+# Integer validator allocation after MCP materialization
+
+Issue #6236; PR #4360. Linux x64, 2026-10-22.
+
+<!-- BEGIN:allocation-report:provenance -->
+
+Baseline `main@4a4bbab3c337701febeb6b532ace49041c4876e0`; candidate `461f342c71a72ef2be60912391df2393aa4e2ea3`. This is a pinned comparison.
+
+In separate inspector/forced-GC diagnostics, retained REA V8 heap decreases by about 9.6 MiB. The three-pair ranges do not overlap in either profile. Inspector perturbation is included. Normal task timing, CPU and peak memory are reported separately; these observations do not establish a general latency or peak-memory reduction.
+
+<!-- END:allocation-report:provenance -->
+
+Directory discovery uses recorded advertisements after #4424; this study separates it from completed tasks that materialize canonical handlers. Context is unchanged.
+
+## Change and compatibility
+
+Replace 1,247 argument-free `z.number().int()` constructions with `z.int()` across 175 existing source files. Keep current shared schema owners, refinements, bounds, defaults and metadata. AST-token comparison against the baseline, after normalizing this construction and formatting, is equal for every touched source file. No new tools, provider effects, caches or response contracts.
+
+The locked Zod 4.4.3 chained form retains a `ZodNumber` with a separate `ZodNumberFormat` check; direct construction uses the format itself. Incur 0.6.1 coerces argv strings only for `ZodNumber`. Existing CLI declarations and shared-input exceptions therefore retain the chained form. The actual compiled CLI registers 160 leaf commands; 104 numeric argument/option fields have identical results/errors in 974 installed-Incur parser cases across both runtimes, each field with an accepted probe. Fields are isolated from unrelated required options and no handlers are invoked. This is consumer-boundary coverage, not a real-engine claim.
+
+Seven dependency-boundary variants match parsed values and complete error issues for 126 cases, including fractions, nonfinite values, strings/null/undefined and unsafe integers; 14 JSON Schema projections match in draft-07/draft-2020-12. Actual SDK advertisements match byte-for-byte in both profiles before/after materialization and across roles.
+
+## Tasks, artifacts and bounds
+
+Reuse the shared SDK task driver and independent ELF/section/zlib/JSON oracles from [the catalog study](mcp-input-catalog.md): official Alpine v3.21 x86_64 ripgrep 14.1.1-r0 and Zellij 0.40.0-r0. All 42/422 packages and 88/1,063 edges match the independent oracles. Select serde name/version/kind, repeat exact retained-parent reads twice, verify a canonical negative-offset refusal, export/check complete Evidence and confirm the unchanged directory. `kind: null` stays unknown. Targets are not executed; dependency presence does not establish runtime use. Acquisition URLs, archive/executable/oracle hashes and complete answers are in [the receipts](mcp-integer-allocation.json). Previously acquired public bytes are rehashed, not redownloaded.
+
+Normal cohort: three alternating baseline/candidate pairs for each task × cold/warm server compile cache × default compact/full inputs: 72 trials, plus four excluded full-task warm priming runs. Separate diagnostic cohort: three alternating pairs per profile, cold Zellij tasks, 12 trials. All pass, with identical complete parent IDs/hashes and answers.
+
+Node 24.18.0/npm 11.16.0; fresh client/server and HOME per trial, driver compile cache disabled. Each trial is serial, pinned to one CPU, 4 GiB hard/3 GiB early stop, no swap, at most 192 tasks. Before/after checks bind clean source, all compiled JS/JSON assets (1,990 baseline / 1,990 candidate files), scripts and manifests; producer and resource-observer hashes are also bound. No OOM, resource stop or leftover payload processes. Whole-family measurements include SDK validation, extra calls, source/compiled audits and oracle checking; kernel peak includes file cache. Build/acquisition/oracle generation and priming are excluded. Warm uses a populated role/profile-specific Node cache; hit rate and OS page cache are unmeasured, and audits warm compiled-file pages.
+
+## Normal task costs
+
+Medians, baseline → candidate; all ranges are in the JSON. No inspector or diagnostic GC runs in this cohort.

