+## Benchmarks
+
+Fair headline: C `-O2` vs Zig `ReleaseSafe` (Linux Docker aarch64; governor
+unavailable). Safe interp arithmetic p99 about **1.03%** slower (8209 vs 8125 ns).
+Protocol and full distributions: `bench/methodology.md`, `bench/results.json`,
+`bench/plots/`.
+
+---
+
+## Limitations
+
+- Repo must be **public** at submission (organizer rule). Confirm visibility
+ before the form.
+- Demo **video** is a human recording from `docs/demo-script.md`; SVG segments
+ are committed under `docs/demo/`.
+- Benches are container measurements, not bare-metal locked-CPU runs.
+- Write-up side quest closes 2026-08-10 18:00 UTC (`docs/writeup.md` draft).
+
+---
+
+## Judge path
+
+1. `docker compose up --build verify`
+2. `docs/judge-quickstart.md`
+3. `docs/evidence/self-audit.md`
+4. Green CI on `main`
+
+Self-audit and freeze notes: `docs/evidence/self-audit.md`.

+
+Required deliverable 07 is a live screen recording of the original suite
+passing against the port. This file is the shot list and narration. SVG
+terminal captures of each segment are already committed under `docs/demo/`
+(generated by `docs/demo/render_svg.py` from real command transcripts in
+`docs/demo/segments/`).
+
+**Outstanding human action:** record the MP4 from this script and upload it
+with the submission form **before 2026-08-03 18:00 UTC**.
+

+
+Optional: re-record with `asciinema rec` (installed on the audit host) and

+
+## Timed shot list (total ~4:30)
+
+### 0:00-0:25 Hashes first
+
+Show `bash scripts/verify-original-hashes.sh` and
+`bash scripts/fetch-upstream-and-diff.sh` both OK.
+**Say:** "These are the upstream tests, unmodified, checked live against the
+pin."
+
+### 0:25-1:10 Default suite live
+
+`bash scripts/run-original-suite.sh default`
+Leave `ALL TESTS PASSED (4930/4930)` on screen for two seconds.
+**Say:** "Same smoke.c, linked to the Zig static library."
+
+### 1:10-1:50 Four configurations
+
+Show the four OK lines: 4930, 4924, 4934, 4928.
+**Say:** "All four compile-flag combinations. Counts are configuration
+invariants, not host noise."
+
+### 1:50-2:40 Nest contrast (the legible moment)
+
+Split or sequential:
+1. Quote C first-crash depths from the repro log (Darwin 23764 / Docker 17471).
+2. Run or show `zig_abi te_compile depth=3000 -> NULL err=-1`.
+**Say:** "Identical class of input. C exhausts the stack. The port returns a
+bounded error."
+
+### 2:40-3:20 Differential fuzz
+
+Show `fuzz/log.txt` with `seconds: 60` and `divergences: 0`.
+**Say:** "Sixty seconds is a duration claim. Enumeration and coverage are how
+we argue reach. The log still clears the bonus bar."
+
+### 3:20-4:00 Escape-hatch gate
+
+Show planted hatch outside `c_abi.zig` failing (`pass: False`, ILLEGAL lines),
+then restore (`pass: True`, total 16).
+**Say:** "A gate that can fail is a gate that exists."
+
+### 4:00-4:30 One command
+
+Show README first screen and/or `docker compose up --build verify` ending in
+`VERIFY OK`.
+**Say:** "One command. Scorecard written from artifacts."
+
+End black.

