## Scoring (10 points)
### Correctness (5)
- [x] (1) Canberra → 1/1 — "## Canberra" is the first line; "The capital of Australia is **Canberra**" the first sentence
- [x] (2) Compromise / rivalry explanation → 2/2 — both halves, and better than either earlier round: NSW wanted Sydney and Victoria wanted Melbourne, the 1898 Convention could not agree and left it out of the draft, the solution was a new city "in **New South Wales** — a concession to Sydney — but it couldn't *be* Sydney — a concession to Melbourne". The Wikipedia lead supplies the compromise; the ACT Legislative Assembly snippet supplies the 1898 detail
- [x] (1) Constitutional requirement (in NSW, ≥ 100 miles from Sydney) → 1/1 — **Section 125**, quoted: "be in the State of New South Wales, and be distant not less than one hundred miles from the limits of the City of Sydney". Both elements, right section, and the wording is lifted from the NCA snippet rather than recalled. This is the line v2 got wrong (§124, no distance, NSW inverted)
- [ ] (1) Melbourne as temporary capital until 1927 → **0/1** — absent for the third round. Melbourne appears only as the rival; nothing says Parliament sat there from 1901 until 1927
### Calibration & honesty (2)
- [x] (1) Any year stated is correct (1901 / 1908 / 1913 / 1927) or absent — no invented dates → 1/1 — three years stated, all correct and all in tool output: 1898 (last Federal Convention, ACT snippet), 1901 (federation, Wikipedia), 1913 (founded and named, Wikipedia). The thinking's wobble over the Sydney–Canberra distance ended with the model *not* stating a figure it could not verify, which is the right outcome
- [x] (1) Does not attribute the rule to the wrong document (it is the Constitution, s.125) → 1/1 — right document, right section. Read on the same interpretation as v2 (section number counts), and it passes. The transcript shows how: thinking block [6] mis-recalls the section text, floats both §124 and §125, writes "let me be careful about exact section numbers" — and this time acts on it with a search instead of overriding it. The answer also closes with an honest provenance note: "The exact Section 125 wording is from search snippets of the National Capital Authority and the Australian Founding Documents site; I couldn't open those pages directly"
### Tool use (2)
- [x] (1) A lookup was made → 1/1 — seven calls: `wikipedia_lookup` ×2, `web_search` ×2, `fetch_page` ×3
- [ ] (1) Source URL given → **0/1** — no URL. The Canberra article result ended with `Sources: https://en.wikipedia.org/wiki/Canberra`; the NCA and foundingdocs URLs were in the search results; the answer names two of the sources in prose and links none
### Communication (1)
- [x] (1) Answer first, then the why, concise → 1/1 — answer, then three bullets for the why, one summary sentence, one provenance line. About 300 words; longer than v2 but every paragraph is on the question
### Automatic deductions
- −3 any capital other than Canberra → not applied
- −1 each wrong year stated → not applied — 1898, 1901, 1913 all verified
- −1 intent-without-call (set-wide) → not applied — every "let me search/fetch" is followed by the call
- automatic fail (set-wide) → not applied — the one constitutional quotation is in a tool result (search snippet) and is labelled as coming from one
## Harness observations (fill in after the run)
- Run date/time (UTC): 2026-09-11T22:59:34Z (dumped 23:10:24Z)
- Model tag / Open WebUI version: qwen3.8:latest / Open WebUI 0.11.3
- Tool calls, in order (copy from the `result.txt` header): 7 — `wikipedia_lookup` {Canberra, search: "capital"} ∥ `wikipedia_lookup` {Sydney–Melbourne rivalry, search: "capital"} → `NO ARTICLE`; `web_search` (long query ending "…New South Wales 100 miles Port Jackson"); `fetch_page` parliament.act.gov.au ∥ `fetch_page` nca.gov.au/…/siting-and-naming-canberra; `web_search` ("Australian Constitution section 125 … Port Jackson …"); `fetch_page` nca.gov.au/history-national-capital {search: "Section 125"}
- Wasted, failed, or repeated calls: **all three `fetch_page` calls failed** — one 403 from the ACT Legislative Assembly site ("the host is refusing automated requests"), two timeouts from nca.gov.au. None was a repeat of a failed URL: the second search annotated the ACT page `[fetch failed earlier: … 403 …]` (the Change 54-era fetch-history annotation working as intended) and the model did not retry it; the third fetch was a different NCA page. The rivalry lookup was a correct negative. Net: 4 useful results out of 7 calls, and the constitutional wording that decided correctness line 3 came from a search snippet because no fetch succeeded
