Summary

  • The Codex client treats a literal <oai-mem-citation> as markup and drops everything between the first opening tag and the last closing tag, so a model that quotes the tag in prose loses the rest of its answer. The bridge and the adapter encoder now escape such mentions while keeping a real citation block (one whose body validates) byte for byte, in the streaming and buffered paths.
  • Streaming: a candidate block is held WHOLE until its closing tag arrives and is released verbatim only when its body validates, so streamed deltas equal the final output_text.done text. A tag split across deltas is handled; an invalid, never-closed or over-16 KiB candidate is escaped. The held bytes are charged to the translator budget (live_transient) and released when the message closes. The Responses bridge and the adapter encoder each keep one escaper per message.
  • The Argon thinkingLevel fix that used to live here moved to fix(antigravity): name the Argon tier in thinkingConfig so thought text streams #8139 at the maintainer's request; the two are independent.
  • Owning contract updated in place: structure/transports/responses-wire-shapes.md.

Verification

  • bun x tsc --noEmit, bun run structure:check, bun run privacy:scan: pass
  • bun test tests/responses/citation-markers.test.ts tests/responses/protocol-direct-encoders-chat.test.ts plus the two Argon test files: 120 pass / 0 fail. New cases: real block split one character at a time, a two-way-split parity sweep, Chat-encoder and Responses-bridge delta/done parity, held-bytes charge and release (fails without the budget code), and an oversized candidate being escaped.
  • After review fixes and merging current dev (head a21626617): bun run typecheck passes; every test file importing citation-markers, anthropic-progress, bridge/sse or adapter-events passes (4 files, 168 pass, 0 fail). Signed progress text now escapes its visible copy; a valid block above the hold limit now gets the same rule in deltas and in the final text.
  • Full suite not run locally (Windows, slow); left to CI.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Review readiness checklist

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:

  • Required local validation passed; commands, results, and any full-suite exception are documented.

  • I pushed my PR to a recent dev commit (at most 10 behind; a maintainer may still ask for the exact tip before merge).

  • I resolved all correct Codex and CodeRabbit findings.

  • My PR is ready for review.

Summary by CodeRabbit

  • Bug Fixes

    • Literal or malformed memory-citation tags are now escaped in Responses output by default, including when text is streamed. Valid, complete citation blocks remain unchanged.
    • Visible text in signed progress updates receives the same escaping, while the signed content remains intact.
    • Chat Completions and Messages delivery paths retain their existing unescaped text behavior.
    • Escaping can be disabled through an option for applicable Responses bridges.
  • Documentation

    • Clarified how citation-tag escaping and signed progress text are handled.

Maintainer follow-up (bundle lane, head 19921bf)

Commits added on this branch by a maintainer (no force push): a merge of current dev and one fix commit for the open review items.

  • Responses wire only. encodeAdapterEventStream serves only Chat Completions and Messages, whose clients never parse <oai-mem-citation>, so its hunks are reverted. Both Responses bridges also replay Chat/Messages turns. They now take escapeMemoryCitationTags (default true), and the delivery and run-turn paths pass false for chat/anthropic inbound wires. stripCitationMarkers no longer escapes by itself.
  • Real block shape. A complete <citation_entries> list right after the open tag is enough. The client's parse_memory_citation accepts a block without <rollout_ids>/<thread_ids>, so requiring one escaped real blocks that dev passed through.
  • Wording (Ingwannu's notes). Comments and contracts now state:
    • the client hides from an opening tag to the FIRST closing tag, or to EOF when no closing tag follows (openai/codex utils/stream-parser/src/citation.rs);
    • the hold limit is 16,384 UTF-16 units;
    • an escaped tag stays visible as &lt; inside code spans, the accepted cost of keeping the rest of the answer.
  • Contracts. structure/providers/anthropic-progress.md names the escaped mirror form.
  • Tests.
    • Chat/Messages paths keep the raw tag, both streaming and buffered.
    • A buffered Responses body escapes the mention.
    • An entries-only block stays real.
    • The progress item's content[0].text is asserted directly.

