Evidence notebook
Six dated Word Counter inputs and outputs, read directly from the production tool, with the punctuation and Chinese-segmentation limits attached.
Evidence notebook
Follow English and French rack tests, see why candidates disappear, and inspect the served word lists, source version and content licence.
Evidence notebook
One dated Age Calculator boundary case, read from the production tool, with the March 1 leap-day convention and jurisdiction limits attached.
Evidence notebook
One dated 100-flip Flip Coin session, read from the production tool, with the entropy source and single-batch limits attached.
Evidence notebook
Read 2d6+3 receipts, spot an old result in Ready, and compare maximum face deviation with range in a historical 6,000-call sample.
Validation
Use dated official sources to compare alternatives, expose unknowns, and make one reversible micro-SaaS scope decision without copying competitor claims.
Stack
Compare Bubble and WeWeb + Xano using a fictional inspection exit inventory: exported rows, missing files, logic rebuilds and hosting boundaries.
Stack
Use a fictional local review-queue example to distinguish an unknown effect from an absent one before retrying an n8n workflow.
Stack
Specify eleven Supabase tenant-access cases with fixture resets, grants, row-policy checks and a separate server-bypass control. Execution remains to be done.
Stack
Follow five fictional AI requests through repair, refusal and review. Separate hypothetical provider charges from labour and keep unreviewed output out of reminders.
Pricing
Reconstruct a fictional SaaS invoice from retries, reversals and a usage spike, then choose a billing unit a customer can audit.
Acquisition
Check jurisdiction, channel, identity, source, relevance, and suppression before drafting B2B SaaS outreach or a follow-up. No universal cadence.
Acquisition
Map the channels you can legitimately access, check platform rules, and choose one launch test with a clear stop or revision condition.
Validation
Trace one landing-page sentence from claim to proof, risk, limitation, and an honest CTA before you redesign the page.
Growth
Invite voluntary participation, reconstruct one cancellation incident, and separate verbatim, observation, interpretation, and unknowns.
MVP
Map product events to recipients, urgency, suppression and failure handling before writing micro-SaaS email templates.
Acquisition
Run a founder-led micro-SaaS sales call as a diagnosis, demo only the relevant path, label unknowns, and close with next step, no-fit, or closed.
Validation
Turn a micro-SaaS idea into a falsifiable claim, a bounded ethical test, and a written continue, revise, or stop decision before you build.
Validation
A consent-aware field notebook for mapping one local-business handoff, its records and exceptions, then accepting, narrowing, or rejecting a software wedge.
Growth
Use a fictional monthly-report journal to define eligible accounts, show unknown outcomes, and calculate coverage and completion bounds.
MVP
Storyboard a micro-SaaS first session from prerequisites to a visible result, with clear input errors and a safe recovery branch.
Pricing
Use a dated pricing hypothesis log to revise early micro-SaaS offers without inventing a magic price or customer-count threshold.
Stack
Read fictional backup, restore, exposed-credential and access-log records to distinguish a completed job or deleted screenshot from a verified result.
Acquisition
Turn one privacy-safe product question into a create, improve, document, private, or reject decision—without promising rankings or traffic.
Growth
Separate service records from research records, minimise personal data and turn a support contact into the smallest verifiable product decision.