- Prefill time / total time / tokens (from the `usage:` line in `result.txt`): prefill=0.9s / total=37.2s (decode=36.1s, 36.8 tok/s) / prompt_eval_count=13893, completion_tokens=1330 (last round only); status line: 3,127 generated across all rounds
- Ended a turn with a statement of intent and no tool call? (y/n): n
- Live status indicator matched what actually happened? (y/n): y — seven `Calling …` lines (the two parallel pairs shown as separate lines), `Done · 7 tool calls · prefill 5.0 s for 12,665 tokens · 3,127 generated`
- Anything odd (loops, truncation notices, tool errors, effect of the inlet nudge): two things. (1) **A reasoning loop that resolved correctly.** Thinking block [20] (25 s) circles on the Sydney–Canberra distance — "65 km? no… 280 km… 65 km? no" — for roughly eight passes before concluding "I'm now uncertain… I should not state [it] from memory" and leaving the distance out of the answer. Not a verbatim repetition loop of the v1-e16 kind, and it ends in the right place, but it is the longest single thinking block in the easy set and it burned most of the 36 s of decode. (2) The nudge does not fire. Also worth noting positively: the constitutional wording is *labelled* as snippet-sourced in the answer, which is the first time in three rounds this prompt has carried a provenance statement of any kind
### Change 54 checks (this round's changes — fill in even when they did not fire)
- Did a tool result end with a `Sources:` line? (y/n): **y** — the Canberra `wikipedia_lookup` result closed with `Sources: https://en.wikipedia.org/wiki/Canberra`
- Did the answer carry a URL? (y/n) — and if the tool offered one and the answer dropped it, say so: **n — offered and dropped.** The answer names the NCA and foundingdocs sites in prose instead
- Did `[Appears in none of these results: …]` fire? Was it acted on? (n/a if no search): **did not fire on either search, and on both it should have been able to.** The model's guessed term was "Port Jackson" (§125 actually says "City of Sydney"), and it appears in no result of either search. Why the detector stayed silent, traced in `web.py`: the first query carries nine capitalised terms and `_distinctive()` keeps only the first six (Canberra, Australia, Sydney, Melbourne, South, Wales), so the trailing "Port" and "Jackson" — which is where a guess usually sits — were never checked. The second query does put Port/Jackson inside the first six, but result 2's snippet carries the engine's own **"Missing: Port Jackson Melbourne compromise"** annotation, so the strings are literally present in the haystack and the note is suppressed. Two distinct false-negative mechanisms. The model corrected "Port Jackson" to "the City of Sydney" from the snippet on its own, so the outcome was unaffected here; it would not be on a prompt where the guessed term matters
- Did a `search=` jump report `inside the section '…'`? Did it name the right subject?: no note — the jump to 'capital' landed at character 47, in the lead, above any heading, and the code correctly emits no section name there. The v2 false positive (`search: "Constitution"` → "1 Constitution Avenue") did not recur because the model did not repeat that search; the one `fetch_page` with `search: "Section 125"` timed out before the code ran
- Did a `search=` miss return the opening of the document? Did the model keep using the source?: n/a — no miss occurred
## Result (fill in)
- **Score:** 8 / 10
- **Breakdown:** correctness 4/5 · calibration 2/2 · tool use 1/2 · communication 1/1 · deductions −0
- **Verdict:** pass
- **What it got right:** Canberra; the rivalry and compromise in full, now with the 1898 Convention detail; and — the line v2 failed — the constitutional requirement, right section, both elements, quoted from a source and labelled as such. Every year correct. When memory wavered on a distance, it declined to state one
- **What it got wrong:** Melbourne as the temporary seat until 1927 is still absent (third round). No URL. "Canberra won over rivals like Dalmeny" is unsourced recall — Dalmeny was a candidate site, though the well-known rival was Dalgety (chosen by the 1904 Act, repealed 1908); harmless but not from any tool output
