Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-6ab0a5b3d3bbd14c quantitative
Since April 2020
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The April 2020 start of operations is attributed to the 36Kr company profile, which is bot-walled. The trade-press account independently dates the programme to 2020: “2020 年，成都城投建设集团正式启动城市照明及智慧多功能杆改革试点” (in 2020 the Chengdu City Investment Construction Group formally launched the urban-lighting and smart-multifunction-pole reform pilot).
Caveat
Only the year 2020 is confirmed by a readable source, and it names the parent Construction Group rather than the subsidiary. The month (April) rests on the unreadable 36Kr profile.

  2. iotcomm.cn (industry trade press) — Chengdu's 180,000 streetlights get a smart upgrade, saving nearly ¥100M a year
Claim 2 clm-5e8d16205f26e7cf quantitative
a subsidiary of the state-owned Chengdu City Investment Group, founded October 2019
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The entry's own source note attributes the October 2019 founding to the 36Kr company profile. 36kr.com answers every automated client with a Volcano Engine security-check page (火山引擎 正在进行安全检测) — browser, curl, Googlebot and mobile user-agents, the r.jina.ai proxy and the mobile path all returned the same wall — so no locator could be captured. Web search confirms the company (成都城投智慧城市科技有限公司) exists, has a 36Kr venture profile page and is a City Investment Group subsidiary, but no readable page states the founding month.
Caveat
Neither the founding month nor the ownership chain could be re-read from a listed source; both rest on the bot-walled 36Kr profile.

Claim 3 clm-eb9d41e1cccd1d43 descriptive
has been replacing standalone streetlight poles, traffic-camera masts, signage and signal poles with combined 'smart multifunction poles'
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The trade-press account describes exactly this consolidation: “将道路照明、新能源充电桩、LED 信息发布屏、环境空气监测、视频监控等城市感知设备整合集成，实现一杆多用” — road lighting, charging piles, LED information screens, air monitoring and video surveillance integrated so that “one pole serves many uses”.
Caveat
No claim-specific caveat recorded

  2. iotcomm.cn (industry trade press) — Chengdu's 180,000 streetlights get a smart upgrade, saving nearly ¥100M a year
Claim 4 clm-4da397ea1277c5c9 quantitative
carrying LED lighting, 5G small cells, traffic and environmental sensors, emergency call points, phone/EV charging and (as of a 2026 rollout) roadside charging piles
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The trade-press account lists road lighting, new-energy charging piles, LED information screens, ambient-air monitoring and video surveillance on the poles: “将道路照明、新能源充电桩、LED 信息发布屏、环境空气监测、视频监控等城市感知设备整合集成”. The remaining items on the entry's list are attributed to the bot-walled 36Kr profile.
Caveat
The readable list does not mention 5G small cells, emergency call points or phone charging. The 2026 roadside-charging-pile rollout is dated by neither listed source; contemporary reporting outside the source list puts roughly 600 kerbside charging points due online by end of April 2026.

Claim 5 clm-be8f9adb4caedb87 quantitative
Over 3,500 poles were in place along corridors like Chengdu's First Ring Road, Phoenix Mountain Sports Park and East Suburb Memory
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The pole count is attributed to the bot-walled 36Kr profile. The Sichuan News URL returns HTTP 404 on every route tried, so no locator could be captured. An English republication of the same Sichuan report names the First Ring Road as built and East Suburb Memory as a corridor where broadcasting and weather monitoring were being tested, which supports the corridor list.
Caveat
Neither listed source could be opened, and the count is vintage-sensitive: independent reporting counts about 1,300 poles on the First Ring Road alone, while a 2026 vendor account claims 5,000+ citywide. Phoenix Mountain Sports Park appears in no readable account.

  2. Sichuan News (scol.com.cn) — Chengdu plans to build 30,000 smart multifunction poles by 2025
Claim 6 clm-3a242b03e2303604 quantitative
a stated plan to reach 30,000+ poles across the city within 3-5 years for roughly ¥1.5 billion
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
This is the headline claim of the Sichuan News piece, whose title survives in search indexes as “成都计划至2025年建30000根智慧多功能杆” (Chengdu plans to build 30,000 smart multifunction poles by 2025). Search snippets of the same report carry the ¥1.5 billion (15亿) figure across 23 districts and quote deputy general manager Li Yang (李洋). The Sichuan News URL returns HTTP 404 on every route tried, so no locator could be captured.
Caveat
The listed source is dead. The target is stated in the recoverable reporting as “by 2025” (the 14th Five-Year Plan period), not as a rolling 3-5 years.