Verification at 19921bf:

  • Symptom. On origin/dev, the Responses bridge emits quoted <oai-mem-citation> prose and the rest raw, and the Codex client hides everything after the quote. This branch emits quoted &lt;oai-mem-citation> prose and the rest.
  • tests/responses/citation-markers.test.ts: 39 pass.
  • File-size ratchet, test layout, Lab boundary, bun run typecheck, structure:check and privacy:scan pass.
  • bun test --changed=<merge-base>: 38559 pass / 65 fail / 14 errors. Every failing file is in the launcher/FIFO/catalog-sync set that fails identically on unmodified dev on this macOS host.
  • NOT RUN: the full suite, Windows/macOS lanes, and a live Codex client render.

…om truncating answers

Gemini 4 Argon answers through CCA with thought parts only when the request names
its tier in thinkingConfig. The Argon wire ids already carry the tier as a suffix
(gemini-4-argon-high), so the adapter sent includeThoughts alone; live CCA then
returns 200 with thousands of thoughtsTokenCount and zero thought parts, and the
plan arrives as ordinary visible text. Measured 2026-10-27: the same request with
thinkingLevel repeated alongside includeThoughts returns the thought stream, while
gemini-3.8-flash does not need it and keeps its one-field shape.

Separately, the Codex client treats a literal <oai-mem-citation> as markup and
drops everything between the first opening tag and the last closing tag. A model
that quotes the tag in prose loses the rest of its answer, which reads as a turn
truncated at a backtick. The bridge now escapes mentions while leaving a real
citation block (one whose body starts with <citation_entries>) byte for byte, in
both the streaming and buffered paths.

Walkthrough

The change adds whole-string and streaming handling for memory-citation tags. Responses bridges apply configurable escaping to text, while signed-progress envelopes retain raw text and visible text can be escaped.

Changes: Memory Citation Escaping

Layer / File(s) Summary
Citation escaping and validation
src/responses/citation-markers.ts, tests/responses/citation-markers.test.ts
Whole-string and streaming escapers preserve qualifying blocks and escape tags outside them. Tests cover split tags, incomplete or invalid blocks, and candidates over the 16,384-character limit.
Response bridge and delivery integration
src/bridge/sse.ts, src/bridge/response-json.ts, src/server/responses/*, src/images/loop.ts, src/web-search/loop.ts, src/server/inference/client-encoder-delivery.ts, tests/responses/citation-markers.test.ts, tests/web-search/web-search-memory-citation.test.ts, tests/fixtures/test-layout-expected.json, scripts/test-layout/layout-adapters.json, structure/transports/responses-wire-shapes.md
Streaming and buffered Responses paths escape memory-citation mentions by default and accept an option to disable escaping. The streaming bridge holds candidate text per message and accounts for pending text against the translator budget. Delivery wiring sets the option according to the inbound wire or run-turn setting. Tests cover output parity and option behavior.
Signed-progress text handling
src/responses/anthropic-progress.ts, src/bridge/sse.ts, src/bridge/response-json.ts, tests/responses/citation-markers.test.ts, structure/providers/anthropic-progress.md
Signed-progress visible text can be escaped while the reasoning envelope retains raw text. Mirror detection accepts visible text matching the original or escaped text.

The change escapes quoted memory-citation tags in Responses output and passes valid citation blocks through unchanged. The two earlier open concerns no longer apply at this head, and no new concrete risk was found. The author did not run the full test suite, cross-platform lanes, or a live client render, so the change carries only normal pre-merge validation risk.

Minor · Keep the Argon level when discovery resolves a suffix id. · antigravity-models.ts:788

src/providers/antigravity-models.ts:788
Minor · Functional Correctness · Quick win

Keep the Argon level when discovery resolves a suffix id.

When discovery lists only one Argon tier, the lone row keeps its suffix id, for example gemini-4-argon-high. A request for that id then returns from the discovered-id branch before the Rule 1 suffix logic runs. That branch adds no thinkingLevel for Argon, so the request omits the level that exposes thought parts.

