+# Memory Ceiling Gate Implementation (bf-1g1fd)
+
+## Summary
+
+Implemented a Tier-1 memory ceiling gate that enforces RSS budgets for PDF extraction, analogous to cargo-bloat for binary size. The gate samples peak RSS while extracting perf + malformed corpora and fails the build if any document exceeds its budget.
+
+## Changes Made
+
+### 1. Expanded xtask memory-ceiling command
+
+**File:** `xtask/src/main.rs`
+
+- Added support for three memory budget categories:
+ - Buffered 100-page vector PDF: 512 MB
+ - Streaming/NDJSON mode (any page count): 256 MB
+ - Adversarial fixtures: 1 GB hard ceiling
+- Added streaming mode testing with `--format ndjson`
+- Generates JSON report (`memory-report.json`) with:
+ - Per-document results (peak RSS, duration, budget, pass/fail)
+ - Summary statistics
+ - Commit SHA for historical tracking
+- Added `MemoryTestResult`, `MemoryReport`, `MemoryBudgetJson`, `MemorySummary` structs
+
+**File:** `xtask/Cargo.toml`
+
+- Added `serde_json` dependency for JSON output
+- Added `humantime` dependency for timestamp formatting
+
+### 2. Updated CI memory-ceiling template
+
+**File:** `.ci/argo-workflows/pdftract-ci.yaml`
+
+- Added cgroup MemoryMax enforcement (1.5 GB cap) for clean failure mode
+- Supports both cgroup v2 (preferred) and cgroup v1
+- Falls back gracefully when cgroup unavailable
+- Uses xtask-generated `memory-report.json` for artifact upload
+- Shows summary from report in CI logs
+
+### 3. Updated fuzz workflow with cgroup enforcement
+
+**File:** `.ci/argo-workflows/pdftract-nightly-fuzz.yaml`
+
+- Added cgroup MemoryMax enforcement (1.5 GB cap) to fuzz-target template
+- Layered memory enforcement:
+ - Cgroup MemoryMax: 1536 MB (hard ceiling on entire fuzz run)
+ - Libfuzzer `-rss_limit_mb=1024` (per-execution RSS cap)
+ - Libfuzzer `-malloc_limit_mb=1024` (total malloc cap)
+- Supports both cgroup v2 (preferred) and cgroup v1
+- Falls back to libfuzzer limits when cgroup unavailable
+
+## Acceptance Criteria
+
+### PASS
+
+- [x] Harness samples peak RSS while extracting perf + malformed corpora
+- [x] Build fails if any document exceeds its memory budget
+- [x] Test suite runs under cgroup MemoryMax cap (1.5 GB)
+- [x] Fuzz suite runs under cgroup MemoryMax cap (1.5 GB)
+- [x] Libfuzzer `-rss_limit_mb=1024` and `-malloc_limit_mb=1024` set
+- [x] Memory targets are now Tier-1 gates
+
+### WARN (environmental issues)
+
+None - all infrastructure (cgroups, libfuzzer limits) is standard CI environment
+
+### FAIL
+
+None
+
+## Implementation Notes
+
+### Cgroup Support
+
+The implementation supports both cgroup v2 (preferred) and cgroup v1:
+- Cgroup v2: Uses `/sys/fs/cgroup/` with `memory.max` controller
+- Cgroup v1: Uses `/sys/fs/cgroup/memory/` with `memory.limit_in_bytes`
+- Falls back to libfuzzer limits when cgroup unavailable
+
+### Memory Budgets
+
+Per plan.md line 72-80:
+
+| Category | Budget | Measurement |
+|----------|--------|-------------|
+| Peak RSS, 100-page vector PDF (buffered mode) | < 512 MB | `tests/fixtures/perf/` |
+| Peak RSS, streaming/NDJSON mode (any page count) | < 256 MB | `tests/fixtures/perf/` with `--format ndjson` |
+| Peak RSS, adversarial fixtures | < 1 GB | `tests/fixtures/malformed/` |
+
+### RSS Sampling
+
+The xtask `measure_extraction` function:
+- Spawns pdftract as a child process
+- Samples `/proc/[pid]/status` every 10 ms for `VmRSS` field
+- Tracks peak RSS across the extraction run
+- Works on Linux; falls back to time-only measurement on other platforms
+
+### JSON Report Format
+
+The `memory-report.json` artifact includes:
+```json
+{
+ "timestamp": "2026-05-23T12:34:56Z",
+ "commit_sha": "abc123...",
+ "budgets": {
+ "buffered_100_page_mb": 512,
+ "streaming_any_mb": 256,
+ "adversarial_hard_cap_mb": 1024
+ },
+ "results": [
+ {
+ "file_name": "example.pdf",
+ "category": "buffered",
+ "peak_rss_mb": 123,
+ "duration_ms": 456,
+ "budget_mb": 512,
+ "passed": true,

+ }
+ ],
+ "summary": {
+ "total_tests": 10,
+ "passed": 10,
+ "failed": 0,
+ "all_passed": true
+ }
+}
+```
+
+## Testing
+
+To test locally:
+```bash
+# Run memory ceiling tests
+cargo run --release --bin xtask -- memory-ceiling
+
+# Run fuzz tests with memory limits
+bash scripts/run-fuzz-with-limits.sh [target]
+```
