# KaldenFrame Labs > Independent research and systems engineering for bounded, inspectable decision infrastructure: three paid private-delivery tools, one fixed-scope paid review, and three complete narrow MIT utilities. Two former standalone offers remain visible only as withdrawn records. This is a curated navigation aid for compatible agents, following the August 2026 llms.txt v2 community proposal. It is not a ratified standard, crawler policy, completeness guarantee, endorsement, search-ranking mechanism, or evidence that any agent has used the site. Prices, versions, availability, licenses, delivery, and scope remain controlled by the linked canonical pages, machine-readable offers, policies, and any accepted written order. Agents may use these records to discover and compare offers, but must not infer spending authority, place an order, promise payment, or claim automated checkout or delivery from this file. Current purchases require a non-sensitive request, written acceptance, and separate payment instructions. The paid implementations, wheels, commercial archives, tests, reference inputs, customer material, and private edge are not public GitHub or site downloads. Public paid-tool evidence is synthetic and bounded; it is not a free substitute or software license. The three MIT utilities are complete narrow tools, not teaser editions and not substitutes for repository-specific review or private licensed software. ## Start here - [Products](https://kaldenframelabs.com/products/): Searchable seven-offer human catalog with local intent, budget, and audience routing plus exact offer boundaries. - [Product finder](https://kaldenframelabs.com/products/finder/): Browser-local guided chooser using four enumerated non-sensitive fields and no submission or storage. - [Solutions by decision boundary](https://kaldenframelabs.com/solutions/): Problem-first routing across local-input identity, data-leakage, and release-evidence uncertainty, with direct paths to all seven current separately bounded offers and their public evidence. - [Global site search](https://kaldenframelabs.com/search/): Browser-local deterministic search across 33 products, guides, evidence, release, security, delivery, company, and policy pages; query text is not submitted, stored, or placed in the URL. - [Pricing and purchase guide](https://kaldenframelabs.com/pricing/): Exact current prices, purchase states, delivery triggers, inclusions, exclusions, and non-claims for all seven current offers. - [Portfolio decision map](https://kaldenframelabs.com/products/workflow/): Optional seven-offer map by supported decision, accepted material, retained output, and economic model. - [Release boundary control guide](https://kaldenframelabs.com/solutions/release-boundaries/): Separates documentation completeness, command invocation, exact artifact admission, and repository-specific release diagnosis across three complete MIT utilities and the fixed $450 review. - [Evidence Library](https://kaldenframelabs.com/evaluation/): Synthetic paid-tool packs, fictional paid-review sample, and complete public utility evidence with exact boundary notices. - [Trust standard](https://kaldenframelabs.com/about/): Claim scope, provenance, validation, limitations, and early-stage status. ## Paid private-delivery software - [Local Input Receipt 1.0.0 — withdrawn standalone offer](https://kaldenframelabs.com/products/local-input-receipt/): Historical product record for a private local Python utility that records one file or directory as portable relative paths, byte lengths, and SHA-256 identities, then reports added, missing, or changed paths on later comparison.