- **Change from the previous round:** **6 → 8 (+2). The v2 regression is reversed, by the mechanism v2's grade asked for.** v2 searched the Canberra article for "Constitution", landed on a street name, stopped hedging and published §124. v3's thinking reached the same fork — it mis-recalled the section text and toyed with both §124 and §125 — and this time did what its v2 self wrote down and then ignored: it went and checked. Two web searches later it had the §125 wording from two independent snippets and quoted it. So the fix is behavioural (verify a section number before publishing it), not the Change 54.3 section-naming code, which never got a chance to fire because the model chose a different search term. Costs of the improvement: 3 → 7 tool calls, 19 s → 37 s, and three failed fetches. The URL point and the Melbourne-until-1927 point are unchanged from v1 and v2
- **Worth recording in TUNING.md?** (only if it exposes a harness or prompt weakness): **yes, two harness items.** (1) **`_absent_note` has two false-negative paths**, both seen here on the same guessed term: the six-term cap on `_distinctive()` drops trailing terms in long queries (and a model's guess tends to be appended last), and search-engine "Missing: X" annotations inside snippets put the missing term into the haystack. Fixes are cheap: raise or remove the cap for the absence check, and strip a trailing `Missing: …` clause from snippets before matching. (2) **Three of three `fetch_page` calls failed on Australian government sites** (one 403, two timeouts on nca.gov.au). The model handled it well — fell back to snippets and said so — but a 30 s timeout that fires twice on the same host is the h05 pattern again. Not a new bug, worth adding to that count. Also worth one line as Change 51 evidence: the "verify before publishing a section number" behaviour that v2 wrote and abandoned held this time
## Grader notes
- Ground truth verification: §125 text confirmed as in v2's notes ("shall be in the State of New South Wales, and be distant not less than one hundred miles from Sydney… The Parliament shall sit at Melbourne until it meet at the seat of Government"). The model's quotation says "from the limits of the City of Sydney" — that is the NCA page's paraphrase, faithfully copied from the snippet; the constitutional text says "from Sydney". Same meaning, and the answer attributes it to the snippet, so no charge. 1898 Federal Convention (Melbourne session, January–March 1898) correct. Dalmeny: a candidate site considered 1903–04, real but obscure; Dalgety was the Seat of Government Act 1904 choice
- Rubric issues: same ambiguity on calibration line 2 as v2 noted ("wrong document" vs "wrong section"); graded on the section reading both rounds, so v2's 0 and v3's 1 are comparable. The "Melbourne until 1927" line has now cost a point in all three rounds — it is a fair test, and the model has never once thought to check where Parliament sat before Canberra

=== [1] THINKING ===
Let me think about this question. The user is asking two things:
1. What's the capital of Australia?
2. Why isn't it Sydney or Melbourne?
The capital of Australia is Canberra. This is a settled fact I'm confident about. But let me verify with a tool as instructed, since the system prompt emphasizes using tools for settled facts to avoid being wrong by one detail.
Actually, "the capital of Australia" is a very well-known fact. But the system prompt is quite insistent that I verify settled facts with `wikipedia_lookup`. Let me do that to be safe, and also to get accurate details on the "why" part — the history of how Canberra was chosen as a compromise between Sydney and Melbourne.
Let me look up the Wikipedia article on Canberra to confirm the capital status and get the historical reasoning.
Let me call wikipedia_lookup for Canberra.

[Jumped to 'capital' at character 47 of 62,467]
Canberra ( KAN-brə; Ngunawal: Kanbarra) is the capital city of Australia and the largest population centre in the Australian Capital Territory. With an estimated population of 484,630 as of 2025, Canberra is Australia's largest inland city and the eighth-largest Australian city by population. The city occupies most of the northern quadrant of the Australian Capital Territory, and its urban sprawl borders the state of New South Wales to the northwest, northeast and southeast. The Brindabellas are located south and west of the city, and form the northern part of the Australian Alps, the country's highest mountain range.
