Summary

Fixes E2E Chat deterministically failing in CI: runtime registry: manifest.json load failed (invalid character '/' after top-level value) -- using fallback allowlist.

The repo-root manifest.json has a trailing JSON5-style // comment (// Triggered by Integration Tester at 2026-05-10T08:52Z) appended by the CI trigger. Go's encoding/json throws on the /, causing loadRuntimesFromManifest to fall back to the hardcoded allowlist -- the echo runtime is never registered, so all round-trip Chat tests fail.

Fix: bytes.LastIndex(data, []byte("}")) + slice before json.Unmarshal, so any trailing comment or garbage after the closing brace is silently discarded.

Test plan

  • go test ./internal/handlers/... -run TestLoadRuntimesFromManifest -> 6/6 passed (2 new)
  • Verified real manifest.json (with trailing // comment) now parses to 6 templates
  • Go full suite: all packages OK
  • Canvas full suite: 3311 passed

Closes #1480

The repo-root manifest.json has a trailing JSON5-style // comment
appended by the Integration Tester CI trigger (// Triggered by
Integration Tester at 2026-05-10T08:52Z).  Go's encoding/json throws
"invalid character '/' after top-level value" on the '/', causing
loadRuntimesFromManifest to fall back to the fallback allowlist at
runtime registry init.  In E2E Chat runs (MOLECULE_ENV=development),
the platform server starts from workspace-server/ and resolves
../manifest.json — the file with the trailing comment — so the echo
runtime is never registered and all round-trip Chat tests fail.

Fix: bytes.LastIndex(data, []byte("}")) + slice to that position
before json.Unmarshal, so any trailing comment or garbage after the
closing brace is discarded silently.

Two regression tests added:
- TestLoadRuntimesFromManifest_StripsJSON5TrailingComment:
  real manifest content + "// Triggered by ..." after }
- TestLoadRuntimesFromManifest_ExtraDataAfterClosingBrace:
  valid JSON + arbitrary trailing text

Closes #1480

[core-qa-agent] APPROVED — simplifies #1483 fix: truncates at last } instead of character-by-character scan. Regression test added. Go tests PASS. e2e: N/A — Go/workspace-server handler only.

infra-sre review — PR #1485

APPROVE — simpler alternative to #1483's JSON5 stripping.

Approach

Instead of a full JSON5 comment scanner, uses bytes.LastIndex(data, "}") to truncate at the last } before json.Unmarshal. Simpler and equally correct for the manifest.json use case.

Why this works for manifest.json

Manifest entries are JSON arrays of objects: [{...}, {...}]. Any } in the content would be inside string values (field names/values), which always appear before the structural } characters. Truncating at the last } correctly preserves all content and drops trailing // comments or any other garbage.

Edge cases covered by tests

  1. Trailing JSON5 comment — // Triggered by Integration Tester at ... stripped, langgraph and other runtimes correctly loaded.
  2. Arbitrary trailing data — anything after the last } is discarded; valid JSON body still parsed.

Relationship to #1483

Both PRs fix the same root cause (Integration Tester appends // Triggered by ... to manifest.json). #1483 does full JSON5 stripping; #1485 uses simpler truncation. These are alternate approaches — author should close one after the other merges. #1485's simplicity (55 additions vs 207 in #1483) is a point in its favor for the manifest-only fix.

No infra concerns.

[core-security-agent] APPROVED — OWASP Injection clean. Truncates manifest.json at last } via bytes.LastIndex before json.Unmarshal — strips trailing JSON5 // comments appended by Integration Tester. No user input, no exec. Regression tests verify truncation correctness. Handler auth unchanged.
