Closes #3114

Summary

PromptManager::runProcessors() no longer keeps its own ordered list of all 41 handler IDs: each handler declares processWeight() on HandlerInterface, and getProcessHandlers() sorts the registered set by it. runPostBuild() likewise asks every handler instead of polling a hard-coded Starter, HostingProvider, CiProvider trio in which Starter has no postBuild() at all, so that slot did nothing.

Both lists had to be edited by hand whenever a handler was added or removed, and nothing failed when one was missed: a handler could discover and prompt correctly yet never process. The progress denominator had the same problem in a milder form, with const TOTAL_RESPONSES = 36 sitting below the 39 prompts the chain actually defines, so the suffix could read (39/36).

runPrompts() is deliberately unchanged. It is the catalogue of prompts, and the form() chain listing every prompt in order under its section heading stays exactly as it was, down to which prompts receive the collected responses. The denominator is now counted from that chain by countPrompts(), so adding a prompt there updates it with no second edit.

Before / After

Before
┌──────────────────────────────────────────────────────────┐
│ runPrompts()      form() chain - the prompt catalogue    │
│ runProcessors()   hand-written list of all 41 handlers   │
│ runPostBuild()    hand-written list of 3 (1 dead slot)   │
│ TOTAL_RESPONSES   36, against 39 prompts in the chain    │
└──────────────────────────────────────────────────────────┘
      adding a handler = 4 edits, 3 of them silent if missed

After
┌──────────────────────────────────────────────────────────┐
│ runPrompts()      form() chain - unchanged               │
│ runProcessors()   sorted by each handler processWeight() │
│ runPostBuild()    every handler, none hard-coded         │
│ progress denom.   countPrompts() reads the chain         │
└──────────────────────────────────────────────────────────┘
      adding a handler = the chain, plus a weight, or no compile

Changes

  • HandlerInterface::processWeight(): int: declared with no AbstractHandler default, so a new handler does not compile until it states where it processes. This is the part that takes the ordering out of the "invisible to the type system" category the issue describes.
  • All 41 handlers: each declares processWeight(), reproducing the previous processing order exactly, in steps of ten from Dotenv at 10 to Internal at 410.
  • PromptManager::runProcessors(): iterates getProcessHandlers() instead of a 41-entry $ids array.
  • PromptManager::runPostBuild(): asks every handler, in the reverse of the processing order so HostingProvider still reports before CiProvider. Handlers with nothing to report already return NULL from AbstractHandler::postBuild(), so the output is unchanged and the dead Starter entry is gone.
  • TOTAL_RESPONSES replaced by countPrompts(): the constant becomes a $totalResponses property filled from the built form, where the named steps are the prompts and the steps added by intro() are not.
  • Docs: .vortex/CLAUDE.md and .vortex/installer/CLAUDE.md drop the removed constant from the video-regeneration triggers, and the installer guide gains an "Ordering" subsection stating that runPrompts() is the catalogue and processWeight() is the processing order.

Not changed

The installer produces byte-identical output. ahoy update-snapshots reports Total: 154 | Succeeded: 154 | Updated: 0 on a first run, with no fixture regenerated, which is the evidence that the derived processing order reproduces the hand-written one exactly.

The processing order is genuinely not the reverse of the prompt order, despite the comment that used to say so: NotificationChannels, HostingProjectName, Modules, the Org/MachineName pair and most of the Drupal-section tail sit in positions a straight reversal does not produce. The weights reproduce the existing order rather than "correcting" it, so no installed file moves.

Tests

  • New tests/Unit/Prompts/PromptManagerTest.php: every registered handler appears in the processing order exactly once, the weights are unique so the order is deterministic, and the anchors hold: Dotenv first, Webroot second because it renames the web root directory that later handlers write into, Internal last.
  • AbstractHandlerTypeTest was missing CustomModules from its data provider, covering 38 of the 39 prompt handlers; added.

Known limitation

The denominator counts conditional prompts too, so a run that skips them finishes below its own total: the re-recorded demo ends at (34/39). Whether a conditional prompt runs depends on answers the run has not collected when the first label renders, and a denominator that changed mid-run would read worse than a stable maximum. The previous constant was not derived from anything at all, and sat below the 39 prompts the chain defines.

Installer video

Re-recorded with ahoy update-videos installer, which doubles as an end-to-end check that the prompt flow is unaffected: the expect script drove all 34 prompts of the demo path with no mismatch, and the pipeline's own gate passed with No errors, warnings or failures recorded in 'installer'. installer.png came out byte-identical, so the poster frame is unchanged; only installer.json and installer.svg moved.

Comparing the visible text of the old and new SVG, every difference attributable to this change is (N/36) becoming (N/39) across counters 1 to 34. The re-recording also picks up drift that predates this branch: the old recording had no Fast 404 entry in the modules list, so it was already stale against main.

Follow-ups

  • countPrompts() reads FormBuilder::$steps through reflection because laravel/prompts exposes no accessor for it. That is the only way to count the prompts from the chain itself rather than from a second list; happy to swap it for a patch adding a getter, or for a counter threaded through the chain, if either reads better.
  • getResponsesSummary() is still a hand-written list of every handler with its own labels and conditional rows, which is why the handler imports remain in PromptManager.
  • HandlerInterface::postInstall() is implemented by Internal but has no caller anywhere, so its "add and commit all files" output is never printed; left alone because wiring it would change installer output.

Screenshots

N/A

Summary by CodeRabbit

  • Refactor

    • Handler processing order is now derived from the handlers themselves rather than a maintained list, so adding or removing a handler no longer requires a coordinated edit elsewhere.
    • Post-build messages are collected from every handler instead of a fixed set.
    • The prompt progress total is counted from the prompt chain instead of a hard-coded constant.
  • Documentation

    • Updated guidance on handler ordering and on when the installer walkthrough video needs re-recording.

Installer prompt ordering and progress totals now derive from handler metadata and form contents, but resolved prompts can display an incorrect subsequent progress position and the committed installer demo still shows the old prompt total. Address these bounded installer-flow and documentation artifacts before merge.

750-761: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Advance progress for resolved form steps.

When a handler resolves here, prompt() does not run. args() then does not call label(), so currentResponseIndex is not incremented. countPrompts() still includes the named step. The next interactive prompt shows a progress index below the completed form-step count.

Increment currentResponseIndex when this method accepts a resolved value.
