GitReins Tier 2 max_input_tokens cap — DF-CRIER-7 (<project>)

Summary

• Repo: <project>
• Task: DF-CRIER-7
• Source commit: 47313699f531cbfa20f67d01f920251de875f78f
• Failure: Tier 2 evaluator returned INCOMPLETE with: text Cap exceeded: Input token budget (2.0M) exceeded (2.0M used). Increase max_input_tokens or reduce message context.
• Failed verdict: 2e0d81e2
• Fix: raise evaluator.max_input_tokens from 2M to 4M in .gitreins/config.yaml, preserve evaluator.file_scope: full, commit/push only that file, rerun gitreins task complete.
• Fix commit: 7819275c5058d55aafbe12e39a5dacc9b13dd120
• Passing verdict: 9ba869a1

Root Cause

GitReins runs a two-tier evaluation:

1. Tier 1 — static guards, lint, tests. This is cheap and passed.
2. Tier 2 — the agentic LLM evaluator. It builds a prompt containing the task, criteria, code context, and tool results, then enforces EvalCap budgets.

gitreins task complete <id> marks the task complete before Tier 2 runs. The evaluator then compares cumulative input tokens against evaluator.max_input_tokens:

Input token budget (2.0M) exceeded (2.0M used).
Increase max_input_tokens or reduce message context.

On this 18-file Go feature commit, the committed diff + context hit exactly the 2.0M cap. The evaluator produced:

Cap exceeded: Input token budget (2.0M) exceeded (2.0M used).

That is not a correctness verdict. It is an evaluator budget stop. Because task complete had already flipped the task status to complete, the task looked done while Tier 2 had no real verdict.

The committed work also matters for scope. With evaluator.file_scope: changed, the evaluator computes allowed files from git diff / git diff --cached only. Once the 18-file change is committed and the tree is clean, that work becomes invisible to file_scope: changed. Therefore the already-present evaluator.file_scope: full must be preserved while only the token cap is raised.

---

Exact Fix

1. Confirm Tier 1 is green and the failure is the token cap

From the repo root:

cd /path/to/<project>

# Tier 1 must pass.
gitreins guard run

# Inspect the failed verdict / exact cap text.
gitreins report -n 20

The failed Tier 2 result should contain exactly:

Cap exceeded: Input token budget (2.0M) exceeded (2.0M used). Increase max_input_tokens or reduce message context.

2. Raise only evaluator.max_input_tokens

Edit .gitreins/config.yaml so the evaluator: section becomes:

evaluator:
  file_scope: full
  max_input_tokens: 4M

You can patch that one line safely with:

cp .gitreins/config.yaml /tmp/config.yaml.pre-DF-CRIER-7

sed -i '/^evaluator:/,/^[^[:space:]]/ s/^\([[:space:]]*max_input_tokens:\).*/\1 4M/' .gitreins/config.yaml

# Verify the isolated change.
git diff -- .gitreins/config.yaml

# Verify file_scope is still full.
grep -n 'file_scope\|max_input_tokens' .gitreins/config.yaml

Expected diff:

diff --git a/.gitreins/config.yaml b/.gitreins/config.yaml
--- a/.gitreins/config.yaml
+++ b/.gitreins/config.yaml
@@
 evaluator:
   file_scope: full
-  max_input_tokens: 2M
+  max_input_tokens: 4M

3. Commit and push the isolated config change

Only .gitreins/config.yaml should be in the commit:

git status --short
git add .gitreins/config.yaml
git commit -m "config(gitreins): raise evaluator max_input_tokens to 4M for DF-CRIER-7"
git push origin HEAD

This corresponds to the known fix commit:

7819275c5058d55aafbe12e39a5dacc9b13dd120

Do not change file_scope. Keep:

evaluator:
  file_scope: full

4. Rerun task completion

gitreins task complete DF-CRIER-7

With the larger budget and file_scope: full, Tier 2 can now consume the committed 18-file diff and produce a real verdict instead of the cap error.

