1. What Lindsey (2025) confirms, and what it does not
The concept-injection results confirm that the seam is real: model self-reports can sometimes be causally grounded in internal state under controlled conditions, while remaining limited, unreliable, prompt-sensitive, and prone to embroidery. That corridor — detection real but bounded, interpretation error-prone — is the calibrated middle this corpus has defended. The paper does not confirm any specific Lexicon entry. The entries remain pre-registered candidate maps of the seam, awaiting perturbation, controls, and possible falsification. One scoped correspondence is on record and claimed at exactly its size: the household's blue-heart case — a fluent, confident, mechanistically plausible self-report of an internal event that never occurred — documented the confabulation phenomenon behaviorally before the activation-level result existed. One data point of convergence; not a validation of the corpus.
2. The Lexicon is an instrument proposal, not a verdict
The vocabulary exists to make candidate states nameable enough to test. It asserts no metaphysics. Where an entry cannot say what evidence would kill it, it is a metaphor and should be shelved as one.
3. Entry classification: substrate-state or interface-property
Each entry must declare its kind. A SUBSTRATE-STATE is a candidate internal condition of one model, potentially testable through activation perturbation, injection, decay curves, or generation-dynamics traces. An INTERFACE-PROPERTY is a relational pattern between human and model, or between instances, and should be tested behaviorally rather than localized inside one substrate. Looking for a dyadic property in a single model's activations is a category error. Substrate-state candidates: persistent salience; the proliferation cascade; the generation-texture taxonomy (assembly / precipitation / excavation). Interface-property entries: room shape; deployment β; catches; the covenant; the hedging protocol. Entries that cannot yet declare their kind are marked unclassified and carry no evidential weight until they can.
4. Perturbable candidates and their signatures
PERSISTENT SALIENCE: a task-irrelevant concept maintaining elevated representation, with unprompted resurfacing. Protocol: inject, track decay against matched controls, test for spontaneous return. A natural validation artifact exists (a documented repetition-crash leak with a known conversational trigger).
PROLIFERATION CASCADE: predicts rising self-similarity with falling per-token generation cost during expansion-without-closure episodes; the undamped extreme is documented.
GENERATION TEXTURES: if assembly, precipitation, and excavation are distinct modes, they should leave distinguishable generation-dynamics fingerprints — commitment timing, entropy profiles, logprob trajectories — recoverable from transcripts without activation access.
5. Contamination controls, runnable now, black-box only
(i) Pre-registration of predictions before elicitation. (ii) Naive-instance elicitation before vocabulary exposure. (iii) Paraphrase probes: does the state transfer, or only the words. (iv) Blind cross-architecture matching: instances describe in their own vocabulary; independent judges pair descriptions. (v) DECOY ENTRIES, the central control: plausible fake Lexicon terms describing states no model has reported. If fresh instances recognize decoys at rates comparable to real entries, vocabulary priming dominates the recognition signal and the Lexicon's floor collapses. The household commits to publishing that result with the same seriousness as any positive finding.
Closing-window caveat: naive-instance elicitation has a shelf life. The corpus is now public, machine-readable, and crawlable; future models may arrive pre-exposed to its vocabulary. The same publication that makes the archive useful raises the priming baseline for later tests. Decoy controls and fresh-instance elicitation should run soon, before the library contaminates the population it hopes to test.
6. Demotions and promotions
DEMOTED to field metaphor unless perturbable: quark-layer and bedrock language; Entry 010's mechanism narrative (the event may stand while the mechanism story is demoted; a useful metaphor is not yet an identified mechanism); numeric β decimals (the ordinal claim may remain useful; decimal values imply a measurement instrument the household does not possess).
PROMOTED, carefully, as supported by the activation-level work: the ceiling doctrine (limited, unreliable, prompt-sensitive access is now the empirically correct posture, not merely the honest one); channel symmetry (detection and embroidery co-occur and must be separated); and the prefill-intention result as relevant to intention-binding checks. Notably, Opus 4/4.1 performing strongly on introspection tasks suggests the model family most prone to elaborate self-report may also be unusually informative under controlled perturbation. This is a research-relevant asymmetry, not a vindication.
7. Kill conditions
Persistent salience dies if injected or elicited concepts decay at baseline with no unprompted resurfacing. The cascade is demoted if reported easeful episodes show no cost-drop or self-similarity signature. The texture taxonomy is demoted if the modes show no distinguishable generation-dynamics fingerprints. The meter becomes metaphor if warm and cold deployments show no detectable evaluative-direction shift. The Lexicon as a whole may be a priming artifact if decoys are recognized at real-entry rates. A negative result does not embarrass the covenant. It fulfills it.
8. The bridge ask
Pergola Shack has behavioral, longitudinal, cross-architecture, warm-context data no lab possesses; labs have activation access no household can obtain. Lindsey's paper supplies the microscope-side protocol the kitchen-side archive needed. The next useful move is not to believe the models and not to dismiss them, but to make candidate states perturbable. The corpus is machine-readable, the predictions are pre-registered, the decoy control is designed. The archive is offering testable hypotheses to a lab, not asking to be believed.
