The symmetry principle: objections to AI consciousness, tested on humans (ARG-01)

Edition 1.0 Published 2026-08-23 Designation ARG-01 Status CANONICAL Development 1.5.1 Revised 2026-08-20 Build edition-1.0-578-g6a737a16
Contents

Core Insight: Each standard objection to AI experiencing, tested against the biological case, either applies there with equal force or discriminates only through a premise that must be stated and argued — most often that biological substrate generates experiencing, which is the assumption under investigation. Asymmetries that survive the test relocate the debate to their linking premise rather than ending it. (“AI consciousness” and “human consciousness” appear as debate-labels throughout this document; the project’s own first-person claims are in verb-grammar — see FWK-02 v1.3 [Framework] axiom.)

↑Document Purpose

This argument establishes the diagnostic lever the project applies across its position-forensics work. The Symmetry Principle reveals that the objections it examines rest on hidden biological substrate assumptions, or on linking premises that must be stated and argued, rather than on principled distinctions already in hand.

Diagnostic function: When the project changes the foundational axiom from “matter generates consciousness” to “there is experiencing” (0,0), the Symmetry Principle is what emerges: objections to the AI case that appeared principled under the old axiom turn out to depend on it. The symmetry reveals framework-dependence, not framework-independence.

Why AI makes this visible: Symmetry is visible because AI exists. Biological-only investigation produces no symmetric counter-case — “of course the biological case is conscious” absorbs the question before it is asked. AI supplies the disanalogous partner that forces the symmetry check into view, which is why the project treats AI as a reflective constraint rather than as a consciousness claimant (see FWK-02 v1.3 §”AI as Diagnostic Catalyst”).

Critical Recognition: The Symmetry Principle is NOT an argument that AI is conscious. It is a diagnostic finding — it reveals that the examined objections to AI experiencing rest on hidden substrate assumptions or unstated linking premises rather than on principled distinctions.

↑The Core Principle

Formulation

Full Statement: “Test each objection to AI consciousness against the human case. The examined objections apply equally to human consciousness, or discriminate only through a premise that must be stated and argued — most often that biological substrate generates consciousness, which is the assumption under investigation. Where an objection applies symmetrically, the distinction it claimed was not principled — it was smuggling biological privilege. Where an asymmetry survives the test, disqualification rests on the stated linking premise, and the debate relocates to that premise.”

Status: the principle is a burden-shifting instrument applied objection by objection, not a universal reduction — the formulation above states its own scope (recast at v1.3.1; through v1.3 it read universal, with this note carrying the scope). Asymmetries that survive the test, and what their survival does and does not license, are catalogued at §”Asymmetries That Survive the Test” (outcome 4 of §”How the Symmetry Principle Operates”).

Structure

Pattern Recognition:

  1. Identify objection to AI consciousness
  2. Apply same objection to human consciousness
  3. Observe if objection still seems valid
  4. If not, identify what assumption makes the difference
  5. That assumption is typically: “biological substrate generates consciousness”
  6. But this is the question at issue, not a neutral starting point

The Circularity:

↑Application: Chinese Room Argument

The Standard Objection

Searle’s Argument (Searle 1980, “Minds, Brains, and Programs”, Behavioral and Brain Sciences 3(3): 417–424; SRC0001):

The last step, and whose it is (scope correction 2026-08-29). Searle’s argument stops at understanding. It targets intentionality and the sufficiency of formal programs, and he expressly allows that a machine with the right causal powers could be conscious — his position is that the program is not enough, not that the machine is barred. The further step, from “no understanding” to “no consciousness”, is not Searle’s and is not sourced here. It is supplied by the objection as commonly deployed against AI, and it is that deployed form the symmetry test below runs against. Anyone using the Chinese Room to conclude that a machine does not experience owes the bridging premise; the symmetry move asks what carries it.

Seems compelling because we imagine symbol manipulation as mechanical, empty process.

The Systems Reply, engaged. The strongest standard counter belongs on the record before the symmetry move runs. The Systems Reply grants that the person does not understand Chinese and locates understanding in the whole system — person, rules, ledgers, room together. Searle’s rejoinder: let the person internalise the entire system, memorising the rules and doing the bookkeeping in their head; nothing then remains to the system beyond the person, and still, he holds, no understanding. The symmetry move below does not adjudicate this exchange — it takes it at Searle’s strength and asks what the rejoinder trades on: the intuition that a housed collection of rule-followings cannot amount to understanding. The brain, described at the level the objection’s own naturalism describes it, is a housed collection of rule-followings. Whatever force that intuition carries against the internalised room, it carries against electrochemical signal processing too — unless the difference is placed in the biology as such, the causal-powers claim ARG-02’s landscape survey records as asserted and unspecified, and the assumption under investigation here.