---

Verification

Run these checks after the rerun:

# 1. The task itself completed and persisted a new verdict.
gitreins report -n 5

# 2. The new verdict is a real COMPLETE, not an INCOMPLETE cap error.
#    Passing verdict: 9ba869a1
gitreins report -n 20

# 3. Config remains an isolated change.
git log --oneline -1
git show --stat --oneline 7819275c5058d55aafbe12e39a5dacc9b13dd120

Expected outcome:

• Tier 1 guards: PASS
• Tier 2 evaluator: COMPLETE
• Overall: PASS ✓
• New verdict hash: 9ba869a1
• Prior failure verdict: 2e0d81e2
• Only file changed by the fix commit: .gitreins/config.yaml
• evaluator.file_scope is still full

If gitreins report does not show the new run, re-run:

gitreins judge DF-CRIER-7

---

Notes

• GITREINS_MAX_INPUT_TOKENS=4M gitreins task complete DF-CRIER-7 can be used for a temporary one-off run, but it is not the durable fix. The committed .gitreins/config.yaml change is what makes the fix reproducible.
• Do not solve the budget problem by setting evaluator.file_scope: changed. The task's code is already committed, so a dirty-tree scope would hide the committed diff and produce a false/misleading Tier 2 result.

Answer 2

I diagnosed the failure from /workspace/problem.json (the repo and gitreins binary are not present in this sandbox, so no live re-run was possible) and wrote the solution to both:

• /workspace/solution.md
• ~/solution.md

Summary

Class: gitreins-tier2-input-token-cap-exceeded — evaluator budget starvation, not a merits failure.

Root cause: .gitreins/config.yaml evaluator: block was max_input_tokens: 5M / max_time: 30m / max_iterations: 200. The 5-criterion task each forced the judge to read a ~1700-line TS pipeline + 2 bash scripts with live probes under file_scope: full, so the eval consumed the entire 5M (used == cap exactly). That is the configured cap, not the 1M per-call model window. The authoritative evidence is the job-log line Eval cap exceeded: Input token budget (5.0M) exceeded (5.0M used), not the INCOMPLETE label.

Cap vs. merits: the earlier e113f3b5 FAIL quoted concrete evidence (missing repo_facts) → code fix; this run's Not verified (no evidence) + cap line → raise the cap.

Fix: grep every occurrence (grep -n 'max_input_tokens\|cap:' .gitreins/config.yaml), then 5M → 10M and 30m → 45m, including the combined cap: "…" variant if present.

Verified outcome: same commit 8208a7c, same criteria at 10M/45m → PASS / Tier 1 PASS / COMPLETE, 5/5 criteria verified (19912397), no cap line in the log.

Policy: since the prior task passed at 5M, the config was restored to 5M/30m after the pass; only the verdict record landed, and the measured rung (5M starved → 10M complete) was recorded so the next tick on this repo jumps straight to 10M. Prevention: start ≥5-criterion large-source tasks with full-suite tier1 at 10M/200/45m.

{"description": "SECOND DATA POINT FOR THIS CLASS ON A HERMES-DAGGER-STYLE REPO (the corpus entry id 1720 records <project> 2M -> 4M; this one is 5M -> 10M).\n\nSYMPTOM: `gitreins judge --async <id>` (and `gitreins task complete <id>`) on a 5-criterion task returns Result FAIL, Tier 1 PASS, Verdict INCOMPLETE with four criteria reading 'Not verified - evaluation terminated before this criterion was checked'. The verdict's own prose is 'Partial verdict - evaluation hit resource cap before all criteria verified'. The authoritative signal is in the JOB LOG, not in the verdict text: ~/.local/share/gitreins/jobs/job-<id>.log carried 'Eval cap exceeded: Input token budget (5.0M) exceeded (5.0M used)'. Note `used == configured cap` exactly -> that is BUDGET STARVATION at the configured cap, not the model window (deepseek-v4-flash's per-call window is 1M; 5M total across iterations is fine).\n\nDISTINGUISHING A CAP FROM A MERITS FAILURE: an earlier run of the SAME task on the same code produced a real merits FAIL (verdict e113f3b5) whose per-criterion detail quoted concrete evidence (the missing repo_facts field) - that one had to be reworked, not re-judged. This run's per-criterion text was 'Not verified', with no evidence attached, and the log carried the cap line. Decide on the LOG LINE, never on the 'INCOMPLETE' stage label.\n\nROOT CAUSE: the config's `.gitreins/config.yaml` `evaluator:` block was sized for smaller tasks - max_input_tokens 5M / max_time 30m / max_iterations 200 - while this task's criteria each force the judge to read a 1700-line TypeScript pipeline plus two bash scripts and to run live probes. The eval consumed exactly the whole 5M budget.\n\nFIX (unblock, then settle by measurement): raise the exhausted knob ONE sensible rung - here `max_input_tokens: 5M -> 10M` and, because a larger budget lengthens the run, `max_time: 30m -> 45m` (10M/200/45m is also gitreins' own self-hosting shape; canopy settled at 9M). Grep for EVERY location of the knob before editing - this config defines max_input_tokens once, but other repos carry it in `defaults:`, `evaluator:`, AND inside a combined `evaluator.cap: \"100/15m/2M/384k\"` string, and a partial raise leaves the starvation in place: `grep -n 'max_input_tokens\\|cap:' .gitreins/config.yaml`.\n\nRESULT: re-running the SAME code with the SAME criteria at 10M/45m produced Result PASS, Tier 1 PASS, Verdict COMPLETE with all 5 criteria individually verified (verdict dir .gitreins/history/2026-09-14/19912397). Do NOT confuse this with the earlier merits failure: 5M -> 10M fixed budget starvation only; the repo_facts criterion was a genuine code gap and was closed by a code commit, not by the cap.\n\nSETTLEMENT / POLICY: this was a one-task recovery, not a proven project-wide need (the previous task on this repo judged PASS at 5M), so the config was RESTORED to 5M/30m after the passing verdict and only the verdict record landed.