The branch is reached because gemini-4-argon-high is not a key in ANTIGRAVITY_EFFORT_WIRE_MAP or ANTIGRAVITY_THINKING_LEVEL_MODELS. Discovery is therefore consulted for it. Rule 1 would add thinkingLevel for this id. The discovered-id branch returns first.

A complete Argon family does not reach this path. The family collapses to the base id, which is handled by the explicit-effort rules.

Apply the same Argon suffix handling inside the discovered-id branch:

Suggested fix
   if (discoveredWireModelId && (discoveredWireModelId !== modelId || isAntigravitySuffixModelId(modelId))) {
     const defaultLevel = ANTIGRAVITY_THINKING_LEVEL_MODELS[modelId];
+    // Argon's suffix tier must reach thinkingConfig on this path too, matching Rule 1.
+    const argonSuffix = /^gemini-4-argon-(low|medium|high)$/.exec(discoveredWireModelId);
+    if (argonSuffix) return { wireModelId: discoveredWireModelId, thinkingLevel: argonSuffix[1]! };
     return {
       wireModelId: discoveredWireModelId,
       ...(defaultLevel

Add a regression test that registers a partial Argon discovery with only one tier row. Assert that a request for that suffix id carries the matching thinkingLevel.

Changes requested for 43403a2e495d7e9e250a8b8a027eb3ad27c7d3b9.

  1. src/responses/citation-markers.ts:218-240: a real streamed citation loses its closing tag. push() emits the opening tag once <citation_entries> is seen, but keeps no in-block state, so the closing-tag branch always emits &lt;/oai-mem-citation>. A complete block therefore differs between deltas and output_text.done. I independently reproduced this on Bun 1.4.4 by feeding the existing valid-block fixture one character at a time: the full-string helper preserves it, while the streaming helper changes the close tag. Track the block through its close and define the incomplete/invalid-body behavior; add a full real-block streaming regression and assert delta/done parity.

  2. src/protocols/encoders/adapter-events.ts:609: the per-delta whole-string helper misses an ordinary mention split as "quoted <oai-mem-", "citation> prose". Independently invoking the exact two helper calls used at this site reproduces the raw tag instead of the escaped mention. Use message-owned incremental state on this encoder too, flush it on close, and add an encoder-level split-delta regression. These independently confirm the two existing CodeRabbit threads; they should remain open until corrected.

The two scratch repros failed as expected (0 pass / 2 fail), using disposable homes and CPU75%/1536MiB/no-swap/64-task cgroup limits. No live provider/client call or scan was used. This is failure evidence, not a green suite or a full Argon validation.

Please also split the unrelated Argon effort-wire and client citation-rendering fixes into separate reviewable changes, as the description already offers. Update the relevant owning structure contracts (Argon suffix/thought-level and citation/streaming accounting); the current six-file diff changes neither owning document despite changing both contracts. Recheck the existing byte-budget/partial-tail behavior when adding escaper state rather than introducing an unbounded uncharged buffer.

Nitpick Parameterize the lone-tier Argon discovery test across all three tiers.

103-106: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Parameterize the lone-tier Argon discovery test across all three tiers.

The lone-tier branch in resolveAntigravityEffortWireModel (src/providers/antigravity-models.ts) derives thinkingLevel from the captured tier in the wire id. The test at tests/adapters/google/antigravity-discovered-families.test.ts:103-106 registers only gemini-4-argon-high. A regression that hard-codes high in that branch would still pass. Parameterizing the test over low, medium, and high makes it assert that thinkingLevel equals the registered tier. The file-level afterEach hooks reset the discovery registration between tests, so the generated cases do not share state.

Suggested test change
-test("a lone discovered Argon tier keeps its level so thought text still streams", () => {
-  const rows = parseAntigravityAvailableModels(payload("gemini-4-argon", ["high"]))!;
-  registerAntigravityDiscoveredWireModels(baseUrl, rows);

@Ingwannu e9de0e6d4 addresses the two streaming defects from your review. Could you re-check those when you have time?

