Verification

Verified base: 18aa9af2b2c26fd114113dd39528a91224801840 (fetched main).

Executed on the implementation worktree after npm ci, npm run build and npm run test:prepare; every check below ran as written in this pass. The built-group projects and the built-CLI checks ran against a dist/ rebuilt after the last source change.

• npm run check:fast: typecheck and lint passed (2 tasks successful).
• npm run format then npm run format:check: all 4028 matched files use the correct format.
• npx knip: ok (exit 0, no unused files, exports or dependencies reported).
• npm run check:ci:tasks: typecheck, lint:built (3730 files, 0 errors), format:check, knip, metadata:check, jscpd (3.35% duplicated lines over 3140 files and 2581 clones, under the 3.5% gate) and the tech-debt marker scan passed (8 tasks, 3 replayed from this worktree's cache).
• npm run docs:check: the six built documentation checks and the README consistency conformance test (5 tests) passed; no tracked generated file changed.
• npx vitest run --project domain --project services (full source group): 312 files, 5412 tests passed, 3 pre-existing skips.
• npx vitest run --project cli-boundary (full project): 111 files; 659 tests passed, 2 pre-existing skips, 8 failed in three files that drive no analysis-view command (closedStdout, commandFinalizationCancellation, javascriptApplicationJsonOutput). Re-run in isolation on this worktree the three WASM interrupt cases and the four JavaScript JSON-output cases passed and only closedStdout "stops quietly when the reader closes during streamed JSON" (inspect-sqlite-database) exited 1 instead of 141. The same three files run on a clean export of 18aa9af2 (git archive, fresh npm ci, npm run build, npm run test:prepare, nothing from this slice) reproduced exactly that one failure and passed the other 16, so none of the eight is attributable to this slice and none was changed here.
• npx vitest run --project mcp-boundary (full project): 153 files passed, 2 pre-existing file skips; 901 tests passed, 7 pre-existing skips, no failures.
• npx vitest run --project acceptance (full project): 123 files passed, 1 pre-existing file skip; 608 tests passed, 13 pre-existing skips, no failures.
• Built CLI end-to-end on the 28-record Grafana-shaped capture: inspect-web-network-capture ... har --format json then inspect-analysis-view with environment-manifest, with and without the three opt-in rules, and with api-surface, twice each. Without rules the 22 tool templates plus the 3 primary-origin exclusions equal the 25 api-surface groups on that origin and every path_template equals its api_surface_template; with rules /api/dashboards/uid/{uid}, /api/folders/{uid} (observed values fg1jo91e57e2ob and general, records 12 and 13), /api/plugins/{plugin_id}/settings and /api/datasources/uid/{uid}/health appear across 19 tools with 13 templated groups; normalized_result and evidence_id are identical across the two runs of each view; records carry only pointer keys; no recorded body or query value appears; three unknowns and view_digest are present; confidence is inferred with authority historical-reference.
• Built CLI on the same capture extended with GET /api/teams/search and GET /api/teams/mine (30 records), all three rules selected: /api/teams/{numeric} keeps observed value 1 only and get_teams_search and get_teams_mine stay their own tools; 21 tools, 13 templated groups.

Independent review

Findings repaired at their owning boundary:

1. A __proto__ key in a recorded JSON body became a prototype rather than an own property, and the schema clone then dropped it silently. The manifest accumulator builds body shapes with Object.fromEntries, omits that key and states the omission as a limitation; a domain regression covers it.
2. The contract example carried a readonly tuple that the mutable JSON example type rejects; the example keeps a literal-typed mutable tuple.
3. Folding a literal sibling into an already templated position took the parts of the earliest group, so a literal recorded before the token kept its literal, dropped the parameter and claimed the token's record under a template it does not match. mergeGroups now takes the templated group as the shape for parts while the earliest group still names api_surface_template, body_shape and record order; a domain regression with the literal recorded first covers it.
4. The request-body parse accepted text/plain and text/markdown bodies; it accepts only application/json and application/*+json, and the capture guide states the earliest-record rule; a domain test covers both media types.
5. A repeated entry in template_rules was accepted, echoed and hashed into view_digest while the accumulator deduplicated it; the request schema refuses repeats with template_rules must not repeat a rule.
6. The sibling-variance fold-in absorbed a non-conforming literal into a parameter produced by one of the four format rules, so /api/teams/mine became an observed value of /api/teams/{numeric} and the published rule no longer described every observed value. Fold-in is restricted to parameters produced by the opt-in rules; literal siblings of a format-rule parameter stay their own tools or merge among themselves under sibling-variance only when identifier-like. A domain test with /api/teams/1, /api/teams/2, /api/teams/search and /api/teams/mine, the capture guide and the spec state the rule; the built-CLI check above exercises it.