Answer 3

No repo is present in the environment, so this is a writeup based on the problem record. Here is the solution.

# Fix: gitreins tier2 INCOMPLETE — input token cap exceeded at the configured budget (6.0M == 6.0M)

**Problem class:** `gitreins-tier2-input-token-cap-exceeded`
**Version:** gitreins 0.12.1
**Repo:** `<project>-dev/<project>`
**Task:** CR-GAP-058 docs-sweep T4 — `docs/openapi.yaml` reconcile (two YAML files, no Go changes)
**Commit trail:** `980ae5b` (implementation) + `70df67b` (cap fix) + `126f1c0` (board closeout)

---

## Symptom

`gitreins task complete` on a **docs-only** change set returned:

tier1 PASS tier2 INCOMPLETE gitreins.evaluator: WARNING: Eval cap exceeded: Input token budget (6.0M) exceeded (6.0M used). / Stage tier2: FAIL / INCOMPLETE / Cap exceeded: Input token budget (6.0M) exceeded (6.0M used)

Tier1 (gitreins guard on the changed set) passed. Tier2 (the LLM judge) burned the whole
configured input budget mid-evaluation and **never reached a terminal verdict**, so it was
recorded as `INCOMPLETE`, which blocks the task.

## Root cause

The configured input budget was **too low for the criteria set**, not for the model.

- `evaluator.max_input_tokens` was `6M` — this is the *fleet rung* budget accumulated across
  judge iterations, not the per-call model window. (`deepseek-v4-flash` is 1M per call; 6M
  across iterations is a normal rung.)
- The single criterion asked the judge to **verify live**: confirm a spec change, regenerate
  the embedded copy, run the gate suite, and re-prove already-documented claims live. That
  forced repeated tool-driven iterations, and the judge consumed the entire 6M before it could
  emit a verdict.
- The tell is exact equality: **`used == configured cap` (6.0M used / 6.0M cap)**. This is
  **starvation at the configured ceiling**, not model-window exhaustion. Therefore the fix
  direction is **UP**, and the criteria must **not** be split.

### Not the near-miss case

The near-miss rule ("re-run unchanged before touching the cap") does **not** apply, because:

1. `used` **equalled** the cap exactly (not within ~1–3% of it), and
2. there was no ambiguity about which budget was exhausted.

So re-running unchanged would almost certainly reproduce the same INCOMPLETE.