Claim 7 clm-21ba0836c24286ed quantitative
a 99.38% monthly streetlight-uptime rate
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The trade-press account states it verbatim: “2021年管辖区域内照明设施月平均亮灯率达到99.38%” — in 2021 the monthly average lighting rate of lighting installations in the managed area reached 99.38%, matching the entry's “in its managed area” framing.
Caveat
The readable source dates the figure to 2021, while the entry reports it in the present tense. It is an operator/vendor figure, not an independent audit.

Claim 8 clm-e34066b792905163 quantitative
about 40% energy savings from LED retrofits versus the old sodium lamps
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The entry's source note attributes the ~40% figure to the bot-walled 36Kr profile. The trade-press account covers the same sodium-to-LED retrofit — “项目分期完成主城区老旧钠灯高光效LED 替换” — but reports a *combined* saving of 50% that also includes dimming: “依托按需分时调光、分区功率调控实现二次节能，综合节电率达 50%”.
Caveat
The two figures measure different things — LED-versus-sodium alone against LED plus demand-based dimming — so they need not conflict, but no readable listed source states 40% for the LED step by itself. Operator- or vendor-reported either way.

  2. iotcomm.cn (industry trade press) — Chengdu's 180,000 streetlights get a smart upgrade, saving nearly ¥100M a year
Claim 9 clm-21ccf20c8c837eb9 descriptive
the poles installed so far mainly just replace old streetlights; the sensor and camera functions are described as 'reserved for future use' rather than fully active
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
An English republication of the Sichuan News report renders the same point as “The smart multi-function pole built in the First Ring Road has fewer functions, but the current use of this pole makes it possible to carry more functions in the future,” and describes broadcasting and weather monitoring at East Suburb Memory as still being tested. The Sichuan News URL returns HTTP 404 on every route tried, so no locator could be captured.
Caveat
Neither listed source could be opened. “Reserved for future use” is the entry's rendering — no readable account uses the word 预留. The republication supports “fewer functions now, more possible later” but not the stronger claim that most of the capacity is reserved.

Claim 10 clm-4637f66646c84966 quantitative
3,500+ multifunction poles installed against a 30,000-pole, ¥1.5 billion, 3-5 year target
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Restates the snippet's deployment-versus-target pair. The 3,500 count comes from the bot-walled 36Kr profile; the 30,000-pole and ¥1.5 billion target is the headline of the Sichuan News report, preserved in search indexes as “成都计划至2025年建30000根智慧多功能杆”. Neither page could be opened.
Caveat
Both figures rest on unreadable sources, and the recoverable reporting frames the target as “by 2025” rather than 3-5 years.

99.38% monthly streetlight-activation rate
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Same figure as in the snippet, stated verbatim by the trade-press account: “2021年管辖区域内照明设施月平均亮灯率达到99.38%”. 亮灯率 is literally “lit-lamp rate”, which is what the entry renders as “activation rate”.
Caveat
Dated to 2021 in the readable source; reported without a year in the entry.

Claim 12 clm-66f439ce195abb34 quantitative
~40% energy savings vs. sodium lamps in the company's managed area (operator-reported)
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Same figure as in the snippet. The trade-press account covers the identical sodium-to-LED programme (“项目分期完成主城区老旧钠灯高光效LED 替换”) but gives a combined 50% including dimming. The entry's own “(operator-reported)” label is accurate: every readable figure in this family is self-reported by the operator or its equipment vendor.
Caveat
No readable listed source gives 40% for the LED step alone; the vendor account gives 50% for LED plus dimming.

Claim 13 clm-3e2b782cd06727c2 descriptive
Chengdu's own operator admits most of the smart hardware capacity is 'reserved,' not yet switched on
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The operator-sourced reporting behind this is the Sichuan News piece; an English republication of it says “The smart multi-function pole built in the First Ring Road has fewer functions, but the current use of this pole makes it possible to carry more functions in the future,” with broadcasting and weather monitoring still under test at East Suburb Memory. The Sichuan News URL returns HTTP 404 on every route tried, so no locator could be captured.
Caveat
“Admits” and “most of the capacity” are the entry's framing. The recoverable reporting supports “fewer functions today, more possible later”; it does not quantify how much capacity sits idle, and no readable source uses the word 预留 (reserved).
