Follow-up to #219, now that content-header detection has shipped as v0.46.0.

Ledger updated

The 2026-08-20 entry's shipped table gains v0.46.0 (#220, content-header generated detection, upstream #1500 + 57e0854), and the header's release range plus the entry title move from four tiers through v0.45.0 to five tiers through v0.46.0.

A defect recorded ahead of its port

The still-open section previously said the explore epic and content-header detection were both unshipped. One of those is now done, and the review of the other surfaced something worth writing down rather than leaving in a plan file:

engine.rs's whole-file rule returns a complete section before any budget, ceiling, or focus logic exists — and its two thresholds are independent:

const WHOLE_FILE_MAX_LINES: usize = 220;
let whole_file_max_chars = budget.max_chars_per_file * 3;
if total_lines <= WHOLE_FILE_MAX_LINES && content.len() <= whole_file_max_chars

So a file can pass the line gate, fail the character gate, fall through to clustering, and then be rejected whole. Measured:

src/big.ts   63 lines / 19,245 bytes, holds the named target
$ codegraph explore namedTarget
  615 bytes, 0 `####` sections, 0 occurrences of the definition

615 bytes with zero sections is byte-identical to the original CG-38 defect, reached by a different route — and a MIN_WINDOW focus slice would have fit comfortably. It matters because a fix that only funds headroom inside the clustering path leaves this hole open, and a test that oversizes only line count will never reach it.

Recording it here means the next person to touch explore budgeting finds it without re-deriving it, whether or not the current Tier 5 plan lands.

Docs only: one file, oxfmt idempotent, tracked parity unchanged at 1.5.0.