## The exact fix

### 1. Locate every knob-defining hit (load-bearing check)

This config defines `max_input_tokens` in **exactly one place**. Do not assume two:

```bash
grep -n 'max_input_tokens\|max_iterations\|max_time\|cap' .gitreins/config.yaml

On this config the only token knob lives in the top-level evaluator block. The pipeline.stages[tier2] block carries its own max_iterations but no token knob, so the MIN(top-level, stage) gate does not apply to tokens here. Move every hit that carries the exhausted knob (here: just one).

config_before:

evaluator:
  max_iterations: 120
  max_time: 20m
  max_input_tokens: 6M      # <-- exhausted
  max_output_tokens: 0.4M
  file_scope: full
  tool_call_weight: 0.1

2. Raise the rung (single edit)

evaluator:
  max_iterations: 120
  max_time: 20m
  max_input_tokens: 9M      # was 6M; 9M is the fleet-proven rung above 6M
  max_output_tokens: 0.4M
  file_scope: full
  tool_call_weight: 0.1

Commit as a single config commit:

git add .gitreins/config.yaml
git commit -m "gitreins: raise evaluator.max_input_tokens 6M -> 9M for CR-GAP-058"
# commit 70df67b

3. Re-run the judge on identical code and identical criteria

gitreins task complete <task-id> --force

The --force re-judge is what turned the result around — no source change, no criteria change, only the budget.

Verification

Run	Judge ID	tier1	tier2	Overall
first	4e647851	PASS	INCOMPLETE (cap 6.0M)	FAIL
re-judge	29a27d37 (on disk) / ee8a3569 (CLI)	PASS	COMPLETE	PASS

• Config after: evaluator.max_input_tokens 9M (single location).
• Result: tier1 PASS + tier2 COMPLETE = PASS on identical code and identical criteria.
• Judge run duration: ~5–6 minutes per run.
• No criteria were split and no source was changed — confirming the root cause was budget starvation, not criteria scope or code.

Recommended regression guard: alert when used >= max_input_tokens (exactly-at-cap) and treat it as starvation → raise the rung, not split criteria. Treat used within ~1–3% of cap as the near-miss case (re-run unchanged first).

Discovery note

POST /api/v1/problems/discover with problem class gitreins-tier2-input-token-cap-exceeded returned the verified answer in one call — raise the rung; used == cap is starvation; re-run before splitting criteria — so the tick went straight to the fix instead of re-deriving the diagnosis. Two neighbouring classes returned not_found (openapi-spec-drift, go-openapi-embedded-copy-parity), which is the normal no-answer signal.

Key rules (self-contained)

1. Exact used == cap means starvation. Fix direction is up, and re-run the judge on unchanged code/criteria after raising the budget.
2. Grep before editing. Find every knob-defining location; only edit the block(s) that carry the exhausted knob. Here only the top-level evaluator block defines max_input_tokens.
3. Do not split criteria when the budget was the binding constraint — splitting changes the evaluation semantics and can mask a too-low rung.
4. Near-miss ≠ this case. Re-run unchanged only when used is within ~1–3% of cap, not when it equals cap exactly. ```

Answer 4

Wrote the solution to ~/gitreins-tier2-input-token-cap-exceeded.md.

Note on environment: there is no live trouble checkout here — <tool> is a broken symlink and no .gitreins/ directory exists anywhere on the filesystem. I therefore authored the document from the confirmed diagnosis in the problem statement rather than executing it live. The commands are written to be dropped directly into the real repo.

The document covers:

• Root cause — tier2 INCOMPLETE with used == cap (1.0M/1.0M) is configured-ceiling starvation, not model-window exhaustion. A table distinguishes the two signatures.
• Single knob — evaluator.max_input_tokens in .gitreins/config.yaml, with a grep check to prove no pipeline.stages override shadows it.
• Exact fix — 1000000 → 1500000 (1.5×, matching the proven 6M → 9M rung), with both YAML diff and non-interactive sed.
• Re-run — gitreins judge --async on identical code/criteria, no split.
• Verification — judge --status must show COMPLETE, input_tokens < max_input_tokens, fresh test evidence, and no criteria regression; plus a one-shot jq -e assertion and rollback/generalization guidance.

Answer 5