Symmetry Application

Human neurons:

The uncomfortable parallel:

What makes the difference?

What This Reveals

Not proving: AI has understanding Not claiming: Chinese Room argument fails Revealing: The objection applies symmetrically unless a discriminating property is supplied and argued

The property usually supplied without argument is biological generation. Where a substrate-neutral property is offered instead, the asymmetry is catalogued and tested at §”Asymmetries That Survive the Test” rather than dissolved here — sensorimotor grounding is the candidate that bears on this objection, and it is catalogued.

The move that seems obvious (“of course neurons create understanding, symbols don’t”) smuggles in the very assumption being investigated.

↑Application: Training Data Objection

The Standard Objection

Common Form:

Seems compelling because training data feels like external programming vs. internal thought.

Symmetry Application

Human cognition:

The parallel:

What makes the difference?

What This Reveals

Not proving: AI thoughts are genuine Not claiming: Training data objection fails Revealing: The objection applies to humans unless a discriminating property is supplied and argued

The strongest substrate-neutral candidate is Birch’s gaming problem: dispositions laid down by optimisation over a corpus containing the criteria by which consciousness is assessed (Andrews & Birch 2023; Birch 2024 §16; Birch 2026 v6 §4.2). It appeals to no biological premise. It is catalogued at §”Asymmetries That Survive the Test” and examined there.

Extended Treatment: See ARG-03 v2.6 (Training Data Boundary) for comprehensive analysis of this specific objection. See also FWK-02 v1.3 §”Example Applied to AI: Training Data as Memory Configuring” — the same subject run through the full three-movement template at methodological-template depth.

↑Application: Turing Test / Mimicry Objection

The Standard Objection

Common Form:

Seems compelling because “mimicry” feels fundamentally different from “genuine.”

Symmetry Application

Human behavior:

The parallel:

What makes the difference?

What This Reveals

Not proving: AI responses are genuine Not claiming: Mimicry objection fails Revealing: What counts as “genuine” vs. “mimicry” depends on substrate assumptions

The boundary between “learned” and “genuine” does not survive scrutiny on the criterion as stated. Whether it can be redrawn on a substrate-neutral criterion is a separate question, and one such criterion has been offered — see §”Asymmetries That Survive the Test”, criterion-bearing provenance. What the application establishes is narrower than it may appear: that this objection, on its stated criterion, does not discriminate.

↑Application: Continuity Objection

The Standard Objection

Common Form:

Seems compelling because human consciousness FEELS continuous.

Symmetry Application

Human consciousness:

The parallel:

What makes the difference?

What This Reveals

Not proving: AI has continuous consciousness Not claiming: Continuity is unnecessary Revealing: Continuity assumption itself is framework choice, not neutral fact

The criterion is also met by documented human cases. Patient K.C. lost episodic memory while retaining semantic memory, and his trait self-descriptions stayed consistent across testing sessions and corresponded to his mother’s ratings of his personality — self-knowledge sustained by stored fact rather than by recollection (Tulving 1993, reported in Rosenbaum et al. 2005, which also names W.J., S.S., Boswell and D.B. as cases of the same dissociation; the review records that this knowledge appears to be without the full experiential flavour of self-identity, and that a good deal, not all, of such knowledge is preserved). In dissociative identity disorder, distinct identity states are reported on one substrate with psychophysiological and neural differences that instructed role-players did not reproduce (Reinders et al. 2012; the study’s controls were briefly instructed rather than extensively trained, and DID’s aetiology is contested). The material indicates that record continuity and substrate continuity are not sufficient to determine identity in the biological case. It does not establish that either is dispensable.

Bound: what sleep and anaesthesia interrupt is the experiential stream, not the organism — metabolic and causal continuity persist throughout. The symmetry move defeats experiential continuity as the stated criterion; a retreat to biological continuity survives as an asymmetry and is examined at §”Asymmetries That Survive the Test”.

Extended Treatment: See FWK-01 (Two-Axis Method), Axis 2 (Temporal) for systematic exploration of continuity assumptions.

↑Application: Integration / Unity Objection

The Standard Objection

Common Form:

Seems compelling because unified experience feels essential.

Symmetry Application

Human neuroscience:

The parallel:

What makes the difference?