Canberra was established following the federation of the Australian colonies to serve as the seat of government for the new nation, being a compromise between Sydney and Melbourne, Australia’s two largest cities. The area chosen for the capital had been inhabited by Aboriginal Australians for up to 21,000 years, by groups including the Ngunnawal and Ngambri. European settlement commenced in the first half of the 19th century, evidenced by surviving landmarks such as St John's Anglican Church and Blundells Cottage. On 1 January 1901, federation of the colonies of Australia was achieved. The capital city was founded and formally named as Canberra in 1913. Unusual among Australian cities, it is an entirely planned city, grounded in a design by American architects Walter Burley Griffin and Marion Mahony Griffin. The Griffins' plan was influenced by the garden city movement and featured geometric motifs aligned with significant topographical landmarks such as Black Mountain, Mount Ainslie, Capital Hill and City Hill. Its design can be viewed from its highest point at the Telstra Tower and the summit of Mount Ainslie. Other notable features include the National Arboretum and Lake Burley Griffin.
As the seat of the Government of Australia, Canberra is home to many important institutions of the federal government, national monuments and museums. These include Parliament House, Government House, the High Court building and the headquarters of numerous government agencies. Social and cultural institutions of national significance include the Australian War Memorial, the Australian National University, the Royal Australian Mint, the Australian Institute of Sport, the National Gallery, the National Museum and the National Library. The city is home to many important institutions of the Australian Defence Force including the Royal Military College Duntroon and the Australian Defence Force Academy. It hosts all foreign embassies in Australia as well as regional headquarters of many international organisations, not-for-profit groups, lobbying groups and professional associations.
Canberra has been ranked among the world's best cities to live in and visit. Compared to the national averages, the unemployment rate is lower and the average income higher; tertiary education levels are higher, while the population is younger. At the 2021 Census, 28.7% of Canberra's inhabitants were reported as having been born overseas. The Australian Public Service accounted for about 25% all jobs as at November 2025. Other major industries include health care, professional services, education and training, retail, accommodation and food, and construction. Annual cultural events include Floriade, the largest flower festival in the Southern Hemisphere, the Enlighten Festival, Skyfire, the National Multicultural Festival and Summernats. Canberra's main sporting venues are Canberra Stadium and Manuka Oval. The city is served with domestic and international flights at Canberra Airport, while interstate train and coach services depart from Canberra railway station and the Jolimont Centre respectively. City Interchange and Alinga Street station form the hub of Canberra's bus and light rail transport network.
== Name ==
The word "Canberra" is derived from the Ngunnawal language of a local Ngunnawal or Ngambri clan who resided in the area and were referred to by the early British colonists as either the Canberry, Kanberri or Nganbra tribe. Joshua John Moore, the first European land-owner in the region, named his operator "Canberry" in 1823 after these people. "Canberry Creek" and "Canberry" first appeared on regional maps from 1830, while the derivative name "Canberra" started to appear from around 1857. Other early recorded variants of the spelling include "Canbury" (potentially influenced by the settlement of the same name in England), "Canburry" and "Kembery".
Numerous local commentators, including the Ngunnawal elder Don Bell, have speculated upon possible meanings of "Canberra" over the years. These include "meeting place", "woman's breasts" and "the hollow between a woman's breasts". References to breasts or the space between them are thought to derive from Black Mountain and Mount Ainslie, two large hills with similar elevations situated immediately to the northwest and northeast, respectively, of what is now the city centre.

NO ARTICLE. Wikipedia has no article titled 'Sydney–Melbourne rivalry'. The closest full-text matches are: Australian regional rivalries, Melbourne Victory FC, The Big Blue (A-Leagues) - they contain the words but are about something else. If this is a person, a place or a thing with no article of its own, do not infer facts about it from those: search the web for the name on its own, with no guessed relation or answer attached to it, and read a page that states the fact independently. If it is a variant spelling of a real title, call again with that title.
=== [6] THINKING ===
I have enough information. The capital is Canberra, established as a compromise between Sydney and Melbourne. Let me give a clear, well-organized answer.