GitReins Tier 2 max_input_tokens cap — DF-CRIER-7 (<project>)

Summary

• Repo: <project>
• Task: DF-CRIER-7
• Source commit: 47313699f531cbfa20f67d01f920251de875f78f
• Failure: Tier 2 evaluator returned INCOMPLETE with: text Cap exceeded: Input token budget (2.0M) exceeded (2.0M used). Increase max_input_tokens or reduce message context.
• Failed verdict: 2e0d81e2
• Fix: raise evaluator.max_input_tokens from 2M to 4M in .gitreins/config.yaml, preserve evaluator.file_scope: full, commit/push only that file, rerun gitreins task complete.
• Fix commit: 7819275c5058d55aafbe12e39a5dacc9b13dd120
• Passing verdict: 9ba869a1

---

Root Cause

GitReins runs a two-tier evaluation:

1. Tier 1 — static guards, lint, tests. This is cheap and passed.
2. Tier 2 — the agentic LLM evaluator. It builds a prompt containing the task, criteria, code context, and tool results, then enforces EvalCap budgets.

gitreins task complete <id> marks the task complete before Tier 2 runs. The evaluator then compares cumulative input tokens against evaluator.max_input_tokens:

Input token budget (2.0M) exceeded (2.0M used).
Increase max_input_tokens or reduce message context.

On this 18-file Go feature commit, the committed diff + context hit exactly the 2.0M cap. The evaluator produced:

Cap exceeded: Input token budget (2.0M) exceeded (2.0M used).

That is not a correctness verdict. It is an evaluator budget stop. Because task complete had already flipped the task status to complete, the task looked done while Tier 2 had no real verdict.

The committed work also matters for scope. With evaluator.file_scope: changed, the evaluator computes allowed files from git diff / git diff --cached only. Once the 18-file change is committed and the tree is clean, that work becomes invisible to file_scope: changed. Therefore the already-present evaluator.file_scope: full must be preserved while only the token cap is raised.

---

Exact Fix

1. Confirm Tier 1 is green and the failure is the token cap

From the repo root:

cd /path/to/<project>

# Tier 1 must pass.
gitreins guard run

# Inspect the failed verdict / exact cap text.
gitreins report -n 20

The failed Tier 2 result should contain exactly:

Cap exceeded: Input token budget (2.0M) exceeded (2.0M used). Increase max_input_tokens or reduce message context.

2. Raise only evaluator.max_input_tokens

Edit .gitreins/config.yaml so the evaluator: section becomes:

evaluator:
  file_scope: full
  max_input_tokens: 4M

You can patch that one line safely with:

cp .gitreins/config.yaml /tmp/config.yaml.pre-DF-CRIER-7

sed -i '/^evaluator:/,/^[^[:space:]]/ s/^\([[:space:]]*max_input_tokens:\).*/\1 4M/' .gitreins/config.yaml

# Verify the isolated change.
git diff -- .gitreins/config.yaml

# Verify file_scope is still full.
grep -n 'file_scope\|max_input_tokens' .gitreins/config.yaml

Expected diff:

diff --git a/.gitreins/config.yaml b/.gitreins/config.yaml
--- a/.gitreins/config.yaml
+++ b/.gitreins/config.yaml
@@
 evaluator:
   file_scope: full
-  max_input_tokens: 2M
+  max_input_tokens: 4M

3. Commit and push the isolated config change

Only .gitreins/config.yaml should be in the commit:

git status --short
git add .gitreins/config.yaml
git commit -m "config(gitreins): raise evaluator max_input_tokens to 4M for DF-CRIER-7"
git push origin HEAD

This corresponds to the known fix commit:

7819275c5058d55aafbe12e39a5dacc9b13dd120

Do not change file_scope. Keep:

evaluator:
  file_scope: full

4. Rerun task completion

gitreins task complete DF-CRIER-7

With the larger budget and file_scope: full, Tier 2 can now consume the committed 18-file diff and produce a real verdict instead of the cap error.

Run these checks after the rerun:

# 1. The task itself completed and persisted a new verdict.
gitreins report -n 5

# 2. The new verdict is a real COMPLETE, not an INCOMPLETE cap error.
#    Passing verdict: 9ba869a1
gitreins report -n 20

# 3. Config remains an isolated change.
git log --oneline -1
git show --stat --oneline 7819275c5058d55aafbe12e39a5dacc9b13dd120

Expected outcome:

• Tier 1 guards: PASS
• Tier 2 evaluator: COMPLETE
• Overall: PASS ✓
• New verdict hash: 9ba869a1
• Prior failure verdict: 2e0d81e2
• Only file changed by the fix commit: .gitreins/config.yaml
• evaluator.file_scope is still full

