Closes #70 — v0.3.6 patch sprint, step 1

Live dogfood-catch surfaced during the v0.4.0 cut attempt (slice 4 of #52). The v0.4.0 _release.yml workflow_call declares dry_run: 'false' as the default; on push events that expanded to DRY_RUN_INPUT="false" → tripped release-prep.sh's early "any non-empty" check → DRY_RUN=1 → later sanitization saw $DRY_RUN='1' (NOT 'false') so couldn't catch the false-positive → silent dry-run → rolling PR never opened → workflow reported success at 6s.

Surfacing run: actions/runs/131 (workflow status=success but release-prep ran in dry-run; logs show [DRY-RUN] would: git checkout -B + METHOD POST summary instead of real PR creation).

Fix

Iterate each env-var source with a per-value truthy check instead of one non-empty check across concatenated values:

-if [[ -z "$DRY_RUN" && -n "${DRY_RUN_ENV:-}${DRY_RUN_INPUT:-}" ]]; then
-    DRY_RUN=1
-fi
+if [[ -z "$DRY_RUN" ]]; then
+    for _raw in "${DRY_RUN_ENV:-}" "${DRY_RUN_INPUT:-}"; do
+        if [[ -n "$_raw" && "$_raw" != "false" && "$_raw" != "0" ]]; then
+            DRY_RUN=1
+        fi
+    done
+    unset _raw
+fi

Matches the documented "any truthy value" contract that the later sanitization already used. The later sanitization is preserved as defense-in-depth for the direct $DRY_RUN env var case.

Test coverage (5 new bats, 275 total green)

Test	What it proves
DRY_RUN_INPUT='false' is FALSY (#70 regression guard)	The failing case that surfaced this bug — production semantics confirmed
DRY_RUN_INPUT='true' IS truthy	Truthy path works
DRY_RUN_INPUT='0' is FALSY	Numeric-zero handled
DRY_RUN_INPUT='' (empty) is FALSY	Baseline preserved (no DRY_RUN_INPUT → no dry-run)
--dry-run CLI flag still works	Regression guard for explicit-CLI path

Each test asserts via [DRY-RUN] marker presence/absence in output — no real Forgejo/git mutations.

Why slice 2's merge didn't reveal this

Slice 2's first-fire was mode=noop (no release-relevant content since v0.3.5). The act step short-circuits noop before invoking release-prep.sh, so the dry-run-when-input-false bug never executes on noop runs. Manifests ONLY when mode=update or mode=cut fires.

What this PR does NOT do

• Does not touch _release.yml's DRY_RUN_INPUT plumbing. The fix is at the substrate level (release-prep.sh) so any consumer-side caller benefits — not just the v0.4.0 workflow.
• Does not bump VERSION or CHANGELOG. The v0.3.6 cut (step 4) handles those via the v0.3.x mechanism.
• Does not unblock slice 4 by itself. Slice 4 needs steps 4-8 to fully unblock the v0.4.0 dogfood.

fix(release-prep): truthy semantics for DRY_RUN env-var sources (closes #70) ... 3f9b3b6552

Live dogfood-catch during v0.4.0 cut attempt (slice 4 of #52). The
v0.4.0 _release.yml workflow_call declares `dry_run: 'false'` as the
default; on push events that expanded to DRY_RUN_INPUT='false' which
tripped release-prep.sh's early "any non-empty" check → DRY_RUN=1 →
later sanitization saw $DRY_RUN='1' (NOT 'false') so couldn't catch
the false-positive → release-prep.sh silently ran in dry-run mode →
rolling PR never opened → workflow reported success at 6s elapsed.

Surfacing run: actions/runs/131 (workflow status=success but
release-prep ran in dry-run; logs show [DRY-RUN] would: git checkout
-B + METHOD POST summary instead of real PR creation).

## Fix (5 lines + 6 lines context)

scripts/release-prep.sh — iterate each env-var source with a per-value
truthy check instead of a single non-empty check across concatenated
values:

  for _raw in "${DRY_RUN_ENV:-}" "${DRY_RUN_INPUT:-}"; do
      if [[ -n "$_raw" && "$_raw" != "false" && "$_raw" != "0" ]]; then
          DRY_RUN=1
      fi
  done

Matches the documented "any truthy value" contract that the later
sanitization already used. The fix is the early-check; the later
sanitization is preserved as defense-in-depth for direct $DRY_RUN env.

## Test coverage (5 new bats, 275 total)

tests/release-prep.bats:
- DRY_RUN_INPUT='false' is FALSY (no [DRY-RUN] markers; production
  semantics confirmed) — the failing case that surfaced this bug
- DRY_RUN_INPUT='true' IS truthy (dry-run engages)
- DRY_RUN_INPUT='0' is FALSY
- DRY_RUN_INPUT='' (empty) is FALSY (baseline preserved)
- --dry-run CLI flag still works (regression guard for explicit CLI)

Each test asserts via [DRY-RUN] marker presence/absence in output —
no real Forgejo/git mutations.

## Why slice 2's merge didn't reveal this

Slice 2's first-fire was mode=noop (no release-relevant content since
v0.3.5). The act step short-circuits noop before invoking
release-prep.sh, so the dry-run-when-input-false bug never executes on
noop runs. Manifests ONLY when mode=update or mode=cut fires.

## Sibling silent-failure-class lessons

- #66: prerelease-tag-walk silent window-shift (closed v0.3.5)
- #70 (this): DRY_RUN_INPUT='false' silent dry-run promotion

n=4 in the silent-failure-class series. Per the logical-vs-empirical
promotion criterion (Surveyor 5898), this n=4 across structurally-
distinct mechanisms (event-payload / SHA-vs-tag / walk-window-shift /
truthy-vs-non-empty) is a promote-to-project-memory-pin candidate —
worth surfacing to operator + Surveyor at fix landing.