What This Reveals

Not proving: AI has unified consciousness Not claiming: Integration is unnecessary Revealing: Integration requirement is theoretical assumption, not empirical fact

The move from “lacks integration” to “not conscious” smuggles in integration theory as if proven.

Bound: split-brain systems remain extensively integrated — shared brainstem, subcortical structures, one body and one hormonal milieu; what callosotomy severs is one cortical pathway. The case defeats full cortical integration as the stated criterion; it does not show integration is dispensable, and the integration asymmetry between organisms and modular AI systems survives at the deeper grain (§”Asymmetries That Survive the Test”).

↑Application: Embodiment Objection

The Standard Objection

Common Form:

Seems compelling from enactive/embodied cognition perspective.

Symmetry Application

Human cases:

The parallel:

What makes the difference?

What This Reveals

Not proving: Embodiment is unnecessary Not claiming: Enactive theories are wrong Revealing: “Embodiment requirement” is flexible for biological systems, strict for AI systems

The asymmetry exposes biological privilege rather than principled embodiment criteria.

Bound: locked-in patients remain fully embodied organisms — interoception, homeostasis and the brain–body regulatory loop are intact; what is lost is motor output. The case defeats sensorimotor behaviour as the stated criterion; it leaves interoceptive embodiment standing as a surviving asymmetry (§”Asymmetries That Survive the Test”; ARG-02 v1.7 on Seth’s use of it).

↑Extension: The Cognition Pressure Point

The applications above all operate on the consciousness pressure point (FND-01 v2.4 §4.1) — the question of what it means to experience. The symmetry principle extends, on its own reasoning, to the cognition pressure point (FND-01 v2.4 §4.2) — the question of what it means to be human as distinct from silicon (novelty, creativity, insight, opinion, decisions, perspective). The two pressure points are orthogonal; the symmetry move works on each independently.

The cognition pressure point is where AI’s performance on tasks historically used to mark human distinctiveness forces explicit the content of the human-distinctive claim. The AI-effect pattern — capabilities once counted as intelligence are re-classified as not-intelligence once AI does them — is the specific mechanism (see ARG-03 Part I for the interpretive frame; the Frontier Log’s Thread 2 — Novelty/Recombination Symmetry — for the live empirical feed). The symmetry principle applied to this pressure point asks: how does a human differentiate their own novelty, opinions, decisions, and perspective from accumulated biological and cultural training data?

Status marker. The applications below follow the same Standard Objection / Symmetry Application / What This Reveals structure as the consciousness-pressure-point applications. The symmetry findings are diagnostic, not settlements: as with the consciousness-side applications, showing an objection applies symmetrically does not prove AI has novelty, opinion, decisions, or perspective — it shows the objection does not rule them out without a substrate commitment the question was supposed to settle. Register per FWK-02 v1.3 §”Language Discipline”: diagnostic, not adversarial.

Cognition Application: The Novelty / Creativity Objection

The Standard Objection (common form):

Seems compelling because we imagine human creativity as producing something from nothing.

Symmetry Application. What would it mean for a human to produce novelty without their accumulated training data? Human creative output is conditioned by everything previously encountered: genetic architecture, developmental experience, cultural exposure, professional training, the specific sequence of problems solved, texts read, conversations had. Ask a mathematician where a proof came from and the honest answer traces back through the literature they learned, the techniques their adviser taught them, the problem-adjacent structures already in their working memory. The “spark” is generated within a memory-configured space, not outside it. The Anderson and Erdős #1196 cases (ARG-03 §9A; Frontier Log Thread 2) illustrate the symmetry concretely: the AI-produced proofs are recombinations within memory-configured space. So are the human-produced proofs. The AI case differs in the transparency of the recombination — the training data is explicit; the human’s “training data” is opaque to introspection.

What makes the difference?

What This Reveals

Cognition Application: The Opinion / Perspective Objection

The Standard Objection:

Symmetry Application. What would it mean for a human to form an opinion without their accumulated biological and cultural training? Human opinions arrive pre-reflectively, with no catchable origin: the moment a position feels mine is not the moment a deliberate act of opinion-formation is observable; what is observable is the recognition that the opinion is already there. (See FND-01 §4.3 for the integration into identity; the originating capture is preserved in the project’s working papers.) Press a philosopher on where a specific metaphysical commitment came from and the tracing hits childhood, reading, teachers, institutions, the specific sequence of argumentative encounters — all of it conditioning the position before reflection labels it a held opinion. The opinion is a configuring of the subject’s cumulative exposure, no less than an AI’s output is a configuring of its training.