  1. Closing tag lost in a streamed block: the streaming escaper now holds a candidate <oai-mem-citation> block whole until it closes. A valid block is released verbatim with both tags, so deltas match output_text.done. A block that closes without a valid body is escaped as a mention. The hold is capped at 64 KiB; past that cap the text is treated as a mention. tests/responses/citation-markers.test.ts adds a char-by-char real-block regression with delta/done parity.
  2. Split mention in the adapter encoder: adapter-events.ts now keeps per-message escaper state, flushes it when the message closes, and has an encoder-level split-delta regression ("quoted <oai-mem-" + "citation> prose").

Still open from your review, so this is not ready yet:

  • splitting the Argon effort-wire change and the citation-rendering fix into separate PRs;
  • updating the owning structure contracts (Argon suffix/thought level, and citation/streaming accounting);
  • rechecking the byte-budget accounting: the 64 KiB hold is bounded but not yet charged against the partial-tail budget.

Nitpick Assert the visible message item text in the signed-progress test.

403-410: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Assert the visible message item text in the signed-progress test.

The test named signed progress text escapes only its visible copy does not check the escaped text of the visible message item. Its only check on that item is isAnthropicProgressMirror(...), which accepts both the raw and the escaped text. If the message item in anthropicProgressItems stopped escaping, the test would still pass. The response.output_item.done item and buffered output would then contain the raw <oai-mem-citation> tag. Add a direct assertion on the item content:

🧪 Suggested test assertion
     expect(isAnthropicProgressMirror(items.find(item => item.type === "message"), envelope)).toBe(true);
+    const message = items.find(item => item.type === "message") as { content?: { text?: string }[] } | undefined;
+    expect(message?.content?.[0]?.text).toBe(escaped);

Leave isAnthropicProgressMirror unchanged. The new assertion checks the visible item directly.

Measure the memory-citation hold limit in UTF-8 bytes.

MAX_MEMORY_CITATION_HOLD (16,384) is compared with UTF-16 string lengths, but the contract is 16 KiB. A multibyte candidate can therefore hold up to three times the documented bytes. The held bytes are then charged to the budget as UTF-8, so the overshoot reaches the budget.

This change escapes valid multibyte blocks above 16 KiB in bytes that the current code preserves. If the team instead intends UTF-16 units, update the 16 KiB wording in structure/transports/responses-wire-shapes.md:598 to match.

Require a closing </rollout_ids> in the citation block check.

MEMORY_CITATION_BODY accepts a body with an opening <rollout_ids> and no closing tag. The block is then kept verbatim instead of being escaped. The invalid-block test does not cover this input, so the test suite does not detect it. Change the pattern to require </rollout_ids> after <rollout_ids>, and add the malformed input to the invalid-block cases.

Update MEMORY_CITATION_BODY to require a closing rollout_ids tag after its
opening tag, so blocks missing it are not treated as valid citations. Add a
malformed citation with an unclosed rollout_ids section to the invalid-block
cases in the streamed test.

Re-reviewed at a21626617b44813c12f45e9a9fc77a881d33a65f (static review; no local execution).

The blockers from my earlier change request are resolved at this head:

  1. A real streamed block now keeps its closing tag. createMemoryCitationEscaper (src/responses/citation-markers.ts:205-266) holds a candidate block until it closes and shares opensRealBlock and the size rule with the whole-string form. The char-by-char, two-way-split and bridge delta/done parity tests cover this.
  2. adapter-events.ts keeps one escaper per message and resolves the held text in closeCurrentMessage. The Chat-encoder split-mention regression covers it.
  3. The Argon change was split out to #8139. Held bytes are charged as live_transient and released on close.

Before approval:

  • Hosted CI had not run on this head; I have approved the fork runs (Cross-platform CI, Catalog async contracts). We need gates and test changed green on this exact head.
  • structure/providers/anthropic-progress.md:30 still says the parser drops the commentary copy only on "exact text". isAnthropicProgressMirror (src/responses/anthropic-progress.ts:30-31) now also accepts the escaped copy. Please update the owning contract.
  • Please answer the two open CodeRabbit threads:
    • citation-markers.ts:127: the limit is 16,384 UTF-16 units while the contract says "16 KiB". Measure in bytes or fix the wording.
    • citation-markers.test.ts:294: see the next point. I think that suggestion should be declined.