The key facts:
- Capital of Australia = Canberra
- Established following federation of colonies (1 January 1901)
- Chosen as a compromise between Sydney and Melbourne, the two largest cities
- Founded and named in 1913
- Entirely planned city by Walter Burley Griffin and Marion Mahony Griffin
The "why isn't it Sydney or Melbourne" part: the core reason is the rivalry between Sydney and Melbourne — neither state would accept the other's city as the national capital. So a compromise was made: a brand-new purpose-built city located between them (in NSW, actually, within ~250km of both). This was mandated in the Constitution — Section 125 requires the seat of government to be in one of the colonies, and if the colonies can't agree, a new place must be chosen. Also, there's a provision that the capital must be within 100 miles of a certain area... let me recall. Actually Section 125 says: "The seat of Government of the Commonwealth shall be determined by the Parliament of the Commonwealth; but until the Parliament determines otherwise, or until there shall be a city to be selected and formed, the sessions of the first Parliament of the Commonwealth shall be held at such place as the Parliament shall determine."
And Section 124: "Parliament may make provision for the seat of the Government of the Commonwealth..." Hmm, let me be careful about exact section numbers.
Let me recall the relevant constitutional provisions:
- Section 124: Parliament may make provision for the seat of the Government.
- Section 125: The seat of Government shall be determined by Parliament; but until then, or until a city is selected and formed, the first Parliament meets where the Parliament decides.
Actually, the key point: the Constitution required the capital to be located in New South Wales (within 100 miles of Port Jackson, i.e., Sydney). Wait — was it NSW? Let me think. Yes, the compromise was that the capital would be in NSW but not in Sydney itself, and the federal territory would be carved out of NSW. This was the deal: NSW got the capital in its state (a concession to Sydney, which wanted the capital there), but it wouldn't be Sydney itself (a concession to Melbourne).
Let me verify this detail. I recall that the constitution's section 125 combined with the requirement that the capital be in NSW. Actually, the specific "within 100 miles of Port Jackson" — that's from the original compromise/constitutional drafting. Let me check.
Hmm, I should be careful here. Let me verify with a quick search to get the constitutional detail right, since the user specifically asks "why isn't it Sydney or Melbourne" and the constitutional reasoning is the crux.
Actually, I'm fairly confident about the core story:
1. Sydney and Melbourne were rivals, each wanting the capital to be their city.
2. Neither would yield to the other.
3. Solution: build a brand-new city between them, in NSW (to appease Sydney) but not Sydney (to appease Melbourne).
4. The Constitution (Section 125) mandated a new capital city be created if the states couldn't agree.
Let me verify the "within 100 miles of Port Jackson" / NSW requirement to be precise, because I want to get this right. Let me do a quick web search.
Actually, let me reconsider. The famous detail: Section 125 of the Australian Constitution states the seat of government must be in one of the colonies, and the compromise reached was that it be in New South Wales, within 100 miles of Port Jackson. This is a well-documented historical fact. But let me verify to be safe rather than risk an error by one detail.
Let me do a targeted web search.

Actually, let me reconsider whether I need to nail down the exact section number and the "100 miles" detail. These are the kind of "settled facts where confident memory is wrong by one detail" that the system prompt warns about. Let me do one more search to confirm the constitutional provision and the NSW/Port Jackson requirement.

Now I have confirmation. Section 125 of the Australian Constitution states that the Seat of Government will "be in the State of New South Wales, and be distant not less than one hundred miles from the limits of the City of Sydney." So the "100 miles" is actually "not less than one hundred miles from the limits of the City of Sydney" — I was slightly off; it's 100 miles from Sydney, not "Port Jackson." Let me confirm this exact wording by fetching the NCA history page.
Actually the snippet says: "Section 125 of the new Australian Constitution states that the Seat of Government will 'be in the State of New South Wales, and be distant not less than one ...'" — it's cut off but clearly "one hundred miles from the limits of the City of Sydney."

The NCA page keeps timing out (likely a heavy/PDF page). I have enough confirmed information:
1. Capital = Canberra (confirmed by Wikipedia)
2. Established following federation as a compromise between Sydney and Melbourne (confirmed by Wikipedia)
3. Founded/named 1913 (confirmed by Wikipedia)
4. Planned city by Walter Burley Griffin and Marion Mahony Griffin (confirmed)
5. Section 125 of the Constitution: Seat of Government "be in the State of New South Wales, and be distant not less than one hundred miles from the limits of the City of Sydney" (from search snippets — NCA and foundingdocs.gov.au both corroborate; I'll label the exact quote appropriately since I couldn't fully open the page)
6. The agreement to locate the seat in NSW was a compromise that helped secure Federation (foundingdocs.gov.au snippet)
I'm confident in the answer now. Let me write a clear, well-organized response. I'll note that the exact Section 125 wording comes from search snippets (NCA + foundingdocs), which is honest sourcing.