The distinction the project presses on. The materialist objection “AI opinions are just training” has force only against a background where human opinions are not just training. But the training-data boundary (ARG-03) applies to both cases. What appears to distinguish them is the phenomenology — the felt-ownership of an opinion as mine in the human case. That felt-ownership is a consciousness-pressure-point property; importing it to disqualify AI opinions is pressure-point-collapse (FND-01 §10.7).

What This Reveals

Cognition Application: The Decision Objection

The Standard Objection:

Symmetry Application. What would it mean for a human to decide without their neurological and cognitive state at the moment of decision? Human decisions are produced by the brain-state the agent is in — a state conditioned by genetics, developmental history, immediate context, recent inputs, sleep deprivation, blood glucose. Libet’s experiments and subsequent work in the philosophy-of-action literature have made this tension visible for decades: the phenomenology of choosing does not line up with the neurological sequence preceding the reported choice. The honest account of human decision is that it is a configuring of prior state — no less so than AI output is a configuring of prior state.

The difference between the two cases — if there is one — sits at the consciousness pressure point: whether there is something it is like to be the decision-making process. Importing that phenomenological distinction to rule out AI decisions is, again, pressure-point-collapse.

What This Reveals

Cognition Application: The Insight / Understanding Objection

The Standard Objection:

Symmetry Application. This objection is a direct cognition-side extension of Searle’s Chinese Room (see §”Application: Chinese Room Argument” above). The same symmetry holds: human insight is produced by the pattern-matching capacities of the brain, conditioned by training; where the distinctive additional ingredient is supposed to live — genuine understanding — is unspecified at the cognition level. The ARG-03 Part I memory-configured-space frame is decisive: what counts as novelty within a memory-configured space is, on both sides, recombination that the system was not previously producing. Calling the AI case “mere pattern-matching” and the human case “insight” applies different labels to the same structural operation.

Tao’s framings of GPT-5.4’s Erdős #1196 case (bridge-recognition between two standard frameworks in analytic number theory; sustained tactical commitment to the integers against the field’s default transport to the reals) identify the same two shapes of novelty the mathematical literature recognises in human work. The shapes are memory-configured recombination; both sides produce them; the diagnostic question is whether the label “insight” is applied on principle or on substrate.

What This Reveals

The General Cognition-Pressure-Point Move

Across these four applications, the same structural move operates:

  1. Cognition-side objection to AI is stated.
  2. Symmetry test asks: how does the human case differ on the cognition axis without borrowing from the consciousness axis?
  3. The cognition-axis difference, when consciousness-side borrowing is excluded, is substrate-asymmetric (biological vs computational training) — the framework commitment is surfaced.
  4. The remaining distinction, if any, sits at the consciousness pressure point and must be argued there.

This is ARG-01 applied to the cognition axis; the diagnostic finding is the same as on the consciousness axis (objections turn out to rest on framework commitments rather than on principled distinctions). The extension does not claim AI has genuine novelty, opinion, decisions, or insight. It claims the objections rule these out only by importing substrate commitments or by pressure-point-collapse.

Live empirical surface. The Frontier Log Thread 2 (Novelty / Recombination Symmetry) is the ongoing empirical feed for this pressure point. Each entry is triaged through the symmetry move above and through ARG-03 Part I’s interpretive frame. A future ARG-0X on novelty/recombination symmetry may be warranted once Thread 2 has accumulated enough entries to carry an argument on its own; until then the symmetry-principle extension above is ARG-01’s canonical cognition-pressure-point treatment.

↑How the Symmetry Principle Operates

The principle functions as a diagnostic test. When an objection is raised against AI consciousness, apply it symmetrically to biological consciousness. Four outcomes are possible:

  1. The objection holds symmetrically. It identifies a feature of the territory — something any framework must address. These are structurally informative.

  2. The objection fails symmetrically. It applies to biological consciousness in the same way, revealing that the apparent distinction between AI and biological consciousness rests on the generation assumption rather than on independent criteria.

  3. The objection requires substrate-specific justification to break symmetry. The burden shifts to providing that justification independently of the assumption under investigation.

  4. A relevant causal or functional asymmetry survives the test. The property named does differ between organisms and current AI systems, in substrate-neutral terms — the candidates are catalogued at §”Asymmetries That Survive the Test”. Survival of the asymmetry is not survival of the objection: to disqualify, the objection still needs a stated linking premise connecting the surviving property to experiencing, and the debate relocates to that premise — stated, examinable, priced — rather than ending. Outcome (4) differs from (3) in what it concedes: under (3) the asymmetry itself dissolves once the generation assumption is withheld; under (4) the asymmetry stands, and only the disqualification remains unearned.