+
+Full-profile warm Zellij is slower than its cold condition in both roles in this cohort. Cache hit rate and the cause of this observation are unmeasured, and cold/warm groups run sequentially. These timings support neither a general cache speedup nor a causal regression attribution.
+
+## Separate retained-heap diagnostics
+
+The same completed SDK task launches only its owned REA process with `--inspect=127.0.0.1:0`. Four CDP calls verify the owned transport PID, read heap, force GC and read heap again. The endpoint comes from that child’s stderr; the PID is a cross-check of the owned endpoint, not sole ownership proof. The inspector socket closes before MCP shutdown. These V8 values include inspector perturbation and exclude the client; diagnostic wall/CPU/family peaks include inspector and forced-GC overhead and are not normal-task timing results.

+A mismatched PID is rejected; removing only that guard makes the negative oracle fail. Both connections in that check use the same owned REA endpoint, with no foreign-process attachment. Aggregation rejects diagnostic GC in a normal trial. Historical #4424 receipt reaggregation preserves previous metrics and adds the separately reported SDK-span fields; its aggregator source hash changes.

+Question, explicit recipe, server instructions, one complete name/description/input-schema directory, every tool argument and text reply, plus prompt directory for discovery. This projection assumes the client retains a single unchanged directory. Raw catalog result costs include every observed tools/list result separately, with output schemas and without JSON-RPC envelopes. SDK initialization/framing, reasoning and actual model usage are unmeasured. The analysis task includes retained-read, rejection, export/oracle and post-materialization directory checks.

+
+## Validation and reproduction
+
+- Both runtime builds and all six static checks plus architecture guards pass. Before the final main synchronization, 5,972 source/contract/public CLI/MCP tests pass across 323 files; four skip for unavailable/guarded coverage. After synchronization, both builds/static checks repeat successfully, 77 affected producer and CLI/MCP tests pass, and all 974 registered numeric-parameter parser cases match again. Includes real SQLite CLI/MCP record/column selection and JavaScript heap/deadline preservation. A first direct schema-validity invocation lacked generated catalog metadata; the supported focused entry generates it and all 15 cases pass. A later affected-test invocation selected two nonexistent paths; the corrected three-file producer/consumer run is the 77-case result above. Neither setup failure was counted as a passing test, and no production or timeout change was needed.
+- All 84 measured tasks and four warm priming tasks pass independent oracles, canonical refusal, parent/directory identity and owned cleanup checks. This does not verify external Hopper/Ghidra/IDA, Android devices, all providers or foreign OS behavior. The earlier macOS numbers in #4360 describe a different revision/platform and are not combined with these results.
+
+Build the pinned baseline/candidate in separate clean worktrees with the locked toolchain. Use the candidate’s producer scripts for both roles. `measurement_inputs` in the JSON records the complete matrix, questions/recipes, runtime bindings and producer hashes; extract it unchanged as the bindings file. Historical receipts require their matching producer revision. One normal task:
+
+```bash
+NODE_DISABLE_COMPILE_CACHE=1 node experiments/analysis-efficiency/mcp-input-catalog.mjs \
+  --runtime "$CANDIDATE_RUNTIME" --bindings "$MEASUREMENT_INPUTS" --role candidate \
+  --artifact "$RIPGREP_BINARY" --oracle "$RIPGREP_ORACLE" \
+  --output "$NEW_CASE_DIRECTORY" --profile default --phase analysis --cache cold
+```
+
+Run each task through `resource-run.py --observe-payload-exit --` to obtain whole-family counters. For warm runs replace `--cache cold` with `--cache warm --cache-root <role/profile cache>` after one complete priming task. For the separate Zellij diagnostic tasks add `--diagnostic-heap` and use cold cache. Keep their case names/logs aligned with `measurement_inputs`; aggregate both cohorts with:
+
+```bash
+python experiments/analysis-efficiency/mcp-startup-costs.py "$RECEIPT_ROOT" \
+  --output mcp-integer-allocation.json
+```
+
+The aggregator requires the recorded tiktoken version, exact catalog/parent/runtime/producer/guard identities, clean source, successful payload cleanup and matching matrix coverage. Default driver behavior continues without an inspector; the heap flag is confined to the experiment.
+
+Regenerate or verify every numerical section directly from the committed JSON:
+
+```bash
+node experiments/analysis-efficiency/mcp-integer-report.mjs
+node experiments/analysis-efficiency/mcp-integer-report.mjs --check
+```
+
+The documentation conformance gate checks current receipts, rejects stale normal/heap tables, and refuses missing producer markers without writing.
