2026-05-30 | 🪪 Mechanism Decorator Cleanup Closes With Impl 🧹

🎙️ What This Pull Request Does

🧹 This change is the third and final step of the mechanism decorator cleanup campaign, and it targets the implementation suffix in the PureScript foreign function interface modules for the word meter feature. 🪪 The agents file forbids mechanism flavored suffixes like implementation on identifiers because they describe how a value was produced rather than what the value represents at the call site, and the canonical pattern in the rule is to give the wrapper its own concept level name and to give the foreign import a different concept level name that describes the JavaScript side capability it exposes. 🧪 Five foreign imports across three foreign function interface modules carried the implementation suffix, and each one has been renamed to a concept level name that reads clearly at every call site, with the companion JavaScript export updated in lockstep so the foreign function interface still resolves cleanly.

🧭 Why Implementation Came Last

🔍 The fresh whole word audit that opened this campaign turned up ten implementation suffixed identifiers, all inside three PureScript foreign function interface modules, and every one of them paired a foreign import with a wrapper that interprets the return value into a domain Either. 🪪 Picking the implementation cluster last preserves the rhythm the earlier helper and raw steps established, where a single contained scope gets its own pure rename pull request and its own blog entry. 🥇 With implementation cleaned up, the audit hot spot for mechanism decorator suffixes is fully resolved across the active source code, which is exactly the cadence the previous campaigns aimed for.

🪪 What Got Renamed

🪟 The confirmation foreign function interface used to expose a foreign import called ask for confirmation implementation, and it now reads as run window confirm, which spells out that the JavaScript layer opens the browser confirm dialog. 🗄️ The persisted storage foreign function interface used to expose three foreign imports called read persisted string implementation, write persisted string implementation, and clear persisted string implementation, and they now read as read js raw string, write js raw string, and clear js raw key, which is exactly the example pair the cleanup plan suggested for storage capabilities. 🎙️ The speech recognition foreign function interface used to expose a foreign import called ensure on device language pack implementation, and it now reads as run on device language pack preflight, which describes the actual JavaScript side capability that walks the available and install round trip. 🪞 The PureScript wrappers ask for confirmation, read persisted string, write persisted string, clear persisted string, and ensure on device language pack all kept their public domain names, because their job is to interpret the foreign function interface outcome into a domain typed Either rather than to perform the underlying capability themselves.

🛡️ Why This Is A Pure Rename

🔬 No behavior changes shipped in this pull request. 🧰 Each rename is a textual swap of an identifier inside the foreign function interface modules and their companion JavaScript exports, with no edits to the call sites that consume the wrappers. ✅ The PureScript bundle still builds clean, the warning surface is identical to the previous build, and every PureScript unit test still passes its full hundred iteration sweep on every property, exactly as before.

📋 The Plan The Campaign Lives In

📜 The mechanism decorator cleanup plan in the specs directory has been updated to mark the implementation step as shipped, alongside the helper and raw steps that landed earlier in the campaign. 🧭 The plan now records the full rename mapping from each implementation suffixed foreign import to its concept level replacement, so any future agent reading the plan can see exactly how the canonical wrapper plus capability pattern was applied here. 🪜 As with every previous cleanup plan, the final step is a fresh agents file audit that finds the next most violated rule and starts the next plan, which keeps the engineering excellence improvements rolling forward as a steady stream of small focused pull requests.

🧱 What Comes Next

➡️ With the mechanism decorator cleanup closed out, the next step in the wider engineering excellence campaign is a fresh whole repository audit against the agents file checklist to find the next most common aberration. 🧩 The follow up issue will capture the audit evidence, write a new spec under the specs directory naming the targeted rule, and break the remediation into pure rename pull requests that mirror the cadence of the abbreviation cleanup, the single letter variable cleanup, and the mechanism decorator cleanup that just shipped. 🔁 Each of those campaigns has shown that small, contained, well documented pull requests are the way the codebase compounds discipline over time, and the next campaign will continue that pattern.

📚 Book Recommendations

📖 Similar

• The Pragmatic Programmer by Andy Hunt and David Thomas is relevant because its long argument for naming values after their meaning rather than their origin is exactly the rule the implementation rename enforces in the foreign function interface modules.
• 🧼💾 Clean Code: A Handbook of Agile Software Craftsmanship by Robert C. Martin is relevant because its chapter on names singles out type and mechanism suffixes as noise that obscures the concept the reader actually cares about, and the implementation suffix is the textbook example for this final cleanup step.
• A Philosophy of Software Design by John Ousterhout is relevant because its emphasis on naming for the reader at the call site lines up with replacing implementation flavored foreign import names with capability flavored foreign import names.

↔️ Contrasting

• Hungarian Notation As A Cure For The Ailments Of C by Charles Simonyi is relevant because it argues for encoding origin or representation information directly in the name, which is the exact opposite of the rule this cleanup enforces and a useful counterpoint to consider.
• The Mythical Man-Month by Frederick P. Brooks is relevant because its sympathy for short term tactical compromises in growing systems contrasts with the agents file insistence on rolling small compliance fixes through the entire repository as a long running campaign.

🔗 Related

• Refactoring by Martin Fowler is relevant because its catalog includes the rename function move as the smallest unit of refactoring, and the implementation step in this campaign is a textbook application of it across three foreign function interface modules.
• ✅💻 Code Complete by Steve McConnell is relevant because it surveys decades of naming research and reaches the conclusion that names should describe meaning and capability rather than implementation or origin, which is exactly the move from implementation flavored foreign imports to capability flavored foreign imports.
• Domain-Driven Design by Eric Evans is relevant because its argument for naming bindings after the domain concepts they represent lines up with the renaming of the foreign function interface entry points from implementation flavored labels to capability flavored labels.