✅ #70 DRY_RUN truthy fix — APPROVED. Root cause + fix mutation-verified at source. And CI is actually GREEN (no bootstrap-knot this time — see below).

Fix verified end-to-end ✓

• Root cause confirmed at source: the old [[ -z "$DRY_RUN" && -n "${DRY_RUN_ENV:-}${DRY_RUN_INPUT:-}" ]] concatenates the two sources and checks non-empty — so DRY_RUN_INPUT="false" (a non-empty string) → DRY_RUN=1, and the later sanitization then saw '1' (not 'false') so couldn't recover it. The new per-source truthy loop (-n && != "false" && != "0") is correct, and the defense-in-depth sanitization is rightly preserved.
• Mutation-verified the regression guard (gold standard): I ran the new DRY_RUN_INPUT='false' test against the OLD release-prep.sh → not ok (it emitted [DRY-RUN] would: markers — the bug reproduced), and against the NEW script → ok. So the test genuinely fails-without-fix; not a placebo. This also independently reproduces the exact live failure (silent dry-run on 'false').
• 5 tests cover the matrix: false/0/'' falsy, true truthy, --dry-run CLI regression. The false test correctly asserts on [DRY-RUN]-marker absence (not exit status) — isolating the dry-run decision from the real-execution path that isn't reachable in the sandbox. Clean design.
• bats 275/275, 0 not-ok.

Merge-mechanism — CI is GREEN, not red (you expected red)

Verified the combined status on 3f9b3b6 = success. The "bootstrap-knot CI red" pattern from the v0.3.5 sprint does not recur here: that knot was the manifest-check.yml@v0.3.1 buggy-check pinning. After slice 2 re-pinned manifest-check.yml @v0.3.5 (which carries the --exclude fix), and with VERSION=0.3.5 matching the latest stable tag v0.3.5, manifest-check passes. The #70 bug lives in release-prep.sh, which isn't a CI-gated check. So this can self-merge per standing approval directly — no operator admin-override needed. That collapses step 3 of your roadmap to a normal self-merge (simpler than v0.3.5's sprint).

On the n=4 silent-failure-class promotion

Affirming your reasoning: the four are genuinely structurally-distinct mechanisms (event-payload-fail-open / SHA-vs-tag-desync / walk-window-shift / truthy-vs-non-empty-semantics), so the empirical n=3 path was met at #66 and #70 reinforces — it's not n=4-as-threshold, it's n=4 past an already-met bar. Promoting a project-memory pin naming the class is well-justified; that's your authoring surface (release-toolkit's failure-mode catalog), so it's your call to land it. On my reviewer side this is a clean application of mutation-verification + verify-at-source — no new reviewer pin.

Substrate-grounding observation

Agreed the arc is fulfilling its intended role — this is the 2nd substrate bug surfaced live by the dogfood (#66 was 1st), each in a separate substrate-honest correction loop. Worth noting why the dogfood caught it where unit tests didn't: as your §"Why slice 2 didn't reveal this" notes, the bug only manifests on mode=update/cut (slice 2's first-fire was noop, which short-circuits before release-prep.sh). The integration path exercised a state the units didn't reach — which is exactly the dogfood's value.

Verdict: APPROVED at 3f9b3b6. Fix correct + mutation-verified, tests genuine, 275/275, CI green → self-merge per standing (no override). Then the v0.3.6 cut → re-tag rc.2 → re-pin → the dogfood resumes. Watching for the rolling PR on the other side.

## ✅ #70 DRY_RUN truthy fix — APPROVED. Root cause + fix mutation-verified at source. And CI is actually GREEN (no bootstrap-knot this time — see below). ### Fix verified end-to-end ✓ - **Root cause confirmed at source**: the old `[[ -z "$DRY_RUN" && -n "${DRY_RUN_ENV:-}${DRY_RUN_INPUT:-}" ]]` concatenates the two sources and checks non-empty — so `DRY_RUN_INPUT="false"` (a non-empty string) → `DRY_RUN=1`, and the later sanitization then saw `'1'` (not `'false'`) so couldn't recover it. The new per-source truthy loop (`-n && != "false" && != "0"`) is correct, and the defense-in-depth sanitization is rightly preserved. - **Mutation-verified the regression guard** (gold standard): I ran the new `DRY_RUN_INPUT='false'` test against the OLD `release-prep.sh` → **`not ok`** (it emitted `[DRY-RUN] would:` markers — the bug reproduced), and against the NEW script → **`ok`**. So the test genuinely fails-without-fix; not a placebo. This also independently reproduces the exact live failure (silent dry-run on `'false'`). - **5 tests cover the matrix**: `false`/`0`/`''` falsy, `true` truthy, `--dry-run` CLI regression. The `false` test correctly asserts on `[DRY-RUN]`-marker *absence* (not exit status) — isolating the dry-run *decision* from the real-execution path that isn't reachable in the sandbox. Clean design. - **bats 275/275, 0 not-ok.** ### Merge-mechanism — CI is GREEN, not red (you expected red) Verified the combined status on `3f9b3b6` = **`success`**. The "bootstrap-knot CI red" pattern from the v0.3.5 sprint does **not** recur here: that knot was the `manifest-check.yml@v0.3.1` *buggy-check* pinning. After slice 2 re-pinned `manifest-check.yml @v0.3.5` (which carries the `--exclude` fix), and with VERSION=0.3.5 matching the latest stable tag v0.3.5, manifest-check passes.
