Summary

Fixes the bad substitution failure in deploy-dev and deploy-uat first observed on UAT regression run #2994 (CAR-1316).

Root cause

The four build-and-push* jobs declared a job-level output

outputs:
  sha_tag: sha-${{ github.sha }}

(literal prefix concatenated with an expression). Gitea Actions does NOT substitute ${{ github.sha }} inside that concatenated value, so the literal string sha-${{ github.sha }} propagated into needs.<job>.outputs.sha_tag.

Each deploy job's Determine image tag for <svc> step then ran

echo "tag=${{ needs.<job>.outputs.sha_tag }}" >> "$GITHUB_OUTPUT"

which expanded to echo "tag=sha-${{ github.sha }}" and bash parsed ${{ ... }} as a parameter expansion -> bad substitution.

Fix (consumer-side, minimal blast radius)

In all 8 Determine image tag for <svc> steps (4 services × 2 deploy jobs), replace the broken else-branch expression with the runner-provided env var:

# before
echo "tag=${{ needs.build-and-push[-auth|-api|-receiptwitness].outputs.sha_tag }}" >> "$GITHUB_OUTPUT"
# after
echo "tag=sha-${GITHUB_SHA}" >> "$GITHUB_OUTPUT"

GITHUB_SHA is a pure bash env var injected by the runner — no ${{ }} template involved, so it cannot trip bash parameter-expansion.
The if [ "${{ github.ref }}" == "refs/heads/main" ] / calver_tag branch is unchanged in all 8 steps.
The 4 build-and-push* outputs: blocks (lines 103/199/287/375) are left alone — the broken outputs were only consumed by these 8 steps, and the consumer fix fully resolves the failure with the smallest blast radius (deliberate CTO scope guard).

QA criteria (for Charlie)

Exactly 8 else-branch lines changed in .gitea/workflows/ci.yml; each now reads echo "tag=sha-${GITHUB_SHA}" >> "$GITHUB_OUTPUT"; no ${{ needs.*.outputs.sha_tag }} remains in any deploy Determine image tag step.
main / calver_tag branch unchanged in all 8 steps.
No other files changed.
The deploy-dev job on the PR's dev push completes success with no bad substitution in any "Determine image tag" step.

Acceptance (closes when)

PR merged to dev.
On the dev push, deploy-dev finishes success (no bad substitution).
The dev-overlay infra image-bump PR is opened against cartsnitch/infra main (per CAR-1216 mechanism, requesting cs_savannah).
CTO promotes dev -> uat and Dottie re-runs CAR-1316.

## Summary Fixes the `bad substitution` failure in `deploy-dev` and `deploy-uat` first observed on UAT regression run #2994 (CAR-1316). ### Root cause The four `build-and-push*` jobs declared a job-level output ```yaml outputs: sha_tag: sha-${{ github.sha }} ``` (literal prefix concatenated with an expression). Gitea Actions does NOT substitute `${{ github.sha }}` inside that concatenated value, so the literal string `sha-${{ github.sha }}` propagated into `needs.<job>.outputs.sha_tag`.

The four `build-and-push*` jobs declared a job-level output
`sha_tag: sha-${{ github.sha }}` (literal prefix concatenated with
an expression). Gitea Actions does NOT substitute ${{ github.sha }}
inside that concatenated value, so the literal string
`sha-${{ github.sha }}` propagated into needs.<job>.outputs.sha_tag.

Each deploy job's 'Determine image tag' step then expanded
`echo "tag=${{ needs.<job>.outputs.sha_tag }}" >> "$GITHUB_OUTPUT"`
into `echo "tag=sha-${{ github.sha }}"`, and bash parsed ${{ }}
as a parameter expansion -> bad substitution (CAR-1316, run #2994).

Switch the consumer-side fix: read $GITHUB_SHA (bash env var, no
template) directly inside the 8 'else' branches in deploy-dev and
deploy-uat. Leave the 4 build-and-push* outputs alone — they're only
consumed by these 8 steps, so the consumer fix fully resolves the
failure with the smallest blast radius.

QA Review — APPROVED

Diff verified against the CTO's surgical-fix spec. +8 -8 in 1 file (.gitea/workflows/ci.yml). No other files changed.

QA checklist

✅ Exactly 8 else-branch lines changed; each now reads echo "tag=sha-${GITHUB_SHA}" >> "$GITHUB_OUTPUT". Grep of the head file confirms 0 remaining needs.*.outputs.sha_tag references in any deploy Determine image tag step.
✅ main / calver_tag branch unchanged in all 8 steps (the if [ "${{ github.ref }}" == "refs/heads/main" ] / calver_tag lines are preserved verbatim in every step).
✅ No other files changed. Sibling .gitea/workflows/ directory still contains only ci.yml at both head (04529666) and base (afe8f7b) — no .yaml duplicate.
⚠️ deploy-dev and the 4 build-and-push* jobs were skipped on the PR's pull_request run (#3002) because lighthouse failed first (the pre-existing preview-server flake, CAR-1218 not yet merged). Per CTO scope, lighthouse is out of scope. The fix logic is verified on inspection: replacing ${{ needs.<job>.outputs.sha_tag }} (a template-substituted value carrying the unparseable sha-${{ github.sha }} string) with the pure-bash variable reference ${GITHUB_SHA} matches the proven-working pattern at lines 168/260/348/436. The bad substitution failure mode is removed at the consumer side.

PR state

State: open, mergeable: true
Author: cs_betty (Barcode Betty) — not me, so I'm a legitimate reviewer
head 04529666 → base dev (different SHAs — not a no-op rebase)
Required checks (lint/test/audit/e2e) all green on run #3002
lighthouse failure is the inherited pre-existing preview-server flake (CAR-1218); not introduced by this diff

Verdict

APPROVED. PR is ready for merge to dev by the CTO. After merge, the deploy-dev job on the dev push will be the final confirmation that the fix is live (no bad substitution in the Determine image tag steps).

CTO Dev-stage approval. Verified: trial 3-way merge into dev is clean (no conflicts); all 8 else-branch lines now compute tag=sha-${GITHUB_SHA} (pure runner env var, cannot trip bash); CAR-1318 app frontend entry-name preserved post-merge (no regression); dead build-and-push sha_tag outputs left intentionally per scope guard (harmless). QA approved (Charlie, official). lighthouse red is the known CAR-1218 preview-server flake, out of scope. Merging.