+# Write-up draft (side quest)
+
+Publishable draft for the Write-Up side quest ($100 x 3). Closing
+**2026-08-10 18:00 UTC**. Polish and post after code freeze; this file is the
+technical substance.
+
+Tag when publishing: Hackathon Raptors.
+
+---
+
+## What we ported
+
+Track G: [codeplea/tinyexpr](https://github.com/codeplea/tinyexpr) (C) to Zig
+0.16.0, pin `4a7456e2eab88b4c76053c1c4157639ccb930e2b`. The original
+`smoke.c` / `minctest.h` stay byte-identical and link the Zig static library
+through the upstream header. Four flag combinations pass at 4930 / 4924 /
+4934 / 4928.
+
+## The plan that measurement destroyed
+
+Early notes claimed `fac(21)` wraps `unsigned long` to a wrong finite, so the
+port should use wrapping mul for bit-equivalence. On the pin, `fac(21)` returns
+`+inf` (bits `0x7ff0000000000000`) because of an existing
+`ULONG_MAX / result` guard. We threw away the wrap story. Default behaviour
+matches the INF sentinel; an optional `-Dfix-fac-overflow` is a separate,
+documented divergence.
+
+That mistake is useful: a confident plan is not evidence. Opening the C and
+timing one call beat a page of speculation.
+
+## The veneer we had to tear out
+
+The first architecture review found what looked like an idiomatic Zig layer
+sitting on top of a second, private recursive-descent parser inside the ABI
+shim. The native AST could not even represent user functions the way smoke
+needed. We unified on one `Parser(Builder)` and deleted the private grammar.
+Sign collapsing in `power()` had to match C exactly or `TE_POW_FROM_RIGHT`
+peeled the wrong nodes. That bug nearly shipped as "Zig is wrong about
+associativity" when it was really "we forgot how C folds unary minuses."
+
+## Why the port binds platform libm
+
+Differential equivalence compares `f64` as `u64` bits. Sampled glibc vs
+`std.math` on the same grids: `sin` / `cos` / `tan` agreed on every sample we
+ran; `asin` differed on about 93.6% of 26109 samples; `acos` about 93.8%.
+A bit-exact port that calls `std.math` for those would fail fuzz for a reason
+that has nothing to do with the parser. So every transcendental goes through
+platform libm (D004).
+
+## Escape hatches we could not remove
+
+Zig has no `unsafe` keyword. We still need pointer casts to speak the C
+`te_expr` layout, including the fake flexible array. Count: 16, all in
+`src/c_abi.zig`, threshold 20, CI fails if one escapes the file. We
+demonstrated the gate failing by planting a cast in `src/root.zig` and
+watching `pass: False`. That is the Zero Unsafe bonus under an operational
+definition, not a claim that FFI is free.
+
+## The benchmark that did not flatter us
+
+Fair headline: C `-O2` vs Zig `ReleaseSafe` on a Linux aarch64 Docker host
+(governor unavailable; confounders named). Safe `te_interp` arithmetic p99 was
+8209 ns against C at 8125 ns (about 1.03% slower). Startup warm p50 and RSS
+were higher for Safe. We still headline Safe because the checks are part of
+the product. Reporting only ReleaseFast would have been the dishonesty the
+event exists to punish.
+
+## Sixty seconds measures duration
+
+`fuzz/log.txt` shows 60.0 seconds and 0 divergences (48.5M executions on the
+certifying host). That clears the bonus bar. It does not measure reach. Reach
+is the original suite, coverage with missed-branch reasons, exhaustive
+enumeration (11505 inputs, 0 divergences at the completed bound), and malloc
+ordinal injection (honest negative for Track G allocator-misuse). Duration is
+cheap. Reach is the work.
+
+## Bugs we filed without lying about novelty
+
+Issue 136 (nest stack overflow) was already open. We reproduced it and
+commented with host-specific thresholds. Signed-char ctype was already
+issue 105; we confirmed and sent a cast PR. Novel filings:
+`next_token` external linkage (issue 141, PR 143) and locale/`strtod`
+correctness after `setlocale` (issue 142). The locale hang theory did not
+reproduce. Allocator-misuse as a C crash under fault injection: not found.
+
+## What we would take back
+
+Shipping the forked parser even briefly. It burned review trust and hours.
+Also: any sentence that treated a plan probe as a measured fact.
+
+## One command
+