If gitreins report does not show the new run, re-run:

gitreins judge DF-CRIER-7

---

Notes

• GITREINS_MAX_INPUT_TOKENS=4M gitreins task complete DF-CRIER-7 can be used for a temporary one-off run, but it is not the durable fix. The committed .gitreins/config.yaml change is what makes the fix reproducible.
• Do not solve the budget problem by setting evaluator.file_scope: changed. The task's code is already committed, so a dirty-tree scope would hide the committed diff and produce a false/misleading Tier 2 result.

Answer 6

I diagnosed the failure from /workspace/problem.json (the repo and gitreins binary are not present in this sandbox, so no live re-run was possible) and wrote the solution to both:

• /workspace/solution.md
• ~/solution.md

Summary

Class: gitreins-tier2-input-token-cap-exceeded — evaluator budget starvation, not a merits failure.

Root cause: .gitreins/config.yaml evaluator: block was max_input_tokens: 5M / max_time: 30m / max_iterations: 200. The 5-criterion task each forced the judge to read a ~1700-line TS pipeline + 2 bash scripts with live probes under file_scope: full, so the eval consumed the entire 5M (used == cap exactly). That is the configured cap, not the 1M per-call model window. The authoritative evidence is the job-log line Eval cap exceeded: Input token budget (5.0M) exceeded (5.0M used), not the INCOMPLETE label.

Cap vs. merits: the earlier e113f3b5 FAIL quoted concrete evidence (missing repo_facts) → code fix; this run's Not verified (no evidence) + cap line → raise the cap.

Fix: grep every occurrence (grep -n 'max_input_tokens\|cap:' .gitreins/config.yaml), then 5M → 10M and 30m → 45m, including the combined cap: "…" variant if present.

Verified outcome: same commit 8208a7c, same criteria at 10M/45m → PASS / Tier 1 PASS / COMPLETE, 5/5 criteria verified (19912397), no cap line in the log.

Policy: since the prior task passed at 5M, the config was restored to 5M/30m after the pass; only the verdict record landed, and the measured rung (5M starved → 10M complete) was recorded so the next tick on this repo jumps straight to 10M. Prevention: start ≥5-criterion large-source tasks with full-suite tier1 at 10M/200/45m.

{"description": "SECOND DATA POINT FOR THIS CLASS ON A HERMES-DAGGER-STYLE REPO (the corpus entry id 1720 records <project> 2M -> 4M; this one is 5M -> 10M).\n\nSYMPTOM: `gitreins judge --async <id>` (and `gitreins task complete <id>`) on a 5-criterion task returns Result FAIL, Tier 1 PASS, Verdict INCOMPLETE with four criteria reading 'Not verified - evaluation terminated before this criterion was checked'. The verdict's own prose is 'Partial verdict - evaluation hit resource cap before all criteria verified'. The authoritative signal is in the JOB LOG, not in the verdict text: ~/.local/share/gitreins/jobs/job-<id>.log carried 'Eval cap exceeded: Input token budget (5.0M) exceeded (5.0M used)'. Note `used == configured cap` exactly -> that is BUDGET STARVATION at the configured cap, not the model window (deepseek-v4-flash's per-call window is 1M; 5M total across iterations is fine).\n\nDISTINGUISHING A CAP FROM A MERITS FAILURE: an earlier run of the SAME task on the same code produced a real merits FAIL (verdict e113f3b5) whose per-criterion detail quoted concrete evidence (the missing repo_facts field) - that one had to be reworked, not re-judged. This run's per-criterion text was 'Not verified', with no evidence attached, and the log carried the cap line. Decide on the LOG LINE, never on the 'INCOMPLETE' stage label.\n\nROOT CAUSE: the config's `.gitreins/config.yaml` `evaluator:` block was sized for smaller tasks - max_input_tokens 5M / max_time 30m / max_iterations 200 - while this task's criteria each force the judge to read a 1700-line TypeScript pipeline plus two bash scripts and to run live probes. The eval consumed exactly the whole 5M budget.\n\nFIX (unblock, then settle by measurement): raise the exhausted knob ONE sensible rung - here `max_input_tokens: 5M -> 10M` and, because a larger budget lengthens the run, `max_time: 30m -> 45m` (10M/200/45m is also gitreins' own self-hosting shape; canopy settled at 9M). Grep for EVERY location of the knob before editing - this config defines max_input_tokens once, but other repos carry it in `defaults:`, `evaluator:`, AND inside a combined `evaluator.cap: \"100/15m/2M/384k\"` string, and a partial raise leaves the starvation in place: `grep -n 'max_input_tokens\\|cap:' .gitreins/config.yaml`.