Non-blocking notes:

  • citation-markers.ts:84 requires <rollout_ids>. Codex's parse_memory_citation (codex-rs/memories/read/src/citations.rs) accepts entries without an ids block, and also <thread_ids>. If a model leaves out <rollout_ids>, the block is now escaped and shown as raw text instead of being parsed as a citation, which is a regression from current dev. Consider requiring only a complete <citation_entries>…</citation_entries> directly after the open tag, rather than tightening further.
  • citation-markers.ts:66-71, :135-136 and responses-wire-shapes.md:598 describe the client as hiding up to the last closing tag. codex-rs/utils/stream-parser/src/citation.rs matches literally and non-nested up to the first close, and an unclosed open tag hides the rest at EOF. The comment also says &lt; "keeps the same visible characters in every renderer". CommonMark does not decode entities in code spans or fenced code, so the PR's own example, `<oai-mem-citation>`, displays as &lt;oai-mem-citation>. Please correct the wording and state this trade-off.
  • tests/responses/citation-markers.test.ts:403-410 checks the visible item only through isAnthropicProgressMirror, which accepts both forms. Assert content[0].text equals the escaped text directly.
  • Question: the escaping also applies to the Chat Completions and Messages encoders (adapter-events.ts:617, :637-641), whose clients do not parse <oai-mem-citation>. Is rewriting their text to &lt; intended there?

… only

Maintainer follow-up to the review on lidge-jun#8044:
- Chat Completions and Messages clients never parse <oai-mem-citation>, so the
  adapter-events encoder changes are reverted and both Responses bridges take
  escapeMemoryCitationTags (default true); Responses delivery and run-turn
  paths pass false for chat/anthropic inbound wires. stripCitationMarkers no
  longer escapes on its own.
- A real block needs only a complete <citation_entries> list; the client's
  parse_memory_citation accepts a block without <rollout_ids> or <thread_ids>,
  so requiring one regressed dev.
- Comments and contracts state the client hides to the FIRST closing tag (or
  EOF), that the hold limit is UTF-16 units, and the code-span trade-off; the
  progress mirror contract names the escaped form.
- Tests: Chat/Messages paths keep raw text (stream and buffered), buffered
  Responses escapes, an entries-only block stays real, and the progress item's
  visible text is asserted directly.

Maintainer judgment (bundle lane: Anthropic / Chat protocol fixes, head 19921bf5a9)

  • Value: when a model quotes the memory-citation tag in prose, the Codex client hides everything after the quote, because it auto-closes an unterminated tag at the end of the stream. The answer looks truncated. Ingwannu cleared the blockers on 2026-11-04, the PR has had no activity since, and the defect is still on dev.
  • Scope of the UX change: only Responses (Codex) output changes. A quoted tag outside a real citation block shows as &lt;oai-mem-citation>; real citation blocks pass through byte for byte, including ones without an ids list. Chat Completions and Messages output is unchanged.
  • Regression evidence for existing users: real-block parity holds for streamed deltas against output_text.done, for every two-way split and for one-character splits. Chat/Messages raw-text tests are in place, and the entries-only block that the earlier head would have escaped now stays real. --changed failures reproduce on unmodified dev.
  • Windows: no platform-specific code.
  • Verification: see "Maintainer follow-up" in the description.
  • NOT RUN: the full suite, cross-platform lanes, and a live Codex render.

… candidate scans

Review follow-up on lidge-jun#8044:
- The web-search and image sidecar loops bridge every inbound wire; they now
  take escapeMemoryCitationTags and sidecar-execution passes false for chat
  and anthropic, so those clients receive the raw tag. The Chat/Messages
  completion fold also keeps the raw text its fingerprints compare.
- A block carrying only <rollout_ids> or <thread_ids> is real, matching the
  client's parse_memory_citation.
- Candidate scans look at most one hold limit ahead and share the next
  closing-tag search; outside claimed blocks one regex pass escapes. A 3 MB
  input of unclosed candidates went from ~10 s to ~0.1 s.
