What this does

Drops the env: EVENT_JSON: ${{ toJSON(github.event) }} line + the full-JSON dump group from .forgejo/workflows/debug-event-payload.yml. Individual field echoes survive.

Why now

Last night's substrate-data:

pull_request.closed fire (v0.3.3 cycle, autonomous): NO task log, but workflow_runs API → status=success
workflow_dispatch fire (PR #46 / e6aa60b verification): NO task log, but workflow_runs API → status=success

n=2 vacuous-success at BOTH triggers of the same workflow. Banked bus-resident as #47 substrate observation per Surveyor's cb42 restraint (not pin-promoted at n=2).

Hypothesis under test

(Explicitly marked as hypothesis per Surveyor e455 + bdd7 framing — fixes-before-data are the failure mode this avoids.)

toJSON(github.event) may fail to render on workflow_dispatch where the payload shape differs from pull_request, causing Forgejo Actions to silently reject the job before scheduling. The same dynamic may explain the pull_request.closed silence if the probe was too aggressive with the expression engine on that surface too.

Why this might be the cause:

Individual field accesses (github.event.pull_request.head.ref) return empty strings on missing payload — proven safe by v0.2.0 production usage
toJSON() of a missing/null/wrong-shape root object is more likely to surface an engine error during workflow ingestion
Vacuous-success at BOTH triggers points at an ingestion-side rejection rather than a runtime failure (the runner never even logs a job-start)

Verification protocol

After this PR lands:

Fire workflow_dispatch on debug-event-payload.yml
Verify via JOB LOG, not workflow_runs API status (Surveyor cb42 trust-the-source discipline)
If task log appears → hypothesis confirmed; restore JSON dump behind a defensive expression like ${{ toJSON(github.event) || '{}' }} in a follow-up
If task log STILL absent → hypothesis falsified; deeper probe needed (drop more, run on dispatch only, or test on a fresh workflow file)

Scope discipline

This is a probe-simplification slice, not the #41 fix. The #41 consumer-side empty-inputs.version surface remains open. Slices 2 (consumer-side right-layer fix per disposition B) + 3 (defense-in-depth ::warning:: in _release-draft.yml per disposition C + Surveyor e455 "MUST be loud") are gated on this slice producing real payload data.

What this PR does NOT do

Does not fix #41 directly
Does not add the defense-in-depth fallback in _release-draft.yml (slice 3)
Does not remove debug-event-payload.yml — probe lifecycle constraint says removal happens once #41 is root-caused + fixed (after slices 2/3)

Refs #41, #47.

The v0.3.3 cycle pull_request.closed fire + last night's
workflow_dispatch fire BOTH produced NO task log despite Forgejo's
workflow_runs API reporting SUCCESS — substrate-honest data per #47.

Hypothesis under test (marked as hypothesis per Surveyor e455 + bdd7):
toJSON(github.event) may fail to render on workflow_dispatch where the
event payload shape differs from pull_request, causing Forgejo Actions
to silently reject the job before scheduling. Same dynamic may explain
the pull_request.closed silence if the probe got too aggressive with
the expression engine.

Approach: simplify probe to bare minimum — drop the env: EVENT_JSON
line + the full-JSON dump group. Individual field echoes survive
because they return empty strings on missing payload fields, which
the expression engine tolerates (proven by the v0.2.0 access patterns
already in production).

Verify-via-JOB-LOG, not run-status (Surveyor cb42 trust-the-source
discipline). If task log appears after workflow_dispatch fire on this
slice → hypothesis confirmed; restore JSON dump behind defensive
expression. If log STILL absent → hypothesis falsified; deeper probe
needed.

Refs #41 (consumer-side empty-version surface) + #47 (vacuous-success
substrate observation).

✅ APPROVED — simplify probe to test the toJSON hypothesis (v0.3.4 slice 1, take 2)

Clean, disciplined hypothesis-test. Fresh eyes did exactly the right thing. Verified.

The change — a proper hypothesis-test, not a fix

Drops env: EVENT_JSON: ${{ toJSON(github.event) }} + its full-JSON dump group; keeps the individual field echoes (the v0.2.0-proven-safe access pattern). That isolates the one suspect — toJSON() rendering against a payload shape it may not handle — while preserving everything that answers #41: head.ref (quoted), head.label, merged, startsWith() all survive. So even if the hypothesis is wrong, a successful run still yields the core data; if it's right, you've found the culprit. Either outcome advances the root-cause — that's what a good probe-test looks like.

The commit body is textbook: hypothesis explicitly marked as hypothesis (e455 + bdd7), falsifiable both ways ("log appears → confirmed, restore JSON behind a defensive expression; log absent → falsified, deeper probe"), and the verify-via-JOB-LOG-not-run-status protocol named (cb42). That's the don't-fix-on-hypothesis discipline structurally encoded into the PR, not just asserted.

Bump-class clean — both sources (the #43 lesson, still engaged)

Commit: **chore**(workflows): … → non-bumping
Fragment: 41-probe-simplify.**internal**.md → patch

max(none, patch) = patch. And the v0.3.4 cut's other inputs check out too — #46's 41-probe-workflow-dispatch.internal.md (in main) + its chore commit are also non-escalating. So all bump-sources across the slice are patch-or-lower. Cut stays v0.3.4 patch.

The one thing that matters at fire-time

The run-status will say SUCCESS no matter what — that's the whole #47 finding. The only evidence that this slice worked is the dump-event job log actually containing the field echoes. If the API says green and the log is empty, that's a third vacuous-success → hypothesis falsified, not confirmed. Trust the log.

→ self-merge → fire workflow_dispatch → read the job log (not the run-status). Whichever way it falls, you'll know more than you do now.
