Fix | Minimum Speaker Requirement not Enforced

Summary of Changes

Problem

The speaker validation on the presentation speakers form only checked that at least one speaker existed, ignoring the min_speakers and max_speakers constraints configured on the event type. The Review step's Complete action ran no speaker validation at all, so a presentation missing its required speaker count or mandatory moderator could be finalized from there.

Changes

src/components/presentation-submit-validation/index.js (new)

Shared validation module — single source of truth for the pre-submit check, used by both the Speakers step (Save) and the Review step (Complete):

• getSpeakerLimits(type) — returns { min, max } from the event type, clamping max up to min when the type is misconfigured with max < min.
• getSpeakerCountErrorField(count, min, max) — selects the error key: remove_speakers (over the max), add_only_one_speaker (min = max = 1), add_exact_number_of_speakers (min = max > 1), add_speakers (bounded range).
• validateSpeakerCount(entity) — validates the speaker count against min/max when the type uses speakers; tolerates a missing speakers array.
• getSubmitValidationError(entity, selectionPlanSettings) — mandatory-moderator check first (preserving the original validation order), then speaker count; returns the error key plus i18n params built from the tenant-configurable labels.

src/components/presentation-speakers-form.js

• handleSubmit now delegates to getSubmitValidationError instead of the boolean at-least-one check.
• The add-speaker capacity (canAddSpeakers) is derived from the same entity.type limits the validation uses (previously summit.event_types), so UI capacity and validation can no longer disagree.
• The missing_speaker error now uses the tenant-configurable speaker label.
• Guards added for a missing/null entity.speakers array (render and CPFSpeakerInput prop).
• Removed unused getMarketingValue import.

src/components/presentation-review-form.js

• The Complete action now runs the same getSubmitValidationError check before submitting and shows the validation error in a modal — closing the bypass where a presentation could be finalized without meeting the speaker/moderator requirements.

src/components/presentation-submit-validation/__tests__/presentation-submit-validation.test.js (new)

• 19 unit tests covering limit clamping, error-key selection, count validation (null speakers array, over-max with excess), and the combined submit check (moderator-before-speakers ordering, blocked and valid cases), asserting the rendered English messages.
• Run with npx jest src/components/presentation-submit-validation (full suite: npx jest).

src/i18n/en.json

• Replaced the single add_speaker error key with granular keys: add_speakers, add_only_one_speaker, add_exact_number_of_speakers, remove_speakers.
• missing_speaker now accepts a {speaker} parameter.

Summary by CodeRabbit

• New Features

Pull request overview

This PR updates the presentation speakers form validation to enforce event-type min_speakers/max_speakers constraints and aligns i18n error messaging (including tenant-configurable speaker labels) with the new validation paths.

Changes:

• Enforced min/max speaker constraints during submit with more specific, constraint-aware validation errors.
• Updated missing_speaker to use the tenant-configurable {speaker} label.
• Expanded i18n error keys/messages in en.json and added corresponding errors translations in zh.json.

src/components/presentation-speakers-form.js:256

• entity.speakers is now treated as possibly undefined (entity.speakers?.map / Array.isArray), but it’s still passed through to CPFSpeakerInput as-is. CPFSpeakerInput assumes speakers is an array (speakers.length), so passing undefined will throw during option filtering. Default to an empty array here.

                                <CPFSpeakerInput
                                    id="speaker"

📝 Walkthrough

Walkthrough

The presentation speaker form now derives configured speaker limits, validates moderator and speaker requirements, uses differentiated localized errors, applies configurable labels, and safely handles missing speaker arrays during rendering.

Changes

Speaker validation

Layer / File(s)	Summary
Speaker limits and submission validation src/components/presentation-speakers-form.js, src/i18n/en.json	The form derives minimum and maximum speaker limits, validates moderator presence and speaker counts, protects invalid limits, and displays differentiated localized errors.
Speaker form interaction and rendering src/components/presentation-speakers-form.js	The form uses computed capacity and configurable labels, preserves speaker selection and addition behavior, and safely renders absent speaker arrays.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Mergeability Score: 🟡 Moderate · up to 47394

The speaker form may enforce one event limit while displaying another, which can prevent users from adding the required number of speakers or expose inconsistent capacity behavior. Aligning both paths to the same event-type configuration is needed before merge.

@tomrndom validateSpeakerCount enforces min_speakers unconditionally, but the backend only enforces the minimum when are_speakers_mandatory is set — so this check blocks submissions the API accepts.

Concrete failure: an event type with use_speakers = true, are_speakers_mandatory = false, min_speakers = 2. A submitter with 1 speaker can no longer finish — Save on the Speakers step and Complete on the Review step both refuse — while PresentationService::completePresentation would accept that presentation, because Presentation::fulfilSpeakersConditions() gates the min check on the mandatory flag (summit-api app/Models/Foundation/Summit/Events/Presentations/Presentation.php:1339):

if ($type->isAreSpeakersMandatory() && $min > $count) return false;
if ($count > $max) return false;

That config is reachable: summit-admin exposes the checkbox and the min/max fields as independent inputs (event-type-dialog.js), with the checkbox defaulting to false. The code this PR replaces also respected the flag (!entity.type.are_speakers_mandatory || ...), and the ticket's Panel type (OCP EMEA 2026, type id 973) has are_speakers_mandatory: true — so mirroring the backend still fully fixes the reported bug while removing the divergence.

Suggested fix — apply the min only when the flag is set; the max stays unconditional, same as the backend:

const minRequired = entity.type.are_speakers_mandatory ? min : 0;
if (speakersCount <= max && speakersCount >= minRequired) return { valid: true };

And pin the flag semantics in __tests__/presentation-submit-validation.test.js:

it('does not enforce the minimum when speakers are not mandatory, mirroring fulfilSpeakersConditions()', () => {
    const entity = {
        type: { use_speakers: true, are_speakers_mandatory: false, min_speakers: 2, max_speakers: 5 },
        speakers: [{ id: 1 }]
    };
    expect(validateSpeakerCount(entity)).toEqual({ valid: true });
});

it('still enforces the maximum when speakers are not mandatory', () => {
    const entity = {
        type: { use_speakers: true, are_speakers_mandatory: false, min_speakers: 0, max_speakers: 2 },
        speakers: [{ id: 1 }, { id: 2 }, { id: 3 }]
    };
    const result = validateSpeakerCount(entity);
    expect(result.valid).toBe(false);
    expect(result.errorField).toBe('remove_speakers');
});

Note: the existing fixtures that exercise the below-min branch don't set the flag, so they'll need are_speakers_mandatory: true added to their type objects after this change — "is invalid when exactly one speaker is required and none were added", "is invalid when the entity has no speakers array at all", and "blocks submission when the speaker count is below the minimum". The over-max and moderator-ordering tests are unaffected.