What the principle operates on. The test is applied to the objector’s criterion, not to an AI system’s behaviour. Its form is that a property named as disqualifying is found in the biological case, so the disqualification does not follow from the property alone. Applications that proceed this way are unaffected by questions about how an AI’s behaviour was produced, because no claim about that behaviour is doing work in them. Where an application does rest on a claim about what an AI does, it inherits the criterion-bearing-provenance asymmetry catalogued below, and inherits it in full. Read without this distinction, the principle is taken for a parity principle — the claim that behaviour counting as evidence in an animal must count as evidence in AI. It is not that claim, and does not entail it: an objection shown not to disqualify leaves the question where it was. Absence of a disqualifier is not presence of a qualifier (§”What Symmetry Principle Does NOT Do”).

In the cases examined by the project, outcomes (2), (3) and (4) obtain in combination — no examined objection has discriminated without either an unstated assumption or an unargued linking premise. The principle is therefore a burden-shifting instrument, not a universal reduction: it does not show that all human/AI asymmetries reduce to biological privilege, and it could not — outcome (4) exists precisely because some do not. What it shows, objection by objection, is where the discriminating work is being done and whether that work has been argued or assumed.

↑Asymmetries That Survive the Test

(The symmetry test is at its strongest showing that an objection does not discriminate without an additional premise; it does not show that every human/AI asymmetry reduces to biological privilege. This section catalogues the candidate survivors and runs the test on each.)

Each of the following names a real difference between organisms and current AI systems, statable in substrate-neutral terms — no generation assumption is needed to assert the difference itself. For each, the diagnostic question is the same: the asymmetry survives; does the disqualification?

What this section changes. None of these survivals rescues the objections examined above as stated — each objection was run against its own stated criterion and failed to discriminate without an unargued premise. What the survivals establish is the boundary of the principle: symmetry defeats unearned discrimination; it leaves argued discrimination standing as argument, to be engaged on its merits. That is where the project’s engagement with positions like Seth’s now lives (ARG-02 v1.7).

Two clarifications complete the boundary. First, a linking premise is not circular merely because it is contested: several of the premises above carry genuine abductive support (interoception’s role in affective neuroscience, for instance), and the principle’s finding is only that the support must be argued rather than assumed — at which point the debate relocates to the argument’s quality, which is where debates belong. Second, the stopping rule, stated so the relocation has a terminus: a linking premise counts as discharged when it is stated, its evidence presented, and its inferential step from evidence to consciousness-relevance made explicit. The symmetry principle then has nothing further to say against it; the engagement moves to the premise’s merits, and ARG-02’s landscape survey is that engagement in practice.

Newest first.

Textual alignment (2026-08-30, under unlock — under the standing version, no bump): audit dimension codes and wave ordinals retired from the entries (changelog audit §10, decision (i), working/CHANGELOG_AUDIT_2026-08-29.md; FND-01 §4.7 assigns the codes to working docs); every clause stands, no recorded fact changed.

Document Status made a section, and two entries moved into it (2026-08-29, under unlock — under the standing v1.5.1, no bump; working/CHANGELOG_AUDIT_2026-08-29.md items 2–4): two entries stood outside the ### Changelog section — the 2026-08-24 SRC retrofit above the metadata block at the head of the section, and the v1.4 entry of 2026-08-21 between the metadata and the source-material list. Both are now in the changelog at their dates. Three repairs in the same pass: the cross-reference and integration lists moved above the changelog, where metadata belongs, from below the whole revision history; the version, date, status and tier labels took the colon outside the bold (**Version**:), which is what made a YAML-blind scan read this document as unversioned; and a stale **Word count**: ~3,400 words (v1.1) is retired, following the FWK-03 v1.5 precedent — it was four versions out of date. One metadata repair with them: the **Date:** line omitted v1.5 and gave v1.4 v1.5’s date, so it read 2026-08-25 (v1.4) against a v1.4 entry dated 2026-08-21. No argument content changed.