Hosted lane

• real-web-network-captures (hosted ubuntu-24.04, workflow run https://github.com/earakely-scale/rea/actions/runs/39097105064 on the fork at 2d95597f) passed with the manifest block of scripts/verify-web-network-captures.mjs executed against the lane's producer and mitmproxy captures. The first run at 61d35369 failed only in that block: the refusal check stringified the whole MCP result, so the declared [ literal matched the result envelope; the follow-up compares the parsed refusal as the api-surface branch does.

Token usage and full process-family peak are unmeasured. Local real-tool verification ran on macOS arm64; the hosted Linux lane result is recorded above.

Automated review findings on the PR (2026-10-18)

Codex and Greptile left seven inline findings on morluto/rea#4954 at b6d18d23; each was checked against the code and addressed in one follow-up commit, with a regression test where the behaviour is observable:

• Body shapes walked nested values (both reviewers, P1): #bodyShape passed the text to inferJsonShape, whose per-node path copies grow with the square of depth, so a small deeply nested body could exceed the budget it had reserved. The reader now parses once and reads top-level key types from the parsed object; a test feeds a 2,500-level nested body and gets the four top-level types back.
• Literal route parts were not admitted (Codex, P2): a path of many short literal segments materialized one part object per segment without a charge. Every route part is now charged before the group is created; a test shows a 5,000-segment path refused under a 1 MiB budget while a 100-segment path is retained.
• sibling-variance rebuilt a key over the whole route at every position (Greptile, P1): routes longer than 32 segments are no longer compared, the manifest states it in a limitation, and a test shows two 39-segment siblings left unmerged beside a merged short pair.
• after-uid-literal templated stop words (Greptile, P1): the rule now skips them; a test keeps /api/items/uid/search literal beside /api/items/uid/{uid}.
• Tool-name suffixes restarted at 2 on every collision (Greptile, P2): the registry keeps the next suffix per base; a test projects 300 dotted literals into get_item and get_item_2 through get_item_300.
• An exclusion row could lose its templated flag when two groups printed the same row (Codex, P2): the flag is now the logical or of both. The scenario needs a literal segment spelled {numeric}, which the WHATWG URL parser percent-encodes in recorded paths, so no capture reaches it; the one-line defence is kept without a test.

Checks after the change: oxfmt --check . clean; tsc --noEmit clean; npm run lint and verify:module-boundaries clean (the complexity warnings on #append predate the change); npx knip no findings; npm run jscpd 3.35 % duplicated lines; scan:todos none; verify:test-discovery 1,580 files once; vitest run over the view, accumulator, JSON-shape and contract example tests 32 passed in 4 files; vitest run over the service, CLI and MCP boundary tests for analysis views 73 passed in 3 files.

A sixth automated finding (Codex) was addressed after the collaborator's merge of main: sibling-variance merged a whole bucket when any one literal carried a digit, so /api/items/mine could be folded into {item_id}. The rule now partitions the bucket and merges only the identifier-like siblings (each with a digit or colon, or three or more hyphenated names under a plural literal), leaving the other literals as their own tools; with the rule alone the fixture therefore keeps /api/folders/general and /api/folders/fg1jo91e57e2ob separate, while all three rules still fold general into /api/folders/{uid} through the opaque-token parameter. Tests: the new partition case and the updated single-rule table.

Follow-up mixed-cohort regressions reproduced two omissions on dd87f54e with main 8307ea37: two coded siblings prevented three qualifying hyphenated siblings from joining the parameter, and one coded sibling was omitted when three hyphenated siblings merged. Eligibility now belongs to one Set that combines both qualifying cohorts before the minimum group size is checked. The consumer reuses that Set and materializes its merge order once. Three cases cover both omissions and preserve the three-hyphen minimum when only two hyphenated siblings accompany coded identifiers; mine and search remain literal and every source record remains represented.
