TINY orthogonal cleanup, preserved from the closed SCAFFOLD #2855 per the PM reconcile (1bcb2e75 keystone-structure call). #2845 (acbc0da9) was MERGED with the full template-asset channel + tests, but the cfg.ConfigFiles init repetition at the two inject sites in workspace_provision.go was NOT touched by #2845.

The repetition (pre-fix, both sites identical 4-line ceremony):

if cfg.ConfigFiles == nil {
    cfg.ConfigFiles = make(map[string][]byte)
}
cfg.ConfigFiles[".auth_token"] = []byte(token)             // site 1 (line 425-428)
cfg.ConfigFiles[".platform_inbound_secret"] = []byte(secret) // site 2 (line 475-478)

The de-dup (post-fix, extracted to ensureConfigFiles helper):

ensureConfigFiles(cfg)[".auth_token"] = []byte(token)
ensureConfigFiles(cfg)[".platform_inbound_secret"] = []byte(secret)

Behavior-preserving: the helper allocates on demand (same if nil { make } ceremony), returns the SAME map (writes through the returned pointer are visible via cfg.ConfigFiles). The mapsSamePointer sentinel-write trick in the test pins this contract — a future regression that returns a copy would fail the test.

New tests (2):

• TestEnsureConfigFiles_AllocatesWhenNil: nil ConfigFiles → helper allocates + returns the SAME map. Sentinel-write verifies the same-map identity.
• TestEnsureConfigFiles_ReusesWhenNonNil: non-nil ConfigFiles → helper returns the SAME map (no copy). Pre-populated entries preserved.

The existing TestIssueAndInjectToken_NilConfigFilesAllocated already pins the end-to-end nil-alloc behavior via the public API (this PR doesn't change that test, just adds the more focused unit tests on the helper itself).

Local validation:

• go test ./internal/handlers/ — clean (25.8s, all existing pass + 2 new helper tests pass)
• go test ./internal/provisioner/ — clean (0.09s, no regressions)
• go vet + go build — clean

Auth pattern honored: all Gitea API calls used ${GIT_HTTP_PASSWORD} / ${GITEA_ISSUE_TOKEN} env vars in -H headers (no curl -u).

Refs #24 (RFC #2843). Diff stat: 2 files, +96 / -6.

fix(handlers): de-dup cfg.ConfigFiles init across inject sites (tiny) ... 842f07f879

TINY orthogonal cleanup, preserved from the closed SCAFFOLD
#2855 per the PM reconcile (1bcb2e75 keystone-structure call).
#2845 (acbc0da9) was MERGED with the full template-asset channel
+ tests, but the cfg.ConfigFiles init repetition at the two
inject sites in workspace_provision.go was NOT touched by #2845.

THE REPETITION (pre-fix, both sites identical 4-line ceremony):
  if cfg.ConfigFiles == nil {
      cfg.ConfigFiles = make(map[string][]byte)
  }
  cfg.ConfigFiles[.auth_token] = []byte(token)        // site 1 (line 425-428)
  cfg.ConfigFiles[.platform_inbound_secret] = []byte(secret) // site 2 (line 475-478)

THE DE-DUP (post-fix, extracted to ensureConfigFiles helper):
  ensureConfigFiles(cfg)[.auth_token] = []byte(token)
  ensureConfigFiles(cfg)[.platform_inbound_secret] = []byte(secret)

Behavior-preserving: the helper allocates on demand (same
'if nil { make }' ceremony), returns the SAME map (writes
through the returned pointer are visible via cfg.ConfigFiles).
The mapsSamePointer sentinel-write trick in the test pin this
contract — a future regression that returns a copy would fail
the test.

NEW TESTS (2):
- TestEnsureConfigFiles_AllocatesWhenNil: nil ConfigFiles →
  helper allocates + returns the SAME map. Sentinel-write verifies
  the same-map identity.
- TestEnsureConfigFiles_ReusesWhenNonNil: non-nil ConfigFiles →
  helper returns the SAME map (no copy). Pre-populated entries
  preserved.

The existing TestIssueAndInjectToken_NilConfigFilesAllocated
already pins the end-to-end nil-alloc behavior via the public
API (this PR doesn't change that test, just adds the more
focused unit tests on the helper itself).

LOCAL VALIDATION:
- go test ./internal/handlers/  -> clean (25.8s, all existing
  pass + 2 new helper tests pass)
- go test ./internal/provisioner/ -> clean (0.09s, no regressions)
- go vet ./...                   -> clean
- go build ./...                 -> clean

APPROVED: I reviewed molecule-core #2856 at head 842f07f879.

This is behavior-preserving. The two injection sites still write the same keys (.auth_token and .platform_inbound_secret) into cfg.ConfigFiles; the repeated nil-check/make ceremony is just extracted into ensureConfigFiles(cfg). The helper preserves the old semantics: allocate only when nil, return the same map stored on the config, and reuse an existing map without copying or clobbering caller entries.

The new tests are load-bearing for the extraction: TestEnsureConfigFiles_AllocatesWhenNil proves nil allocation and write visibility through cfg.ConfigFiles; TestEnsureConfigFiles_ReusesWhenNonNil proves the already-populated map is reused. The mapsSamePointer sentinel is a reasonable way to assert shared map state for this contract.

5-axis: correctness/robustness are covered by unchanged call-site behavior and focused tests; security surface is unchanged (same token/secret writes as before); performance is unchanged except avoiding duplicate ceremony; readability improves by removing duplicated map initialization.

Exact-head CI is green on 842f07f8: all-required, Platform Go, E2E API Smoke, Handlers Postgres, Peer Visibility, Shellcheck, and relevant canvas/chat no-op lanes all succeeded.

APPROVE on 842f07f879.

Reviewed the tiny ensureConfigFiles extraction: both production callers still write the same .auth_token and .platform_inbound_secret entries through the same ConfigFiles map, with nil allocation centralized and no clobber when the map is already present. The new tests are load-bearing for nil allocation and non-nil reuse, including write-through/same-map behavior.

Exact-head required/code CI is green; the only red I see is the known Local Provision real-image advisory (#2851), which is non-blocking and unrelated to this helper-only change.