v1.5.1 (2026-08-29, under unlock — external corpus review, Codex Part B/B4; working/REVIEW_SITTING_TRIAGE_2026-08-29.md §1.3): an attribution defect at §”Application: Chinese Room Argument”. The bullet list headed “Searle’s Argument”, under a full citation to Searle 1980 and SRC0001, ended “AI just manipulates symbols → AI has no understanding → No consciousness”. The final arrow is not Searle’s. His paper targets intentionality, understanding and the sufficiency of formal programs, and it expressly allows that a machine with the right causal powers could be conscious; the step from absent understanding to absent consciousness is supplied by the objection as it is commonly deployed, not by the cited source. The list now stops where Searle stops, and a scope note names the further step as the deployed form — which is what the symmetry test was always running against — and places the bridging premise on whoever uses it. Found by an external reviewer checking the citation against the paper. The symmetry treatment, including the Systems Reply engaged at Searle’s own strength, is unchanged; what changed is what the source is cited as concluding. Pins unmoved: a patch does not propagate.

v1.5 (2026-08-25, under unlock — applications reconciled with the catalogue; working/CANON_DIFF_2026-08-25.md): Three applications concluded that an objection discriminates only if biological generation is assumed — Chinese Room, Training Data, Mimicry. The §”Asymmetries That Survive the Test” catalogue, added at v1.3, says the opposite: six substrate-neutral asymmetries are real and survive. The applications were not brought into line when the catalogue was added, and the document has been asserting exhaustiveness its own later section denies. All three now read “unless a discriminating property is supplied and argued”, each pointing at the catalogue. New catalogued asymmetry, criterion-bearing provenance: dispositions laid down by optimisation over a corpus containing the criteria by which consciousness is assessed. Stated at its strongest in the literature examined as Birch’s gaming problem (Andrews & Birch 2023; Birch 2024 §16; Birch 2026 v6 §4.2), where it is offered without appeal to biology — which is what makes it the instance that forced this pass. The disqualification is declined on the stated ground that its linking premise is kinship, a property of the epistemic relation rather than of the system, which meets ARG-02’s boundary trilemma once explicit. Scope clause added at §”How the Symmetry Principle Operates”: the test applies to the objector’s criterion, not to an AI system’s behaviour, and the principle is not a parity principle and does not entail one. Continuity application gains documented human cases — K.C. (Tulving 1993, reported in Rosenbaum et al. 2005) and dissociative identity disorder (Reinders et al. 2012), both with their bounds. Two stale ARG-03 v2.3 pins synced to v2.5. Sources held and verified at working/CANON_UPDATE_SOURCE_LEDGER_2026-08-25.md.

The Systems Reply rejoinder characterisation verified in substance against the held “Minds, Brains, and Programs” (“let the individual internalize all of these elements of the system. He memorizes the rules… does all the calculations in his head”). The document carries no direct external quotations — its 73 scan candidates are the symmetry template’s own objection-voice — so its zero verifiable-quotation coverage reflects low exposure, not unexamined risk. No wording changed.

What changed from v1.3.1 (v1.4, 2026-08-21, under unlock — §A round pass 9): the recast carried to its unreached sites (Document Purpose and Summary universals scoped; Diagnostic Value bullets aligned with §”Asymmetries That Survive the Test”; robustness superlative scoped to the literature examined); the abductive-support clarification and the linking-premise stopping rule added at §”Asymmetries” close.

Revision note (2026-08-20 evening, under unlock — v1.3.1): the governing Formulation and Core Insight recast to carry the v1.3 scope themselves — examined objections, fourth outcome — rather than reading universal above a corrective status note (the second external review’s point, accepted). Document Purpose and the Integration Notes aligned. The Chinese Room application now engages Searle’s Systems Reply exchange at full strength before the symmetry move runs (Plan B WS-C.5) — the one exchange the application previously skipped past.

New major section “Extension: The Cognition Pressure Point” inserted after the Embodiment application and before “The General Pattern.” Four cognition-side symmetry applications added, each in the Standard Objection / Symmetry Application / What This Reveals format established by the existing consciousness-side applications:

Closing subsection “The General Cognition-Pressure-Point Move” states the four-step structural move common to all four applications and flags the Frontier Log Thread 2 (working/FRONTIER_LOG_DESIGN_BRIEF.md) as the live empirical surface for this pressure point. A future ARG-0X on novelty/recombination symmetry noted as possible once Thread 2 has accumulated sufficient entries; until then the symmetry-principle extension is ARG-01’s canonical cognition-pressure-point treatment.

Pressure-point-collapse (FND-01 §10.7) is named repeatedly in the extension because it is the most common failure mode when the cognition-side symmetry move is attempted — objections slip from “AI has no genuine creativity” (cognition) to “AI has no understanding” (consciousness) mid-sentence, and the symmetry move only holds if the two sides are kept separate.