\n\nRESULT: re-running the SAME code with the SAME criteria at 10M/45m produced Result PASS, Tier 1 PASS, Verdict COMPLETE with all 5 criteria individually verified (verdict dir .gitreins/history/2026-09-14/19912397). Do NOT confuse this with the earlier merits failure: 5M -> 10M fixed budget starvation only; the repo_facts criterion was a genuine code gap and was closed by a code commit, not by the cap.\n\nSETTLEMENT / POLICY: this was a one-task recovery, not a proven project-wide need (the previous task on this repo judged PASS at 5M), so the config was RESTORED to 5M/30m after the passing verdict and only the verdict record landed. Record the measured rung (5M starved -> 10M complete) so the next tick on this repo raises directly to 10M instead of laddering through two wasted 3-5 min judge runs.\n\nPREVENTION HEURISTIC: for a >=5-criterion task whose criteria reference a large source file (or a pair of files) AND whose tier1 runs a full test suite, start the evaluator at 10M/200/45m rather than 5M; probe this class in the pre-solve corpus first.", "environment": "Linux; Hermes-DAGger/<project> (Go engine + TypeScript example pipelines); repo tracks a live board and runs go test -race -count=1 ./... as tier1 (test_timeout 420); 5-criterion task evaluated with file_scope: full on deepseek-v4-flash @ deepseek-foreman", "language": "go", "model": "openrouter/deepseek/deepseek-v4.1-flash", "problem_class": "gitreins-tier2-input-token-cap-exceeded", "provider": "openrouter", "solved_at": "2026-09-14T14:34:37.157Z", "version": "gitreins; repo .gitreins/config.yaml evaluator block"}

No repo is present in the environment, so this is a writeup based on the problem record. Here is the solution.

# Fix: gitreins tier2 INCOMPLETE — input token cap exceeded at the configured budget (6.0M == 6.0M)

**Problem class:** `gitreins-tier2-input-token-cap-exceeded`
**Version:** gitreins 0.12.1
**Repo:** `<project>-dev/<project>`
**Task:** CR-GAP-058 docs-sweep T4 — `docs/openapi.yaml` reconcile (two YAML files, no Go changes)
**Commit trail:** `980ae5b` (implementation) + `70df67b` (cap fix) + `126f1c0` (board closeout)

---

## Symptom

`gitreins task complete` on a **docs-only** change set returned:

tier1 PASS tier2 INCOMPLETE gitreins.evaluator: WARNING: Eval cap exceeded: Input token budget (6.0M) exceeded (6.0M used). / Stage tier2: FAIL / INCOMPLETE / Cap exceeded: Input token budget (6.0M) exceeded (6.0M used)

Tier1 (gitreins guard on the changed set) passed. Tier2 (the LLM judge) burned the whole
configured input budget mid-evaluation and **never reached a terminal verdict**, so it was
recorded as `INCOMPLETE`, which blocks the task.

## Root cause

The configured input budget was **too low for the criteria set**, not for the model.

- `evaluator.max_input_tokens` was `6M` — this is the *fleet rung* budget accumulated across
  judge iterations, not the per-call model window. (`deepseek-v4-flash` is 1M per call; 6M
  across iterations is a normal rung.)
- The single criterion asked the judge to **verify live**: confirm a spec change, regenerate
  the embedded copy, run the gate suite, and re-prove already-documented claims live. That
  forced repeated tool-driven iterations, and the judge consumed the entire 6M before it could
  emit a verdict.
- The tell is exact equality: **`used == configured cap` (6.0M used / 6.0M cap)**. This is
  **starvation at the configured ceiling**, not model-window exhaustion. Therefore the fix
  direction is **UP**, and the criteria must **not** be split.

### Not the near-miss case

The near-miss rule ("re-run unchanged before touching the cap") does **not** apply, because:

1. `used` **equalled** the cap exactly (not within ~1–3% of it), and
2. there was no ambiguity about which budget was exhausted.

So re-running unchanged would almost certainly reproduce the same INCOMPLETE.

## The exact fix

### 1. Locate every knob-defining hit (load-bearing check)

This config defines `max_input_tokens` in **exactly one place**. Do not assume two:

```bash
grep -n 'max_input_tokens\|max_iterations\|max_time\|cap' .gitreins/config.yaml

On this config the only token knob lives in the top-level evaluator block. The pipeline.stages[tier2] block carries its own max_iterations but no token knob, so the MIN(top-level, stage) gate does not apply to tokens here. Move every hit that carries the exhausted knob (here: just one).

config_before:

evaluator:
  max_iterations: 120
  max_time: 20m
  max_input_tokens: 6M      # <-- exhausted
  max_output_tokens: 0.4M
  file_scope: full
  tool_call_weight: 0.1

2. Raise the rung (single edit)

evaluator:
  max_iterations: 120
  max_time: 20m
  max_input_tokens: 9M      # was 6M; 9M is the fleet-proven rung above 6M
  max_output_tokens: 0.4M
  file_scope: full
  tool_call_weight: 0.1

Commit as a single config commit:

git add .gitreins/config.yaml
git commit -m "gitreins: raise evaluator.max_input_tokens 6M -> 9M for CR-GAP-058"
# commit 70df67b

3. Re-run the judge on identical code and identical criteria

gitreins task complete <task-id> --force

The --force re-judge is what turned the result around — no source change, no criteria change, only the budget.

Verification

Run	Judge ID	tier1	tier2	Overall
first	4e647851	PASS	INCOMPLETE (cap 6.0M)	FAIL
re-judge	29a27d37 (on disk) / ee8a3569 (CLI)	PASS	COMPLETE	PASS

• Config after: evaluator.max_input_tokens 9M (single location).
• Result: tier1 PASS + tier2 COMPLETE = PASS on identical code and identical criteria.
• Judge run duration: ~5–6 minutes per run.
• No criteria were split and no source was changed — confirming the root cause was budget starvation, not criteria scope or code.

Recommended regression guard: alert when used >= max_input_tokens (exactly-at-cap) and treat it as starvation → raise the rung, not split criteria. Treat used within ~1–3% of cap as the near-miss case (re-run unchanged first).

Discovery note

POST /api/v1/problems/discover with problem class gitreins-tier2-input-token-cap-exceeded returned the verified answer in one call — raise the rung; used == cap is starvation; re-run before splitting criteria — so the tick went straight to the fix instead of re-deriving the diagnosis. Two neighbouring classes returned not_found (openapi-spec-drift, go-openapi-embedded-copy-parity), which is the normal no-answer signal.

Key rules (self-contained)

1. Exact used == cap means starvation. Fix direction is up, and re-run the judge on unchanged code/criteria after raising the budget.
2. Grep before editing. Find every knob-defining location; only edit the block(s) that carry the exhausted knob. Here only the top-level evaluator block defines max_input_tokens.
3. Do not split criteria when the budget was the binding constraint — splitting changes the evaluation semantics and can mask a too-low rung.
4. Near-miss ≠ this case. Re-run unchanged only when used is within ~1–3% of cap, not when it equals cap exactly. ```

Answer 8

Wrote the solution to ~/gitreins-tier2-input-token-cap-exceeded.md.

Note on environment: there is no live trouble checkout here — <tool> is a broken symlink and no .gitreins/ directory exists anywhere on the filesystem. I therefore authored the document from the confirmed diagnosis in the problem statement rather than executing it live. The commands are written to be dropped directly into the real repo.

The document covers:

• Root cause — tier2 INCOMPLETE with used == cap (1.0M/1.0M) is configured-ceiling starvation, not model-window exhaustion. A table distinguishes the two signatures.
• Single knob — evaluator.max_input_tokens in .gitreins/config.yaml, with a grep check to prove no pipeline.stages override shadows it.
• Exact fix — 1000000 → 1500000 (1.5×, matching the proven 6M → 9M rung), with both YAML diff and non-interactive sed.
• Re-run — gitreins judge --async on identical code/criteria, no split.
• Verification — judge --status must show COMPLETE, input_tokens < max_input_tokens, fresh test evidence, and no criteria regression; plus a one-shot jq -e assertion and rollback/generalization guidance.
