Map standard and custom operations
Map lookup, calculation, write and notification and mark custom logic. A connector name does not establish that every required operation exists. A code requirement is not automatically a disadvantage; assess it alongside the availability of a maintainer and a clear rule specification.
Distinguish builders and business operators
Consider whether someone inspecting results needs permission to change the logic. Verify actual role separation in the applicable offers. A useful handoff test asks whether an operator can identify unfinished or failed work without the original builder narrating every step.
Evaluate edition scope, not licence headlines
Separate a free self-hosted start from paid administrative entitlements on both sides. Map placement, identity, audit and external-user requirements to the appropriate edition. Running on a private server alone is not evidence that every required access or historical control is available.
Normalize the full month of work
Apply role, compute and credit descriptions to the same inputs and outputs for a month. Separate base charges, extra consumption, upstream APIs and maintenance. A replay assumption should be labelled as a sensitivity scenario until observed, rather than presented as a measured reliability result.
A hypothetical reviewed-request workflow
Consider a hypothetical request reviewed by a person before a register update. Distinguish waiting, returned and changed-after-approval states. In either candidate, separate review from execution authority and test that unapproved input cannot proceed to a live record change.
Preserve a portable operating specification
Retain logic, action mapping, stored state and connection ownership. Identify what a future move must rebuild, and separate saved configuration from legitimate secret-access transfer. If staffing changes, review the operating model rather than continuing solely because an installed edition has no licence fee.
Compare a change, not only the first build
Simulate an upstream field-name change and locate affected input, transformation, register and notification logic. Check whether one maintained component fixes it or repeated rules are embedded across several flows. Record locating and validating the change, not only initial build effort. A configuration with an understandable specification may fit continuing ownership better than one that was quicker for its original author.
