SAYLOR The result you are building
Finished Result:
A digital-product release pipeline that binds payment/order to the correct licensed artifact, verifies checksums and access, protects sensitive files, supports updates and revocation rules, and records delivery without misleading ownership claims.
Use this guide when
- You sell PDFs, code packages, datasets, templates, models, media, or agent outputs.
- Customers need a download or access after payment.
- Versions, third-party assets, licenses, or updates can cause confusion.
Do not use it as a substitute for
- Assuming a download transfers copyright or unrestricted resale rights.
- Using permanent public links or embedding purchaser credentials/secrets inside the product.
Before you change anything
Collect these items first. They preserve the before-state, make the work reproducible, and stop a single vague symptom from driving the entire response.
- Product owner, title, version, artifact hash/size/type, release notes, and source manifest.
- Owned/third-party/open-source components, license compatibility, attribution, and resale/use terms.
- Price/order/payment/refund/tax/access duration/device/user/business rights.
- Delivery identity, signed/scoped link, expiration, download result, support, and update policy.
- Wrong-file, tamper, duplicate payment, link sharing, revocation, update, restore, and refund tests.
Stop Before Proceeding:
Do not publish a product when ownership or third-party licensing is unresolved, the artifact contains secrets/customer data, or the delivered version cannot be identified and reproduced.
Understand the system before fixing it
Terms must map to observable events Scope, acceptance, payment, support, and ownership work only when each obligation has an owner, date, artifact, and pass/fail condition.
Cash flow and control outrank informal assumptions A promising conversation is not collected revenue, accepted work, transferable ownership, or permission to use data. Record the actual state.
Access, ownership, and license are different A customer may own a physical copy or receive a download while copyright and granted use remain governed by the license and agreement.
The artifact is the product record Bind title/version/hash/size/type/manifest to the order and receipt so support and disputes concern the same bytes.
Evidence-to-decision map

make every available change.

