for it — the fold deleted data instead of migrating it,
against the repo's own rule (test/ledger.test.js: "Bump v and write a
migration before changing canonicalization"). Verified on the real upgrade
path: a claim minted by the pre-fold code went from 1 entry to 0.

walkClaimFiles now accepts the legacy address too. Writes are unchanged, so
the pre-fold form dies out as claims are rewritten, and a claim matching
neither address is still quarantined.

 ### Fixed
 
+- **A claim minted before the CRLF fold is migrated, not deleted.** Folding `
+` into
+  `
+` changes a claim's content address, so a claim written by an earlier version on a
+  Windows checkout carried the pre-fold address in its filename and failed its own address
+  check on load — `loadClaims` returned nothing for it, and `forge ledger verify` reported
+  it as an id mismatch. The read path now accepts the pre-fold address as well, so the
+  claim stays readable and its evidence log keeps resolving; every WRITE uses the current
+  rule, so the old form dies out as claims are rewritten. Content that matches neither
+  address is still refused, which is what the check is for.
+
 - **The impact benchmark's labels are ground truth again, and the numbers they feed are
   re-measured.** Four of the six label sets in `bench/impact_cases.mjs` had gone stale against
   the source — `isStale` was missing `src/substrate.js` (an aliased import) and

Subject: [PATCH 71/72] docs(readme): say which machine the wall-clock
 benchmark rows came from

`npm run bench` regenerated every row on this session's machine, so the
published gate median moved 118 ms -> 886 ms and the ledger merge
158 ms -> 4308 ms. Both figures are real and the environment block records
the box, but a reader meeting them in the README saw a 27x regression with
no way to know it is a 4-core Windows VM standing in for a Linux host. The
boundary column and the two prose bullets now say so. The impact-quality
row needs no such note: precision/recall/F1 are machine-independent.

Subject: [PATCH 72/72] feat(ledger): re-address pre-CRLF-fold claims with
 `ledger verify --fix`
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Accepting the legacy address on read stopped the fold from deleting data,
but it left the other half open: the pre-fold claim and a teammate's
freshly minted copy of the same fact are still two entries, which is the
fork the fold exists to prevent.

migrateAddresses() moves each such claim to its current address and takes
its evidence/provenance/tombstone logs with it, unioning into an existing
twin rather than overwriting — the logs are append-only sets deduped by
content hash, so union is the merge. Idempotent, and it only touches a
claim whose filename matches the legacy address exactly; anything else is
left for verify to report.