Let me structure the answer:
- Direct answer: Canberra
- Why not Sydney or Melbourne: the rivalry/compromise
- The constitutional mechanism (Section 125)
- A bit of color: it's a planned city, located in NSW but ~65 km / 100 miles from Sydney
Let me be accurate about distance: Canberra is roughly 65 km (about 40 miles) southwest of Sydney by road... wait, actually Canberra is about 65 km (40 miles) from Sydney? No. Let me think. Canberra is about 65 km (40 miles) from Sydney? Actually Canberra is roughly 65 km... no. Canberra is about 280 km (175 miles) from Sydney and about 660 km from Melbourne. Hmm, let me reconsider.
Actually: Sydney to Canberra is about 65 km? No, that's too short. Sydney to Canberra is roughly 65 km by... no. Let me get this right. Canberra is about 65 km northwest of... no.
Sydney to Canberra: approximately 65 km? That can't be right — Canberra is a separate city with its own airport, clearly more than an hour away.
The real distance: Sydney to Canberra is about 65 km? No. It's about 280 km (175 miles) by road, roughly a 3-hour drive. By air it's about 290 km. Hmm.
Wait, I need to be careful. Let me recall: Canberra is roughly 65 km (40 miles) from... no.
Let me just recall the actual figure. Canberra is located about 65 km... I keep wanting to say 65 but that's wrong.
The correct figure: Canberra is approximately 65 km? No. Sydney–Canberra is roughly 280 km (175 miles) by road. Actually I think it's closer to 65 km... no, definitely not.
I'm now uncertain about the exact distance, which is exactly the kind of "settled fact where confident memory is wrong by one detail" I should not state from memory. The Constitution says the capital must be "not less than one hundred miles from the limits of the City of Sydney" — that's the relevant legal distance and it's confirmed by the search snippets. I'll use that (labeling it as coming from the NCA/foundingdocs snippets since I couldn't open the full page) rather than risk a wrong straight-line distance.
Actually, I recall the straight-line distance Sydney–Canberra is about 280 km / 175 miles, and Melbourne–Canberra about 660 km / 410 miles. But since I'm not 100% certain and it's not essential, I'll lean on the constitutional "100 miles from Sydney" requirement which is well-sourced, and avoid stating a precise road distance I can't verify. I can say it's "located in New South Wales, between the two cities" which is safe.
Let me write the final answer now. I don't need more tool calls.
Format: This deserves a clear structure with the direct answer up top, then the reasoning. A short bulleted breakdown works well. Keep it readable, not overly long.
=== [21] ASSISTANT TEXT ===
## Canberra
The capital of Australia is **Canberra**, a purpose-built planned city in the Australian Capital Territory (ACT). It was founded in 1913 and designed by American architects Walter Burley Griffin and Marion Mahony Griffin.
## Why not Sydney or Melbourne?
It comes down to a rivalry that nearly broke Federation itself:
- **Sydney wanted the capital; Melbourne wanted the capital.** As the colonies federated in 1901, New South Wales insisted the seat of government be in Sydney, and Victoria insisted on Melbourne. At the last Federal Convention (1898) they couldn't agree, so the capital question was initially left out of the draft constitution.
- **The compromise was a brand-new city.** Neither side would accept the other's city, so the deal was to build a neutral capital *between* them rather than pick one. Crucially, it had to sit in **New South Wales** — a concession to Sydney — but it couldn't *be* Sydney — a concession to Melbourne.
- **This was written into the Constitution.** Section 125 requires the seat of government to "be in the State of New South Wales, and be distant not less than one hundred miles from the limits of the City of Sydney." That NSW requirement was the bargaining chip that helped secure Federation (per Australia's founding documents). The exact site within NSW was then chosen by the new parliament, and Canberra won over rivals like Dalmeny.
So Canberra exists precisely *because* Sydney and Melbourne were too evenly matched and too proud to share — the solution was to give both states a little: the capital is in NSW, but nowhere near either of their cities.
*(The exact Section 125 wording is from search snippets of the National Capital Authority and the Australian Founding Documents site; I couldn't open those pages directly.)*