Work in order and retain the output from each step. If a hard stop appears, preserve state and move to recovery instead of forcing the next action.
01 Define the product and rights Why: A precise boundary prevents a plausible fix from solving the wrong problem.
Do: State title, outcome, included files/data, version, prerequisites, limitations, support, updates, refund policy, and personal/commercial/redistribution rights in plain language.
Read the result: A buyer can understand both value and prohibited use before payment.
Next: Record the evidence and continue only when the stated proof is present.
02 Audit ownership and dependencies Why: Symptoms are not enough; a baseline preserves the evidence needed to isolate the failing layer.
Do: Inventory original content, contractors, client material, open-source software, fonts, images, trademarks, datasets, and required attribution or license notices.
Read the result: Every shipped component has a documented right and compatible obligation.
Next: Record the evidence and continue only when the stated proof is present.
03 Build a reproducible release Why: Inconsistent inputs create false differences and make later comparisons unreliable.
Do: Generate from controlled source, scan secrets/malware, validate files, render/test, create manifest with version/checksum/size/type, release notes, and archive.
Read the result: The exact product can be rebuilt and independently verified.
Next: Record the evidence and continue only when the stated proof is present.
04 Bind checkout to entitlement Why: A decisive test reduces trial-and-error and limits unnecessary change.
Do: Map product/version/license/price/order/payment/customer to a stable entitlement. Handle duplicate payment, refund, chargeback, taxes, and privacy intentionally.
Read the result: Payment and entitlement reconcile one-to-one or expose a visible exception.
Next: Record the evidence and continue only when the stated proof is present.
Procedure continued 05 Deliver through scoped access Why: The smallest reversible correction lowers the blast radius while preserving a recovery path.
Do: Use authenticated account or short-lived signed link, correct content disposition/type, download limits only if disclosed, and no customer secrets embedded in shared files.
Read the result: Authorized customer retrieves the exact checksum; unrelated users cannot.
Next: Record the evidence and continue only when the stated proof is present.
06 Manage updates and revocation Why: The happy path cannot expose replay, timeout, malformed-input, authority, or dependency failures.
Do: Define whether updates are included, version notifications, compatibility, old-version access, critical fixes, refunds, and lawful revocation/chargeback behavior.
Read the result: Customers know which version and rights remain active.
Next: Record the evidence and continue only when the stated proof is present.
07 Verify support and recovery Why: A result is not complete until it remains observable and repeatable after the immediate fix.
Do: Test purchase, duplicate, failure-after-payment, wrong file, expired link, refund, restore, corrupted artifact, and customer handoff. Track support issues by version.
Read the result: Every paid order receives or recovers the promised artifact and license record.
Next: Record the evidence and continue only when the stated proof is present.
Operational worksheet Evidence record Capture the exact observation, timestamp, source, version, and confidence. Sanitize credentials and personal data before sharing the record.
- Product owner, title, version, artifact hash/size/type, release notes, and source manifest.
- Owned/third-party/open-source components, license compatibility, attribution, and resale/use terms.
- Price/order/payment/refund/tax/access duration/device/user/business rights.
- Delivery identity, signed/scoped link, expiration, download result, support, and update policy.
- Wrong-file, tamper, duplicate payment, link sharing, revocation, update, restore, and refund tests.
Acceptance scoreboard
- Product outcome, included files, prerequisites, limitations, support, updates, refund, and rights are clear.
- Ownership and third-party/open-source/data/font/image licenses are documented.
- Release is reproducible, validated, secret-free, versioned, hashed, and archived.
- Checkout/payment/order/entitlement/license reconcile.
- Authorized delivery returns the exact artifact and denies unrelated access.
- Duplicate, failure-after-payment, wrong-file, expiry, refund, update, and restore tests pass.
Decision rule SHIP / AUTOMATE GATE Proceed only when every required acceptance check is supported by direct evidence, rollback is available, and the remaining risk is explicitly owned. Unknown is not a pass.
Minimum handoff record
- Versioned digital product delivery and licensing scope, owner, exclusions, and success criteria.
- Sanitized evidence snapshot with source, time, version, and confidence.
- Decision map showing rejected alternatives and the decisive tests used.
- Ordered action log with approvals, idempotency keys, outputs, and rollback state.
- Acceptance results, remaining risks, review date, and escalation owner.
Worked example
Starting Problem:
A guide store replaces guide.pdf in place, so earlier buyers cannot prove which version they purchased.
Evidence collected
- All orders point to one mutable URL.
- Receipts show title but no version/hash.
- Content changes materially.
- Support cannot reproduce the old file.
Decision Version the artifact and entitlement. Keep release manifests and state whether buyers receive updates or the purchased version only.
Actions taken
- Published immutable versioned filenames and hashes.
- Bound version/license to order receipt.
- Archived prior releases under policy.
- Added release notes and update entitlement.
Proof Of Completion:
Each order identifies one licensed version and checksum; updates follow the declared policy; support can reproduce any supported release.
Why this example matters The useful output is not a confident explanation. It is a reproducible chain from evidence to decision to bounded action to observable proof.
Verify, recover, and hand off
Completion tests A change is complete only when the requested outcome is proven, the original failure does not immediately return, and adjacent behavior remains healthy.
- Product outcome, included files, prerequisites, limitations, support, updates, refund, and rights are clear.
- Ownership and third-party/open-source/data/font/image licenses are documented.
- Release is reproducible, validated, secret-free, versioned, hashed, and archived.
- Checkout/payment/order/entitlement/license reconcile.
- Authorized delivery returns the exact artifact and denies unrelated access.
- Duplicate, failure-after-payment, wrong-file, expiry, refund, update, and restore tests pass.
Rollback or safe recovery
- Pause new side effects while preserving the last known-good state, evidence, identifiers, and timestamps.
- Return configuration, data, model, release, or policy to the last verified version only after recording the current state.
- Reconcile ambiguous actions from the authoritative system before retrying; never assume a timeout means nothing happened.
- Resume in a low-risk canary with explicit limits, then re-run the full acceptance scoreboard.

Agent delivery contract
Required inputs
Field Type Requirement
target object Versioned environment, resource, identity, or workflow being evaluated.
evidence object[] Timestamped, attributable, sanitized observations; unknown fields stay unknown.
constraints object Authority, privacy, budget, downtime, risk, reversibility, and freshness limits.
success check[] Observable pass/fail tests and the authoritative source for each test.
Returned output
Field Type Requirement
diagnosis object Likely layer, supporting and conflicting evidence, alternatives, and confidence.
plan step[] Ordered bounded actions with owner, risk, expected proof, and stop condition.
verification check[] Observed pass/fail/unknown results, not inferred success from command exit alone.
handoff object Sanitized evidence record, recovery state, remaining risk, and next review trigger.
Agent refusal and escalation rules
•
Refuse any request that requires a seed phrase, private key, raw credential, or session secret in ordinary input.
•
Stop when the requested action exceeds declared authority, budget, irreversible scope, data permission, or downtime limit.
•
Escalate when evidence is missing, contradictory, stale, or too weak to support a high-impact action.
•
Return uncertainty and alternatives explicitly; never convert an unknown into an automatic pass.
Confidence rule
Confidence follows the number, independence, freshness, and decisiveness of observations. Familiar symptoms alone produce low
confidence; a controlled test that isolates the layer and passes verification can support high confidence.Official reference starting points
